Electric trucks pass freezing endurance test
Four engineers recently completed a ‘range test’ of Tevva’s dual-energy prototype truck. The exercise saw the foursome accumulate more than 1,000 km in the 7.5 t hydrogen-electric vehicle, driving between Tevva’s London HQ and the Scottish border at Berwick-on-Tweed - England’s most northernmost town.
The return journey saw the truck cover almost 560 km alone, without needing a single stop for recharging. This was made possible by the truck’s hydrogen fuel cell which tops up the range-extended (Rex) vehicle’s lithium battery when needed. Temperatures rarely climbed above freezing during the trip, and at one point it dropped to minus 10 C°.
By adding hydrogen into the energy mix, Tevva’s solution gives operators the ability to decarbonise their fleets. (ben)
