Good to see lots of people tackling the same problems in different ways. And it's good to see higher power automotive designs where all the nuances are amplified.
The Chinese boards use a piece of copper dipped in solder to create a PCB based bus bar. I tried that approach on my boards but wasn't very happy with it. Looks messy.
I like your stacked busbar design nickskethisniks.
If we design a board for other members to recreate, maybe basing the busbars on easy to get materials could be a focus.
I picked up some bus bars that are commonly available world-wide in the electrical trade.
These copper pre-cut and bent bars are marketed to connect multiples of single DIN rail modules (breakers) together quickly instead of wires.
They are rated at 63A for that purpose.
I'm contemplating a redesign of my power board to use these busbars and maybe others here could consider them to fortify their high current PCB tracks.
