I picked up a Chargepoint home at an auction. I looks brand new but didn't come with the J1772 cord. My gen one EVSE crapped out sometime ago, so I was wondering if I could use it instead a buying one from Chargepoint.

Hope you can help.

Thanks

The Home comes as a 16A or 32A model. Which model do you have? What gauge wire is in your J1772 cable?

 

[MaxVoltsOhio]

It is the 32A. But either way it is still 16A per L1 and L2. I probably have that wrong but it is what I was thinking to myself.

The original EVSE was designed for and is limited to 12A. The Gen1 will take a max of about 13.75A when connected to an L2. However, unless you can set the max current advertised by the EVSE to something lower, hooking up a vehicle to your EVSE that has the capability of taking 32A, might produce a nasty outcome with wiring that probably isn't safe for that current. I'd suggest selling the old EVSE for parts on eBay and use the funds to buy a quality, high-current J1772 and cable.

Not sure about the ChargePoint model, but perhaps it lets you set a lower current limit. If your J1772 cable is 14AWG, 16A is ok, but definitely not 32A. Of course, the Volt will never draw more than 16A, so you're ok, but you'd never want to plug that combination into a Bolt-EV.

Some cords are only 16AWG (2016+), if so, I wouldn't do it. Should limit current to 12A in that case.

I will just buy the one from chargepoint. The stock one has five wires and the chargepoint only had 4.

car is only gonna draw what its designed for,,you can have a 1000amps capabilty,car is still gonna take 12-13amps.Its like your fuse box.you can have a 50 amp dual throw for your oven,but the oven only draws 30amps.

That is true, but by code you cannot put a 30 amp wire on a 50 amp breaker

If the EVSE is capable of 32 amps and you can't dial that down to limit it (the EVSE) to 16 amps or less, you should never put a 14 gauge J-1772 cord on it. One day down the line, somebody might plug it into a car that can take 32 amps and THEN you have a BIG problem

Thanks all, deep down I knew that I shouldn't do it. Something about saving money made me ask. LOL New cord will be here Friday!!!!

Thanks again!!!
