Electric Vehicle Charging Station (EVCS)

[apdb]

With the rising popularity of electric vehicles and charging stations being installed in peoples homes, I wonder has anyone been pondering what it would take to get your EVCS to talk to your electric controllers for your boiler. Has anyone here been thinking about what sort of challenges would need to be overcome. It would be nice to get my boiler out of the kitchen (stove plugin) and into the garage.

Love to hear if someones also thinking the same thing.

Way easier to just make a super simple controller and plug it in instead of an evse. The control signal is in the car, so you would need to get a socket to match the plug and create a circuit to duplicate the car charge signal to make it work.

Also evse’s are expensive. Mine ran $500 for a 40 amp. I can build a controller for $50 or so. I did run a 50 amp circuit which has a plug in the garage.

Mine came to $600 in a new home after permits and install. The trick is how hard would it be to build a small device to go between my already built controller and the charging unit thus getting me out of the kitchen and into the garage. A question for someone waaay smarter then myself.

Short answer, you wouldn't. It's simply not worth the complication and risk that you might damage the EVCS.

If you don't want to run a second line for your still, consider installing a sub panel in the garage, and then break out separate circuits from their for the EVCS and whatever else you need.

If you already have a evse and controller, why can’t you plug the controller in to that outlet? I can do that easily. If you are hard wired, it’s probably easier to put a plug in the middle that build a circuit to duplicate the cars signal required to turn on power in the evse.

Seems to me the simplest solution is to piggy back an outlet for your boiler controller off of the circuit for your EV outlet (not the EV outlet itself), just never use both at the same time.
It wouldn't be to code, but 99% of safety is common sense.

Basically what I said above, but having a separate panel is to code and more flexible.

i agree a sub panel is the best solution. I put a 125A sub panel in my garage when I bought my house, the 80 ft cable to power it was quite expensive. I was merely suggesting using the seldom used circuit (for the EV charger) for another purpose while the EV charger is idle. If I hadn't installed the sub panel and had an outlet for my old stick welder instead, I could add an outlet for the boiler off of the welder outlet and it wouldn't be any problem as long as I didn't weld and still at the same time. That is where the common sense needs to be applied

If you use the SAME plug-in outlet you can NEVER use both at the same time.
An extra safety measure...

For safety better feed it from a GFCI breaker then.

Sounds like the best answer to me Geoff
