What SemaConnect does and who operates it

SemaConnect is a network of public electric vehicle charging stations owned and operated by Sema Mobility, a private charging infrastructure company. The network includes both Level 2 chargers (which add 10 to 30 miles of range per hour) and DC fast chargers (which add 100 to 200 miles in 20 to 40 minutes, depending on the vehicle and charger model). Stations are located across multiple states, with concentrations in the West and Midwest, though the network continues to expand.

SemaConnect stations are typically found at workplaces, retail locations, parking garages, and municipal lots. Unlike some charging networks that require membership through a specific utility or automaker, SemaConnect stations can be accessed by most EV owners through a pay-as-you-go model or through a membership account. The company operates its own mobile app and website for locating stations and managing charging sessions.

Key Takeaways

  • SemaConnect stations include both Level 2 and DC fast chargers at various public locations, and you can start a session using the SemaConnect app, a physical card, or a contactless payment method.
  • Pricing varies by location and charger type; some stations charge by the hour, others by kilowatt-hour, and rates are displayed in the app before you plug in.
  • You can use SemaConnect without a membership account by paying per session, or you can create an account to track usage and set up payment methods in advance.
  • SemaConnect stations are compatible with most EVs that have a standard SAE J1772 connector (Level 2) or CCS/CHAdeMO connector (DC fast charging), though you should verify your vehicle's connector type before relying on a specific charger.
  • If a charger is broken or unavailable, the SemaConnect app shows real-time status, and you can report issues directly through the app to help other drivers.

How to locate and access a SemaConnect station

The SemaConnect mobile app and website (semaconnect.com) let you search for stations by address, zip code, or map view. The app shows the charger type (Level 2 or DC fast), connector types available, real-time availability, and current pricing. You can filter results by charger speed, network, or distance from your location.

To start charging, you have three options: use the SemaConnect app to unlock and start a session, use a physical SemaConnect card if you have one, or use a contactless payment method (Apple Pay, Google Pay, or credit card) at chargers that support it. The app will guide you through each step and send you a notification when charging is complete or if there is an issue.

Before you arrive at a station, check the app to confirm it is available and note the connector type your vehicle uses. Most Level 2 chargers use the SAE J1772 standard connector, while DC fast chargers may use CCS (Combined Charging System) or CHAdeMO connectors depending on the station. Your vehicle's manual or the manufacturer's website will tell you which connector your EV has.

Pricing and payment methods

SemaConnect pricing is set by the station owner or operator, not by Sema Mobility, so rates vary widely. Some stations charge by the hour (typically $1 to $3 per hour for Level 2), others charge by kilowatt-hour (typically $0.20 to $0.40 per kWh), and DC fast chargers are usually more expensive per minute. The app displays the exact rate before you start a session, so you know the cost upfront.

You can pay per session using a credit card, debit card, Apple Pay, or Google Pay at the charger itself or through the app. If you charge frequently at SemaConnect stations, creating an account lets you save payment methods, view your charging history, and receive receipts by email. Some employers or organizations that host SemaConnect chargers may offer discounted or free charging to members, so check with your workplace or local facility.

Membership and account options

SemaConnect does not require a membership to charge. You can pay per session without creating an account, though you will need a way to start the charger (app, card, or contactless payment). Creating a free SemaConnect account takes a few minutes and requires an email address and password. An account lets you save multiple payment methods, set up automatic billing, and track your charging sessions over time.

Some charging networks offer monthly or annual subscription plans that reduce per-session costs if you charge frequently. SemaConnect's pricing structure varies by location, so check the app or contact SemaConnect directly to see if a subscription plan is available at the stations you use most often.

Connector types and vehicle compatibility

Most SemaConnect Level 2 chargers use the SAE J1772 connector, which is the standard for Level 2 charging in North America. Nearly all EVs sold in the United States have a J1772 port, so Level 2 compatibility is rarely an issue.

DC fast chargers on the SemaConnect network use either CCS (Combined Charging System) or CHAdeMO connectors. CCS is used by most newer EVs from Tesla (with an adapter), Ford, General Motors, Volkswagen, BMW, and others. CHAdeMO is used by some Nissan Leaf models and a few other vehicles. Tesla vehicles can use CCS chargers with a Magic Dock adapter at some SemaConnect locations, but not all stations have this feature yet.

Before relying on a specific SemaConnect station, check your vehicle's manual or the manufacturer's website to confirm which connector type your EV uses. The SemaConnect app also filters stations by connector type, so you can search only for chargers compatible with your vehicle.

What to do if a charger is broken or not working

The SemaConnect app shows real-time status for each charger, including whether it is available, in use, or out of service. If you arrive at a station and the charger is not working, the app should reflect that status. If a charger appears available in the app but does not work when you arrive, you can report the issue directly through the app, which notifies SemaConnect and the station operator.

If you have already started a charging session and the charger stops working, contact SemaConnect support through the app or website. You should not be charged for a session that was interrupted due to equipment failure, though the process for getting a refund or credit varies by location and payment method. Keep your receipt or session confirmation in case you need to dispute a charge.

Comparing SemaConnect to other charging networks

SemaConnect is one of several public charging networks in the United States. Other major networks include Electrify America, EVgo, ChargePoint, and Tesla Supercharger (for Tesla vehicles and some non-Tesla EVs with adapters). Each network has different coverage areas, pricing models, and connector types, so the best choice depends on where you charge most often.

If you charge at home or at work regularly, you may not need to use public networks often. If you rely on public charging, using the SemaConnect app alongside apps from other networks lets you compare prices and availability in real time. Some EVs come with subscriptions or discounts to specific networks through the manufacturer, so check your vehicle's documentation to see if you have any built-in benefits.

Frequently Asked Questions

Do I need to create a SemaConnect account to charge?

No. You can pay per session using a credit card, debit card, or contactless payment method at the charger without an account. Creating an account is optional and is useful mainly if you charge frequently and want to track your history or save payment methods.

What if my EV has a different connector type than the SemaConnect charger?

You will not be able to use that charger without an adapter. Check the SemaConnect app to filter stations by your vehicle's connector type before you go. If you have a Tesla, some SemaConnect DC fast chargers have a Magic Dock adapter, but not all do, so verify in the app first.

How long does it take to charge at a SemaConnect station?

Level 2 chargers typically add 10 to 30 miles of range per hour, so a full charge takes 4 to 10 hours depending on your vehicle's battery size. DC fast chargers add 100 to 200 miles in 20 to 40 minutes. The exact time depends on your vehicle, the charger's power output, and your battery's current charge level.

Can I reserve a SemaConnect charger in advance?

SemaConnect does not offer advance reservations through the app. You can see real-time availability and locate nearby stations, but you cannot hold a charger. If you need may provide charging access, check whether your workplace or regular location has a dedicated charger you can use.

What happens if I leave my car plugged in after charging is complete?

Most SemaConnect chargers stop charging once your battery reaches full or the session time expires. Some stations may charge an idle fee if your vehicle remains plugged in after charging ends, though this varies by location. Check the app or station signage for idle fee information before you leave your vehicle.
