Fahrzeug mit einer elektrischen Schaltungsanordnung und zwei elektrischen Antriebseinheiten und Verfahren zu dessen Betrieb

The invention relates to a vehicle (1) comprising an electrical circuit arrangement (2), wherein the electrical circuit arrangement (2) has: a traction battery (4); an electrical connection (5) for electrically coupling to a vehicle-external electrical unit (3); a first high-voltage potential (P1); and a second high-voltage potential (P2); wherein the first high-voltage potential (P1) is a positive high-voltage potential and the second high-voltage potential (P2) is a negative high-voltage potential, or vice versa. The circuit arrangement (2) also has two electrical drive units (A1, A2) with a respective inverter (I1, I2) and an electrically coupled electrical three-phase machine (M1, M2) for driving the vehicle (1), and is designed in such a way that the two electrical drive units (A1, A2) can be electrically connected in series between the electrical connection (5) and the traction battery (4) in such a way that the first electrical drive unit (A1) increases the first high-voltage potential (P1) and the second electrical drive unit (A2) increases the second high-voltage potential (P2) from the electrical connection (5) to the traction battery (4). According to the invention, the inverters (I1, I2) each have a capacitor (C1, C2) between a potential line (PL1) of the first high-voltage potential (P1) and a potential line (PL2) of the second high-voltage potential (P2), wherein the circuit arrangement (2) is designed in such a way that the second electrical drive unit (A2) can be electrically connected in series with the capacitor connection of the first electrical drive unit (A1).
