Hi Trev
AS Bob said, nice power house.
I have a question regarding the batteries you took out of the Hilux.
You wrote that they may have been damaged by too deep a discharge when range testing.
Is there also a possibility they were damaged when you hooked the generator up to it when you took the trip to the EV show? In that thread you wrote that you added ice to get the pack down to a decent temperature.
If so, would it be reasonable to consider that excessive temperature is the reason for early failure of some of the cells.
I am thinking of building an EV ute/wagon similar to yours and the use of an external generator would be extremely advantages at times.
So my question is, does the gen set power need to run through the batteries or can it be used directly by the electric motor (after passing through a conditioner of some sort).
I am thinking of something like a house system,
eg solar panels - inverter, power to load (household) then excess either to grid or batteries.
EV with aux unit, gen set - regulator/conditioner - motor, excess to batteries.
How difficult would this be, and have you considered it?
