In this study, a method was developed to internally preheat lithium-ion batteries at low temperature using a sinusoidal alternating current. A model in the frequency domain was developed to simulate the heat generation rate based on the EEC.
Alternating current (AC) is capable of heating up a lithium-ion battery efficiently before charging at low temperature. Generally, the lower the frequency of the AC current, the higher the heat generation rate. Yet at low frequency, there is a risk of lithium-ion deposition during the half cycle of charging.
However, the influence of AC preheating current on the degradation of lithium-ion batteries is still unclear. The authors' group has been working on the degradation mechanisms of lithium-ion batteries and these work could provide more constraints for the selection of preheating current parameters.
The preheating current parameters are adaptive with the cell temperature to achieve a higher heat generation rate with lithium deposition prevention. The proposed AC internal preheating method can be used to preheat lithium-ion batteries at low temperatures with high energy efficiency and uniform temperature distribution.

Lithium-ion battery degradation mechanisms at low temperatures. Preheating methods for lithium-ion batteries can be categorized into external heating and internal heating, according to the heat transfer process. The external heating technique is generally realized by the battery thermal management system (BTMS) or electrothermal element.

The primary aging mechanisms of lithium-ion batteries are lithium plating and SEI growth [67], [68]. SEI grows rapidly at the beginning of the life cycle and gradually slows from 5 to 50 °C. The capacity loss caused by SEI growth is increased with temperature, causing the aging rate to increase at temperatures higher than 20 °C.

Do not charge lithium ion batteries below 32°F/0°C. In other words, never charge a lithium ion battery that is below freezing. Doing so even once will result in a sudden, severe, and permanent capacity loss on the order of several dozen percent or more, as well a similar and also permanent increase in internal resistance.
The significant decrease in battery performance at low temperatures is one of the critical challenges that electric vehicles (EVs) face, thereby affecting the penetration rate in cold regions. Alternating current (AC) heating has attracted widespread attention due to its low energy consumption and uniform heating advantages.
