Battery Range

[Mason]

Hi

I’m new to the forum and would like other owners comments. Since new my 4S rarely does over 165 miles from a full charge, which is nowhere near the published figures.

on the Porsche app after 100% charge, I get an indicated 206 range, which plummet’s once in use.

the Porsche centre tells me the battery cells are operating normally and there is nothing they can do.

any feedback would be greatly received.

I get 240-260 from my CT4 - 2000 miles winter covered - switch to Range mode and see if that ups the result. It also depends on how hard you drive plus battery temp.
Pre heat the car switch to Range and see if that helps

Also, use recuperation (if breaks are already set and recup works).

Pre-heating and Range mode won't make a dramatic change to your range once on the road. The reported range will be higher but as soon as you start your journey your range will adjust and sometimes quite significantly.

CT has the Performance Battery Plus as standard so you have the 'biggest' battery available.

100% charge with an ambient outside temperature of around 12C should return 220 miles - before you start driving.

206 miles does seem on the low side but if Porsche have tested it and given it a clean bill of health then the situation gets a little trickier unfortunately.

How old is you car (mileage)? If relatively new it can take a wee while for the range to creep up (it will never be spectacular in UK climate) but 240 - 250 miles should be achievable in milder and warmer weather.

What settings did you typically have enabled in the car - specifically AC and cabin temp? This can be tweaked to extend range but if starting from 206 (max) then that won't increase (obviously) but can tease out additional miles (e.g. AC ECO / ECO Plus (not recommended), Range mode (potentially).

How much motorway driving do you do?

Sorry no silver bullet in this response but useful to have a bit more detail.

Thanks WINGE

The car has less than 1000 miles and pre conditioning only happens when on charge. AC is on auto with cabin temp set at 20 degrees.

Mixture of motorway and city, but mostly motorway.

Thx for the additional information.

Motorway driving is a killer - constant speed typically and if @ 70mph then range does suffer.

AC settings are good too. Using the heated seats and steering wheel can complement this and uses very little energy. Switching to Eco Plus would add another 15 miles (or so) on a journey - try experimenting with AC OFF, AC ECO & AC ECO PLUS without going anywhere to see what your range registers as - 206 should become something akin to 215+ Range mode would add more still (switches of 1 motor).

I think your car is still 'new' and so the range will improve for sure.

Newer owner (picked my car up in Nov) and, having taken my first extended trip in the car this past weekend, noticing that I get dramatic variances based on driving style, mode and ambient temperature. Car is averaging 2.6mi/kWh in total, to-date. So not that dissimilar to your average. Having said that, got 3.2mi/kWh on the 200 mile leg down (40 degree Fahrenheit outside; normal mode) vs. 3.6mi/kWh (60 degrees outside; primarily range mode) on the leg back up. Mostly freeway driving on both legs unlike my typical city driving. Obv. I didn't control for temperature and driving mode. Average speed 62mph on the way down and 42mph on the way back up due to pockets of traffic but consistently at 75-80 outside of those pockets.

I was pleasantly surprised by how it far exceeded Porsche estimates on range during the trip. In total, with the batter capacity remaining on the leg back up, the car would have provided 250 miles of range vs. the 200 mile OEM estimate. So definitely a case of YMMV.

Check you haven't got AC or heating accidentally switched on.

If diagnostic tests have been run and the vehicle has no electrical faults, then that can be ruled out.

Motorway driving can kill range for EVs. No different to the laws of physics with ICE vehicles, where driving at 70mph vs 60mph sees fuel consumption increase 10% because of wind resistance. We can make a similar estimation that driving at 70mph in an EV will reduce range by 5-10%.

It has also been very windy in the UK past two months.

Plus there is another factor for EVs: driving at higher speeds (>50mph) places more demand on the battery. That too decreases estimated range, while wind resistance increases.

21" rims will drop about 10% range.

220m is now reduced to 178 miles.

If you are heavy on the accelerator/drive an EV like an ICE car, that too can hammer range, where you need to go easy on the accelerator and also rely more on regen for braking, despite how tempting it is to drive a Taycan hard.

Let's say that reduces range 5%.

