What EV charging companies do and how they make money

EV charging companies build and operate the stations where you plug in your electric vehicle, and they charge you for the electricity you use. Some are networks that own stations across multiple states — Tesla Supercharger, Electrify America, EVgo, and Chargepoint are the largest. Others run charging at specific locations: a grocery store chain might contract with a local operator, or a workplace might install its own charger and hire a company to manage it.

These companies make money in three ways: charging fees per kilowatt-hour (kWh), monthly subscription plans, or both. A few offer free charging as a loss leader or as part of a vehicle purchase deal. The pricing model varies widely — some charge $0.25 per kWh, others charge by time plugged in, and some use a flat fee per session. Subscription plans typically cost $10 to $15 per month and give you a lower per-kWh rate or waived connection fees.

The physical infrastructure — the chargers themselves — is often funded by government grants, utility rebates, or the property owner. The charging company operates and maintains it, handles billing, and manages the network app or payment system. This separation between who owns the hardware and who runs it matters when you're troubleshooting a broken charger or disputing a charge.

Key Takeaways

  • EV charging networks operate chargers at different speeds: Level 2 chargers add 25 to 30 miles of range per hour, while DC fast chargers add 200 miles in 20 to 30 minutes.
  • Pricing varies by network and location — some charge per kilowatt-hour, others by time, and subscription plans can lower your per-use cost if you charge frequently.
  • Most networks require an app or membership card to start a session, though some allow pay-as-you-go through a credit card at the charger.
  • Chargers are often owned by property owners or funded by government grants, but operated by the charging company, so you may need to contact different entities if a charger breaks down.
  • Tesla Superchargers were historically closed to Tesla vehicles only, but most networks now allow non-Tesla owners to charge with an adapter or app.

The difference between Level 2 and DC fast charging networks

Level 2 chargers are slower and cheaper to install, so they're common at workplaces, apartment buildings, shopping centers, and public parking lots. They add roughly 25 to 30 miles of range per hour and typically cost $0.20 to $0.35 per kWh. You can leave your car plugged in for several hours without overheating the battery. Companies like Chargepoint and EVgo operate many Level 2 networks, and some utilities run their own.

DC fast chargers are the highway chargers and urban quick-stops. They add 200 miles of range in 20 to 30 minutes, cost more per kWh (often $0.35 to $0.50), and require specialized equipment. Tesla Supercharger, Electrify America, and EVgo focus on DC fast charging. These chargers generate heat and stress on the battery, so most networks limit how long you can stay plugged in and may slow charging speed if your battery is already nearly full.

A charging company might operate both types, or specialize in one. Your choice of network often depends on where you need to charge: if you charge at home or work, Level 2 is sufficient and cheaper. If you take long road trips, you need access to DC fast chargers, which means joining one or more networks that cover your route.

How to find chargers and understand membership or payment options

Most charging networks have a mobile app or website map showing charger locations, real-time availability, and pricing. Plugshare is a third-party app that aggregates chargers from multiple networks in one place, though it doesn't handle payment. Google Maps and Apple Maps now show EV charger locations and some availability data.

Payment methods vary. Some networks require a membership account and credit card on file before you can charge. Others let you pay per session with a credit card at the charger itself, though this usually costs more per kWh than a membership. A few networks offer both options. Subscription plans — typically $10 to $15 per month — lower your per-kWh rate and sometimes waive connection fees, so they pay for themselves if you charge more than once or twice a week.

Tesla Superchargers historically required a Tesla account, but as of 2023, non-Tesla owners can charge at most Superchargers using the Tesla app or a Magic Dock adapter. Electrify America, EVgo, and Chargepoint accept any vehicle with a standard connector and don't require a specific brand membership. If you own a non-Tesla EV, you'll likely need accounts with at least two networks to cover your region and trip patterns.

What happens when a charger is broken or you're charged incorrectly

If a charger isn't working, the app usually shows it as "offline" or "unavailable." Report it through the network's app or website — most have a "report issue" button. The charging company is responsible for maintenance and will dispatch a technician. Response time varies: some networks aim for 24 hours, others take several days. If a charger is broken for weeks, contact the property owner or facility manager directly; they may pressure the operator to fix it faster.

