For Electrical Integration and firmware testing of MSXVI, our plan is to create an electrical mock-up of the car so that we can test all electrical functions without being connected to the car. This will also help with validating any new boards, as we would be able to plug it in and make sure that it works.
This electrical mock-up will be built on a wooden board with mounts for all the boards on the car. All the car's wiring will be able to be routed around this board to connect everything together.
We also have a mock battery (36S 1P) so that we can test the functions of the BMS. This section of the mock-up will be removable so that we can test AFEs independently.
The electrical mock-up will follow the MSXIV block diagram, found in the MSXIV Electrical VDR:
Plan for creation of mock-up:
- Print out 1:1 scale models of all boards
- Label the connectors, types (MX150L, Duraclik, Ultrafit, etc.) and pinouts
- Layout all board print outs on a piece of wood base board in a roughly similar manner to where they will be in the car
- Figure out all of the cables that we need to connect, what pinouts, wire gauges, colors, etc.
- 3D Print mounts for all the boards that will go in to the car (3D prints and M2.5 heat set inserts)
- Use VHB or hot glue to attach the mount to the wood base board
- Define lengths for all cables
- Get help from first years to build all the cables
- We may need to order more wire in order to complete this.
