Medium pressure hydrogen storage pipeline of the integrated replacement service port has numerous features such as large flow, high durability, low permeability, which can satisfy the safety requirements of high amplitude and low permeability to medium pressure pipeline for vehicle HSS and can improve the convenience of vehicle assembly. The inner diameter of the pipeline can be increased by 30%, and the weight can be reduced by about 80%
Salt tolerance 500 hours
Hydrogen tank mounting frame used environmentally friendly and high rust resistance surface treatment technology, salt spray resistance test can reach 500 hours.
Valve weight: 650g
The highly integrated pressure regulator weighs only 650g and is equipped with 5 high pressure ports along the axis, which can improve the valve integration degree and space utilization.
More than 30%
After hydrogen storage system pipeline and valve structure optimization, more than 30% components and parts have been reduced.
High security
The self-developed HMS (Hydrogen Management System) integrates the functions of hydrogen storage system valve control and safety strategy, which can actively monitor the safety of HSS.
Full life cycle
Based on a comprehensive analysis of vehicle customer requirements, the hydrogen storage system (HSS) has been designed for its full life cycle and adopted modular assembly.
Commercial Vehicle On-Board Hydrogen Storage System
This system is equipped with its self-developed on-tank valve (OTV) and pressure reducing regulator valve , and has the advantages of modularity, integration, intelligence, which can reduce more than 30% of the potential leakage.
