Charging break in?

[Ryun43]

Kind of an odd question ..Just picked up my new Turbo S after driving my 2020 turbo S for 18 months or so.
Car is great and everything is working smoothly.

Interestingly enough my chargepoint home flex that's on a 50amp breaker would charge my previous 2020 at 9.6ish Kwh (both pre and post software update). My new one is only doing 8.5 ish. I've recent the chargepoint and it is still in the 8s. Not a big deal or even an inconvenience...more of a curiosity.

I plugged into work today where I regularly got 6.6 and now its pulling 5.6.

Makes me wonder if the car charger is dialing it back either as a software change or something as part of a mileage based battery break-in. it doesn't affect how I use the car, just odd its almost exactly 1kwh on each charger.

I did DC charge on the road trip back from Atlanta. I pulled 243 to about 70% on a 350kwh and later 173 on a 150kwh so doesn't seem to be holding back on dc.

Any guesses?

Just to be entirely clear you are (and were) reading the charge 'at the car' correct i.e. on your lower screen?

My ChargePoint HomeFlex is hardwired (60Amp) and whilst it can deliver 11+ I never see more than 10.5 or so at the car. Similarly I'd expect with max 9.6-.8 output from a 50 amp setup to be reduced at the car due to obvious 'losses/inefficiencies' of transfer through hose etc.

8.5 admittedly a little low but possibly not that far off what you'd expect?

I wonder if you have that battery saving feature for DC charging on could it in some way be throttling the AC charge also - seems highly improbable but might be worth a check?

Yes both times I was reading at the car. For about a year my 20 turbo S pulled 9.6 off the same system. I made sure the settings on the EVSE hadn't changed.

Its more trivial than anything and I didn't think that much about it but when the charger at work was exactly one kwh lower that with my old car, I thought the car might been dialing it back.

The battery saving feature is turned off so don't think that's it
