Besides the statistics for cycle times, another way to evaluate the battery life loss is the throughput energy method . Based on the LCT–DOD relation curve, the BESS total throughput energy in discharge–charge cycles with different DODs can be derived from product of LCT and DOD in the relation curve .
How do you measure a battery loss?
This method is necessary because there is no practical way to measure losses inside the battery. For the PEU, losses are more directly measured by voltage and current (and thus power) measured on the input and the output sides.
Why is SoC estimation important for EV batteries?
Monitoring and controlling voltage and current are core parameters that require continuous attention and management within a battery system . SOC estimation is a fundamental component in BMS for EVs. It precisely measures the energy stored in the battery, enabling accurate range predictions and efficient energy utilization.
