EV Charging Etiquette: The Unwritten Rules

How long to leave your car at a charger

The single most-asked etiquette question, and the answer depends entirely on the charger. At a DC fast charger (DCFC), the norm is to unplug and move at about 80%. Batteries charge fastest when they're low and taper sharply as they fill, so the jump from 80% to 100% can take as long as 10% to 80% did — all while you're holding a stall that someone behind you needs. Roughly 20–40 minutes covers most cars from a low state of charge.

At a slower Level 2charger — a workplace, apartment, or retail lot — staying for hours is the whole point, since L2 tops up gradually. The courtesy there is different: move once you're full if anyone's waiting, and don't treat a finished car's stall as a parking space. Many networks now charge idle fees— a per-minute penalty once your car stops drawing power and you haven't moved it — precisely to keep stalls turning over.

ICEing: don't block a charger with a gas car

“ICEing”— from internal-combustion-engine — is parking a gas or diesel vehicle in a spot reserved for EV charging. It's the cardinal sin of charging etiquette for a simple reason: a charging stall is worthless to a car that can't plug in, and the EV that was counting on it may have no backup charger within its remaining range. Some states and private lots enforce EV-only spaces with signage and fines; many don't, so it mostly comes down to courtesy.

The EV-on-EV version counts too. Plugging in and then leaving your finished car parked in the stall for hours blocks it just as effectively as a gas car would — it's the most common complaint at busy sites, and it's what idle fees exist to punish. The rule cuts both ways: charging spots are for charging.

Apartment and workplace charging etiquette

Shared Level 2 chargers at apartments and workplaces are where etiquette matters most, because a handful of stalls serve a lot of drivers. The governing rule is rotate: plug in, get the charge you need, and free the stall for the next person rather than leaving a full car parked on it all day. Because L2 is slow, you rarely need a complete session — even a few hours adds plenty of range for a typical commute, so topping up is usually enough.

In practice that looks like a shared calendar or group chat at the office, a move-when-done norm, and — at apartments — whatever time limits or sign-up sheet the property manager or HOA sets. If your building has no chargers yet, or the wait for the shared ones is getting painful, it's worth running the numbers on a home Level 2 install with the home charger ROI calculator — home charging sidesteps the whole etiquette problem and is almost always the cheapest way to charge.

DC fast vs Level 2: the unwritten rules differ

The etiquette flips depending on speed. DC fast chargersare a shared, high-demand resource — treat them like a gas pump: get in, get the range you need (to ~80%), and get out so the line keeps moving. Camping on a DCFC stall to reach 100%, or leaving a finished car plugged in while you shop, is the behavior that generates “charge rage.”

Level 2 chargersrun on the opposite logic: they're slow by design, so long stays are expected and the courtesy is about sharing over the course of a day rather than minimizing minutes. Don't stretch a cable across an empty adjacent stall to reach yours, don't unplug an actively charging car, and if you're done and the lot is full, move so someone else can rotate in. The per-network reality — pricing, connector, and how likely a stall is to actually work — is laid out in the charging network comparison.

What to do if a charger is broken

Before assuming a stall is dead, run the basics: restart the session in the app, try a different stall at the same site, and confirm your payment method is valid. A surprising share of “broken” chargers are session hiccups or app glitches rather than hardware failures.

If it's genuinely dead, report it— there's usually a phone number on the unit and a report button in the app. Networks fix what gets flagged, and a 30-second report keeps the next driver from getting stranded at the same stall. Then route to a backup. This is exactly why it pays to know which networks are most reliable before you depend on one: uptime record is the best predictor of whether a stall will work when you arrive. The EV charging network comparison ranks the major US networks on exactly that.
