- a predetermined edge region including a hole formed in the center of the PCB 500 is not formed of a circuit, and is formed of a conductive material to enable electrical connection.
- connection member 300 may form a gas discharge hole 311 formed from the center to the outer surface on the upper side that abuts in the longitudinal direction of the electrode.
- the gas discharge hole 311 serves to discharge the gas generated during the charging and discharging of the ultracapacitor to the outside.
- the reason why the gas discharge hole 311 is formed to be formed from the center to the outer surface on the upper side that is in contact with the electrode in the longitudinal direction is that the gas generated during charging and discharging of the ultracapacitor is ejected through the hole formed in the center of the electrode Because it becomes.
- the gas discharge hole 311 is not limited thereto, and may be configured in various shapes as illustrated in FIGS. 9A and 9B. That is, the gas discharge hole 311 may be a form that can discharge the gas generated during the charging and discharging of the electrode to the outside of the connection member 300.
- connection member 300 forms a hole through which an electrode terminal is inserted and passed through, ie, a hollow, so that the electrode is charged or discharged without forming a separate gas discharge hole.
- the gas generated at the time can be discharged to the outside.
- FIG. 10 is a diagram illustrating an ultracapacitor module according to another embodiment of the present invention.
- the bus bar 1010 may be formed by vertically bending a central hole portion of the bus bar 1010 in contact with a printed circuit board (PCB) 500.
- PCB printed circuit board
- region corresponding to the metal member 810 of FIG. 8 may be integrally formed from the bus bar 1010 to vertically bend the central hole portion of the bus bar 1010.
- the ultracapacitor module according to the present invention is provided with a printed circuit board (PCB) 500 having a cell balancing function in a lower portion of the connection member 300 for fastening the neighboring ultracapacitors to separate them. No structure is needed.
- PCB printed circuit board
- the elastic member 600 is provided under the printed circuit board (PCB) 500 to have an elastic member such as a wave washer, such that the elastic member 600 is the printed circuit board (PCB) 500.
- the ultracapacitor module according to the present invention requires only one connection member, that is, a nut, for fastening between neighboring ultracapacitors when connecting a plurality of ultracapacitors. Accordingly, there is an effect of reducing the cost and the labor cost according to the saving of parts, and the life of the product is increased by improving the heat dissipation performance by reducing the resistance of the module.
