Abstract:
A battery charging system includes a charging source, at least one battery cell, a battery internal temperature sensor configured to measure an internal temperature of the at least one battery cell responsive to charging of the at least one battery cell by the charging source, and a charge controller. The charge controller is configured to receive indications of the internal temperature of the at least one battery cell over time, to identify an indication that the at least one battery cell is at a point of full charge based on rate of change of the internal temperature, and to interrupt power delivery from the charging source to the at least one battery cell responsive to the indication that the at least one battery cell is at the point of full charge.
