The present invention relates to a technology for fast charging of electric vehicle batteries, and to a fast charging method of electric vehicle batteries, which uses pulse modulation of the voltage, current, and frequency of charging power according to charging stages so as to safely perform charging in a short period of time and prevent the deterioration process that shortens the life of a battery. The fast charging method of electric vehicle batteries comprises a step of detecting the voltage, current and temperature of an electric vehicle battery and calculating the residual capacity, a first constant current charging step (a), a second constant current charging step (b), a constant voltage charging step (c), and a pulse voltage charging step (d).

    본 발명은 전기자동차 배터리 급속 충전 기술에 관한 것으로서, 충전 단계에 따라 충전하는 전력의 전압, 전류, 주파수를 펄스 변조를 이용함으로써 빠른 시간 내에 안전하게 충전을 수행하면서도 배터리의 수명을 단축시키는 열화 과정을 방지할 수 있는 배터리 급속 충전하는 방법에 관한 것이다.
