May 27, 2020—Tesla has made its Model 3 and possibly its Model Y ready for bidirectional charging, reported Electrek.

Vehicle-to-grid technology enables a car to send power back into the grid with a bidirectional charger.The function could power a Tesla owner's home or contribute to renewable energy by sending power back. 

 With this technology, electric car fleets could save billions of dollars but it does present some challenges. Bidirectional charging could accelerate battery degradation.
