Abstract
The present disclosure relates to a battery pack with improved safety through high reliability of temperature measurement of a plurality of battery cells. To achieve the above-described object, the battery pack includes a plurality of battery cells, a temperature sensor configured to measure a temperature of at least one of the plurality of battery cells, a module case configured to receive the plurality of battery cells therein and including a recessed space in which the temperature sensor is disposed, and a holder inserted into the recessed space of the receiving portion. The holder has a size that is large enough to fill at least part of the recessed space and is configured to hold the temperature sensor.
Claims10
A battery pack, comprising:
- a plurality of cylindrical battery cells, each cylindrical battery cell being vertically arranged with a first terminal at a top end and a second terminal at a bottom end;
- a temperature sensor configured to measure a temperature of at least one of the plurality of cylindrical battery cells;
- a module case configured to receive the plurality of cylindrical battery cells therein, and including a recessed space defined between respective ones of the cylindrical battery cells and in which the temperature sensor is disposed;
- and
- a holder inserted into the recessed space, the holder having a size that is large enough to fill at least part of the recessed space and configured to hold the temperature sensor,
- wherein the holder has an insertion groove recessed along a vertical length of the holder, at least part of the temperature sensor is inserted and fixed into the insertion groove along a vertical length of the holder, and
- wherein the holder includes a notch defining a groove extending inward along a vertical length of the holder and configured to form a gap with the temperature sensor.
