This has been an interesting exercise, found a couple of issues in the circuit, and made some changes to the keypad connection. Otherwise no errors that I can find. I will have to modify the mosfet synchronous driver card as the driver chip "Drain" voltage sense has a 200v max, so will add a resistive divider.

Here is the bulk of the schematic which I drew up to check the pcb layout, not shown are the actual CPU card details or the 2 charge state output relays, reason I have for using the plugin CPU card is to make it an easy exercise to replace the CPU with another, like one of the "Mite family"
