A battery charging system comprises: a first battery pack including a first battery charged through non-contact connection; and a second battery pack including a second battery charged through non-contact connection, a first capacitor serially connected between a cathode and an anode of the second battery, and a first BMS configured to measure the voltage of the second battery and voltages at both ends of a second capacitor, wherein the first BMS charges the second battery with the voltage of the first battery when the voltage of the first battery is higher than the voltage of the second battery, and charges the first battery with the voltage of the second battery when the voltage of the first battery is lower than the voltage of the second battery.

    L'invention concerne un système de charge de batterie comportant : un premier bloc-batterie comprenant une première batterie chargée par liaison sans contact ; et un second bloc-batterie comprenant une seconde batterie chargée par liaison sans contact, un premier condensateur relié en série entre une cathode et une anode de la seconde batterie, et un premier calculateur BMS conçu pour mesurer la tension de la seconde batterie et les tensions aux deux extrémités d'un second condensateur, le premier calculateur BMS chargeant la seconde batterie avec la tension de la première batterie lorsque la tension de la première batterie est supérieure à la tension de la seconde batterie, et chargeant la première batterie avec la tension de la seconde batterie lorsque la tension de la première batterie est inférieure à la tension de la seconde batterie.

    배터리 충전 시스템으로서, 제1 배터리팩은 비접촉 연결로 충전되는 제1배터리를 포함하고, 제2 배터리팩은, 비접촉 연결을 통해 충전되는 제2 배터리, 제2 배터리의 양극과 음극 사이에 직렬 연결된 제1 커패시터, 및 제2 배터리의 전압과 제2 커패시터의 양단 전압을 측정하도록 구성된 제1 BMS를 포함하고, 제1 BMS는, 제1 배터리 전압이 상기 제2 배터리 전압보다 큰 경우 제1 배터리의 전압으로 제2 배터리를 충전하고, 제1 배터리 전압이 제2 배터리 전압보다 작은 경우 제2 배터리의 전압으로 제1 배터리를 충전한다.
