ABSTRACT:
A battery identification system (100) includes a battery (104), a device (102), and an apparatus (106). The battery (104) is of a particular type (e.g., NiCd, NiMH, Lithium Ion) and is detachably coupled to the device (102). The device (102) includes a controller (112) that determines the type of the battery (104) and generates a number of signals according to the type. The apparatus (106) is detachably coupled to the device (102) and includes a current source (164) and a controller (162) that detects the number of signals. The controller (162), responsive to the controller (112), controls the current source (164) to initially provide charging current at a first rate to the battery (104) until reception of a first one of the number of signals. The controller (162) thereafter identifies the type of the battery (104) from the detection of additional ones of the number of signals.
