The proposed rapid preheating system and improved battery charging architecture can shorten the charging time and reduce energy consumption. This advancement will open up new possibilities for power battery protection and contribute to the development of lithium-ion batteries for electric vehicles at low temperatures. 1. Introduction
Thus, thermal management of the Battery system is critical, so that necessary cooling is provided to reduce the temperature rise in Battery during its operation, which will increase the longevity of the Battery. This will in turn improve the overall efficiency of the vehicle, affecting the performance and the range of the vehicle.
The growth of lithium dendrites will impale the diaphragm, resulting in a short circuit inside the battery, which promotes the thermal runaway (TR) risk. Hence, it is essential to preheat power batteries rapidly and uniformly in extremely low-temperature climates.
Battery preheating techniques can be categorized into internal and external heating, according to whether the heat source is inside or outside battery cell . Internal heating techniques, including self-heating and current excitation heating, are commonly performed in laboratory settings.
The battery rapid preheating control strategy has been redesigned to rapidly heat the battery system by disconnecting the rapid charging relay of the high-voltage circuit, thereby prevents over-discharge and overcharge of the power battery.
