Porsche announced that the Taycan will be able to achieve 60 miles of charge in just four minutes (at peak)!

Porsche's electric pitch: This car will recharge super fast

Zero-to-60 times are shorthand for what anybody buying a Porsche is supposed to care about. But with the all-electric Taycan due out later this year, Porsche executives are talking up a less-exhilarating metric: getting to 60 miles of charge.

Stepping into the world of electric cars is making even the most hallowed performance brands rethink how they market their vehicles, and Porsche is no exception.

At peak, the Taycan will be able to add more than 60 miles of charge in four minutes, thanks to an 800-volt battery that can absorb fast-charging rates of up to 350 kilowatts. That’s quicker than Tesla owners can achieve at the company’s 120-kilowatt supercharging stations, which can bring batteries to about an 80 percent charge in roughly 30 minutes.

“Getting into a car and doing 0-to-60 mph in less than three seconds -- can you really differentiate yourself if you do it in 2.8 seconds, and the other can do it in 2.7?," said Klaus Zellmer, the head of Porsche Cars North America. “There are other factors that will gain importance, such as charging time.”

That may sound like blasphemy to some Porsche enthusiasts.

Selling point

But charging times will be a key selling point for automakers trying to coax consumers into overcoming their fear of being stranded with a dead battery. Porsche’s new four-door sedan is part of a pack of luxury electric vehicles, along with Audi’s E-Tron and Jaguar’s I-Pace, that are looking to capture some of Tesla Inc.’s industry-defying magic. Sales of EVs made up just 1.1 percent of new-car sales in the U.S. last year, according to researcher LMC Automotive, and Tesla accounted for most of that.

Charging infrastructure is a new perk for would-be buyers. Through a partnership with Electrify America, the charging-network company borne from Volkswagen Group's diesel-emissions scandal, Taycan owners will get three years of free charging at stations that’ll have a minimum of two 350 kilowatt chargers per site.

While Electrify America announced Friday that it was shutting down its fast chargers to investigate a potential safety issue involving a supplier’s liquid-cooled cables, Porsche said in an emailed statement that it's confident the issue will be resolved before the launch of the Taycan later this year. And in addition to the network of 300 highway fast-charging stations that are going to be either installed or under construction by July 1, another 120 Porsche dealerships will offer fast charging by early 2020.

Building long-distance charging infrastructure may not be entirely rational, since about 90 percent of electric-vehicle charging happens at home. But that hasn’t stopped automakers from touting their charging offerings. Audi is giving away 1,000 free kilowatt hours with Electrify America for anyone buying a new E-Tron. General Motors' Chevrolet Bolt EV comes with a card for ChargePoint stations, though the driver has to foot the bill.

Pay-for-use

Tesla is also moving toward a pay-for-use model after previously offering 400 kilowatt hours a year of free fast charging on its proprietary network. CEO Elon Musk has promised upgrades to its Supercharger network early this year.

This is a new role for automakers who have no real interest in today’s network of gas stations that provide fuel for millions of internal combustion cars.

“They really don’t care where you charge, but they do care that you feel comfortable that you know you can charge so you’ll buy the car,” said Brett Smith, director of propulsion technology and energy infrastructure at the nonprofit Center for Automotive Research. “For that to happen, the car companies have to get involved.”

Having long-distance charging is even less relevant for Porsche owners, Zellmer said, since most will own multiple cars and could take another out of the garage if they’re worried about needing to plug in. Still, he said, Porsche has to do it to “comfort” potential buyers.

Driven by regulatory mandates and a profound sense of existential anxiety over Tesla’s market capitalization, automakers are pouring billions into the battery-powered cars. Porsche will spend 6 billion euros ($6.8 billion) by 2022 on electrification and has said more than half its line up will have a plug by 2025.

Porsche hasn’t disclosed pricing for the Taycan, but it’s clearly gunning for the Tesla Model S, which starts at $94,000. Teslas will no longer be eligible for U.S. tax credits after this year, whereas Porsche has a long way to go before worrying about the U.S. cap of 200,000 electric-vehicle sales that triggers a ratcheting down of the incentive. The company sold 57,202 vehicles in 2018.

Taycan vs. Tesla

As for old-fashioned specs, the Taycan is expected to have a total system output of more than 600 horsepower and will accelerate to 62 mph in faster than 3.5 seconds. It can go about 310 miles before it runs out of juice, a bit short of the 335-mile range for the base Model S.

Porsche is feeling confident, boosting global production capacity for the Taycan to 40,000 from an original 20,000 units. The company says it’s responding to strong demand.

Zellmer won’t say how many people in the U.S. have coughed up the $2,500 refundable deposit for the Taycan, but he happily mentions that two-thirds aren’t existing Porsche owners. Among those, he says Tesla is the most common brand.

Marc Cohen, who owns a Porsche dealership in Towson, Md., says he has 25 or 30 names on his waiting list. They’re a mix of Porsche owners and general sports-car enthusiasts, rather than EV evangelists hoping to save the planet.

“None of the ones I know are Tesla owners or actual EV kind of people,” he said. “These people are luxury owners that understand that it’s the next wave of tech and what’s coming, so they’re just getting in line.”

Gonna be awesome when the Electrify America charging station network is fully built out to get that 60 mile - 4 minute charge. Will be interesting to see how long it takes to build out 300 highway fast charging stations though.

