Four engineers made an electric range test of Tevva's dual-energy truck prototype, which they used to test the hydrogen-electric truck. Tevva is still focusing on building and delivering its 7.5t battery-electric vehicle, but it is also testing and developing its hydrogen-electric counterpart at a fast pace.
Four engineers from Tevva, Charlie Cordell, Byron Dolman, Ryan Clark, and Toby Hurst, recently did just that with a "range test" of Tevva's prototype dual-energy truck. In the 7.5t hydrogen electric vehicle, the four people drove more than 1,000km (about 620 miles) between Tevva's London headquarters and the Scottish border at Berwick-on-Tweed, the largest city in northern England.
On the way back, the Tevva truck drove nearly 350 miles without stopping even once to charge up. This was possible because the hydrogen fuel cell in the truck could recharge the lithium battery in the Extended Range Vehicle (Rex) when it ran low.
Charlie Cordell, who is the chief engineer of Tevva Rex, said: It was a great trip, and we were glad that the truck could cover so many miles on the way back without having to stop and fill up.
The trip was a great example of how self-sufficient a truck can be when it uses a mix of electricity and hydrogen. The freezing weather made things very hard, but it also helped us gather important information about how the vehicle worked, which meant we could make changes here and there and move forward.
During the trip, the temperature rarely went above freezing, and at one point, it dropped to -10 Celsius.
