What Open EV Charging Networks Are
Open EV charging networks are public charging stations that any electric vehicle owner can use, regardless of which car brand they drive or which charging company operates the station. Unlike proprietary networks tied to a single manufacturer — Tesla's Supercharger network being the most familiar example — open networks accept vehicles from all makers and typically use standardized plugs and payment methods.
The largest open networks in North America include Electrify America, EVgo, and Charge Point. These networks operate thousands of stations across highways, parking lots, shopping centers, and city streets. Some are owned by the charging company itself; others are owned by property managers, municipalities, or utilities that contract with a network operator to handle billing and maintenance.
Open networks matter because they reduce the risk that you'll buy an EV only to find charging infrastructure locked behind a brand you don't own. They also create competition on price and service quality, which tends to push costs down and reliability up over time.
Key Takeaways
- Open EV networks like Electrify America and EVgo let you charge any electric vehicle at their stations, with payment handled through apps, cards, or memberships.
- Charging costs vary by network, location, and whether you pay per kilowatt-hour or per minute; highway fast-chargers typically cost more than slower Level 2 chargers in parking lots.
- Most networks offer both pay-as-you-go and monthly membership plans, and membership often saves money if you charge more than once or twice a week.
- Charging speed depends on the station type: Level 2 chargers add 25–30 miles of range per hour, while DC fast-chargers add 150–200 miles in 20–30 minutes.
- Network coverage varies significantly by region; checking a map before buying an EV helps you understand what charging will actually look like where you live and travel.
How Charging Speed and Station Types Affect Cost
Open networks operate three main types of chargers, and the type determines both how fast you charge and what you pay. Level 2 chargers use standard 240-volt power and add roughly 25 to 30 miles of range per hour. They're common in parking lots, apartment complexes, and shopping centers. DC fast-chargers use high-voltage direct current and add 150 to 200 miles in 20 to 30 minutes; these are what you'll find on highways and at major travel corridors.
Pricing reflects the difference in power delivery. Level 2 charging typically costs between $0.20 and $0.40 per kilowatt-hour, or sometimes a flat fee of $2 to $5 per session. DC fast-charging costs more — usually $0.30 to $0.50 per kilowatt-hour, or $10 to $20 for a 20-minute charge. Some networks charge by the minute instead of by energy used, which can penalize you if the charger is slow or if you're charging a large battery.
The actual cost to add 100 miles of range varies by your vehicle's efficiency and the charger's pricing model. A Tesla Model 3 might cost $8 to $12 for 100 miles at a DC fast-charger, while a less efficient vehicle could cost $15 to $18 for the same distance. Checking the network's app before you plug in shows you the exact rate for that station.
Membership Plans Versus Pay-as-You-Go Pricing
Most open networks offer both a pay-as-you-go option and monthly or annual membership plans. Pay-as-you-go means you pay the full per-kilowatt-hour or per-minute rate each time you charge; no upfront cost, but no discount either. Membership plans typically cost $10 to $25 per month and reduce the per-kilowatt-hour rate by 10 to 30 percent, or waive session fees.
Membership makes financial sense if you charge at open network stations more than once or twice a week. If you charge at home most of the time and use public chargers only for road trips, pay-as-you-go is usually cheaper. Some networks offer tiered memberships — a basic plan for occasional users and a premium plan for frequent travelers — so you can match the plan to your actual charging pattern.
A few networks also offer loyalty programs or time-of-use discounts that lower rates during off-peak hours. Checking your own charging habits — how often you use public chargers, what time of day, and whether you're mostly on highways or in cities — helps you pick the plan that costs least over a year.
Regional Differences in Network Coverage and Pricing
Open network coverage is not uniform across the country. Electrify America and EVgo have the broadest footprint, but density varies sharply. The West Coast, Northeast Corridor, and major metropolitan areas have dense networks; rural areas and parts of the Midwest and South have far fewer stations. Some states have invested in their own charging infrastructure, which may or may not be integrated into the major open networks.
Pricing also varies by region and by individual station. A DC fast-charger in a rural area might charge less than one in a major city, or vice versa — it depends on local electricity costs, competition, and the owner's pricing strategy. Networks publish their rates in their apps, and rates can change; checking the app before you charge is the only way to know the current price at a specific location.
