The invention provides an annular power supply system for an electric vehicle. The system comprises a plurality of high-voltage units and a range extender, wherein the high-voltage units are connected into an annular framework by high-voltage interconnection lines; each high-voltage unit comprises a comprehensive controller and a high-voltage power supply module consisting of a power battery; the range extender is connected with the comprehensive controller of each high-voltage unit and is used for providing high voltage for the comprehensive controller; the comprehensive controller is used for performing power distribution control, state monitoring and overcurrent protection on vehicle high-voltage equipment; the high-voltage power supply modules of the plurality of high-voltage units are connected in parallel through the high-voltage distribution box, and when part of the high-voltage power supply modules break down, the normal high-voltage power supply modules supply power to the comprehensive controllers of other high-voltage units and supply high-voltage power to the vehicle high-voltage equipment. Redundant power supply for the vehicle high-voltage equipment can be realized, the risk of high-voltage power failure of the vehicle is reduced, and the reliability of high-voltage power supply of the whole vehicle is improved.

    本发明提供一种电动车辆环形供电系统。所述系统包括由高压互联线连成环形架构的多个高压单元和增程器,所述高压单元包括综合控制器和由动力电池组成的高压电源模块;所述增程器与每个高压单元的综合控制器相连,用于为综合控制器提供高压;所述综合控制器用于对车辆高压设备进行配电控制、状态监测及过流保护;多个高压单元的高压电源模块通过高压配电箱并联在一起,当部分高压电源模块发生故障时,正常高压电源模块为其它高压单元的综合控制器供电,并为车辆高压设备提供高压电源。本发明能够实现对车辆高压设备的冗余供电,降低了车辆高压掉电的风险,提高了整车高压供电的可靠性。
