A method for operating a switching device, in particular a method for operating a switching device of an energy storage system comprising a common traction voltage bus and a plurality of battery packs arranged in parallel connectable to the common traction voltage bus. The switching device includes an associated contactor for each battery pack configured to connect and disconnect the battery pack to and from the common traction voltage bus by closing and opening. The method includes: identifying an unconnected battery pack to be connected to a common traction voltage bus; determining a voltage difference between the common traction voltage bus and the identified battery pack; adjusting a current of the common traction voltage bus to reduce a voltage difference between the common traction voltage bus and the identified battery pack; a contactor associated with the identified battery pack is closed to connect the identified battery pack to the common traction voltage bus.

    用于操作开关装置的方法,尤其是一种用于操作能量存储系统的开关装置的方法,所述能量存储系统包括公共牵引电压总线和可连接到公共牵引电压总线的多个并联布置的电池包。开关装置包括用于每个电池包的相关联的接触器,所述接触器被配置为通过闭合和断开将电池包连接到公共牵引电压总线以及从公共牵引电压总线断开。所述方法包括:识别要连接到公共牵引电压总线的未连接的电池包;确定公共牵引电压总线与所识别的电池包之间的电压差;调整公共牵引电压总线的电流以减小公共牵引电压总线与所识别的电池包之间的电压差;闭合与所识别的电池包相关联的接触器以将所识别的电池包连接到公共牵引电压总线。
