Porsche Reveals Battery Secrets That Make The Taycan Go Further And Charge Faster

A lighter and more energy-dense battery makes the Taycan a mile muncher that also gulps electrons really fast.

• Porsche usually under-promises and over-delivers when it comes to the driving range of its electric vehicles.
• The Taycan offers impressive real-world range and is among the fastest-charging EVs in the U.S.
• After issues on early model year Taycan batteries, the latest version packs some clever engineering.

If you’re a driving enthusiast and an electric vehicle-lover, there are few cars out there that match the panache of a Porsche Taycan. In addition to being one of the best driving EVs, the sedan also consistently outperforms its own EPA range estimates in independent tests and is one of the fastest-charging vehicles outside of China.

For model year 2025, Porsche gave the Taycan a huge upgrade with more range and faster charging. Porsche attributed those improvements to a larger battery and efficiency gains, but it has now spilled some of the secrets as to how it made one of the nicest EVs out there even better.

For starters, the Taycan’s range increased from a maximum of 246 miles for model year 2024 to more than 300 miles for the current model year. Its peak charging rate also increased from 270 kilowatts to 320 kW, reducing the 10-80% charging time by roughly 3.5 minutes when plugged into a fast enough DC fast charger. Behind the scenes, Porsche made a raft of changes to make all of that possible.

The automaker said in a press release on Tuesday that it had improved the Taycan’s thermal management. The cell modules now use passive cooling, which is basically cooling that doesn’t rely on extra pumps or moving parts. Porsche also redesigned the cooling plate that can pull heat away much faster, from 6 kilowatts before to 10 kW now. That means the battery can handle high temperatures more reliably without overheating.

To boost charging speeds, Porsche added new bus bars—thick metal strips that move current through the pack—allowing more electricity to flow at once. As a result, the 10-80% fast-charging time dropped from 21.5 minutes to 18 minutes. The minimum battery temperature for fast charging also fell from 77 degrees Fahrenheit (25 degrees Celsius) to 59F (15C), which means drivers in colder regions can start fast charging sooner and save a few extra minutes while the battery preconditions.

That’s not it. In the 2025 Taycan, the gross battery capacity increased from 93.4 kilowatt-hours to 105 kWh for the Performance Battery Plus. Despite the increase in capacity, the weight of the pack actually dropped from 1,397 pounds (634 kilograms) to 1,377 pounds (625 kg). That’s generally the direction automakers and battery companies are headed in, trying to cram more energy into smaller batteries with innovations in cell chemistry and packaging.

Still, Porsche’s battery journey has not been smooth. Last year, Porsche recalled more than 27,000 Taycans because of a manufacturing issue at LG Energy Solution’s Poland factory, which could increase the risk of internal short circuits. At the time, owners of the affected vehicles were advised to limit charging to 80% and eventually got free replacements.

Porsche said more work went into improving the reliability and durability of its batteries. Even though its customers only fast charge only about 15% of the time, the carmaker conducted stress tests in 50% of all charging cycles, in temperatures up to 100C (212F) at simulated distances up to 300,000 kilometers (186,000 miles). It also conducted one-meter water immersion tests as well as violent side-impact tests, which the automaker claims did not result in any battery deformation.

The real-world results of all this battery engineering are pretty impressive. The base rear-wheel-drive Taycan with the 105 kWh Performance Battery Plus went 367 miles in Out Of Spec’s 70 miles per hour highway range test, beating its 318-mile EPA estimate. And in InsideEVs' charging test early this year, the Taycan Cross Turismo went from 15-70% in just 12 minutes, holding charging rates of over 200 kilowatts for most of the time.

Summary-
Larger battery, thicker bus bars and better cooling equals more range and faster charging. They also allow for faster charging in cooler temps.

I do wonder if that faster charging comes at a price of longevity but we shall see. Even if it suffers faster degradation….. it’s still a bigger battery to start off with.

The thing I love about this article it shows that Porsche is still innovating with the goal of having a premium EV offering.

A few months ago, we were hearing that dealers in Atlanta were telling the attendees of a track day that there would be no more EV’s. I thought that didn’t make any sense whatsoever given all the announcements about the Cayenne EV but now I’m certain of that.

I believe the tech is more advanced on the Cayenne EV leaving both the Macan EV and Taycan behind.

Battery tech / invertor / motors, porsche has been pretty much in close proximity to what's the best in the market - mass produced, ever since 2019.

The battery fiasco on j1.1 is due to LG cutting corners for their EU manufacturing lines, during their fast expansion - which makes it even more insane that porsche didn't sue them, when almost all other ev car brands using them did sue them or reached a public agreement.

