Ford Explorer and Capri now support bi-directional charging, allowing users to utilize Ford’s new electric cars with VW’s MEB technology as energy storage for their solar power systems. This innovative solution eliminates the need for a separate battery to store excess solar energy, as the unused power can now be used to charge the electric car’s drive battery. When electricity is needed at home, it can be drawn from the car’s battery, saving money and ensuring energy availability even during power cuts.
The German company E3/DC provides the necessary technology on the house side, including the home power station S10E Compact, a bidirectional DC charging station, and a DC/DC converter. The system allows direct current from the photovoltaic system to flow into the car battery without the need for an inverter, optimizing energy efficiency. An extended-range battery is required on the vehicle side, with a capacity of 77 or 79 kWh to ensure continuous operation of the vehicle.
The system can be combined with flexible electricity tariffs, allowing users to take advantage of cheaper grid electricity prices. The technology enables the stored electricity to be used when grid electricity is expensive, providing additional cost savings. The system also allows users to set lower limits for battery discharge, ensuring that the vehicle remains operational at all times.
Overall, the integration of bi-directional charging technology in Ford’s electric cars offers a convenient and cost-effective solution for utilizing solar power. While the system may be complex and potentially expensive, it provides a sustainable and efficient way to store and utilize renewable energy.
