[0040] The specific embodiments of the present application will be described below in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the description of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0041] With reference to Figure 1 , one embodiment of the present application provides a charging system 1, the charging system 1 includes a charger 100, the charger 100 includes at least one charger charging interface 110, the charger charging interface 110 is detachably connected to a battery pack, the charger 100 controls the output power supply power to the charger charging interface 110.

[0042] The charging system 1 further includes a charging cabinet 200. The charging cabinet 200 and the charger 100 are two independent devices. The charging cabinet 200 includes a charging cabinet main body 210 and a power input cable 220, and the charging cabinet 200 is connected with the charger 100 through the power input cable 220. With reference to Figure 2 and Figure 3The charging cabinet 200 includes at least one charging cabinet charging interface 211 (four are shown in the figure, but the present application is not limited thereto), and the charging cabinet charging interface 211 is detachably connected to a battery pack. When the charging cabinet 200 is connected to the charger 100, the power input cable 220 is connected to the charger charging interface 110 of the charger 100, the charging cabinet 200 obtains power supply power from the charger charging interface 110, and outputs the power supply power to at least one charging cabinet charging interface 211 to charge the battery pack connected to the at least one charging cabinet charging interface 211.

[0043] In the embodiment, the charger charging interface 110 can be connected to a battery pack or the power input cable 220 of the charging cabinet 200. Specifically, when the user only needs to charge one or two battery packs, the battery pack is plugged into the charger charging interface 110, and the charger 100 can control the output of the power supply power to the charger charging interface 110 where the battery pack is located to charge the corresponding battery pack. When the user needs to charge multiple battery packs, due to the limitation of the number of charger charging interfaces on a single charger device, the user can only replace the battery pack in time to complete the charging of all battery packs, which will bring great inconvenience to the user in the night charging scene, and cannot meet the user's demand of charging a night at a time. Therefore, the charging cabinet 200 with an expanded charging interface can be selected. When the user connects the charging cabinet 200 to the charger charging interface 110 of the charger 100, the charger 100 can also control the output of the power supply power to the charger charging interface 110 connected to the charging cabinet 200, so that the charging cabinet 200 uses the power supply power to charge the battery pack connected to the charging cabinet charging interface 211 in the charging cabinet 200.

[0044] That is, the charger 100 can charge the battery pack or provide power supply power to the charging cabinet 200 to charge the battery pack connected to the charging cabinet charging interface 211 in the charging cabinet 200, which is compatible with various charging needs and scenarios. Moreover, even if the user has the need for expansion charging, such as the need to charge multiple battery packs at a night, the user only needs to purchase a charging cabinet, without the need to purchase a separate power supply device matching the charging cabinet. The user can directly use the existing charger 100 to power the charging cabinet to achieve charging of multiple battery packs, which not only effectively improves the utilization efficiency of the charger 100, but also reduces the user's use cost.

[0045] Preferably, the battery pack is an electric tool battery pack, and the electric tool includes garden tools, household tools, professional tools, etc. The type of battery pack connected to the charger charging interface 110 can be the same as or different from the type of battery pack connected to the charging cabinet charging interface 211. The type of battery pack refers to at least one parameter of the battery pack being different, such as one or more of the parameters of size, type of battery cell, capacity, rated voltage, etc.

[0046] In an embodiment, the charger charging interface 110 and the charging cabinet charging interface 211 can be the same or different. Wherein the same interface means that at least the connection structure of the interface is the same. In the embodiment, the charger 100 and the charging cabinet 200 are preferably charging devices of the same battery pack voltage platform, and need to match the same series of battery packs as much as possible, so the corresponding charger charging interface 110 and the charging cabinet charging interface 211 are at least the same in connection structure.

[0047] In an embodiment, the charging cabinet 200 further comprises a first housing 240, an upper cover 250 and a power supply device 260, the first housing 240 is configured as an open box type, as shown in Figure 3 The opening of the first housing 240 is upward, and the upper cover 250 covers the opening when it is covered, and forms a receiving cavity with the first housing 240 to accommodate the power supply device 260. Wherein the power supply device 260 is at least partially contained in the first housing 240, and is optionally arranged at the middle position of the first housing, for outputting power supply power to each charging cabinet charging interface 211.

[0048] Wherein the charging cabinet charging interface 211 is arranged on the single and / or double side of the power supply device 260, and the charging cabinet charging interface 211 can be provided with a first matching structure and a second matching structure to respectively plug different types of battery packs. The charging cabinet charging interface 211 is provided with an unlocking button and an indicator lamp corresponding to the respective position of the power supply device 260, the unlocking button is used to remove the battery pack connected to the charging cabinet charging interface 211 when pressed, and the indicator lamp is used to indicate the charging state of the battery pack by the charging cabinet 200. The battery pack connected to the charging cabinet charging interface 211 includes at least two different types of battery packs. Wherein the different types of battery packs means that at least one parameter of the battery pack is different, for example, one or more of the size, cell type, capacity, such as two battery packs with the same cell type and capacity but different sizes, or two battery packs with the same cell type and size but different capacities, or two battery packs with the same size and capacity but different cell types.

[0049] In an embodiment, the charging cabinet 200 further comprises a pull rod 270 (not shown in the figure) for facilitating the user to carry the charging cabinet. Specifically, a recess is arranged on one side of the first housing 240, and the pull rod 270 is at least partially accommodated in the recess. Wherein the pull rod 270 can be at least one of a foldable pull rod and a non-foldable pull rod. When the foldable pull rod is unfolded, it at least partially extends out of the recess, and when the foldable pull rod is folded, it can be accommodated in the recess to reduce the occupied position when not in use.

[0050] In an embodiment, the charging cabinet 200 further comprises a plurality of rollers 280 (not shown in the figure) supported at the bottom of the charging cabinet 200, for cooperating with the pull rod 270 to transport the charging cabinet 200. When there is a need to transport the charging cabinet 200, the pull rod 270 is pushed and pulled to push the rollers 280 at the bottom of the charging cabinet 200 to roll, thereby achieving the need to conveniently transport the charging cabinet 270.

[0051] In an embodiment, the first end of the power input cable 220 is connected to the charging cabinet body 210, and the second end is detachably connected to the charger charging interface 110.

