Industrial EV Battery Performance Evaluation: A Review From the Instrumentation Perspective

The increase in interest in lithium-ion battery cell performance indicators has been propelled by automotive manufacturers’ paradigm shift from internal combustion engine (ICE) vehicles toward electric vehicles (EVs). Accordingly, recent literature has seen a surge in the number of reviews related to nondestructive evaluation for lithium-ion batteries in EVs. Quantifying the battery cell performance is a key to successfully enabling the transition from ICE to EVs. This review seeks to provide an instrumentation and measurement perspective on the state of the art for battery cell performance indicators, including a deeper dive into their limitations and capabilities. This article will cover the most commonly employed measurement techniques, including electrical techniques, mechanical methods, and thermal analysis techniques. This article is organized by measurement technique, where each section will include an introduction to the technique, how it applies to batteries in the EV space, and will conclude with recommendations for extending the state of the art.
