Description

Technical Field

[0001] This utility model relates to the field of battery fast charging technology, specifically to a liquid-cooled fast charging battery thermal management module. Background Technology

[0002] A fast-charging battery module is a battery module specifically designed to achieve fast charging. It typically consists of multiple battery cells, a battery management system (BMS), a thermal management system, and battery protection circuits. By employing advanced charging technology and optimized battery structure, fast-charging battery modules enable the battery to be charged in a shorter time, improving charging efficiency. Compared to traditional battery modules, fast-charging battery modules usually have higher power density and can receive and release more electrical energy in a shorter time, thereby significantly shortening the charging cycle.

[0003] While existing traditional fast-charging battery modules can achieve fast charging speeds, the battery generates high temperatures during rapid charging. Excessive temperatures not only affect charging efficiency but can also accelerate battery aging, potentially leading to damage or safety hazards. High temperatures negatively impact the stability of internal chemical reactions, shortening battery lifespan. Furthermore, excessive temperatures can cause battery swelling, leakage, and in severe cases, short circuits or fires. As charging speeds continue to increase, traditional air cooling technology is insufficient to meet the demands of heat control, preventing the battery from maintaining a safe temperature range during fast charging. This inadequate temperature control negatively impacts battery performance.

[0024] This liquid-cooled fast-charging battery thermal management module, through precise heat conduction and heat dissipation design, can efficiently control the battery temperature during fast charging, ensuring that the battery operates within a safe temperature range. The battery charging component 1 guides the heat generated by the battery body 5 to the heat-conducting copper pipe 204 through the heat-conducting component 2, and further transfers the heat to the heat dissipation component 4 through the heat conduction component 3. The flow of liquid in the heat-conducting copper pipe 204 carries away the heat, ensuring that heat does not accumulate inside the battery or system, thereby avoiding excessive rise in battery temperature. The heat dissipation component 4 uses heat dissipation fins 401 and cooling fan 402 to quickly dissipate heat to the external environment, enhancing the heat dissipation effect.

During battery charging, heat inside the battery is conducted from the lower heat-spreading plate 201 to the upper heat-spreading plate 202, and then transferred to the external heat dissipation device through the heat-conducting copper pipe 204. The high thermal conductivity of the copper pipe allows heat to be distributed quickly and evenly, ensuring that heat does not accumulate locally. The heat-conducting component 2 plays a core role in the entire battery charging process, ensuring the balance and stability of the battery temperature during charging.
