Re: Tesla cars
The "superchargers" are DC: they bypass the built-in charger. Others are, as I understand it, glorified extension cords. You can trickle charge from an ordinary wall outlet if you have the right cable. The car knows what kind of cable ("charger") is hooked to it and adjusts its demands accordingly.
There is more to these "chargers" than just wire, but they aren't chargers in the same way that a 12 V battery charger is.

Re: Tesla cars
I live in a small town, half way between Portland OR. and Seattle WA. about 80 miles either direction. Off one of our exits we have a series of Outlet shops and food franchises. There is a Tesla charging station there, that can charge a number of cars. Maybe a dozen!? I will take a picture some time soon and post it here.
Live for the moment!
Prepare for tomorrow!

We know that electric recharge station well. It marks the turnoff to our favorite travel food stop: La Terasca.
During our trips to and from Seattle, Centralia offers the BEST lunch stop at La Terasca, a family-run Michoican restaurant, next to the first set of RR tracks heading east from I5.
Totally gluten free, our entire Celiac family stops there during travels. It's good to find a place that won't kill us!
I always think about you and Harold being nearby when we drive that way.
Some day we'll meet...

Re: Tesla cars
My door is (*almost) always open to visitors, so don't hesitate to stop by if you have the time. Advance warning could even result in a fresh baked blueberry pie and a cup of coffee.
One word of caution.
*Susan and I are night people, so our sleeping hours are a bit strange. We get to bed around 5:00 AM, and generally sleep until noon, or shortly thereafter. Therefore, mornings are never a good idea.
No, I don't know why that is, although my biorhythms have ALWAYS (since I was a wee lad) mandated that I'm a night person. Susan is worse.

Good thing you two found each other! Coulda been a problem, otherwise!

Re: Tesla cars
Back to the cars. The Akron (Ohio) paper noted this morning that the Ohio Turnpike Plazas in the western counties have added charging stations (for electric cars) with the further comment that they charge faster than the ones at home.

Re: Tesla cars
Fwiw ...
I followed tsla quite closely for about 3 years, starting from expecting them to be a useless joke, before knowing anything about them.
What tsla does better than anyone else is;
1.
- the vfd electric drive for the motors.
Mass == 30 kg, cost == 500$ marginal, 300 kW+ peak, size of small oven, efficiency about 96%.
1.1.
Better on the new Model 3 variable reluctance / partial PM motors and new power module unit also doing 12V DC aux functions.
2.
Recharge via VFD/motors.
Faster and more efficient and better sw than anyone else.
3.
Good fast home AC charging including 3 phase AC home charging (EU) on older Model S cars, and likely on all new models.
Old S cars had 22 kW home chargers (EU, 3 phase, very common, very cheap).
We don´t know about Model 3s yet.
I believe current Tsla models home charge at 16 kW+.
The Bolt is a pathetic 7 kW.
4.
Fast DC charging.
Ex-tsla there are a tiny nr of shipping cars barely able to charge at 50 kW, and we don´t really have any real good examples of these working in scale.
Tesla has been fast DC charging at == 118-120 kW for about 4-5 years.
5.
Battery longevity, mass, energy density, cost.
5.1.
Tsla leads the best nearest shipping competitor the Bolt battery by 5-8% in energy density and about 50% in levelized cost.
Tsla is == 200 kW/kg in power/mass by system, not cells.
Tsla leads the best-in-the world competitors by about 100% on a blend of critical factors from size, packing, balance, costs, longevity, reliability.
Tsla currently delivers about 60% all ALL global EV battery packs in light vehicles, by kWh or total energy capacity.
Current tsla run-rate at 10/2018 is about 24-30 GWh/yr on shipping BEV cars/SUVs (Model X).
This is increasing over 100% y/y exponential.
Tsla has about 10x-100x more miles of experience on full BEV cars than anyone else in the world, and this is experience is growing faster than the deliveries of anyone else in the world.
The Nissan Leaf series has delivered more cars than tsla, but due to a tiny battery the average miles / km used are very low, and thus the tsla fleet is very quickly outdistancing it by kWh and by miles used.
The current best-selling Model 3 will likely overthrow the Nissan leaf sometime in 2019 by total units, maybe Q4/2019 == 450k units.
Now in 10/2018 the leaf has sold 320.000 units and likely will be about 400-450.000 by Q4/2019.
At this time the Model 3 is sold at about 18-20.000 units/month and this will likely become 6-8k/wk within 6 months+ reaching 32.000+ / month around Q2/Q3 / 2019.

Re: Tesla cars
I recently found a charging station at one of the coast casinos. I also heard a police department in California has bought a Tesla S.
