Title:
CONTROL CIRCUIT, METHOD AND SYSTEM FOR BATTERY OSCILLATORY HEATING, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/246324
Kind Code:
A1
Abstract:
The present application belongs to the technical field of new energy. Disclosed are a control circuit, method and system for battery oscillatory heating, and a readable storage medium. In the present application, a switch module is added to a bus capacitor branch, and an on-off state of the switch module is controlled, such that the control circuit for battery oscillatory heating can form an electric motor driving circuit and a heating circuit, which correspond to two working modes, that is, an electric motor driving mode and a heating mode; and by means of controlling an electric motor controller to change the output torque of an electric motor, the heating circuit is formed when the output torque of the electric motor is zero, and a bus capacitor is switched from the heating circuit by means of the switch module.
