摘要： In some implementations, a method may include obtaining target fault data indicating a preselected fault for a vehicle having a hydrogen source. In addition, the method may include obtaining vehicle fault data indicating a fault of the vehicle. The method may include identifying a match between the fault and the preselected fault. Moreover, the method may include purging, in response to the identifying the match, hydrogen from the hydrogen source so as to reduce consequences of a battery thermal event by reducing the likelihood of a hydrogen-fueled fire.

摘要： The present disclosure relates to systems and methods of detecting a hydrogen leak in a system comprising a hydrogen storage system storing hydrogen, a temperature sensor, a pressure sensor, a hydrogen storage system controller, and a notification system. The hydrogen storage system controller is configured to measure thermodynamic properties of the hydrogen in the hydrogen storage system, and the thermodynamic properties of the hydrogen are used to determine if there is a hydrogen leak in the fuel cell system. The notification system alerts a user of any detected hydrogen leak.
