A Virtual Sensor for Electric Vehicles’ State of Charge Estimation [PDF]

Electronics, 2020
The estimation of the state of charge is a critical function in the operation of electric vehicles. The battery management system must provide accurate information about the battery state, even in the presence of failures in the vehicle sensors. This article presents a new methodology for the state of charge estimation (SOC) in electric vehicles ...

State-of-charge estimation for batteries: A multi-model approach [PDF]

2014 American Control Conference, 2014
Monitoring the state-of-charge (SoC) for batteries is challenging, especially when a battery has time-varying parameters. We propose to improve SoC estimation using an adaptive strategy and multiple models in this study, developing a unique algorithm called MM-AdaSoC.

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.
