The present invention relates to a secondary battery charging system. More specifically, according to the present invention, considering a voltage drop, a charging start voltage of a secondary battery is provided close to a chargeable voltage of the secondary battery. Additionally, the charging voltage of the secondary battery is detected in real time and the charging voltage is controlled. Therefore, a charging time required to charge the secondary battery from 20 % to 80 % can be reduced from 40 minutes to 10 minutes. The secondary battery charging system of the present invention comprises: a power supplier; and a charger.
본 발명은 이차전지 충전시스템에 관한 것으로, 더욱 상세하게는 이차전지의 충전개시전압을 전압강하를 고려하여 이차전지 충전가능전압과 근접하게 제공하고, 실시간으로 이차전지의 충전전압을 검출하여 충전전압을 제어함으로써 이차전지를 20%에서 80%로 충전시키는데 드는 충전시간을 40분에서 10분으로 감소시킬 수 있는 이차전지 충전시스템에 관한 것이다.
