Bidirectional charging optimizes the use of renewable energy, driving the energy transition forward at an even greater pace.

Electric cars are capable of much more than “simply” being quiet and emissions-free. Equipped with bidirectional charging technology, they can store electricity and feed it back into the grid later.

Cars with solar roofs already exist. Now, the Fraunhofer Institute for Solar Energy Systems (ISE) is attaching a solar-active surface to a car hood. Now the researchers hope it will be ready for mass production.
