I've been using this set-up for three years, and it works great.

I just did it. I installed a 240 volts, 20 amps outlet in my garage, connected to 2 phase 20 amps circuit breaker. Then I made the adapter 240v to 120 outlet in the same way as described in this video. It's working right now. The OnStar report on my cell shows it as connected to a charging station. The full charge is predicted to take only 5:45 hours as opposed to some 14:30 hours. I confirm that the cable is slightly warm but it's really nothing to worry about. Note that I was an electrician for 10 years in a past life. So, I knew what I was doing. A huge thank you to Green Mountain DIY Guy for sharing this information. You essentially saved me $400.

True, but the stock plug has a thermal sensor that provides some protection. I find that to be a nice feature.

Another way to be safe would be to have a 120v duplex with both jacks of opposite phase and then fabricating a 'Y' dongle using 120v plugs and one in-line jack. Everything is still unmodified and usable in 120v except for the 'Y' adapter that can supply 240v when needed.

The wire gauge and how much it will heat up depends on current, not the voltage, the drop will be the same for the same current. Since the current at 120v is also 12-13 amps, there will be a warming at 120v the same as 240v. In other words, I wouldn't worry about that since the cable is designed to handle the 12+ amps that the charger pulls. You can also reduce the current in the Bolt interface, limiting it to 8 amps if you are concerned about the load. You would still be presenting a faster charge, about 30% more power than 120v @12A.

You could get a 120/240 adapter as well right? That way you could use the same cable for 120 or 240??

I wonder if both 240 hot lines are switched inside the charge unit. I hope so, because if the 120 v. design didn't switch the neutral you'll have one lead always hot out at the plug (even if it's not plugged into the car.) I modified a 2013 "charger" but it required disassembly to route both power leads through the double-pole contactor. A DIY was on YT somewhere for the earlier ones.. May still be.

Australia with 240 volt standard means all Holden Volts charge on 240 volts. Not sure if they are limited to 8 amps however...

no modifications are necessary just hook 230 volts to a 110 volt wall outlet. Take the power leads going to your central AC unit and attach them to a receptacle. You could replace the plug on the charging unit or make an adaptor and use a 220 volt receptacle if you wanted to prevent someone from plugging in some other 110 volt plug into your 220 volt receptacle.

Correct. The L630 carries two 120 volt legs and a ground. There is no neutral with this plug. When I first wired a few years ago I was confuse as there was no neutral. Found out that a lot of 240 receptacles don't typically use the neutral wire. The L630 runs to a sub-panel in the basement that terminates to a double pole 30 amp breaker. Wiring is 10 gauge from the sub panel to the L630 receptacle in the garage (to which the EVSE and adapter plugs into). The Chevy Volt EVSE/charger auto senses voltage and knows if you are connected to either 120 or 240. Now that the charger is only drawing 12 amp, my 10 gauage wire is oversized and will very much act in the same manner that you described when going from 10/3 to 8/3.

You mentioned that the OEM cord (from the charger to the car) got 'warm' when you were charging at 220V and drawing almost 25 amps through it and you said you'd have to keep an eye on it. What happened with the OEM cord? Did it 'just' get 'warm' and not suffer any damage or change to it's structure? Would that OEM cord survive hundreds and maybe thousands (365 per year) of charge cycles without catching on fire or burning out? Did you have to replace the original cord with a thicker gauge wire? Is it possible and safer to find a way to replace that original cord with a thicker gauge cord which is able to carry the higher voltage and amperage? Please let me know. Thanks.

I've never even taken the included extension cord out of its original packing in the trunk. My biggest complaint on the new Volt is that Chevy used a 3.6 kW charging circuit. My 2013 C-Max had that charging circuit level and took considerably longer to charge at the same volt/amp levels than my friend's 2013 Honda plug in with the same size battery but a 6kW charger.

The "dryer plug" or whatever plug you need to fit your 240v outlet has 3 wires, ground and 2 hots. The 2 hot wires are two opposite AC phases each have 120 V RMS peaks. Bothe peaks occur at the same time and so give 240v. It makes no difference where you connect these as long as it's NOT ground. Just connect the wires (usually black and white) in the cable. The other end is somewhat problematic. Female receptacles that fit the charge plug will only be rated for 120V. The voltage rating is partly because of the application (only 120v usually) and also affects how the internal dimensions are designed. Generally 240v things have greater distances between the terminals than 120v things. When you look for the female end your only option will be for 120v. Get one that says 120v and 30A and you will be ok.

Why doesn't some company make a simple adapter that you can just plug the charger into and then plug the adapter into your 240V outlet?

I'd assume that factory made level2 220 charge cords would all have thicker cords but that would be for vehicles that have higher Amp internal chargers ...?....

The opposite is true: Higher voltages can use thinner wires for the same amperage. Since we are limited to a maximum of 12A either way, it should be cooler. I don’t know why his cable felt notably warmer in the video but perhaps he normally charges at 8A with 120v to avoid melting the outlet. With 220v that is no longer necessary.

Asking for a wiring diagram disqualifies you from this project, sorry

Im about to do this mod, but since i'm running it to my garage and it'll be at roof level, my plan was to simply run the 2 phases into a 5-15 and skip the adapter. No one can reach up there without a ladder so i dont see any chance of accidental plugin, i'll probably put it inside a locked box as well to be even more careful.

