Abstract

A battery heating device of an electric vehicle, a battery heat adjustment method, a storage medium, and an electronic device are provided. The device includes a battery heating circuit, an engine cooling circuit and a three-way valve. The three-way valve connects the battery heating circuit and the engine cooling circuit to mix a first liquid in the engine cooling circuit and a second liquid in the battery heating circuit, and transmits a mixed liquid to the battery heating circuit to heat a battery in the battery heating circuit. By means of the disclosure, the problems of large overall weight and packaging space of a system caused by the use of a heat exchanger and high manufacturing cost in a conventional art are solved, the overall weight and packaging space of the system are reduced, additional components are reduced, and the cost is reduced.
