EV Charging Tips & Etiquette: What STL Drivers Need to Know

If you’re new to electric vehicles, understanding EV charging etiquette is just as important as knowing how and where to charge. As more EVs hit the road across St. Louis, chargers are becoming a shared resource. Knowing the expectations at public stations not only keeps traffic flowing but also makes you a considerate member of the growing local EV community.

This guide breaks down the essential EV charging tips for St. Louis drivers, from sharing Level 2 chargers at grocery stores to navigating popular DC fast chargers along I-64, I-44, and I-55.

What Are the Rules for Using Public EV Chargers?

Public charging stations—whether they’re part of Ameren’s network, ChargePoint stations in downtown St. Louis, or Electrify America chargers near retail centers—operate on a simple principle: charge your vehicle, then move so others can do the same.

Basic expectations include:

• Only park in a designated EV charging space when you’re actively charging.
• Follow any posted time limits (common at workplaces or retail stations).
• Don’t unplug other vehicles unless you have clear permission.
• Keep charging cables neat so they don’t become a tripping hazard.

Following these rules helps keep public EV charging in St. Louis accessible and frustration-free for everyone.

How Long Should I Leave My Car at a Charging Station?

This depends on the charger type:

Level 2 Chargers (Grocery Stores, Hotels, Parks, Etc.)

These are slower chargers meant for top-offs or longer stops. As a rule of thumb:

• Stay plugged in only while you need energy.
• Avoid leaving your EV for hours if the lot is busy.
• If you’re done charging, move your car—even if you’re still shopping or dining.

DC Fast Chargers (Highway Corridors, Travel Centers, More)

Fast chargers are high-demand resources. Etiquette here is stricter:

• Unplug once you reach 80%, since charging slows dramatically afterward.
• Move your EV as soon as your session completes.
• Don’t treat a fast charger like an all-day parking spot.

In crowded areas like Brentwood, Maplewood, and downtown St. Louis, being aware of charging flow makes a big difference.

Is It Rude to Use a Fast Charger If I Don’t Need a Full Charge?

Not at all—but there’s nuance. Many experienced EV drivers in St. Louis use DC fast chargers for quick “splash-and-dash” charging, even if they only need 10–20 minutes of power. That’s completely acceptable.

However, it’s considered poor etiquette to:

• Use a fast charger when a Level 2 charger would be more appropriate
• Stay plugged in past 80% on a busy day
• Treat fast chargers as free parking

Because many fast-charging stations around St. Louis (like those in Sunset Hills, Chesterfield, and South County) can get congested, the goal is to keep the chargers open for drivers who truly need them.

What Happens If a Gas Vehicle Parks in an EV Charging Spot?

This is called “ICEing”—when a gas-powered vehicle blocks an EV charging space. It’s universally frowned upon, and many public parking areas in St. Louis issue tickets for it.

If you arrive at a charger and find a gas vehicle taking up the space:

• Don’t block the car or confront the driver.
• Report the issue to the business or parking manager.
• Use an app (like ChargePoint) to flag a blocked station.

Fortunately, ICEing is becoming less common as EV awareness grows throughout STL.

Are There Apps That Help With EV Charger Availability in St. Louis?

Yes! Several apps make finding open EV chargers in St. Louis much easier:

• PlugShare: Best for community updates and charger reliability ratings.
• ChargePoint: Useful across universities, hospitals, retail centers, and workplaces in STL.
• Electrify America: Ideal for fast-charging along I-64 and I-44.
• EVgo: Great for quick-charge stations near major retail hubs.

These apps help you plan trips, avoid busy chargers, and check whether a station is down or currently occupied.

Final EV Charging Tips for St. Louis Drivers

To make the public charging experience smoother for everyone in STL, keep these quick reminders in mind:

• Charge only as long as you need.
• Avoid occupying fast chargers unnecessarily.
• Keep cords tidy.
• Don’t unplug others.
• Move your car once charging is complete.

Use apps to plan ahead: especially at popular spots in the Central West End, Clayton, Kirkwood, and South County.

As EV adoption continues to grow across St. Louis, understanding these unwritten rules helps keep our city’s charging network running smoothly.
