the energy storage switch has stored energy and cannot be closed
Energy Storage and Transport: What''s the Connection?
In these situations, energy storage systems connected to e.g. the charging points, will discharge the energy previously stored, such as when there is an excess of sun or wind power. But there are also other ways to reduce costs and stress on the energy system, e.g. vehicle-to-grid integration.
