We’re not the only ones to speak on this, but we’ve seen too many electric vehicles (EVs) sitting at Level 3 fast charge stations either done charging and blocking a station or charging above 80%, meaning very, very slowly. So it we will add our voice to the chorus of EV charging etiquette posts, and we’ll take that last one first.
1) Stop charging at 80%
We’ve seen more confusion about this than anything else related to Level 3 charging, and it all comes down to charge curves. Regardless of how fast an EV charges, each and every one of them slows down dramatically at 80% charge (see the image below from P3). So whatever time it takes to get to 80%, it will take up to three times that time to get to 100%. This is the least efficient way to charge on long trips. You can get half way to the next charge station in the time wasted getting to 100%!
The result is a charger that is not available to another driver, a waste of your time, and its really hard on the battery. Meaning it will shorten its life!
We understand the desire to “fill the tank” angst associated with leaving a battery 20% empty. But trust us when we say that the angst will pass with time and you’ll get along just fine at 80% and less.
2) Use the proper plug
This is essentially for non-Tesla owners. Your car determines the rate at which electricity is transferred to the battery. So parking a Chevy Bolt, which charges at 50 kW, at 350 kW charger does a huge disservice to owners of vehicles that can make use of the faster charger. Your car will not charge any faster than its rated speed, regardless of what charger you’ve plugged into.
Please leave the faster chargers for vehicles that can use them.
3) Move your EV when its done charging, not when you’re done shopping!
This is a primarily time awareness issue, and of course moving your car is again about opening a charge spot for another driver. Most EV’s get to 80% charge in 20 to 30 minutes and your owner’s manual will give you a solid heads up. Also, your car’s app may be able to tell you when charging is finished or close to finished.
So if you’ve wandered off to lunch or shopping, for the sake of everyone else, please come back to your car on time to open a slot for someone else.
4) Know your vehicle’s charge port location
Nearly all gasoline fill locations on on one side or the other in the rear of the vehicle. EVs can charge from similar locations but some are in the front! In any case, knowing which par of the car that needs to be closest to the charge cable will save some embarrassment.
Of course, all Tesla models charge from the left rear.
5) Don’t leave trash behind
One would think all EV drivers are environmentally conscious, but this turns out not to be the case. And unfortunately, charge stations don’t have trash receptacles around, since no attendant is needed! So, if you generate some trash, please be prepared to take it away with you.
6) Never unplug someone else’s vehicle
Unless its an absolute emergency, never, ever touch another driver’s car. You wouldn’t want someone to do that to you (unless you left a note allowing it!) so don’t ever do it to someone else.
7) Level 2 charger time limits
Finally, if you happen upon a slower Level 2 public charger, be aware of any posted time limits. You won’t get as much charge, but others may want a little boost too. Leave when its your time to leave.
In all cases, be considerate of other EV drivers!

EV Charging Etiquette
