Life Cycle Analysis of Lead Acid Battery used in Electric Vehicles (3 Wheeler) in Bangladesh

Lead acid batteries have been rapidly used in electric vehicles (3 wheeler) in Bangladesh with typical environmental problems such as consumption of resources and heavy metal pollution. Thus to conduct a comprehensive analysis of the environmental impact of the battery to reduce environmental pollution is urgent. In this paper a life cycle analysis conducted by SimaPro software is applied to analyze and compare the environmental impact of lead acid battery (LAB) within the system boundary of "cradle-to gate". The results showed that the overall impact of LAB production on environment is the smallest. The key substances that causes the environmental impact of LAB is production stage (12.56 %) & use stage of (85.56 %) the batteries. This research work will provide a quantitative assessments of the environmental impact of battery which will be very important to take necessary prevention measures during disposals. This can obviously create scopes of further research in this area.
