Predicting remaining discharge time of a Lithium-ion battery by using residual capacity and workload

Abstract

This paper presents a simple, yet effective model for predicting the remaining discharge time of a Lithium-ion battery. It uses workload and residual capacity to be discharged as parameters to estimate the remaining discharge time. After comparing batteries from two manufacturers of five different types, the differences between observations of the remaining discharge time and that of our model are all within 1%. This model works for varying workload estimation as well.
