Setting timer for charging

I am part of a charge rewards program, so I needed to create something.
Since the smart electric does not have a built in way to set charging times, I created a relay box.
This relay is powered by a small 12v transformer to make the 220V connections.
This system can also be used to allow time usage charge, Electric bill cheaper at off peak times.


The 12v wall transformer is being controlled by a home automation socket that can be set on a schedule to turn items on and off. This has allowed me to turn charging on after midnight nightly while I sleep.


Hope this helps someone setup timed charging at home.

Yes that is a big problem, if you do not have a home charge situation don't own the EV.
Unless you have nearby chargers or workplace charging, buy gasoline car.
These EV cars are leaving out millions of people in multifamily housing.

Setting timer for charging

Luckily, I have a 240v charger only about 2 blocks away (3-4 min walk). Also, itís free, so I havenít spent a dime on electricity since I bought my 2014 electric (bought it only 6 months ago).

Wow. Good deal! Curious - is it in a public parking garage, the parking garage of a friends apt. or condo, shopping area etc... I am asking because if it is in public setting, you have to be careful about observing charging etiquette...

It is a public place (a bank). But I always check in on PlugShare, saying that anyone can unplug me if they need to. Also, I only charge when I need to and only from 6pm onwards.

I would have thought that most level 2 EVSE units for home use have this capability.

I use the open EVSE kit-built unit that has this capability.

But I sure miss the now-discontinued Smart vehicle homepage utility that allowed me to set the pre-warm departure time from the warmth of indoors...

I just use a 220V/120V evse plug with no brains.
Just installed 220V next to driveway, most of the time I do not leave cord outside, had one fail because of water.


Just posted this in case someone needed a way to time their plug.
I can also turn off outlet when not in use, for safety and power usage reasons.
I can over ride timer any time

So, true
Or people who don't have a garage or one with electricity or a plug close to the street. Then are you going to leave your car charger out and unsecured in the open.
The charging cord for my Volt is only 20 feet long.

Many people have chargers near work and can get home and back to work on a charge.
I could but charge to 100% anyway just in case lot is closed or charger cannot be used.
20 miles takes me 2 hr charge, I do 12 hr shifts so 2hrs is easy.
I would not own an EV in the northeast without the ability to charge at home, many days when I do errands all day I charge when home a few times then go out again.
I have put 17k miles in one year on my 2013 Smart




I get bonus points for charging at night and get paid monthly to charge off peak.
