[0002] With the development of battery technology, batteries have become core components in the power and communications industries, providing safe, stable and reliable power protection for secondary system loads in power systems, ensuring the normal operation of user equipment, communication equipment and automation equipment.

[0003] The life of a battery is usually 8 to 12 years. However, due to factors such as overcharging and over-discharging, mixed use of products, and excessively high ambient temperatures, most batteries do not reach the preset lifespan during use and are usually scrapped within 1 to 2 years, resulting in a large number of waste batteries.

[0004] These used batteries contain many substances that are extremely destructive to the environment, which usually flow from the batteries to the external environment in the form of battery leakage. If these used batteries cannot be properly disposed of, they will cause great environmental pollution and trigger safety accidents.

[0031] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0032] In one embodiment, Figure 1 As shown, a battery storage device 1 is provided, which includes: an alarm component 10, a tray 11, a liquid collection box 12, an isolation plate 13, and a liquid leakage sensor 14.

[0033] The alarm component 10 may be a component for generating an alarm, for example, it may be configured to execute an alarm operation in response to a received alarm instruction.

[0034] Optionally, the alarm instruction may be issued by the liquid leakage sensor 14 , and the alarm component 10 performs an alarm operation after receiving the alarm instruction issued by the liquid leakage sensor 14 .

[0035] Optionally, if the battery storage device 1 is also equipped with a voltage sensor, a temperature sensor, a capacitance sensor, etc., the alarm instruction can also be issued by the voltage sensor, the temperature sensor, the capacitance sensor, etc. After receiving these alarm instructions, the alarm component 10 performs the alarm operation.

[0036] Specifically, the alarm component 10 is an audible and visual alarm circuit. When the alarm group 10 receives an alarm command, it controls the speaker to emit a sound alarm and the light to emit a light alarm. The operation and maintenance personnel can make corresponding responses based on these audible and visual signals.

[0037] Optionally, the alarm component 10 may also include a display screen, that is, the alarm instruction is directly displayed on the display screen in the form of text content for reference by operation and maintenance personnel.

[0038] The tray 11 is used to store batteries and other related components.

[0039] Specifically, the tray 11 is a rectangular parallelepiped as a whole. The tray 11 can be divided into two layers, separated by an isolation plate in the middle. The upper layer is used to store batteries, and the lower layer is used to prevent liquid collection box 12 and other components. The material of the tray 11 is acid-corrosion-resistant material, which can prevent leakage from corroding and damaging the tray.

[0040] Optionally, at least four columns are provided on the tray 11 , and fences that can move up and down are installed on the columns, and the fences are used to prevent the batteries stored on the isolation plate 13 from falling.

[0041] Specifically, when there are many batteries in the tray 11, the fence can be moved upward to prevent the batteries above from falling. When there are fewer batteries in the tray 11, the fence can be moved downward to facilitate transportation when more batteries are stored in the tray 11.

[0042] Optionally, universal wheels 15 are provided at the bottom of the tray 11 .

[0043] Specifically, when the operation and maintenance personnel need to move the tray 11 or move the battery storage device, they only need to push the universal wheel according to their needs. The universal wheel can help the operation and maintenance personnel save manpower and do not require a large amount of manpower to move the tray 11.

[0044] Optionally, the universal wheel can be a universal wheel with an electric power assist system, so that when a large number of batteries are placed in the battery storage device, it can help operation and maintenance personnel move the device, greatly saving manpower.

[0045] The liquid collecting box 12 is used to collect battery leakage.

[0046] The liquid collection box 12 is made of acid corrosion resistant material to prevent liquid leakage from corroding and damaging the liquid collection box.

[0047] Optionally, the liquid collection box 12 is located in the lower layer of the tray 11, below the isolation plate 13. When the battery leaks, the leaked liquid can pass through the isolation plate 13 and drip into the liquid collection box 12, preventing the battery leak from flowing into the external environment.

[0048] The isolation plate 13 is used to store the battery and separate the battery from the liquid collection box 12.

[0049] Specifically, the isolation plate 13 is located on the top of the liquid collection box 12 and is used to store batteries. It is also used to separate the batteries from the liquid collection box 12 to prevent leakage from contacting the batteries and causing corrosion to the outside of the batteries. The isolation plate 13 is made of acid-resistant corrosion-resistant material, which can prevent leakage from corroding and damaging the isolation plate.

[0050] There are small holes on the isolation plate 13. When leaked liquid flows out of the battery, it can flow into the liquid collection box 12 below the isolation plate through the gaps on the isolation plate 13.

[0051] The leakage sensor 14 is a sensor for detecting whether there is battery leakage in the liquid collection box 12. It is used to send an alarm instruction to the alarm component 10 when it detects that the battery stored on the isolation plate has leakage.

