Abstract

Provided is an electric vehicle control method that selectively executes either a first power limit mode or a second power limit mode as a battery thermal protection mode in which a vehicle driving force is limited based on an upper limit battery power. In the first power limit mode, the upper limit battery power is calculated using a basic upper limit battery power function. In particular, the basic upper limit battery power function is determined to decrease in accordance with an increase in the battery temperature in a temperature region equal to or higher than a basic battery protection temperature. In the second power limit mode, the upper limit battery power is calculated using a corrected upper limit battery power function. In particular, the corrected upper limit battery power function is determined to decrease at a change rate lower than that of the basic upper limit battery power function in accordance with the increase in the battery temperature in a temperature region equal to or higher than a corrected battery protection temperature lower than the basic battery protection temperature.
