EESUs Make Electric Cars Easier to Own
Ever thought about owning an electric car? For anyone who's nixed the idea because of the 5-6 hours it takes to re-charge batteries on long trips, Texas-based company
EEStor has some good news.
The company manufactures the EEStor ultra-capacitor (or EESU), a quicker-to-charge, lightweight battery that is faster to charge and easier to use than regular lithium-ion batteries. And unlike lithium-ion batteries, EESUs can be charged and recharged over and over without losing life.
This article on Edmunds explains:
"To put this in perspective," says Paul Scott, co-founder of Plug In America, "I drive an electric Toyota RAV4 with a 1,000-pound battery that is capable of holding 27 kWh (kilowatt-hours) of power. I could replace my battery with three EESUs, weighing a total of only 300 pounds, that are capable of holding 45 kWhs of power." The additional power and reduced weight would more than double the vehicle's 120-mile range and it would recharge in a matter of minutes off 220 volts, slightly longer when using household 110 volts.

What I don't get is "...would recharge in a matter of minutes off 220 volts, slightly longer when using household 110 volts"
If Power (Watts) = Amps x Volts, then
220V x 30amps = 6600 Watts
Doesn't this mean that it would take 45kWh = 45,000 Watt-hours/ 6600 Watts = ~6.8 hours to charge?
To charge in "minutes" would take a LOT more amps and/or volts, right?
