Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the interior and exterior of the outline of the corresponding component; "far" and "near" refer to the distance of the corresponding component relative to another component in terms of spatial position. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] The inventors discovered through research that, in related technologies, lithium batteries generate heat during charging. Excessively high charging ambient temperatures will severely shorten the lifespan of lithium batteries, reduce their charging efficiency, and may even lead to the risk of lithium batteries running out of control and catching fire.

[0022] To achieve the above objectives, this disclosure provides a charging device, with reference to... Figures 1 to 5 As shown, the charging device includes a main body 1, an air conditioning system 3, and a fire protection system 4. The main body 1 has an internal accommodating space 11, and a battery compartment 2 is provided in the accommodating space 11. The battery compartment 2 is used to store batteries and / or charge batteries. The air conditioning system 3 is adapted to regulate the temperature of the accommodating space 11. The fire protection system 4 includes a discharge pipe 41 and a sprinkler head 42. The sprinkler head 42 is located in the accommodating space 11 and is connected to the discharge pipe 41 to provide fire protection medium.

[0023] Through the above technical solution, the temperature of the accommodating space 11 is adjustable, so that the battery compartment 2 is at a suitable temperature for battery charging. This reduces the battery's lifespan degradation caused by excessively high ambient temperatures during charging, while also improving battery charging efficiency and reducing the risk of battery thermal runaway due to excessive temperature in the battery compartment 2. Furthermore, in the event of battery thermal runaway, fire-fighting media can be sprayed through the nozzle 42 to control the fire and minimize losses.

[0024] In some exemplary application scenarios, the charging device can be used to charge drone batteries. For example, the charging device can be placed at or near a drone airport, and operators can put the drone battery to be charged into the battery compartment 2 for charging. During the charging process, the air conditioning system 3 is running to adjust the temperature of the storage space 11 at any time. For example, the suitable temperature for battery charging is 20~30°C.

[0025] In some implementations, reference Figure 1 As shown, the air conditioning system 3 may include an air conditioner 31 and an air supply duct 32. The air conditioner 31 is connected to the accommodating space 11 through the air supply duct 32, so that the air conditioner 31 supplies air to the accommodating space 11 through the air supply duct 32 to regulate the temperature of the accommodating space 11. For example, in the hot summer, the air conditioner 31 cools the accommodating space 11 to deliver cooler air, thereby lowering and maintaining the temperature of the accommodating space 11 at a suitable temperature for battery charging, reducing the possibility of battery life degradation due to excessively high charging ambient temperature. In the cold winter, the air conditioner 31 heats the accommodating space 11 to deliver warmer air, thereby raising and maintaining the temperature of the accommodating space 11 at a suitable temperature for battery charging, improving battery charging efficiency.

[0026] It is understandable that a temperature sensor can be installed in the accommodating space 11, which is connected to the air conditioner 31 for signal adjustment of the air supply temperature of the air conditioner 31.

[0027] In addition, the charging device may also include a first cabinet 5 disposed outside the main body 1, wherein the air conditioner 31 is disposed inside the first cabinet 5. Thus, the first cabinet 5 is used to provide a first space for installing the air conditioner 31. The air conditioner 31 mainly includes a refrigeration system and an air duct system. The refrigeration system includes a compressor, an evaporator, a condenser and a throttling device. The air duct system includes a fan and a heat exchange pipe. The fan is connected between the heat exchange pipe and the air supply pipe 32, or the heat exchange pipe is connected between the air supply pipe 32 and the fan. The heat exchange pipe can exchange heat with the evaporator.

[0028] For example, when the air conditioner 31 needs to send cool air at a lower temperature to the accommodating space 11, the low-temperature, low-pressure refrigerant is compressed into a high-temperature, high-pressure refrigerant by the compressor. The high-temperature, high-pressure refrigerant exchanges heat with the outside at the condenser to release heat to the outside of the first cabinet 5 and condenses. Then, it is depressurized into a low-temperature, low-pressure refrigerant through the throttling device. The gas and refrigerant in the heat exchange pipeline exchange heat at the evaporator, and the temperature decreases. Then, it is sent into the accommodating space 11 through the air supply duct 32. This cycle is repeated to reduce the temperature of the accommodating space 11.

