Porsche will remain true to its ethos while making electronics and electrification a “strong brand value.”

Uwe Michael, Head of the Electrics/Electronics Development Division at Porsche, speaks to battery tech and charging times. He also elaborates on software, apps, artificial intelligence, and his team’s plan for how it all fits into the future of the brand.

Michael says that what consumers really want from electric vehicles is fast charging … and he’s right. It’s obviously still one of the biggest deterrents to EV adoption. When asked about Telsa Superchargers, he says that Porsche will revolutionize charging times with 400-800 Volt systems that add 400 km in 20 minutes. He reminds that ALL competitors’ current charging times are twice as long.

According to Michael, the automaker is not simply concerned with fast charging, but also convenience. For this reason, his company will offer home charging solutions for customers.

When asked about longer vehicle range and battery technology, Michael replies:

“Yes, it’s important to us to have a say in all the key properties of the batteries, because the cells in our high-performance sports cars must do more than those in standard cars. The current state of battery cell development means that compromises still have to be made. That’s why a particularly well-balanced overall system is a great boon for us. All the auxiliary units, for example the cooling system, must also be precisely tuned to ensure that our vehicles can deliver top performance over long periods. That’s why we’re building direct contacts with the relevant battery cell manufacturers.”

Michael voices interest in lithium-air batteries but states that these won’t likely be in serial production vehicles until 2030. He also notes that solid-state batteries are another option, though 2025 is the soonest we may see them from any automaker, including Porsche.

Other notable takeaways:

  • Porsche has no priority for Level 5 automation
  • Porsche will offer an integrated home power management system
  • Inductive charging may be offered for homeowners
  • Over-the-air updates are coming and will have multiple applications
  • Porsche is exploring new connected electronic services and apps that could revamp the automotive industry
  • The automaker will employ artificial intelligence and self-learning systems

Michael extensively expands upon many concepts regarding Porsche’s future plans and provides fascinating examples. To check out the rest of the lengthy interview, follow the source link below.

No ground breaking there, but it’s good that Porsche is getting on board and follow what Tesla has laid you for the last 10 years.

Actually, Tesla has NEVER laid me. But I digress…

It seems to me that Porsche has always been an engineering driven company, and is likely to introduce some serious advancements in charging, BMS, and TMS componentry.

It should read “what Tesla has laid out … “

(⌐■_■) Trollnonymous

“his company will offer home charging solutions for customers.”

You mean they don’t currently offer any now????

I hope they mean “Quick charge home solutions.”

when is “will” is the question

400-800volts is a big spread. Can they even do 800v now? Sounds like nothing groundbreaking and techno-marketing babble for the fact that we’re not there yet, and not sure when we’ll be there, but clearly we’re not leading the field!

A small number of 350kW 800V chargers hs been already installed.

But how do we know that those two chargers are actually 350kw? There are no cars that those can be tested with 🙂

They have installed a few 800v chargers in Germany.

I feel like Porsche is being coy on the 400-800v charging. Can the same car do both or will they offer two options? They’ve been pushing their 800V powertrain and the only way for them to go from 400V charger to 800V battery is a massive 150kW boost DCDC, aka cost and mass.

Did some internet research and I was wrong about only 400 or only 800, it will be both for charging. Porsche is basically doing a center tap mid battery and added some power electronics to alternate charging the lower half and upper half with some additional filtering. Somewhat crude but a good compromise considering the alternatives. I’m curious what the final implementation looks like.

Good to hear that the paradigm shifting 350KW charging is still on the table, it will make Mission E the most interesting EV since Model S IMO. Also the first credible “Tesla killer” I think.

Of course Porsche should make sure those 350KW chargers are actually rolled out as well, Tesla does have a 8250 superchargers head start on Porsche that it increases every day.

Once again the whole propriatary charging system. Silly, Silly, silly. Oh wait, I forgot; I have to go to a Porsche gasoline station, not.

