Title:
AC CURRENT SUPPLY APPARATUS FOR BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/048474
Kind Code:
A1
Abstract:
According to the present invention, an electrodeposition reduction mode is operated. In this electrodeposition reduction mode, an AC current is supplied to a battery in order to reduce an electrodeposition material in the battery. This electrodeposition mode is operated in a higher battery temperature range than that in the conventional battery heating mode that is embodied for heating the battery. The AC current used in this electrodeposition mode is composed of a high-rate discharge current component supplied in a short discharge period and a low-rate charge current component supplied in a long discharge period. These discharge and charge periods are alternately repeated. In an example, an AC current supply circuit, which supplies an AC current to the battery, has a step-down transformer. When a primary AC voltage is applied to a primary coil of the step-down transformer, a secondary coil of the step-down transformer circulates a secondary AC current in a closed loop circuit including the battery. This close-loop circuit has an energy storing device that stores power energy discharged from the battery. The power energy stored in the energy storing device is supplied again to the battery. Accordingly, the step-down transformer becomes compact. In another example, the AC current supply circuit includes a plurality of inductors which are charged in parallel and are sequentially discharged.
