An electric circuit for a high-voltage network of a vehicle. The high-voltage network includes at least two electrical energy stores. The electric circuit includes at least one first switching unit, one second switching unit, and one third switching unit electrically connected to the poles of the electrical energy stores and allowing a parallel and a series connection between the two electrical energy stores. The electric circuit includes at least one fourth switching unit and one fifth switching unit electrically connected to one pole connector each and to one consumer connection. The consumer connection is makes electrical contact with an electrical consumer or a charging unit. The switching units are switchable between an electrically disconnecting and connecting states. The fourth and fifth switching units are galvanically isolating in an electrically disconnecting state. The first switching unit, the second switching unit, and the third switching unit are designed as semiconductor components.
