Problems solved by technology

[0004] However, if multiple secondary batteries are connected in series and used for a long time, the voltages of the secondary batteries may differ from each other
In addition, increasing the total capacity of the secondary battery may be more important than increasing the output voltage of the secondary battery

Abstract

A battery module according to an embodiment of the present invention comprises: a base plate; a plurality of battery cells arranged on the base plate; a plurality of sockets electrically connected toelectrode leads of the battery cells; and a plurality of connecting bars inserted into some of the plurality of sockets so as to connect the plurality of battery cells in series or in a combination manner of series and parallel.

Description

technical field [0001] The present disclosure relates to a battery module, and more particularly, to a battery module having a structure capable of easily changing a connection mode between a plurality of battery cells. [0002] This application claims priority from Korean Patent Application No. 10-2017-0128194 filed in Korea on September 29, 2017, the disclosure of which is incorporated herein by reference. Background technique [0003] Recently, with the technical development of electronic equipment and electric vehicles, the capacity of the secondary battery needs to be increased, and a larger output voltage is also required. Therefore, in order to obtain a sufficient output voltage by using a secondary battery, a plurality of secondary batteries may be connected in series. [0004] However, if a plurality of secondary batteries are connected in series and used for a long time, the voltages of the secondary batteries may differ from each other. In addition, increasing t...
