ABSTRACT:
Disclosed is a device and method for charging an electric car battery pack that charges by receiving power and discharges to supply power. A battery charging controller controls charging the battery pack at a constant power, and when the voltage of the battery pack is over a first voltage, controls a constant current charging process, and after this, each time a peak value of the battery pack is over a second voltage, controls a sequential reduction of current and performs a constant current charging process, and when the voltage of the battery pack is over a third voltage, controls a constant current charging process at a fourth voltage, and when the charging voltage is over a fifth voltage, controls a termination of the charging process. A battery charger receives external power according to the control of the battery charging controller, and charges the battery.
