The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
For the embedded heating elements, Wang et al. embedded nickel foil inside the battery and utilized the heat generated by the nickel foil to heat the battery. Although this method can heat the battery from −20 °C to 0 °C in 20 s, it requires a redesign of the battery structure and the effect on battery safety is not clear.
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 .
The battery heats the evaporation section of the heat pipe, and the liquid inside the pipe core evaporates to steam as a result. During condensing, the steam releases latent heat and returns to liquid, which passes through the central channel of the heat pipe.
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.
During the resting phase following the battery heating, the battery temperature gradually decreases to the ambient temperature Tam. Throughout this process, the heating power q of the battery is zero. The variation in the battery temperature can be delineated based on the modification of Eq.
