MyPace is reporting Estimated Energy 83.15kWh at 99% SOC. Is that about right?
How are you getting MyPace to give you estimated energy please?

It’s there, on the fourth line down. “Estimated energy”.

Thank you! Stupidest thing but I’d never opened MyPace when I wasn’t charging, doesn’t show up when you’re charging!

This value is the same Wattcat indicated energy in the battery, coming from Jaguar API.
Would be very interesting to have the same estimation but from ODB, monitoring the battery bms.
At the moment I know just Power Cruise Control, doing this job.
Any other ODB software for I-Pace?

PCC shows available kWh based on SOC but in my car it has been from 70-80kWh with full charge when WattCat shows 83-86kWh so I would trust too much of it.

If you take the optimized percentage in WattCat and multiply with 86kWh you get an estimate of the current fully charged capacity.

Exactly !!!
A couple of weeks ago I made the only reliable (IMHO) test to measure the stored energy, which is driving continuously till very low capacity.
I think that the most affordable indicator we got is the indicated average consumption from the i-pace. If we do some math we can estimate the used energy.
I drove for 409 km (even if I noticed a low error in the odometer, -2.5% so in reality I drove more km...) and started with a PCC full capacity of 77Kwh (SOH 91.5%, inaccurate IMHO)
Here the results (tested wattcat too).
My conclusion is that I trust more on Jag and Wattcat than on PCC.

Available Energy in PCC is always lower as the Wattcat shown figure.
But it is quite close at my car as the SoH is in between 97-98%.
I use the granny charger once a month having the car unlocked and the hazard lights on charging the car from 10% SoC to 100% SoC... it brings up SoH every time resulting in a higher available energy in PCC and Wattcat... you might ignore keeping the car unlocked and hazard lights, maybe it is just my personal thing, but using the granny charger is a good thing for the battery I would say.

Using the 10A charger (2KW) means around 48 hours from 10% to 100%.....
Do you have a faster granny charger ?? 😂


It’s very curious that PCC creator suggest me to only fast charge to let SOH value increase...

Hazard lights are taking more power when they're on than the granny charger provide :)
