Description

Technical Field

[0001] This utility model relates to the field of charging rack technology, specifically a battery swapping station charging rack with a liquid-cooled plate that can be controlled independently. Background Technology

[0002] In recent years, the rapid development of electric vehicles has shaken the traditional energy industry. Traditional charging methods often cause inconvenience to users due to long charging times, while battery swapping provides a convenient solution. Users can complete a battery replacement in just a few minutes without affecting their travel plans. Battery swapping technology is gradually becoming an important trend for future travel. Battery swapping for new energy vehicles needs to be carried out inside a battery swapping station, which typically contains multiple charging racks.

[0003] Currently, when battery swapping racks charge and discharge car batteries, the surface temperature of the car battery rises due to internal resistance, heat generated by chemical reactions, and energy loss. To prevent thermal runaway of the swapped battery, liquid cooling plates are usually used to cool it down. Existing battery swapping racks generally have multiple swapping chambers, each equipped with a liquid cooling plate. Existing liquid cooling units generally control all liquid cooling plates collectively, resulting in some liquid cooling plates in swapping chambers that do not contain swapped batteries also operating, leading to unnecessary energy loss. Utility Model Content

[0004] The purpose of this invention is to provide a battery swapping station charging rack with individually controllable liquid-cooled plates, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery swapping station charging rack with individually controllable liquid-cooled plates, comprising a charging rack body, wherein multiple battery swapping chambers are provided inside the charging rack body, and a liquid-cooled plate body is movably installed inside each battery swapping chamber. A liquid-cooling unit is installed above the charging rack body, and a pump body is installed inside the liquid-cooling unit. A diversion pipe and a return pipe are respectively installed on the liquid-cooling unit, and the diversion pipe and the return pipe are connected to the liquid-cooled plate body through branch pipes. An electric control valve is installed on the surface of each branch pipe on the diversion pipe.

[0006] Preferably, mounting plates are installed on both sides of the battery swapping cavity, and several guide wheels are installed on the opposite sides of the two mounting plates.

[0007] Preferably, a base plate is installed at the bottom of each battery swapping chamber, an inflatable airbag is placed on top of the base plate, and the liquid cooling plate body is placed on the upper surface of the inflatable airbag.

[0008] Preferably, two sleeves are installed at the upper end of the base plate, and the upper end of the sleeves passes through the inflatable airbag through a through hole. Two guide posts are installed at the lower end of the liquid cooling plate body, and the guide posts are slidably installed inside the sleeves.

[0009] Preferably, one-way flow valves are installed on the surface of each branch pipe on the return pipe.

[0010] Preferably, a thermal runaway chamber is provided inside the charging rack body below the bottommost battery swapping chamber, and a fire sandbox is placed at the rear of the thermal runaway chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This liquid-cooled plate can be individually controlled in the battery swapping station charging rack. By using multiple electric control valves to control the on / off of the branch pipes on the drain pipe, when the battery inside the swapping chamber is not being charged or discharged, the heat exchange medium will not enter the corresponding liquid-cooled plate, thus achieving cooling only for the battery being charged or discharged, effectively reducing energy loss.

[0013] 2. This liquid-cooled plate can be independently controlled in the battery swapping station charging rack. By using an inflatable airbag to move the liquid-cooled plate up and down, the liquid-cooled plate will not contact the bottom of the battery when the battery is placed into the swapping chamber or removed from the swapping chamber. This effectively avoids scratches on the surface of the liquid-cooled plate when the battery is moved, and effectively extends the service life of the liquid-cooled plate.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4 As shown, this embodiment of the battery swapping station charging rack with independently controllable liquid-cooled plates includes a charging rack body 1. The charging rack body 1 houses a charging / discharging power module and a charging / discharging interface. When a battery is placed inside a swapping cavity 2, the battery is connected to the charging / discharging interface. The charging rack body 1 has multiple swapping cavities 2 for placing the batteries. A liquid-cooled plate body 3 is movably installed inside each swapping cavity 2. A liquid-cooling unit 4 is installed above the charging rack body 1 and connected to the liquid-cooled plate body 3. A pump is installed inside the liquid-cooling unit 4, which injects a heat exchange medium into the liquid-cooled plate body 3. The heat exchange medium cools the battery through the liquid-cooled plate body 3. The specific working principle of the liquid-cooling unit 4 is as follows. Since the technology is known and therefore will not be described in detail, the liquid cooling unit 4 is equipped with a drain pipe 5 and a return pipe 6. The drain pipe 5 injects the heat exchange medium into the liquid cooling plate body 3, and the return pipe 6 is used to return the heat exchange medium flowing out of the liquid cooling plate body 3 back into the liquid cooling unit 4 for processing. Both the drain pipe 5 and the return pipe 6 are connected to the liquid cooling plate body 3 through branch pipes 7. Electric control valves 8 are installed on the surface of the branch pipes 7 on the drain pipe 5. By using multiple electric control valves 8 to control the opening and closing of the branch pipes 7 on the drain pipe 5, when the battery in the battery swapping chamber 2 is not being charged or discharged, the heat exchange medium will not enter the corresponding liquid cooling plate body 3, thus achieving cooling only for the charged and discharged battery and effectively reducing energy loss.

