The invention relates to an insulation fault diagnosis system and method of a fuel cell system and the fuel cell system. Comprising a troubleshooting assembly with a plurality of troubleshooting nodes, and the troubleshooting assembly is used for adjusting the connection state between the multiple troubleshooting nodes and multiple to-be-troubleshot points according to the current troubleshooting requirement; the control assembly is respectively connected with the plurality of troubleshooting nodes and is used for sending a current troubleshooting demand to the troubleshooting assembly and determining parts in an insulation failure state in the fuel cell system according to a troubleshooting result of each to-be-troubleshot point after the troubleshooting assembly adjusts a connection state between the plurality of troubleshooting nodes and the plurality of to-be-troubleshot points; and the display assembly is connected with the control assembly and is used for displaying the parts in the insulation failure state. Therefore, by means of the insulation fault diagnosis system, the problems that in the prior art, when insulation fault diagnosis is carried out, specific fault parts cannot be automatically positioned, and insulation faults caused by high-voltage loop failure or cooling loop failure cannot be distinguished can be solved.
本申请涉及一种燃料电池系统的绝缘故障诊断系统及方法、燃料电池系统。包括:具有多个排查节点的故障排查组件,用于根据当前排查需求调节多个排查节点与多个待排查点之间的连接状态;分别与多个排查节点相连的控制组件,用于发送当前排查需求至故障排查组件,并在故障排查组件调节多个排查节点与多个待排查点之间的连接状态后,根据每个待排查点的排查结果确定燃料电池系统中处于绝缘失效状态的零部件;与控制组件相连的显示组件,用于显示处于绝缘失效状态的零部件。由此,通过该绝缘故障诊断系统能够解决现有技术进行绝缘故障诊断时无法自动定位到具体故障零部件,以及无法区分是高压回路失效还是冷却回路失效带来的绝缘故障的问题。
