What GM Charging Stations Are and Who Can Use Them
General Motors operates two main charging networks: GM Energy, which includes home and workplace chargers that GM sells directly, and Ultium Charge 360, which is GM's roaming network that gives GM EV owners access to third-party charging stations across North America. If you own a GM electric vehicle — a Chevrolet Bolt, Cadillac Lyriq, GMC Sierra EV, or other GM EV — you can use both networks, though the terms and costs differ between them.
GM Energy chargers are hardware you purchase and install at your home or business. Ultium Charge 360 is a membership or pay-as-you-go service that connects your GM vehicle to networks run by companies like Electrify America, EVgo, ChargePoint, and others. You do not need to be a GM customer to use some third-party stations, but GM owners get priority access and often lower rates through the Ultium partnership.
Key Takeaways
- GM Energy sells home and workplace chargers directly; Ultium Charge 360 is a roaming membership that connects you to third-party networks.
- GM EV owners can access over 500,000 public and workplace charging ports through Ultium Charge 360 across the US and Canada.
- Pricing varies: home chargers range from a few hundred to several thousand dollars depending on power level; public charging is billed per kilowatt-hour or per minute.
- Your GM vehicle's infotainment system shows available stations nearby and can reserve or start a charge remotely through the GM Energy app.
- Installation of a home charger typically requires an electrician and may may have access to for federal tax credits or state rebates depending on your location.
GM Energy Home and Workplace Chargers
GM Energy offers two types of home chargers: the GM Energy Dual Port Home Charger and the GM Energy Home Charger. The dual-port model can charge two vehicles at once and costs between $700 and $900 before installation. The single-port charger is less expensive. Both are Level 2 chargers, meaning they deliver 240 volts and add roughly 25 to 30 miles of range per hour of charging, depending on your vehicle and the charger's power output.
Installation requires a licensed electrician and typically costs $500 to $2,500 depending on how far your electrical panel is from the installation location and whether your home's electrical service needs an upgrade. Some homes with older service panels may need a 200-amp upgrade, which adds significant cost. GM offers financing options through its website, and you may be able to claim a federal tax credit of up to $500 for the charger hardware itself under current tax law, though rules and amounts vary by year.
For workplaces, GM Energy also sells commercial chargers and can help businesses set up charging infrastructure. Pricing and installation for commercial units depends on the site and power requirements, and you would need to contact GM directly for a quote.
Ultium Charge 360 and Public Charging Access
Ultium Charge 360 is GM's roaming network membership. When you buy a new GM EV, you typically receive a complimentary trial period — often 24 months of free charging at most Ultium-connected stations. After that period ends, you can continue using the network on a paid membership basis or pay per charge.
The network includes over 500,000 ports across the US and Canada, operated by partners like Electrify America (which has the most DC fast-charging stations), EVgo, ChargePoint, and others. You access these stations through the GM Energy app or your vehicle's infotainment system. The app shows real-time availability, lets you reserve a charger, and can start and stop charging remotely.
Pricing for public charging after your trial period varies by network and charger type. DC fast chargers typically cost $0.25 to $0.50 per kilowatt-hour or $10 to $15 per 30-minute session. Level 2 chargers at workplaces or retail locations often cost $0.15 to $0.30 per kilowatt-hour. Some networks charge by the minute instead of by energy used, which can be more expensive if you charge slowly. Membership plans may offer discounts compared to pay-as-you-go rates.
Finding and Using a GM Charging Station
To locate a charger, open the GM Energy app on your smartphone or use the charging map built into your vehicle's infotainment system. Both show nearby stations, their availability in real time, the network operator, and the charger type (Level 2 or DC fast charging). You can filter by charger speed, network, or distance.
To charge at a public station, pull up to an available charger, unlock the port using your vehicle's touchscreen or the GM Energy app, and plug in. The charger will begin communicating with your vehicle and your account. You do not need a separate card or key fob — your vehicle and app handle authentication. Charging time depends on the charger type: a DC fast charger can add 200 miles in 30 minutes on many GM EVs, while a Level 2 charger takes several hours for a full charge.
