We understand that supercaps are way low on energy density, but what about their power density?! It's HUGE!
What about their efficiency?, exemplary!
Lifespan?, one million charge/discharge cycles!
So.. what's going on then? Any ideas?
Benefits of incorporating supercaps in an electric vehicle ( in my humble opinion) are:
1. Increased lifespan of battery cells due to a flatter discharge graph line ( this also means you can rebalance energy vs. power when formulating your battery cell toward more energy, 100 kWh battery for the Model S or X is not far fetched).
2. Much more efficient regenerative braking ( supercaps' low ESR means that they will accept much higher currents than li-ion cells, especially when your electronics layout has a "Joule thief" configuration function, the vehicle will recapture 100% of its kinetic energy, all the way down to 0 mph, no friction brakes required).
3. A 1000+ hp quad-motor drivetrain is more than welcomed by the sheer power momentarily provided by the supercap modules)
I can go on and on about this, but let's stop at this much.
