BATTERY MODULE HAVING BIPOLAR CELL

摘要

A battery module having a bipolar cell includes a plurality of anode plates and cathode plates alternately stacked and connected to each other in series. The anode plates have anode terminals and measuring terminals for measuring a voltage, and the respective cathode plates have cathode terminals and measuring terminals for measuring a voltage, such that steps are formed in the anode terminals, cathode terminals, and measuring terminals. A voltage monitoring terminal part also has steps formed in terminal connecting parts to correspond to the measuring terminals, allowing the measuring terminals to be inserted therein for measuring a voltage of the bipolar cell. The voltage of the bipolar cell is measured in a process to improve defect sorting performance to more easily detect an abnormal cell, thereby making it possible to improve marketability, durability and safety of the battery.

1. A battery module having a bipolar cell, comprising:
a bipolar cell including a plurality of anode plates and cathode plates alternately stacked and connected to each other in series, the respective anode plates having anode terminals formed at ends thereof and having measuring terminals formed at other ends thereof for measuring a voltage and the respective cathode plates having cathode terminals formed at ends thereof and having measuring terminals formed at other ends thereof for measuring a voltage, such that steps are formed in a plurality of anode terminals, cathode terminals, and measuring terminals; and a voltage monitoring terminal part having steps formed in a plurality of terminal connecting parts so as to correspond to the measuring terminals to allow the measuring terminals to be inserted therein, thereby measuring a voltage of the bipolar cell.
