Abstract

The following descriptions relate to a system for controlling an electrical storage unit (12) in a vehicle, comprising: an electrical storage unit (12), wherein the storage unit has at least two storage banks (14, 16); a first contactor (18) arranged between a first storage bank (14) and a second storage bank (16), wherein the first and second storage banks (14, 16) can be electrically coupled to each other via the first contactor (18); a first DC-DC converter (20); an intermediate circuit (22) connected to the storage banks (14, 16) and the first DC-DC converter (20), with an intermediate circuit capacitor (24); a second contactor (26) arranged between the first storage bank (14) and the intermediate circuit capacitor (24) on the intermediate circuit (22); a third contactor (28) which is arranged between the second storage bank (16) and the intermediate circuit capacitor (24) on the intermediate circuit (22);wherein the intermediate circuit capacitor (24) is arranged between the second contactor (26) and the third contactor (28) in the intermediate circuit (22); wherein the first DC-DC converter (20) is configured to supply a first low-voltage electrical system with a low voltage and to precharge the intermediate circuit capacitor (24).
