The invention relates to a two-way power supply system based on multiple sources of a wheeled armored vehicle. The two-way power supply system is used for improving high safety, reliability and efficiency of a double-medium-voltage power grid of the wheeled armored vehicle. The system comprises a bidirectional power conversion system, a load and an external power supply, one end of the bidirectional power conversion system is used for connecting a power battery, the other end of the bidirectional power conversion system is connected with the load and the external power supply, and the load and the external power supply cannot be connected to the bidirectional power conversion system at the same time. According to the invention, the system has high energy feedback capability for a driving power grid and a load, can rapidly switch the input sources inside and outside the vehicle through different modes, has two forward and reverse working modes, adopts different protection strategies in the two modes, and achieves the safety protection of a double-medium-voltage power grid. A power battery of a chassis driving power grid can be charged through a power supply outside the vehicle, and the power battery supplies power to a loading load through a bidirectional power supply conversion system.

    本发明涉及一种基于轮式装甲车辆多源的双向电源系统,用于提高轮式装甲车辆双中压电网的高安全可靠性和高效性。本发明包括双向电源变换系统、载荷以及车外电源,双向电源变换系统的一端用于连接动力电池,双向电源变换系统的另一端连接载荷以及车外电源,载荷和车外电源不能同时接入双向电源变换系统。本发明对驱动电网、载荷具有较高的能量回馈能力,通过不同的方式快速地切换车内/车外输入源,具备正反向两种工作模式,两种模式下采用不同的保护策略,实现对双中压电网的安全保护,此外,可通过车外电源向底盘驱动电网的动力电池充电,以及动力电池通过双向电源变换系统向上装载荷供电。
