Porsche To Install 350-kW Charging Stations At Headquarters In U.S.

OCT 25 2017 BY MARK KANE 34

Porsche received a permit this Summer for remodeling the existing parking deck at its headquarters in Atlanta, GA to handle six electric vehicle charging stations. The construction will cost $96,800.

Porsche Mission E Concept

It’s expected that these units will be the company’s new 350 kW fast charging stations, that were also installed in Berlin in July. The U.S. version will be of course equipped with different plug – the CCS Combo 1 instead of Combo 2.

It’s not clear at this stage, whether all six stalls will be 350 kW DC or not; as in Berlin for example there are two DC stands and two Level 2 AC.

The 350 kW charging at 800 V is one of the main features of the upcoming all-electric Porsche Mission E, which was promised to charge up to 80% in 15 minutes.

Good step for Porche.

Goo luck!

Same as all other car manufactures, install chargers at their headquarters or dealerships. Where is the charging network??

Well, since there are currently no cars that use them, why would there be charging networks
for the 350KW CCS Combos? With electric cars, there is no end to consumer fears and
mistaken assumptions.

Once these are up, someone in GA should get a Bolt over there!

Then we can see if it can charge at a higher rate or if 55 kW is indeed the max! 🙂


Testing with a 100 kW CCS station (Up to 200A / 500V) showed a max of 55 kW and 150-160 A draw. This is an improvement over 125A stations (50-60 kW) which provide around 44 kW real power to Bolt.

350 kW CCS (typically up to 350-400A / 800-1000V) is unlikely to charge Bolt any faster than existing 100 kW stations.

I thought the Bolt was able to charge “up to 80KW”.

Was that another Lie from GM???

I have not seen anywhere that GM has claimed Bolt could accept an 80 kW charge rate. I think perhaps it is not that they have lied but rather that they have not clearly stated the Bolt’s DC capabilities.

They have variously claimed in different places that Bolt required an 80 kW charge station to charge at its maximum rate – notably this would probably be 500V and 160A, which matches the maximum 160A draw seen above on a 100 kW station.



Fundamentally this is no different from a Tesla Supercharging station offering up to 145 kW but real charging rates being somewhat less depending upon SOC, temperature, etc.

If I remember correctly it’s under “ideal conditions”.

No, GM is referencing an 80kW station because with their power ratings assuming 500V, those stations are the ones that have sufficient current to max out the Bolt’s current charging capabilities.

It’s precisely why people had to test the Bolt on a 100kW station to observe the maximum charge speed. They could’ve done the same with an 80kW station. But less than 80kW and it’s the station that maxes out on charging current, not the Bolt.

GM has never lied about any capabilities except when people let their biases lead them to believe otherwise.

It wasn’t a lie.

What GM said was that to guarantee the maximum rate you’d have to charge at an 80kW+ _charger_.

This was then misinterpreted by some GM fanbois and other overenthusiastic EV supporters as they let their biases and enthusiasm get in the way of English comprehension.

Chargers are commonly rated for power at 500V, and 80kW is 500V x 160A, so what GM meant (but didn’t say explicitly) was that the maximum supported current is around 160A, so maximum power would be 160A x pack Voltage, which is what gives the mid-50skW max rate.

Some people were _hoping_ that they were saying 80kW based on 400V chargers, which would have meant a max of 70kW, but that wasn’t the case.

Really, GM gave the signal early with the Bolt preview saying that DCFC would give “90 miles in 30 minutes” and generally lacking enthusiasm in answering EV Owner Question 2 (How long does it take to charge?)

90 miles in 30 minutes is achievable on a 125A charger. I’ve done it and then some. Any higher charge max would exceed these figures by a bit more.

So the figure is likely an understatement. But only a slight one. Tesla undersells their speed on their website too.

GM never said that. They said for max charge speed they recommend using a DCFC with an 80kW rating. They didn’t even say “required” as the other poster says. Nor did they make any guarantees as the other other poster says. They just said for max charge speed they recommend using an 80kW charger.

