Started the fabrication of the front battery box mountings this weekend my choice of steel was the same thing I used for the engine mounts
40mm x 20mm 2.5mm thick steel box section mainly because I've still got about 5m of it as with the engine mounts I've reinforced it where the mounting bolts go this time with steel tube welded in to stop it crushing when the bolts are tightened up
and here it is tacked in place
I couldn't go any further as I've run out of gas so probably won't get any more welding done until Tuesday so I went back to the charger
this is the bottom half of the top housing from the Nissan Leaf stack which originally housed the Leaf charger and DC to DC converter which I am not using for several reasons including the fact that it wouldn't fit under the bonnet but it will just using the lower half of the housing this conveniently gives me a safe place for the High Voltage connections to the motor and allows me to mount the charger I will be using
I have already milled part of the inside flat to allow good heat transfer from the charger
I then fitted a 6mm spacer plate so that the charger cleared other parts of the casting applied heat sink compound and bolted it in place the charger will be bolted directly to this plate
The reason for all of this is that the housing bolts directly on top of the inverter which is water cooled and I will have the coolant pump running during charging this should provide adequate cooling for the charger (I hope)
