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

2014 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.

Adaptive estimation of state of charge for lithium-ion batteries [PDF]

2013 American Control Conference, 2013
State of charge (SoC) estimation is a fundamental challenge in designing battery management systems. An adaptive SoC estimator, named as the AdaptSoC, is developed in this paper. It is able to estimate the SoC when the model parameters are unknown, through joint SoC and parameter estimation.
