AI Customer ServiceConclusions State estimation is one of the most basic functions of BMS. Accurate state estimation can prolong the battery life and improve battery safety. This paper comprehensively reviews the research status, technical challenges, and development direction of typical battery state estimation (SOC, SOH, SOE, and SOP).
As the monitor of the power system, state estimation is one of the core key functions of a BMS. Commonly estimated battery states include the state-of-charge (SOC) , state-of-health (SOH) [14, 15], state-of-power (SOP) , state-of-energy (SOE) , and state-of-safety (SOS) [18, 19].
Battery state estimation approaches were introduced from the perspectives of remaining capacity and energy estimation, power capability prediction, lifespan and health prognoses and other important indicators relating to battery equalization and thermal management.
With the development of big data, intelligent algorithms, and cloud platforms, a trend of smart and networked BMS is becoming increasingly obvious, which will effectively improve the battery state estimation accuracy and thus improve the life and safety of batteries.
