Disclosed are a battery charging method and a battery charging apparatus. According to one aspect of the present invention, the battery charging method comprises the steps of: sequentially applying an alternating current of different frequencies to a battery and measuring impedance for each frequency; setting a frequency of the alternating current at which chemical diffusion starts in the battery as a diffusion resistance frequency from the measured impedance for each frequency; and charging the battery by applying a pulse charging current to the battery at a charging frequency higher than the diffusion resistance frequency. The battery charging method can charge the battery at a high speed.

    배터리 충전 방법 및 배터리 충전 장치가 개시된다. 본 발명의 일 측면에 따르면, 배터리에 대해 서로 다른 주파수의 교류 전류를 순차적으로 인가하여 주파수별 임피던스를 측정하는 단계와; 상기 측정된 주파수별 임피던스로부터 상기 배터리에서 화학적 확산이 시작되는 상기 교류 전류의 주파수를 확산 저항 주파수로 설정하는 단계와; 상기 확산 저항 주파수보다 높은 주파수의 충전 주파수로 펄스 충전 전류를 상기 배터리에 인가하여 상기 배터리를 충전하는 단계를 포함하는, 배터리 충전 방법이 제공된다.