I have a 10-30r outlet. So do I just wire the 2 hots to each pole of the 110/15? and then the ground to the ground? I was going to just buy a dryer cord with the 10-30r already installed. But they don't really label the wires and they're all black. So how do I know which one is which? Do you have a photo how you wired the 110/15? Also I was going to get a 20amp outlet to wire this to, do you think it's overkill since the Volt will never pull more than 12amp?

@GreenMountainDIYGuy

Mike Colburn correct, wire the two hots to each pole and ground to ground. Be sure to get the best 115/120 receptacle you can find. I went with a 20 amp receptacle as I believe they are better built. Sorry, I don’t have a picture, but pretty standard wiring. Feels like you are wiring 220/240 receptacle but in actuality are working on a smaller standard 115/120 plug.

@MikeColburn

vtmaestro I have since discovered that the 10-30r is 2 hots and a neutral, no ground. Apparently there is a way to ground through the neutral to your dryer. But I'm not going to a dryer. I was thinking to ground the 15-20 to an existing 15-5 that sits right next to where I want to put the new outlet. Is that acceptable? I would just put a 2 gang box in place of my existing one and wire everything inside that

@GreenMountainDIYGuy

6 жыл бұрын

I do not see why you cannot use the white wire to go to ground and keep the two hots? If you are coming off a sub panel, then the neutral and ground should be isolated so there would need to be some charges in the sub-panel there. If you are coming off the main panel, then the neutral and ground are most likely bonded. I cannot say what is acceptable or not. If you do not have knowledge of what to do, then please consult and use a licensed electrician. As indicated in my video, I take no responsibility for doing this right or wrong. Every setup is different. Want to be helpful but there are serious risks when working with electricity.

Again I am asking this question, hopefully someone can answer it :Can I replace my dryer L630 receptacle or whatever it is called with a standard 110 volt receptacle and plug in my Volt charger into this 110 volt (now 220 volt) receptacle?

Technically yes...but if someone where to accidentally plug a 110/120 device into it it will damage the device and could cause a fire. That is a problem in countries like the Philippines that use the American style Type B plug for both 120v and 240v devices.

Late response and long response here but I feel I should add the fact that.. since you are considering using a 110 outlet for 220... that the internal components of outlets are designed to handle the voltage they are configured for and in the U.S. with many cheaper 110 outlets sold in big box stores there are failures even when transmitting 110 15amp current. These failures and overheating occur with cheap switches also..especially with cheap dimmer switches. I am not a licensed electrician but I was taught in the 1970s by a master electrician and I have worked with residential and commercial wiring for many years doing remodeling. I would recommend at a minimum using a good quality 220 outlet and good quality self wiring plug and socket ends (the ones with ribbed screw down contact plates for the stripped wire ends)(the ones shown in the image do look like they are good quality ) on the pigtail/adapter wire. The "savings" / "simplicity" in using a 110 outlet hardly seems worth it. The point made earlier in this thread by the woman (can't remember her name) about how 110 and 220 are carried on the 110-black hot and white neutral... 220- black hot..red hot..and white neutral leaves open the question of how and or if the neutral 110 leg is switched for 220 within the control (?control?) box that has the green and yellow indicator lights. Apparently it is switched because it is charging for you at 220 without problems but I don't really understand how the neutral flat plug now carries the red 220 hot once it is in the control box since it was the neutral leg in 110. I'm not doubting it's working fine for everyone but it strikes me as an odd/weak transmission point within that control box and also the cord on the charger that came with my 2017 is not short- 22 feet long- and it is stamped as only 3 conductor 16awg. Does anyone reading this have a factory manufactured 220 charger who could post what the gauge and length of the wire is 🤔 ? Hope this post isn't confusing and I don't mean to doubt that the configuration you've made works.

How is the temperature of the cord on the car side, when running at 2880W compared to running at 1440W? What gauge wire does the EVSE have?

It is a little warm from the EVSE to the vehice. Really don't notice it at all in an overcast cloudy day. Gets warmer in the sun. Won't be such a bad thing in the very cold VT winters here. Internal wiring is 16 gauge.

@Bigsnoman

(in agreement) 16 Gauge Wire is rated at 13 amps for each current carrying conductor. It's definitely right there on the edge for the charger cable and a 30 AMP circuit size prefered. Many Level 2 chargers prefer to have 125% power availability for the rating of the charger (24 amps on a 30 amp circuit). This modification accommodates that charger sizing requirement for this 30 amp circuit without paying the hundreds of dollars for a new charger.

I think you also have to change the "8 amp charging" setting to a "12 amp setting" in the system on the display.

@GreenMountainDIYGuy

That setting on the Chevy Volt (8 amp to 12 amp) is used only when using the stock EVSE is in 120 volt mode. When using a 240 volt EVSE, the 8 amp to 12 amp setting has no effect.

Yes, you will charge faster using 12 amp in that mode. If charging at 12 amps (120 volt), you should at least have a 15 amp breaker and receptalce for house wiring. Again, the settings between 8 and 12 amp only works on the 120 volt side. If you are using the EVSE at 240 volts (or any other EVSE at 240) then the 8 and 12 amps settings have no effect.

PERSONALLY, I WOULDN'T DO IT. Your modified "220 receptacle" would look just like any other regular receptacle. Too many possibilities of plugging in a normal 120 device into it and that would certainly spell a disaster. Put a dedicated 220/240 outlet in and make an adapter. That would be the safest approach. Of course, doing any of this is at your own risk...

Melanie, are the thicker gauge wires required by U.S. building codes for 220 volt circuits based simply on the the larger draw usually required for 220 appliances and not just the voltage difference... as you stated it's just two 110 hot feeds but thicker wire is always mandated in the codes.
