Description

Mass charging/discharging device for pouch-type battery cells without terminals}

The present invention relates to a charging and discharging device for pouch-type battery cells without a terminal, and in particular, to a mass charging and discharging device that is configured to charge and discharge battery cells in large quantities and enables mass production of battery cells.

Recently, as technology development and demand for mobile devices increase, the demand for pouch-type battery cells as an energy source is rapidly increasing.

Specifically, the pouch-type battery cell may be used in the form of a single battery cell, or in the form of a battery module in which multiple unit cells are electrically connected, depending on the type of external device in which it is used.

For example, small devices such as mobile phones can operate for a certain period of time with the output and capacity of one battery cell, while laptop computers, portable DVDs, small PCs (personal computers), electric vehicles, and hybrid electric vehicles can operate for a certain period of time with the output and capacity of one battery cell. Medium or large devices such as automobiles require the use of a battery module containing multiple battery cells due to issues with output and capacity. The battery module is a core pack that connects multiple unit cells arranged in series and/or parallel. It is manufactured by connecting a protection circuit, etc.

In addition, when using prismatic or pouch-type battery cells as unit cells, they can be easily manufactured by stacking them so that the wide surfaces face each other and then connecting the electrode terminals with a connecting member such as a bus bar.

Therefore, when manufacturing a three-dimensional battery module with a hexahedral structure, a square or pouch-shaped battery is advantageous as a unit cell.

Conventionally, nickel cadmium batteries or hydrogen ion batteries were used as pouch-type battery cells, but recently, lithium-ion batteries and lithium polymer batteries with high energy density and high charge/discharge potential have been widely used, and these pouch-type battery cells are as described above.
