Summary:

This log will contain the basic communication data format for the EV box system. It will be updated as needed.

TODO: Make this a page on github as well to track changes as they will affect code revisions
TODO: Create message ID groups to standardize priority
TODO: Decide and list the default baud rate (bandwidth calculations needed)

CAN BUS

Data Field Standard

CAN bus data field format. All units are in SI-base and SI-derived format with conversions done at the display level.

Rules:

• Fit monitoring data in a single 8-byte frame
• Include unit name with unit
• All data in ASCII for human readability
• Decimal place always included but not necessarily in a fixed position. Chart lists defaults. (Exception: RPM)
• Decimal at the end of the number indicates a whole number (example: 1300.KWH decimal always included)

Monitoring Data

This data is sent from nodes and includes voltage, amperage, speed, and temperature information.

Control Data

Message ID

Lowest numbered ID gets the highest priority message

Rules:

• 11-Bit identifier