[0052] Specifically, the first end of the power input cable 220 is fixedly connected or detachably connected to the charging cabinet body 210, for example, the first end is fixed in the charging cabinet body 210 by riveting, or the first end is directly fixed to the charging cabinet body 210 by an integral injection molding piece, or the first end and the charging cabinet body connection are respectively detachably connected in a male-female head matching manner. The specific connection mode is not specifically limited here and can be designed based on actual needs.

[0053] The second end of the power input cable 220 is detachably connected to the charger charging interface 110. The connection structure of the second end of the power input cable 220 cooperates with the structure of the charger charging interface 110 to match the connection. In an embodiment, the second end is in the form of an adapter, and the connection structure of the adapter is the same as the connection structure of the battery pack that can be connected to the charger charging interface. Therefore, the charging cabinet 200 can directly access the charger charging interface 110 of the charger 100 through the second end of the power input cable 220 to obtain power supply from the charger 100, thereby improving the consistency of the system and the convenience of user use.

[0054] In an embodiment, as shown in Figure 4A and 4B The charger charging interface 110 comprises a charger positive terminal 112, a charger negative terminal 114, and a charger communication terminal 116; the second end of the power input cable 220 comprises a charging cabinet positive terminal 222, a charging cabinet negative terminal 224, and a charging cabinet communication terminal 226; when the second end of the power input cable 220 is connected to the charger charging interface 110, the charging cabinet positive terminal 112 is connected to the charger positive terminal 222, the charging cabinet negative terminal 114 is connected to the charger negative terminal 224, and the charging cabinet communication terminal 114 is connected to the charger communication terminal 224.

[0055] The charger positive terminal 112, the charger negative terminal 114, the charging cabinet positive terminal 222, and the charging cabinet negative terminal 224 are power terminals, used for transmitting power between the charger 100 and the charging cabinet 200. The charger communication terminal 116 and the charging cabinet communication terminal 226 are communication terminals, used for communication between the charger 100 and the charging cabinet 200. Of course, the charger charging interface 110 and / or the second end can also be provided with other communication terminals to be compatible with different connection devices, which are not limited here.

[0056] In an embodiment, the charger 100 includes a first communication protocol. The charger 100 communicates with the battery pack connected to the charger charging interface 110 in the first communication protocol, and controls the output of power to the corresponding charger charging interface 110 according to the communication information. The charger 100 communicates with the charging cabinet 200 in the first communication protocol, and controls the output of power to the corresponding charger charging interface 110 according to the communication information.

[0057] Specifically, the charger 100 stores at least a first communication protocol, and the battery pack supports at least using the first communication protocol to realize communication between the charger 100 and the battery pack. The charger 100 controls the output of power to the charger charging interface 110 where the battery pack is located based on the communication information of both, to control the charging of the battery pack. Since the battery pack and the charging cabinet 200 are connected to the charger by connecting to the charger charging interface 110, the charger can use the same first communication protocol to communicate with the devices connected from the charger charging interface 110, that is, also communicate with the charging cabinet through the first communication protocol. Further, the charger 100 controls the output of power to the corresponding charger charging interface 110 based on the communication information, to power the charging cabinet 200.

[0058] It can be understood that the charger will not power all devices connected to the charger charging interface 110. If the connected device does not match the charger, or exceeds the power supply capability of the charger, the charger will not output power to the charger charging interface 110. The charger will not output power to the battery pack to be charged within the allowed charging range. Therefore, if the charging cabinet 200 wants to obtain power from the charger charging interface 110, it can communicate with the charger as a battery pack and with the needs of the battery pack. In an implementable way, the charging cabinet 200 can at least communicate with the charger 100 in accordance with the first communication protocol supported by the battery pack, so as to ensure as much as possible to obtain power from the charger.

[0059] Of course, the way the charging cabinet 200 obtains power from the charger 100 is not limited to this, and in another embodiment, the charger can also be interconnected with the charger in various ways such as hardware circuit detection, hardware circuit detection combined with communication, etc. to obtain power supply power.

[0060] In this embodiment, the charger communicates with the charging cabinet by using the first communication protocol for communication with the battery pack, i.e. the charging cabinet can communicate with the charger in the manner of the battery pack, i.e. simplifying the communication logic of the charger and the charging cabinet, and effectively avoiding the case that the charging cabinet is judged by the charger as a device that cannot be powered, ensuring that the battery cabinet can obtain power supply power from the charger, and improving the system stability.

[0061] In an embodiment, the charger 100 also includes a second communication protocol, and the charger 100 communicates with the battery pack matched with the charger charging interface 110 in the second communication protocol, and controls the output of the charging power to the corresponding charger charging interface 110 according to the communication information.

[0062] In order to match various types of battery packs, or in order to match battery packs compatible with multiple communication protocols, the charger can also store multiple communication protocols. That is, the charger also stores a second communication protocol that can communicate with the battery pack, and controls the output of the power supply power according to the communication information. Among them, the second communication protocol is different from the first communication protocol.

[0063] For example, the battery pack is compatible with the first communication protocol and the second communication protocol, and the charger is correspondingly compatible with the first communication protocol and the second communication protocol to communicate with the battery pack using at least one of the communication protocols. The advantage of this design is that when the charger fails to communicate with the battery pack through either the first communication protocol or the second communication protocol, the other communication protocol can still be used for communication to avoid the use of a single communication method to limit the use of the charger or the battery pack, affecting the user experience.

[0064] Of course, the charger 100 can also choose to use the first communication protocol and the second communication protocol to communicate with the charging cabinet. Generally, the communication terminal is usually used for communication in a certain communication protocol, and when multiple communication protocols need to be compatible, multiple groups of communication terminals need to be set, which is more complex in structure to some extent. Therefore, if the charging cabinet 200 wants to be compatible with two communication protocols, the charging cabinet needs to be set with communication terminals that match the first communication protocol and the second communication protocol, respectively. In this embodiment, only the first communication protocol is used to communicate with the charger, which not only realizes the communication and control requirements, but also simplifies the design of the charging cabinet and reduces the manufacturing cost.

[0065] In an embodiment, as Figure 5As shown, the charging cabinet 200 includes a first management module 230, and the charger includes a master control module 130; the first management module 230 sends power consumption parameter information to the master control module 130, wherein the power consumption parameter information represents the power consumption demand of the charging cabinet 200; correspondingly, the master control module 130 controls the output of power supply power to the charging interface 110 of the charger connected to the charging cabinet 200 in response to the power consumption parameter information.

