E vehicle conversion and Charging infrastructure

Abstract

EV charging system is a system in which single or certain number of vehicles can be charged at a time under a single roof. EV runs on battery i.e., on D.C. power source therefore a convertor is required to convert available A.C. power into D.C. power to charge electric vehicle battery. D.C. fast charging stations are becoming more popular nowadays because they have capability to charge EV at a much faster rate than normal A.C. charging. Tesla motors in 2012 made first 480 volt D.C. charging system, which has a supply power range to approximately 250kW. Battery technology which is available now, has a capability to get charged less than an hour safely. Li-ion battery technology is breakthrough technology in EV industries. Due to high charge discharge cycle they are becoming more reliable and adaptive. High voltage charging is more preferred over low voltage charging because in high voltage system charging could be done at a much faster rate as energy transfer rate increases. A special switch system could be made so that same number of batteries can be charged at a much faster rate. Fast charging will lead to increased load on the grid hence special transmission system and equipments are required to handle such vast load. Solar charging infrastructure is a good option here as it provides large amount of power to be served at a source.
