Electric vehicle energy management method based on bend prediction, terminal device, and storage medium

The present disclosure relates to an electric vehicle energy management method based on bend prediction, a terminal device, and a storage medium. The method includes the following steps: S. counting an average acceleration aof vehicle decelerations; S. acquiring bend information of a road ahead by an e-horizon system; S. predicting energy recovery amount during cornering based on the bend information and a maximum cornering speed of a vehicle; and S. adjusting a logic threshold value for current driving based on the predicted energy recovery amount. With the method of the present disclosure, a supercapacitor can output more energy in advance based on energy likely to be recovered during cornering ahead, so as to free up energy recovery space and to recover energy during cornering, which can reduce power output of a battery, ensure energy recovery, and play a positive role in loss reduction and energy-saving control.