If you're considering buying an EV, mapping out the open network stations along your regular routes and any trips you plan to take gives you a realistic picture of charging costs and convenience. This is especially important if you live in an area with limited home charging options or if you take frequent long drives.
How to Find and Use Open Network Chargers
Most open networks operate their own apps — Electrify America, EVgo, and Charge Point each have one — and these apps show real-time station locations, availability, pricing, and charging speed. You can also use aggregator apps like PlugShare or A Better Route Planner, which combine stations from multiple networks and let you filter by charger type, price, and availability.
To charge at an open network station, you typically create an account in the network's app, add a payment method, and then either scan a QR code at the charger or enter the station ID in the app to start a session. Some networks also accept contactless payment via credit card at the charger itself, though this usually charges the full pay-as-you-go rate without membership discounts.
Most networks require you to stop charging or pay an idle fee if you leave your car plugged in after the charge is complete. Idle fees typically range from $0.50 to $1.00 per minute and are designed to keep chargers available for other drivers. Checking the app to see when your charge will be complete helps you avoid these fees.
Reliability and What Happens When a Charger Is Broken
Open network chargers break down, and availability varies. Networks report uptime rates of 90 to 95 percent, but that means 5 to 10 percent of chargers are down at any given time. The apps show which chargers are currently out of service, so you can plan around them. On long road trips, it's wise to know where the next two or three charging options are, in case your first choice is unavailable.
If a charger fails during your session, most networks will not charge you for the failed attempt. If you're charged and believe it was an error, you can dispute it through the app or by contacting customer support. Response times vary by network; Electrify America and EVgo typically respond within a few business days.
Network reliability has improved significantly over the past two years as companies have invested in maintenance and monitoring. Still, relying on a single charger for a critical trip is risky; having a backup plan is part of road-trip planning with an EV.
How Open Networks Compare to Proprietary and Home Charging
Tesla owners have access to Tesla's Supercharger network, which is proprietary but now opening to non-Tesla vehicles through adapters. Superchargers are generally fast and well-maintained, but they're not available to non-Tesla owners in all regions, and pricing is set by Tesla. Open networks offer broader access but sometimes less consistent quality and availability.
Home charging — whether Level 1 (standard outlet) or Level 2 (240-volt) — is almost always the cheapest option if you have a driveway or garage. Charging at home overnight costs roughly $0.10 to $0.15 per kilowatt-hour in most of the country, compared to $0.30 to $0.50 at public DC fast-chargers. For daily driving, home charging covers most needs; open networks fill the gap for road trips and situations where home charging isn't possible.
The practical strategy for most EV owners is to charge at home as much as possible and use open networks for longer trips or when home charging isn't available. This minimizes public charging costs while keeping you mobile.
Frequently Asked Questions
Can I use an open network charger if I don't have a smartphone?
Most networks require an app or online account to start a session, but some accept contactless credit card payment directly at the charger. Call the network's customer service before your trip to confirm payment options at specific stations. A few networks are adding QR-code-free payment methods, but smartphone access remains the most reliable way to charge.
What happens if I run out of battery between charging stations?
Plan your route using an app like A Better Route Planner, which accounts for your vehicle's efficiency and range. If you do run out of power, roadside information through your car's warranty or an auto club can tow you to the nearest charger. This is rare if you plan ahead, but it's why checking charger locations before long trips matters.
Do I have to join a membership to use open network chargers?
No. You can pay per session without a membership, though the per-kilowatt-hour rate will be higher. Membership is optional and worth it only if you charge at public stations regularly. For occasional road-trip charging, pay-as-you-go is usually cheaper.
Can I charge my EV at a network charger if it's a different brand than my car?
Yes. Open networks accept all EV brands. You may need an adapter for certain plug types — for example, older Teslas use a proprietary connector — but the network itself doesn't restrict you by vehicle brand. Check your car's manual or the network's website to confirm connector compatibility.
How long does it take to charge at a public charger?
Level 2 chargers take 4 to 10 hours to fully charge a typical EV battery. DC fast-chargers take 20 to 40 minutes to add 150 to 200 miles of range. Most road-trip charging uses DC fast-chargers and takes 20 to 30 minutes, which is why they're common on highways.
