WIPO Patent Application WO/2022/231062
Kind Code:
A1
Abstract:
Disclosed is a battery charging method and a battery charging device. Provided according to one aspect of the present invention is a battery charging method comprising the steps of measuring impedance for each frequency by sequentially applying an alternating current having a different frequency with respect to a battery; from the measured impedances for each frequency, a step for setting the frequency of the alternating current at which chemical diffusion initiates in the battery as a diffusion resistance frequency; and a step for charging the battery by applying thereto a pulse charging current at a charging frequency that is higher than the diffusion resistance frequency.
