e-Hybrid Battery condition

[GJH_987]

Hi, I'm considering a 2015/16 Cayenne eHybrid. But with Porsche only providing a 7year warranty on the batteries I wondered if there was a way of confirming what the condition of the batteries are. Bit like on your phone where you can see Battery Health. My phone currently says Maximum Capacity is 89% so it's lost 11% in a 2years. I'd like to know the condition of the Batteries in the car before I purchase one.


Also can anyone comment on the charger / charging station situation? Do you need a specific type? I'd be charging from home mainly as I work from home and do short journeys.

Hi ghj,
I have a 2015 hybrid aswell. I'm pretty sure that a Porsche service center can assess the battery, probably not much help I know.
Although I imagine anyone who has a piwis and knows about the hybrid could do the same.
As for chargers you need a type 2, 7kw charger. The 7KW on board charger was an optional extra so look for one that has it. The standard is a 3.5kw so half the charge speed. I fitted a project ev charger, looks good and is very cheap.

This a great question. The battery *must* know this, even just a count of the number of charge/discharge cycles would be a good indicator (this is a similar idea to looking at the Wear Level Count on an SSD via SMART if you know tech). I asked Porsche if this was possible, but got a no / don't know answer. I suggest if someone with a Hybrid can find some stats on the battery via regular OBD (not piwis) then that would be very useful for a purchaser or owner to know!

I looked at getting a Hybrid, but IMO the battery replacement cost is not being factored into the 2nd hand price and it seems to be £10k. Without the above info you could just assume it lasts something like 10y / 100k and factor in an additional pro-rata cost of say £1k per year of age.
