Abstract

The invention discloses a low-voltage power-off method of a hydrogen energy vehicle. The hydrogen energy vehicle comprises a keyless system PEPS, an electronic steering column lock ESCL, a one-key start switch SSB, an ACC gear relay, a vehicle speed detection assembly, a brake pedal assembly and an IGN gear relay, wherein the electronic steering column lock ESCL, the one-key start switch SSB, theACC gear relay, the vehicle speed detection assembly, the brake pedal assembly and the IGN gear relay are all in communication connection with the keyless system PEPS. The low-voltage power-off methodcomprises an ON-gear normal power-off control step and an ON-gear emergency power-off control step. The low-voltage power-off method of the hydrogen energy vehicle has the advantages of being safe and reliable.

Description

technical field [0001] The invention relates to the field of hydrogen fuel cells, and more specifically, to a low-voltage power-off method for a hydrogen energy vehicle. Background technique [0002] Hydrogen vehicles, as the name suggests, are vehicles that use hydrogen as the energy source, converting the chemical energy generated by the hydrogen reaction into mechanical energy to propel the vehicle. With the promotion and popularization of hydrogen energy vehicles, hydrogen energy vehicles are increasingly in urgent need of low-voltage power-on and power-off control strategies and logic during the development of hydrogen energy vehicles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a low-voltage power-off method for hydrogen energy vehicles in view of the urgent need for low-voltage power-on and power-off control strategies and logic in the development process of hydrogen-energy vehicles in the prior art. ...
