For sure (from LG Chem website):
Did anyone do a CAN bus scan when battery shows 100%, if so what are the cell voltages? Taycan cell nominal voltage is 3.65V, which would suggest that its 100% voltage would be 4.2V.
It's adjusted based on a lot more things than just current SoC. Other factors that I'm sure are considered is current battery temperature, battery age, battery history, motor and inverter temps, probably other factors too.
Yes, I’m sure there are other factors. I was just commenting on limiting based on capacity.
A decade of driving Model S's. Always charged to 90% every time in the garage (regardless of SoC when coming to the garage), 98% for longer trips (don't like 100% because it disabled regen, makes the car drive different) - minimal battery degradation on all 4 of my Model S, the oldest being 7.5 years old. Plan to do the same to the Taycan, maybe 85% instead of 90% if that is what Porsche UI suggests as upper daily range (UI should always be more up to date than any user manuals). Keeping it plugged in just makes sense as it gives the car a choice to charge or use shore power if it needs to.
Fast charging does degrade the battery, that is a fact. There is a rumored spare capacity in the Taycan batteries (it charges to lower SoC at first, will try to confirm one Porsche manages to build and deliver one for me). Why would they let you? Because you need it on long distance trips. Does it degrade the battery faster? Sure it does, as does using launch control mode. Does Porsche still warranty the battery even if you charge at 250KW and lanuch every day? Of course they do, but notice that they don't guarantee 100% of the original capacity. I have not found the actual percentage, but Tesla for example only warranties 70% of original capacity in 8 year or 100K miles. So if a 400 mile range Tesla degrade 280miles, it's still not covered under warranty (279 qualifies you for warranty coverage). I suspect Taycan is the same.
11KW is not fast charging. Minimum DC charging is 50KW, and the charging rate which starts to do damage is usually considered 1C (i.e. rate which would charge the battery in 1hr), so for a Taycan, ~97KW. As a side note, I've been charging one of my Model S at 80A and another at 48A for years, minimal degradation.
That is my plan once the Taycan gets here (current TYD estimate February 2023). For trips I plan to do 98% since that keeps regen enabled, unless it's winter then 100% on trips since regen is limited by low temps of the battery anyways.
Honestly, who cares. You can ask for battery health when buying used, or just scan it yourself using a $50 worth of hardware and apps. Warranty still applies regardless if you keep it at 50% and never drive it, or you drive is 90K miles and charge to 100% using DC charging every day. On a Tesla rated range at 100% is a good indicator, not sure if there is an equivalent on a Taycan, but you can scan it using CAN bus (which you can do on Tesla but it's more complicated than just plugging in an adapter to OBDII port).
Oh no Dave! ? How could you not triple check whether your post was correct (prime numbers under a 100 are super google'able)?
Cudos for correcting it. ?
Rubbish! Only Porsche EVSE's pre-condition the electrons to be ideally aligned in orientation and spin to provide the lowest battery degradation, smoothest and most optimal power delivery!
The point is the car is advertised and sold with a stated range at 100%. A petrol car is also sold with a stated range calculated by tank size. If an electric car should only be charged to 80%, then that should be the advertised range.
Agreed, the equivalent would be going to the gas station and filling up everyday.
I don't think the state of fullness (or emptiness) is actually mentioned - we are simply given a fairly fictitious WLTP figure for range which none of us can match.
