Denver International Airport (DIA) is to receive 10 additional (Level II) EV charging stations in its west parking garage, over the 10 Level I 120v units that have already existed there since 2013 in both the east & west parking areas.

DIA claims these new chargers will cost approximately $85,000 dollars, but $32,000 of it will be taken care of by “Charge Ahead Colorado Electric Vehicle and Charging Station grant fund.”

In fact, a few of these Level II chargers are already in place. Also, Kim Day, DIA CEO stated:

“Since adding electric vehicle charging stations in 2013, we have seen a tremendous response from passengers and an increasing demand for charging stations.”

$8,500 a pop for a 30 amp, 200 volt station? Gimme a break.

If these are all clustered in the same area there is only one pipe that needs to be buried to the ‘charging Kiosk’ and an outdoor panelboard with 20 spaces can power the individual units from there.

Sounds like a Scam to me. Long term parking only needs Level one obviously, so these must be for drop offs or taxis.

Not sure how long their runs are, or how much other infrastructure they need to work around, but at my employer, a simple run across a parking lot and about 50 feet long was close to $40,000.

I’m sure that cost quickly increases in an infrastructure-heavy and security-laden place like an airport.

Yes it seems high, but don’t forget that they can only use companies cleared by the TSA to install the units. When the work is being performed, airport security will have to be present, etc. They may even be limited on equipment provider. There may also be some additional improvements lumped into this.

“There may also be some additional improvements lumped into this.” And those improvements may or may not be airport related.

Governments at all levels in the US often lump weird things together in funding bills to get enough votes.

Oh yes, we wouldn’t want Osama Bin Laden to install a 2″ pipe.

Oh I forgot, he died of kidney failure in 2001 before dieing a few more times.

Give ME a break – clearly you haven’t been involved in any charge station installations in anything but residential contexts. Did you notice how PG&E is budgeting for $25k per L2 port in their massive deployment? You can bitch and moan about how these things should just be like a simple extension cord and should cost $300 all-in, but in reality, when you need to modify existing buildings and parking lots to retrofit them with EV infrastructure, it ends up costing more than extension cord.

The big expert has spoken. You have no idea what piping or wire sizes are required for 10- ’20 mile range’ docking stations nor what ancillary equipment is required nor other variations in choices to minimize pressure drop to the car.

PG&E spent $7 Billion on their Bogus smart meter program. Former CPUC commissioner Loretta Lynch says the current CPUC is ‘a Rogue organization’, and basically does what PG&E wants, but that was covered in a former blog.

Fair enough. Let’s see if Mustang_Sallad can solve a typical problem with charger installations since he knows everything ther is to know about it.

Let’s say, its been decided that the 10 docking stations to be installed are SunCountryHighway 24 amp CS-30’s.

The nearest electrical room is 500 feet one way from the outdoor parking lot ‘charging Island’. The most straightforward way to hook these up was initially attempted – 3 #10 American Wire Gauge Copper wires per unit, terminating in a new 208 volt distribution panel in the electrical room.

Unfortunately, the first Honda Fit that attemped to plug in kept kicking out. A voltmeter showed that the voltage at the car was only 176, not enough to make the car charge.

What simple change should have been done to end up spending LESS money on the installation and have the voltage be sufficient to be successful?

Now, you’re just trying to make fun of me.. A single phase charging dock in the states sends 120 pulses of juice per second to the car’s charger. But that doesn’t fix the Honda Fit EV problem. The voltage is fine at the car until the charger actually draws current. My point is, If people think they are such no-it-alls and can dispute someone’s pricing argument, lets see if they have any idea of the infrastructure requried or are just squawking silliness. Someone who is familiar with the problem could solve that simple problem I gave. There was a guy a few years back on PLUGINCARS ‘objective’ who claimed he knew ‘everything there was to know’, and ‘forgot more than I’d ever learn’. I countered he was just a 14 year old kid. The only thing that finally shut him up was, I gave him a problem of hooking up a standard dual ‘4500’ watt water heater sold in any Big Box store installed in the downtown area of any major city in the states. I asked him, a few questions, since he ‘knew everything there was to know’, so he said. 1). Since the supply is 3 phase, but… Read more »

typo: Know-it-all. Of course, no is probably more apt.

