Battery deterioration

[Saunders]

In a few months I'm looking to get my first Taycan and had initially been set on a Performance Plus 4S. But I've started to consider some standard battery 79kw that have a better specification within my budget, and I'm considering that the spec may be more important to me than battery range, as my commute is only 45 miles roundtrip with the ability to charge at home.

I'm led to believe the battery range is circa 30 miles less, so should be expecting somewhere between 200 - 250 mile range. But when looking, I noticed this advert that showed 134 miles at 81%? I'm aware of the advice to have a battery health check carried out before purchase, but wondered if is this an initial indication that the battery is losing life - or can it can it vary this much dependant on driving style/weather etc?

I get between 210 and 250 winter/summer reported on my CT4S which has the performance battery plus as standard.
That may well be about what to expect from the smaller battery in winter.

I would not worry too much about the shown milage as long as you get a battery health check. Most likely it's just the weather/recent driving etc. that causes the low range estimation. Mine currently shows 182 miles at 80% with the bigger battery (And that is a RWD) where the battery is healthy but with around 0C outside for the last week or so.

There is cases where the battery fails but that usually results in a drastic range reduction within a short timeframe. I don't recall having seen any batteries having enough normal degradation to really impact the range.

Which model year of car MY25 or earlier - my guess is the latter?

Appreciate the budget constraint and if range matters then the PB+ is a "must" as the standard battery may not be an ideal outcome. J1.2 (as you no doubt know) is larger (larger net usable) and so adds more range possibilities.

If buying privately be wary of the depreciation and if you don't have PB+ then already it won't be as desirable as one with (regardless of the options you spec - they lose value rapidly).

J1.1 PB+ in UK winter will get 205 miles reported range at 100% (170 - 175 @ 85%) - PB under same conditions and same wheel / tyre size will fair considerably worse as the above image appears to indicate.

If not buying new then it is a buyer's market and top of your list of options must be PB+ - you will regret it otherwise unless you like the idea of charging more regularly.

Yeah it was a 2020 model.

Initially I had only considered the PB+ as whilst most of my journey's would be 45 miles max a day, it would be nice to have the option of 200+ for the odd trip etc, plus appreciate it is more desirable come resale.

If you lived in Miami or somewhere where the ambient is always high then I'd be advising something different as the range from PB is impressively good and amazing with PB+ (300 on a good day).

I get between 210 and 250 winter/summer reported on my CT4S which has the performance battery plus as standard.

That's the range I get in my Turbo with the big battery. The 250 is for motorway driving at 70mph. I can squeeze 300 mile if I drive at 50 mph all the time.
I would therefore think you will be getting 10-15% less with the smaller battery if it was in good health.
....but..... with the weather we have had this week the range can be even less than 210 miles - ie putting the heating on an hour before the first trip in the morning to get rid of the thick layer of ice etc. I did a 20 mile round trip today and 20% of the battery power disappeared with temps between -8 and -4°C.
Get the bigger battery pack.

Personally the winter mileage drop would rule a standard battery out for me. While your daily commute is just 45 miles, you also need to account for pre-heating (deicing) on days like today - which used 5% of my bigger battery this morning alone and will likely use another 2-3% when I do it again in a minute to leave the office, so that's around 8% used today on pre-heating alone. My very short 3mile commute is getting about 0.9mi/kWh currently where it's so cold.

If you have home charging and don't mind charging most days then there's no issue, but it soon becomes tiresome having to charge often.

The OP's point is to find out realistic range for a PB battery original Taycan example that is in the budget. Let's look at the data and then anyone with PB battery on a RWD or 4S, give us some winter and summer ranges with a tire type.

Use case is a 45 mile roundtrip with ability to charge at home, so let's focus on that number.

PB battery is listed at net usable 71kWh when new, but we know we can use 72kWh as basis.
We know that 10% degradation is expected in the first 10k miles, so net usable is say 65kWh.
Then let's say for daily driving it is recommended to charge to 85%, so you start with 55kWh.
However, you do not want to bottom out too low, so let's shave another 5kWh for 50kWh daily use.

Again, I do not know PB battery consumption rates on a RWD or a 4S but in near 0C weather with full comfortable heating enabled, I can see worst case of 40kWh/100 miles, so that gives me 125 miles worst case on 50kWh in most battery care friendly SoC conditions. However, we know it is totally fine to charge up to 100% right before departure, but not ideal for daily.

Other things to consider for PB battery that it is lighter but has lower peak charging rate at DC chargers.

The baby battery has worked just fine for me. I have a 3-year old 2022 RWD. Its pretty cold here now and looking at the at the app it is showing 70% charge and 143 miles range - so a little over 200 miles at fully charged. Summer it’s more like 225. From what folks are saying seems like you might get 20 or 30 more miles with a PB+. So question is are there use cases where those extra miles mean you can avoid finding a public charger? … if not probably doesn’t make much difference. My two cents… but maybe I am talking my own book .

Range is the only thing some people talk about with EVs for some reason! Bores me to death.

My Ferrari 355 has a shorter range than my Taycan but pretty well nobody mentioned it in road tests of the time as far as I remember.
It has never been a particular problem, and my Taycan hasn't either and gets less as the charging network expands.

Having less weight will always be better for every aspect of a car and I expect range will almost never be a problem for most people but the blind obsession with range on the internet probably means by far the biggest problem with the standard battery is image and resale value, which is another sad reflection on the power of misinformation.

In my case, were my car fitted with the standard battery it would only have much influenced 2 holidays in 2 years yet being lighter the car would have been better to drive every day of those 2 years.

The other thing we don't know that much about yet is how to evaluate the battery life.
Traditionally we used milage to judge how worn out an IC engined car was, and it isn't a bad measure though a low mileage car which has done a lot of short journeys may well be as deteriorated as a well maintained high milage car.
With EVs, and certainly their batteries, it is by no means sure that mileage is a good way to evaluate deterioration.

I’m considering a Taycan 4S CT with PB+. Do you always get a battery status report when purchasing from an OPC ? Any advice before purchase ?

No you don't. But you can ask, as a deciding factor in the decision to buy it or not, and they will comply, or at least give you a SoH %.