[0029] When the air conditioner 31 needs to deliver hot air at a higher temperature to the accommodating space 11, the air conditioner 31 has a four-way valve that can change the flow direction of the refrigerant. The high-temperature and high-pressure refrigerant releases heat and condenses at the evaporator. At this time, the evaporator temporarily acts as a condenser. The gas in the heat exchange pipe exchanges heat with the refrigerant at the evaporator, and the temperature rises. Then, it enters the accommodating space 11 through the air supply pipe 32. The refrigerant after heat exchange is depressurized into a low-temperature and low-pressure refrigerant through the throttling device. The low-temperature and low-pressure refrigerant exchanges heat with the outside at the condenser to absorb heat from the outside of the first cabinet 5 and evaporate. At this time, the condenser temporarily acts as an evaporator. Then, it is compressed into a high-temperature and high-pressure refrigerant by the compressor to exchange heat with the gas in the heat exchange pipe again at the evaporator. This cycle is repeated to raise the temperature of the accommodating space 11.

[0030] It is understood that the gas in the containment space 11 can be returned to the heat exchange pipeline or fan through the return air duct (not shown in the figure) to achieve gas circulation, or the air duct system can draw fresh air from the outside, and the gas in the containment space 11 can be discharged through the vent on the main body 1 (not shown in the figure). This disclosure is not limited thereto.

[0031] In addition, the first cabinet 5 can also protect the air conditioner 31, reducing the impact of the external environment, such as rain and sunlight, on the air conditioner 31 and ensuring its normal temperature regulation function. Furthermore, the air conditioner 31 is installed in the first cabinet 5, independent of the main body 1, forming a structural module to improve the integration of the air conditioning system 3, facilitating disassembly and assembly from the main body 1, thereby enabling easy relocation of the charging device, and also facilitating the inspection and maintenance of the air conditioner 31.

[0032] It is understood that the air supply duct 32 can be connected to the first cabinet 5 in any suitable manner. For example, the air supply duct 32 can pass through the cabinet wall of the first cabinet 5 to partially extend into the first space. The outer wall of the air supply duct 32 is connected to the inner wall of the cabinet wall formed in the first cabinet 5 for the air supply duct 32 to pass through. Alternatively, a vent can be opened on the first cabinet 5, and the air supply duct 32 can be connected to the first cabinet 5 and cover the vent. This disclosure does not make any specific limitations in this regard.

[0033] In some implementations, reference Figure 1 and Figure 4 As shown, the fire protection system 4 may also include a second cabinet 43, a water storage tank 44, and a water supply pump 45. The water storage tank 44 and the water supply pump 45 are housed inside the second cabinet 43, which is located outside the main body 1. Thus, the second cabinet 43 provides a second space for installing the water storage tank 44 and the water supply pump 45. At the same time, the second cabinet 43 can also protect the water storage tank 44 and the water supply pump 45, reducing the impact of the external environment, such as rain and sunlight, on the water storage tank 44 and the water supply pump 45, and ensuring the normal water supply and fire protection function of the water storage tank 44 and the water supply pump 45.

[0034] In this way, the water storage tank 44 and the water supply pump 45 are installed in the second cabinet 43 and are independent of the main body 1, forming a structural module to improve the integration of the fire protection system 4, making it easy to disassemble and assemble with the main body 1, thereby facilitating the relocation of the charging device, and also facilitating the inspection of the fire protection medium quantity in the water storage tank 44, as well as the inspection and maintenance of the water supply pump 45.

[0035] In addition, refer to Figure 1 and Figure 3 As shown, the discharge pipe 41 may include a main pipe 411 and a branch pipe 412 connected to the main pipe 411. The branch pipe 412 passes through the main body 1 and extends into the accommodating space 11. The nozzle 42 is connected to the branch pipe 412. The water supply pump 45 is connected to the water storage tank 44 and the main pipe 411. In this way, the water supply pump 45 can drive the water in the water storage tank 44 to flow through the main pipe 411 to the branch pipe 412, and then the water will be discharged from the nozzle 42 to act on the thermally runaway battery, thereby controlling the fire and reducing the loss.

[0036] Understandably, the water flowing within branch pipe 412, after being sprayed out through nozzle 42, forms a high-pressure water mist, which can effectively cool the battery to extinguish fires caused by thermal runaway and prevent reignition. Furthermore, a level sensor can be installed in the aforementioned water tank 44 to alert operators to replenish the water in the tank when it is low. Alternatively, the water tank 44 can be connected to a water supply structure, such as a fire hydrant, to ensure sufficient fire-fighting water supply. Additionally, the fire-fighting medium can also be a liquid medium that can rapidly absorb heat, effectively prevent reignition, and has insulating properties, such as perfluorohexanone. This disclosure is not limited to these.

