Sensing pcb structure of battery unit

A sensing PCB of a battery unit, the sensing PCB being coupled to the battery unit in which a plurality of cylindrical battery cells, each of which has an upper surface provided with a positive electrode and an negative electrode, are mounted, and being configured to be electrically connected to an electrode network configured to connect the plurality of battery cells in series and parallel and provided in the form of a plurality of separated busbars, and the sensing PCB comprising:

• a substrate part provided in a “C” shape and fixedly coupled to the battery unit by a coupling means in a direction of the electrode network of the battery unit;
• a plurality of electrode parts provided as a plurality of conductors arranged on a lower surface of the substrate part facing the direction of the electrode network, and configured to make contact with respective ends of the electrode network when the substrate part is fixedly coupled to the battery unit;
• a pattern part formed on the substrate part and provided in the form of a printed pattern selectively connected to the plurality of electrode parts;
• and
• an output part located on an upper surface of the substrate part, configured to be electrically connected to the pattern part, having a connection terminal to which an input terminal of a measuring device for measuring an electrical signal is connected, and configured to output an electric signal for each connection section of the electrode network to which the plurality of battery cells are connected through the pattern part.
