The invention relates to the technical field of energy recovery, and provides a tandem type electric automobile braking energy recovery method which comprises the following steps: step 1, detecting whether a current working condition meets an energy recovery condition or not; and 2, if the detection result is yes, whether a brake pedal is stepped down or not is detected, if the detection result is yes, braking energy recovery in a braking mode is carried out, and if the detection result is no, sliding energy recovery in a sliding mode is carried out. And reverse dragging braking force and mechanical braking force can be flexibly distributed, so that the purpose of braking is achieved, and meanwhile, mechanical energy can be converted into electric energy more efficiently.

    本发明涉及能量回收技术领域,提供了一种串联式电动汽车制动能量回收方法,包括如下步骤:步骤1:检测当前工况是否满足能量回收条件;步骤2:若检测结果为是,则检测制动踏板是否踩下,若检测结果为是,则进行制动模式下的制动能量回收,若检测结果为否,则进行滑行模式下的滑行能量回收。可以灵活的对反拖制动力和机械制动力进行分配,从而在达到制动目的同时更高效的对机械能进行电能的转化。
