If we can have Hybrids which are petrol with small batteries which will go for say 30 miles and then switch over to the engine which will then re charge the battery, effectively say at 80% petrol 20% battery a lot of the time. . Then why can’t we have EV’s which effectively reverse that and use the batteries the vast majority of the time but also have a small back up engine which would have very limited capacity to recharge the battery but could be used as a backup which would be easier and a lot quicker to fill up in emergency or doggy circumstances where you EV battery may be in danger of running out in a long journey and in which you have less choice in finding a EV charging station. I know it would be extra cost, but in cars that are costing 40 to over 50 thousand pounds anyway.
Of course, these already exist @Callmejohn Nissan Qashqai ePower, Renault Austral, Mazda MX30 RE, use electric power to drive the wheels but are charged by a small petrol engine and are available on Motability. The Honda Civic uses similar technology but for some reason is not available on the scheme.
Thanks 72 dudes, that will save me wasting my evening trying to Patent that idea lol.
