Problems solved by technology

Since a can-type secondary battery using a metal can as a container has a fixed shape, there are disadvantages that it limits the design of electronic products using a can-type secondary battery as a power source, and it is difficult to reduce the volume
In this case, the current does not flow into the resistor 1b of the fuse element 1, so the fuse element 1 does not work
Also, a space for placing the fuse element 1 is separately required within the protection circuit, and a program algorithm for controlling the operation of the fuse element 1 must be loaded in the microcontroller 3
Therefore, disadvantageously, the space efficiency of the protection circuit deteriorates, and the load on the microcontroller 3 increases

Abstract

A battery pack according to one embodiment of the present invention comprises: at least one battery cell; a pack case accommodating the battery cell and including a cooling hole penetratingly formed therein; a flow meter arranged outside the pack case and arranged adjacently to the cooling hole; and an opening / closing unit for opening / closing the cooling hole according to a temperature change inside the pack case.

Description

technical field [0001] The present invention relates to a battery pack with improved safety, and more particularly, the present invention relates to a battery pack configured to detect an increase in temperature in the battery pack exceeding a reference value, and then replace the battery Groups are isolated from the outside world and alerted to users so that they can become aware of abnormal conditions. [0002] This application claims priority from Korean Patent Application No. 10-2017-0173488 filed in Korea on December 15, 2017, the disclosure of which is incorporated herein by reference. Background technique [0003] As portable electronic products such as video cameras, cellular phones and portable PCs are more widely used, the importance of secondary batteries mainly used as their driving power sources is increasing. [0004] Unlike primary batteries that cannot be recharged, secondary batteries that can be charged and discharged are being used in applications such as...