[0052] Optionally, the leakage sensor 14 can be a liquid detection sensor fixed at the bottom of the liquid collection box 12 to detect battery leakage. When battery leakage flows into the liquid collection box 12, the liquid detection sensor can send an alarm signal to the alarm component 10.

[0053] Optionally, the liquid leakage sensor 14 may include: a liquid leakage plate located at the bottom of the liquid collection box 12 and a capacitance detection chip located between the liquid leakage plate and the bottom of the liquid collection box 12 .

[0054] Among them, a number of small holes are opened on the leakage plate;

[0055] The capacitance detection chip is used to perform capacitance detection on battery leakage between the leakage plate and the bottom of the liquid collection box 12. When the capacitance of the battery leakage is detected to be greater than the capacitance threshold, it is determined that the battery stored on the isolation plate 13 is leaking. The battery leakage between the leakage plate and the bottom of the liquid collection box 12 is caused by the battery stored on the isolation plate 13 flowing in through the small holes in the leakage plate.

[0056] Specifically, there is a certain gap between the leakage plate and the bottom of the liquid collection box 12. The leakage plate is drilled with a number of small holes, through which battery leaked liquid can flow. When the battery leaks, the leaked liquid will flow through the small holes into the gap between the leakage plate and the bottom of the liquid collection box 12. The leakage plate and the bottom of the liquid collection box 12 form a capacitor. Since the capacitance of a capacitor changes when the dielectric of the capacitor changes, when the battery leaks into the gap between the leakage plate and the bottom of the liquid collection box, the dielectric of the capacitor changes, and the capacitance also changes. Therefore, when the battery leaks, this capacitance will change.

[0057] Among them, a capacitance detection chip is provided in the gap between the leakage plate and the bottom of the liquid collection box 12, which is used to detect the capacitance of the capacitor formed by the leakage plate and the bottom of the liquid collection box 12, and compare the detected capacitance with the preset capacitance threshold. When the detected capacitance exceeds the preset capacitance threshold, it is determined that the battery has leaked.

[0058] Optionally, the preset capacitance threshold can be adjusted based on sensitivity requirements. For example, the capacitance when there is no leakage can be set as the preset capacitance threshold. When the battery leaks, the leaked liquid flows through the small hole into the gap between the leakage plate and the bottom of the liquid collection box 12. At this time, the dielectric of the capacitor changes, and the capacitance changes accordingly. At this time, the capacitance detection chip detects that the capacitance has exceeded the preset threshold, and determines that the battery is leaking. Using this method, as long as there is a little leakage in the battery, it can be detected immediately.

[0059] When the leakage sensor 14 identifies that the battery is leaking, it will send an alarm instruction to the alarm component 10, and the alarm component 10 will then pass the information to the operation and maintenance personnel to deal with the battery leakage.

[0060] Optionally, in this embodiment, multiple capacitance thresholds may be set, and different alarm signals may be generated when it is detected that the capacitance of the capacitor is greater than different capacitance thresholds.

[0061] For example, two capacitance thresholds are set, namely capacitance threshold 1 and capacitance threshold 2, capacitance threshold 2 is greater than capacitance threshold 1, when the detected capacitance exceeds capacitance threshold 1, alarm instruction 1 is generated, and alarm component 10 can control the relevant alarm light to display yellow, when the detected capacitance exceeds capacitance threshold 2, alarm instruction 2 is generated, and alarm component 10 can control the relevant alarm light to display red.

[0062] Among them, the leakage plate and the capacitance detection chip are both made of acid-corrosion-resistant materials, which can prevent them from being damaged by battery leakage.

[0063] It should be noted that the battery storage device 1 of this embodiment can be used to store any batteries, and is preferably used to store discarded batteries.

[0064] The battery storage device in the above embodiment monitors the leakage of the battery by setting a leakage sensor, and then alarms the leakage through the alarm component, so that operation and maintenance personnel can understand the leakage of the battery in time and respond, avoiding environmental pollution caused by battery leakage and eliminating the safety hazards caused by battery leakage.

[0065] In order to better monitor the status of the battery, based on the above embodiment, the monitoring of the battery surface temperature is added. In this embodiment, Figure 2 As shown, the battery storage device 1 further includes a temperature sensor 16 .

[0066] Wherein, the temperature sensor 16 is fixed on the surface of the battery stored on the isolation plate 13;

[0067] The temperature sensor 16 is used to send an alarm instruction to the alarm component 10 when it detects that the surface temperature of the battery is higher than a preset temperature.

[0068] Specifically, the temperature sensor 16 is placed on the surface of the battery, for example, by affixing it to the battery surface using double-sided adhesive. Since overheating of the battery can cause explosions and other accidents, the temperature sensor 16 can monitor the battery surface temperature in real time. When the temperature detected by the temperature sensor 16 exceeds a preset temperature, an alarm instruction is sent to the alarm component 10, and the operation and maintenance personnel can then respond accordingly.

