I'm so glad this is an issue or a concern... Never thought electric cars would escape the clutches of the "Big 3."

Gorski, I'be also wondered about installing fast chargers at gas stations. Because it would take longer (20-30 minutes per charge as opposed to 5 minutes to fill a gas tank), I presume a filling station would need more slots, and therefore more land. Wouldn't it? Imagine how crowds would build up at your local gas station if it took 30 minutes per fill-up.

Naperlou, the 150-mph nomenclature is a kind of shorthand sometimes used by the people who make chargers. It refers to the number of miles of range you can get per hour of charge. It's a little unusual and will obviously vary from car to car, but it provides a general idea of speed of charge. At 150 mph, you could recharge a Leaf battery (73-mile range) in about 30 minutes.

as the market finds new solutions and cheaper installs, we can see the infrastructure growing.

 

I'd love if Starbucks would install fast chargers at al their stand alone stores.

 

it's growth like this which has me convinced EV's will take over the car market

in 5 years.

a wireless charger would be good for electric city busses.  Put the chargers in at major stops, let them recharge, a bit,  and then plug in where the mechanics can handle that at end of shift.

150 MPH recharge rate,  typically most EVs get 3+  M/KWH,  so,

figure that's some 50 KW charger.

 

it's probably closer to 45, but it's a ballpark,  now bear in mind that's a average for what is a declining balance charge rate.  if you charge to 60% it's high power, at 60-80%, it's usually reduced power and the last 10% is low power.

 

it's why the tesla superchargers slow down too.

I think you show some very interesting battery chargers that should instigate some thought. The cordless charger would be fine for a home and a paid parking space at work. The "manhole" chargers could be financed by the company receiving goods from a truck. A good idea would be to have "fast chargers" at gas stations. They exist and are intended to dispense "fuel." The fuel could be electricity or gas. The short charge time could be used to sell something, offer a coffee break or make cell phone calls.

On slide one you talk about "150-mph" recharge rate.  What is that?

I notice that on slide 10 you have a home charger for $2,000.  That seems to be a lot.

I like the wireless charging systems, but how much would it cost for a home system?
