Charging infrastructure - how to contribute to the power grid -

To achieve carbon neutrality, the vehicle mobility is going to be electrified by the 2030's. In the course of mobility electrification, the energy transforming device, charger and power conditioner can help power grid stabilization by smart charging and feeding energy back from the electric vehicle (V2G). This technology can also enable electric vehicles to supply energy to the shelters in the affected areas in the event of a power outage due to natural disasters. We report on the historical achievements, current tasks, and the future direction of V2G from the viewpoint of in-market experience and technical innovation for more than 10 years.
