Disclosed herein is an energy storage module, including: upper and lower cases each having elastic bodies provide at both side parts thereof; a capacitor cell inserted within the upper case and the lower case and having anode electrodes and cathode electrodes extended at both side parts thereof; and bus bars inserted between the anode terminals and between the cathode terminals of the capacitor cell. According to the present invention, the module can be manufactured in a comparative simple constitution, and an electric short circuit between anode and cathode terminals can be prevented when swelling occurs due to repetitive charging and discharging of capacitor cells.
摘要:
An energy storage device includes a plurality of unit cells stacked therein, each of the unit cells including a cell body, a positive terminal disposed at one side of the cell body, and a negative terminal disposed in the cell body to form a constant rotation angle with the positive terminal with reference to a center of the cell body, wherein the plurality of cell units are stacked in such a manner that another unit cell is rotated as much as the constant rotation angle with reference to one unit cell. Temperature distribution, that is, heat distribution in the energy storage device can be kept even, and heat transmission efficiency between the terminals and the external air can be improved and thus cooling efficiency can be improved. Also, a resistance value is reduced by improving a cooling function so that performance and reliability of a product can be improved.

Disclosed herein is a lead unit of an energy storage device including a lead frame for fixing withdrawal electrodes of the energy storage device, including: an output terminal unit formed on an upper portion of the lead frame; a lead unit formed to extend from the output terminal unit to a lower portion of the lead frame and allowing end portions of the withdrawal electrodes to be inserted therein; and an expanding unit formed at an end portion of the lead unit and being brought into contact with the withdrawal electrodes in a compressed manner.The fabrication process can be simplified compared with the existing welding method, and a contact area between the withdrawal electrodes and the lead unit can be increased to thus reduce contact resistance.
摘要:
Disclosed herein is an energy storage module including a first energy container, a second energy container that is connected to the first energy container in parallel, and a switching control unit that senses the energy containers corresponding to predetermined deterioration conditions among the first and second energy containers to selectively open the energy containers corresponding to deterioration conditions so as to selectively charge/discharge the energy containers, whereby the deterioration can be minimized without stopping the overall energy storage module.