[0066] When the charging cabinet 200 and the charger 100 are in a connected state, the first management module 230 is correspondingly connected to the master control module 130 and transmits communication information through the charger communication terminal 116 and the charging cabinet communication terminal 226. The first management module 230 obtains the power consumption demand of the charging cabinet 200, generates power consumption parameter information, and sends the power consumption parameter information to the master control module 130 through the above-mentioned communication terminal to obtain the required power from the charger 100. Correspondingly, the master control module 130 of the charger 100 receives the power consumption parameter information of the charging cabinet 200, matches the power supply power according to the power consumption parameter information and outputs to the charging interface 110 of the charger to supply power to the charging cabinet 200, thereby meeting the power consumption demand of the charging cabinet 200.

[0067] In this embodiment, the charging cabinet obtains the power supply power matched with the actual power consumption demand of the charging cabinet from the charger through the simplified way of active request, which not only improves the efficiency of communication between the two parties, but also greatly avoids unnecessary power loss and improves the power utilization rate.

[0068] In an embodiment, the power consumption parameter information at least includes the battery pack charging demand parameter of the battery pack matched with the charging interface 211 of the charging cabinet.

[0069] It can be understood that the main function of the charging cabinet 200 is to charge the accessed battery pack, and therefore the main power consumption demand mainly comes from the charging demand of the battery pack. Therefore, the power consumption parameter information of the charging cabinet 200 at least includes the charging demand parameter of the battery pack matched with at least one charging interface 211 of the charging cabinet. The charging demand parameter of the battery pack includes but is not limited to the charging voltage, charging current, charging power, charging temperature range, charging protection threshold and the like required by the battery pack.

[0070] Of course, the power consumption parameter information can also include other demand parameters, that is, the charging cabinet 200 can also have other power consumption demands, such as power supply for the first management module 230 and related control circuit, power supply for other functional modules such as heating module, cooling module, wireless communication module, locking module and the like. The power supply mode of other power consumption demands is not limited here.

[0071] In an embodiment, the first management module 230 is further configured to: acquire the battery pack parameters at the at least one charging cabinet charging interface 211, determine the battery pack with the highest charging priority according to the battery pack parameters, and determine the battery pack charging demand parameters according to the battery pack parameters of the battery pack with the highest charging priority.

[0072] Since one charging interface 110 of the charger 100 is usually connected with only one battery pack, the charging power of the charger 100 can meet the charging demand of the matched battery pack and make the battery pack in the best charging state, such as fast charging rate and best charging state, in general. In the embodiment, the charging cabinet 200 can also be connected to the charging interface 110 of the charger 100, which is an independent device capable of charging multiple battery packs.

[0073] When the charging interface 110 of the charger 100 is connected to the charging cabinet 200 and multiple battery packs are connected to the charging cabinet 200, it is equivalent to connecting multiple battery packs to one charging interface 110 of the charger 100. In order to improve the charging efficiency and avoid overload, one or a few battery packs are usually charged first, and then other battery packs are charged after the battery packs are fully charged. Taking the case of charging one battery pack at a time as an example, the power consumption parameter information of the charging cabinet 200 is mainly the charging demand parameters of the one battery pack currently to be charged.

[0074] When multiple battery packs are connected to the charging cabinet 200 at the same time, it is necessary to sort the multiple battery packs according to the battery pack parameters to determine which battery pack or battery packs are currently being charged. The battery pack parameters include at least the parameter range of the battery pack allowed to be charged, the remaining power of the battery pack, the order of the position of the battery pack, and other battery pack parameters. In one embodiment, the first management module 230 acquires the battery pack parameters of the multiple battery packs connected to the multiple charging cabinet charging interfaces 211, filters out the battery packs allowed to be charged according to the battery pack parameters, determines one or several battery packs with the highest charging priority according to the order of the position of the battery packs, and determines the battery pack parameters of the one or several battery packs as the battery pack charging demand parameters as the power consumption parameter information of the charging cabinet 200 to send a request to the charger 100.

[0075] In the embodiment, the battery pack parameters of the battery pack with the highest charging priority are selected as the power consumption parameter information, which can improve the charging efficiency, fully charge the battery pack in the shortest time, and match the power supply request sent by the charging cabinet 200 with the actual power consumption demand of the charging cabinet 200 to a great extent, effectively avoiding the waste of power.

[0076] In an embodiment, the charging cabinet 200 comprises a first management module 230, and the charging cabinet 200 further comprises a first power supply circuit 231 and a second power supply circuit 232. The battery pack connected to the charging cabinet charging interface 211 is connected to the first power supply circuit 231 to supply power to the first management module 230, and the charger 100 is connected to the second power supply circuit to supply power to the first management module 230. When the first management module 230 is started, the first power supply circuit 231 is first started to supply power to the first management module 230; when the first management module 230 obtains power supply from the charger 100, the second power supply circuit 232 is switched to supply power.

[0077] In the process, the first management module 230 is first powered by the battery pack connected to the charging cabinet charging interface 211.

[0078] It can be understood that the charging cabinet 200 itself is a passive device, and its power sources include the external charger 100 and the battery pack connected to the charging cabinet charging interface 211. Therefore, the charging cabinet 200 is provided with a first power supply circuit and a second power supply circuit for the first management module 230 to connect the battery pack at the charging cabinet charging interface and the charger to obtain power supply. It can be understood that when the charging cabinet 200 is just started and has not obtained power from the charger 100, since the charging cabinet 200 has no other power supply source, the power of the battery pack connected to the charging cabinet charging interface 211 can be temporarily used for power supply. It can be understood that the battery pack is mainly inserted into the charging cabinet 200 to be charged for user use, and power waste should be avoided as much as possible. Therefore, the actual power supply of the charging cabinet 200 should be preferably obtained from the charger 100. Therefore, once the first management module 230 detects that the charging cabinet 200 obtains power supply from the charger 100, the charger connected by the second power supply circuit will be switched to supply power, so as to avoid further loss of battery pack power.

[0079] In an embodiment, the charging cabinet body is further provided with a trigger key 240. The trigger key 240 is turned on in response to external triggering, that is, the power supply circuit of the first management module 230 by the battery pack is turned on, so that the first management module 230 is started and enters the working state from the closed state. When the first management module 230 is powered, an access signal needs to be sent to the connected charger in time to inform the charger 100 of the access state as soon as possible to obtain power supply from the charger 100.

