Battery pack remanufacturing process up to cell level with sorting and repurposing of battery cells

Behavior data of battery and battery pack SOC estimation under different working conditions

This article provides the dataset of operating conditions of battery behavior. The constant current condition and the dynamic stress test (DST) condition were carried out to analyze the battery discharging and charging features. The datasets were achieved at room temperature, in April, 2016. The shared data contributes to clarify the battery pack state-of-charge (SOC) and the battery inconsiste...

A Cell Level Model for Battery Simulation

An equivalent circuit model is the most common and straight-forward way of representing the dynamic behaviour of a lithium-ion battery. In literature, many examples of circuits are proposed and various techniques are also discussed for parameterisation of the models. In this paper a second order equivalent circuit is proposed and the parameters identification method by Hybrid Power Pulse Charac...

An Acausal Li-Ion Battery Pack Model for Automotive Applications

In this work, a novel acausal and reconfigurable battery pack model is presented. The model structure adopted for the battery cell is based on an equivalent circuit representation. The circuit elements are modified to take account of both hysteresis and diffusion limitation. The latter is known to be a nonlinear function of large operating currents or long operating times. It is shown that the ...
