The invention provides a multi-voltage platform hydrogen fuel cell automobile energy system, which mainly optimizes the framework of an automobile energy system and adds an auxiliary energy system. The auxiliary energy system comprises a super capacitor, a super capacitor bidirectional DC/DC, a nickel-metal hydride battery and a nickel-metal hydride battery bidirectional DC/DC, and is used for making up the instantaneous large power required by the whole vehicle, absorbing the redundant power of a fuel cell engine and the feedback power of a motor and supplying power to electric equipment of alow-voltage platform at the same time. The system has the advantages that the auxiliary energy system is added and is designed into two voltage platforms, namely the 540V platform and the 340V platform, the efficiency of the electric drive system is improved, and meanwhile the problem that other high-voltage components such as PTC, air conditioners and steering pumps do not have the 540V platformis solved. 本发明提供一种多电压平台氢燃
