Resistance preheating technique is low in price, but other indicators are poor. Although the direct conduction of the resistance shortens the heat transfer path, it is exposed to the air and loses a lot of heat. In addition, in practical application, this method is also limited by the shape of the battery.
Air and liquid preheating techniques can not only heat but also cool the battery systems because it can be combined with the temperature management system. At present, air preheating techniques have been commercialized by Honda and Toyota, and liquid preheating techniques have been commercialized by Tesla and Volt.
The authors applied sinusoidal alternating polarization voltage (SAPV) to preheat the batteries. The battery can be heated from −15.4 °C to 5.6 °C within 338 s with an essentially uniform temperature distribution. Besides, R. Xiong et al. presented a novel echelon internal heating strategy.
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.

Therefore, the above research results further validate the effectiveness and battery-friendliness of the AC preheating method. A temperature-adaptive, deposition-free AC preheating method was proposed by combining the maximum allowable AC current and the heat generation rate model in the frequency domain by H. Ge et al. .
