Home CHAdeMO

I was looking around for fast charger options. So far it looks like the home CHAdeMO units are limited to 40 amps of 240v single phase.
I am putting a 100 amp sub panel in the garage my self, probably on 2ga copper so I can run my miller model 250 welder at full power, which is around 340 amps for welding aluminum. I don't use the welder every day but I will be using the car charger circuit every day, maybe even multiple times a day.

Here is one I found:

So with the AC 'charger' stations, they take care of the switching and making sure that there is actually a charger on the other end, but you still need to take the AC and make DC (with a charger) for your batteries - right? And take care of the voltage regulation, and when the batteries are full.

Alternately, the 'DC' charger stations put out a voltage and current as controlled by the vehicle (via communications) and terminate the charge when the vehicle says so?

My battery charger won't do anywhere near that amount of power, so I have not investigated a whole lot as yet.

My handy wall chart (old version) lists #2 as 100 amps for a 60C rise. The new chart lists 110 I think. Either way, #2 is good for your 100 amp feed.

The J1722 which is your level 1 and level 2 charger is a fancy extension cord with switch controlled by the vehicle. It sends AC power into the vehicles built in charger.
The CHAdeMO makes DC and sends the appropriate high voltage DC power to the car and it would seem that it sends it pretty much straight to the battery. The vehicle controls the CHAdeMO unit.

Another one, 12kw.
http://www.electway.net/product/12KW...ctric_car.html

A 20kw single phase unit for $7,500
http://store.evtv.me/proddetail.php?prod=20kwchademo

I actually could get 3 phase power if I wanted. My well had a 3 phase pump. The transformers for the well are still on the power pole just have had the 4160v line fuses pulled.
If I ever did get 3 phase power ran to the house I wouldn't want 480v 3 wire, I would get 120/208v 4 wire configuration.

That's half of what the car cost, do you really need to charge that fast?

If the demand is there these units will come down in price.
I would really like to get one, but I also really don't want to spend any where near $3,000 on it.

Cool. Our electrical system only supplies single phase to residential (Canada). There is only 1 feeder coming from the distribution transformer in my area to the house transformer. SaskPower will bring in 3 phase if I pay for extending the other 2 phases to my property, and pay for the three phase transformer, but only if I can get my property re-zoned to commercial.

The electrical inspector tells me that it is illegal for me to 'make' 3 phase out, using a controller, to drive pumps or other loads.

But I can have 600V DC off a solar array on my house, and if I don't grid tie ... I don't even need an ELECTRICAL PERMIT. Anyone can claim to be a solar installer, dig holes in my roof, hook up high voltage DC without being an electrician .... what a system!

I would like to keep it single phase, 240v that can go on a 200 amp service.
Like you said not everyone can get 3 phase as easy as me.

Thingstodo So with the 600vDC you aren't allowed to convert it to 3 phase? Or you are just not allowed to convert single phase grid to 3 phase?

If you don't have 3 phase service there isn't any point in running a 3 phase inverter.
