According to the vehicle, the energy conversion device and the discharging method of the energy conversion device, the first inductor, the second inductor and the first bidirectional H bridge are arranged to form different charging and discharging loops with the to-be-charged vehicle, and when it is detected that the voltage of the battery module is not higher than the voltage of the to-be-charged vehicle, charging and discharging are conducted. The first inductor is adopted to boost the voltage of the voltage module and then charge the to-be-charged vehicle, and when the voltage of the battery module is detected to be higher than the voltage of the to-be-charged vehicle, the second inductor charges the to-be-charged vehicle after the battery module charges the second inductor, so that the to-be-charged vehicle is charged by the second inductor regardless of the voltage of the battery module. The vehicle charging system can charge a to-be-charged vehicle, is high in compatibility and adaptability, does not need to additionally add an external step-up or step-down circuit, reduces the cost of an additional circuit, achieves the charging and discharging of vehicles on different voltage platforms, and can achieve the high-power charging without adding a high-voltage inversion conversion device or a control box on a cable.

    本发明提供一种车辆、能量转换装置及其放电方法,通过设置第一电感、第二电感以及第一双向H桥,进而与待充电车辆组成不同的充放电回路,检测到电池模块的电压不高于待充电车辆电压时,采用第一电感对电压模块的电压进行升压后再给待充电车辆电压充电,检测到电池模块的电压高于待充电车辆电压时,使电池模块为第二电感充电后由第二电感给待充电车辆充电,实现了无论电池模块的电压高低,都可以给待充电车辆充电,并且兼容性适应性较强,不需要额外增加外部升压或者降压电路,减少了外加电路的成本,实现不同电压平台车辆之间的充放电,同时无需外加高压逆变转换装置或线缆上控制盒就能实现大功率的充电。
