The invention discloses a fuel cell double-high-voltage power supply based on high-power requirements. The power supply comprises a fuel cell electrically connected with a boost DC-DC converter, and further comprises a power control unit comprising a bidirectional DC-DC converter and a second high-voltage distribution box, a first high-voltage port of the bidirectional DC-DC converter is electrically connected with the boost DC-DC converter, a second high-voltage port of the bidirectional DC-DC converter is electrically connected with an energy storage element, and the boost DC-DC converter isprovided with a first high-voltage port and a second high-voltage port of the second high-voltage distribution box. The invention further discloses a fuel cell double-high-voltage power supply systembased on the high-power requirements. The fuel cell double-high-voltage power supply system comprises the power supply, a first high-voltage device, a second high-voltage device and a low-voltage storage battery. The first high voltage and the second high voltage can be outputted at the same time, the energy storage element can output the first high voltage and the second high voltage when the starting and high-power requirements are large, the situation that the boost DC-DC converter cannot work normally when the output voltage of the fuel cell is too high is avoided, and the high-power requirements are met.

    本发明公开了一种基于大功率需求的燃料电池双高压供电电源,包括燃料电池,燃料电池与升压DC‑DC转换器电性连接,还包括功率控制单元,功率控制单元包括双向DC‑DC转换器和第二高压配电盒,双向DC‑DC转换器的第一高压端口与升压DC‑DC转换器电性连接,第二高压端口与储能元件电性连接,升压DC‑DC转换器设有第一高压端口,第二高压配电盒第二高压端口。本发明还公开了一种基于大功率需求的燃料电池双高压供电系统,包括供电电源、第一高压装置、第二高压装置和低压蓄电池。本发明可同时输出第一高压和第二高压,储能元件可在起动和大功率需求大时输出第一高压和第二高压,避免了当燃料电池输出电压过高时,升压DC‑DC转换器无法正常工作,满足了大功率需求。
