Bipolar storage battery system

A bipolar storage battery system (10) comprising a first storage battery unit (12) and a second storage battery unit (14), each including at least one storage battery module (16),

• wherein each storage battery unit (12, 14) comprises a positive pole and a negative pole and corresponding contacts (12-1, 12-2;
• 14-1, 14-2),
• wherein the two storage battery units (12, 14) are connected in series by means of the corresponding contacts (12-2, 14-1), and a center tap (18) results from the connection,
• characterized by
• a shared control unit (20) for the two storage battery units (12, 14) comprised by the bipolar storage battery system (10) and intended to ensure electrical and/or functional safety of the bipolar storage battery system (10),
• wherein the contacts (12-1, 14-2) remaining after the connection of the two storage battery units (12, 14) to form the center tap (18), as a positive and a negative pole of the storage battery system (10), are routed across the control unit (20) to the outside for an external tap as a positive and a negative external terminal (22, 24), and
• wherein the center tap (18), as a neutral pole of the storage battery system (10), is routed across the control unit (20) to the outside for an external tap as a neutral external terminal (26).