[0080] For example, when the power of the battery pack connected to the charging interface 211 of the charging cabinet temporarily powers the first management module 230, the first management module 230 first sends an access signal to the charger 100 to inform the charger. The charger responds to the access signal and establishes communication with the first management module 230. Further, the charger 100 matches the power supply power according to the communication information with the first management module 230 and outputs to the charging cabinet 200. The matched power supply power is obtained from the charger 100. The access signal at least indicates the connection state signal of the charging cabinet 200 and the charger 100.

[0081] In an embodiment, the charger 100 includes a master module 130 and at least two charger charging interfaces 110. At least one charger charging interface 110 is a bidirectional transmission interface, which can also be configured to access a direct current input power supply to receive direct current input power. The master module 130 detects when at least one charger charging interface accesses a direct current input power supply and outputs the direct current input power to other charger charging interfaces.

[0082] The charger charging interface 110 of the charger can be designed as a bidirectional transmission interface, that is, it can be used for both output power and input power. When the bidirectional transmission interface accesses a direct current input power supply, the charger 100 controls the conversion of the input direct current input power into power supply power and outputs it to other charger charging interfaces 110 to supply power to the corresponding devices.

[0083] The direct current input power supply can be an energy storage power supply, a battery pack, a photovoltaic assembly, a car battery, etc. When users are in an outdoor environment and cannot obtain alternating current, they can also use a direct current input power supply as a power supply to supplement the power of the battery pack required by the electric tool in time through the charger 100, which not only expands the power supply form but also relieves the user's power anxiety.

[0084] In an embodiment, when the first management module 230 is powered by the first power supply circuit, if the first management module 230 determines that the charging cabinet 200 has no power demand, it will be powered off after a first preset time to reduce power loss. The first preset time can be set to 5 minutes. If the first management module 230 determines that the charging cabinet 200 has any power demand, it will maintain power supply by the battery pack and maintain a second preset time. It can be understood that the charger 100 can be in a discharging state for other charger charging interfaces. Even if the charging cabinet 200 informs the charger 100 of the access state, the charger can not be able to immediately implement power supply to the charging cabinet 200.

[0085] Therefore, in practical application, the charger 100 usually needs to wait for the operation of other charging interfaces to be at least partially completed before providing power to the charging cabinet 200, that is, the charging cabinet 200 needs to wait for a period of time before it can be powered. Taking charging at night as an example, in order to avoid the charging cabinet 200 from being unable to start up, the charging cabinet 200 will maintain power supply to the first management module 230 for a period of time when the user controls the first management module 230 to start up. Since power is supplied only to the first management module 230, the power consumption is relatively small and is at an acceptable level. Alternatively, the first preset time is set to 10 hours, which can meet the charging time limit of most nights.

[0086] In an embodiment, referring to Figure 5 The charging cabinet 200 further comprises a heating module 242, which is at least partially arranged in the first housing 240. Specifically, the heating module 242 is arranged on the inner side of the first housing 240 and can be arranged on the side and / or bottom of the first housing 240 to increase the temperature inside the charging cabinet 200. The heating module 242 comprises various heating modes, such as direct heating of air or heating of heat sinks. It can be understood that when the charging cabinet 200 works outdoors or in cold winter, the extremely low temperature is not suitable for battery pack charging and the charging efficiency is extremely low. Therefore, the heating module 242 needs to be arranged in the charging cabinet 200 to cope with the adverse effects of low temperature environment.

[0087] Further, the charging cabinet 200 usually has a preset charging low temperature lower threshold and a charging low temperature upper threshold, which can be realized by software or hardware. For example, a simple comparator or hardware circuit can be used to set the above-mentioned thresholds, or the thresholds can be preset in the first management module 230 and used to control whether to heat based on the comparison result of the thresholds and the actual temperature. Taking the software mode as an example, the first management module 230 is preset with a charging low temperature lower threshold and a charging low temperature upper threshold, wherein the charging low temperature lower threshold is the lower limit condition for enabling the heating module, and the charging low temperature upper threshold is the upper limit condition for stopping the heating module. That is, when the first management module 230 judges that the detected real-time temperature of the charging cabinet 200 is lower than the charging low temperature lower threshold, a heating instruction is generated to the heating module 242, and the heating module 242 performs a heating operation in response to the heating instruction; when the first management module 230 judges that the detected real-time temperature of the charging cabinet 200 is higher than the charging low temperature upper threshold, a stop heating instruction is generated to the heating module 242, and the heating module 242 performs a stop heating operation in response to the stop heating instruction.

[0088] In an embodiment, the charging cabinet 200 is further provided with a heating fan used in conjunction with the heating module 242. When the heating module 242 is activated, the fins on the inner side of the bottom of the first shell 240 can be heated. In order to achieve temperature balance in the accommodation cavity of the charging cabinet 200, a heating fan is usually used in conjunction with the heating module 242, that is, when the heating module 242 performs heating operation, the heating fan is turned on at the same time to blow hot air from the heated fins to various parts in the accommodation cavity, thereby improving the efficiency and effect of heating.

[0089] In an embodiment, the charging cabinet 200 further comprises a cooling module 244 which is at least partially arranged in the first shell 240 to avoid the risk of low charging efficiency and safety due to high ambient temperature, high temperature of the battery pack during charging, or high temperature of the charging cabinet itself. The cooling module 244 is usually a fan, which is usually arranged near the charging interface 211 of the charging cabinet to improve the cooling effect.

[0090] Similar to the heating module 242, at least a preset lower threshold of high charging temperature is usually set, which can be realized by software or hardware. For example, a simple comparator or a hardware circuit can be used to set the above-mentioned threshold, or the first management module 230 can be used to preset the above-mentioned threshold and control whether cooling is needed based on the comparison result of the threshold and the actual temperature. Taking the software as an example, the first management module 230 is preset with a preset lower threshold of high charging temperature as a lower limit condition for activating the cooling module. That is, when the first management module 230 determines that the real-time temperature of the detected charging cabinet 200 is higher than the lower threshold of high charging temperature, a cooling instruction is generated to the cooling module 244, and the cooling module 244 performs cooling operation in response to the cooling instruction.

