Bi-directional DC-coupled EV charger

SolarEdge Technologies’ new Bi-Directional DC EV Charger enables solar-powered Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) functionalities. The charger allows charging the EV directly from PV with no AC-to-DC power conversions, fast charging of up to 24kW by simultaneously drawing electricity from the PV array, the home battery, and the grid, bypassing the home’s AC infrastructure and the limitations of the car’s onboard EV charger, and charging the EV with excess PV, leveraging the SolarEdge inverters DC to AC oversizing (up to 200%). In addition, SolarEdge’s ONE energy optimization system offers enhanced savings by applying smart algorithms to calculate dynamic utility prices and autonomously charge and discharge the EV battery. This will enable homeowners to receive payments from their electricity supplier during demand response events, by discharging their stored EV battery power back to the grid (V2G). In addition, the EV battery can function as a large home battery storage solution of up to 50kWh, both on and off grid, enabling homeowners to use their EV to back up their homes for extended periods during an outage (V2H). The Charger is compatible with both 400V and 800V EV powertrains via a standard CSS connector.
