When Formula E began, the concept was to keep costs low by strictly regulating every aspect of the race cars. Same chassis, same transmission, same motor, same battery control system, same brakes, and same tires. The idea worked brilliantly. Formula E is the fastest growing auto racing series in the world with a waiting list of world cites anxious to get on the calendar.
But Formula E is slowly relaxing the rules to permit the teams to innovate and what could be more innovative than using a flow battery when everyone else is using a lithium ion battery pack? That’s what Swiss company nanoFlowcell wants to do. It is in negotiations with Formula E and the FIA that would allow it to field a team powered by its proprietary 48 volt flow battery.
