[0002] With the rapid development of electric vehicles, drones, portable electronic devices and other fields, efficient and reliable battery charging technology has become increasingly important. Traditional battery charging methods often involve complex cable connections and fixtures, which not only increase the difficulty of operation, but may also lead to low charging efficiency or safety hazards due to poor contact. In the existing technology, although there have been some attempts to simplify the installation and removal process of battery packs through mechanical locks, magnetic suction and other methods, these solutions often ignore the flexibility and reliability of the connection between the battery cell pole and the battery pack. For example, the fixed battery cell pole design may not be able to achieve perfect docking due to slight differences in the size or position of the battery pack. It has poor versatility and cannot be used for batteries of different sizes and specifications, which in turn affects the charging efficiency and battery life. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0024] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0025] In an embodiment of the present invention, this case provides a battery charging quick connection device for connecting a charging and discharging device (not specified) to a battery pack (not specified), comprising an upper support plate 100 on which the charging and discharging device is mounted, a lower support plate 110 on which the battery pack is mounted, and two battery poles 120, which are divided into positive and negative poles. The upper support plate 100 and the lower support plate 110 are detachably connected, and a cavity 130 is provided between the two, and the battery pack is located in the cavity 130. The upper support plate 100 is also provided with two parallel empty slots 140. One end of the two battery poles 120 is electrically connected to the charging and discharging device, and the other end passes through the empty slots 140 and is electrically connected to the battery pack. The battery poles 120 can move laterally in the empty slots 140, that is, the charging and discharging device and the battery poles 120 are connected by a wire, and the length of the wire allows the battery poles 120 to move laterally left and right in the empty slots 140. The battery poles 120 are used to separately connect the voltage part and the current part of the battery pack.

[0026] Specifically, the battery charging quick connection device is used for thermal diffusion testing of energy storage battery packs, and charges the single cells in the battery pack without destroying the high-voltage connection of the battery pack. First, ensure that the upper tray 100 is separated from the lower tray 110, and place the battery pack correctly on the lower tray 110. Align the upper tray 100 with the lower tray 110 and slowly close them until the two are locked. During this process, the position of the battery cell pole 120 in the empty slot 140 is adjustable, that is, the charging and discharging equipment and the battery cell pole 120 are connected by a wire, and the length of the wire allows the battery cell pole 120 to move horizontally left and right in the empty slot 140 to ensure precise docking with the battery pack electrode to suit battery packs of different specifications. Start the charging and discharging equipment, the voltage and current are separated and transmitted to the battery pack through the battery cell pole 120 for charging.

[0027] In another embodiment of the utility model, a spring 150 is connected to the battery cell pole 120, and the other end of the spring 150 is connected to a pin 160 located in the battery cell pole 120, and the pin 160 always passes through the battery cell pole 120. The elastic force causes the pin 160 to extend or retract in the battery cell pole 120; the pin 160 is connected to the voltage part of the battery pack, and the bottom of the battery cell pole 120 is connected to the current part of the battery pack. Specifically, in terms of the traditional connection between the battery pack and the charging and discharging equipment, the voltage line and the current line share a terminal, and the voltage collection accuracy is poor. The voltage connection port and the current connection port of the battery charging quick connection device are separated, so that the voltage line and the current line of the battery pack contact the battery pole separately, ensuring voltage accuracy.

[0028] In another embodiment of the utility model, two layers of outwardly protruding rings 170 are provided on the outer side wall of the battery cell pole 120, and the two rings 170 are respectively abutted against the upper end and the lower end of the upper support plate 100, and the diameter of the two rings 170 is larger than the width of the empty groove 140, so as to limit the battery cell pole 120 from separating from the upper support plate 100, thereby improving stability.

[0029] In another embodiment of the utility model, a plurality of clamping members 180 are provided on the upper support plate 100. The clamping members 180 include two symmetrically arranged clamping plates 190. The two clamping plates 190 are respectively fixed to the upper and lower ends of the upper support plate 100. A locking member passes through the clamping plates 190 and the upper support plate 100 from top to bottom. The outermost ends of the two fixing plates are provided with an oblique portion 200 for scratch protection. When the charging and discharging equipment is pressed downward with force, the two middle battery poles 120 will be supported. Applying pressure may cause the upper support plate 100 to deform. By locking the upper and lower fixing plates with screws, the pressing force between the channel terminal and the battery pole 120 is increased, preventing the upper support plate 100 from deformation and reducing contact resistance.

[0030] In another embodiment of the utility model, a first connection port 210 is provided at the end of the upper support plate 100, and a second connection port 220 is provided at a corresponding position on the lower support plate 110. A first locking member (not shown) passes through the first connection port 210 and the second connection port 220 from top to bottom to lock the upper support plate 100 and the lower support plate 110. A third connection port 230 is also provided at the end of the upper support plate 100, and a fourth connection port 250 is provided at a corresponding position on the lower support plate 110. A second locking member (not shown) passes through the first connection port 210 and the second connection port 220 from top to bottom to lock the upper support plate 100 and the lower support plate 110. The double locking member design makes the connection between the upper support plate 100 and the lower support plate 110 more secure and stable, and can maintain a good connection even in a vibrating or bumpy environment.

[0031] In another embodiment of the utility model, the upper support plate 100 is made of bakelite. As an excellent insulating material, bakelite has high electrical strength and dielectric strength, effectively isolating current and electric fields. This prevents leakage during operation of the charging and discharging device, which could lead to damage.

[0032] In another embodiment of the utility model, the lower supporting plate 110 is made of stainless steel.

[0033] In another embodiment of the utility model, the battery cell pole 120 is made of red copper. It has good electrical and thermal conductivity, excellent plasticity, and is easy to be processed by hot pressing and cold pressing. It is widely used in the manufacture of products requiring good electrical conductivity, such as wires and terminals.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
