  The present invention relates to a battery cell fixing holder capable of connecting a plurality of batteries into one battery pack and a power battery pack thereof, and more particularly, to a battery cell mounting groove in a battery cell holder for fixing a battery cell. The present invention relates to a battery cell fixing holder and its power battery pack that are arbitrarily increased in number and connected to form a battery pack.

  A power battery pack refers to a battery device that provides mechanical power. Usually, this power battery pack needs to have a high voltage and a large current to operate the machine effectively as the only energy that operates the machine. The battery pack is a very important key because it is applied to devices that require relatively large driving power, such as an electric vehicle, an electric motorcycle, and an electric bicycle.

  A general battery pack usually uses a battery cell holder to weld a plurality of batteries (for example, nickel metal hydride batteries) to form a battery pack, and each battery pack usually uses 7 to 8 different batteries. Are connected to form a high voltage, high current battery pack.

  However, since the number of battery cell through holes used to fix the battery cells in the battery cell holder that normally fixes the battery is a fixed number, when connecting the batteries, the number of batteries in the battery pack is determined by the battery cell holder. It is necessary to match the number of through holes. For this reason, there is no flexibility of arbitrarily changing the number of batteries to be assembled. Similarly, if you want to assemble a battery pack with a larger or smaller number of batteries, you have to replace the battery cell holder with a larger or smaller number of battery cell through holes, which is rather inflexible and the number of batteries. It is not possible to make a change based on customization, and it is necessary to newly find the corresponding number of battery cell holders, and the utility is not high.

  Accordingly, the present invention proposes a battery cell fixing holder and its power battery pack that are effective in overcoming the above-mentioned problems with respect to the above-mentioned drawbacks of the prior art.

Based on the number of batteries, the number of battery cell mounting grooves required in the battery cell holder is determined. It is intended to provide a battery cell fixing holder and its power battery pack that can be developed and applied by customizing a module by arbitrarily combining them, and flexibility in use is enhanced.

  Another object of the present invention is to provide a battery cell fixing holder and its power battery pack that can be relatively improved in production efficiency by simplifying the structure and reducing the manufacturing cost.

  In order to achieve the above-mentioned object, a battery cell fixing holder provided by the present invention includes at least two mounting plates, provided with at least one battery cell mounting groove on the mounting plate, and at least one on both sides of the mounting plate. When the mounting recess is provided and the two mounting plates are aligned, one mounting groove is formed, a fixing plate is installed on the mounting groove, and a fixing fastener is passed through the mounting plate so that the mounting plate is The two mounting plates are connected by fixing on the fixing plate and fixing the fixing plate in the mounting groove.

  The power battery pack provided by the present invention includes two battery cell fixing holders, at least two battery cells are installed between the two battery cell fixing holders, and one end of each battery cell is one of the two battery cells. The battery pack is installed in the battery cell mounting groove of the fixed holder, and the other end of the battery cell is installed in the battery cell mounting groove of the other battery cell fixed holder to assemble the battery pack into a power battery pack.

  The present invention is used to fix battery cells, and a plurality of batteries can be connected to form one battery pack, and the number of required battery cell mounting grooves in the battery cell holder can be arbitrarily set based on the number of batteries. In combination, the module can be customized for development and application, increasing flexibility in use, simplifying the structure, reducing manufacturing costs, and relatively increasing production efficiency.
