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)

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:

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.

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.

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)

The OM p.244-245 describes all the light colors and what they mean, but the flashing red is not discussed, only pulsing red. Seems light an oversight. The flashing red should have been noted with a page link to the security section (which also does not mention the flashing red).

What if I have charging issues? What do the charge cord lights mean?

Here is a Charging Troubleshooting chart (from the car owners manual). Note: These are different than what the Dual Level Charge Cord install sheet says, I'm not sure why.

Verify the charge cord status on the charge cord control box. The charge cord uses a combination of red and green indicators to display the status of the charge cord.

GreenRedReasonAction

The adapters are all designed to easily convey the current flowing through the wires. Grizzl-e has quality products which is why they charge a bit more. If it wasn't safe, then they wouldn't sell it. I have an adapter set up on mine. The connections were all tight and snug but I still wrapped them with gorilla tape to ensure they won't ever come apart.

I respect that you want the safest setup and just wanted to provide another potential option to you. Best of luck with your future setup. 👍

Black box needs to be "warm" to allow just enough epansion to allow pigtail removal. I changed a friends Optic that drew max amps and got quite "warm".

Pigtail was then easy to remove.

Personal choice was to grind smooth the pigtail's stop to facilitate future swaps.

The 2025 RS does not come with a charge cord, just the bag to put one in??? Luckily the 2023 Bolt EUV I traded in had one that I kept. Fits in the bag nicely.
But I mostly charge with my Emporia charger which is the best!
Canadians are forced to buy one with both 2024 and 2025 MY. American's had the option of ordering one with their car in the 2025 MY. Whether being forced to buy something is good or bad, I leave that opinion up to you.

Hello all! Just took delivery on Monday, first EV and i'm loving it. So far I've just been trickle charging with the OEM 120v charge cord. The charge rate is what you'd expect (~3mi range per hour at 12v). However, while charging, I get a myChevrolet (Android) notification every hour or so that Charging has Started... and once it reached 80%, as set, repeated "Charging Complete" notifications. Is this normal, or could it indicate an issue with the outlet, charge cord, or Equinox? I can disable the notifications if it's just the app being weird. Thank you!

Just got me Equinox EV and looking to install a 240 outlet to boost my charging. I believe the included dual levels charger I got ( not one of the more expensive options) is 40 amps max. I want to install a 50amp breaker for a little future-proofing in case I want to upgrade the charger later, but I'm not 100% sure if it's ok to plug a 40amp charging cord into an outlet wired to a 50amp breaker.

I assume it's fine and the charger itself manages the flow of electricity in the same way not all appliances/electronics we plug into a 15amp outlet uses all 15 amps oe the recommended max 12 amps. But I wanted to check with the community to be sure before I move ahead and potentially burn out the charger.

Thanks.

Yes, it is recommended to plug a MAXIMUM 40amp charging cord into an outlet with a 50amp breaker. For continuous electrical loads, like EV charging, the circuit should not be loaded beyond 80% of the breaker's maximum rating, which in this case would be 40amps. The GM-supplied dual level charge cord is actually 32amps maximum on 240V, which is below 80% of the breaker, so it is fine, too.

Glad to hear the plug is OK. If the manufacturer of the plug specifies EV use, one would hope it is OK.

Is the torque of the connections OK as well?

The one below is the one I used. Torqued by electrician. Made sure he did not over do it either as that can lead to problems too.
