The invention discloses a braking energy recovery method and a braking energy recovery system, and relates to the technical field of electric automobiles, the disclosed energy recovery method is applied to an electric vehicle provided with an energy recovery pedal, and comprises the steps that when a first braking request triggered by a user based on the energy recovery pedal is received, a motor braking deceleration threshold value is obtained; the motor braking deceleration threshold value is scaled, and the current motor braking deceleration is obtained; braking according to the current motor braking deceleration; and kinetic energy generated in the braking process is converted into electric quantity to charge a power battery according to the current motor braking deceleration. The current motor braking deceleration used for braking energy recovery is obtained by scaling the motor braking deceleration threshold value, so that the current motor braking deceleration can be limited within the motor braking deceleration threshold value, the braking energy recovery process is smoother, the pause feeling brought to a user in a vehicle is avoided, and the user experience is improved. And the riding experience is effectively improved.

    本申请公开了一种制动能量回收方法及制动能量回收系统,涉及电动汽车技术领域,公开的能量回收方法应用于设有能量回收踏板的电动车辆,包括:在接收到用户基于能量回收踏板触发的第一制动请求时,获取电机制动减速度阈值;对电机制动减速度阈值进行缩放,得到当前电机制动减速度;根据当前电机制动减速度进行制动;根据当前电机制动减速度将制动过程中产生的动能转换为电量对动力电池进行充电。本申请用于制动能量回收的当前电机制动减速度通过对电机制动减速度阈值进行缩放所得,因此,能够将当前电机制动减速度限制在电机制动减速度阈值内,使得制动能量回收过程更为平顺,避免给车内用户带来顿挫感,有效提高了乘车体验。