So the lie here is your own.

‘I thought the Bolt was able to charge “up to 80KW”.

Was that another Lie from GM???’

No, it was wishful thinking, rumors and fantasies from limited wits fan crowd.
“80 kW of available power” at charger (as in Bolt manual) means 160A at 500 V – 500 V is maximum rated for this CSS version. 160 A is exactly what was observed in practice. But Bolt battery is not 500V, it is below 350 V at lower state of charge when battery can take more ampers. kW may increase a bit as you charge more and voltage gets closer to 400V, but then amperage limitation kicks in.

Thanks I missed this conversation!

So it looks like a bit over 55 was the highest it reached? Would still like a follow up test from someone to confirm. 😉

Oh well, even at ~ 47 kW on a recent just took a 600+ mile vacation, our Bolt only took about 45 minutes longer each way than it would have in my Volt. Perfectly reasonable for me. 🙂

350KW? seems a little unnecessary and overkill to me.

You know 640K should be enough for anyone.

It’s better to have an upgraded CCS standard that supports much higher charging rates so the EV manufacturers have room to grow.

I’d rather these 350kW chargers start being installed in mass than the current 50kW which are already outdated. Hopefully, the electrical infrastructure on current 50kW installs are enough to support swapping out for higher kW units.

350 kw is just fine as long as you can find someone who’ll pay for the party.

I think its a scream that some Nissan dealers ‘set’ their fast chargers to only around 12 or 13 kw to prevent running up the electric bill.

Only saw one article on that here some time ago. Must qualify as the ev version of ‘dirty laundry’. Or else it was just one dealer – but all dealerships copy each other’s money saving ideas.

Personally, around my area many dealers are shutting off their wallboxes out of hours, when initially they left them on 24/7. Must be an issue of when there are next to no ev’s its not an expense, but now that they are getting somewhat more common its time to shut them down.

800 V charging is the bigger advancement that will allow double the charging power at the same charging current. This should increase charging speed for those EV’s capable of 800 V charging.

Good. Now they need to install about 8000 more plugs.

Cool. Only 1,083 miles away from me!

*looks up*

So that’s 6 total across the world? Wake me up when it’s a few thousand.

*puts head back down*

Serial anti tesla troll thomas

Tesla has some thousand chargers but no M3 ???

And Porsche have no Mission either?

What a loser, Tesla has already made many tens of thousands of cars and very soon the beautiful Model 3s will soon hit high rate production levels and start eating into sales of midrange luxury ICE cars.

They have over a thousand locations with over seven thousand plugs.

Very funny

Well, it’s 6 more 350kW stations than Tesla

The pictures in this article are misleading. Just as the ‘120 kw’ Tesla Superchargers are more than the ‘dispenser’ that attaches to the car, so the actual 6-phase charging equipment is at the other end of the parking lot out of the picture. The initial articles on these things at least showed the stuff at a distance.

Forget 350 kW….are there ANY CCS stations 100+ kW in the US?

Yes. There is at least one. Not publicly usable though.


It’s right near the Tesla plant. Probably not by coincidence.

The 350kW is most certainly a 1000V 350A charger, which means that for the current cars it’s 350A that’s interesting, which means 175kW.

Royal Dutch Shell just bought a charging company, for the obvious purose of installing chargers where they really belong – at gas stations, not motels or restaurants (Tesla). Gas stations have the established locations and infrastructure and are everywhere, which is what we need, not a Tesla supercharger stations 40 to 50 miles apart – that is absurd and of benefit only when traveling. Auto companies in Europe have banded together to establish 400 CCS Combo stations but auto companies have no business gettinginto the charging and snack business
(which that “visionary” Elon Musk recently
added to his supercharger stations – a concept about, oh, 50 years old.) The countries fleet will need upwards of several million public charging pods – Tesla’s supercharger network (5,000 strong in the U.S.) will become a bad joke.