Spend $1000 on a 75kVA transformer and bring 480V out to the charging island. You’d save a couple thousand on copper and avoid the voltage drop issue.

That’s one way to do it. Congratulations. I was thinking about a solution which would have effectively avoided the transformer. But seeing as the airport is most likely 277Y/480 dist your method would work.

What was your solution?

In my employer’s installation, Copper was immaterial in the cost. The trenching, conduits, getting electricity out of the building, and of course all the associated labor, was far more than the copper. Though I agree this is one way to save on the copper cost for sure.

i wonder how these stations will be managed? i mean, if you are taking a flight, the car will recharge and you will remain plugged in and occupying the charging station until you return.

stapleton was so much more convenient than dia!

Exactly the reason to have Level 1 charging for long-term parking. L2’s should be priced higher (the DIA L1’s are free).

BWI (Baltimore) offsite parking ( has a nice system where you give them your arrival time and a valet plugs you in for enough time so you’re fully charged when you land. This almost completely eliminates cars parked but not charging.

that does sound like a nice system. hopefully the cord is very long so that the valet can move the EVSE to recharge cars in other parking spaces in the area. of course, if you have a chevrolet volt, and alarm will sound when you unplug the vehicle when the door is locked so that might be a bit of annoyance for the valet.

Most Volt owners that have neighbors disable the plug alarm within the first week of ownership. It’s cheaper to have your cord stolen than having your Volt keyed and tires slashed.

This is a serious question: Can I really disable the charge cord ‘alarm’ on my 2011 VOLT? Or was that a feature just on the later volts?

Bill: The dealer can do it for you.

So I’m assuming this option was available on the touch screen on the later volts? Thanks.

It does seem odd that they would add L2 chargers. Seems like many more L1 chargers could be added for the same cost (?). I could sort of see a mix of L2 & L1 chargers – but if you are flying somewhere, you’ll at least be gone for most of the day. 8+ hrs. I suppose a mostly depleted 85 Kwh Tesla might need that to recharge in 8 hrs – but that is the extreme higher need with the extreme shortest time duration. I think it was Atlanta that had a long row of outlets for L1 charging – that seems much more sensible.

Perhaps these are in short term parking. I know that the Nashville International Airport recently installed two L2 and one CHAdeMO unit under a solar panel array on the top deck of their short-term garage.

Also if you consider that in 2-3 years there will be EV’s with double the range and probably three times the range in about 6 years, it makes sense to go ahead and put in L2s. In fact you could lower the power on them to 3.3kW or less right now and up the kW in the future.

The 10 DIA level 1s are so popular that they are invariably occupied by 6 am Monday and not open until end of the week. More level 1s would have been great. Level 2s don’t make any sense, especially since most users at DIA are Volts, in airport parking unless it’s in a short-term lot.

DIA could add 10x the number of level 1s and still they’d fill up.

DIA does definitely need to tow away any non-plugged in EV ICEing those spots, too.

What a horrible waste of money. Level 2 EVSEs are nearly useless for airport charging.

Most vehicles are parked at airports for more than 24 hours, and level 1 charging would be fine for these cars. For the same amount of money, they could have installed dozens of simple 120V outlets that are free to use, a few L2 stations (and charge a premium to use them so only the people that really need them will use them)and a DCQC station for those dropping off or picking up passengers.

Tom, sees like as useful as NY State installing Level 3 chargers at Thruway stops.

1). Too much money.
2). If they’re not both CCS and Chademo, then 1/2 the fast charging cars are going to be helpless.
3). We Roadster owners will still be left stranded.

Well, 2 and 3 are easily solved, but it might exacerbate 1. I agree they should be both CHAdeMO and CCS, with multiple bays. It would be nice if they also installed some 80A/240V EVSEs as a backup/overflow, which could be much cheaper than more quick chargers. That would also help out the Roadster owners that venture through. But let’s be realistic – I think we need to build our infrastructure with an eye towards the future and not the past. In the future, all new “real” EVs will have a quick charge port. They will also have enough range to skip a rest stop (i.e. at least 100 miles at highway speed). We shouldn’t cater to either the pre-QC roadsters or the current crop of 80 miles-in-San Diego-weather-at-60MPH EVs.

You realize you just eliminated every current EV on the market.
