Title: EV Charging
Post by: flannel on November 05, 2018, 05:24:19 PM
I needed a way to charge my wife’s new electric car and got a quote from an electrician to install a charging station in the garage.  Their quote was over $3100 including a new electric panel and increasing the electric service to the property.  I did some research and figured out that a 240v outlet could be run off the existing panel with a quick change to a couple tandem breakers with no upgrade to the service (already 300 amps!). Same charging capability, and doesn’t require buying special equipment from manufacturer.  $280, installed by a licensed electrician, and working great.   

Lesson learned: do research before paying more than seems reasonable.

$3100!!! Holy F***

Good work on doing your research and not being suckered in.

First guy was looking for a sucker. Glad he didn't find one.

Likely fishing for Tesla owners.  "Oh, yeah, I just dropped $100k on a car, I suppose a few grand to charge it is reasonable."

I need to mess with tandem breakers for my outdoor box.  I've got a couple 240V devices in there and am nearly out of slots.  The Volt currently charges on 120V/12A, which... actually, works well enough for now.  But I'd like to get 240V out there in case we upgrade to a pure electric at some point.

Ended up DIY on mine.  Turns out the “Heater” circuit was unused after the previous owner installed a natural gas system.  So I popped out the 60A tandem, and popped in the 25A spec’d breaker and routed the wires in via a box for the AC wiring.  Took about an hour and $20 of stuff.

I had planned to install a 240V outlet, but I’ve been finding it more than adequate to charge on 120V.  I can get 70km of range back in the evening and my round trip commute is 50km so I can gain ground over the week. If it’s really necessary, I can go work for an hour at a coffee shop where there’s a free charger that gives almost 40km of range per hour. I’m reconsidering whether it’s worth adding the  240V at all. There’s a good provincial incentive that helps with the cost, but so far I’m not seeing the need.

Good job avoiding that scam. I think a lot of people find charging the car a bit scary but it's not really that complicated unless you need a really long range vehicle.

We're using a 120V outlet every other night to charge my wife's car. She doesn't drive more than ~10 miles in a day, though. I generally bike to work. As a result, we haven't used more than 1 gallon of gas in the last month!