If you're charged incorrectly — double-charged, charged for time you weren't using the charger, or hit with unexpected fees — contact the network's customer service through the app or website. Provide your session ID, the date and time, and a screenshot of the charge. Most networks will review the session data and issue a refund if there's an error. Disputes typically resolve within 5 to 10 business days. If the network refuses to refund you, you can dispute the charge with your credit card company.

Some chargers are owned by the property (a mall, workplace, or apartment building) but operated by the charging company. If you have a recurring problem — a charger that's always broken, or a location that's always overpriced — you can also contact the property manager and ask them to switch operators or negotiate better terms with the current one.

Subscription plans and loyalty programs across major networks

Chargepoint offers a free account with pay-as-you-go pricing, or a Chargepoint+ membership ($9.99 per month) that lowers per-kWh rates and waives connection fees. EVgo has a similar structure: free pay-as-you-go or an EVgo+ membership ($9.99 per month). Electrify America charges per session without a membership, but offers a monthly plan (around $4 per month) that reduces per-kWh rates. Tesla Supercharging is free for some older Tesla models, but most owners pay per kWh without a subscription option.

Loyalty programs are less common than subscription plans. Some networks offer points or credits for frequent charging, but these are usually modest — a few dollars back per month. A few utilities and charging companies offer time-of-use pricing, where you pay less if you charge during off-peak hours (typically late night or early morning). This can save 20 to 30 percent if you can shift your charging schedule.

The math on subscriptions is straightforward: if you charge once or twice a week, a $10 monthly plan usually saves you money. If you charge once a month or less, pay-as-you-go is cheaper. Most people who charge at home (where electricity is cheaper) and only use public chargers for road trips find that a single subscription to one network is enough.

How charging networks handle data and privacy

Charging networks collect location data (where and when you charge), energy use (how much electricity you drew), and payment information. This data helps the company manage the network, bill you accurately, and plan where to build new chargers. Most networks share this data with utilities for grid management and with government agencies for EV adoption tracking.

Your charging history is tied to your account and is not shared with third parties for marketing without your consent. However, the network may use aggregated, anonymized data (total charging sessions in a region, peak charging times) to improve service. Read the privacy policy in the app or on the network's website to see what data they collect and how they use it.

If you're concerned about privacy, you can use pay-as-you-go charging with a credit card at the charger itself, which creates less of a permanent record. However, this usually costs more per kWh and doesn't give you a receipt or session history in an app. Most people accept the data collection as a trade-off for convenience and lower rates.

Frequently Asked Questions

Can I charge my non-Tesla EV at a Tesla Supercharger?

Yes, at most Superchargers. You'll need either a Magic Dock adapter (a physical connector) or the Tesla app on your phone. Some older Superchargers don't support non-Tesla vehicles yet, so check the app before you drive there. Pricing is the same as for Tesla owners.

What's the difference between kWh pricing and time-based pricing?

kWh pricing charges you for the actual electricity you use, so a 30-minute charge costs the same whether you're at a fast charger or a slow one. Time-based pricing charges by the minute, which can be cheaper at slow chargers but expensive at fast chargers. Most networks now use kWh pricing because it's fairer.

Do I have to join a subscription plan to use public chargers?

No. Most networks let you pay per session with a credit card at the charger or through their app. Subscriptions just lower your per-kWh rate if you charge frequently. If you only charge a few times a month, pay-as-you-go is usually cheaper.

What should I do if a charger overcharges me?

Contact the network's customer service through the app or website with your session ID and a screenshot of the charge. They'll review the data and refund you if there's an error, usually within 5 to 10 business days. If they refuse, dispute the charge with your credit card company.

Can I charge my EV at home instead of using public chargers?

Yes, and most EV owners do. Home charging is cheaper per kWh than public charging and more convenient. You'll need to install a Level 2 charger at your home, which costs $500 to $2,000 installed. Many utilities and government programs offer rebates for home charger installation.
