Elements

Not a huge amount of progress since the last post due to some long days at the office, but I did pick up the needed sheet metal. My old favourite metal supplier in Perth (Peddie's) having closed down I had to go to Dundee instead. 

However the weather has also been pretty grim so today was spent hibernating inside with the wood stove on, building the battery management system PCBs which will look after the expensive lithium cells. 

This is a pretty simple system of my own design which has evolved slightly from the last car it was used in.  Each board has 12 channels and can be grouped together or spread out over the pack with a communication bus linking them together and to the vehicle's charge and drive systems.
