1.Brief Introduction


Three-phase Net Meter for V2G enabled charging stations of electric vehicles, Vehicle-to-Grid (V2G) technology has emerged as an effective solution to support the grid that operates EV in charging and discharging mode. V2G establishment involves three elements amongst the bidirectional metering plays a significant role. This paper aims to design and develop a cost-effective three-phase Net Meter. It allows the bi-directional flow of current and generate bills at an associated subsidize rates.