[0037] In some implementations, reference Figures 1 to 3 As shown, a plurality of charging units 6 are arranged along the height direction within the accommodating space 11. Each charging unit 6 may include a plurality of battery compartments 2 arranged along the width direction. The discharge pipe 41 includes a plurality of branch pipes 412 corresponding to the plurality of charging units 6, and each branch pipe 412 is provided with a nozzle 42. In this way, the multiple battery compartments 2 are integrated through the charging units 6, so as to effectively utilize the accommodating space 11 and facilitate the adaptive arrangement of the branch pipes 412. Exemplarily, the branch pipes 412 may extend along the width direction, that is, the arrangement direction of the branch pipes 412 corresponding to the plurality of battery compartments 2 of the charging unit 6. In some other embodiments, the charging unit 6 may include a plurality of battery compartments 2 arranged along the height direction, in which case the branch pipes 412 may extend along the height direction.

[0038] Furthermore, the number of nozzles 42 on each branch pipe 412 can be set to one or more. For example, each branch pipe 412 can be provided with one nozzle 42, which can spray fire-fighting medium to act on the multiple battery compartments 2 of the charging unit 6 corresponding to the branch pipe 412. Alternatively, each branch pipe 412 can be provided with multiple nozzles 42, for example, the nozzles 42 can correspond one-to-one with the multiple battery compartments 2 of the charging unit 6 corresponding to the branch pipe 412, or every two battery compartments 2 can correspond to one nozzle 42. This disclosure is not limited thereto.

[0039] In some implementations, reference Figure 3As shown, the water supply pump 45 is connected to the water storage tank 44 and each branch pipe 412. Each charging unit 6 is equipped with at least one temperature sensor 7, and a switch valve 8 is installed on the branch pipe 412. The temperature sensor 7 and the switch valve 8 corresponding to the same charging unit 6 are signal-connected, and the water supply pump 45 is also signal-connected. In this way, the temperature of the corresponding charging unit 6 can be detected by the temperature sensor 7. If the detected temperature is too high, the switch valve 8 corresponding to the charging unit 6 opens, and the water supply pump 45 starts to draw fire-fighting medium acting on the water storage tank 44. The fire-fighting medium flows through the main pipe 411 and the branch pipe 412 corresponding to the switch valve 8, and is sprayed out through the nozzle 42 to cool the charging unit 6, so as to control the fire caused by thermal runaway of the battery in one or more battery compartments 2 of the charging unit 6 and reduce the loss.

[0040] By way of example, each charging unit 6 is provided with a temperature sensor 7, which is located at the center of the charging unit 6 along the width direction, so as to be used to detect the temperature of the charging unit 6. In some other embodiments, each charging unit 6 may be provided with multiple temperature sensors 7, with each temperature sensor 7 corresponding to a battery compartment 2, and the number of switching valves 8 and nozzles 42 is set to multiple and corresponding to a battery compartment 2. This disclosure is not limited thereto.

[0041] In addition, the temperature sensor 7 can also be connected to the power controller of the charging device. If the temperature sensor 7 detects that the temperature is too high, the power controller will cut off the power to the charging device. It should be noted that the power supply of the fire protection system 4 is set independently so as not to affect the opening of the switch valve 8, as well as the normal opening of the water supply pump 45 and its function of pumping fire protection medium.

[0042] In some implementations, reference Figure 5 As shown, a shelf 9 is provided inside the main body 1, and the charging unit 6 is disposed on the shelf 9. The shelf 9 forms a water collection tank 91. The fire protection system 4 also includes a return water pipe 46 connecting the water storage tank 44 and the water collection tank 91. Thus, if the battery in the charging compartment of a certain charging unit 6 experiences thermal runaway, the fire protection medium, after cooling, can be collected in the water collection tank 91 and returned to the water storage tank 44 via the return water pipe 46 for reuse, thereby saving fire protection resources. Furthermore, the shelf 9 supports the charging unit 6 and separates adjacent charging units 6 to reduce the impact of battery thermal runaway on adjacent charging units 6. For example, the material of the shelf 9 can be a fire-resistant sealing material, such as an aerogel pad.

[0043] In some implementations, reference Figure 5As shown, at least a portion of the shelf 9 is arranged inclined to the horizontal plane to form a water collection trough 91. The water collection trough 91 is located below the shelf 9 along its height direction, thereby facilitating the flow of fire-fighting media. Furthermore, a return water inlet 10 communicating with the return water pipe 46 is formed on at least one of the side walls of the shelf 9 and the main body 1. In this way, the fire-fighting media can flow downwards at an incline on the shelf 9, be collected by the water collection trough 91, and flow through the return water inlet 10 and the return water pipe back to the water storage tank 44. It is understood that the aforementioned horizontal plane is a plane parallel to the ground when the charging device is placed on the ground for normal use.

