Claims11
A battery module, comprising:
- a plurality of battery cells stacked in one direction;
- and
- an end plate assembly covering an outermost battery cell disposed on the outermost among the plurality of battery cells,
- wherein the end plate assembly includes at least one thermistor for measuring a temperature of the outermost battery cell,
- wherein the end plate assembly is disposed to oppose a wide surface of the outermost battery cell,
- wherein the end plate assembly includes:
- a first plate disposed on an outermost side;
- and
- a second plate disposed between the first plate and the outermost battery cell and includes the at least one thermistor on one surface facing the outermost battery cell,
- wherein the one surface is disposed to oppose the wide surface of the battery cell, and
- wherein the first plate and the second plate are manufactured in the form of a sandwich panel,
- wherein the at least one thermistor includes:
- a first thermistor in contact with a first region of the outermost battery cell;
- and
- a second thermistor in contact with a second region of the outermost battery cell,
- wherein the first region has a highest average temperature in the outermost battery cell and is adjacent to an upper corner portion of the outermost battery cell and a busbar assembly electrically connected to the plurality of battery cells, and the second region has a lowest average temperature in the outermost battery cell.
