The climate change crisis which has been caused by global warming has seen the rise of the need for cleaner energy which is less harmful to the environment. Since modern day mode of transportation is amongst the major contributions to global warming, greener vehicles as electric vehicles have slowly started replacing fossil fueled vehicles. Electric vehicles are very desirable as they are clean and have no emissions, meaning they do not produce greenhouse gases. Despite the advantages of using electric vehicles, they have problems which diminish their popularity in usage and the major issue is the range of driving. Electric vehicles can travel a limited distance before needing to recharge the battery, which takes longer than refueling a fossil fueled vehicle. Extending the range for driving of EVs is hinged upon the functionality of the EV battery and power electronic converters. The main issue currently is to find the best technology and methods to incorporate so that the efficiency of electric vehicles is maximized. An important way of maximizing efficiency is through ripple current management of the battery and power electronic converters where power losses are very prominent. The research will be focusing on how to improve the battery and power electronic converters lifespan through analysis of ripple current in electric vehicles. Management of ripple current will reduce power losses which increases the travel range of electric vehicles and make them more efficient. The relationship between power loss and temperature in batteries and power electronic converters is also important in assessing the reliability of electric vehicles since these parameters affect the lifespan of the components.
