I honestly doubt this setup would ever have any problem, aside from the risk of something else being plugged in to what appears to be 120 VAC and actually being fed 240 VAC. That really makes no sense, but that is where it is. I am trying to understand my own thinking here. Somehow, I am much more comfortable with using an adapter to operate the OEM EVSE on 240 VAC even though it isn’t labeled for it when it is used as an opportunity charger but not as an everyday solution. When I initially responded to this thread, I was under the impression this adapter was going to be used as the primary solution for day-to-day charging, not as just an occasional use when traveling. I need to clarify something as I feel like I have been disingenuous. Then, a few months in, I got an offer (a rebate) from my electric company, so I went and installed the Chargepoint. I had a 12 gauge Romex, I had the receptacle, I had some time, the only cost was the double pole breaker and the cover. with unknown of overheating.īesides, the 240 V 32 A EVSE would cost $500, which I did not want to spend. Or it would take 24 hours via 120 V and non-dedicated circuit. Well, I had 500e that could charge overnight via this setup. Yeah, it had a cover, red tape, and so on. The receptacle was a regular 15-Amp residential style, except it was at 240 V. I wired a 12 AWG 2+G using a double pole breaker and a dedicated receptacle. But I had gone even further into a MacGyver style. It is an adapter to use 220-240 charging without a huge investment.īesides, it is exactly (almost) what E-Ampera would have - same internals, but EVSE is plugged into a 240 V socket. Let me know if you have questions.Ĭlick to expand.Boys and girls and others. I had everything but the whirlpool dryer cord in my garage so it was quite fast and cheap to make for me. Here is a possible cord for the NEMA 14-50 outlet: Then add the outlet cover, mark it as a 220V device and you are done. Once you have really tightened the screws, push the outlet down and screw it into the device box. Just one on the left and one on the right. It doesn't matter which side each of the outlet the other two wires go to. The middle wire of the cord must be wired to ground (usually a green screw) on the outlet. Once you have them off, run the cord up through the device box and screw each wire on to it's respective screw. Removing the screws will take a little pushing, but they do twist off. Since the cord comes with circular lugs, you'll need to remove the three screws (ground, and one screw from each side of the outlet). The other two wires are screwed on to either side of the outlet. The middle wire on this cord is wired to the ground on the outlet. Remove the metal bracket on the end of the wires on the Whirlpool dryer cord. Once you have all four items, it is a snap to put it together. On Amazon I could only find a pack of 10 but you get the idea. On the cover, you can buy single covers at hardware stores and they can be had for less than $0.50. All can be found at hardware stores or Amazon. A 110 outlet,a construction or device box and an outlet cover. Once you have that, you'll need three other items. OK, for the 3 slot 220V outlets (see picture), first buy this (which you can also get at home depot for the same price). So if you have one of these 220V outlets in your garage or house, I believe it is worth the time and money to build one. The reason you want to do this is the OEM charger is 220V capable and will charge the Bolt at roughly double the rate of charging at 110V. Ill point out the cord for that one but won't describe how to build it (although it is pretty similar, you will ignore one of the wires and wire the neutral wire to the ground wire of the outlet). The newer ones have 4 slots and is called a NEMA 14-50 outlet. In my case it was a 220V dryer socket that had 3 slots (holes?) (also called NEMA 10-30R socket). What I am talking about is making an adapter so that you can plug your OEM Bolt Charger into a 220 V Dryer socket. One that can be created in about 20 minutes for under $20 and only a screw driver is required to make it. I know there have been a number of posts here on this topic but thought I would share my creation with you.
