The invention relates to an energy recovery control method and device of an electric automobile, the automobile, equipment and a medium. The method comprises the steps that the available electricity quantity of a power battery of the electric vehicle is detected in response to the braking state of the electric vehicle; if the available electric quantity is larger than the preset electric quantity, the braking requirement of the electric vehicle is detected; a target high-pressure accessory needing to be regulated and controlled is determined according to the braking requirement; driving the target high-voltage accessory to work according to the preset regulation and control parameters corresponding to the target high-voltage accessory; the consumed power of the target high-voltage accessory is monitored, and the allowable recovery power of the electric vehicle is controlled to change along with the consumed power; the target high voltage accessory is energized using energy recovered based on the allowable recovery power. According to the method, the allowable recovery power of the electric vehicle is improved through the high-voltage accessory, the recovered energy is used as the function of the target high-voltage accessory, the difference between the allowable recovery power under the condition of different available electric quantities is reduced, and then the difference between the deceleration efficiency and the braking distance is achieved.
本申请涉及一种电动汽车的能量回收控制方法、装置、汽车、设备和介质。所述方法包括:响应电动汽车处于制动状态,检测电动汽车的动力电池的可用电量;若可用电量大于预设电量,检测电动汽车的制动需求;根据制动需求确定需要调控的目标高压附件;根据目标高压附件对应的预设调控参数驱动目标高压附件进行工作;监测目标高压附件的消耗功率,并控制电动汽车的允许回收功率随消耗功率进行变化;使用基于允许回收功率回收得到的能量为目标高压附件供能。本方法通过高压附件提高电动汽车的允许回收功率,并使用回收得到的能量为目标高压附件功能,缩小在不同的可用电量情况下的允许回收功率之间的差异,进而减速效率和制动距离之间的差异性。
