Battery module, battery pack including such battery module, and vehicle including such battery pack
Disclosed is a battery module, which includes a battery cell assembly having a plurality of battery cells which are stacked one another, an interconnection board mounted to at least one side of the battery cell assembly to electrically connect the plurality of battery cells, a temperature sensor mounting groove provided at the interconnection board so that a temperature sensor for measuring a temperature of the battery cell assembly passes therethrough, and an assembling error preventer provided at a bottom of the temperature sensor mounting groove to prevent the temperature sensor from interfacing with a facing battery cell which faces the temperature sensor when the temperature sensor passes through the temperature sensor mounting groove.
1. A battery module, comprising:
a battery cell assembly including a plurality of battery cells which are stacked one another;
an interconnection board mounted to at least one side of the battery cell assembly to electrically connect the plurality of battery cells;
a temperature sensor mounting groove provided at the interconnection board so that a temperature sensor for measuring a temperature of the battery cell assembly passes therethrough; and
an assembling error preventer provided at a bottom of the temperature sensor mounting groove to prevent the temperature sensor from interference with a facing battery cell which faces the temperature sensor when the temperature sensor passes through the temperature sensor mounting groove by pushing away an end of a pouch terrace of the facing battery cell until the end of the pouch terrace is rested on a midsection of the assembling error preventer.
2. The battery module according to claim 1 , wherein the assembling error preventer includes:
a preventer body configured to protrude from the bottom of the interconnection board toward the plurality of battery cells and having a sensor passing hole communicating with the temperature sensor mounting groove so that the temperature sensor passes therethrough; and
a sensor assembling guider provided at the preventer body to push the facing battery cell, which faces the sensor assembling guider when the interconnection board is mounted, to the outside of the sensor passing hole.
3. The battery module according to claim 2 , wherein the sensor assembling guider is inclined toward the facing battery cell.
4. The battery module according to claim 3 , wherein when the interconnection board is mounted, the facing battery cell which faces the sensor assembling guider slides above the sensor assembling guider in contact with the sensor assembling guider.
5. The battery module according to claim 3 , wherein the sensor assembling guider is formed at an outer surface of the preventer body.
6. The battery module according to claim 5 , wherein an outer diameter of the preventer body is gradually decreased toward the battery cell assembly.
7. The battery module according to claim 1 , wherein the assembling error preventer is integrally formed with the interconnection board.
8. A battery pack, comprising:
at least one battery module defined in claim 1 ; and
a pack case configured to package the at least one battery module.
9. A vehicle, comprising a battery pack defined in claim 8 .
10. A battery module, comprising:
a battery cell assembly including a plurality of battery cells which are stacked one another;
an interconnection board mounted to at least one side of the battery cell assembly to electrically connect the plurality of battery cells;
a temperature sensor mounting groove provided at the interconnection board so that a temperature sensor for measuring a temperature of the battery cell assembly passes therethrough; and
an assembling error preventer provided at a bottom of the temperature sensor mounting groove to prevent the temperature sensor from interference with a facing battery cell which faces the temperature sensor when the temperature sensor passes through the temperature sensor mounting groove,
wherein the assembling error preventer includes:
a preventer body configured to protrude from the bottom of the interconnection board toward the plurality of battery cells and having a sensor passing hole communicating with the temperature sensor mounting groove so that the temperature sensor passes therethrough; and
a sensor assembling guider provided at the preventer body to push the facing battery cell, which faces the sensor assembling guider when the interconnection board is mounted, to the outside of the sensor passing hole.
11. The battery module according to claim 10 , wherein the sensor assembling guider is inclined toward the facing battery cell.
12. The battery module according to claim 11 , wherein when the interconnection board is mounted, the facing battery cell which faces the sensor assembling guider slides above the sensor assembling guider in contact with the sensor assembling guider.
13. The battery module according to claim 11 , wherein the sensor assembling guider is formed at an outer surface of the preventer body.
14. The battery module according to claim 13 , wherein an outer diameter of the preventer body is gradually decreased toward the battery cell assembly.
15. The battery module according to claim 10 , wherein the assembling error preventer is integrally formed with the interconnection board.
16. A battery pack, comprising:
at least one battery module defined in claim 10 ; and
a pack case configured to package the at least one battery module.
17. A vehicle, comprising a battery pack defined in claim 16 .
