"Smart" Home Charger by Blink

I have just ordered a Model S and have been making preparations at home. Blink already provides chargers in commercial locations and is coming out with a home charger this summer. They refer to it as a Level 2 charger. (blink.com)
Can anyone give me thoughts on the best set-up for home charging?
Can't wait for my Model S to arrive!

No need for an expensive charge station. A simple NEMA 14-50 outlet is what most people have.

Don't waste your money. Have an electrician install a NEMA 14-50 (240V) outlet and you are all set.

:-) Douglas beat me to it:-)

mradin,

Your car already has the charger on board. You don't need another. Blink is for other cars that aren't as cool as yours.

I got a Blink through the EV project for free about 18 month ago when I got my Leaf. They have had home chargers for quite a while. They too got subsidies to develop a charging network by giving these away if you agree to allow them to monitor your usage. Look Ecotality to see if they are still giving those away. You might be able to get one for free, you just have to pay for installation.

I don't know the new capacities, but the NEMA 14-50 will provide 40 amps, which is 10 amps more than my blink (30 amps). And like others mentioned, the mobile cord (UMC) will connect to a NEMA 14-50 receptacle. This is probably the cheapest option.

One inconvenience with using the UMC is that if you want to keep it in the car to have "just in case", you'll have to remember to unplug it and put in car after every charge. That is unless you buy another UMC. Then for that money you could purchase the Blink or many other on the market, or even pay for the HPWC.

Eventually I will buy the HPWC, for convenience of not having to unplug my UMC and put it in the car after every charge.

Something to consider...

Good Luck

Is there a way to connect to the Blink without using Tesla's cable or adapters?

Yes, the UMC comes with the adapter for "public" charging stations, which is what the Blink and most everything else (minus Tesla) is equipped. (You can see it on the adapters page under Model S in the Buy stuff section of the website.

I am using the blink at home for over a month, until I can get my NEMA 14-50 installed in my garage. I use the adapter every day and I have used it at Nissan for the Tesla to get me out of a bind one day. Very handy gadget that comes with your car.

Oh sorry, just read your question more carefully.

You must use the adapter. Sorry for not reading better.

I haven't heard of third party Tesla charging connectors that you could wire directly to the Blink or other charger.

@jbunn, just to clarify, the Blink is not a charger either. To my knowledge all EVs these days have chargers on board. The Blink, the HPWC the UMC are only providing AC power for the charger (rectifier) to convert to DC.

The Blink is a permanently installed version of the UMC and HPWC, but most likely with lower power capabilities.

However, I do agree, no other 3rd party equipment is as cool as the car.

@mradin, my opinion, if you are going to pay the money to buy the Blink, pay the money to buy the HPWC. You can size it for the size charge you want to. If you pay for the Blink and want to go higher(charging capability), then you have to rebuy something else, on money into the Blink is sunk.

And to reiterate as others mentioned, the NEMA 14-50 will most likely be the cheapest option. The receptacle is less than $10 from home depot. The cost is in the installation and permitting.

@bt77057 - Buying an extra UMC is much cheaper than buying an HPWC. I bought one on the Tesla online store for $650, a little more than half the cost of HPWC. Since I didn't see the need for twin chargers, the HPWC would offer me no advantage, and other than looking cool would do no more for me than the UMC. I recommend others consider the same if they want to have a charger with them at all times.

"for convenience of not having to unplug my UMC and put it in the car after every charge."

But you would still have to remember to take the adapter.

An extra J1772 adapter is $95. I agree on the NEMA 14-50. It's what I've been using since October. That said, I just bought an HPWC because we're moving to a house with no garage. Parked outside (and in the city), I want the added security of having both ends of the cable locked.

The HPWC also provides higher capacity cabling than the UMC, which will result in lower power losses while charging and less heating of the charge cable. So it should improve your overall charging efficiency, and result in a slightly lower electric bill.

So it may still be worth getting an HPWC instead of a second UMC if you plan to always leave the first UMC in your trunk.

@mradin@yahoo.com

First you only need the NEMA 14-50 installed. The car already comes with the UMC and the J1772 adaptor.

@joehuber

I have minimal heat build up in the UMC cord charging at 40A.

If you have a twin charger in your car, $1,200 HPWC is a good deal.

It requires 240 Volt, 100 Ampere circuit to charge your car at 80 Amperes (20kW) at 62 Ideal miles per hour or less than 5 hours to fully charge your 85kWh battery.

The Blink HQ Smart Charger is NOT a smart choice if you have twin charger car.

The maximum it can do is 30 amperes which your car may get 24 amperes or 5.8kw or 18 Ideal miles per hour or almost 17 hours to fully charge your 85kWh battery.

A 30 amps is 30 amps. You might be confusing circuit protection of 40 amps which allows charging at 30 amps. Assuming home voltage of 240VAC then you would be able to charge at 7.2kW, not 5.8 kW

My opinion: I agree I the HPWC is probably best choice overall. If I wanted a slightly cheaper option, I would buy second UMC rather than Blink. Install costs for the Blink or NEMA 14-50 would be of same magnitude. the NEMA 14-50 might be slightly higher for UMC option because of wiring required for 50 amp circuit. But like I said, that's my opinion...anyone's particular circumstances will be different with different priorities.

Good luck.
