The invention relates to an electric vehicle braking energy recovery device and method and an electric vehicle. The electric vehicle braking energy recovery device comprises a multi-gear switch (1), and a vehicle control unit; the multi-gear switch (1) is provided with at least two gears and is configured to select different load working conditions of a vehicle by receiving external operation, andthe at least two gears are in one-to-one correspondence with different load working condition levels, wherein different load working conditions correspond to different load intervals; and the vehiclecontrol unit (3) is electrically connected with the multi-gear switch (1) and is configured to conduct matching according to the corresponding relation between the load working condition selected bythe multi-gear switch (1) and preset working condition-brake feedback parameters so as to obtain the brake feedback parameters of the vehicle under the current load working condition and enable the vehicle to perform brake energy recovery according to the determined brake feedback parameters.

    本公开涉及一种电动汽车制动能量回收装置及回收方法、电动汽车,其中,电动汽车制动能量回收装置包括多档开关(1),具有至少两个档位,被配置为通过接收外部操作选择车辆不同的载荷工况,至少两个档位与不同的载荷工况等级一一对应,不同的载荷工况对应的载荷区间不同;以及整车控制器(3),与多档开关(1)电连接,被配置为根据多档开关(1)选择的载荷工况与预设的工况‑制动回馈参数的对应关系进行匹配,以获得车辆在当前载荷工况下的制动回馈参数,并使车辆按照确定出的制动回馈参数进行制动能量回收。
