1. A battery charging system comprising:

  • a charging source; and

    at least one battery cell;

    a battery internal temperature sensor configured to measure an internal temperature directly, and without the use of mathematical model or mathematical algorithm, 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 configured to;

    receive indications of the internal temperature of the at least one battery cell over time,identify an indication that the at least one battery cell is at a point of full charge based on changes in the internal temperature, andinterrupt 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.
