1. An electric circuit (3) for a high-voltage network (2) of a vehicle (1), wherein the high-voltage network (2) includes at least two electrical energy stores (17, 18), the electric circuit (3) comprising:
at least a first connection point (4) and a second connection point (5) configured for electrical connection to a consumer (19) and/or a charger (21),
at least a first switching unit (6) arranged between a first pole connector (13) configured to make electrical contact with a first pole (17 a) of a first electrical energy store (17), and the first connection point (4),
at least a second switching unit (7) arranged between a second pole connector (15) configured to make electrical contact with a second pole (18 b) of a second electrical energy store (18), and the second connection point (5),
at least a third switching unit (8) arranged between the first connection point (4) and a third pole connector (14) configured to make electrical contact with a first pole (18 a) of the second electrical energy store (18), wherein the first connection point (4) is arranged between the first switching unit (6) and the third switching unit (8), and
at least a fourth switching unit (9) arranged between the second connection point (5) and a fourth pole connector (16) configured to make electrical contact with a second pole (17 b) of the first electrical energy store (17),
wherein the switching units (8, 9) are switchable between an electrically connecting state and an electrically disconnecting state,
wherein the first switching unit (6) and/or the second switching unit (7) are designed to be galvanically isolating in the electrically disconnecting state, and
wherein the third switching unit (8) and/or the fourth switching unit (9) include semiconductor components.
