Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, and in particular to a control method and device for energy storage devices, a readable storage medium and an energy storage device. Background Art

[0002] The energy storage device can expand its capacity by increasing the number of battery packs. Multiple battery packs are stacked together, and two adjacent battery packs are connected by plug-in connectors. However, the battery pack at the bottom is at risk of water ingress, and liquid may enter the battery pack through the connector at the bottom of the battery pack.

[0003] In the related art, a bulky base needs to be installed at the bottom of the lowest battery pack to reduce the probability of liquid entering the battery pack through the base.

[0004] However, the bulky base will increase the weight of the energy storage device, making it inconvenient to carry. At the same time, the large-sized base will increase the space required for the energy storage device, making it more difficult to arrange the energy storage device, so that the energy storage device has a technical problem of poor practicality. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, a first aspect of the present invention provides a control method for an energy storage device.

[0007] A second aspect of the present invention provides a control device for an energy storage device.

[0008] A third aspect of the present invention provides a control device for an energy storage device.

[0009] A fourth aspect of the present invention provides a readable storage medium.

[0010] A fifth aspect of the present invention provides an energy storage device.

[0011] In view of this, a first aspect of the present invention provides a control method for an energy storage device, the energy storage device comprising a battery box and a detection device, the bottom of the battery box comprising an opening, and the control method comprising:

[0012] Based on the detection device being connected to the battery box, the detection device is controlled to be turned on;

[0013] When the detection device detects the presence of liquid under the opening, the energy storage device is controlled to issue a warning message.

[0014] The present invention provides a control method for an energy storage device, which is used to control the operation of the energy storage device. A large amount of electric energy is stored in the energy storage device. After the energy storage device is connected to an electric device, the energy storage device can supply power to the electric device.

[0015] Specifically, the energy storage device includes a battery box. The battery box serves as an energy storage unit in the energy storage device. The energy storage capacity of the energy storage device can be increased by increasing the number of battery boxes. For example, when the energy demand is small, the user can carry a single battery box to meet the working needs of the applied electrical equipment. When the energy demand is large, multiple battery boxes can be carried and stacked together to power the applied electrical equipment through the multiple battery boxes. An opening is provided at the bottom of the battery box.

[0016] Among them, when the battery box is arranged at the bottom, the opening at the bottom of the battery box is close to the ground. At this time, the liquid accumulated on the ground may enter the box through the opening, causing the battery box to have short circuit, leakage and other faults, affecting the safety and reliability of the energy storage equipment.

[0017] In this regard, the present application also provides a detection device, which includes a first detection element. The detection device can detect whether there is liquid at the bottom of the waterproof plug through the first detection element.

[0018] On this basis, the control method of the battery box includes, after the battery box is assembled and the detection device is connected to the bottom battery box through an electrical connection, the detection device is controlled to be turned on so that the detection device can perform detection at the opening of the bottom battery box. During the operation, the power supply work of the battery box and the detection work of the detection device are performed simultaneously.

[0019] After the control detection device is turned on, it can be determined whether there is liquid under the opening based on the electrical signal fed back by the detection device. When it is determined that there is liquid under the opening based on the electrical signal, the energy storage device is controlled to issue a warning message to remind the user that there is liquid under the opening and that there is a risk of water immersion in the battery box at the bottom, so that the user can promptly check the risk of water immersion, such as moving the energy storage device to a dry place or wiping off the accumulated water under the opening.

[0020] Among them, the warning information can be sound and light information, and can also be a push message sent to the user's personal terminal. For this, the technical solution does not impose a rigid limit on the specific type of warning information, and it is sufficient to meet the warning prompt requirements.

[0021] It can be seen that the present application realizes the detection of hidden dangers of water immersion and reduces the probability of water entering the battery box by setting the above-mentioned control method. Moreover, compared with the base solution in the related art, the detection device provided by the present application can meet the waterproof requirements of the opening without destroying the portability of the energy storage device and increasing the difficulty of arranging the energy storage device, thereby solving the technical problem of poor practicality of the energy storage device existing in the related art. At the same time, the above-mentioned control method executed in conjunction with the detection device can realize the detection of hidden dangers of water immersion that cannot be achieved by the base in the related art, so as to enhance the waterproof performance of the energy storage device and reduce the failure rate of the energy storage device. Thereby achieving the technical effect of optimizing the structure of the energy storage device, improving the safety and reliability of the energy storage device, and improving the user experience.

[0022] In addition, the control method of the energy storage device provided by the present invention may also have the following additional technical features:

[0023] In some technical solutions of the present invention, optionally, the warning information includes first warning information, and when the detection device detects that there is liquid below the opening, the step of controlling the energy storage device to issue the warning information includes:

[0024] When the detection device detects that there is liquid below the opening and there is no liquid inside the opening, the energy storage device is controlled to issue a first warning message;

[0025] Among them, the first warning information is used to indicate that the energy storage equipment is at risk of flooding.

[0026] In this technical solution, the detection device can not only detect whether there is liquid below the opening through electrical signals, but also detect whether there is liquid inside the opening through electrical signals. The warning information includes the first warning information, which is used to remind the user that the energy storage device is currently at risk of flooding. When the user receives the first warning information, it proves that there is liquid below the energy storage device, but the liquid has not yet risen to the inside of the opening. The user can eliminate the flooding hazard in time based on the first warning information.

[0027] On this basis, when the detection device detects that there is liquid below the opening, the steps of controlling the energy storage device to issue a warning message specifically include:

[0028] After the control detection device is turned on, if it can be determined based on the electrical signal fed back by the detection device that there is liquid below the opening and no liquid is inside the opening, it means that liquid has accumulated below the opening, but the accumulated liquid level has not yet risen to the height of the opening. The energy storage device is then controlled to issue a first warning message to remind the user that there is currently a risk of water immersion in the energy storage device, and the risk of water immersion needs to be eliminated in time to prevent the liquid level from further rising and entering the interior of the battery box through the opening.

[0029] It can be seen that by limiting the above control method, accurate detection of water flooding risk of energy storage equipment can be achieved, ensuring that users can eliminate water flooding risk in a timely manner through the first warning information, thereby reducing the probability of water flooding failure of energy storage equipment, and further achieving the technical effect of improving the intelligence level of energy storage equipment and reducing the failure rate of energy storage equipment.

[0030] In some technical solutions of the present invention, optionally, the detection device includes a first detection element, the first detection element is arranged below the opening, and the step of controlling the detection device to open includes:

[0031] detecting a first resistance value of a first detection element;

[0032] Determining that no liquid exists below the opening based on the first resistance value being greater than or equal to a first threshold value;

[0033] Based on the first resistance value being less than the first threshold, it is determined that liquid exists below the opening.

[0034] In this technical solution, the detection device includes a first detection element. The detection device can determine whether there is liquid under the opening by detecting a first resistance value of the first detection element. The first resistance value of the first detection element will change when it comes into contact with liquid, and the first resistance value corresponds to the aforementioned electrical signal.

[0035] On this basis, the steps of controlling the detection device to start specifically include:

[0036] After the detection device is powered on, the first resistance value of the first detection element is detected in real time. When the detected first resistance value is greater than or equal to the first threshold value, it means that the first detection element has not been in contact with liquid. At this time, there is no liquid under the opening, the energy storage device is not at risk of flooding, and the battery box can operate normally. Correspondingly, when the detected first resistance value is less than the first threshold value, it means that the first detection element has been in contact with liquid. At this time, there is liquid under the opening, and the energy storage device is at risk of flooding. The energy storage device is then controlled to issue a first warning message or cooperate with the second detection element to issue a second warning message.

[0037] It can be seen that the above control method can monitor the liquid below the opening by monitoring the first resistance value of the first detection element, so that the energy storage device can respond in time when liquid appears below, thereby reducing the probability of water ingress failure in the energy storage device and achieving the technical effect of improving the intelligence level of the energy storage device.

[0038] Specifically, the first detection element includes a first metal wire and a second metal wire, and the first metal wire and the second metal wire are arranged side by side at the bottom of the bracket.

[0039] During operation, the resistance between the first metal wire and the second metal wire is detected. When the first metal wire and the second metal wire are not in contact with the liquid, the first metal wire and the second metal wire are insulated and have a relatively large resistance (greater than 1000KΩ). When the first metal wire and the second metal wire are in contact with the liquid below the opening, water is conducted between the first metal wire and the second metal wire, and the resistance becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ.

[0040] In some technical solutions of the present invention, optionally, the warning information further includes second warning information, and when the detection device detects that there is liquid below the opening, the step of controlling the energy storage device to issue the warning information includes:

[0041] When the detection device detects that there is liquid below the opening and there is liquid inside the opening, the energy storage device is controlled to issue a second warning message;

[0042] The second warning information is used to indicate that a water immersion failure has occurred in the energy storage device.

