The EV explosion

At the moment, I only have 3KW of solar PV, 4KW of solar thermal and an 8KW wood burner that does space and water heating.
The solar PV is connected to a wall of 896 18650 cells (Samsung 26F - 2600mAH giving 10KWH connected as 14Series64Parallel, split across 4 boards). At the moment, the wall is charged within 4 hours of sunrise, and goes back on to grid power at midnight, when cheap rate electric starts. This charges the wall back up to 100%
It runs nearly everything in the house, apart from the range cooker (9KW electric) and a tumble dryer.
The lights, heating pumps, washing machine, CCTV, Telecoms, TV, Fridge/Freezer and car charger are all on the wall. Adding the Leaf would have got it up to 30+KWH, or enough for 4 days straight without any solar PV.
I can add the Leaf traction battery in using the on board 360V to 12V DC-DC converter, which charges the cars 12V battery and then run that through another external DC-DC 12V to 48V buck boost converter as a temporary measure.
