My scanner says 100% at 21.6k km and a few months shy of two years since manufacture. Not that it means much since SOH numbers come from an unknowable black box.

Presumably as accurate as the data it is reading from the car.

Still raining, roads still cut. Grid power hasn't been interrupted fortunately (poco sent a warning out yesterday to expect it) but even so I've been making use of the V2L, charging the car up during the free energy period 12-2PM each day and discharging to the home battery to supplement the...

It now looks like we have hit that period where the rain is just going to be non-stop. The bridge across the river has now gone under and is closed and several areas are now isolated and will be for quite some time. I expect later today we'll be cut off from the main highway. And yet the worst...

The unit next off the block here most likely to be V2H/G capable/certified is the Sigenergy DC charger. It's not a standalone unit, needs to be part of the Sigenergy stack (inverter + battery) and costs ~A$7k for the 12.5 kW unit and A$8.5k for the 25 kW unit. It would also require the car...

Turned out I only drained 2.4 kWh from the drive battery. Weather was weird, just as Coulomb described: Which meant that we actually got a bit more from solar PV that I thought. Anyway, with the car's help the home battery was fully charged by 3:45 PM and the car is still at 89.3% SOC, so I'll...

At end of the free period the car got to 93% and the home battery got to ~ 90% so now I'm sending some of the car's excess charge back into the home battery via V2L and a charger. Set the car's discharge limit to 80% SOC but it won't need that much. Charging at ~1.6 kW into the home battery...

Sucking down the juice in prep:

We are about to hit the 12-2 PM free energy period so will be charging up the home and car batteries as much as I can. Home battery likely won't get to full charge today because of poor solar output (it didn't get there yesterday either) so I may dump some back from the car into it later...

Alfred is tracking back north again, these systems are so unpredictable... We are a fair way south and outside the expected danger zone but expect a LOT of rain with moderate to major flooding over the coming days. Hope all our northern friends stay safe.

Infinite miles/kWh. Dorrigo to Thora.

Updated with February data:

This is our long term economy and normalised range estimate since I started capturing the data with Home Assistant: We live northern NSW so a mild to hot climate at times. Spikes in economy rate will be due to long highway journeys up/down the Pacific Motorway. Overall the general trend has...

Not sure about over there but here the 51 kWh LFP MG4 has a max DC charge rate of 88 kW.
