Understanding the Challenges of Measuring Battery Cell Voltage (Download)
Knowing the voltage of a battery cell is essential for ensuring the cell’s health, state of charge (SOC), safety, and performance. Monitoring cell voltage while the cell is in use can help identify problems such as wear-out, improper charging/discharging, or internal faults.
During testing, accurate cell voltage measurements are critical for evaluating how the cell responds under load, during charging and discharging cycles, and across various environmental conditions. This data helps identify issues such as capacity loss, cell imbalance, or potential safety risks like thermal runaway.
