The next major frontier in DC fast charging is 350-kW units. Whether it’s Continental’s AllCharge, future Tesla Superchargers, or Efacac’s combo units (to name just a few), EV drivers in the next few years will basically have all the fast charging power they will ever need.

At The Battery Show in Novi, MI this week, the Veefil 50-kW DC Fast Charger from Tritium was on display, and this is basically the same as the 350-kW units that Tritium will start installing in the U.S. in April 2018.

Visually, the only real difference will be changes to the air vents to let the 350-kW unit (which will actually be upgradable to 475-kW, if desired) cool off better, said Marcelo Salgado, Tritium’s sales manager.

Salgado told InsideEVs that the roll out of the 350-kW units will be slower than it took to get us to the current state of affairs with today’s DC fast chargers. Tritium has experience in this space, since it’s worked to put a lot of chargers in the ground with Chargepoint.

This is mostly because the only EV that we currently know of that will take advantage of a 350-kW charger is the Porsche Mission E. Of course, since Porsche is working with BMW, Ford and Daimler on a network of 350-kW stations, the Mission E won’t be the only one trying to plug in to station like the Veefil in a few years. We don’t know what those other vehicles will look like, but it’s safe to say that we can now see how the era of 30-40 minute “fast” charges will come to an end, unless automakers decide to throw absolutely giant battery packs into their EVs.

What’s cool is that the Veefil is built to have both CCS Combo and CHAdeMO plugs on it. If Tritium continues this style with the new 350-kW units, then no matter what flavor of non-Tesla DC fast charging your EV desires, you’ll be all set. End of an era, indeed.

Why can’t they support Tesla’s elegant plug then? I know superchargers are there, but not everywhere.


Tesla’s plug (or rather the communication around it) is propitiatory you can’t use it unless you are Tesla.


Wrong. You can use the TSL02 connector and it’s CCS-ish protocol, if you just ask to use it, from Tesla.


Can you cite a specific contact at Tesla that give’s such permission. I’ve yet to see any such “open” offering.


Tesla’s “open patents” promise here includes both a promise not to sue AND a disclaimer that it is not a promise not to sue. That makes it a legally worthless pledge, which means you take the same risk using a Tesla patent as you do with any other patent.


You just defined proprietary. Their connector and associated protocol. Just because Musk wrote a blog post saying they wouldn’t sue anyone who uses it “in good faith”, doesn’t make it open.

There is a legal process for abandoning a patent, andTeslahas not done that.


And agree not to enforce any of your own patents against Tesla. This is giving them a de facto patent license to all your own patents.

Tesla’s patents are only free if you have no patents of your own that you wish to protect. And even in that case all you get is Tesla agreeing not to sue you unless they feel you deserve it. Which is essentially saying nothing at all.

They’re not really free patents.

It’s possible Tesla would negotiate a more reasonable and enforceable patent swap/license if you were to engage them on it. But there isn’t any record of anyone doing so that I know of.


Patents are largely worthless to a company as a pure asset. They are mostly liability mine fields.

Patent swap agreements are a classic scheme for two corporate entities to shield themselves from BS liability.

Having a patent licenced too you does not give you any product or instructions on how to make a product, it’s solely protect from our insane “IP” laws in the states.


Patent swap agreements are typically negotiated.

No matter how you slice it a mandatory patent swap agreement is not the same as “free”. Tesla’s patents are not free.


Chademo adapter is all you need and tesla sells them for 400 dollars.


It’s not a real standard that’s why. CCS and Chademo are actual standards.




Interesting, but I can’t picture that a 1000 volt/350 kW charging station, cables, and CCS or equivalent adapters would be anything similar to the 50 kW station.

I see these 350 kW as 10-15 years down the road before becoming a mainstream fast-charge solution.

IMHO, Tesla really nailed the Supercharger multi-vehicle shared-charger concept, adjusting charging kW to each vehicle based on both individual vehicle requirements and total station capacity. Chargepoint has realized it and now has an equivalent scaleable multi-vehicle system.

This scaleable system, with modular charge controllers and multiple vehicle heads will be what replaces the current individual vehicle DCFC stations will be changed out to in the next 2-4 years as the long-range EV and DCFC markets explode.


ABB had an identical concept to the supercharger called the Terra 100.X back in 2010, a full two years before any supercharger rolled out. It’s nothing new in the CHAdeMO world.


It’s funny you say that hydra chargers are the way forward for DC when Tesla made a big splash by splitting their 2-stall shared chargers in twain this week as the “Urban” chargers.

I think the way forward includes a lot of different configurations.

George Bower

“I see these 350 kW as 10-15 years down the road ”


I see Tesla introducing them before Porsche has the first production Mission e on the road. They already have liquid cooled charging cables.

If you run the numbers on the new M3 charging speeds it implies that Tesla has bumped the C rate on these new cells 10%.

I’m begining to think the new 2170 cells in the M3 charge at higher C rates than the old 18650’s.

….not surprising since Elon said they would have improved chemistry.

john Doe

It will not take 10-15 years…
More like 2-4 years. Max.
As long as people make money on it – that is.


I think the only charging company to make money to date is Fastned?



