| 13 | The accumulator motherboard serves the purpose of connecting the IMD, BMS master, TSAL green, AIR-relays, DCDC and the car together. In addition it host AMS and IMD error signal latch, powerstages for the SDC switching of AMS and IMD signals, powerstages for AIR and precharge relays. The motherboard has a power supply for itself, the BMS, IMD and TSAL green boards and lowpass filters and voltage deviders for all the signals going to BMS and TSAL green boards. | ||

| 17 | The motivation for using a motherboard in the accumulator is to eliminate as many wires as possible in the accumulator. | ||
| 18 | |||
| 19 | The entire form factor of the board is made to fit the IMD using nylon standoffs and bolts, the IMD is connected to the motherboard using Würth connectors and hook up wire. The TSAL green and BMS boards are connected to the motherboard using board to board connectors and the same standoffs that the IMD is connected with. This is intended to ensure the entire assembly is sufficiently stiff. | ||
