Panoz unveils all-electric GT project for Le Mans
I love this to bits.
I've been advocating dual battery chemistry setups for performance and economy gains for a while. Until a chemistry hits the market that gets bot great density and really high charge rate (for regenerative braking), it's the way to go.
80-90% of the battery mass could be in a high density chemistry that offers decent power output, the rest is a high power battery with just a few kWh.
The small power unit takes care of regenerative braking (hundreds of kW extra for a number of seconds), and fast acceleration out of course to reach cruise speed.
The bigger "slow" range battery maintains cruise speed (I suppose 200kW suffices to make that car go 180mph/290kph), and funnels some energy to the fast one to be all ready for the out-of-corner sprint.
Next season, Formula E will do a whole race on one charge. Imagine adding a bit of body work for lower drag, actual wide slick tires, and a small power cell battery. It's very doable and frankly by now it should have its own race class. Set a minimum and maximum weight, crash test requirements, freedom to mix chemistries, and go crazy!
