Abstract: PURPOSE: A battery pack charging apparatus and a method are provided to enhance stability by using a relation between a charging current and a charging voltage to monitor each module state in real time. CONSTITUTION: A battery pack charging apparatus for electric vehicle comprises a battery charge controlling unit(10), a charging unit(20) and a battery pack(30). In a battery discharging mode, a user turns on a switch(S). The battery charge controlling unit(10) detects the initial charge state of the battery pack(30) and controls the battery pack(30) to start the charging. If a battery pack voltage is over first predetermined voltage in charging the battery pack(30), a constant current charging is performed. Then, whenever the battery pack voltage is over second predetermined voltage, a constant current charging is performed while sequentially reducing the current. If the battery pack voltage is over third predetermined voltage, a constant voltage charging is performed, and if the charging voltage is over the fifth voltage, the charging is terminated. An erroneous operation of the battery pack(30) can be prevented and stability can be enhanced.
