Abstract

The present invention relates to a battery module and a battery pack comprising the same and, more specifically, to: a battery module comprising bus bars having the same shape and connected to positive electrode (+) terminals and negative electrode (-) terminals of a plurality of battery cells; and a battery pack having, at the same side parts of a plurality of battery modules, a bus bar connection part for providing an electrical connection between modules through the bus bars.

Description

technical field [0001] The present invention relates to a battery module and a battery pack including the battery module, and more particularly, to a battery module including positive (+ ) pole terminal and a negative (-) pole terminal, and relates to a battery pack provided with a bus bar connection portion passing through the same side surface portion of each of a plurality of battery modules The bus bars in the electrical connection and junction modules. Background technique [0002] As a unit battery cell constituting a battery pack, lithium secondary batteries are flexible, thus have a relatively free shape, are light in weight, and also have excellent safety. Therefore, lithium secondary batteries are used as portable electronic devices (such as mobile phones, Camcorders and notebook computers) have increased demand for power supplies, and secondary batteries are widely used in large and medium-sized appliances such as automobiles, power storage devices, and the like....