[0043] In this technical solution, the warning information includes a first warning information, and the second warning information is used to remind the user that there is a risk of water ingress to the energy storage device. When the user receives the second warning information, it proves that liquid has entered the opening and the energy storage device may experience a water ingress failure at any time.

[0044] On this basis, when the detection device detects that there is liquid below the opening, the steps of controlling the energy storage device to issue a warning message specifically include:

[0045] After the control detection device is turned on, if it can be determined based on the electrical signal fed back by the detection device that there is liquid below the opening, and there is also liquid on the inside of the opening, it means that the liquid has entered the opening. The energy storage device is then controlled to issue a second warning message to remind the user that there is currently a risk of water ingress to the energy storage device, and the risk of water immersion needs to be eliminated in time to avoid irreparable losses to the energy storage device.

[0046] It can be seen that by limiting the above control method, accurate detection of water ingress risk of energy storage equipment can be achieved, ensuring that users can eliminate water ingress risk in a timely manner through the second warning information, thereby reducing the probability of water ingress failure of the energy storage equipment, and further achieving the technical effect of improving the intelligence level of the energy storage equipment and reducing the failure rate of the energy storage equipment.

[0047] In some technical solutions of the present invention, optionally, the detection device further includes a second detection element, and the second detection element is disposed in the opening. The step of controlling the detection device to open includes:

[0048] detecting a second resistance value of a second detection element;

[0049] determining that no liquid exists in the opening based on the second resistance value being greater than or equal to a second threshold;

[0050] Based on the second resistance value being less than the second threshold value, it is determined that liquid exists in the opening.

[0051] In this technical solution, the detection device includes a second detection element. The detection device can determine whether there is liquid inside the opening by detecting the second resistance value of the second detection element. The second resistance value of the second detection element will change when it comes into contact with the liquid, and the second resistance value corresponds to the aforementioned electrical signal.

[0052] On this basis, the steps of controlling the detection device to start specifically include:

[0053] After the detection device is powered on, the second resistance value of the first detection element is detected in real time. When the detected second resistance value is greater than or equal to the second threshold value, it means that the second detection element has not been in contact with liquid. At this time, there is no liquid inside the opening, and there is no risk of water entering the energy storage device. The battery box can work normally. Correspondingly, when the detected second resistance value is less than the second threshold value, it means that the second detection element has been in contact with liquid. At this time, there is liquid inside the opening, and there is a risk of water entering the energy storage device. The energy storage device is then controlled to issue a second warning message.

[0054] It can be seen that the above control method can monitor the liquid below the opening by monitoring the second resistance value of the second detection element, so that the energy storage device can respond in time when liquid appears inside the opening, thereby reducing the probability of water ingress failure in the energy storage device and achieving the technical effect of improving the intelligence level of the energy storage device.

[0055] Specifically, the second detection element includes a third metal wire and a fourth metal wire, and the third metal wire and the fourth metal wire are arranged side by side inside the opening.

[0056] During operation, the resistance between the third metal wire and the fourth metal wire is detected. When the third metal wire and the fourth metal wire are not in contact with the liquid, the third metal wire and the fourth metal wire are insulated and have a relatively large resistance (greater than 1000KΩ); when the third metal wire and the fourth metal wire are in contact with the liquid inside the opening, water is conducted between the third metal wire and the fourth metal wire, and the resistance becomes smaller (less than 1000KΩ, and can usually be reduced to less than 100KΩ).

[0057] In some technical solutions of the present invention, optionally, after the step of controlling the energy storage device to issue a warning message, the control method further includes:

[0058] Control the battery box to cut off power and control the alarm device to work;

[0059] Wherein, the alarm device includes: an LED light and / or a buzzer.

[0060] In this technical solution, when the energy storage device issues a warning message based on the electrical signal fed back by the detection device, the energy storage device controls the battery box to cut off power and simultaneously starts the backup power supply to supply power to the alarm device on the energy storage device through the backup power supply and control the alarm device to start working. The alarm device is used to increase the probability of users knowing that the energy storage device has a fault, so that users can arrive in time and eliminate hidden dangers.

[0061] It can be seen that by limiting the above-mentioned control method, the energy storage device can be powered off in time when there is a risk of flooding or water ingress, so as to avoid irreparable losses of the energy storage device. At the same time, the alarm device can increase the probability of users knowing hidden dangers, reminding users to eliminate hidden dangers in time and restore the normal operation of the energy storage device, thereby achieving the technical effect of improving the automation and intelligence level of the energy storage device and improving the safety of the energy storage device.

[0062] A second aspect of the present invention provides a control device for an energy storage device, the energy storage device comprising a battery box and a detection device, the bottom of the battery box comprising an opening, the control device comprising: a first control module, for controlling the detection device to turn on based on the detection device being connected to the battery box; and a second control module, for controlling the energy storage device to issue an early warning message when the detection device detects the presence of liquid below the opening.

[0063] The present invention provides a control device for an energy storage device, which is used to control the operation of the energy storage device. A large amount of electric energy is stored in the energy storage device. After the energy storage device is connected to an electric device, the energy storage device can supply power to the electric device.

[0064] Specifically, the energy storage device includes a battery box. The battery box serves as an energy storage unit in the energy storage device. The energy storage capacity of the energy storage device can be increased by increasing the number of battery boxes. For example, when the energy demand is small, the user can carry a single battery box to meet the working needs of the applied electrical equipment. When the energy demand is large, multiple battery boxes can be carried and stacked together to power the applied electrical equipment through the multiple battery boxes. An opening is provided at the bottom of the battery box.

[0065] Among them, when the battery box is arranged at the bottom, the opening at the bottom of the battery box is close to the ground. At this time, the liquid accumulated on the ground may enter the box through the opening, causing the battery box to have short circuit, leakage and other faults, affecting the safety and reliability of the energy storage equipment.

[0066] In this regard, the present application also provides a detection device, which includes a first detection element. The detection device can detect whether there is liquid at the bottom of the waterproof plug through the first detection element.

[0067] On this basis, the control device of the battery box includes a first control module and a second control module. After the battery box is assembled and the detection device is connected to the bottom battery box through an electrical connection, the first control module controls the detection device to start, so that the detection device can perform detection at the opening of the bottom battery box. During the working process, the power supply work of the battery box and the detection work of the detection device are carried out simultaneously.

[0068] After the control detection device is turned on, the second control module can determine whether there is liquid under the opening based on the electrical signal fed back by the detection device. When it is determined that there is liquid under the opening based on the electrical signal, the second control module controls the energy storage device to issue a warning message to remind the user that there is liquid under the opening and that the battery box at the bottom is at risk of flooding, so that the user can promptly check the risk of flooding, such as moving the energy storage device to a dry place or wiping off the accumulated water under the opening.

[0069] Among them, the warning information can be sound and light information, and can also be a push message sent to the user's personal terminal. For this, the technical solution does not impose a rigid limit on the specific type of warning information, and it is sufficient to meet the warning prompt requirements.

[0070] It can be seen that the present application realizes the detection of hidden dangers of water immersion and reduces the probability of water entering the battery box by setting the above-mentioned control device. Moreover, compared with the base solution in the related art, the detection device provided by the present application can meet the waterproof requirements of the opening without destroying the portability of the energy storage device and increasing the difficulty of arranging the energy storage device, thereby solving the technical problem of poor practicality of the energy storage device existing in the related art. At the same time, the above-mentioned control device executed in conjunction with the detection device can realize the detection of hidden dangers of water immersion that the base in the related art cannot achieve, so as to enhance the waterproof performance of the energy storage device and reduce the failure rate of the energy storage device. Thereby achieving the technical effect of optimizing the structure of the energy storage device, improving the safety and reliability of the energy storage device, and improving the user experience.

[0071] The third aspect of the present invention provides a control device for an energy storage device, the control device for the energy storage device comprising: a memory, in which a program or instruction is stored; a processor, which executes the program or instruction stored in the memory to implement the steps of the control method of the energy storage device in any of the above technical solutions.

[0072] In this technical solution, a control device for an energy storage device is proposed. The control device for the energy storage device includes a memory and a processor. The processor executes the program or instruction stored in the memory to implement the control method for the energy storage device in any of the above technical solutions. Therefore, the control device for the energy storage device has the advantages of the control method for the energy storage device in any of the above technical solutions, and can achieve the technical effects that can be achieved by the control method for the energy storage device in any of the above technical solutions. To avoid repetition, it will not be repeated here.

[0073] A fourth aspect of the present invention provides a readable storage medium storing a program or instruction, which, when executed by a processor, implements the steps of the control method in any of the above technical solutions.