Smart of Porsche to focus on charging times and addressing range anxiety. Won't be easy to beat Tesla's 0-60 numbers, and really it's only for bragging rights like Zellmer says. In real world, anything sub 3 seconds is splitting hairs. It's all nausea inducing :)

One need to be careful about amount of charge provided over time - LiON batteries can only be filled at a maximum rate when the are close to fully discharged. All fast charging capable EVs delivered to date taper the charge rate as the battery fills up. I’m confident the Taycan and other Prosche/Audi 800 volt DC fast charge cars will charge at this rate or higher if they are close to empty - however if one pulls in to a fast charger at say 60% charge I’m fairly confident the charge rate will be significantly less.

I’ve owned EV’s for over 7 years and used virtually all the fast charging systems - the basic rule of thumb is:

You can get half the remaining charge in 20 minutes

Example pull in at 10%

1. Remaining charge is 90% - that means you’ll get 45% “back/charged” in the next 20 minutes - battery is now at 55%
2. From 55% remaining charge is 45% - that means you’ll get 22.5% in the next 20 minutes - battery is now at 77%
3. From 77% remaining charge is 23% - that means you’ll get 11.5% in the next 20 minutes - battery is now at 88.5% call it 90%

The last 10% of charging a Tesla P100D battery (about 10 kWh) can take over 40 minutes and the fast charging rates actually drop to being slower than L2 rates once the battery is at like 95-97% full (at home when I charge on my garage L2 chargers the charge rate also tapers after about 95% - at 98% the charge rate is about 2,000 watts or less for that last bit of “full”)

That means to charge from 10% to 90% took one hour - this matches approximate Tesla Supercharging charactertics pretty closely to observed behavior. And while not 100% mathematically accurate - it’s a useful tool for estimating fast charging rates from a given battery SOC percentage - it’s proven highly accurate in my 7 years of road tripping and works for Nissan Leaf’s, Bolts, and Tesla

The need to taper the charge rate is a universal electro-chemical characteristic of all LiON batteries, so I and the rest of the engineering community would be very very surprised if Porsche/Audi don’t conform to these chemical/physical requirements - there is no magic here.

The only question is how does Porsche’s 800 volt system change the equation - my guess is that it will change the 20 minute number to about 12 minutes - I.e.you can get 1/2 the remaining charge in about 12 minutes...But that would only be for a 350 kw charger which will be top teir - most CCS DC fast chargers in the US are 50 kW or 150 kW chargers - so there is NO hope of 60 miles range in 4 minutes from those chargers

I’m excited to see what’s actually going to happen in this space.

Porsche has said the car is 310 miles on a 90 kW battery - that means they are estimating 3.4 miles / kWh - that’s in line with a Tesla Model S so that makes since.

Therefore 60 miles range is: 60 / 3.4 = 17.64 kWh required to go 60 miles

17.64 kWh / 4 min = 4.4 kWh / min or 264 kW charge rate - well within the the 350 kW spec for the 800 volt system - but faster than a 150 kW or 50 kW DC Fast charger can provide.

310 miles / 60 miles = 5.166 - so you can get 60 miles in about 4 min - and if you do that 5.16 times you’ll fill the 310 mile battery - 4 * 5 = 20 minutes
310 / 2 = 155 miles is 50% charge
155 / 60 = 2.5 times = 4 min * 2.5 = 10 minutes to 50% charge capacity @ 60 miles in 4 minutes charge rate

I’ll stand by my rule of thumb estimate of 50% of remaining charge in 12 minutes
0-50% - 12 minutes
50%-75% - 12 minutes
75%-87% - 12 minutes
87-95% - 12 minutes

So my estimate is that to nearly fill a Taycan at a 800 volt system from 0% to about 95% will take about 48 minutes
But you can get to 80% charge in about 30 minutes - which is really very very good - 80% in 25 minutes is very very fast - 0-50% in about 12 minutes would be awesome (on a summer 2018 trip with my Tesla I got 8-50% in 12 minutes on a 120 kw super charger - I’m confident the 50% mark on a 350 kw charger will be 12 minutes or less - woot!)

We’ll see how my estimates compare to real world when we can all drive one :)

I’m pretty excited about this ultra fast charging too. My Tesla has been great for road trips but on really long ones that take all day, the repetitive 40+ minute stops get a little too tiresome.

As for the Taycan, I am looking forward to seeing the final product. I do have my doubts on the 300 mile range though. I don’t think it’s an official figure from Porsche, it was probably just a translation of the 500 km estimate, which is most likely based on the very optimistic NEDC cycle (even WLTP is more optimistic than the EPA cycle).

If the battery pack is about 90kWh total, at least 5kWh of the pack will be reserved for anti-bricking protection. So you’re down to 85kWh at most. I estimate 3 miles per kWh of efficiency, so we’re probably looking closer to 250 miles of range rather than 300.

But I can only time will tell. I still think 250 miles would be enough, as long as the 350kW infrastructure is well established and strategically placed along most routes.

A lot
daveo4ev, that's also my experience with charging a 360V battery.
One major difference is the Taycan's 800V architecture.
That'll give it twice the charging speed while the current stays the same (P=UxI)
So, I'm pretty confident that these chargetimes will be shorter but in the end, like you said, it'll drop when passed 70-80%.
But then again, I'm not in a hurry when I'm doing long trips anyway.

Grtz Dee.
