8.2. CAN Bus Protocol Support

Nuvation Energy BMS uses a flexible CAN reporting implementation which maps BMS software
registers to CAN message identifiers. It is based on the CAN 2.0 standard, with the exception that
Remote Transmission Requests (RTR) are not supported.
The parameters for the CAN interface are:
▪
Baud: 500 kbit/s
▪
CAN ID: 11-bit Identifier (Base frame format)
▪
CAN payload length: variable from 1 byte to 8 bytes based on register size

8.2.1. CAN Reporting and Commands

The CAN interface provides the following capabilities through configuration:
▪
Reporting of up to 64 individual registers within the battery management system.
▪
Bulk-reporting of registers that represent sets of measurements (e.g. cell voltages and
temperatures)
▪
Creation of customizable commands to the battery management system to implement actions
such as:
