People often think the Motor is most important part of EV racing - WRONG
Due to the fantastic support of Phil Eagleton at Voltsport & Ian Goodman at ENRGmotorsport, plus our WarHorse (prototype) - we now realise that Batteries, Charging & Controls are the most fundamental part of a successful EV. Particularly for our application (which should use >50% of the battery in a record run). Our Peak Speed is measured in middle of a 4 mile round trip. Shorter than track racing, longer than drag racing. These are where most of the worlds EV knowledge has been developed - so we're unique (in more ways than one!). Launch is 1.2 mile from the pits. It's 1m back to the lights, but we go off very steady. We take ~2mins to build, & need max power for just the last 15sec. Then there's a looong time slowing (& another mile back to the pits). This vid is Trojan, from ~1/2m into a strong run. |
Batteries on WarHorse-E are temp limited, mainly during charge (but on the edge in a run if we start with them too hot). After 20sec's we've found that full power drops. This is protection from our Battery Management System, but by building gradually, we learnt how to 'drive round' this limit - and added 5mph to our max speed. |
