All the electronic components found in the electronics enclosure can be found here.
DC-DC Converter (Power Supply)
The DC-DC converter is what takes power from the high voltage (HV) power from the battery and steps it down to 12V to provide power to the low volage system.
The DC-DC converter is connected to the secondary power board which is connected to the fusebox
Secondary Power Board / Supplemental Power Board
The secondary power board will either be powered by the DC-DC converter or 2 supplementary batteries.
During startup, the board will be powered by the supplemental battery, but once the ignition sequence is done and BPS has declared it safe for the car’s system to be powered by our battery pack, the secondary power board will switch what’s powering the fusebox to the DC-DC converter
Fuse Boxes
There will be two fuse boxes inside the EE
...
These fuse boxes will be powered by the secondary power board and will supply power to all low-voltage components on the car.
MPPT Board (x3)
The MPPT board is what measures the current of each subarray
...
The MPPT boards talks to each other and the other boards in the car through Controller Area Network (CAN)
Blackbody A (RTD Board)
The RTD detects the temperate sensors within the array
As of 2023, these sensors have not been implemented, but we left a spot for them within the EE
Horn Board (1-Channel Relay)
The horn board turns the horn on and off based on driver input. It is simply a 1-Channel Relay to toggle the state of the horn.
Raspberry Pi (Data Aq/Telemetry)
The Telemetry board is Data Acquisition's primary board, and it is used to communicate the status of the car to people outside.
...
The ethernet cable should have its own hole on the top of the electronics enclosure
Contactor Driver Board (x2)
There are two contactor drivers located inside the EE.
...
These boards control the HV Contactors and are part of the ignition sequence.
Kilowav Contactors (x2)
