Accurate SoC estimation is a primary estate in BMS because it depens on non linear elektrochemical reactions, hysteresis, and aging.

State- of- Health Estimation and Remaining Useful Life Prediction
Sohestimation traditionally relies on incremental capacity analysis or impedance spektropy, which require controlled Charging conditions. Deep learning methods can infer SoH directly from regular driving data using techniques such as transfer learning and multitask realning.
