The 2024 Equinox EV comes with a charge cord (called an EVSE) supporting both Level 1 (120V) AC up to 1.4 kW via a 15A breaker and Level 2 (240V) AC charging at up to 7.7 kW (about 23 miles/hour) via a 40A breaker.

The Equinox EV supports a higher charging of 11.7 kW (about 34 miles/hour) (on a 60A circuit with a 48A capable EVSE) but this Dual Level Charge Cord does not support that. This Dual Level Charge Cord can be used indoors or outdoors and has a 3 year limited warranty.

Two Versions
There are TWO VERSIONs of this charge cord, the earlier one is white, the current version is black. Besides color, they are constructed differently. The white version has a row of 4 plugs on the cord that snap into the control box. The black version has the 4 plugs arranged in a square, two rows of two.

Please note: All charging requires a dedicated circuit suitable for the heavy-duty, continuous load of charging. In other words, don't plug into a circuit that's also used by other appliances (refrigerator, freezer, garage door opener, table saw, dehumidifier, toaster, stoves, etc.). You could overload the circuit and trip the breaker, or smoke/melt/char the wiring or worst case cause a wiring fire.

120V Or 240V?
Depending on your home's outlet, you plug either the 120V pigtail into the unit or the 240V pigtail.

Zippered Bag
The Equinox EV charge cord also comes with a zippered cloth case that fits under the cargo deck on the rear passenger side

Here's the first gen version (white, a linear plug into the control unit)

Image


Here's the 2nd gen version (black, a rectangular plug into the control unit):

Are there instructions on how to use the dual level charge cord? Yes, they will come with the cord but here they are as well:

Image


Attached at the bottom of this post is a PDF of the GM Dual Level Charge Cord instructions and installation, or here's a webpage

How Long is the Charge Handle Cord?
It's 25 feet long from the control box to the end of the handle.

Is there a GFCI (Ground Fault Circuit Interrupt) built in?
Yes, according to the Status Indicator Lights Key chart below.

What Do I Need to Use this at 120V?
A standard wall outlet. If the outlet is old or worn, replacing it with a new receptacle is a good idea. The contact blades inside a receptical can get lose/sloppy over the years potentially causing electrical arcing or even plug melting. If replacing the outlet, go with a hospital or commercial grade unit rather than a 99 cent special. Wire to the terminal screws, don't use the back-stab option.
Image



What Do I Need to Use this at 240V?
Note that the 32A level 2 option requires
  1. a dedicated circuit with a 40A breaker. and
  2. a NEMA 14-50R receptacle. The Hubble version is beefier for high, continuous load (and more $) than the Leviton version. I think beefier is better when it comes to safety, even has a little green plugin car... Still in doubt? One Equinox EV owner's experience: "My professionally installed receptacle melted on one side, causing a lot of havoc --fried grizzlE cord at receptacle, a disgusting smell in garage, late to a key work event, etc. So it's true that paying a lot of money for the top electrician to install the receptacle and cord, breaker, line etc. means nothing. Next time I'll buy the industrial socket and make them use it." Also insist they use a torque screwdriver on the screws holding the power wires. "Hand tight is good enough" isn't.

This 4-prong outlet gets installed in an over-sized RACO 888 Raised Square Exposed Work Cover, 2-5/8 in Dia L X 4-11/16 in W X 1/2 in T, 4-11/16" cover plate mounted to an over-sized Hubbell-Raco 8257 2-1/8-Inch Deep, 1/2-Inch and 3/4-Inch Side Knockouts Welded 4-11/16-Inch Square Box. These are bigger to accommodate the thicker wires that will be used from the circuit breaker. The box has knockouts for 3/4" conduit (again, thicker wires). The outlet, cover plate and box are available on Amazon and at big box stores.

Image




The charge cord plugged into this will support 7.7 kW charging. Again, the 2024 Equinox EV can handle 11.7 kW but you'd need a 50A circuit for that and you'd need to buy a different charge cord that supports 48A (a 50A breaker), 240V 11.7kW charging. GM, ChargePoint, Siemens and other will gladly sell you a unit in the $550 range.

Can I plug into my electric clothes dryer outlet instead? Probably. If you have the white charge cord unit, an optional kit (GM Part # 84877187) with other plugs is available for plugging in to NEMA 5-15, NEMA TT-30, AND NEMA 14-30 outlets. These and other related parts are available at AC Delco directly or through GM parts sellers. No such kit exists for the black Ultium charge cord.