[0091] Of course, a stop cooling threshold can also be preset. For example, when the first management module 230 determines that the real-time temperature of the detected charging cabinet 200 is not higher than the stop cooling threshold, a stop cooling instruction is generated to the cooling module 244, and the cooling module 244 stops cooling in response to the stop cooling instruction.

[0092] In an embodiment, the cooling module 244 can also stop in response to the activation of the heating module. That is, during the cooling operation of the cooling module 244, the first management module 230 generates a heating instruction, which means that cooling is no longer needed, and a stop cooling instruction is generated to stop the action of the cooling module. It can be understood that the cooling module 244 can perform cooling operation in response to any one of the activation of the heating module and the reaching of the preset lower threshold of high charging temperature.

[0093] The temperature of the charging cabinet at least includes at least one of the ambient temperature in the charging cabinet, the temperature of the battery pack, and the temperature of the first management module.

[0094] In an embodiment, the cooling module 244 comprises at least one air inlet fan and at least one air outlet fan, wherein the air inlet fan is configured to draw in external cold air into the charging cabinet 200, and the air outlet fan is configured to blow out hot air in the charging cabinet 200 from the charging cabinet 200. When the cooling operation is performed, the air inlet fan and the air outlet fan can be started simultaneously.

[0095] Preferably, the heating module 242 and the cooling module 244 are powered by the power provided by the charger. In order to avoid the power loss of each battery pack to be charged in the charging cabinet 200, the external power received from the charging cabinet 200 is preferentially used to power each module.

[0096] In an embodiment, the charging cabinet further comprises a display module 246; the display module 246 can be selectively arranged on the upper cover 250, or on the power supply device 260, or at any suitable position on the charging cabinet 200, which is not limited here.

[0097] The display module 246 is configured to display at least one of the following: the connection state of the charger, the power supply state of the charger, the charging state of the charger to the charging cabinet, the access state or the charging state or the charging time of each charging interface of the charging cabinet, the electrical parameters of the battery pack accessed by each charging interface of the charging cabinet, the continuous working time of the charging cabinet or the charger, the date, the temperature, the communication state, the cooling state, and the heating state. The specific display information is not limited thereto.

[0098] In an embodiment, the charging cabinet 200 further comprises a locking module 247, which is at least partially arranged on the upper cover 250 and is configured to unlock and lock the upper cover 250 with the first shell 240. Through the locking module, the user can lock the charging cabinet 200 to play a role of theft prevention, rain prevention, fire prevention, etc. during the charging process.

[0099] In an embodiment, the locking module 247 comprises at least one of a mechanical locking mode and a power locking mode; the mechanical locking mode usually comprises a mechanical lock; and the power locking mode usually comprises a power-locked lock.

[0100] Specifically, when the locking module 247 adopts the power locking mode, the locking module 247 locks the upper cover 250 of the charging cabinet with the first shell 240 in response to the received locking control signal sent by the first management module 230.

[0101] In an embodiment, the charging cabinet 200 can further comprise a wireless communication module 248 configured to wirelessly communicate with an external device. For example, when the charging cabinet 200 establishes wireless communication with a user mobile device, the user can generate a locking instruction on the user mobile device and send it to the charging cabinet 200, and the first management module 230 controls the locking module 248 to lock the upper cover with the first shell based on the locking instruction.

[0102] In an embodiment, the charging cabinet 200 is further provided with a trigger key 249 for activating the charging cabinet 200, i.e. starting the power supply to the first management module 230 for further charging work. When the trigger key 249 is triggered externally, the charging cabinet 200 is activated, and the display module 246 is lit up at the same time. The trigger key 249 can be optionally arranged on the power supply device 260, and of course can also be arranged at other suitable positions of the charging cabinet 200, which is not limited here.

[0103] Specifically, in one implementation, the trigger key 249 can send an activation signal to the first management module 230 in response to external triggering; the first management module 230 detects the power supply state of the charger connected to the charging cabinet 200 in response to the activation signal; accordingly, the first management module 230 judges that the power supply state represents that the charger 100 allows the charging power to be output to the charging cabinet 200, and controls to continuously output the power supply signal to realize the power supply of the first management module 230; in an embodiment, considering that the charging cabinet 200 itself has no stored power, the power supply of the first management module 230 is first supplied by one of the battery packs on the charging cabinet 200, and after a certain period of time, to avoid unnecessary power loss of the battery pack, it will be converted to be supplied by the charger. When the first management module 230 judges that the power supply state represents that the charger does not allow the charging power to be output to the charging cabinet 200, it controls to stop outputting the power supply signal after a first preset time, to disconnect the power supply of the first management module 230.

[0104] In an embodiment, when the first management module 230 judges that all charging interfaces 211 of the charging cabinet have no charging demand, the charging cabinet 200 fails, or the continuous working time of the charging cabinet 200 exceeds a second preset time, it controls to stop outputting the power supply signal to disconnect the power supply of the first management module 230. That is, when the charging cabinet 200 has the above situation, it is not necessary to continue charging or not suitable to continue charging, and then the charging operation is stopped to prevent unnecessary loss of the fully charged battery pack, or to ensure the charging safety of the charging cabinet.

[0105] In an embodiment, please refer to Figure 2The charger charging interface 110 is arranged on the side of the charger 100, and the same charger charging interface 110 can be provided with the first and second matching structures to be able to respectively plug in battery packs of different types. In an embodiment, the battery packs plugged into the charger 100 include at least two different types of battery packs. Different types of battery packs refer to at least one parameter of the battery pack being different, for example, one or more of the size, type of battery cell, and capacity being different. For example, two battery packs of the same type of battery cell and capacity but different sizes, or two battery packs of the same type of battery cell and size but different capacities, or two battery packs of the same size and capacity but different types of battery cell.

[0106] In an embodiment, the charger 100 can further include, but is not limited to, at least one charger output interface arranged on the main body of the charger 100, and the charger 100 is further configured to output charging power to the charging cabinet 200 through the charger charging interface 110 and / or the charger output interface.