[0069] Optionally, the battery storage device 1 may be equipped with a cooling system, such as a fan or a small air conditioner. When the temperature detected by the temperature sensor 16 is higher than a preset threshold, the cooling system may be controlled to cool the battery to below the preset threshold.

[0070] In the above embodiment, by providing a temperature sensor on the battery surface, real-time monitoring of the battery surface temperature is achieved. In this way, operation and maintenance personnel can respond to the battery surface temperature to prevent safety accidents such as battery explosion caused by excessively high battery surface temperature.

[0071] Based on the above embodiment, this embodiment describes the circuit of the battery storage device 1. Figure 3 As shown, the battery storage device further includes: a power management circuit 17;

[0072] The power management circuit 17 is used to detect the residual voltage of the battery through a wire connected to the battery terminal, and discharge the battery when it is detected that the residual voltage of the battery is higher than a voltage threshold.

[0073] Specifically, the power management circuit 17 can monitor the battery voltage in real time, and can use a voltage sensor to detect the battery voltage. When it is detected that the remaining voltage of the battery is higher than a preset voltage threshold, the battery can be discharged to avoid excessive residual power in the battery, which may cause the battery to leak and cause safety accidents such as fire.

[0074] Optionally, the voltage detection of the battery here may be voltage detection of a single battery.

[0075] Preferably, the voltage detection of the battery here may be the detection of the total voltage of all batteries in the device connected in series.

[0076] Optionally, the battery storage device 1 of this embodiment may be equipped with a battery discharge circuit to discharge the remaining battery charge. During discharge, the remaining battery charge may be completely discharged, or a discharge threshold may be set such that discharging stops when the charge level falls below the discharge threshold.

[0077] The above embodiment detects the voltage of the battery. When the detected voltage is higher than a preset voltage threshold, it is considered that the remaining power in the battery is too high, and the battery is discharged. This can keep the battery at a low power level and reduce the safety risks of battery storage.

[0078] On the basis of the above embodiment, in order to better process the remaining power of the battery, this embodiment adds some other circuits on the basis of the power management circuit 17, such as Figure 4 As shown, the battery storage device 1 further includes: a power supply 18 , a power charging circuit 19 and a battery discharging circuit 20 .

[0079] The power supply 18 is used to provide power to the power management circuit 17 .

[0080] The power supply charging circuit 19 is used to control the battery to charge the power supply 18.

[0081] The power supply discharge circuit 20 is used to control the battery to perform discharge operation.

[0082] The power management circuit 17 is specifically configured to determine a target circuit for performing a discharge operation when detecting that the remaining voltage of the battery is higher than a voltage threshold, and discharge the battery through the target circuit.

[0083] The target circuits are a power charging circuit 19 and a battery discharging circuit 20 ; the power charging circuit 19 is used to charge the power source 18 .

[0084] The power management circuit 17 is used to determine that the target circuit for performing the discharge operation is the power charging circuit 19 when it is detected that the remaining voltage of the battery is higher than the voltage threshold and the current power value of the power supply 18 has not reached the rated power;

[0085] Specifically, the power management circuit 17 is connected to the positive and negative poles of the battery. When the residual voltage of the battery is higher than the threshold and the power supply 18 in the power management circuit 17 has not reached the rated power, the power charging circuit 19 is started to use the residual power in the battery to charge the power supply 18 in the power management circuit 17. This not only ensures that the battery will not cause safety problems due to excessive residual power, but also can utilize the residual power and save resources.

[0086] Optionally, the power supply 18 here can be a power supply that is easy to replace. When the power of one power supply reaches the rated power, other power supplies that have not reached the rated power can be replaced for charging, so as to maximize the utilization of the remaining power of the battery and minimize energy waste.

[0087] The power management circuit 17 is further configured to determine that the target circuit for performing the discharging operation is the battery discharging circuit 20 when detecting that the remaining voltage of the battery is higher than a voltage threshold and the current power value of the power source reaches the rated power.

[0088] Specifically, when the power management circuit 17 detects that the remaining voltage of the battery is higher than the voltage threshold, and at this time the power supply 18 in the power management circuit has reached the rated power and does not need to be recharged, the battery discharge circuit 20 is started to discharge the battery so that the remaining voltage in the battery is less than the preset voltage threshold.

[0089] The preset voltage threshold can be adjusted according to actual conditions. When the preset voltage threshold is 0, all the remaining power of the battery needs to be released.

[0090] The above embodiment sets up a power charging circuit and a battery discharging circuit so that when the battery has surplus power, the surplus power is first utilized and then discharged. While reducing the safety hazards caused by the surplus power in the battery, the surplus power is also reused for a second time, thereby maximizing energy utilization.

[0091] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