[0074] In this technical solution, a readable storage medium is proposed, which stores a program or instruction. The program or instruction is executed by a processor to implement the steps of the control method of the energy storage device in any of the above technical solutions. Therefore, the readable storage medium has the advantages of the control method of the energy storage device in any of the above technical solutions, and can achieve the technical effects that can be achieved by the control method of the energy storage device in any of the above technical solutions. To avoid repetition, it will not be repeated here.

[0075] A fifth aspect of the present invention provides an energy storage device, the energy storage device comprising: a control device for the energy storage device in any of the above technical solutions, and / or a readable storage medium in the above technical solutions.

[0076] In this technical solution, an energy storage device including the control device in any of the above technical solutions and / or the readable storage medium in the above technical solution is proposed, so the energy storage device has the advantages of the control device in any of the above technical solutions and can achieve the technical effects that can be achieved by the control device in any of the above technical solutions, and / or the energy storage device has the advantages of the readable storage medium in the above technical solution and can achieve the technical effects that can be achieved by the readable storage medium in the above technical solution. To avoid repetition, it will not be repeated here.

[0077] In some technical solutions of the present invention, optionally, the energy storage device includes: a battery box, the battery box includes a box body and a first connector, the bottom of the box body includes an opening, and the first connector is arranged at the opening; a sealing component, the sealing component includes a waterproof plug and a detection device, the detection device is arranged at the waterproof plug, the waterproof plug is detachably connected to the opening, and when the waterproof plug is installed in the opening, the detection device is electrically connected to the first connector; wherein the detection device includes a first detection element, and the detection device is used to detect whether there is liquid at the bottom of the waterproof plug through the first detection element.

[0078] In this technical solution, an energy storage device is proposed, in which a large amount of electrical energy is stored. After the energy storage device is connected to an electrical device, the energy storage device can supply power to the electrical device.

[0079] Specifically, the energy storage device includes a battery box. The battery box serves as an energy storage unit in the energy storage device. The energy storage capacity of the energy storage device can be increased by increasing the number of battery boxes. For example, when the energy demand is small, the user can carry a single battery box to meet the working needs of the applied electrical equipment. When the energy demand is large, multiple battery boxes can be carried and stacked together to power the corresponding electrical equipment through multiple battery boxes.

[0080] The battery box includes a box body and a first connector. The box body forms the outer surface of the battery box, and the box body can provide shielding and protection for the internal structure of the battery box to reduce the failure rate of the battery box. An opening is provided at the bottom of the battery box, and the first connector is provided at the opening. Correspondingly, a second connector is also provided at the top of the box body, and the second connector is adapted to the first connector.

[0081] When multiple battery boxes need to be stacked together, the battery box located on the top is plugged together with the second connector of the battery box located on the bottom through the first connector to complete the electrical connection between two adjacent battery boxes. Similarly, the energy storage capacity of the energy storage device can be increased by increasing the number of stacked battery boxes.

[0082] Among them, when the battery box is arranged at the bottom, the opening at the bottom of the battery box is close to the ground. At this time, the liquid accumulated on the ground may enter the box through the opening, causing the battery box to have short circuit, leakage and other faults, affecting the safety and reliability of the energy storage equipment.

[0083] In this regard, the present application also provides a sealing component, which includes a waterproof plug. The waterproof plug can be detachably arranged at the opening. When the waterproof plug is installed at the opening, the waterproof plug can seal the opening to reduce the probability of liquid entering the opening, thereby realizing a waterproof design of the bottom battery box.

[0084] Among them, the waterproof plug can prevent liquid that approaches the opening for a short time from entering the opening to a certain extent. However, when liquid accumulates under the waterproof plug for a long time and there is a risk of the waterproof plug being soaked by the liquid, the hidden danger of failure of the battery box cannot be eliminated by the waterproof plug alone.

[0085] In this regard, the present application also provides a detection device on the waterproof plug, which includes a first detection element. The detection device can detect whether there is liquid at the bottom of the waterproof plug through the first detection element. When the detection device determines that there is liquid at the bottom of the waterproof plug, it can control the battery box to cut off power or issue a water immersion alarm in time to avoid irreversible failure of the energy storage device, and at the same time remind the user to move the energy storage device in time to eliminate the risk of water immersion.

[0086] It can be seen that the present application reduces the probability of liquid entering the opening by providing a waterproof plug, and at the same time realizes the detection of water immersion hazards by providing a detection device, further reducing the probability of water entering the battery box. In addition, compared with the base solution in the related art, the waterproof plug provided by the present application is smaller in size and weight, and can meet the waterproof requirements of the opening without destroying the portability of the energy storage device and increasing the difficulty of arranging the energy storage device, thereby solving the technical problem of poor practicality of the energy storage device in the related art. At the same time, by providing a detection device, the present application can realize the detection of water immersion hazards that cannot be achieved by the base in the related art, so as to enhance the waterproof performance of the energy storage device and reduce the failure rate of the energy storage device. Thereby achieving the technical effect of optimizing the structure of the energy storage device, improving the safety and reliability of the energy storage device, and improving the user experience.

[0087] In some technical solutions of the present invention, optionally, the waterproof plug includes a bracket, and when the waterproof plug is installed at the opening, the bracket blocks the opening, and the detection device also includes: a detection unit, the detection unit is arranged on a side of the bracket facing the battery box, and when the waterproof plug is installed at the opening, the detection unit is electrically connected to the first connector, and the detection unit includes a first interface; wherein the first detection element is arranged on a side of the waterproof plug facing away from the battery box, and the first detection element is connected to the first interface.

[0088] In this technical solution, the waterproof plug includes a bracket, the shape of the bracket is adapted to the shape of the opening, and when the waterproof component is installed in the opening, the bracket is partially embedded in the opening.

[0089] On this basis, the detection device also includes a detection unit, which is arranged on a bracket. The bracket is used to position and support the detection unit. Specifically, the detection unit is arranged on the side of the bracket facing the battery box. The bracket can also play a water-proof role to prevent the detection unit from being damaged due to contact with liquid.

[0090] Among them, the first detection element is arranged below the bracket, and the first detection element is electrically connected to the detection unit through a line connection to the first interface on the detection unit. After the assembly of the sealing component is completed, the detection unit is connected to the first connector, and the battery box can power the detection unit and the first detection element through the first connector, so that the first detection element can detect whether there is liquid under the bracket on the outside of the bracket.

[0091] It can be seen that by setting up the bracket, waterproof protection can be provided for the inner detection unit to prevent liquid from corroding the detection unit, ensuring that the detection result of the detection unit is accurate. At the same time, the bracket can position the first detection element under the battery box so that the first detection element can be close to the ground, thereby improving the accuracy and timeliness of water immersion detection, and achieving the technical effect of improving the safety and reliability of energy storage equipment and reducing the failure rate of energy storage equipment.

[0092] In some technical solutions of the present invention, optionally, the first detection element includes: a first metal wire; a second metal wire, the first metal wire and the second metal wire are arranged side by side on a side of the bracket facing away from the battery box, and when the first metal wire and the second metal wire contact liquid, the detection unit generates a first electrical signal.

[0093] In this technical solution, the first detection element includes a first metal wire and a second metal wire, which are arranged side by side at the bottom of the bracket. After the sealing component is assembled, the first metal wire and the second metal wire are located below the opening to ensure that the first detection element can detect the risk of water immersion before the water level of the liquid rises to the opening.

[0094] Specifically, the first metal wire and the second metal wire are both electrically connected to a first interface of the detection unit.

[0095] During operation, the detection unit detects the resistance between the first metal wire and the second metal wire. When the first metal wire and the second metal wire are not in contact with the liquid, the first metal wire and the second metal wire are insulated and have a relatively large resistance (greater than 1000KΩ). When the first metal wire and the second metal wire are in contact with the liquid below the opening, water is conducted between the first metal wire and the second metal wire, and the resistance becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ. The information of the reduced resistance is transmitted to the detection unit as a first electrical signal.

[0096] Correspondingly, when the detection unit does not receive the first electrical signal, the detection unit outputs the first low level to the first connector, and the control circuit in the battery box can determine that there is no risk of flooding in the energy storage device through the first low level output by the detection unit, and control the energy storage device to work normally. Conversely, when the detection unit receives the first electrical signal, the detection unit outputs the first high level to the first connector, and the control circuit in the battery box can determine that there is a risk of flooding in the energy storage device through the first high level output by the detection unit, so that the control circuit can determine whether to control the energy storage device to be powered off according to the flooding risk, and determine whether an alarm needs to be issued.

[0097] It can be seen that the present application realizes the water immersion detection function below the opening by setting the first metal wire and the second metal wire, so that the energy storage device can detect the water immersion risk in time according to the first electrical signal and reduce the loss caused by the water immersion risk, thereby achieving the technical effect of improving the safety and reliability of the energy storage device and improving the intelligence level of the energy storage device.

