Abstract:
Various modern applications in the transportation industry necessitate high performance power sources with excellent energy densities. A characteristic example of this need would be tractor-trailer trucks, as they are required to carry heavy loads as far as possible before refueling. Another, less commercial, example is the family car. Being a common method of everyday transportation, a car is also required to travel long distances before needing to refuel. This paper examined the properties and performance of the lithium-ion battery against those of established technologies, such as lead-acid batteries and gasoline. Additionally, the tools used in modern finite element analysis are examined. The knowledge of the lithium-ion batteries and finite element methods were used to revise the design of an existing lithium-ion battery pack for reduced manufacturing time, and to compare the revised design’s predicted thermal characteristics with those of the original design.
