Charging device for commonly charging various kinds of battery

摘要

A charging device for commonly charging various kinds of batteries is provided. The charging device includes a switching portion controlled to interrupt the supply of power to the charging device and a plurality of charging paths located between a charging power supply port and the battery's charging port, corresponding to the kinds of battery. A charging voltage detector detects a predetermined voltage or current formed when connected to the first sensing resistor of a battery assembly in order to detect the charged voltage of the battery and a capacity detector detects a predetermined voltage or current formed when connected to the second sensing resistor of the battery assembly in order to detect the charged capacity of the battery. A main controller determines the kind of battery and selects a corresponding charging path according to the voltage and current value respectively detected from the charging voltage detector and capacity detector so as to allow the selected charging path to be connected to the battery's charging port.
