Looking for input on range - Confused

[Tpup]

I have a 21 Taycan 4S with the PBP. I'm in the "charge to 80%" crowd so I have the car setup to do that. I plugged in last night with 53 miles remaining and 21% shown on the battery indicator. I charged to 80% and my ChargePoint charger showed that it added 107 miles. That would suggest that the range of my last charge is 107+53 or 160 miles (160/.8 would suggest total range to be 200 miles).

My range to empty after the charge shows 213 miles (213/.8=266 mi total range) which is consistent with my last several ranges at 80%. So my read that as my actual range is 25% lower than my indicated range (160 vs 213 ish).

Cars got 10K on it and shows 2.7 mi/kWh for the last 3 charges (after I put on 21" wheels).

What am I doing wrong here or do I have a problem?

Thanks in advance for any input. I'm relatively new to Taycan ownership.

I would recommend you keep a log of the range displayed after charging to 80%. I used my log to demonstrate to my dealer that I had lost 60 miles of range in one week. I eventually got a remanufactured battery installed.

I am not sure if I am following the logic here with everything looking normal to me based on what the car is reporting, which is what you need to go by and not what your charger is telling you. Specifically, having PB+ and 21-inch under the best ambient conditions (70F-90F) with city driving is expected to be in the 270 miles reported range by the car. Are you saying you are getting 25% less of actual miles in driving than the car is reporting - if that is the case, then there is a problem - because the car is pretty good at estimating the same route based on historical data.

I a have 2020 Taycan 4S with extended battery which at the moment is showing 220 miles range at 85% charge. When charging to 100% the range is 255 miles and both figures are pretty accurate when driving the actual miles.

The best way to demonstrate anything to the dealer is to get an OBD reader and check your SoH and battery cell health (Temp, Voltage, SoC). If any cell becomes an outlier, that is an indicator of upcoming Red Circle of death as only one cell has to bad for it to go into Red Circle.

1. Relax. Obsessing about range, when you own a fast sports car with the best road holding of any EV, is not healthy. Get out and have fun with your car.

2. Take a longer-term view. See how it goes over time. The range guess-o-meter could have been influenced by lots of things including driving style and weather.

3. Do a bit of planning and (except for a small number of specific journey types) you never need to care about range. As long you have 150 or so you can travel huge distances, only taking short recharge breaks periodically (although as you are in the US this is not quite so simple given the current state of charging infrastructure).

the guess-o-meter is easily mislead - and is based on recent consumption/driving habits - it is NOT an indication of battery health/capacity - but rather if you drove like you did the past 18 hours this is how far I estimate you can go…

my GT3 on a full tank of gas thinks it's can only drive 75 miles as I pull away from Laguna Seca after a day of flogging it on the track - that is laughably inaccurate, the Taycan's range on the dash is equally easy to mislead and equally laughable - ignore it

Trust the Porsche Navigation w/destination input - I've found it's battery @ destination estimate to be wildly accurate +/- 3% - if the porsche nav says you can get there - trust it…it's the ultimate arbiter of range because it knows both speed limits and elevation for a given route.

it's 99.9% unlikely your battery has any problems -you're just seeing the daily gyrations that can occur from using trivial and small data sets (daily driving habits across a range of conditions) to estimate longer term status - it's simply wrong and will always be wrong.

if you're a new EV owner these threads may help

Speed/acceleration has a much much bigger impact on range than most people realize…all you're seeing is that for short distance driving you're less efficient of a driver than you'd like to be

... I charged to 80% and my ChargePoint charger showed that it added 107 miles. ...

My range to empty after the charge shows 213 miles (213/.8=266 mi total range) which is consistent with my last several ranges at 80%. So my read that as my actual range is 25% lower than my indicated range (160 vs 213 ish).

I'm not sure how your ChargePoint EVSE could provide a number for miles added. It would know KWh sent to your car and unless you provided the ChargePoint software some consumption/efficiency metric it couldn't provide miles added.

