I charged at the Mona Vale Library carpark Jolt charger again this morning - cool morning (15C) and after 25 minutes driving from Palm Beach. Definitely the battery heating sucked in a fair few of the “free” first 7 kW, but it did get going (up to 21kW or so) later in the session.
Something I noticed is the real-time kW from the charger is reported differently between the car (firmware 2022.12.3.2) and the app (iOS, version 4.8.1). I took the two photos below immediately after each other.
The app seems to show what is delivered to the car from the charger (21-22kW)…
…whereas the in-car display seems to show what is actually making it into the battery (10kW):
The other displayed values (km/hr rate, time remaining and kWh added) agree between the app and the car, but the current kW values look like power “used” vs “added” respectively. I wonder where 12kW are going, but I guess the heat pump plus front and back motor afterburners all doing battery heating could well add up that sort of number.
As I said above, by the time I got back to my car from doing my small grocery shop the battery was getting 21kW.
Interesting pattern in terms of what made it through to the battery over time during the charging session (from the Nikola app - I only have that and TeslaFi, I don’t use ScanMyTesla, sorry). You can see from about 20 minutes onwards the battery got pretty-much everything the charger could deliver:
Anyway, I got about 9kWh into the battery for $2 while I had a coffee and bought some stuff from Coles
