We’re delighted to have achieved another major milestone in our vehicle test programme as we progress to dyno metric testing of our hydrogen fuel cell HGV.
Test vehicle X1.5 is the first of several engineering prototypes. Powered by the same cutting-edge hydrogen fuel-cell technology that will be featured in the HVS production vehicles, the X1.5 serves as a crucial platform for functionality and systems development and is an important precursor to subsequent track testing prototypes.
Vehicle X1.5 has now commenced dyno rig testing. This part of the test programme is key to the development process as it allows the engineers to precisely tune the power delivery to provide a smooth and natural driving experience. The vehicle will be driven under very specific conditions to collect reliable data particularly via the rear e-axle and fuel cell systems.
During this part of the test programme, the engineering team will also engage in thermal mapping of the system’s output and will be closely monitoring the cooling of the fuel cells and battery pack to optimise the efficiency of the complete thermal system.
“My team and I are pleased to have assembled our first engineering prototype, the X1.5, and are now progressing well through our next crucial phase of testing the hydrogen fuel-cell technology on the dyno rig. This stage is instrumental in maximising the performance of the fuel cell, an essential step before embarking on track testing” — John McKenna, HVS Chief Technical Officer
The test vehicle serves as a critical tool for the development of the propulsion control strategy and the vehicle software for future builds. Each subsequent prototype vehicle will use the learning and data points from X1.5’s tests, ensuring a fully optimised drive system and the highest performance levels.
In reaching this testing milestone, HVS are again demonstrating our ability to develop our ground-breaking products at pace. This is another firm indication of the significant progress we are making in bringing our revolutionary zero emission vehicles to market. Following the X1.5 dyno rig testing, HVS’s track test vehicle X2 will complete its commissioning, ahead of being put through its paces on the track at the start of 2024.
