PS: you have to go through the link to the Futura Sciences thread to understand.

The conditional is only articulated around “applications”.sicetaitsimple wrote:"Ultrafast" recharging is the promise of graphene batteries, could nevertheless be of interest in a number of applications (city buses for example). Wait and see.

It's not even the wiring that poses the most problem, but the ability to supply power ... We had already talked about it ...
A thermal car that fills up with 50 L in say 2 minutes is an energy of: 50 L * 10 kWh = 500 kWh ... and a power of 500 * 3600/120 = 15 MW equivalent...
Corrected by the respective yields, it would take a power of 15 * 0.3 / 0.8 = 5.6 MW to recharge an equivalent electric car (same range, same energy consumption) in 2 minutes ... and therefore 560 kW in 20 minutes .... and 190 kW in 1 hour ... 19 kW in 10 hours ... etc etc ...

Not a great mentality ... am I wrong?
