The invention relates to an electric vehicle energy management method based on curve prediction, terminal equipment and a storage medium. The method comprises the following steps: S1, counting the average acceleration av of vehicle deceleration; s2, acquiring curve information of a road ahead through an electronic horizon system; s3, predicting the energy recovery amount during turning according to the curve information and the highest turning speed of the vehicle; and S4, adjusting the logic threshold value of the current driving according to the predicted turning energy recovery amount. According to the method provided by the invention, the super capacitor can output more energy in advance according to the energy which is possibly recovered during the forward turning, so that an energy recovery space is vacated, the energy is recovered during the turning, the power output of the battery can be reduced, the energy recovery is ensured, and the positive effects of reducing loss and saving energy and controlling are achieved.

    本发明涉及一种基于弯道预测的电动车能量管理方法、终端设备及存储介质。该方法包括以下步骤:S1.统计车辆减速的平均加速度av;S2.通过电子地平线系统获取前方道路的弯道信息;S3.根据弯道信息和车辆的最高过弯速度来预测过弯时的能量回收量;S4.根据预测的过弯能量回收量调整当前行驶的逻辑门限值。本发明的方法能根据前方过弯时可能回收的能量,提前让超级电容多输出能量,以腾出能量回收空间,在过弯时再回收能量,能减少电池的功率输出,保证能量回收,起到减少损耗,节能控制的积极作用。
