Document Type and Number:
WIPO Patent Application WO/2023/226562
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and apparatus for controlling a charging and discharging circuit, and a device, a system, and a storage medium. The method comprises: sending charging and discharging enable signals, controlling a switch module and a charging and discharging switching module to act, and forming, in a charging and discharging circuit, a first charging and discharging loop and a second charging and discharging loop which are alternately switched; the first charging and discharging loop comprising a first discharging loop for a first battery pack to discharge an energy storage module and a first charging loop for the energy storage module to charge a second battery pack; and the second charging and discharging loop comprising a second discharging loop for the second battery pack to discharge the energy storage module and a second charging loop for the energy storage module to charge the first battery pack. According to the method of the present application, alternating current flows between the at least two battery packs, the internal self-heating of the battery packs is achieved, the fast heating current frequency in a larger range can be achieved, the low-frequency self-heating of the battery packs can be achieved, the self-heating efficiency is high, and the self-heating effect is good.
