20KW charging

[Dr.Ericthedrill]

Dear All,
I am mostly using a 20/22 KW hour charger, is this bad for the battery?
I never use a 50KW charger and very very very occasionally use a 8KW charger.
Thank you for your advice.

No not bad per se but what onboard AC charger do you have - 11kW or 22kW?

Note from Porsche if you have the 22kW AC charger::

22kW on-board AC charger:​

Optional On-Board AC Charger to increase maximum charging power when charging with three-phase AC up to 22kW and to shorten the charging time.​

Please note that for single-phase charging (up to 7kW) the standard on-board charger is recommended.​

To increase the lifetime of the 22kW on-board charger, when charging from a single-phase power supply, it is recommended to limit maximum power to 25A (6kW).​

Thank you for your reply.
I live in a high rise building and I do not have a home charger as yet.
I charge at a local club I belong to where they have 22KW chargers that can be used for free.
I do have the 22KW on board charger in my car.

You have a 3 phase power supply in HK, like China and Europe. Nothing to worry about the on board charger.

You will have some battery degradation, but will mostly be due to aging, since you are somewhat limited in HK to drive many many miles, right?

Charging at your club with 22kW is an excellent charging solution. Wish my club (Xili) had free chargers!

That's perfect then and nothing to worry about.
