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.
La présente invention concerne un procédé de charge de batterie et un dispositif de charge de batterie. Selon un aspect, la présente invention concerne un procédé de charge de batterie comprenant les étapes consistant à mesurer l'impédance pour chaque fréquence en appliquant de manière séquentielle un courant alternatif ayant une fréquence différente par rapport à une batterie ; à partir des impédances mesurées pour chaque fréquence, une étape consistant à définir la fréquence du courant alternatif à laquelle la diffusion chimique commence dans la batterie comme fréquence de résistance à la diffusion ; et une étape consistant à charger la batterie en appliquant à celle-ci un courant de charge par impulsions à une fréquence de charge qui est supérieure à la fréquence de résistance à la diffusion.
