Ruan et al. constructed a low-temperature composite self-heating system, as shown in Fig. 46. This system integrated the internal DC heating of the battery and the external electromagnetic heating of the battery to improve the heating rate and efficiency without the need for an additional power supply.
Internal heating methods achieve self-heating by taking advantage of the high internal resistance of the LIB at low temperatures to generate heat during the charge/discharge process . Internal heating can be divided into two types: internal heating with an external current and self-discharge heating.
Current heating strategy primarily involves external and internal heating. External heating refers to the process of preheating through convection and conduction by setting up an additional heat source outside the battery, typically including air, liquid, phase-change material (PCM) and heat pipe [, , , , , ].
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.
The internal heating method utilizes the Joule heat generated by current passing through a conductor with a certain resistance value to heat the power battery, with the conductor being the power battery itself.
