SoCSoHSchätzung
SoCSoHSchätzung, sometimes written as SoC- and SoH-Schätzung, is an integrated approach to estimating both the state of charge (SoC) and the state of health (SoH) of a rechargeable battery. SoC indicates the remaining usable capacity at a given time, expressed as a percentage of the nominal capacity, while SoH characterizes the overall condition of the battery, including capacity fade and increases in internal resistance due to aging. The combined estimation aims to provide accurate real-time information for control, prognostics, and safety.
In practice, SoCSoHSchätzung relies on mathematical models of the battery that relate electrical measurements to the
Sensor data and estimator design must address challenges like nonlinearity, model mismatch, sensor noise, temperature effects,
Applications include electric vehicles, energy storage systems, and portable electronics, where accurate joint estimation improves battery