[0098] In some technical solutions of the present invention, optionally, the waterproof plug further includes a waterproof ring, and when the waterproof plug is installed in the opening, the waterproof ring is located between the opening and the bracket, the detection unit further includes a second interface, and the detection device further includes:

[0099] The second detection element is connected to the second interface and is arranged in the waterproof ring. The detection device is used to detect whether there is liquid in the opening through the second detection element.

[0100] In this technical solution, a waterproof ring is sleeved on the bracket, and specifically, a ring-shaped convex rib is set on the top of the bracket, and the waterproof ring is sleeved around the convex rib. After the sealing component is assembled, the waterproof ring is located between the bracket and the opening. The waterproof ring can seal the bracket and the opening by filling the gap between the opening and the bracket to reduce the probability of liquid entering the inner side of the opening.

[0101] On this basis, the detection device also includes a second detection element, which is arranged on the waterproof ring, and the second detection element is connected to the second interface on the detection unit through a line, so that the second detection element is electrically connected to the detection unit. After the sealing component is assembled, the detection unit is connected to the first connector, and the battery box can supply power to the detection unit and the second detection element through the first connector, so that the second detection element can detect whether there is liquid entering the opening from the inside of the opening.

[0102] It can be seen that by arranging a second detection element on the waterproof ring, the detection device can detect whether liquid has entered the inside of the opening, thereby accurately controlling the water ingress of the opening, and timely controlling the power off of the energy storage device and sounding an alarm when it is determined that water has entered the inside of the opening, thereby reducing the failure rate of the energy storage device and reducing water ingress losses, thereby achieving the technical effect of improving the safety and reliability of the energy storage device.

[0103] In some technical solutions of the present invention, optionally, the second detection element includes: a third metal wire; a fourth metal wire, the third metal wire and the fourth metal wire are arranged side by side on the peripheral side of the waterproof ring, and when the third metal wire and the fourth metal wire contact the liquid, the detection unit generates a second electrical signal.

[0104] In this technical solution, the first detection element includes a third metal wire and a fourth metal wire, and the third metal wire and the fourth metal wire are arranged side by side at the root of the waterproof ring. After the sealing component is assembled, the third metal wire and the fourth metal wire are located on the inside of the opening and close to the lower end of the opening to ensure that the second detection element can detect the risk of water ingress at the first time when water enters the opening.

[0105] Specifically, the third metal wire and the fourth metal wire are both electrically connected to the second interface of the detection unit.

[0106] During operation, the detection unit detects the resistance between the third metal wire and the fourth metal wire. When the third metal wire and the fourth metal wire are not in contact with the liquid, the third metal wire and the fourth metal wire are insulated and have a relatively large resistance (greater than 1000KΩ). When the third metal wire and the fourth metal wire are in contact with the liquid on the inner side of the opening, water is conducted between the third metal wire and the fourth metal wire, and the resistance becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ. The information of the reduced resistance is transmitted to the detection unit as a second electrical signal.

[0107] Correspondingly, when the detection unit does not receive the second electrical signal, the detection unit outputs the second low level to the first connector, and the control circuit in the battery box can determine that the opening has not been flooded by the second low level output by the detection unit, and control the energy storage device to work normally. Conversely, when the detection unit receives the second electrical signal, the detection unit outputs the second high level to the first connector, and the control circuit in the battery box can determine that the opening has been flooded by the second high level output by the detection unit, so that the control circuit can control the energy storage device to power off according to the risk of water ingress, and control the energy storage device to sound an alarm.

[0108] It can be seen that the present application realizes water ingress detection on the inside of the opening by setting the third metal wire and the fourth metal wire, so that the energy storage device can timely detect the risk of water ingress at the opening according to the second electrical signal and reduce the loss caused by the risk of water ingress, thereby achieving the technical effect of improving the safety and reliability of the energy storage device and improving the intelligence level of the energy storage device.

[0109] Specifically, the first detection element and the second detection element work together. When the control circuit only receives the first low level and the second low level, it means that there is no liquid accumulated under the opening and no liquid enters the inside of the opening. At this time, the working environment of the energy storage device is relatively safe and the energy storage device can be controlled to work normally.

[0110] When the control circuit receives the first high level and the second low level, it indicates that liquid is accumulated under the opening and there is a risk of flooding, but the liquid level has not risen to the opening. At this time, the energy storage device can be controlled to work normally and a flood alarm can be issued to the user at the same time to remind the user to eliminate the risk of flooding in time, such as wiping the liquid under the energy storage device or moving the energy storage device to a dry place.

[0111] When the control circuit receives the first high level and the second high level at the same time, it indicates that the liquid level has risen to the opening. The control circuit then controls the energy storage device to cut off power and sends a water ingress alarm to the user to reduce water ingress losses and remind the user to eliminate the water ingress fault in time.

[0112] It can be seen that by providing the first detection element and the second detection element that work in coordination, the intelligence and automation of the energy storage device are improved, and the safety and reliability of the energy storage device are improved.

[0113] In some technical solutions of the present invention, optionally, the first connector includes: a cover body, which covers the opening on the inner side of the box body; and a first terminal, which is arranged on a side of the cover body facing the opening, and the first terminal can be electrically connected to the detection unit.

[0114] In this technical solution, the first connector includes a cover body and a first terminal.

[0115] The cover is installed inside the box body. After assembly, the cover is buckled with the opening at the bottom of the box body on the inside of the box body. The first terminal is installed in the cover body. The cover body can provide positioning and support for the first terminal. After assembly, the first terminal is aligned with the opening. When the sealing component is assembled to the opening, the first terminal is electrically connected to the detection device on the sealing component, so that the battery box can power the detection device to achieve water immersion risk detection and water ingress risk detection of the opening.

[0116] On the one hand, the cover can play a role in positioning the first terminal, so that the first terminal can be accurately positioned at a predetermined position, thereby ensuring the connection reliability between the first terminal and the detection device. On the other hand, the cover can serve as the last waterproof barrier of the battery box. When liquid enters the inner side of the cover through the opening, the cover can block the liquid and reduce the probability of liquid diffusing to the outside of the cover, thereby improving the waterproof performance of the energy storage device and achieving the technical effect of improving the safety and reliability of the energy storage device.

[0117] In some technical solutions of the present invention, optionally, the energy storage device also includes: a control circuit, the control circuit is arranged in a box, and the control circuit includes a first power supply terminal and a first ground terminal; wherein the first terminal includes a first connection terminal, a second connection terminal and a first signal terminal, the first connection terminal is used to connect to the first power supply terminal, the second connection terminal is used to connect to the first ground terminal, and the first signal terminal is used to connect to the first ground terminal through a resistor.

[0118] In this technical solution, a control circuit is provided in the battery box, and the control circuit is connected to the storage battery in the battery box to control the charging and discharging process of the storage battery.

[0120] The first signal terminal is connected to the first ground terminal through a resistor. After the sealing component is assembled, the first signal terminal is connected to the detection circuit in the detection device, and the control circuit can receive the first low level, the second low level, the first high level and the second high level through the first signal terminal, so that the control circuit can timely judge the risk according to the above electrical signals and timely adjust the working state of the energy storage device, thereby achieving the technical effect of improving the intelligence level of the energy storage device and improving the safety and reliability of the energy storage device.

[0121] In some technical solutions of the present invention, optionally, the detection device further includes: a second terminal, the second terminal is arranged on the bracket, the second terminal is connected to the detection unit, and the second terminal can be connected to the first terminal.

[0122] In this technical solution, the detection device also includes a second terminal, which is electrically connected to the detection device and is arranged on a side of the bracket facing the battery box. The second terminal is adapted to the first terminal, and after the sealing component is assembled, the first terminal and the second terminal are butt-jointed together.

[0123] By providing a second terminal that can be plugged into and connected to the first terminal, the electrical connection can be synchronously completed when the sealing component is embedded in the opening, thereby reducing the complexity of disassembly and assembly of the sealing component and achieving the technical effect of improving the user experience.

[0124] In some technical solutions of the present invention, optionally, the energy storage device also includes: the detection unit includes a detection circuit, the detection circuit includes a second power supply terminal and a second ground terminal; wherein the second terminal includes a third connection terminal, a fourth connection terminal and a second signal terminal, the third connection terminal is used to connect to the second power supply terminal, the third connection terminal can be connected to the first connection terminal, the fourth connection terminal is used to connect to the second ground terminal, the fourth connection terminal can be connected to the second connection terminal, the second signal terminal is used to connect to the second ground terminal through a resistor, and the second signal terminal can be connected to the first signal terminal.

