This is necessary because power generation from renewable energies depends on availability of sun and wind and can therefore only be controlled to a limited extent. For this reason, network operators utilize so-called electricity balancing to ensure that the power grid remains stable, despite increasing integration of renewable energies.

If the driver wants to retain a certain amount of electric range or to drive certain route segments on electric power, he or she can use the Hold or Charge function to precisely adjust the charge of the battery even without charging from the power grid. The dynamic steering varies its ratio as a function of driving speed.
