A method for torque control of an electric vehicle on a slippery road surface and a terminal device are provided. The method includes: presetting a torque-lower-limit-value; setting, when an anti-lock braking system of the electric vehicle is activated, the torque-lower-limit-value as a second numerical value to reduce an absolute value of a reverse torque exerted on the vehicle wheel due to the energy recovery, and the vehicle wheel enters an anti-lock state; maintaining the anti-lock state of the vehicle wheel for a preset first time period; comparing the currently requested torque value with a preset third numerical value after the first time period is passed; and resetting the torque-lower-limit-value to the first numerical value to enable the vehicle wheel to exit the anti-lock state, if the currently requested torque value is greater than the third numerical state.
