The present application provides a battery thermal management system, a control method and device of a battery heating system, a device, and a medium. The method includes: acquiring a temperature rise rate parameter of the battery; determining proportions of a square wave signal and a sine wave signal in a first control signal of the switch components according to the temperature rise rate parameter; generating the first control signal of the switch components according to the proportions of the square wave signal and the sine wave signal; outputting the first control signal to the switch components to control switching on or off of the switch components via the first control signal, so as to generate an alternating current in a loop connecting the battery and the motor and heat the battery using the alternating current.
