[0027] The following is for reference. Figure 1 A battery discharge device 100 according to an embodiment of the present invention is described.

[0028] This battery discharge device 100 is used for rapid battery discharge.

[0029] The battery discharge device 100 includes a support platform 10 and a discharge assembly 20. The support platform 10 has a cavity 112 for holding coolant. The coolant helps to cool the battery during discharge and prevents overheating.

[0030] A cavity 112 is provided on the battery discharge device 100 to hold coolant, which continuously cools the discharge process, improves heat dissipation efficiency, and helps to shorten the battery discharge time.

[0031] The support platform 10 is provided with a battery placement area 130 for placing batteries. The battery placement area 130 is used to fix the batteries, ensuring their stability during the discharge process and preventing the discharge efficiency from being affected by shaking or poor contact during the discharge process.

[0032] The discharge assembly 20 includes a heating resistor 22 and two conductive parts 24 connected to the heating resistor 22. The heating resistor 22 is located inside the cavity 112, and the two conductive parts 24 are used to connect the two electrodes of the battery.

[0033] Here, the heating resistor 22 is located inside the cavity 112 of the support platform 10 and is surrounded by coolant to continuously dissipate heat when the battery is discharging.

[0034] The two conductive parts 24 are used to connect to the positive and negative electrodes of the battery to ensure that current can pass through.

[0035] Specifically, when the battery begins to release heat, current flows through the conductive element 24 into the heating resistor 22. At this time, the heating resistor 22 generates heat, and the surrounding coolant cools the heating resistor 22 in a timely manner, maintaining the operational stability of the battery discharge device 100.

[0036] Optionally, the heating resistor 22 comprises a nickel-chromium alloy wire.

[0037] First, nickel-chromium alloys have stable resistivity, maintaining a relatively constant resistivity even under temperature variations. This characteristic helps ensure stable current during discharge, improving the safety and efficiency of the entire discharge process.

[0038] Secondly, using nickel-chromium alloy wire as the heating element allows for the use of waste materials from lithium battery production, promoting resource recycling, reducing environmental pollution, and helping to lower production costs, thus achieving green and environmentally friendly practices.

[0039] According to some alternative embodiments of the battery discharge device 100, the support platform 10 includes a housing 11 and a tray 13, with a cavity 112 formed within the housing 11. The tray 13 is connected to the housing 11 and has a battery placement area 130 on it.

[0040] It is worth mentioning that the housing 11 and tray 13 can be made from waste materials generated during the lithium battery production process, achieving resource recycling. This helps reduce the cost of manufacturing new components and also improves the resource recycling rate, reduces environmental impact, and achieves green environmental protection.

[0041] Alternatively, both the housing 11 and the tray 13 may be made of insulating material.

[0042] In some alternative embodiments, the top of the housing 11 is provided with a housing opening 113, and the trays 13 are at least one set, each set of trays 13 including two and located on opposite sides of the housing opening 113, so as to place the battery across the housing opening 113.

[0043] This arrangement creates a vertically layered structure of housing 11-tray 13-battery, placing the battery on the upper layer of the battery discharge device 100 for easy placement and retrieval, thus improving operational efficiency and safety. Placing housing 11 on the lower layer of the battery discharge device 100 optimizes the heat dissipation path.

[0044] In some further alternative embodiments of the battery discharge device 100, the support platform 10 also includes: rollers 15 disposed at the bottom of the housing 11.

[0045] The presence of rollers 15 allows the battery discharge device 100 to be moved, facilitating flexible adjustment of its position as needed. This improves operational convenience and enhances the device's adaptability.

[0046] Alternatively, the roller 15 may have a locking function. This ensures that the device remains stable during use and that accidental movement will not affect the discharge process, thus improving the safety of the battery discharge device 100.

[0047] In some specific embodiments, the bottom of the housing 11 is provided with a drain port 114. The drain port 114 is used to quickly drain the coolant.

[0048] The drain port 114 is located at the bottom of the housing 11, which allows for easy drainage without affecting the operation of other parts of the battery discharge device 100, thus ensuring the effectiveness of the cooling system.

[0049] According to some optional embodiments, the support platform 10 further includes support feet 17 disposed at the bottom of the housing 11. The support feet 17 are used to support the battery discharge device 100, keeping it stable as a whole, and ensuring that the device will not tilt or shift due to uneven ground or vibration during operation.

[0050] Optionally, the height of the support foot 17 is adjustable. In this way, the support foot 17 can be used in conjunction with the roller 15. When a fixed position is required, the support foot 17 can be raised to stably fix the battery protection device on the ground, enhancing the safety and reliability of operation. When movement is required, the support foot 17 can be lowered to detach from the bottom surface, making the roller 15 the main contact point, thus enabling flexible movement of the device.

