Thermal Management and Control in Hybrid Electric Vehicle Li – ion Battery

Abstract

This paper presents the thermal management of lithium - ion batteries in electric vehicles that is difficult to achieve better performance and longer battery life. The battery of Li - Ion is the main source of Electric Vehicles and Hybrids Electrical Vehicles. The newly introduced orthosilicate compound Li2MSiO4 is used as a cathode material to improve the thermal behavior of batteries in order to improve thermal efficiency and increase the calendar life of the battery. It is the cheapest material with a high initial load profile and improved ionic conductivity and can withstand better temperatures. The computer fluid flow analysis is carried out using the software ANSYS FLUENT v6.3.2.6 to analyze the battery's thermal system and to investigate the battery's thermal flow during charging and discharge.
