Monitoring Cluster-Level Data
Cluster Statistics Addressing
Per the protocol:
Offset Address P = 1300 + 100 × n
n: Cluster index (0 for Cluster 1, up to 31 for Cluster 32)Each cluster occupies 100
UINT16registers.
Example Mapping
Cluster | Start Address |
|---|---|
1 | 1300 |
2 | 1400 |
3 | 1500 |
... | ... |
32 | 4300 |
Common Metrics per Cluster (relative to P)
Metric | Offset | Notes |
|---|---|---|
Total Cluster Voltage | P+1 | 0.1 V |
Total Cluster Current | P+2 | 0.1 A, offset +3200 |
SOC | P+3 | 0.1 % |
Charge/Discharge Cycles | P+25 | Count |
Cumulative Charge Energy | P+28 | 0.1 kWh, 2 words |
Cumulative Discharge Energy | P+30 | 0.1 kWh, 2 words |
Max Cell Voltage Diff | P+19 | mV |
