Review of Battery State-of-Charge Estimation Algorithms

2021
State of charge (SOC) is an important parameter used by a battery management system (BMS). Accurate and robust algorithms ensure the safe and reliable functioning of cells or batteries. Thus far, the algorithms developed depend mainly on the current and voltage data received from individual cells or the entire battery.

EV battery state of charge: neural network based estimation

IEEE International Electric Machines and Drives Conference, 2003. IEMDC'03., 2003
Different electric vehicles (EV) types have been developed with the aim of solving pollution problems caused by the emission of gasoline-powered engines. Environmental considerations promote the adoption of EV for urban transportation. As it is well known one of the weakest points of electric vehicle is the battery system.

Estimating the state of charge of a battery

IEEE Transactions on Control Systems Technology, 2004
This brief considers the state of charge (SOC) estimation problem for electrochemical batteries. Using an electric circuit model of the battery given in the literature, it is shown how the open-circuit voltage (which is directly related to the SOC) can be estimated based on the terminal voltage and current measurements provided there is sufficient ...

Robust optimal estimation over networks: Application to battery state of charge estimation

International Journal of Robust and Nonlinear Control, 2015
SummaryIn this paper, we provide a general framework for robust optimal estimation over a lossy and delayed network. A threshold principle is introduced to integrate network‐induced uncertainties into packet losses, which are modeled with a Bernoulli process.

State of Charge Estimator Design for a Gas Charged Hydraulic Accumulator

Journal of Dynamic Systems, Measurement, and Control, 2015
The gas charged hydraulic accumulators under consideration are used as energy storage devices in automotive hydraulic hybrid systems. The knowledge of the state of charge (SOC) is of utmost importance for an efficient energy management of the hybrid drive-train. Since the direct measurement of the SOC is difficult and costly, an SOC estimator design is