After the sealing component is assembled, the third connection terminal is plugged into the first connection terminal, and the fourth connection terminal is plugged into the second connection terminal, thereby realizing the electrical connection between the control circuit and the detection circuit, so that the control circuit can supply power to the detection device, so that the detection device can start water immersion risk detection and water ingress risk detection.

[0127] Among them, the second signal end is connected to the detection circuit.

DETAILED DESCRIPTION

[0149] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0150] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0151] Refer to the following Figures 1 to 14 A control method, an apparatus, a readable storage medium and an energy storage device according to some embodiments of the present invention are described.

[0152] like Figure 1 As shown, an embodiment of the present invention provides a control method for an energy storage device, the energy storage device includes a battery box and a detection device, the bottom of the battery box includes an opening, and the control method includes:

[0153] Step 102, based on the detection device being connected to the battery box, controlling the detection device to start;

[0154] Step 104: When the detection device detects that there is liquid below the opening, the energy storage device is controlled to issue a warning message.

[0155] The present invention provides a control method for an energy storage device, which is used to control the operation of the energy storage device. A large amount of electric energy is stored in the energy storage device. After the energy storage device is connected to an electric device, the energy storage device can supply power to the electric device.

[0156] Specifically, the energy storage device includes a battery box. The battery box serves as an energy storage unit in the energy storage device. The energy storage capacity of the energy storage device can be increased by increasing the number of battery boxes. For example, when the energy demand is small, the user can carry a single battery box to meet the working needs of the applied electrical equipment. When the energy demand is large, multiple battery boxes can be carried and stacked together to power the applied electrical equipment through the multiple battery boxes. An opening is provided at the bottom of the battery box.

[0157] Among them, when the battery box is arranged at the bottom, the opening at the bottom of the battery box is close to the ground. At this time, the liquid accumulated on the ground may enter the box through the opening, causing the battery box to have short circuit, leakage and other faults, affecting the safety and reliability of the energy storage equipment.

[0158] In this regard, the present application also provides a detection device, which includes a first detection element. The detection device can detect whether there is liquid at the bottom of the waterproof plug through the first detection element.

[0159] On this basis, the control method of the battery box includes, after the battery box is assembled and the detection device is connected to the bottom battery box through an electrical connection, the detection device is controlled to be turned on so that the detection device can perform detection at the opening of the bottom battery box. During the operation, the power supply work of the battery box and the detection work of the detection device are performed simultaneously.

[0160] After the control detection device is turned on, it can be determined whether there is liquid under the opening based on the electrical signal fed back by the detection device. When it is determined that there is liquid under the opening based on the electrical signal, the energy storage device is controlled to issue a warning message to remind the user that there is liquid under the opening and that there is a risk of water immersion in the battery box at the bottom, so that the user can promptly check the risk of water immersion, such as moving the energy storage device to a dry place or wiping off the accumulated water under the opening.

[0161] The warning information may be sound and light information, or may be a push message sent to a user's personal terminal. This embodiment does not impose a rigid limit on the specific type of warning information, and only needs to meet the warning prompt requirements.

[0162] It can be seen that the present application realizes the detection of hidden dangers of water immersion and reduces the probability of water entering the battery box by setting the above-mentioned control method. Moreover, compared with the base solution in the related art, the detection device provided by the present application can meet the waterproof requirements of the opening without destroying the portability of the energy storage device and increasing the difficulty of arranging the energy storage device, thereby solving the technical problem of poor practicality of the energy storage device existing in the related art. At the same time, the above-mentioned control method executed in conjunction with the detection device can realize the detection of hidden dangers of water immersion that cannot be achieved by the base in the related art, so as to enhance the waterproof performance of the energy storage device and reduce the failure rate of the energy storage device. Thereby achieving the technical effect of optimizing the structure of the energy storage device, improving the safety and reliability of the energy storage device, and improving the user experience.

[0163] In some embodiments of the present invention, optionally, the warning information includes first warning information, and when the detection device detects that there is liquid below the opening, the step of controlling the energy storage device to issue the warning information includes:

[0164] When the detection device detects that there is liquid below the opening and there is no liquid inside the opening, the energy storage device is controlled to issue a first warning message;

[0165] Among them, the first warning information is used to indicate that the energy storage equipment is at risk of flooding.

[0166] In this embodiment, the detection device can not only detect whether there is liquid below the opening through electrical signals, but also detect whether there is liquid inside the opening through electrical signals. The warning information includes first warning information, which is used to remind the user that the energy storage device currently has a risk of flooding. When the user receives the first warning information, it proves that there is liquid below the energy storage device, but the liquid has not yet risen to the inside of the opening. The user can eliminate the hidden danger of flooding in time based on the first warning information.

[0167] On this basis, when the detection device detects that there is liquid below the opening, the steps of controlling the energy storage device to issue a warning message specifically include:

[0168] After the control detection device is turned on, if it can be determined based on the electrical signal fed back by the detection device that there is liquid below the opening and no liquid is inside the opening, it means that liquid has accumulated below the opening, but the accumulated liquid level has not yet risen to the height of the opening. The energy storage device is then controlled to issue a first warning message to remind the user that there is currently a risk of water immersion in the energy storage device, and the risk of water immersion needs to be eliminated in time to prevent the liquid level from further rising and entering the interior of the battery box through the opening.

[0169] It can be seen that by limiting the above control method, accurate detection of water flooding risk of energy storage equipment can be achieved, ensuring that users can eliminate water flooding risk in a timely manner through the first warning information, thereby reducing the probability of water flooding failure of energy storage equipment, and further achieving the technical effect of improving the intelligence level of energy storage equipment and reducing the failure rate of energy storage equipment.

[0170] like Figure 2 As shown, in some embodiments of the present invention, optionally, the detection device includes a first detection element, the first detection element is arranged below the opening, and the step of controlling the detection device to open includes:

[0171] Step 202, detecting a first resistance value of a first detection element;

[0172] Step 204 , based on the first resistance value being greater than or equal to the first threshold, determining that there is no liquid below the opening, and based on the first resistance value being less than the first threshold, determining that there is liquid below the opening.

[0173] In this embodiment, the detection device includes a first detection element. The detection device can determine whether there is liquid under the opening by detecting a first resistance value of the first detection element. The first resistance value of the first detection element will change when it contacts the liquid, and the first resistance value corresponds to the aforementioned electrical signal.

[0174] On this basis, the steps of controlling the detection device to start specifically include:

[0175] After the detection device is powered on, the first resistance value of the first detection element is detected in real time. When the detected first resistance value is greater than or equal to the first threshold value, it means that the first detection element has not been in contact with liquid. At this time, there is no liquid under the opening, the energy storage device is not at risk of flooding, and the battery box can operate normally. Correspondingly, when the detected first resistance value is less than the first threshold value, it means that the first detection element has been in contact with liquid. At this time, there is liquid under the opening, and the energy storage device is at risk of flooding. The energy storage device is then controlled to issue a first warning message or cooperate with the second detection element to issue a second warning message.

[0176] It can be seen that the above control method can monitor the liquid below the opening by monitoring the first resistance value of the first detection element, so that the energy storage device can respond in time when liquid appears below, thereby reducing the probability of water ingress failure in the energy storage device and achieving the technical effect of improving the intelligence level of the energy storage device.

[0177] Specifically, the first detection element includes a first metal wire and a second metal wire, and the first metal wire and the second metal wire are arranged side by side at the bottom of the bracket.

[0178] During operation, the resistance between the first metal wire and the second metal wire is detected. When the first metal wire and the second metal wire are not in contact with the liquid, the first metal wire and the second metal wire are insulated and have a relatively large resistance (greater than 1000KΩ). When the first metal wire and the second metal wire are in contact with the liquid below the opening, water is conducted between the first metal wire and the second metal wire, and the resistance becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ.

[0179] In some embodiments of the present invention, optionally, the warning information further includes second warning information, and when the detection device detects that there is liquid below the opening, the step of controlling the energy storage device to issue the warning information includes:

[0180] When the detection device detects that there is liquid below the opening and there is liquid inside the opening, the energy storage device is controlled to issue a second warning message;

[0181] The second warning information is used to indicate that a water immersion failure has occurred in the energy storage device.

[0182] In this embodiment, the warning information includes first warning information, and the second warning information is used to remind the user that there is a risk of water ingress to the energy storage device. When the user receives the second warning information, it proves that liquid has entered the opening and the energy storage device may experience a water ingress failure at any time.

