Battery monitoring refers to the continuous measurement, recording, and analysis of key parameters of a battery system to ensure safe, efficient, and reliable operation. It is a critical function in applications ranging from electric vehicles (EVs) and energy storage systems (ESS) to uninterruptible power supplies (UPS) and telecommunications infrastructure.
Key Parameters Monitored:
Voltage (cell, module, and pack level)
Current (charging and discharging rates)
Temperature (critical for thermal safety and performance)
State of Charge (SOC) – estimated available capacity
State of Health (SOH) – overall condition relative to new
Impedance / Resistance – indicates degradation or failure risks