No other EVs can charge at super charger speeds. It makes sense that Tesla hasn’t made a deal with anyone yet.

Porsche does not now have nor will have within next 3+ years a solid EV offering (including providing access to an *installed* network of convenient & reliable superchargers for those occasional long distance trips) that can compete against any of Tesla’s S, 3, X, or Roadster.

In the mean time…

Tesla will continue to take away market share from Porsche.

Car sales are a zero-sum game… those Tesla sales are coming at other car maker’s expense… including Porsche, BMW, Mercedes, & Audi.

Tesla will likely sell over 1M cars the next 3-4 years.

Hopefully I’m wrong about Porsche… Because Porsche is a great brand and strong Porsche EV offerings hitting the market soon would be a good thing for both Porsche and car buyers.

Mission e release planned afaik 2019. 2019-2018 = 1. Why do you assume no EV from Porsche comes out in the next 3 years?

@Hand Blix said: “Why do you assume no EV from Porsche comes out in the next 3 years?”

Because likely what we will see from Porsche in 2019 is a public reveal of a “production intent” Mission E that will in late 2019 inter very limited production captured fleet testing/validation… then enter regular production 1-2 years after that.

Also, I had said “including providing access to an *installed* network of convenient & reliable superchargers for those occasional long distance trips”…

It will be a minimum of three years before Porsche itself (the Porsche proprietary 800v Superchargers) and/or a public network of Superchargers is adequately built out.

I very much hope to be proven wrong… it would be great to see the Porsche Mission E added to the 2019 InsideEvs Sales Score Card.

They sell lots of Cayennes and Panameras, and know Mission E, too, will be road car that almost never sees the track. “..top performance over long periods” is a quest that will prolong top margins on internal combustion automobiles.

You get what you pay for. To do “enduro’s” with your local car club, buy a 911. To buy the best street car, go someplace else.

Here’s the issue. The market leader (Tesla) can currently do up to 150kW (realistically up to 130kW) on their chargers and that rate is only available under ideal conditions for the battery (not too hot or cold) and state of charge (low). As you get away from those ideal conditions the charge rate quickly tapers off.

800v or not, you can’t do 350kW without a battery breakthrough. So either:

1. Porsche has a battery breakthrough despite saying they don’t.
2. Porsche can’t actually do 350kW and are just hoping they will figure it out by the time this ships.

Same logic applies to the Tesla Roadster and Semi. Does not make sense with current battery tech.

Why not? Having batteries in parallel would do the job.

No it won’t. The key is the C rate. Porsche is claiming a C rate of 3 times what Tesla is achieving without (one would assume) damaging the battery

for the tesla semi 350kw charging is far less stressful than for current batteries since the c-rate will be far lower.

nissan leaf allows 1,7c
tesla model s allows 1,6c
tesla semi 0,5-1c

explanation: higher c-rate means more stress for the battery.

For the tesla semi it is not about charging rates, but rather about cost if you look at the $30k difference between the two models

You can fast charge at 3C+ on a more power dense/less energy dense cell. This is likely what Porsche is referring too as “design trade offs”. The downside is a heavier battery that costs more with less range. For their customer the car needs to be able to do track days so this makes sense. Expect a 70kWh Battery with 220 miles of range or 311 miles NEDC.

The ‘futuristic’ cord connector is not really the charging station… Large equipment in the corner of the parking lot to generate the required Six Phase power takes up much more footprint than indicated in the picture provided here.

Six phase power? Why would they need that?

Why do they need six phase power? Ask them. A former article left a pretty complete one-line diagram of how they’re doing it, and it is a six-phase (six wire) system.

But I’d assume the european power factor requirements (>.98) are easier to meet with 600 hz (720 in the states, if it ever gets here) – plus the ‘flywheel’ chokes are smaller as are their ripple currents.

I’d like to know what it’ll cost for home charging. Solar power may be worth a few panels? How much is the equipment? Estimated electric usage cost.