[0183] On this basis, when the detection device detects that there is liquid below the opening, the steps of controlling the energy storage device to issue a warning message specifically include:

[0184] After the control detection device is turned on, if it can be determined based on the electrical signal fed back by the detection device that there is liquid below the opening, and there is also liquid on the inside of the opening, it means that the liquid has entered the opening. The energy storage device is then controlled to issue a second warning message to remind the user that there is currently a risk of water ingress to the energy storage device, and the risk of water immersion needs to be eliminated in time to avoid irreparable losses to the energy storage device.

[0185] It can be seen that by limiting the above control method, accurate detection of water ingress risk of energy storage equipment can be achieved, ensuring that users can eliminate water ingress risk in a timely manner through the second warning information, thereby reducing the probability of water ingress failure of the energy storage equipment, and further achieving the technical effect of improving the intelligence level of the energy storage equipment and reducing the failure rate of the energy storage equipment.

[0186] like Figure 3 As shown, in some embodiments of the present invention, optionally, the detection device further includes a second detection element, and the second detection element is disposed in the opening, and the step of controlling the detection device to open includes:

[0187] Step 302, detecting a second resistance value of a second detection element;

[0188] Step 304 , based on the second resistance value being greater than or equal to the second threshold, determining that there is no liquid in the opening, and based on the second resistance value being less than the second threshold, determining that there is liquid in the opening.

[0189] In this embodiment, the detection device includes a second detection element. The detection device can determine whether there is liquid inside the opening by detecting the second resistance value of the second detection element. The second resistance value of the second detection element will change when it comes into contact with the liquid, and the second resistance value corresponds to the aforementioned electrical signal.

[0190] On this basis, the steps of controlling the detection device to start specifically include:

[0191] After the detection device is powered on, the second resistance value of the first detection element is detected in real time. When the detected second resistance value is greater than or equal to the second threshold value, it means that the second detection element has not been in contact with liquid. At this time, there is no liquid inside the opening, and there is no risk of water entering the energy storage device. The battery box can work normally. Correspondingly, when the detected second resistance value is less than the second threshold value, it means that the second detection element has been in contact with liquid. At this time, there is liquid inside the opening, and there is a risk of water entering the energy storage device. The energy storage device is then controlled to issue a second warning message.

[0192] It can be seen that the above control method can monitor the liquid below the opening by monitoring the second resistance value of the second detection element, so that the energy storage device can respond in time when liquid appears inside the opening, thereby reducing the probability of water ingress failure in the energy storage device and achieving the technical effect of improving the intelligence level of the energy storage device.

[0193] Specifically, the second detection element includes a third metal wire and a fourth metal wire, and the third metal wire and the fourth metal wire are arranged side by side inside the opening.

[0194] During operation, the resistance between the third metal wire and the fourth metal wire is detected. When the third metal wire and the fourth metal wire are not in contact with liquid, the third metal wire and the fourth metal wire are insulated, and their resistance is relatively large (greater than 1000KΩ); when the third metal wire and the fourth metal wire are in contact with liquid inside the opening, water is conducted between the third metal wire and the fourth metal wire, and their resistance becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ.

[0195] In some embodiments of the present invention, optionally, after the step of controlling the energy storage device to issue a warning message, the control method further includes:

[0196] Control the battery box to cut off power and control the alarm device to work;

[0197] Wherein, the alarm device includes: an LED light and / or a buzzer.

[0198] In this embodiment, when the energy storage device issues a warning message based on the electrical signal fed back by the detection device, the energy storage device controls the battery box to cut off power and simultaneously starts the backup power supply to supply power to the alarm device on the energy storage device through the backup power supply and control the alarm device to start working. The alarm device is used to increase the probability of users knowing that a failure of the energy storage device has occurred, so that users can arrive in time and eliminate hidden dangers.

[0199] It can be seen that by limiting the above-mentioned control method, the energy storage device can be powered off in time when there is a risk of flooding or water ingress, so as to avoid irreparable losses of the energy storage device. At the same time, the alarm device can increase the probability of users knowing hidden dangers, reminding users to eliminate hidden dangers in time and restore the normal operation of the energy storage device, thereby achieving the technical effect of improving the automation and intelligence level of the energy storage device and improving the safety of the energy storage device.

[0200] like Figure 4 As shown, an embodiment of the present invention provides a control device 400 for an energy storage device, the energy storage device includes a battery box and a detection device, the bottom of the battery box includes an opening, and the control device includes: a first control module 402, which is used to control the detection device to turn on based on the detection device being connected to the battery box; a second control module 404, which is used to control the energy storage device to issue a warning message when the detection device detects that there is liquid under the opening.

[0201] The present invention provides a control device 400 for an energy storage device, which is used to control the operation of the energy storage device. The energy storage device stores a large amount of electric energy. After the energy storage device is connected to an electric device, the energy storage device can supply power to the electric device.

[0202] Specifically, the energy storage device includes a battery box. The battery box serves as an energy storage unit in the energy storage device. The energy storage capacity of the energy storage device can be increased by increasing the number of battery boxes. For example, when the energy demand is small, the user can carry a single battery box to meet the working needs of the applied electrical equipment. When the energy demand is large, multiple battery boxes can be carried and stacked together to power the applied electrical equipment through the multiple battery boxes. An opening is provided at the bottom of the battery box.

[0203] Among them, when the battery box is arranged at the bottom, the opening at the bottom of the battery box is close to the ground. At this time, the liquid accumulated on the ground may enter the box through the opening, causing the battery box to have short circuit, leakage and other faults, affecting the safety and reliability of the energy storage equipment.

[0204] In this regard, the present application also provides a detection device, which includes a first detection element. The detection device can detect whether there is liquid at the bottom of the waterproof plug through the first detection element.

[0205] On this basis, the control device of the battery box includes a first control module 402 and a second control module 404. After the battery box is assembled and the detection device is connected to the bottom battery box through an electrical connection, the first control module 402 controls the detection device to start, so that the detection device can perform detection at the opening of the bottom battery box. During the working process, the power supply work of the battery box and the detection work of the detection device are performed simultaneously.

[0206] After the control detection device is turned on, the second control module 404 can determine whether there is liquid under the opening based on the electrical signal fed back by the detection device. When it is determined that there is liquid under the opening based on the electrical signal, the second control module 404 controls the energy storage device to issue a warning message to remind the user that there is liquid under the opening and there is a risk of water immersion in the battery box at the bottom, so that the user can promptly check the risk of water immersion, such as moving the energy storage device to a dry place, or wiping off the accumulated water under the opening.

[0207] The warning information may be sound and light information, or may be a push message sent to a user's personal terminal. This embodiment does not impose a rigid limit on the specific type of warning information, and only needs to meet the warning prompt requirements.

[0208] It can be seen that the present application realizes the detection of hidden dangers of water immersion and reduces the probability of water entering the battery box by setting the above-mentioned control device. Moreover, compared with the base solution in the related art, the detection device provided by the present application can meet the waterproof requirements of the opening without destroying the portability of the energy storage device and increasing the difficulty of arranging the energy storage device, thereby solving the technical problem of poor practicality of the energy storage device existing in the related art. At the same time, the above-mentioned control device executed in conjunction with the detection device can realize the detection of hidden dangers of water immersion that the base in the related art cannot achieve, so as to enhance the waterproof performance of the energy storage device and reduce the failure rate of the energy storage device. Thereby achieving the technical effect of optimizing the structure of the energy storage device, improving the safety and reliability of the energy storage device, and improving the user experience.

To avoid repetition, it will not be repeated here.

[0215] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, an embodiment of the present invention provides an energy storage device 100, which includes: a battery box 110, the battery box 110 includes a box body 112 and a first connector 114, the bottom of the box body 112 includes an opening 1122, and the first connector 114 is arranged at the opening 1122; a sealing component 120, the sealing component 120 includes a waterproof plug 122 and a detection device 124, the detection device 124 is arranged at the waterproof plug 122, the waterproof plug 122 is detachably connected to the opening 1122, and when the waterproof plug 122 is installed in the opening 1122, the detection device 124 is electrically connected to the first connector 114; wherein the detection device 124 includes a first detection element 1242, and the detection device 124 is used to detect whether there is liquid at the bottom of the waterproof plug 122 through the first detection element 1242.

[0216] In this embodiment, an energy storage device 100 is proposed. A large amount of electric energy is stored in the energy storage device 100. After the energy storage device 100 is connected to an electric device, the energy storage device 100 can supply power to the electric device.

[0217] Specifically, the energy storage device 100 includes a battery box 110. The battery box 110 serves as an energy storage unit in the energy storage device 100. The energy storage capacity of the energy storage device 100 can be increased by increasing the number of battery boxes 110. For example, when the power demand is small, the user can carry a single battery box 110 to meet the working needs of the applied electrical equipment. When the power demand is large, multiple battery boxes 110 can be carried and stacked together to power the corresponding electrical equipment through the multiple battery boxes 110.

[0218] The battery box 110 includes a box body 112 and a first connector 114. The box body 112 forms the outer surface of the battery box 110. The box body 112 can provide shielding and protection for the internal structure of the battery box 110 to reduce the failure rate of the battery box 110. The battery box 110 is provided with an opening 1122 at the bottom, and the first connector 114 is provided at the opening 1122. Correspondingly, a second connector is also provided at the top of the box body 112, and the second connector is adapted to the first connector 114.

[0219] When multiple battery boxes 110 need to be stacked together, the battery box 110 located on the top is plugged together with the second connector pair of the battery box 110 located on the bottom through the first connector 114 to complete the electrical connection between two adjacent battery boxes 110. Similarly, the energy storage capacity of the energy storage device 100 can be increased by increasing the number of stacked battery boxes 110.

[0220] Among them, when the battery box 110 is arranged at the bottom, the opening 1122 at the bottom of the battery box 110 is close to the ground. At this time, the liquid accumulated on the ground may enter the box body 112 through the opening 1122, causing the battery box 110 to have short circuit, leakage and other faults, affecting the safety and reliability of the energy storage device 100.

[0221] In this regard, the present application also provides a sealing component 120, which includes a waterproof plug 122. The waterproof plug 122 can be detachably arranged at the opening 1122. When the waterproof plug 122 is installed at the opening 1122, the waterproof plug 122 can seal the opening 1122 to reduce the probability of liquid entering the opening 1122, thereby realizing a waterproof design of the battery box 110 at the bottom.

[0222] Among them, the waterproof plug 122 can prevent liquid that approaches the opening 1122 for a short time from entering the opening 1122 to a certain extent. However, when liquid accumulates under the waterproof plug 122 for a long time and there is a risk of the waterproof plug 122 being soaked by the liquid, the hidden danger of failure of the battery box 110 cannot be eliminated by the waterproof plug 122 alone.

[0223] In this regard, the present application also provides a detection device 124 on the waterproof plug 122, and the detection device 124 includes a first detection element 1242. The detection device 124 can detect whether there is liquid at the bottom of the waterproof plug 122 through the first detection element 1242. When the detection device 124 determines that there is liquid at the bottom of the waterproof plug 122, it can control the battery box 110 to cut off power or issue a water immersion alarm in time to avoid irreversible failure of the energy storage device 100, and at the same time remind the user to move the energy storage device 100 in time to eliminate the risk of water immersion.

[0224] It can be seen that the present application reduces the probability of liquid entering the opening 1122 by setting the waterproof plug 122, and at the same time realizes the detection of water immersion hazards by setting the detection device 124, further reducing the probability of water entering the battery box 110. In addition, compared with the base solution in the related art, the waterproof plug 122 provided by the present application is smaller in volume and weight, and can meet the waterproof requirements of the opening 1122 without destroying the portability of the energy storage device 100 and increasing the difficulty of arranging the energy storage device 100, thereby solving the technical problem of poor practicality of the energy storage device 100 existing in the related art. At the same time, by setting the detection device 124, the present application can realize the detection of water immersion hazards that cannot be realized by the base in the related art, so as to enhance the waterproof performance of the energy storage device 100 and reduce the failure rate of the energy storage device 100. Then, the technical effect of optimizing the structure of the energy storage device 100, improving the safety and reliability of the energy storage device 100, and improving the user experience is achieved.

[0225] like Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments of the present invention, optionally, the waterproof plug 122 includes a bracket 1222, and when the waterproof plug 122 is installed on the opening 1122, the bracket 1222 blocks the opening 1122, and the detection device 124 also includes: a detection unit 1244, the detection unit 1244 is arranged on the side of the bracket 1222 facing the battery box 110, and when the waterproof plug 122 is installed on the opening 1122, the detection unit 1244 is electrically connected to the first connector 114, and the detection unit 1244 includes a first interface 12442; wherein, the first detection element 1242 is arranged on the side of the waterproof plug 122 facing away from the battery box 110, and the first detection element 1242 is connected to the first interface 12442.

[0226] In this embodiment, the waterproof plug 122 includes a bracket 1222 , the shape of the bracket 1222 is adapted to the shape of the opening 1122 , and when the waterproof component is installed in the opening 1122 , the bracket 1222 is partially embedded in the opening 1122 .

[0227] On this basis, the detection device 124 also includes a detection unit 1244, which is disposed on a bracket 1222. The bracket 1222 is used to position and support the detection unit 1244. Specifically, the detection unit 1244 is disposed on a side of the bracket 1222 facing the battery box 110. The bracket 1222 can also act as a water barrier to prevent the detection unit 1244 from being damaged due to contact with liquid.

[0228] Among them, the first detection element 1242 is arranged below the bracket 1222, and the first detection element 1242 is electrically connected to the detection unit 1244 through a line connection. After the assembly of the sealing component 120 is completed, the detection unit 1244 is connected to the first connector 114, and the battery box 110 can supply power to the detection unit 1244 and the first detection element 1242 through the first connector 114, so that the first detection element 1242 can detect whether there is liquid below the bracket 1222 on the outside of the bracket 1222.

[0229] It can be seen that by setting up the bracket 1222, waterproof protection can be provided for the inner detection unit 1244 to prevent liquid from corroding the detection unit 1244, thereby ensuring that the detection result of the detection unit 1244 is accurate. At the same time, the bracket 1222 can position the first detection element 1242 below the battery box 110, so that the first detection element 1242 can be close to the ground, thereby improving the accuracy and timeliness of water immersion detection, and achieving the technical effect of improving the safety and reliability of the energy storage device 100 and reducing the failure rate of the energy storage device 100.

[0230] like Figure 8 , Fig. 9 and Fig.14 As shown, in some embodiments of the present invention, optionally, the first detection element 1242 includes: a first metal wire 12422; a second metal wire 12424, the first metal wire 12422 and the second metal wire 12424 are arranged side by side on the side of the bracket 1222 facing away from the battery box 110, and when the first metal wire 12422 and the second metal wire 12424 contact the liquid, the detection unit 1244 generates a first electrical signal.

[0231] In this embodiment, the first detection element 1242 includes a first metal wire 12422 and a second metal wire 12424, which are arranged side by side at the bottom of the bracket 1222. After the sealing component 120 is assembled, the first metal wire 12422 and the second metal wire 12424 are located below the opening 1122 to ensure that the first detection element 1242 can detect the risk of water immersion before the water level of the liquid rises to the opening 1122.

[0232] Specifically, the first metal wire 12422 and the second metal wire 12424 are both electrically connected to the first interface 12442 of the detection unit 1244 .

[0233] During operation, the detection unit 1244 detects the resistance 11448 between the first metal wire 12422 and the second metal wire 12424. When the first metal wire 12422 and the second metal wire 12424 are not in contact with the liquid, the first metal wire 12422 and the second metal wire 12424 are insulated, and their resistance 11448 is relatively large (greater than 1000KΩ); when the first metal wire 12422 and the second metal wire 12424 are in contact with the liquid below the opening 1122, water is conducted between the first metal wire 12422 and the second metal wire 12424, and their resistance 11448 becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ, and the information of the reduced resistance is transmitted to the detection unit 1244 as a first electrical signal.

[0234] Correspondingly, when the detection unit 1244 does not receive the first electrical signal, the detection unit 1244 outputs the first low level to the first connector 114, and the control circuit 130 in the battery box 110 can determine that the energy storage device 100 currently does not have a risk of flooding through the first low level output by the detection unit 1244, and control the energy storage device 100 to work normally. Conversely, when the detection unit 1244 receives the first electrical signal, the detection unit 1244 outputs the first high level to the first connector 114, and the control circuit 130 in the battery box 110 can determine that the energy storage device 100 currently has a risk of flooding through the first high level output by the detection unit 1244, so that the control circuit 130 can determine whether to control the energy storage device 100 to be powered off according to the risk of flooding, and determine whether an alarm needs to be issued.

[0235] It can be seen that the present application realizes the water immersion detection function below the opening 1122 by setting the first metal wire 12422 and the second metal wire 12424, so that the energy storage device 100 can detect the water immersion risk in time according to the first electrical signal and reduce the loss caused by the water immersion risk, thereby achieving the technical effect of improving the safety and reliability of the energy storage device 100 and improving the intelligence level of the energy storage device 100.

[0236] like Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, in some embodiments of the present invention, optionally, the waterproof plug 122 also includes a waterproof ring 1224. When the waterproof plug 122 is installed in the opening 1122, the waterproof ring 1224 is located between the opening 1122 and the bracket 1222. The detection unit 1244 also includes a second interface 12444. The detection device 124 also includes: a second detection element 1246. The second detection element 1246 is connected to the second interface 12444, and the second detection element 1246 is arranged in the waterproof ring 1224. The detection device 124 is used to detect whether there is liquid in the opening 1122 through the second detection element 1246.

