Data logging

Definition

Data logging is the process of collecting and storing data over time, often using sensors and monitoring systems to capture information related to performance and operational metrics. This technique is essential for monitoring battery systems, allowing for real-time assessment of performance, temperature, voltage, and other critical parameters. By maintaining a record of these data points, data logging enables better analysis, diagnostics, and management of battery systems.
