Solar Powered Ute

[mackoffgrid]

I am nothing if not slow

The solar Ute project is ticking along .... However I haven't installed the batteries yet.

1/3rd - ish of the cells are going to be fitted in between the radiator and the motor. Construction of the 3 tier aluminium box has taken some time. The rest is going under the rear tray. The parts for the rear box are being laser cut and folded - ordered, should have it soon.

I've been through at least 3 incarnations of the BMS, If I had settled on my first design I would have had them months ago, and at half the price. Instead I went for capacitive cell balancing and needed to redesign several times due to stm microcontroller availability.

Getting closer. Fitted the rear battery box. Sits neatly under the tray. A few more gusset plates and we can start loading batteries. The Rear Battery will carry a little over 2/3rd of the total cells.

The cells will sit in 2 levels. The second level floor will also make this battery "Tank" more rigid

The tank was fabricated by Laser cut - folded mid piece with welded ends.

There is a good thread on the Leaf DCDC converter.
