Audi Bidirectional Charging
17Increasing network stability, lowering electricity costs, and contributing to climate protection – that is the vision that Audi and the Hager Group are pursuing. The incorporation of the electric car into the domestic grid is at the core of an innovative research project on bidirectional charging. This offers major advantages in combination with a photovoltaic system in particular. Excess PV electricity can be stored temporarily and output as needed.
Audi has committed to the objectives of the Paris Climate Agreement and is working on making its vehicle fleet CO2-neutral by 2050. In order to achieve this aim, the brand with the four rings is pursuing a broad electric offensive that involves launching around 20 fully electric models by 2025. And not only that: The electric car is to evolve into part of an increasingly broad mobility offer and become an element of the sustainable energy transition.
In the first half of 2020, renewable energies contributed more than 50 percent to the German electricity mix for the first time. However, the increasing percentage is also accompanied by a basic dilemma of wind and solar power: The generation of electricity is not always constant. On sunny days and phases with strong winds, there is often a lack of capacity to store the generated energy that the grid cannot use.
