Abstract

A battery system (300) having a middle bus line (ML), a positive bus line (PL) and a negative bus line (NL) is provided. The battery system (300) comprises: a battery module (310), a multilevel neutral point clamped inverter (320). One or more direct current to direct current converters (DC/DC) and two or more auxiliary loads (L1, L2, ...) are connected either between the positive and negative bus lines (PL, NL), or between the positive and middle bus lines (PL, ML), or between the negative and middle bus lines (NL, ML). The operation of the DC/DC converters is configurable to balance the loads of the battery module (310) and/or control charging/discharging of the battery module (310). The connections of the two or more auxiliary loads (L1, L2, ...) are configurable to balance the loads of the battery module (310).
