Abstract

The use of electric vehicles (EV) has received much attention at the present time due to the readiness of technology, besides becoming a potential solution towards environmental pollution. The mechanics of EV is to function by the use of high energy density, with lithium-ion batteries being one of the popular choices. The challenges, however, lie in the thermal management of lithium-ion batteries due to poor heat resistance of the lithium-ion. Efforts have been put in assessing the performance of the lithium-ion batteries, but little attention has been given to the use of probabilistic approaches. Herein, this paper provides basic probabilistic assessment framework of failures in electric vehicle^s lithium-ion battery. The approach describes a simple example on how the internal battery faults and their causes can be translated into solutions in determining the probability of failure of the incident. Although limitations in providing detailed solutions using the actual design and operational data, the proposed framework is able to provide a more accurate estimate in the performance of the lithium-ion batteries.
