The purpose of this legislation, known as the Bidirectional Electric Vehicle Charging Act of 2025, is to promote the development and use of bidirectional charging technology for electric vehicles. Bidirectional charging allows electric vehicles to not only draw power from the grid but also send power back to it or to other devices. This can enhance energy efficiency, support renewable energy integration, and improve grid reliability. The key provisions of the Act require the Secretary of Energy to create a National Electric Vehicle Bidirectional Charging Roadmap.
