Background technology

[2]

In recent years, the charge/discharge batteries available for the wireless mobile devices and is widely used as an energy source. In addition, the secondary battery using fossil fuels conventional gasoline vehicles, such as the air pollution such as diesel vehicles as being present for electric vehicle (EV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (HEV Plug-In) is getting attention as a member of the power of.

[3]

They have a small mobile devices devices per one or two used a few battery cells on the contrary, this car such as the need for a high-output medium device, due to the large number of battery cells electrically connected battery module is used.

[4]

Battery modules are manufactured with a small size and weight, if possible, it is desirable that, in contrast to the high density can be capacity weight small alluvial with hexagonal cells, pouch-type battery such as the medium to large battery modules are being used primarily as a battery cell. In particular, the absence of aluminum laminate sheet to use as an external pouch-type battery weight due to this point, such as a small manufacturing costs lower recently has attracted a lot of attention.

Challenges in the Sudan

[12]

This is due to the invention of the absence, the interconnection of cells and modules of the PCB (printed circuit board) and battery electrode terminals of a cell coupled to the bus bars, as the absence of reciprocal linking (a) revenge of the copper (copper line) FFC (Flexible Flat Cable) is made up of the main cable; (B) above, at least one of the main cable, copper wire, electrically connected to a branch from the main cable structure (分 枝) voltage of battery cells, and sensing is connected to the bus bars for multiple terminals; (C) above is only part of the work of the main cable side PCB, electrical and mechanical coupled with connecting part; And (d) above, at least one of the main cable of copper, in the form of sharing, connecting and adjoining the main cable has been at least one branch from temperature sensing part; and (b) to (d) more than two of the FFC (Flexible Flat Cable) will be made.

[13]

In other words, this invention due to the absence of the interconnection wiring structure of each voltage sensing, temperature sensing, and connect the connector on the PCB extends from the main cable and all the structures that make up the basin bar, wiring structure compact.

[14]

In particular, an extremely thin, light weight and thickness of the main cable to the FFC consist of the absence of interconnection, there is a separate space for mounting and the mounting screw or bolt their absence, for example, rivet and combined arms (arm) are not required. As an example, the main part of the cell or a battery module if the cable insulation tape case attached by interconnection by the absence, combined with the excellent space utilisation locked structure due to the deletion of the part will can achieve.

[15]

In addition, the FFC connector on the PCB formed electrical and Mechanical Department of the above, so that coupled with the connecting rod can be reminded of the FFC consist of a connecting part of the main cable to share all of the copper wire extends from the main cable can be in the form of. This is also the aforesaid in the absence of interconnection of spatial advantage, as is required in replacing the components can save by leaps and bounds.

[16]
