Abstract:
Electric vehicles are usually thought to be inherently sustainable. However, they are as green as the type of energy source electricity is converted from. So in order to drop dependency on fossil fuels a shift from the actual energy paradigm to one based on renewable sources is needed. Due to the usually intermittent nature of renewable sources, new challenges to overcome have arisen such as the need for systems capable of storing electricity when power production doesn’t match demand. An interesting solution to this is to use electric vehicles batteries in order to store the difference. Through this project, the implementation and control of a bidirectional battery charger up to 3 kW for electrical vehicles is presented. The aim of my collaboration is to modify an already exiting battery charger to allow it working bidirectionally so as to withdraw energy from the battery and inject it back to the grid when the energy demand is greater than the production.
