How to Tell if an EV is Finished Charging . . .

69984 Views 64 Replies 37 Participants Last post by  jjerry32
So, when at a public place with EV chargers, if other EVs are plugged in, I would like to know when they are fully charged so that I can take the plug and charge mine. This, of course, is assuming I can get a parking spot close to the existing EVs.

Let me start by saying the list below is predicated on the assumption that it is acceptable to unplug someone else's EV when they are done. Assuming this is acceptable etiquette, should we leave a note saying that since their charging was complete, we took over the charging cord? Hopefully, the owners haven't set the charge cord's anti-theft system!

At any rate, I'm planning to keep this particular message updated with all the EV models with their indication of being fully charged. Please reply if you have information on how to tell if a particular model is charged (or if you notice an error) . . .

BMW ActiveE
Blue light on bottom of center rear view mirror is not illuminated

A blinking blue light indicates charging is in progress.

BMW i3
Green light around the rim of the charge port

The charge port LED light color represents the current status of the vehicle charge:
Flashing blue light means the vehicle has begun charging and turns off during charging
Green light means charging is complete
Flashing red light means there is a charging error

NOTE: If the vehicle's doors are locked, then the charging plug will also be locked and can not be removed until the vehicle is unlocked.

Chevy Volt
Short flashing green light on top of dashboard

A solid green light indicates charging is in progress. A long flashing light indicates delayed charging, which should never be used in a public charging spot when others may be waiting.

Coda
{someone let me know and I'll update this}

FIAT 500e
All LEDs on dashboard are on

The 5 red LED bars on the dashboard provide information on charging and scheduled charging.
The LEDs are numbered 1 to 5 with 5 being closest to the steering wheel and 1 farthest away.
While fully charged and connected, all LEDs are solid on.
While charging, zero or more contiguous LEDs, starting 1 are on to indicate the status of the battery (the more LEDs lit, the more charged is the battery) and then the next one (i.e. LED 1, 2, 3, 4 or 5) is blinking.

While connected and scheduled to charge but not yet charging (e.g. on a timer), there is a "chasing" LED, going 1->5 and wrap back to 1. e.g. 1 blinks on-off once, then 2 blinks on-off once ... then 5 blinks on-off, then 1 and so on.

Fisker Karma
The charge level indicator on the instrument cluster will reach maximum and the charge indicator will turn off.

While the vehicle is charging, the charging indicator light on the instrument cluster will be illuminated and the battery charge level indicator will display the current charge level.

Ford CMAX Energi
Blue ring around charge port/plug is not illuminated

The blue ring lights up in four blue quartered segments while charging and will shut off when charging is complete.

Ford Focus Electric
Blue ring around charge port/plug is not illuminated

The blue ring lights up in four blue quartered segments while charging and will shut off when charging is complete.

Honda Fit EV
The green LED next to the port/plug turns off when it's done charging

If it's flashing, the charging rate has been reduced because of a problem.

Mitsubishi i-MiEV
Red electric plug symbol on dashboard is not lit

Look through car windows at the dashboard to see if there is a red electric plug symbol lit. If it is lit then it is still charging. If it is off then it is not charging.

Nissan Leaf
All three blue lights on top of dashboard are all on or are all off.

Decoding Leaf's triple light set:
  • One flashing light 0-33%
  • One solid, one flashing - 33% to 66%
  • Two solid, one flashing - 66% to 100%
  • Three solid - 100%
  • All lights off - 100%
Tesla Roadster
Solid green lighting around inside of charge port.

While charging is in progress, the lighting inside the charge port area flashes amber.

Tesla Model S
The light around the charge port stops pulsing and the light turns solid green.
Good news: When you plug in the charging cable, a light around the charge port pulses green during charging. When charging is complete, the light around the charge port stops pulsing and the light turns solid green.
Bad news: If the Model S is locked during charging, the charge port light does not illuminate but the vehicle continues to charge.
Toyota Plug-in Prius
The amber electric plug icon next to the charging port is not illuminated.

Th!nk
When only one of the two green lights on top of the dash is lit

When both are lit and linked, charging is in progress. If only one is lit, charging is complete.

Toyota RAV4 EV
Both amber lights (at the bottom of the back side window above the charge port on the driver's side of the car) will be solid or off

There are two amber lights at the bottom of the back side window above the charge port on the driver's side of the car. When charging from less than half a charge, the left light will blink and the right one will be off. Once past half charge, the left light will be solid and the right one will blink. Once fully charged, both amber lights will be solid for only a few minutes after a full charge--they then both turn off. Therefore, it is charging if only one light is blinking (with the other either off or solid on). If both are off or both are on the charge is complete. If they blink in an alternate fashion (one on, other off, then switch), the car is in a delayed charge mode, which should never be used in a public charging spot when others may be waiting.

Then you are a dick !! I will unplug your charger and do not give a rat ass if you like it or not.
From my view this is a reason why the charging infrastucture needs to have lockable chargers. You should be able to park your vehicle and charge as long as you need or wish. If the issue is not having enough of charging points then this should be addressed instead of generating some Code of Conduct between EV drivers.

