The invention provides a method and a device for temperature control of an electric automobile vacuum boosting system. The device comprises: a first heating module used for heating a brake master cylinder; a second heating module used for heating air entering an air filter; a first temperature detection module used for obtaining cylinder body temperature information of the brake master cylinder and sending the cylinder body temperature information to a whole vehicle control system; a second temperature detection module used for acquiring air temperature information near the vacuum booster andsending the air temperature information to the vehicle control system; a first receiving module used for acquiring information sent by the vehicle control system; and a first processing module used for controlling circuit on-off and heating power of the second heating module and the first heating module. The method and the device can effectively prevent the situation that the vacuum boosting system of the electric automobile cannot normally operate in a low-temperature environment.
