Title:
METHOD AND APPARATUS FOR CONTROLLING CHARGING AND DISCHARGING CIRCUIT, AND DEVICE, SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/202304
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. A neutral line of an electric motor in a charging and discharging circuit is connected to a charging and discharging switchover bridge arm group. The method comprises: during the process of a charging and discharging circuit charging and discharging a power battery, acquiring, in real time, a first current value in a neutral line; and regulating and controlling the magnitude of the first current value according to the first current value, a first peak current and a second peak current, wherein the first peak current is a known peak current of a charging and discharging switchover bridge arm group, and the second peak current is a known peak current of the neutral line. In the method for controlling a charging and discharging circuit in the present application, according to a first current value in a neutral line, a known peak current of a charging and discharging switchover bridge arm group and a known peak current of the neutral line, the magnitude of the first current value is regulated and controlled, such that the current can be adjusted in a timely manner when an abnormal current value occurs during a charging and discharging process of a power battery, thereby avoiding damage to a circuit.
