A fixing device for fixing a plurality of energy storage cells arranged in parallel to each other includes a body having a hole formed through an upper surface and a lower surface thereof to accommodate a part of at least one energy storage cell; a first coupling protrusion and a first accommodation portion formed at a first side surface of the body to be spaced apart in opposite directions by the same distance from a center of the first side surface, the first coupling protrusion and the first accommodation portion being shaped to engage with each other; and a second coupling protrusion and a second accommodation portion formed at a second side surface of the body, which is opposite to the first side surface, to be spaced apart in opposite directions by the same distance from a center of the second side surface.

Fixing device for fixing plurality of energy storage cells, and energy storage module using same

An energy storage device includes: an external terminal having any one of positive and negative polarities and including a protrusion and a first terminal; a case having a polarity opposite to the external terminal and including an extension; a substrate disposed to surround an outer circumference of the protrusion of the external terminal through a hole formed at a center thereof; and a connection member located at an upper surface of the substrate and coupled to the first terminal of the external terminal, wherein the first terminal and the substrate are connected by means of the connection member, and the extension is connected to the substrate. Since positive and negative electrodes of the energy storage device are electrically connected to a substrate having a cell balancing function without a harness or any other member, it is possible to improve the economic feasibility and productivity of the energy storage device module.

Energy storage device

An energy storage device having improved heat-dissipating includes a cell assembly formed by connecting at least two cylindrical energy storage cells in series, a case having an accommodation portion shaped corresponding to an outer surface of the energy storage cells to accommodate the cell assembly, and a heat-dissipating pad installed between an outer surface of the energy storage cells of the cell assembly and an inner surface of the accommodation portion, wherein the case includes at least two case blocks, and wherein the accommodation portion is formed by coupling the case blocks.

Energy storage device having improved heat-dissipation characteristic

An ultra capacitor module includes a first ultra capacitor having a first polar terminal provided with a screw thread A formed on an outer peripheral surface, a second ultra capacitor having a second polar terminal provided with a screw thread A formed on an outer peripheral surface, and a connecting member having a screw hole B formed corresponding to the screw thread A on an inner peripheral surface through which the first polar terminal is inserted from one side and the second polar terminal is inserted from the other side to connect the first and second ultra capacitors in series and having a gas emission hole formed from a center to an outer surface.
