he hybrid-electric and electric vehicle (HEV/EV) market has been growing rapidly in India. Electric vehicles are viewed not only as transportation with clean energy, but also as a mobile energy storage device. As the number of electric vehicles increase on the road, they will no doubt need to connect with the surrounding energy infrastructure to manage the load demand. In this paper we are going to talk about Vehicle-to-Grid, which is also called as V2G Technology and test requirements. Currently power electronics, automotive testing and grid compliance tests are seen in isolation. But as new technologies like Vehicle-to-Grid evolves, the entire energy
eco-system is going to converge. The test solutions also need to converge to meet interoperability between automotive EV, grid system and infrastructure.
Electric Vehicle role in Energy Eco-system: Electrical vehicles are going to play very important role in the energy eco-system. The growth of electric vehicles and the smart grid has led to the creation of vehicleto-grid (V2G) technology. Imagine using your electric vehicle to power your home during a power outage, or transferring the energy from your car to a grid. This enables electric vehicles to serve as mobile energy storage devices. This would elevate the

energy economy as it looks to meet the peak load power requirements. Vehicle-to-Grid Technology: Vehicle-to-grid technology involves drawing unused power from the car into the smart grid. V2G, which is also known as vehicle-grid integration (VGI), can help the energy grid supply electricity during peak hours. It can also create an extra power source when weather-dependent renewable energy sources are not available. For example, a home that uses solar power cannot generate electricity at night, but an electric vehicle could provide a secondary source of power if needed. Electric vehicles will be used as mobile
