Beschreibung
Zusammenfassung:	There is provided a battery system made up by connecting multiple battery units BTU1, BTUn in parallel with each other, the battery units BTU1, BTUn having multiple battery banks V1, Vn, respectively, and multiple switching circuits SW1, SWn connected in series to the battery banks V1, Vn, respectively. A switching circuit SW1, SWn is made up by connecting a first circuit Ca1, Can connected in series to a precharge resistor Zpr1, Zprn having a known resistance value, in parallel with a second circuit Cb1, Cbn having a second switch Sb1, Sbn. Timing for turning the second switch Sb1, Sbn into the on state under an equal-current condition when the connection-target battery unit is connected to the battery system 203A is controlled by a controller CTRA for controlling the respective outputs of the plural battery units BTU1, BTUn.
