Abstract

Provided in the embodiments of the present application are a charging and discharging circuit and method, and a computing device and a storage medium. Two energy storage elements in the charging and discharging circuit are connected by means of a first adjustment switch module, after a switch is turned on, heating control is performed, and self-heating of a battery is realized by means of an alternating current generated by a charging and discharging loop between a dual-driving electric motor and the battery. The present application can flexibly adjust a charging and discharging loop between a traction battery and an energy storage element without changing the original structure of an electric motor, such that the cost is reduced, and the charging and discharging of a dual-driving electric motor can be flexibly adjusted so as to implement a battery self-heating scheme, thereby increasing a heating rate.
