Abstract
This paper examines the specifications of lithium battery cells, which are considered one of the most vital sources for electrical energy storage units. The specifications have been covered to associate battery performance with its usage for electrically powered motor vehicles. With the motivation of rapid deployment of electric vehicles (EVs) around the world, the key contribution of this study is to provide a comparative investigation of well-known commercially available Li-ion battery cells used as a pack for electric race car. Five lithium cells from different manufacturers were analyzed for start voltage, end voltage, current, and the use of active cooling under different test conditions. Thermal imaging was used to provide more comprehensive analysis of tested battery packs. The outcomes of this experimental investigation are described in the sections below in the order in which the analyses were conducted. The key findings of this study are presented in the conclusion section.
Highlights
In principle, electric vehicles (EVs) use an electric motor for traction and such things as chemical batteries, fuel cells, ultracapacitors, and flywheels for energy sources
A comparative analysis of lithium battery cells used as a pack for an electric race car was performed for different brands from different manufacturers
The key contribution of this research is to provide an experimental comparative thermal analysis for of lithium ion (Li-ion) battery cells used as a pack for electric race car
Summary
Electric vehicles (EVs) use an electric motor for traction and such things as chemical batteries, fuel cells, ultracapacitors, and flywheels for energy sources. A comparative analysis of lithium battery cells used as a pack for an electric race car was performed for different brands from different manufacturers. The key contribution of this research is to provide an experimental comparative thermal analysis for of Li-ion battery cells used as a pack for electric race car. It investigates five lithium cells from different manufacturers for start voltage, end voltage, current, and the use of active air cooling under different test conditions. A group of modules is connected electrically to form a battery pack that contains a long charge/discharge time and low- and high-power energy density [11,13].