[0051] In addition, the height-adjustable support feet 17 can adapt to different ground conditions to improve the applicability of the battery discharge device 100.

[0052] In some alternative embodiments, the tray 13 includes a base block 131 and two card plates 132 disposed on the base block 131, the two card plates 132 being spaced apart and defining a battery placement area 130 above the base block 131 and between the two card plates 132.

[0053] By using two card plates 132 and the block to limit the battery, it can be ensured that the battery is fixed in a designated position during discharge, reducing possible displacement and other issues.

[0054] This design also facilitates battery placement and retrieval. When placing the battery, the operator simply aligns it with the gap between the two clips 132 and pushes it in to complete the positioning. Similarly, when retrieving the battery, simply lift it upwards to quickly remove it. The entire process is simple, quick, and easy to operate.

[0055] Optionally, the conductive element 24 includes a discharge clip 241 and a wire 242, wherein the discharge clip 241 is used to clamp onto the electrodes of the battery to ensure the stability of the electrical connection.

[0056] One end of the wire 242 is connected to the discharge clamp 241, and the other end is connected to the heating resistor 22, thus forming a complete discharge circuit.

[0057] This design results in a simple structure that is easy to assemble and maintain, and also reduces manufacturing costs. Furthermore, this connection method is direct and reliable, reducing the need for complex components and making the overall device more economical and practical.

[0058] According to some optional embodiments of the present invention, the battery discharge device 100 has a heating resistor 22 that is a columnar body formed by multiple strands of conductive wires.

[0059] This configuration increases the conductive cross-sectional area, enhances the current carrying capacity, and ensures stability during high-current discharge.

[0060] Meanwhile, the larger conductive cross-sectional area and columnar structure help heat to be conducted to the coolant more quickly, improving heat dissipation efficiency.

[0061] Alternatively, the heating resistor 22 may be composed of multiple nickel-chromium alloy wires. This results in a low resistance and high heat generation for the heating resistor 22, which is beneficial for discharge.

[0062] More optimally, the battery discharge device 100 also includes a copper conduit for connecting the wire 242 to the heating resistor 22.

[0063] The battery discharge device 100 according to some optional embodiments of the present invention further includes: a series assembly for connecting two batteries in series.

[0064] By connecting them in series, the overall discharge voltage can be increased, allowing for a larger current to flow. Here, the heating resistor 22 should preferably be a resistor with a relatively high resistance value.

[0065] Optionally, the series assembly also includes a connecting wire and electrical clamps at both ends of the connecting wire, which facilitates the series connection between the two batteries and simplifies the operation.

[0066] In some alternative embodiments, a through hole 115 is provided on the side wall of the housing 11. A wire 242 passes through the through hole 115 and is connected to the heating resistor 22.

[0067] The following is for reference. Figure 1 The battery discharge device 100 according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0068] The battery discharge device 100 includes a support platform 10 and a discharge assembly 20.

[0069] The support platform 10 includes: a housing 11, a tray 13, rollers 15, and support feet 17. The housing 11 has a cavity 112, an opening 113 at the top, a drain outlet 114 at the bottom, and through holes 115 on its side walls. The rollers 15 and support feet 17 are located at the bottom of the housing 11.

[0070] The trays 13 are in at least one set, and each set of trays 13 includes two trays located on opposite sides of the opening 113 to place the batteries across the opening 113.

[0071] The tray 13 includes a base block 131 and two card plates 132 disposed on the base block 131. The two card plates 132 are spaced apart and define a battery placement area 130 above the base block 131 and between the two card plates 132.

[0072] The discharge assembly 20 includes a heating resistor 22 and two conductive parts 24 connected to the heating resistor 22. The heating resistor 22 is located inside the cavity 112, and the two conductive parts 24 are used to connect the two electrodes of the battery.

[0073] The conductive component 24 includes a discharge clip 241 and a wire 242. The discharge clip 241 is used to clamp onto the electrode of the battery. One end of the wire 242 is connected to the discharge clip 241, and the other end passes through the through hole 115 and is connected to the heating resistor 22.

[0074] The heating resistor 22 is a columnar body formed by multiple strands of conductive wire.

[0075] The battery discharge device 100 according to the present invention has advantages such as simple structure, high heat dissipation efficiency, cost saving and simple operation.

[0076] In existing technologies, discharge methods also include physical discharge through a detection cabinet or chemical discharge using salt water immersion. A comparison is provided here with reference to Table 1:
