摘要 |
A battery charging system (10) includes a charging path (50) for charging batteries (14) which have a variety of different charging parameters requiring different optimum charging algorithms (58). The battery charging system (10) comprises a charging algorithm sensing circuit (30). At least one battery cell (14A, 14B) having a positive (23) and a negative terminal (27) and an optimum charging algorithm is to be charged. An impedance (R18) having two terminals and a value related to a predetermined charging algorithm of the cell approximating the optimum charging algorithm is coupled to one of the positive or negative terminals of the battery cell (14B). A capacitor (C72) combines with the impedance (R18) to form a characteristic related to the predetermined charging algorithm. Battery terminals (23 and 27) connected to the cell (14A and 14B) and to one of the terminals of the impedance (R18) form a battery (12) for connecting the cell (14A-B) into the battery charging system (10) with the cell (14A-B) in the charging path (50), and the impedance (R18) and the capacitor (C72) in the charging algorithm sensing circuit.