The cold reduces range. Let's call that 5%.

= 160 miles

Finally, your computer is estimating your range based on your driving style and it will round it down to prevent the driver being in a dangerous situation where they run out of charge. Even if you have 0 miles of range remaining, you likely have at least 10 miles left (add that to the above calc.) to find a charging point.

So your real range is probably about right, and the bigger factor behind poor range is majority of your driving is on the motorway.

I've recently been driving a luxurious Peugeot e208. Range should be 215 miles. I did a motorway trip the other weekend of 120 mile round trip. I had 190 mile range on the dash. By the time I got back home, I had 5 miles of range remaining. It wasn't pleasant as I thought I was going to run out of charge on the road; and I was anxiously checking my trip distance and range every minute as they danced around together.

I know we cannot compare the cheap components/battery of a Peugeot - who are known to have poor EV batteries - to a Porsche Taycan, which has a class-leading battery pack - but my point is motorway driving absolutely hammers range.

Should be as simple as useable battery capacity (about 84kWh from new on CT) multiplied by the average consumption. 84*2.4 = 201.6 (I'm assuming the 209 on the app isn't just based on the last journey but not sure, if it was it would say useable capacity about 87kWh).

Quite simply, if your efficiency isn't dropping below 2.4mi/kWh you should be seeing 200miles real world range (ignore the GoM). If you aren't able to do 200miles at a journey average of 2.4mi/kWh then it would seem to me you don't have the full 84kWh Available.

Edit:

Before I sold my iPace I did an export of some frequent, longer range journey legs with highish average speeds. Thought would be interesting to compare when got the Taycan as they have very similar accessible capacities. The only day the range would have been as low as you are saying was when I was at 1.92miles/kW (started with a 2C battery, heavy wind, rain over hilly Glasgow to Gretna, plenty of hard acceleration to heat battery and enjoy given knew was stopping in 82 miles).

Given the similar battery sizes, should have a decent feel for real world range based on average journey consumption. Journeys, with perhaps the exception of the 169 mile leg were in Normal, no nannying and some decent acceleration and AC etc. The iPace would auto drop slightly at speed in all modes so Eco was more a (slight) drive train and AC optimisation thing.

We're in the South West and last night, with temp about 5, we got 240 miles for 99%. The car then travelled 85 miles down onto Exmoor and ended that journey with a range of 157.

Lowest I've seen as a range is 225 when it's been minus temperatures. Car is a CT4 on 20 wheels, done nearly 4000 miles now

I find range may add 5 or so miles to the range, nothing that significant, though ACC eco does add maybe 10 - 15

Hi Batteredhaddock

Thanks for the reply, thats what i've been saying to Porsche as i get 165 - 175 miles which would mean i should see around 2.0 mil/KWH and my average is 2.4 Mil/KWH.

I'll try Porsche again but also try the other suggestions in the thread and monitor during the warmer weather.

Regards

Steve

It's important to understand how batteries and BEVs work.
The actual state of charge (SOC) the battery as well as the range are estimates, based on several assumptions an algorithm has to make. Porsche's choice is very defensive/ pessimistic (i.e., I always arrive at my destination with more SOC than estimated).

However, the range of an EV depends on many, many factors:
* temperature
* rain
* …

The biggest issue, however, is that driving behavior and speed affect the range much more than in an ICE car and that's not really predictable by the algorithm.

Yeah, something doesn't seem right at all. Think all the stuff about weather , driving style should be irrelevant as they just affect the average mi/KWh (i.e. your comment on not seeing 2.0 which you might on a Eunice day). Either your reading of 2.4miles/kWh is erroneous, or you aren't getting the correct capacity of the battery (for a new vehicle) to be that far off.

Also it should get better over time. My CT4 started with about 200 miles at 100% but now it has risen to about 255 miles on full charge. What are your driving habits?

OP lives in UK so this time of year will be doing well to get 220 - 225 on a full charge. On a 350kW charger which toasts the battery it will no doubt report 250 odds but 2 mins of driving it will cool and settle down to around 225. Charging at home will never reach the dizzy heights of summer charging range.
