[FAQ] - Question: I'm a new EV/Macan owner - I'm stressed about the battery…

[daveo4EV]

Question: what can I do to maximize my battery's life even though I likely won't keep the car long enough for it to matter?

TLDR; short answer - there is nothing _YOU_ can do to the battery…there is thousands of lines of software running in your vehicle to manage the battery - if anything happens to your battery is was very very unlikely to be anything _YOU_ did to it…

this question keeps coming up - and it's been answered before…I'm pleased with how this post has aged - so I thought I'd share it here - post #4 from this thread in the Taycan forum…shared here for your insomnia fix or enjoyment - your choice!!

Porsche and it's battery management software is in control - you are not - even though you are plugging the car in - Porsche's in vehicle on board Battery-Management-System/Software (BMS) is doing all the heavy lifting - there is nothing _YOU_ can do to the battery - what ever is going to happen is going to happen - it's not anything you did!!!

used Tesla - 180k+ miles - still has 90% battery capacity left after over 1000 charging cycles…

as long as you don't have a warranty issue the battery is not the problem.

I've driven a Etron55 from 2019 before my Macan 2025. Battery capacity about 90% after 200k+ km

The one thing you can do is to set the "max charge" to 80%, which will do the most to preserve the battery for longevity. At the expense of having to plan ahead if you're going to want to drive 280 miles instead of 220 (or whatever your conversion/speed factor is.)
This does make the battery last longer, but from what I know about the chemistry, it's 10-20% of longevity (20% range loss happens at 12 years instead of at 10 years?)
I haven't seen qualified aging curves for the cells used in these vehicles, so the specifics aren't 100% clear, but it's not a huge difference, no matter what specific cell it is.

What I do: Plug it in every evening, get a 80% full car every morning, and never worry or wait for charging (or having to do detours to a gas station) because I don't drive more than 200 miles per day.
