How long does it take to charge? Granted 350 miles is a long trip, but some 9f us drive from Seattle to San Francisco and we can't do that in 350 burst waiting overnight for the car to charge.

Personally I think a hybrid that plugs into 120, with a commuting range 50 miles and a back up gas engine will be the sweet spot



Lithium-ion batteries can be fully charged safely in about an hour, give or take, regardless of their capacity. 80% charge is about half that, IIRC.

The reason it takes a while to recharge EVs is because of the enormous size of their batteries. Tesla Superchargers inject more power into the car than what comes into a regular home.

Quick math: A 100KWh is going to take a bit more than 100KW of power to charge in an hour. For comparison, an oven uses about 3KW...


You can get back 120 miles of range in 20 minutes. The M3 I believe is even faster.

Range is no longer an issue for modern electric vehicles.
