Hi Peter,
I'm using OVO's EV plan, 5c discount from their off-peak rate for midnight to 5 am. Unfortunately I do around 120 km/day, so I must charge during the week. I setup the charging period for between midnight and 5am, the app I'm using will also draw from the Powerwall if it has sufficient charge, so that's costing nothing, but even when it doesn't, the rate is 13.55 c/kwh, subtract the solar input tarrif (I generally export more than the EV consumes) and I'm back to 5.55 c/kwh. I use about 16.5 kwh/day, so that's costing me less than $1 to drive to work and back in electricity, so not too bad. Of course you have to add the 2.2c/km that the Vic government charge to use the roads, so it comes to about $3.6 all in. Compared to an ICE vehicle at 10 l/100 km and $2.20/l, a whopping $26.40/day. The car will pay for itself in about 10-11 years at this rate. about the same turnaround for the 10 kw solar and battery system.
I'll do the maths and see if I should get the long range and do as you are doing, especially with the prospect of FBT free salary sacrifice in the offing.
Cheers
Stu
