High-pressure hydrogen storage system of hydrogen energy light truck

Abstract

The invention discloses a high-pressure hydrogen storage system of a hydrogen energy light truck. The hydrogen storage system specifically comprises a first hydrogen storage module, a second hydrogen storage module, a hydrogen inlet module, a hydrogen outlet module and an electric pile; the first hydrogen storage module and the second hydrogen storage module are connected in parallel; the hydrogen inlet module communicates with the first hydrogen storage module and the second hydrogen storage module; the hydrogen outlet module communicates with the first hydrogen storage module and the second hydrogen storage module; a first temperature sensor and a second temperature sensor are arranged on the first hydrogen storage module and the second hydrogen storage module correspondingly; a first temperature driving safety pressure relief module is arranged on a flow path between the first hydrogen storage module and a hydrogen outlet; a second temperature driving safety pressure relief module is connected to a flow path between the second hydrogen storage module and the hydrogen outlet in series; and the electric pile is connected with the hydrogen outlet module. According to the arrangement mode of the system, integrated design is adopted, all parts are subjected to modularization treatment, the cargo carrying space of the whole truck is improved, the hydrogen storage capacity of the system can be greatly improved, and the long-endurance mileage requirement is met.

Description

technical field [0001] The invention belongs to the technical field of high-pressure hydrogen storage, and in particular relates to a high-pressure hydrogen storage system for a hydrogen-powered light truck. Background technique [0002] With the increasingly tight energy supply, the development of new energy trucks is imminent. It is undoubtedly the best choice to use hydrogen energy as a fuel for trucks.