[0107] In an embodiment, the charging cabinet 200 can include at least two forms. One form is that the charging cabinet 200 is provided with the power supply device and other parts as described above in the accommodation cavity, and the charger cannot be arranged in the charging cabinet 200. Another form is that the charging cabinet 200 includes a second accommodation cavity that can removably accommodate the charger 100. In an embodiment, the accommodation cavity can also removably accommodate the battery pack connected to the charger charging interface 110 and / or the battery pack connected to the charging cabinet charging interface of the charging cabinet 200. The battery pack connected to the charger charging interface 110 and the battery pack connected to the charging cabinet charging interface of the charging cabinet 200 can be the same type of battery pack or different types of battery packs. For example, the battery pack connected to the charger charging interface 110 and the battery pack connected to the charging cabinet charging interface of the charging cabinet 200 can be two battery packs of the same type of battery cell and capacity but different sizes, or two battery packs of the same type of battery cell and size but different capacities. Specifically, the battery pack connected to the charger charging interface 110 can be a backpack-type battery pack. The battery pack connected to the charging cabinet charging interface of the charging cabinet 200 can be a handheld battery pack, but the present application is not limited thereto.

[0108] Specifically, in an embodiment, the power input cable 220 at least includes the manner of cable and adapter plug, that is, the charging cabinet 11 can realize electrical connection with the charger 10 by the manner of cable only, or realize electrical connection by the manner of using the adapter 30 to plug the charging seat of the charger 10. Among them, the cable can be arranged on the base of the charger 10, and the interface of the cable can be a total plug seat of the bus cable. If the charging cabinet 11 uses the adapter to access the charger, the plug position needs to be arranged at a suitable position on the base of the charger 10, or the adapter 30' with the interface form of the battery pack (for example, a handheld battery pack) can be directly inserted into the charger charging interface of the charger 10, so that the charging cabinet 11 can receive the charging power provided by the charger 10 through the adapter.

[0109] In an embodiment, as shown in Figure 2 The input power of the charging cabinet 200 is preferably a direct current input power. The direct current input power can include various forms, that is, the charger 100 has various forms, such as an AC-powered charger 10 providing a direct current input power after AC / DC conversion, a direct current-powered charger providing a direct current input power to the charging cabinet 11, an energy storage device 20 providing a direct current input power, and the like, a direct current power output by a photovoltaic panel, a car battery, a charging pile, a generator, a car engine, and the like. The AC-powered charger is provided with an AC / DC module for converting AC power into direct current power output to provide the charging cabinet 11. If the direct current input power is provided by the direct current-powered charger, the charger performs DC / DC conversion to provide the charging cabinet 11 with direct current input power. If the direct current input power is provided by the energy storage device 20, the energy storage device 20 can select to use AC input to convert direct current power to provide direct current output, or select to use the power of the energy storage module to provide direct current output to the charging cabinet.

[0110] It should be noted that in an embodiment, regardless of the form of the charger, the charging cabinet 200 actively sends the request information of the power demand, and the charger responds to the power demand of the charging cabinet 200 to match the output power supply; that is, the charging parameter management of the charging cabinet 200 is controlled by the charging cabinet 200. In another embodiment, regardless of the direct current input power provided by the charger, the charging cabinet 11 is controlled by the charging device actually accessed to the charging cabinet. That is, the charging device controls the specific charging process of the charging cabinet, and the charging cabinet 11 does not control the charging of each charging cabinet charging interface, and only distributes power to each charging cabinet charging interface.

[0111] As shown in Figure 5As shown, in an embodiment, the charger 100 further comprises an input power interface 140, a master control module 130 and a charging circuit 120. The master control module 130 is configured to output a power processing control signal to the charging circuit 120 when detecting the input power is connected. The charging circuit 120 is configured to process the power provided by the input power to output charging power according to the received power processing control signal.

[0112] In an embodiment, the input power comprises at least an alternating current (AC) input power, and the charger 100 is configured to connect the AC input power through the input power interface 140. In addition, the input power can further comprise, but not limited to, a direct current (DC) input power, and the charger 100 is configured to connect the DC input power through the input power interface 140.

[0113] In an embodiment, the charger 100 comprises at least two charger charging interfaces 110. The input power comprises a DC input power, and the charger 100 is configured to connect the DC input power through the charger charging interface 110. The charger 100 is further configured to receive the DC input power connected through the charger charging interface 110 and output charging power to the charging cabinet 200. Specifically, for example, the DC power connected with the charger charging interface 110 can be used as the DC input power to charge the charging cabinet 200 connected with the charger.

[0114] In an embodiment, continuing to refer to Figure 5 The charging cabinet 200 further comprises a first management module 230 arranged in the power supply device 260. The first management module 230 is configured to establish a communication connection with the charger, send the first electrical parameter information of the charging cabinet 11 to the charger, and receive the communication information sent by the charger.

[0115] In the embodiment, the power supply of the charging cabinet 200 is provided by the charger, and thus the parameters of the charging cabinet 200 itself, i.e., the first electrical parameter information, need to be sent to the charger. The charger generates at least a control instruction according to the first electrical parameter of the charging cabinet 200 and according to its own parameters and sends the control instruction to the charging cabinet 200. The charging cabinet 200 receives the communication information of the charger provided by the charger, which comprises various electrical parameters and control instructions, so as to manage the charging cabinet 200 based on the information.

[0116] It can be understood that, in order to simplify the design of the charging cabinet 200, part of the charging management function can be integrated into the charger 100, i.e., at least the power supply parameters output to the charging cabinet 200 are determined by the charger 100 and sent to the charging cabinet 200 for execution, i.e., the charger 100 controls part of the charging control of the charging cabinet 200.

[0117] Of course, the first management module 230 also performs partial charging control. In an embodiment, the first management module 230 is further configured to control at least one of the following according to the first electrical parameter information of the charging cabinet 230 itself and the communication information sent by the charger: parameter acquisition of the charging cabinet, power distribution to each charging interface 211 of the charging cabinet, dynamic monitoring of each charging interface 211 of the charging cabinet, fault detection feedback and processing.

[0118] Specifically, to ensure the normal operation of the charging cabinet 200, it is necessary to obtain the electrical parameters of the charging cabinet in real time to further manage and control based on the electrical parameters. When the charging cabinet 200 receives charging power from the charger, the power distribution to each charging interface 211 of the charging cabinet is controlled according to the preset priority order, and the charging state of each charging interface 211 of the charging cabinet is monitored in real time; during the entire charging process, the first management module 230 also needs to perform fault detection and fault processing on each module of the charging cabinet 200.