If a charger is broken or unavailable, the app will show it as offline. You can report issues directly through the app, and the network operator is notified. Response times vary by operator, but major networks typically repair or remove broken chargers within days.
Costs and Membership Options
The total cost of EV charging depends on where and how often you charge. Home charging is the cheapest option: a full charge at home costs roughly $3 to $8 depending on your local electricity rate and your vehicle's battery size. If you charge at home most nights, your public charging costs will be minimal.
Public charging costs more per mile but is necessary for long trips. A 200-mile DC fast-charge session might cost $20 to $40 depending on the network and your membership status. Level 2 public chargers cost less per kilowatt-hour but take longer, so the total session cost is often $5 to $15.
After your trial period ends, you have three options: pay per charge using a credit card linked to the GM Energy app, purchase a monthly or annual membership plan (which typically offer 10 to 20 percent discounts), or use a third-party charging network directly if you prefer. Some networks like Electrify America and EVgo offer their own memberships that may be cheaper if you use them frequently.
Federal and State Incentives for Home Chargers
The federal government offers a tax credit of up to $500 for the cost of a Level 2 home charger and its installation, though the credit applies only to chargers installed in 2023 and later tax years. The credit is non-refundable, meaning it reduces your tax liability but does not result in a refund if your liability is lower than the credit amount.
Many states and utilities offer additional rebates. California, New York, Colorado, and several others have programs that cover 50 to 100 percent of installation costs for low-income households or offer flat rebates of $500 to $2,000 for any household. Some utilities offer time-of-use rates that charge less for electricity during off-peak hours, which can reduce your charging costs significantly if you charge at night.
To find state and local incentives, visit the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local utility directly. Incentive programs change frequently, so checking current offerings before you purchase is important.
Troubleshooting Common Charging Issues
If your vehicle will not connect to a charger, first check that the charger shows as available in the GM Energy app and that you are using the correct port type for your vehicle. Most GM EVs use the North American Charging Standard (NACS), but some older models may use a different connector. If the charger is a different type, you may need an adapter, which GM can provide.
If the app shows a charger as available but it will not start charging, the charger may have a software issue or your account may have a payment problem. Try unplugging and plugging back in, or restart the charger using its physical button. If the problem persists, contact the network operator through the app — most have live support available 24/7.
If you are charged unexpectedly or see a billing error, contact GM Energy support through the app or website. Billing disputes are usually resolved within a few business days, and the company will credit your account if an error is confirmed.
Frequently Asked Questions
Can I use a GM charging station if I don't own a GM vehicle?
Most Ultium Charge 360 partner networks allow non-GM drivers to charge, but you would pay higher rates and would not have access to GM's discounted membership pricing. You would use the individual network's app instead of the GM Energy app. Home chargers are sold only to customers who own or are installing them at their property.
What happens when my free trial charging period ends?
You can continue using Ultium Charge 360 on a paid basis — either pay-as-you-go or through a membership plan. You can also switch to a different charging network entirely. If you do nothing, your account will remain active but you will be charged for each charge at standard rates.
Do I need to install a home charger if I have access to public charging?
A home charger is not required, but it is the cheapest and most convenient way to charge if you have a driveway or garage. Public charging is more expensive and slower, so most EV owners use it only for long trips. If you have a short commute and access to workplace charging, you may not need a home charger.
How long does it take to install a home charger?
The actual installation usually takes one to two days once an electrician is scheduled. However, scheduling can take weeks depending on local demand. If your home needs an electrical panel upgrade, the total timeline can stretch to several weeks. Plan ahead if you want charging ready before a long trip.
Can I charge my GM EV at non-GM charging networks?
Yes. Your vehicle can charge at any public network that uses the NACS connector standard, which includes Electrify America, EVgo, ChargePoint, and others. You would use their apps or cards to pay instead of the GM Energy app, and you would not receive GM's member discounts. Most GM EVs come with NACS as standard.
