This application provides an electric vehicle battery control circuit, system, and control method. The electric vehicle battery control circuit includes an electric vehicle battery, an energy storage module, a charging module, and a regulation switch component; where the charging module includes a switch module; the electric vehicle battery is connected in parallel with the switch module; the regulation switch component includes multiple switches, where the multiple switches are disposed between the electric vehicle battery and the charging module and between the energy storage module and the charging module; and the energy storage module, the regulation switch component, and the switch module are configured to, in response to control signals, regulate charging/discharging between the electric vehicle battery and the energy storage module, or regulate charging/discharging between the electric vehicle battery and the charging module as well as the energy storage module. This meets different heating needs of the electric vehicle battery.
