Performance and Safety Evaluation of Lithium-Ion Batteries for Electric Vehicles

Abstract

Performance and safety in battery packs are the major concern in the electrification sector. However, most of the research papers provide information, covering only one or very few parameters to describe the decrement of power and safety in the battery. It leaves aside a holistic and comprehensive study to critically evaluate performance in lithium-ion battery packs. This paper presents ten performance parameters with experiments and theory undertaken to understand the influence in power and safety in lithium-ion battery packs. The influence of performance parameters will provide and integrated approach to clearly identify the problems that induce decrement in performance and compromise safety in the battery. Comprehensive research of performance evaluation in electrification is nascent today, however, when the temperature and vibration parameters are critically reviewed, it has been found that a comprehensive effort is still required to evaluate the impact of vibration and temperature loads in the power performance and safety of lithium-ion battery packs for electric vehicles.