Certain incentives can be put in place to discourage the improper use. For example parking without plugging could equal to 50$ ticket. Plugging without intention to pay could equal to 100$ ticket (plugin without swiping membership/credit card just to fool the cops). Plugging after full charge could equal to 3x charge rate. And so forth. These penalties might need some tought tho :)
Generally, speaking, I don't know that I agree with a punitive system, or if one exists, it should be enforced on individual business/site level. Just as some businesses have a 20 minute parking section (though rarely enforced, they may tow cars parked there for too long), I think most EV parking spots should have a time limit. Generally, 2-4 hours depending on the site or business. If it is employee parking, there is no excuse for a lack of communication, in my opinion. Either install more charging stations, or have the impacted employees meet to establish a policy.

what's the difference between:

finished charging and has a lockable charger. so other can access it.
and
parking in the spot (preventing other from charging), not charging at all.

you are okay with both ?

Definately inconvenient for the others, just like a full parking lot or double parking. It happens.

Now the real question is why there is 3000 gas car parking places and 4 EV charging places on the parking lot. Would you thow a fit for one person charging a car if the situation would be reversed? I wouldn't like to manage with the problem but instead solve it.

Yell at the owned of the parking place instead of the poor chap who happens to have outdated car.
Mitsubishi i-MiEV

To tell if the car is still charging you have to look through car windows at the dashboard to see if there is a red electric plug symbol lit. If it is lit then it is still charging. If it is off then it is not charging.

Thanks! I've updated the list.
Hi, from someone I know that has a Th!nk here is their telltale:

The Th!nk has 2 green lights on top of the dash. When both are lit and linked, charging is in progress. If only one is lit, charging is complete. The plug release button on a Th!nk does nothing. It is only a mechanical release and has no effect on the charge current. There is no way to turn off the current in mid-charge on a Th!nk except to turn off the EVSE. Unplugging a Th!nk mid-charge can draw an arc and damage the connectors of both the car and the EVSE.
A quick update: On the new (2012-2014) RAV4 EV's, the two amber lights stay on for only a few minutes after a full charge. They then both turn off. A RAV4 EV is therefore charging if only one light is blinking (with the other either off or solid on). If both are off or both are on the charge is complete. If they blink in an alternate fashion (one on, other off, then switch), the car is in a delayed charge mode and probably shouldn't be at a public station.
I'd be careful touching other peoples cars. Some owners like me carry a Glock 22 - and are less stable than I.
Too many crazies out there.
The whole public charging thing for a Volt baffles me. If there is any competition with a full blown EV, it seems inconsiderate to compete for space. In the event you don't get the charge....the 4 banger gets you home. The poor lady in the Leaf is at risk of being stranded.
I'm not responsible for what other people drive. Charging stations are for cars that can use them. Only rules set by owners of stations apply. My Volt texts me when my charge is interrupted. The perp and I would then have a nice adult conversation.
Thanks for all the submissions.

I've updated the list, adding Honda Fit EV, Toyota RAV4 EV and Th!nk.
FIAT 500e

The 5 red LED bars on the dashboard provide information on charging and scheduled charging.

For the instructions below, number LEDs 1 to 5, 5 being closest to the steering wheel and 1 farthest away.

While fully charged and connected, all LEDs are solid on.

While charging, zero or more contiguous LEDs, starting 1 are on to indicate the status of the battery (the more LEDs lit, the more charged is the battery) and then the next one (i.e. LED 1, 2, 3, 4 or 5) is blinking.

While connected and scheduled to charge but not yet charging (e.g. on a timer), there is a "chasing" LED, going 1->5 and wrap back to 1. I.e. 1 blinks on-off once, then 2 blinks on-off once ... then 5 blinks on-off, then 1 and so on.
I updated the list to include the BMW i3 as well as the FIAT 500e. (see Post #1 in this thread).

If you don't see an EV on here that you would like to see, let me know. Better yet, tell us how to tell when charging is complete and I'll update the listing.
GM reversed the meaning of the charge indicator light for 2016 Volt!

With the 2016 Volt, GM reversed the meanings of the Charge Status Indicator light(!) Flashing green now indicates that it is charging (the number of flashes increases as the battery charges) then is solid green when fully charged.

IMO this would be a reasonable system, if solid green hadn't previously meant "charging". But now solid green can have opposite meanings, depending on the model year. GM should have used a different color for charging.

One way to know the difference: the 2016 Volt Charge Status Indicator light is square; on earlier models it's round.

Am I missing something?

Public charge stations (at least chargepoint) display when the charging is over.

Is there a reason we cannot rely on that information on the Charge station to know when the charge is over, and would need to know the car full charge display logic?

That's a pretty reasonable statement and it most cases that would seem to be the best way to determine if the car is still charging or not. Unfortunately, that's not always possible. The Chargepoint station at the mall near me has an LCD screen that is pretty much unreadable during daylight hours. So it's next to impossible to tell if the car is still charging.
Great thread - just the information I was looking for :)
