The main challenge in battery heating is accurately simulating and predicting the heat distribution inside the battery. However, there is little literature on the model simulation to accurately reflect the internal heat distribution of the battery and the impact of the AC device on the battery life.
In summary, the heating strategy offers advantages such as uniform heat generation, fast heating speed, simple control, low cost, and independence from battery shape. Using high-frequency AC to charge or discharge LIB can effectively address the issue of battery aging due to voltage imbalances.
