Since the batteries in the battery pack will generate a lot of heat during operation, the performance of the battery pack will be severely affected. As a result, new energy vehicles are increasingly being developed with a focus on enhancing the rapid and uniform heat dissipation of the battery pack during charging and discharging.
The heat generation in various self-heating technologies and the duration of heating are influenced by the battery SOC and SOH, given the variation in the battery’s impedance with SOC and SOH , , . The impedance of batteries with different power densities (Eρ) typically experiences fluctuations .
As the rate of charge or discharge increases, the battery generates more heat energy. The battery's efficiency and longevity are negatively impacted by excessive heat. In cylindrical Li-ion batteries, the highest heat generation typically occurs at the center of the axis and then radiates outward to the cylinder's surface.
The integration of advanced heat dissipation technologies, such as heat pipe cooling plates, remote heat transfer heat pipes, and liquid-cooled cold plates, presents a promising solution for efficiently managing the thermal challenges posed by high-power battery modules.
Most of these problems are caused by damage to the internal structure of the battery, and the main reason for the problem is that the battery thermal management system does not monitor and equalize in time.