[0044] In some implementations, reference Figure 5 As shown, there is a ventilation gap L between the shelf 9 and the side wall of the main body 1, which allows the accommodating space 11 to become a connected whole. Thus, the air supplied by the air conditioner 31 can regulate the temperature of the entire accommodating space 11 through the ventilation gap L, ensuring that each battery compartment 2 is at a suitable charging temperature. Furthermore, it simplifies the structure of the air conditioning system 3, meaning that the air conditioner 31 can be connected to the accommodating space 11 through only one air supply duct 32.

[0045] It is understood that in some other embodiments, ventilation holes penetrating the shelf 9 are provided on the shelf 9. Similarly, the accommodating space 11 can also become a connected whole through the ventilation holes. Of course, the ventilation gap L and the ventilation holes mentioned above can be provided separately or simultaneously, and this disclosure does not specifically limit them.

[0046] In some implementations, reference Figure 1 and Figure 2 As shown, the accommodating space 11 may include a first accommodating cavity 111 and a second accommodating cavity 112. The first accommodating cavity 111 is used to house the battery compartment 2, and the second accommodating cavity 112 is used to store batteries that are to be charged or have completed charging. In this way, the charging utilization rate of the charging device can be improved, so that batteries to be charged can be loaded into the battery compartment 2 in a timely manner, or batteries that have completed charging can be unloaded from the battery compartment 2.

[0047] The first receiving cavity 111 and the second receiving cavity 112 are arranged side by side along the height direction, with the first receiving cavity 111 positioned above the second receiving cavity 112. This facilitates the operator's access to and placement of batteries in the second receiving cavity 112 that are further back from the operator, i.e., those awaiting charging or those that have completed charging. The front side of the charging device is closer to the operator during normal use, while the rear side is further away from the operator during normal use. Figure 1 For example, the opening of the battery compartment 2 is located on the front side. In addition, the second receiving cavity 112 is located below the first receiving cavity 111, and it stores batteries that are to be charged or have been fully charged. The weight of this part of the battery can improve the stability of the charging device.

[0048] Furthermore, the first receiving cavity 111 and the second receiving cavity 112 can be separated by a partition 113 to block the fire-fighting medium in the event of thermal runaway of the rechargeable battery, thereby reducing the impact on the battery in the second receiving cavity 112 and improving the integrity of the battery in the second receiving cavity 112.

[0049] It is understood that the second receiving cavity 112 can also be divided by a baffle to form a first area and a second area, wherein the first area is used to store batteries to be charged and the second area is used to store batteries that have been fully charged, so as to facilitate operation by operators. Alternatively, there can be multiple second receiving cavities 112, which can be arranged vertically along the height direction of the main body 1 and / or horizontally along the width direction of the main body 1, and can be used to separately store batteries to be charged and batteries that have been fully charged.

[0050] In some implementations, reference Figure 1 As shown, the main body 1 includes a switch door 12, which is used to openably close the accommodating space 11 in order to maintain the temperature of the accommodating space 11. In addition, it can also be used to isolate possible fire and reduce the possibility of battery loss.

[0051] It is understood that the main body 1 may also include at least one of a display screen 13, a temperature indicator 14, and a buzzer 15 located above and / or to the side of the door 12. The display screen 13 may be used to display the battery charging status, for example, the battery charging completion status corresponding to each battery compartment 2; the temperature indicator 14 may be used to display the temperature of the accommodating space 11 as a reference for the air conditioning system 3; and the buzzer 15 may be used to issue an alarm in the event of battery thermal runaway.

[0052] In addition, the charging device may also include a shield 16, wherein the shield 16 is mounted above the main body 1 to at least shield the main body 1 from top to bottom. In this way, the shield 16 can reduce the damage to the main body 1 caused by environmental factors such as sunlight and rain, and extend the service life of the main body 1.

[0053] In some implementations, reference Figure 1 As shown, the charging device also includes a camera 17, which is connected to the shield 16 or the main body 1. The camera 17 allows operators to remotely monitor the safety of the charging device, such as monitoring for fires caused by battery thermal runaway. Furthermore, the camera 17 can also be used for anti-theft measures on the charging device and the battery.

[0054] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
