Cluster Cell Temperature
The following supports Modbus Function Code 03 (Read Holding Registers) only.
Register Address | Data Type | Description | Data Unit | Note |
|---|---|---|---|---|
P+1 | UINT16 | Single Temperature 1 | °C, BMS sends = temperature +40°C | |
P+2 | UINT16 | Single Temperature 2 | °C, BMS sends = temperature +40°C | |
P+3 | UINT16 | Single Temperature 3 | °C, BMS sends = temperature +40°C | |
... | ... | ... | ... | |
P+m | UINT16 | Single Temperature m | °C, BMS sends = temperature +40°C | m ≤ 250 (max number of temps per cluster) |
Additional Info:
Offset formula:
P = 30000 + 500 × nn= cluster index (0 to 31)Addresses
P+1toP+250are used for temperature sensors in each cluster.
