State-of-Charge estimation algorithms and their implications on cells in parallel [PDF]

open access: yes2014 IEEE International Electric Vehicle Conference (IEVC), 2014
State-of-Charge (SOC) of a battery is one of the most important parameters used by a Battery Management System (BMS). It is subsequently very important for the efficient functioning of an electric/hybrid vehicle. Since, the SOC is a derived quantity, it is important that the algorithm, on which the estimator is based, is robust and accurate.
