The invention relates to a battery energy processing device and a vehicle. The device comprises an inverter, an energy storage element and a controller, the controller is used for controlling the inverter to charge and discharge the energy storage element and the battery in a first preset state so as to realize self-heating of the battery; and in a second preset state, the energy storage element and the inverter are multiplexed to form a voltage adaptive charging module, and the inverter is controlled to charge the battery. Thus, in the first preset state, the energy storage element is used for achieving battery self-heating, the battery temperature is well maintained, the vehicle driving capacity is guaranteed, self-heating energy loss is small, heat transfer is uniform, and the heating efficiency is high. In the second preset state, the battery energy processing device can reuse the energy storage element and the inverter to form a voltage adaptive charging module, and controls the inverter to charge the battery. The battery energy processing device is shared by battery charging and battery self-heating, so that the battery energy processing device is multifunctional, and the part cost and the volume space are saved.

    本公开涉及一种电池能量处理装置和车辆。装置包括:逆变器、储能元件及控制器;控制器用于:在第一预设状态下,控制逆变器使储能元件与电池进行充电和放电,以实现电池自加热;在第二预设状态下,复用储能元件和逆变器形成电压适配充电模块,且控制逆变器,以对电池充电。这样,在第一预设状态下,利用储能元件实现电池自加热,较好维持电池温度,保障车辆驱动能力,自加热能量损耗小、传热均匀、加热效率高。在第二预设状态下,电池能量处理装置还可复用储能元件和逆变器形成电压适配充电模块,并控制逆变器,以对电池充电。即电池充电和电池自加热共用一套电池能量处理装置,实现电池能量处理装置的多功能复用,节省零部件成本和体积空间。
