Units - Nuvation Energy NUV300-BC-12 Product Manual

used for register addresses. For example:
@component_name[index].register_name
expands to the address of component_name.register_name at index in the system.

7.1.2. Units

A standard set of types/units has been adopted for use within Nuvation Energy BMS for the
measurements and configuration settings. Unless otherwise noted, the units used within the firmware
should be assumed as defined below.
Type Units
Address none
Boolean false=0, true=1
Charge mAh
Count number
Crc16 none
Current mA
Energy Wh
Int64 value
ImpedanceMili mΩ
IpAddress IP
LogLevel none
MicroOhms μΩ
Microseconds μs
Percentage %
PowerW W
SoftwareId enum
Temperature °C
String none
UInt16 value
UInt64 value
Voltage mV
Every register within the firmware has an associated type that defines the expected units for that
register.