[0237] In this embodiment, a waterproof ring 1224 is sleeved on the bracket 1222. Specifically, a ring-shaped convex rib is set on the top of the bracket 1222, and the waterproof ring 1224 is sleeved around the convex rib. After the sealing component 120 is assembled, the waterproof ring 1224 is located between the bracket 1222 and the opening 1122. The waterproof ring 1224 can seal the bracket 1222 and the opening 1122 by filling the gap between the opening 1122 and the bracket 1222, so as to reduce the probability of liquid entering the inner side of the opening 1122.

[0238] On this basis, the detection device 124 further includes a second detection element 1246, which is disposed on the waterproof ring 1224, and the second detection element 1246 is connected to the second interface 12444 on the detection unit 1244 through a line, so that the second detection element 1246 is electrically connected to the detection unit 1244. After the sealing component 120 is assembled, the detection unit 1244 is connected to the first connector 114, and the battery box 110 can supply power to the detection unit 1244 and the second detection element 1246 through the first connector 114, so that the second detection element 1246 can detect whether liquid enters the opening 1122 from the inside of the opening 1122.

[0239] It can be seen that by arranging the second detection element 1246 on the waterproof ring 1224, the detection device 124 can detect whether liquid has entered the inside of the opening 1122, so as to accurately control the water inflow of the opening 1122, so as to timely control the energy storage device 100 to cut off the power and issue an alarm when it is determined that water has entered the inside of the opening 1122, thereby reducing the failure rate of the energy storage device 100 and the water inflow loss, thereby achieving the technical effect of improving the safety and reliability of the energy storage device 100.

[0240] like Fig.10 , Fig.11 , Fig.12 and Fig.14 As shown, in some embodiments of the present invention, optionally, the second detection element 1246 includes: a third metal wire 12462; a fourth metal wire 12464, the third metal wire 12462 and the fourth metal wire 12464 are arranged side by side on the peripheral side of the waterproof ring 1224, and when the third metal wire 12462 and the fourth metal wire 12464 are in contact with liquid, the detection unit 1244 generates a second electrical signal.

[0241] In this embodiment, the first detection element 1242 includes a third metal wire 12462 and a fourth metal wire 12464, and the third metal wire 12462 and the fourth metal wire 12464 are arranged side by side at the root of the waterproof ring 1224. After the sealing component 120 is assembled, the third metal wire 12462 and the fourth metal wire 12464 are located on the inner side of the opening 1122 and close to the lower end of the opening 1122 to ensure that the second detection element 1246 can detect the risk of water ingress in the first time when water enters the opening 1122.

[0242] Specifically, the third metal line 12462 and the fourth metal line 12464 are both electrically connected to the second interface 12444 of the detection unit 1244 .

[0243] During operation, the detection unit 1244 detects the resistance 11448 between the third metal wire 12462 and the fourth metal wire 12464. When the third metal wire 12462 and the fourth metal wire 12464 are not in contact with liquid, the third metal wire 12462 and the fourth metal wire 12464 are insulated, and their resistance 11448 is relatively large (greater than 1000KΩ); when the third metal wire 12462 and the fourth metal wire 12464 are in contact with liquid on the inner side of the opening 1122, water is conducted between the third metal wire 12462 and the fourth metal wire 12464, and their resistance 11448 becomes smaller (less than 1000KΩ), which can usually be reduced to below 100KΩ, and the information of the reduced resistance is transmitted to the detection unit 1244 as a second electrical signal.

[0244] Correspondingly, when the detection unit 1244 does not receive the second electrical signal, the detection unit 1244 outputs the second low level to the first connector 114, and the control circuit 130 in the battery box 110 can determine that the opening 1122 has not been flooded by the second low level output by the detection unit 1244, and control the energy storage device 100 to work normally. Conversely, when the detection unit 1244 receives the second electrical signal, the detection unit 1244 outputs the second high level to the first connector 114, and the control circuit 130 in the battery box 110 can determine that the opening 1122 has been flooded by the second high level output by the detection unit 1244, so that the control circuit 130 can control the energy storage device 100 to be powered off according to the water ingress risk, and control the energy storage device 100 to issue an alarm.

[0245] It can be seen that the present application realizes water ingress detection inside the opening 1122 by setting the third metal wire 12462 and the fourth metal wire 12464, so that the energy storage device 100 can timely detect the risk of water ingress into the opening 1122 according to the second electrical signal and reduce the loss caused by the risk of water ingress, thereby achieving the technical effect of improving the safety and reliability of the energy storage device 100 and improving the intelligence level of the energy storage device 100.

[0246] Specifically, the first detection element 1242 and the second detection element 1246 work together. When the control circuit 130 only receives the first low level and the second low level, it means that there is no liquid accumulated under the opening 1122 and no liquid enters the inside of the opening 1122. At this time, the working environment of the energy storage device 100 is relatively safe, and the energy storage device 100 can be controlled to work normally.

[0247] When the control circuit 130 receives the first high level and the second low level, it indicates that liquid is accumulated under the opening 1122 and there is a risk of flooding, but the liquid level has not risen to the opening 1122. At this time, the energy storage device 100 can be controlled to work normally, and a flood alarm can be issued to the user at the same time to remind the user to eliminate the risk of flooding in time, such as wiping the liquid under the energy storage device 100 or moving the energy storage device 100 to a dry place.

[0248] When the control circuit 130 receives the first high level and the second high level at the same time, it indicates that the liquid level has risen to the opening 1122. The control circuit 130 then controls the energy storage device 100 to cut off power and sends a water ingress alarm to the user to reduce water ingress losses and remind the user to eliminate the water ingress fault in time.

[0249] It can be seen that by providing the first detection element 1242 and the second detection element 1246 that work together, the intelligence and automation of the energy storage device 100 are improved, and the safety and reliability of the energy storage device 100 are improved.

[0250] like Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, in some embodiments of the present invention, optionally, the first connector 114 includes: a cover body 1142, the cover body 1142 covers the opening 1122 on the inner side of the box body 112; a first terminal 1144, which is arranged on the side of the cover body 1142 facing the opening 1122, and the first terminal 1144 can be electrically connected to the detection unit 1244.

[0251] In this embodiment, the first connector 114 includes a cover 1142 and a first terminal 1144 .

[0252] The cover 1142 is installed inside the box 112. After assembly, the cover 1142 is snapped into the opening 1122 at the bottom of the box 112 on the inside of the box 112. The first terminal 1144 is installed in the cover 1142. The cover 1142 can provide positioning and support for the first terminal 1144. After assembly, the first terminal 1144 is aligned with the opening 1122. When the sealing component 120 is assembled to the opening 1122, the first terminal 1144 is electrically connected to the detection device 124 on the sealing component 120, so that the battery box 110 can power the detection device 124, so as to realize water immersion risk detection and water ingress risk detection of the opening 1122.

[0253] On the one hand, the cover 1142 can play a role in positioning the first terminal 1144, so that the first terminal 1144 can be accurately positioned at a predetermined position, thereby ensuring the connection reliability between the first terminal 1144 and the detection device 124. On the other hand, the cover 1142 can serve as the last waterproof barrier of the battery box 110. When liquid enters the inner side of the cover 1142 through the opening 1122, the cover 1142 can block the liquid and reduce the probability of the liquid diffusing to the outer side of the cover 1142, thereby improving the waterproof performance of the energy storage device 100 and achieving the technical effect of improving the safety and reliability of the energy storage device 100.

[0254] like Fig.13 As shown, in some embodiments of the present invention, optionally, the energy storage device 100 further includes: a control circuit 130, the control circuit 130 is arranged in the box 112, and the control circuit 130 includes a first power supply end ( Fig.13 VCC shown in the figure) and the first ground terminal ( Fig.13 GND shown in the figure); wherein the first terminal 1144 includes a first connection terminal 11442, a second connection terminal 11444 and a first signal terminal 11446, the first connection terminal 11442 is used to connect to the first power supply terminal, the second connection terminal 11444 is used to connect to the first ground terminal, and the first signal terminal 11446 is used to connect to the first ground terminal through a resistor 11448.

[0255] In this embodiment, a control circuit 130 is disposed in the battery box 110 , and the control circuit 130 is connected to the battery in the battery box 110 to control the charging and discharging process of the battery.

[0256] On this basis, the control circuit 130 includes a first power supply terminal and a first ground terminal, and the first terminal 1144 includes a first connection terminal 11442, a second connection terminal 11444 and a first signal terminal 11446. The first connection terminal 11442 is connected to the first power supply terminal through a line, and the second connection terminal 11444 is connected to the first ground terminal through a line.