[0119] Optionally, the preset priority order at least includes the order of the charging interface 211 of the charging cabinet, the insertion order of the battery pack, the order of the capacity of the battery pack from high to low or from low to high, the order of the remaining power of the battery pack from high to low or from low to high, the order of the charging time of the battery pack from long to short or from short to long, the order of the charging rate of the battery pack from high to low or from low to high, the order of the temperature of the battery pack from high to low or from low to high, and the like. The priority order can be set according to actual needs, which is not limited specifically here. In particular, the priority order can also be set by wireless communication using a mobile terminal for remote control.

[0120] In an embodiment, the main control module 130 is further configured to generate a charging control signal according to the second electrical parameter information of the charger 100 and the first electrical parameter information of the charging cabinet 200, to control the output of the charging power to the charger charging interface 110 and / or the output of the charging power to the charging cabinet 200.

[0121] Specifically, in an embodiment, the first electrical parameter information includes at least one of the following: the number of charging interfaces 211 of the charging cabinet 200, the load demand parameter on the charging interface 211 of the charging cabinet 200, the safety parameter of the charging cabinet 200, and the fault threshold of the charging cabinet 200. In an embodiment, the second electrical parameter information includes at least one of the following: the electrical parameter of the charger charging interface, the charging capacity parameter of the charger 100, the safety parameter of the charger 100, and the fault threshold of the charger 100.

[0122] In an embodiment, the first electrical parameter information can include at least a parameter representing a load state of the charging cabinet, and the second electrical parameter information can include at least a parameter representing a load state of the charging interface of the charger. The charging control signal can include at least a charging priority signal. The master control module 130 can be further configured to generate a charging priority signal for the charging interface 110 of the charger and / or the charging cabinet based on the parameter representing the load state of the charging interface of the charger and the parameter representing the load state of the charging cabinet, so as to control the charging circuit to output charging power to the charging interface 110 of the charger and / or the charging cabinet (e.g., the charging cabinet 200) according to the charging priority.

[0123] In an embodiment, the charging priority signal can represent a preset priority order. The preset priority order can include at least a sequence of the charging interface 110 of the charger and the charging interface 211 of the charging cabinet, a sequence of the battery pack insertion, a sequence of the capacity of the battery pack from high to low or from low to high, a sequence of the remaining power of the battery pack from high to low or from low to high, a sequence of the charging time of the battery pack from long to short or from short to long, a sequence of the charging rate of the battery pack from high to low or from low to high, a sequence of the temperature of the battery pack from high to low or from low to high, etc. The priority order can be set according to actual needs, and is not limited herein. In particular, the priority order can be set remotely by using a mobile terminal through wireless communication.

[0124] In an embodiment, the master control module 130 can be further configured to control at least one of the charging mode of the charger 100, the power output of each charging interface 110 of the charger 100, the fault detection and processing of the charger 100 and / or the charging cabinet 200 based on the first electrical parameter information and the second electrical parameter information.

[0125] In particular, to ensure the normal cooperation of the charger 100 and the charging cabinet 200, the electrical parameters of the charger 100 and the charging cabinet 200 need to be obtained in real time, so as to further manage and control based on the electrical parameters. When the charger 100 and the charging cabinet 200 cooperate, the charging control is performed by the charger, i.e., at least one of the charging mode of the charger 100, the power output of each charging interface 110 of the charger 100, and the fault detection and processing of the charger 100 and / or the charging cabinet 200.

[0126] In an embodiment, the charging system can further comprise a wireless communication module 248, which can be optionally arranged in the charger 100 or the charging cabinet 200. Taking the case that the wireless communication module 248 is arranged in the charger 100, the master control module 120 is further configured to control at least one of the following: receiving a control instruction sent by the power equipment through the wireless communication module 120, and outputting a corresponding charging control signal according to the control instruction; receiving a program update instruction sent by the power equipment through the wireless communication module 248, and updating the program of the charger 100 and / or the charging cabinet 200 according to the program update instruction; and sending device parameter information of at least one of the battery pack, the charger 100 and the charging cabinet 200 to the power equipment through the wireless communication module 248.

Please refer to Figure 6 The charging system comprises a charger 100a, a first charging cabinet 200a and at least one second charging cabinet 300 Figure 6 only one is shown in the figure, but the present application is not limited thereto.

[0130] The charger 100a comprises a charger charging interface 110a and a master control module 130a. In an embodiment, the charger 100a can further comprise a charger output interface 150a.

[0131] In an embodiment, the first charging cabinet 200a comprises a first management module 230a and an output interface. The output interface of the first charging cabinet 200a at least comprises a charging cabinet charging interface 211a.

[0132] Specifically, the structure and / or working principle of at least one of the charger charging interface 110a, the master control module 130a, the first management module 230a in the first charging cabinet 200a, and the charging cabinet charging interface 211a in the charger 100 can refer to Figures 1-6 and the corresponding description, which will not be repeated here.

[0133] In an embodiment, the second charging cabinet 300 is used to be connected with the charger charging interface 110 and / or the charger output interface 150a of the charger 100a to receive the charging power provided by the charger 100a. In other embodiments, the second charging cabinet 300 can also be connected with the output interface of the first charging cabinet 200a to receive the charging power provided by the charger 100a.

[0134] Specifically, in an embodiment, the first charging cabinet is connected to the charger, and the second charging cabinet is connected to the first charging cabinet, realizing two-stage connection. The second charging cabinet 300 comprises a second management module 330, which is temporarily powered by the battery pack accessed in the second charging cabinet 300 to realize startup and sends an access signal to the first charging cabinet 200a. The first management module 230a of the first charging cabinet 200a receives the access signal and establishes communication with the second management module 330. At this time, the first charging cabinet 200a accesses the charger 100a in the same way, and when the first charging cabinet 200a obtains power supply power from the charger 100a, if the access signal is received from the second charging cabinet 300, and based on the information of each charging cabinet charging interface accessed by the charging cabinet 200a, the power supply power is output to each charging cabinet charging interface according to the priority, including the power supply power output to the second charging cabinet 300. Thus, the charger 100a supplies power to the multiple charging cabinets accessed in sequence to charge the multiple battery packs.

[0135] In another embodiment, the second charging cabinet 300 comprises a second management module 330. The second management module 330 is used to establish a communication connection with the master control module 130a of the charger 100a to receive the second electrical parameter information and the charging control signal sent by the master control module 130a, and send the third electrical parameter of the second charging cabinet 300 to the master control module 130a or through the first management module 230a of the first charging cabinet 200a to the master control module 130a, and send the corresponding charging control instruction to control the charging process of the second charging cabinet 300.