Is there a video I can watch?
Yes, here's a Chevy Support webpage and video on the charge cord with explanation and details (the Bolt EV is still mentioned)

Hello! I'm the proud owner of a new 2025 Equinox EV, however the one I bought came with a gen 2 charging cable which I don't need. They said since it was on the window sticker they wouldn't take it off. They didn't charge me freight costs so I figured I wouldn't fight them on it - I'm a previous bolt owner and already have one. Is this the place to offer to sell it to somebody? If anybody is interested, let me know! I can provide pictures, verification, or anything requested.

Sorry to resurrect this ancient thread. I just got my personalized plates so it was the perfect time to check if I could stick my charger bag in the storage area like mentioned earlier.

We have two examples:
Image

@M L

Image

@Jim99

If you look at Jim's, in the front right corner, it clearly is not fitting well. MLs appears to sit in there just fine

Jim, does your floor sit flat with that bagged crammed in there like that? ML did you raise that leg? Did it change the fit at all? You said it was crammed in, but is it squished in there like Jim's?

Separately, my foot was in a half raised position and when I raised it, it took some bow out of the floor. I am wondering if this was something I knocked earlier or if it came that way, maybe it should be in the delivery inspection tips.

I didn't put my bag in that position because it just didn't fit right yet. Now, as I sit here, I'm wondering if there is a stiffener in the bag that could be trimmed just a bit. Or maybe I just need to put on my big boy pants and just stuff it in there.
 
#128 ·
ML did you raise that leg? Did it change the fit at all? You said it was crammed in, but is it squished in there like Jim's?
Yes, I did raise the leg after that picture was taken. It didn't affect the fit of the bag. The bag is a little "squished" in the corners, but not significantly. I like having the EVSE in the car as a backup, but I doubt I'll use it very often.

Dryer outlet: NO,NO, NO. They are cheap ($10) outlets designed for low load appliances. They are not capable of handling the sustained loads of EV charging.

An EVSE requires an industrial (~$50) NEMA 14-50 or hard wire install ONLY. The (4") face plate for the industrial 14-50 has a larger diameter cut out which is a bit of a challenge to find, but no need to give organized crime (amazon) money <bad link removed>, etc.).

The original (Volt; Bolt) L1 supply cord was and is good quality. The "1st" generation combination supply cable referred to above was junk and was easily broken. "2nd" generation (above) seems to be back to original good quality, but I have not tried it out yet. And it is sold via dealer (ADM), not now included in purchase price.

Always purchase a "dumb" charger and never get roped into any utility company scam.
All EVSEs contain Clipper Creek (now owned by Enphase) technology. Never purchase a "cheap" EVSE.
I have owned Clipper Creek EVSE for 7+ years, never a problem.

Best advice is DO NOT CUT CORNERS with electrical. (sure you can purchase tools from Sears (and they might replace them when they break) if you do not use them.......

Do not know why LightbulbWholesaler(above) was removed by admin./"moderator" but it is where I purchased my face plate so try again:

I guess I am not seeing the answer or dont know what I am looking for directly.
We have had a model 3 for 5 years and have always user the NEMA 10-50P outlet with an adaptor from AC works.
On the website its says its made for the use with tesla and they would not confirm it could be used for the Chevy.
Image


Is this ok to use or would I need the one with the ground wire.

What this not just for the house that will be temp as are putting in a level 2 having 2 EVS.
But for on the road as well as a just in case.

Thanks for the help- tell me if I should post this elsewhere.

Keep in mind, it's three different cords, one a duplicate of what came with the Ultium charge cord, and these only work with the white Ultium charge cord, not the later black version.

Finderomend 4 Prong Dryer Y Splitter Cord
Yes, like many it looks promising at first glance, but:
  • They show the ends in the rain, lol. No protection from death by electrocution that I can see. Extremely lethal for outdoor use as shown.
  • No lookout protection to prevent causing a fire by using both the dryer and the car EVSE at the same time. This can easily cause an accident (smoke, melting plastic, fire).
  • And this "Remember to adjust your charging rate to prevent overheating or circuit breaker triggering" which the Ultium EVSE can't do.
I would strongly recommend against this type of solution. The proper and safe way for something like the dryer illustration they show is to install a second 2-gang electrical box for the car with the 240V receptacle controlled by a 240V DPDT switch that either powers the dryer OR the EVSE, but NEVER allows both at the same time.

