Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
This paper presents a reference model estimator for the state of charge of a battery based on a Thevenin equivalent electrical circuit model. State-of-charge estimation is essential in battery management systems across devices to plan operating times, charge profiles, and supply profile from battery to the load. The presented estimator is intended for an online application and uses the current and voltage at the battery terminals to perform the estimation. The battery is connected to a step-down converter of an extended conversion ratio that operates in closed loop with the objective of maintaining a DC constant voltage across a load. A control consisting of a current control loop and a voltage control loop is used to regulate the output voltage of the converter. The controller guarantees closed-loop stability and provides damped behavior and zero steady-state error for constant output voltage references. Numerical results are presented to evaluate the estimator based on the reference model.
