In addition, Viritech will lead development of Type 5 hydrogen pressure vessels. These are not yet commercially available, but offer the prospect of a significant weight reduction, thanks to the removal of the inner tank liner currently used to prevent leakage.
Viritech’s Graph-ProTM pressure vessel solution will be manufactured in the UK, and developed for volume manufacturing as FCHEVs become mainstream later this decade.
In addition, Ford will test Viritech’s revolutionary Tri-VoltTM hydrogen powertrain ecosystem. Tri-VoltTM represents a radically different approach to the architecture of hydrogen fuel cell powertrains. Unlike other systems which use fuel cells to charge batteries to extend their range, Tri-VoltTM uses the fuel cell as the prime mover when a vehicle is at a steady speed, and uses very small, high C-rate batteries to manage power during transient conditions (e.g. pulling away from rest or braking). High C-rate batteries are able to charge and discharge far more quickly than conventional batteries and produce much more power for short periods – e.g. a 6KWH battery pack can produce up to 600KW for 20-30 seconds.
The Tri-VoltTM eco-system is a combination of hardware and software, and includes an ultra-high-performance DC-DC Convertor with an HV bus connecting the fuel cell, battery pack and traction motor. This integrates these components into a single system, removing the need for separate DC-DC convertors for the fuel cell and for the battery pack, saving significant cost and weight.
Timothy Lyons, CEO of Viritech said:
We are delighted to be part of this hugely important research project. Believing that FCHEVs will play a vital role in decarbonising commercial vehicles, and that they will become a vital contributor to Sustainable Transportation, Viritech is proud to be at the forefront of the development of this critical technology. We are especially proud to be a key contributor to this important project with the manufacturer of the world’s best-selling cargo van. This will be a major demonstration of Viritech’s ground-breaking technology and an important opportunity to demonstrate the efficiency and relevance of FCHEVs.
