Data for Modelling and experimental evaluation of parallel connected lithium ion cells for an electric vehicle battery system

Listed in figshare and Loughborough Research Repository — shown once because both records carry DOI 10.82444/warw.33973837.v1

Variations in cell properties are unavoidable and can be caused by manufacturing tolerances and usage conditions.

Description

As a result of this, cells connected in series may have different voltages and states of charge that limit the energy and power capability of the complete battery pack. Methods of removing this energy imbalance have been extensively reported within literature.

However, there has been little discussion around the effect that such variation has when cells are connected electrically in parallel. This work aims to explore the impact of connecting cells, with varied properties, in parallel and the issues regarding energy imbalance and battery management that may arise. This has been achieved through analysing experimental data and a validated model.

The main results from this study highlight that significant differences in current flow can occur between cells within a parallel stack that will affect how the cells age and the temperature distribution within the battery assembly.<br><br>Characterisation_Cell_1_Aged Characterisation_Cell_1_New Characterisation_Cell_2_Aged Characterisation_Cell_2_New Characterisation_Cell_3_Aged Characterisation_Cell_3_New Characterisation_Cell_4_Aged Characterisation_Cell_4_New Characterisation_Parallel_Aged Characterisation_Parallel_New Cycle_Ageing_0-50_Cell_2 Cycle_Ageing_0-50_Cell_3 Cycle_Ageing_0-50_Cell_4 Cycle_Ageing_100-150_Cell_4 Cycle_Ageing_50-100_Cell_3 Cycle_Ageing_50-100_Cell_4 Parallel_Pulse_Test_Low_SOC Parallel_Pulse_Test_Mid_SOC Validation_Profile_Cell_1 Validation_Profile_Cell_2 Validation_Profile_Cell_3 Validation_Profile_Cell_4 Validation_Profile_Parallel