For outside campground use, you need a waterproof (think marine use like a boat dock) connection between the EVSE plug and the adapter. Again 240V is lethal.

Continuing the topic of water and 240V ... I'm reading this charger is IP66. Does it make it safe to store outside, while plugged into a weatherproof outlet? How about being in use/charging while raining?

The point of the short outlet adaptor connection to the charger gives me pause, but perhaps I'm overthinking this.

The IP rating normally has two (but may have three) numbers:
  1. Protection from solid objects or materials
  2. Protection from liquids (water)
  3. Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529)
Solids ingress protection Levels 5 and 6 are concerned with dust protection. Level 5 allows some dust to enter, but not enough to affect equipment operation. Level 6 is fully dust-tight. IP water resistance varies from mild drip resistance, through sprays, jets, and total immersion. For Levels 5 and 6, hose nozzles are used. The Level 5 exposure is at 12.5 liters/minute through a 6.3 mm (1/4 inch) nozzle. Level 6 is a higher pressure and flow test, using a 12.5 mm (1/2 inch) nozzle at a flow rate of 100 liters/minute. For both Levels 5 and 6, the hosing is conducted from a distance of 2.5 to 3 meters. Exposure time is three minutes. Level 7 would be putting the unit in a dunk tank.

My Ultium EVSE says "Enclosure Type 4X" not IP66 but I think they are very similar aag.

NEMA 4 and 4X
Watertight. Must exclude at least 65 GPM of water from a 1-inch nozzle delivered from a distance not less than 10 feet for 5 min. Used outdoors on ship docks, in dairies, in wastewater treatment plants and breweries. X (as 4X) indicates additional corrosion resistance.

So yes, safe to charge during rain, safe to use outdoors PROVIDED the cord is firmly seated into the control unit, the plug and the receptacle are in a weather proofing enclosure (usually a clear plastic bubble surrounding them both with the cord coming out the bottom. Here's an example

The 2024 Equinox EV comes with a charge cord supporting both Level 1 (120V) A up to 1.4 kW and Level 2 (240V) charging at up to 7.7 kW (about 23 miles/hour). The Equinox EV supports a higher charging of 11.7 kW (about 34 miles/hour) (on a 60A circuit with a 48A capable EVSE) but this unit does not support that. This Dual Level Charge Cord can be used indoors or outdoors and has a 3 year limited warranty.

Two Versions
There are TWO VERSIONs of this charge cord, the earlier one is white, the current version is black. Besides color, they are constructed differently. The white version has a row of 4 plugs on the cord that snap into the control box. The black version has the 4 plugs arranged in a square, two rows of two.

In other words, don't plug into a circuit that's also used by other appliances (refrigerator, freezer, garage door opener, table saw, dehumidifier, toaster, stoves, etc.). You could overload the circuit and trip the breaker, or smoke/melt/char the wiring or worst case cause a wiring fire.

120V Or 240V?
Depending on your home's outlet, you plug either the 120V pigtail into the unit or the 240V pigtail.

Is there a GFCI (Ground Fault Circuit Interrupt) built in?
Yes, according to the Status Indicator Lights Key chart below.

What Do I Need to Use this at 120V?
A standard wall outlet. If the outlet is old or worn, replacing it with a new receptacle is a good idea. The contact blades inside a receptical can get lose/sloppy over the years potentially causing electrical arcing or even plug melting. If replacing the outlet, go with a hospital or commercial grade unit rather than a 99 cent special. Wire to the terminal screws, don't use the back-stab option.

What Do I Need to Use this at 240V?
Note that the 32A level 2 option requires
  1. a dedicated circuit with a 40A breaker. and
  2. a NEMA 14-50P (plug) receptacle. The Hubble version is beefier for high, continuous load (and more $) than the Leviton version. I think beefier is better when it comes to safety, even has a little green plugin car...

The charge cord plugged into this will support 7.7 kW charging. Again, the 2024 Equinox EV can handle 11.7 kW but you'd need a 50A circuit for that and you'd need to buy a different charge cord that supports 48A (a 50A breaker), 240V 11.7kW charging. GM, ChargePoint, Siemens and other will gladly sell you a unit in the $550 range.

