Question re: ChargePoint charging stations?

Question re: ChargePoint charging stations?

There have been 40 of these charging stations added at San Diego airport. I pick up my MS (first EV car I have owned) next week and travel/fly often for work. I see there is a charge for use of these charging stations. Assume I input my credit card. How would I be billed? ... If I keep this plugged in for 4-5 days while I am traveling, do I pay for only the time the car draws electricity? Does anyone know approx how much the costs would be? Thanks! | August 21, 2013

Generally need a ChargePoint RFID card to use their stations--head over to to join. Normally, you can go the the ChargePoint website and pull up a station and see what the type of chargers, costs etc are, but I don't see the airport on the charger map.

As for whether its kosher to leave your car plugged into a charger for 4-5 days, I am pretty sure you will get a diversity of opinions on the advisability of that. :)

BTW, congrats on the new MS. :)

You're also going to need an HOV decal to park and charge which really kinda sucks since not everyone who owns an EV/PHEV in CA bothers to get one. Ref: I suspect the Port Authority thought they were doing us a favor by keeping the EV parking from getting ICE'd, but you'd think an "EV Only" parking sign would accomplish that without requiring the HOV decal too.

Thx for the feedback!

@omarsultan- I'm new to the EV world...Is there "EV etiquette" around how long one leaves a car hooked up to these charge points? If so, I assume it would to give other EVs an opportunity to charge?? Just not sure how this is alleviated at airport Pking when one travels for days/weeks at a time. Any thoughts?

Yeah, this topic brought on a vigorous debate about etiquette. There were two basic positions which were;

If the charger is free when you get there, it's yours and time is not relevant. First come, first served.


The chargers are limited resources, and you should not occupy a charging space if you are not charging.

As to my own behavior I move my car immediately when done charging, as my non-charging car is occupying the charging space. It's no different than if I parked an ICE car in front of the charger.

I'm going to make popcorn in case the debate starts up again.

Not Kosher to hog and monopolize a charge for days at a time - were you serious? How would you feel is someone takes up a charger for even a full day while you are waiting in line to get a charge?

Airport charging is a little different etiquette-wise to others as the owner might be on an airplane while the car is kept charged. I'm in the Boston area and called the Logan Airport parking officials to ask specifically about their policy (other airports may have different policies, I would call your airport and get an authoritative answer). Logan's policy is that as long as a car is plugged in, it can stay in the charging station spot indefinitely. At Logan, these are Level II chargers - I pointed out to them that for long term parking, simple 110V would be sufficient and perhaps better to provide to a greater number of customers, I'm sure this fell on deaf ears. Personally, I only live about 30 minutes from Logan and wouldn't need the chargers - so instead paid for Logan's "Passport Gold" program which offers reserved and guaranteed parking which I perceive as a safer area to park an S (near other folks willing to pay extra for parking who probably care more about their cars than average and might avoid dinging doors etc), and would tend to park there rather than hog a Level II charger I don't really need.

I spoke with another S owner at a Tesla store when I went for my first test drive and asked the question "Would you park your S at Logan?" - he said that he just did, in fact, and enjoyed effectively a prime parking spot by plugging in. EVs are not yet that common here in the Northeast so charging stations are underutilized (as compared to California I suspect) so there isn't a lot of conflict - but hope that begins to change as we see more EVs on the road.

Ultimately it would be best if charge station owner/operators posted rules with better signage to set clear expectations, and always helpful to leave notes to other drivers about your charging needs (i.e. okay to unplug after 3PM, please plug me in when you're done, etc).

@201w77 The last heated discussion about Charging etiquette revealed this nugget: If you are about to unplug and there is an EV within range of your charge unit with the charge port open, that is EV code for "Plug Me In."

@stevenmaifert The California EV sticker for charging requirement was repealed almost two years ago. All you need to do is to be plugged in.

stevenmaifert | August 22, 2013

@Dcp9142 - Okay, but the charging stations and that sign were put up recently in conjunction with a major remodel of Terminal 2.

Uh oh. Not this discussion again. jbunn, will you share that popcorn? I'll bring the beverages. ;-)

stevenmaifert | August 22, 2013

So if you get a ticket, take this memo to court: No butter on my popcorn please :)

jbunn | August 22, 2013

Large sodas anyone? | August 22, 2013

My two cents is that your charger occupancy should match the kind of lot you are parked in. If its an hourly lot, then don't camp out, but if its a daily or long-term lot, then its kosher to stay plugged in for the duration of your trip.

I know there are folks that passionately disagree with this perspective, but I have not heard anyone propose an alternative usage scenario for chargers in daily or LT lots--how else are they supposed to be used?

(ducking now)

No butter and Sprite for me please!

Not that my opinion matters much (as I don't have an EV yet) but I agree with omarsultan. If it's a charger in a long term parking lot, plug in and don't worry about it.

jbunn | August 22, 2013

Popcorn, Omar?

Well, there were a couple suggestions on that.

One is for airports to put in Nema 5-15 adapters in long term parking. They are the standard wall outlet you get in your house. Dirt cheap, and do not require a big expensive electrical service or a charger. Install them by the dozens. If your Tesla is on a charger for 4 days it will be full when you get back, even if it's empty when you get there.

The other was valet. Not all that crazy, really. My favorite lot at SeaTac had valet at no charge.

mdemetri | August 22, 2013

As the OP says there are 40 charging stations, it is pretty hard to see how all 40 will get occupied (at least at this early point in the EV evolution). Plus, if it is an airport long term parking lot whose purpose is to allow people to park their cars while they fly, it should not be an issue at all to park/charge in one of these spots while away; although I agree with confirming with the airport first on their policy.

I will take salt and butter on my popcorn.

Any update on the San Diego Airport EV spots? Are they operational yet?
