Beschreibung
Zusammenfassung:	The invention relates to a circuit for an electrical energy storage system (100) with two energy storage units (R1, R2) respectively comprising a first and a second pole connection (P1, P4, P3, P2), said circuit comprising: at least one first and one second input (E1, E2), at least one first and one second output (A1, A2), a first switching element (S1) between the first pole connection (P1) of the first energy storage unit (R1) and the first output (A1), and a second switching element (S2) between the second pole connection (P2) of the second energy storage unit (R2) and the second output (A2), a third switching element (S3) being arranged between the second pole connection (P3) of the first energy storage unit (R1) and the first pole connection (P4) of the second energy storage unit (R2), a fourth switching element (S4) being arranged between the second pole connection (P3) of the first energy storage unit (R1) and the second pole connection (P2) of the second energy storage unit (R2), and a fifth switching element (S5) being arranged between the first pole connection (P1) of the first energy storage unit (R1) and the first pole connection (P4) of the second energy storage unit (R2), the energy storage units (R1, R2) being connected in parallel or in series according to the switch position of the third, fourth and fifth switching elements (S3, S4, S5).