The battery with a much more robust cooling, pushing 400 to 350kw up to 50% is on par with most premium chinese EVs that don't use dual charging (2 charging connections at once).
The battery chemistry itself is also pretty much best you can get bar solid state.

Oil cooling the rear motor of the turbo model is straight from formula E, so as on the edge of tech as you can be.

The wireless charging, while a gimmick, is also cutting edge tech.

Sadly, the software is very much same old buggy shit. Seems to be running a newer version of the Macan android based pcm, with all the bugs too, based on early review.
Unlike the Macan EV, the PCM hardware is very much a bad joke, putting a under powered CPU in a 200k car to save 50$ per car is a horrid joke. You can see it lagging in the reveal reviews, literately working at a 5-12hz refresh rate.

Mobile phone syndrome - next year's will be better....

Given the EU decision to not ban ICE is another nail in the EV experiment coffin add to that a charge per mile for EVs in UK, going electric makes little or no sense.

They are very much still effectively banning ICE. They changed the fleet target from 100% to 90% Co2 reduction, this means you will have everything electric and maybe 1 ICE sports car model at an absolutely insane price (maybe e.g. a GT3RS), because they will have to sell 9 EV's for every 1 ICE sold.

You can't really reduce Co2 anymore through efficiency gains.

Tell me, how is it looking for Porsche at the moment? More like 0,1 EV for every ICE sold. So nothing really changes. All this does is allow some exemption for supercar makers for the very rich.

Details aren't clear and before the latest press reports niche low volume cars such as you mention were always going to be available.

On the back of the latest reports I expect more ICE models will prevail than was anticipated. Case in point is the forthcoming new Pirsche SUV due around 2028 and the ongoing development of other existing non EV models in the lineup well beyond 2035.

Europe isn't ready for mass electrification which was the plan when these rules were first set some years ago. Over time they have and continue to be eroded as we all guessed they would.

Many plans will change on the back of this and new EV model plans deferred.

From the consumers perspective if the rules are being softened and there is no motivation to purchase electric only then logically their purchase decision will be a lot more flexible and likely side with ICE / hybrid for as long as possible.

The details are very clear (at least to me, since I am in the auto industry). There was supposed to be 100% fleet CO2 reduction by 2035 (effectively banning ICE), now there is 90% CO2 reduction by 2035, meaning at least 9 EV per each ICE sold.

Also the new emissions standards (Euro 7, 2026-), mandate using Lambda 1 all the time. This means lower outputs per unit of displacement and increased CO2 emissions (albeit lower NOx and HC) for the same power output, as larger displacement needs to be used. So this is a double whammy.

It is useful to read beyond the sensationalist headlines - a skill you inadvertently also pick up when trading the capital markets.

As for niche cars - the exemption was for very small volume production, a GT3RS is not it, however it is possible to just not register the GT3RS on the road and keep it for the track only.

Time will tell.

For Porsche to be successful in the long term with its EV products, they have to figure out how to deliver value that isn’t framed in the context of other mass market EVs (range, charging speeds, tech, etc).

A 911 was never benchmarked against a Honda Civic or Mazda Miata for fuel efficiency or other more mainstream value drivers. The differences between the two were clear and Porsche led the way. I hope they figure it out because my preference would be to daily a Porsche EV forever and keep an ICE car for fun. This may fall apart if the high priced Porsche EVs are just playing catch up with mainstream industry benchmarks.

Time will tell.

Yeah, it’s not much different in the US.

Ideology and reality are not mixing well in this arena. The 2035 date was never realistic when technology, economics, sociology, geography and physics came into play.

There are some realities that just don’t make 100% possible.

Such as-
Affordability- they still cost more and not everyone could afford them.

Charging- significant amounts of the population don’t have the ability to charge at home. We also have places like Wyoming where only 500,000 live in the entire state and would have to travel long distances making charging infrastructure extremely cost prohibitive per capita.

In case of emergency- With mass evacuations for hurricanes (Florida), the amount of charging infrastructure required to evacuate millions of people hundreds of miles would be astronomically expensive- meaning those DC charging stations would be idle 99% of the time, except for that once a year mass evacuation time.

These are just a small number of the hurdles, but there are many more preventing 100% adoption

Could we pull off 100% anywhere? Yes- in larger cities where they could control the infrastructure and long distance driving wouldn’t be as much of a concern.

I think this is right. To me the question is how Porsche can succeed in the EV space. Is it by converting existing Porsche ICE owners or bringing in new outside the brand EV enthusiasts? I fall into the later category.

I’m the latter as well.

The answer is that they are, and have to do both.

Porsche style and driving dynamics with the daily drivability of an EV sounds like a win for both groups.

Honestly not much different than what happened when they started making sedans and then SUVs.