[0136] Specifically, in an embodiment, the second management module 330 is configured to control at least one of the parameter collection of the second charging cabinet 300, the power distribution of the charging cabinet charging interface of each second charging cabinet 300, the charging management of the second charging cabinet 300, the fault detection feedback and processing according to the third electrical parameter information.

Wherein, the at least one second charging cabinet 300 can be connected with the output interface of the first charging cabinet 200a, or directly connected with the interface of the charger 100a to receive the charging power provided by the charger 100a, which can further improve the flexibility. And the charging power of the first charging cabinet 200a and the second charging cabinet 300 can be provided by the charger 100a, therefore, the corresponding charging circuit does not need to be set in the first charging cabinet 200a and the second charging cabinet 300, which can simplify the electrical design of the first charging cabinet 200a and the second charging cabinet 300, avoid the redundancy of the charging circuit, and further reduce the cost of the charging system. In addition,

[0138] The application also provides a specific application of the charging system. As Figures 1-5 The embodiment of the application provides a charging system 1, which includes a charger 100 and a charging cabinet 200. The charger 100 is provided with a charger charging interface 110, which is used to connect a battery pack to output power supply power to the charger charging interface 110 to charge the battery pack. The charging cabinet 200 includes a charging cabinet main body 210 and a power input cable 220, wherein one end of the power input cable 220 is connected to the charging cabinet main body 210, and the other end is detachably connected to the charger charging interface 110 to output the power supply power output by the charger charging interface 110 to the charging cabinet main body 210; at least one charging cabinet charging interface 211 is arranged in the charging cabinet main body 210, which is used to connect the battery pack to charge the battery pack with the power supply power obtained by the charging cabinet.

[0139] When the second end of the power input cable 220 is connected to the charger charging interface 110, the charging cabinet positive terminal 222, the charging cabinet negative terminal 224 and the charging cabinet communication terminal 226 of the second end are respectively connected with the charger positive terminal 112, the charger negative terminal 114 and the charger communication terminal 116 of the charger charging interface 110 to realize communication and power transmission.

[0140] The charging cabinet 200 further comprises a first management module 230, and a power supply circuit of the first management module 230 comprises a first power supply circuit and a second power supply circuit. The battery pack connected with the charging cabinet charging interface 211 is connected with the first power supply circuit to supply power to the first management module 230, and the charger 100 is connected with the second power supply circuit to supply power to the first management module 230. When the first management module 230 is in different states, different power supply circuits are selected.

[0141] The charger comprises a master control module 130. A trigger key is arranged on the charging cabinet 200 to start the first management module 230. When the trigger key is externally triggered, for example, a user performs a starting operation, the first power supply circuit is turned on, and the battery pack in the charging cabinet supplies power. At this time, the first management module 230 enters a working state from a closed state, and sends an access signal representing an access state to the charger. Correspondingly, the master control module 130 of the charger 100 detects the access signal and hopes to establish communication with the charging cabinet 200.

[0142] When the charger 100 allows to provide power supply power to the charger charging interface 110 where the charging cabinet 200 is located, the charger 100 establishes communication with the charging cabinet 200 and provides power supply power.

[0143] Specifically, after the charging cabinet 200 establishes communication with the charger 100, the first management module 230 sends power consumption parameter information required by the charging cabinet 200 to the master control module, wherein the power consumption parameter information represents the power consumption demand of the charging cabinet. For example, the power consumption parameter information at least comprises a battery pack charging demand parameter of the battery pack connected with the charging cabinet charging interface 211. In response to the power consumption parameter information, the master control module 130 controls to match the power supply power, and outputs the power supply power to the charging cabinet 200 through the charger charging interface 110. Thus, the charging cabinet 200 obtains power supply from the charger 100.

[0144] Further, after the charging cabinet 200 obtains power supply power from the charger charging interface 110, the second power supply circuit is switched to supply power to the first management module 230, that is, the power supply is changed to the charger 100, so as to reduce unnecessary power loss of the battery pack.

[0145] When the charger 100 cannot provide power supply power to the charger charging interface 110 where the charging cabinet 200 is located temporarily, the first management module 230 of the charging cabinet 100 is maintained to be powered by the first power supply circuit until the power supply power of the charger is obtained, or until a preset time is reached.

[0146] In this embodiment, the charging cabinet 200 charges one battery pack at a time, so after the first management module 230 is started, it detects the battery pack parameters of the battery pack connected to each charging interface 211 of the charging cabinet, filters out the battery pack allowed to be charged according to the battery pack parameters, and selects the battery pack with the highest charging priority among the battery packs allowed to be charged in the order of the positions. It can be understood that the basis for determining the priority is not limited to this, and can be designed according to actual needs, for example, the battery pack parameters such as capacity, temperature, and remaining power can be used for judgment.

[0147] When the charging cabinet 200 determines the battery pack with the highest charging priority, it uses the charging demand parameters of at least the battery pack as the power consumption parameter information of the entire charging cabinet 200, and communicates with the charger 100 using the first communication protocol. Among them, the battery pack and the charger 100 also communicate using at least the first communication protocol. That is, the charging cabinet 200 communicates with the charger 100 as a battery pack, power consumption demand, and the same communication protocol to obtain power supply power. Therefore, the charger has no reason not to provide power supply power for a battery pack with normal charging demand, and thus ensures that the charging cabinet 200 can obtain power supply power from the charger 100.

[0148] When the charging cabinet 200 completes charging the battery pack with the highest charging priority, the first management module 230 determines the next battery pack to be charged as the battery pack with the highest charging priority, and sends the power consumption parameter information to the charger 100 using the same logic to obtain matching power supply power, thereby achieving the full charging of multiple battery packs in the charging cabinet 200.

[0149] Before resting, the user inserts the battery pack to be charged into the charging cabinet 200, and connects the charging cabinet 200 to the power supply source such as the charger 100, and after starting the charging cabinet 200, the charging cabinet 200 can automatically complete the power acquisition from the charger 100 and the charging of the battery pack according to the above logic, so that multiple battery packs can be fully charged in one night without the user getting up at night to operate, greatly facilitating the user's use.

[0150] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
