The invention relates to a vehicle kinetic energy recovery braking method and system, and the method comprises the steps: collecting an SOC value of a power battery when a vehicle decelerates and brakes, and comparing the SOC value with an SOC protection limit value; if the SOC value is larger than or equal to the SOC protection limit value, the kinetic energy recovery generator is controlled to be communicated with the electric energy processing device; otherwise, controlling the kinetic energy recovery generator to be communicated with the power battery. According to the invention, the battery SOC is compared with the battery SOC protection limit value, so that when the battery SOC is greater than or equal to the battery SOC protection limit value, the electric energy processing device operates and recovers the electric energy generated by the kinetic energy recovery generator, and when the battery reaches the SOC protection limit value, the kinetic energy recovery function can still be realized.
本申请涉及一种车辆动能回收制动方法及其系统,其包括:当车辆减速制动时,采集动力电池的SOC值,并与SOC保护限值进行比较;若SOC值大于等于SOC保护限值,则控制动能回收发电机连通电能处理装置;否则,控制动能回收发电机连通动力电池。本发明中,将电池SOC与电池SOC保护限值进行比较,以确保电池SOC大于等于电池SOC保护限值时,电能处理装置运行,回收动能回收发电机产生的电能,使电池达到SOC保护限值时,仍能实现动能回收功能。
