Tesla CHAdeMO Adapter Tested In Georgia


Some Tesla Model S owners have been waiting for the arrival of the “eternally delayed” CHAdeMO adapter. Finally, few owners in Metro Atlanta (and elsewhere across the U.S.) have received the long-awaited package.

Matthew McInerny did just that and took his brand new adapter for a fresh spin at one of the Nissan Dealerships in Metro Atlanta. This test was at a dealership charger connected to the new NRG eVgo network, therefore allowing anyone with a CHAdeMO connector and the right access card to charge. This migh eventually become an issue at some point, but the Tesla Model S is now fully capable of using the DC CHAdeMO connections at up to 50 kW.

The image below shows a draw of 37 kW, but that low figure is probably due to some very cold temps Atlanta has experienced recently.

The reason Matthew purchased the CHAdeMO adapter was to expand his ability to reach destinations not currently served by Tesla’s Supercharger Network and it seems this adapter will do the job!

The recent price reduction to $450 will make this a very popular accessory. It also might take the pressure off Tesla to offer in city SuperCharging.

eVgo in Houston has many CHAdeMOs at grocery stores (HEB). A stop for groceries would provide a weeks worth of range for an inner city driver.

What’s the cost for an eVgo fast charge in Houston?

I had a three year subscription tied to the 3 year lease of my LEAF. It was $90/mo which included the installation of my L2 in my garage ($2k quoted from Nissan), unlimited use of their network of charging, and all off-peak electricity used from my home charger. I used the DCQCs 2 – 3 times per week, so it was a good value for me.

The eVgo business model has changed since I signed up. I know they offer per charge rates in other markets (CA) and free 2 year use for new LEAF purchases now.

Thanks. I couldn’t find the website when I searched earlier; I must have mistyped. Unfortunately, they are not yet in my neck of the woods.

Here are the rate plans if anyone is interested:



Tesla’s solution for in-city charging is HPWC, offering about 60 mph. I think it’s a great solution, they can be much more widely distributed for the same cost.

You don’t need the same dispersion at mid-points between cities, but you do need faster charging.

It seems they are focusing the HPWC as destination charging at hotels, service and sales centers. These would not be convenient locations for city dwellers without designated parking spots.

Food, grocery, coffee, etc. would be better locations for city dwellers.

Also, you need Dual Chargers ($1200? extra) to get the 60 mph.

Dual chargers were $1500 as part of the initial order but as of a few days ago aren’t available any more as part of the factory build and are a $2000 “accessory” installed at the Service Center. This brings the minimum price up although it’s a price cut for anyone who wanted to add it on later, since the old add-on price was $3600.

Not clear why Tesla did it, but it does seem to bespeak a lack of confidence on Tesla’s part in the HPWC as their in-city solution.


I think it’s less a matter of “lack of confidence” than the reality that so few people really need to charge at 60mph unless they’re on a road trip.

It’s fairly unusual to drive more than 200 miles in-city in a single day.

Fast in-city is helpful if you’ve just arrived at your destination city without any range to spare, and still need to drive around town.


That’s true Josh, that is where they are focusing the new installations, hotels, since with a Model S, you almost never need opportunity charging in town, unless you just got there from somewhere else. For most people after a long trip, that’s a hotel (or friend or relative’s house).

I have used HPWC chargers at malls with Tesla stores, generally conveniently sited. Although I agree that service centers are sometimes not ideally located, they are a welcome addition, and cheap and easy for Tesla to provision.

If every decent sized mall had a row of HPWCs, it would make for a pretty comprehensive public charge infrastructure for folks not in transit between cities.

Throw in the CHAdeMO adapter, and the situation is the best of any on offer.

I’ll say one thing about Tesla’s vehicle connector, it’s very well executed, in that it allows a lot of current to go through a very small sized connector. This becomes even more evident when you see it connected to a Chademo connector as shown above. 🙂

Agreed completely. I have handled both cables/connectors, and the Tesla is far more elegant and manageable. The Tesla Supercharger cable was on par with managing a gasoline hose. The CHAdeMO charger was like handling a very stiff fire hose.

“The image below shows a draw of 37 kW, but that low figure is probably due to some very cold temps Atlanta has experienced recently.”

Do Tesla Superchargers also experience such a drastic drop in output in very cold temperatures?

According to the charging station, the vehicle has only been on charge for a minute. It may take a few minutes to ramp up to full power. I doubt this has anything to do with the cold as the battery would have been warm when the car pulled up.

