  • E-mobility is a deep confluence between the transport and power sectors, and therefore the integration of electric vehicle (EV) charging infrastructure with distribution grids creates both challenges and opportunities for the EV user as well as the power sector. Transition to electric mobility is expected to have a shift in the refueling mentality for EV users, even more so for residential EV users. It is expected that much of the refueling of the EV, i.e. charging, would be accomplished at the premises of the individual EV owner. EVs which are typically high-power loads, would however significantly add to the power drawn by the household which may result an increase in the sanctioned demand for the household leading to an increase in the electricity bill. Also, distribution grids which are typically designed to cater for the household loads would be significantly stressed with addition of EV charging without any charging management system. Smart charging (V1G), Vehicle-to-Home (V2H), Vehicle-to-Building (V2B), and Vehicle-to-Grid (V2G) in addition to mitigating the negative impacts of EV charging integration can help in providing extra services to the residential EV user, as well the distribution network operator. Using a smart energy controller (SEC), the EV user can potentially optimize their energy consumption profile to lower their annual cost incurred from energy usage. The addition of renewable energy (RE) units can further optimize energy management for the household. The use of such SEC requires a well-defined architecture as well as communication infrastructure between different entities involved. The chapter discusses these energy management architectures and the communication protocols involved. Although these architectures can be used for different applications, the chapter would restrict itself to optimization of household energy consumption.
