US 2026/0074527 A1 · CHARGE AND DISCHARGE CONTROL METHOD AND APPARATUS, AND DEVICE, STORAGE MEDIUM AND PROGRAM PRODUCT

Abstract

A charge and discharge control method comprises: when a battery heating condition is satisfied, turning on a connecting circuit between a neutral point of a first electric motor and a neutral point of a second electric motor, wherein a first electric motor controller connected to the first electric motor and a second electric motor controller connected to the second electric motor are both connected between a positive electrode and a negative electrode of a battery; and controlling the turning-on/turning-off of bridge arms in the first electric motor controller and the second electric motor controller, and forming, in a circuit in which the battery is located, a charging loop and a discharging loop which are alternately switched.
