Why Coulomb Counters Drift

Current integration is valuable for estimating state of charge, but small measurement errors accumulate over time.

Why it matters

Periodic synchronization at a known full condition and accurate current calibration help keep the displayed percentage aligned with the battery's actual operating window.

What to check

• Verify the configured battery capacity
• Check zero-current calibration when the system is idle
• Review the monitor's full-charge synchronization conditions

Read the trend, not one sample

Battery and gateway measurements change with load, charging stage, temperature, and timing. Compare repeated conditions and preserve a known-good baseline before drawing conclusions from a single reading.

The JKBMSR safety boundary

JKBMSR provides remote visibility, history, and alerts. It does not replace the BMS, fuses, contactors, charger controls, or the equipment manufacturer's safety instructions. Any sign of swelling, smoke, unusual odor, rapid heating, damaged wiring, or unstable voltage calls for immediate safe shutdown and qualified inspection.

Practical takeaway

Use the dashboard to turn this topic into a repeatable observation: record the conditions, compare the same measurements over time, and act on persistent changes rather than guesswork.