D’oh! I didn’t see that it said “Elapsed time 54 seconds” on my tiny smart phone screen. Thanks.

These things are only rated at 44kw @ a 480 volt input. And the output voltage is unspecified in nissanqc.com. So there’s plenty of unknowns here as to why it was only 37 kw.

Great report, thank you for putting this together!

37kW is par. I’ve charged from near empty at many Atl dealerships and sometimes I get 25kw, sometimes 40kw. I’ve gotten as high as 48kW at the LaGrange, GA dealer. (I use an OBDII bluetooth adapter and LEAFSpy for Android to see the charging power level, along with many, many other things from the car’s computer.) It was a small cute brand new Chademo unit installed in December.

I don’t know what factors go into deciding what your peak output during a charge are, whether determined by car or charger, but you almost never get peak spec, like the 48kW instance.

Yes, I know, the Tesla would be hungrier for longer during the charge cycle, whereas the LEAF may only be able to pull the max Chademo 50kW over a single minute and with the right battery temp. So, I think the charger just wasn’t going to pull that much off the grid or it wasn’t the right temperature or something. I’m pretty sure different units have different power levels configured on their power grid connections. They ain’t all the same!

Not sure I’d want to leave that $450 adapter sitting unattended whilst charging.

That’s the problem with adapters, they’re pretty easy for someone to steal. Fortunately one doesn’t have to wait too long for a DC charge.

Doesn’t the adapter lock to the car?

The adapter is locked to the car while charging.

A Tesla can lock the EVSE connector in its charge port thus preventing theft of the adapter.

Good to know… Locking certainly makes it more practical. Kudos to Tesla for thinking about that.

Is the Tesla lock easy to defeat like the Nissan LEAF lock?


The way you’d do it is unbolt the CHAdeMO station, pop up the trunk to stuff it in, and drive away, no need to unplug 😉

Lets hope Tesla vehicles arent hogging up the single Chademo chargers when a LEAF is waiting that really needs it to complete a trip.Not very fair when the LEAFs are usually only there for a shot period and the Tesla could be there for an hour. Besides the fact that LEAFs are not welcome to use Tesla DCFC stations. Its bad enough that I have seen countless Teslas at local mall parked in EV spots without even charging. Often blocking the Chademo stall.

Well, Tesla figured out how to make a CHAdeMO adapter, so maybe Nissan can figure out how to make a Supercharger adapter for their owners to use the Superchargers!

Worst case, it should not cost much more than the upgrade for the 60 kWh Models S: $2,000.00! Maybe a bit more, allowing for hardware costs and as part of the fees to Tesla for access?

Wonder how Nissan Corporate feels about their CHAdeMO chargers at Dealer Locations, being used by Tesla EVs?

Well, at this point Nissan isn’t really competing with Tesla. The Model S & Leaf aren’t comparable, neither in price class, nor range-wise, nor size-wise. I doubt anyone cross-Shops the S with a Leaf.

Both companies have a significant commitment to BEVs, and need to continue to support it in these early times including with the charging infrastructure issues. Bottom line, I really doubt Nissan Corporate cares.

This could change when actual competing models come out, like a BEV Infiniti, or the Model 3 (although I suspect even the 3 will be enough upmarket of the Leaf that it only partially competes).

That said, I’m also pretty sure this is up to the individual dealer. They could certainly give Leaf

I remember early on that Nissan dealers were getting very upset when non-Leaf EVs tried to use their level 2 charges. Lots of driver comment were posted on Plugshare.com.

I think Wavelet comment is correct about Nissan corporate but the dealers will not like free charging for cars they did not sell. This will be an issue and right now Tesla owners are buying a CHAdeMO adapter to use the Nissan charges. Other CHAdeMO charges are only in a few cities today.

Since Tesla figured out how to make a CHAdeMO adapter, so maybe Nissan can figure out how to make a Supercharger adapter for their owners to use the Superchargers!

It should be able to handle the task of communication between the car and Tesla’s Supercharger, and Identify itself to the Supercharger for Tesla to keep track of the ‘Other’ cars using the network!

Physically it could maybe be even nicer, as it is going from a small plug into a bigger one for the LEAF! Just needs to be long enough cable between the ends, so it can reach the short Supercharger cable to the front if the LEAF!

And – if not Nissan, maybe KIA could lead the charge! Since the Soul EV has already been tested and charged at up to 100 kW, moving to 120 kW should be manageable!