Can I plug into my electric clothes dryer outlet instead? Probably. An optional kit (GM Part # 84877187) with other plugs is available for plugging in to NEMA 5-15, NEMA TT-30, AND NEMA 14-30 outlets. These and other related parts are available at AC Delco directly or through GM parts sellers

Charging Outlet Installation And Safety
So, I’m having an odd issue.
Have had my 25 LT two weeks tomorrow.
It came with the black EVSE dual level.
I’ve successfully charged it L1 several times via an outside outlet on the garage that we’ve used for an electric grill for years.
Today, with the assistance of a friend, we relocated a 240 receptacle from inside my shop (inside the garage) to an outside heavy duty RV receptacle.
He’s not a master electrician, but he knows what he’s doing.
We checked our results with a meter, and all was well.
At the time, the wife was at work and had the EEV, so couldn’t really test everything.
She got home, and I went out to plug in the newly done L2.
The device flashed both red and green,then settled into a solid red.
Connected to the car, solid red there as well.
Unplugged everything, went into the shop (heated), swapped out the pigtail back to the L1, plugged it into the ac, did the same thing, a couple of both flashing, then went to red.
I took it outside to the outlet that’s previously worked fine, and it behaved normally, going to solid green, plugged it into the car, and it’s charging normally now.
Why would it work fine in one place, but not in two other places…?
It’s all from the same place, and my garage has its own service and panel,breakers, etc.
I guess it’s time to hire a professional sparky…🥴

According to the chart in post #1:

OnThere is a cordset internal fault.Immediately disconnect from the electrical outlet and the vehicle. Contact your dealer for a replacement.

You don't say what the Amperage of the breaker is for the 240V circuit, Shtew. It should be 40A.
We don't know how the receptical was wired but are assuming it follows post#1 as well?

The unit is designed to work at 32A with a 40A breaker (240V breakers are double-joined because there are two hot wires being used instead of one). Did the 30A blow? If not, it certainly could at some point as the unit can draw more current than the 30A breaker is rated for.

Regarding some 120V receptacles working and others not: bad ground, loose or reversed wiring. Depending what you plug in, the appliance may not notice or care. For example, and old light bulb will run without a ground and with the polarity switched. The EVSE does care as there's a GFCI built in as a safety device. Obviously something is different between them. A $8 outlet tester would identify a bad ground or reversed wiring. You don't need to be an electrician to use one. Just plug it in and the light will tell you the story.

I just ordered a 240 RV circuit tester.
Hopefully it’ll tell me what’s wrong.
Will be cheaper than hiring a Sparky for now anyway.
My 240 has a 30A breaker on each 120 leg.
Meanwhile…I continue to charge via the L1…soooooo slowly…
At least I know that I didn’t fry the EVSE…😎

Most residential electricians (including the good ones) are not familiar with EVSEs. They are accustomed to installing cheap NEMAs(14-50) for dryers, etc.
AS RECOMMENDED, ONLY industrial NEMA 14-50(`$50) or hardwired. Properly installed (75 torque) 14-50 only (again most residential electricians will balk at this BUT INSIST- purchase a torque screwdriver if they argue)

Jerryrig/cheap does not work here. Way too dangerous (not to mention your insurance, should they find out , and they will if you file a claim......)
do it right or not at all -or just use L1
Steve's advice is sound and he is simply trying to convince you to be safe and sound.

I bought a 2025 LT at the end of November, it didn't include the cord. I figured I could just order one from GM. Big mistake.
1) The parts website is poorly designed. You can't exclude dealers that don't have the item in stock. You have to manually click on each dealer and see if they have it in stock. At least 50 of the nearest dealers to me don't have the item in stock.
2) I called a local dealer and the parts person said the item is on back order. No idea when it will become available. No way to put my name on a list (that is probably dealer specific, but probably typical).
3) Called the Chevy EV concierge. Same information. On back order, no one can tell when it will be available. No way to contact anyone with responsibility to get updates. And they had been looking into it as other callers had same issue. Half-seriously I told them go to Outlook, click on Mary Barra, then organization, chain down until you find someone who looks like it is their responsibility and send. They did not acknowledge attempting this.
I am disappointed that GM couldn't figure it out any better than this.

Just buy another one than the GM one. You'll get the right one for your wiring available and it'll be fine. And you'll probably save a few bucks in the process.

(GM wants to sell you the big home power package. Which is BETTER, but not everybody needs it or wants to spend that level of money on backup power.)