Fastned is one of the strongest and serious charging companies. But obviously it is very far from profit in this tiny emerging market. €186,829 sales as of Q2 2017 resulted in €-2,009,524 after personal expenses, capital depreciation and finance costs.


Ev Go has a 350 kw solor charger in California near the worlds largest thermometer. The new leaf can except 150 kw


Yea their one in Austin was defective on cooling and screwed a lot of us over for months…


Why is Tesla lagging behind? They should upgrade their Sup…Slowchargers.


The big problem is, it’s not really 30-40 minutes…Most on the fastest chargers gain less than 100 miles of range and a lot depends on the taper…If you are going on a long roadtrip it actually makes more sense to charge for about an hour and to eat a meal somewhere…

So even with 350KW with the taper, to get 200-250 miles of range could still take a half hour…An awesome achievement yet we’re still not there yet…


I agree with you for the most part.

I think the primary use of 350kW chargers will be to charge even larger batteries at similar rates (in C) to current ones. Trying to charge a 100kWh battery in 30 minutes runs up against practical issues.

A bigger battery will invariably be in a car with lower overall efficiency (i.e. in an SUV) so the increase in charge rate in mph will not be the same as the increase in kW. But if you have one of those big batteries you’ll be happy that you aren’t condemned to mere 100kW charging.

David Murray

I guess my gripe with fast charging is less to do with the speed, and more to do with the severe lack of stations. I know it varies from area to area. But most of the USA is still a desert of fast chargers or even L2 chargers for that matter. I’d rather see more effort put into expanding the network right now than trying to make even more expensive super fast chargers that nobody can use.


Yup. What we need today is multi-handle (4 handles) unit that can provide about 70 kW simultaneously for all. Even Tesla’s average power to 80% is only about 70 kW, and such power would be enough for the foreseeable future.


David and Spark,

You guys nailed it. More fast charging stations, with more stalls per station are what EV drivers need. Tesla gets it, and shows others the way forward. They have lead the horses to water, but they refuse to drink.


mr. M

“Drinking” costs millions in invest. When horses are rare it makes no sense to invest million dollars in waterholes.



to everyone that wants more stations: call your local representatives. Call your state senators. Call your city councils. Call the businesses you frequent. Talk to your employer about workplace charging.

Go to the bank and get a business loan and start your own charging company.

People talk about a lack of charges, but the stations I go to are often empty or only have 1 or two cars plugged in.


Water came before horses. Without water, there won’t be horses.

Don’t call the gov’t! They always f things up (eg. DMV). Better is to contact the electric company and tell them that EV will create demand for electricity, and they can also divert excess renewables without throwing it away.

Dan B.

How are the cables cooled?

john Doe

Usually like a welding cable, that use water cooling. Some use a synthetic oil as a cooling medium.

mr. M

“But it’s safe to say that we can now see how the era of 30-40 minute “fast” charges will come to an end”

No it will not, as Long as the batteries stay around the same, the tapper is dominated from the battery. Only luxury carmaker can use more costly fast charging batteries. So most charging will still take 30 minutes to 1 hour. But batteries can get bigger without waiting longer.

You can now also Charge a 300kWh battery within 45 minutes to near full and then go for another 1000miles.


“Only luxury carmaker can use more costly fast charging batteries.”

You better tell Hyundai with the Ioniq EV and GM with the Spark EV. They are two of the fastest charging EV’s and they are not luxury. Fast charging normally comes down to battery chemistry and how you cool them during charging. Tesla’s can charge pretty fast because of the pack size more than anything else.


Fast charging batteries in the examples you gave are very expensive at this point in time. That is why the battery sizes are so small in these vehicles.

Eric Cote

How much will these things cost? They look pretty slick.


Probably too much to see many of them on the roads any time soon, sadly.

To me, it looks like a retro gas pump. Which isn’t necessarily a bad thing.

Jeff Songster

I have used some version of these in Rohnert Park and San Mateo CA. They worked well for my LEAF… which admittedly only absorbs energy at 40kW I think. Great systems and please keep adding them to the world. The higher the density of DCFCs the smaller the battery customers need to buy. Our 100 mile LEAFs have been useful for all but the longest of trips around our SF Bay Area… and the newer models with the larger batteries make it easier.


I’ve used one.

The display is impossible to read if the sun is on it. And even if you can read the display it doesn’t show its unit name/number often or perhaps even at all. That makes it rather annoying to start it remotely using the ChargePoint app.

And if you do want to start it remotely using the ChargePoint app know that you shouldn’t insert the plug into your car until you’ve activated the charger. If you do this in the wrong order it gives some generic error. You can’t make this error on a regular ChargePoint (AC) EVSE because the plugs are locked into the EVSE when it isn’t in use.

They’re quiet though.


“Salgado told InsideEVs that the roll out of the 350-kW units will be slower than it took to get us to the current state of affairs with today’s DC fast chargers.”

Well, considering that we still don’t have a decent national network of CCS/Chademo DC fast chargers, this would indicate to me that these 350 kw units won’t be around for a long time to come.

So maybe they do install a few in April 2018 as they say, but there is no company spearheading a campaign to make these widespread. Maybe 10 years to get to bad nationwide coverage like we have with CCS/CHademo now?
