Based on Huahai Technology's RapidECU all-domain electronic control development platform, this solution addresses industry pain points of on-board hydrogen storage systems — large pressure fluctuation, low hydrogen-refueling temperature control precision, incomplete tank-group status monitoring, single-dimensional pressure relief logic, high pipeline leakage risk, poor high/low temperature adaptability and difficult multi-tank coordinated management — delivering a professional overall Hydrogen Storage Control Unit (HSCU) solution. As the upstream core management unit of on-board hydrogen energy, the solution focuses on full-status management of high-pressure hydrogen storage tank groups, inlet/outlet pipelines and valve assemblies, realizing core functions such as hydrogen refueling closed-loop control, tank-group temperature/pressure monitoring, multi-level pressure relief protection, pipeline fault diagnostics, residual hydrogen management and hydrogen system safety interlock, providing upfront assurance for stable fuel cell supply and safe vehicle hydrogen operation. Backed by a full proprietary toolchain — ECUCoder automatic code generation, MeCa hydrogen-specific calibration, SimCar hydrogen-storage-system-dedicated HIL simulation and SimCore hydrogen system virtual simulation — it is fully compatible with MATLAB/Simulink model-based development, supports the AUTOSAR architecture and the ISO 26262 functional safety system, and adapts to 35MPa/70MPa high-pressure hydrogen storage systems and single-/multi-tank storage architectures. It covers the full lifecycle of prototype algorithm validation, bench commissioning, vehicle hydrogen matching calibration and mass production, effectively improving hydrogen-refueling efficiency, supply stability, condition adaptability and vehicle hydrogen safety redundancy.
