Abstract
A safety charging system includes: a motor and an inverter which boost a voltage charged from a high-speed battery charger to a high voltage battery; a current variation amount sensor configured to detect variation amount of a current flowing in a motor coil from the high-speed battery charger; and a controller configured to determine that a rotor of the motor rotates when the variation amount of the current detected in the current variation amount sensor is greater than a reference value and perform control of interrupting a charging process.