[0022] Specifically, mounting plates 9 are installed on both sides of the battery swapping chamber 2. Several guide wheels 10 are installed on the opposite sides of the two mounting plates 9. The guide wheels 10 are used to support the two ends of the battery swapping chamber, making it easier to put the battery swapping chamber into the battery swapping chamber 2 and take it out of the battery swapping chamber 2.

[0023] Furthermore, a base plate 11 is installed at the bottom of the battery swapping chamber 2. An inflatable airbag 12 is placed on top of the base plate 11, and the liquid cooling plate body 3 is placed on the upper surface of the inflatable airbag 12. The inflatable airbag 12 is connected to an inflation / deflation device. The inflation / deflation device inflates the inflatable airbag 12, causing it to expand and lift up along with the liquid cooling plate body 3, so that the liquid cooling plate body 3 contacts the bottom of the battery swapping chamber. Conversely, the inflation / deflation device deflates the inflatable airbag 12, causing the inflatable airbag 12 to lift the liquid cooling plate body 3, so that the liquid cooling plate body 3 does not contact the battery swapping chamber. When the battery swapping chamber 2 is entered and removed from the battery swapping chamber 2, the liquid cooling plate body 3 does not contact the battery swapping chamber, thus avoiding scratches on the surface of the liquid cooling plate body 3 when the battery swapping chamber is moved.

[0024] Furthermore, two sleeves 13 are installed on the upper end of the base plate 11. The upper end of the sleeves 13 passes through the inflatable airbag 12 through the through hole. Two guide posts 14 are installed on the lower end of the liquid cooling plate body 3. The guide posts 14 are slidably installed inside the sleeves 13. When the inflatable airbag 12 drives the liquid cooling plate body 3 to rise and fall, the liquid cooling plate body 3 drives the guide posts 14 to move inside the sleeves 13, which plays a guiding role in the rise and fall of the liquid cooling plate body 3.

[0025] Furthermore, one-way flow valves are installed on the surface of the branch pipes 7 on the return pipe 6. The heat exchange medium entering the liquid cooling plate body 3 enters the return pipe 6 through the branch pipes 7 on the return pipe 6 and flows back into the return pipe 6. The one-way flow valves prevent the heat exchange medium inside the return pipe 6 from entering the liquid cooling plate body 3 through the branch pipes 7.

[0026] Furthermore, a thermal runaway chamber 15 is provided inside the charging rack body 1 below the bottom battery swapping chamber 2. A fire sandbox 16 is placed at the rear of the thermal runaway chamber 15. By placing the battery that has caused thermal runaway into the thermal runaway chamber 15, the battery that has entered the thermal runaway chamber 15 can be placed into the fire sandbox 16, making it easier to deal with the thermal runaway battery and avoid affecting the other batteries.

[0027] The usage method of this embodiment is as follows: When in use, the battery swapping device enters the battery swapping chamber 2 through the guide wheel 10. The battery swapping device is connected to the charging and discharging power module through the interface. When charging and discharging the battery swapping device, the charging and discharging device inflates the airbag 12. The airbag 12 expands and drives the liquid cooling plate body 3 to rise. The liquid cooling plate body 3 contacts the bottom of the battery swapping device. At the same time, the electric control valve 8 on the corresponding branch pipe 7 on the liquid cooling plate body 3 opens, and the liquid cooling unit 4 starts to work. The heat exchange medium enters the liquid cooling plate body 3 through the diversion pipe 5 and its branch pipe 7. The heat exchange medium cools the surface of the battery swapping device through the liquid cooling plate body 3. The heat exchange medium after absorbing heat returns to the liquid cooling unit 4 through the branch pipe 7 on the return pipe 6 and the return pipe 6 for processing. When the battery swapping device finishes charging and discharging, the electric control valve 8 closes, the liquid cooling unit 4 stops working, and the charging and discharging device deflates the airbag 12, so that the liquid cooling plate body 3 descends and no longer contacts the battery swapping device.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
