Abstract

The invention discloses a calculation method and device for total residual energy of a hydrogen fuel cell vehicle. The method comprises the steps: firstly acquiring the electric quantity data of the hydrogen fuel cell vehicle, then acquiring the working condition of the hydrogen fuel cell vehicle according to the electric quantity data, finally acquiring the corresponding hydrogen consumption data according to the working condition of the hydrogen fuel cell vehicle, performing calculation to obtain first energy according to the hydrogen consumption data and the electric quantity data, and performing calculation to obtain total residual energy of the hydrogen fuel cell vehicle according to the first energy, wherein the first energy is electric energy converted by unit hydrogen. By adopting the embodiment of the invention, the accuracy of calculating the total residual energy of the hydrogen fuel cell vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell vehicles, in particular to a method and device for calculating the total remaining energy of a hydrogen fuel cell vehicle. Background technique [0002] At present, the energy of most hydrogen fuel cell vehicles in China is displayed as two parts: the remaining hydrogen and the remaining battery, and the remaining hydrogen and battery are usually displayed as a percentage value, and there is no display value for the total remaining energy of the two. [0003] In daily life, although some hydrogen fuel cell vehicles can calculate the total remaining energy after converting the remaining amount of hydrogen into electrical energy, the hydrogen consumption of hydrogen fuel cell vehicles under different working conditions is not considered in the prior art, so for hydrogen The calculation of the remaining amount is not accurate enough, which eventually leads to the inaccuracy of calculating ...
