The invention discloses an energy recovery monitoring method and device for an electric vehicle, a vehicle and a storage medium, and the method comprises the steps that the power battery charging voltage, the power battery charging current, the driving motor output torque, the driving motor output current, a vehicle speed signal and a whole vehicle weight signal of the electric vehicle are collected; the actual braking energy conversion efficiency, the actual braking energy recovery rate and the actual braking energy recoverable proportion of the electric vehicle are calculated; and generating energy recovery monitoring data. Therefore, the problems that limited data in the test process can only be recorded, the comprehensiveness and the effectiveness of the experiment in the experiment process cannot be ensured, the real-time performance of problem discovery is reduced, response cannot be made quickly, the test requirement of the electric vehicle cannot be met, and the test efficiency of the electric vehicle cannot be improved due to the fact that the test is carried out in a specific rotating hub laboratory in the prior art are solved. And the real-time performance and the practicability of the test are low.
本申请公开了一种电动汽车的能量回收监控方法、装置、车辆及存储介质,其中,方法包括:采集电动汽车的动力电池充电电压、动力电池充电电流、驱动电机输出扭矩、驱动电机输出电流、车辆速度信号和整车重量信号;计算电动汽车的实际制动能量转化效率、实际制动能量回收率和实际制动能量可回收占比;生成能量回收监控数据。由此,解决了相关技术中由于在特定的转毂实验室中进行,导致只能记录测试过程中的有限数据,无法确保在实验过程中实验的全面性及有效性,降低问题发现的实时性,使得无法快速做出响应,无法满足电动汽车的测试需求,测试的实时性和实用性较低等技术问题。