Your car's displayed range to empty seems normal, and actually pretty good, and is probably fairly accurate for your driving style and conditions.

Added: My displayed range at 80% is 212 miles today. It varies by +/- 10 miles and pretty much matches what I get when driving.

Like the OP, I'm also in the 80% charge camp. Mine is also a recently acquired 21 4S with PBP and my car always reports 166 miles of range when I charge to 80%, give or take a few miles. I've always assumed that this is normal because I live on top of a big hill in San Francisco and most of my driving is in the city. The longest drive I've done is around 500 miles, on the very first day I got it, to bring it home. Didn't really think about the reported range then—took me two stops to get home.

Thanks for everyone's response; very helpful.

My big question is what range are people actually seeing on a 4s with 21" wheels and PBP?

My second dumb question is what conditions lead to better range? In my SUV I can get on the highway and set the cruse at 70 and get 24. I get 12 around town.

For those at the high end of the range how are you driving (% town vs % highway)?

Thanks again.

2.7m per kWh is pretty normal in my view implying about 225 miles

Electric cars tend to be more efficient at low speeds as drag through the air is the biggest factor affecting range especially as it increases exponentially with speed. Driving in traffic is also typically not an issue as most of the energy from stopping frequently goes back to the battery compared to an ICE car which has the engine running all the time and is converting momentum into heat in the brakes.

other factors that will affect range include
- extremes of temperature (impacting both how much energy can be extracted from the battery but also using power to heat interior of the car or heat or cool the battery)
- wheels (some are more aerodynamic than others and more tyre contact with road presumably also impacts rolling resistance)
- gradient (going up hill vs rollling down)

Driving in Scotland I typically average around 2.6m per KWh on a mixture of motorways and A roads. A couple of weekends ago I did my usual longish drive and averaged 3.2m per KWh - what was he difference? I decided to take it easy and it was a lovely fresh day with no need for either heating nor AC.

Chargepoint quote on miles is an estimate. In fact, it doesn't even have my particular trim (GTS wagon), so my estimate is off and is based on a Turbo sedan. Prior to a recent app change, I was only able to select a 2021 Turbo Sedan before the range software update ?

The best accuracy you have is your own math. Chargepoint is accurate in how much KW you charged, and you can do the math with your mileage between charges (car also tracks this).

I have a CT4 with 21" wheels. My trips almost always end up between 2.4 and 2.8 mi/kWH. On the highway when I average about 75-80 MPH I am always bang on 2.5 (2.5*83.7=209.25). CTs have more drag than sedans so you should do a little better than that. I get into the higher mi/kWH numbers when I run errands on surface streets.

what conditions lead to better range?

If you put a sample journey into A Better Roule Planner you can experiment with speed, weather, load, wind, etc and see what happens.

But my previous advice still stands: by all means learn, but don’t get obsessed and turn into a range bore. It is likely you have sufficient range.

That is very much dependent on how someone drives their car, plus of course outside temperatures, weather, type of tire. If it helps you at all, my 2023 Taycan Turbo CT (PB+ battery) shows 189 miles as I write this - 20" all-season tires, WA state weather, heavy right foot driver, bunch of short trips last few days. Couple of days ago I remember it showing over 200 miles at 85%, same tires. My Taycan's lifetime average consumption is 2.6 miles per KWh (over 550hrs driven).

My second dumb question is what conditions lead to better range? In my SUV I can get on the highway and set the cruse at 70 and get 24. I get 12 around town.

The slower you go (say down to 30mph) the farther the range. The more braking you do, the lesser the range too (regeneration is 100% efficient). Cold weather will lower your range. Rain/snow will also lower your range, as will climbing in elevation. You can in fact gain range when going down steep hills. too. Perhaps surprisingly, a lot of factors are the same as in an ICE car, except people in ICE cars don't obsess over range. As a point of reference. a Bugatti Veyron can empty its entire tank of gasoline in just 5 minutes of driving at its max speed. Your Taycan will also show less than a 100 miles on full charge if you track it well.
