Number of charging stages and the associated transition conditions are adaptive. A trade-off between charging time and battery aging at low temperatures is achieved.
However, due to the large latent heat of PCM, the temperature of the initial stage of the battery increased slowly in a cold environment. Additionally, the larger thermal mass of the PCM prevented the cell from self-heating during long-term application in low temperatures, resulting in a loss of power and capacity.
There is a need to propose a suitable cooling strategy considering the target energy density of the EV battery which is expected to be attained in the future.