ChargePoint, Grizzl-e seem well regarded. My Siemens is doing fine. Get one with an adjustable amp setting capability so you can adjust to your circuit capability. Some like wifi app capability, some don't. Some like the ability to schedule charging on the EVSE rather than using the car's scheduler.

The second generation version of the Ultium Dual level charger came with my Equinox EV, with NEMA 14-50 240V level 2 pigtail and 120V level 1 (15Amp plug) pigtail. Since I also wanted NEMA TT-30 charging capability I ordered a NEMA TT-30 pigtail for it from Scroggin Dickey Parts Center, but they sent me the pigtail version for model 1, with the pins in a row of 4 rather than in 2 rows of 2. They dont have version 2 pigtails. With this change in generations, the suppliers are confused as well. Where can I get TT-30 pigtails for version 2? Alternately can I just use a TT-30 to 14-50 adaptor and hope I can set the power down to 24 amps before it starts charging? With the later adaptor, Will the charger recognize the 120 volts and only allow 24 amps? Thank you

Where can I get TT-30 pigtails for version 2?
None for sale or even listed that I know of DancenCamp. The only control you have in the car is choosing between 8A or 12A for 120V. No amp user setting for 240V in the car or the EVSE that. What we don't know is if the TT-30 for V1 has a 24A limiter built in, or if something inside the EVSE control box auto-limits the amps to 24 when it doesn't sense the 14-50P neutral. Something like, "No Neutral detected at 240V? Limit to 24A".

Without a limiter, I expect the EVSE to draw as many amps as the circuit can feed it until the unit gets smoked. You would not want to plug the 14-50P into an 80A 249V circuit for example. 40A is the spec.

3 quick things:
1. My professionally installed receptacle melted on one side, causing a lot of havoc --fried grizzlE cord at receptacle, a disgusting smell in garage, late to a key work event, etc. So it's true that paying a lot of money for the top electrician to install the receptacle and cord, breaker, line etc. means nothing. Next time I'll buy the industrial socket and make them use it.
2. When it was all replaced and I plugged in the EVSE that came with the equinox, the electrician said it was pulling 38amps on one side and 37 on the other. It's rated for 32. What gives?

Sounds like your electrician may have used a cheap outlet. Watch the following
Cheap receptacle and/or terminals not tightened to spec. Either one can cause this. If both are in play, even worse.

The torque spec for terminals is like the torque spec for wheel lug nuts, "feels tight" is not good enough and not professional. Without proper lug nut torque the wheel can come off at high speed because the lug nuts are either too loose or they shear off because they are too tight. Without proper terminal screw torque on a power receptacle, well, melting, smoke, even fire. This is true for standard wall outlets , light switches, and even more critical for outlets carrying high loads.

semi off topic, my 2024 Equinox came with this Ultium portable charger. I had it connected to a dedicated level 2 outlet (nema) and the charger died. Chevy agreed to provide a warranty, but its been a month and the rep tells me there is "no visibility into the delivery date" as its on back order. I asked for a loaner charger; not possible. I asked for an upgraded available charger (and I would pay the diff); not possible.

I don't see anywhere online that GM still makes this charger? Has anyone recently received one or is GM sending out their new charger? Pretty frustrating as the vehicle is sitting in my driveway with 1% on the battery.

The original GM BLACK L1 supply cables (Volt, 2019 Bolt) were/are(still have/use two of them - seven years now) excellent quality. I purchased a second one when I bought the Bolt in 2018. It was of course way overpriced by the dealership. Twice as much+ as its comparative value then and the dealership price for one now.
GM started supplying a white dual cable around 2022? or so which is a piece of junk. I rented a Bolt and it had the white one which was not functional. It was easy to see the poor quality. No sense in it as an option or offer or purchase. I am uncertain why it ever existed.
My advice is if it is white take flight.
My MME had a Ford supplied dual supply cord which was also junk (as were their original "Ford" labeled and sold L2s).
My 2025 Equinox EV has the BLACK dual supply cable which appears to be durable as the originals are, but I have not used it yet. My Clipper Creek EVSE and the two GM BLACK L1s take a licking and keep on ticking and last and last and last as the sayings go.
We pay for quality and the money spent here(L1, L2 & industrial 14-50)) is definitely worth it. Ill advised to cut corners with this much electron flow.
It should be noted that all EVSEs have Clipper Creek(now Enphase) technology in them but they are not assembled equally.
Have fun driving in your car
