Goals
- Distribute power to all components with maximum efficiency
- Reliable operation
Background and strategic fit
A power distribution board is necessary to supply power to the various subsystems in the vehicle. This board performs distribution, startup, shutdown and emergency shutdown as required in regulations. In addition to supporting powering the boards, it also powers components directly, such as the horn, camera and others.
Assumptions
- Power to the front of the car will be through the main harness
