Abstract: 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.

Abstract: The voltage at the high voltage terminal of a first particle accelerator is stabilized particularly during pulsed operation by producing a compensating current at its accelerator terminal such as to maintain the voltage of the terminal constant. The compensating current is produced by a second particle accelerator coupled between the accelerator terminal and a high voltage terminal connected with a high voltage DC power supply. The charged particle flow through the second particle accelerator is such that the charge on the accelerator terminal of the first accelerator remains substantially constant even though the voltage at the high voltage terminal drops during simultaneous pulsed operation of both particle accelerators.
