Abstract
A device for heating a battery cell including an electrode assembly accommodated in a case and an electrode lead connected to the electrode assembly and having at least a portion disposed outside of the case includes a cell fixing portion in which at least one battery cell is disposed; and a heating unit configured to partially supply thermal energy to the battery cell, wherein the heating unit supplies thermal energy to the electrode lead disposed outside of the case.
Claims12
A device for heating a battery cell including an electrode assembly accommodated in a case and an electrode lead connected to the electrode assembly and having at least a portion disposed outside of the case, the device comprising:
- a cell fixing portion in which at least one battery cell is disposed;
- and
- a heating unit configured to supply thermal energy to the electrode lead,
- wherein the heating unit supplies thermal energy to the electrode lead disposed outside of the case, and
- wherein the heating unit continuously generates flames to supply thermal energy.
A device for heating a battery cell including an electrode assembly accommodated in a case and an electrode lead connected to the electrode assembly and having at least a portion disposed outside of the case, the device comprising:
- a cell fixing portion in which at least one battery cell is disposed;
- a heating unit configured to supply thermal energy to the electrode lead;
- and
- a blocking unit disposed between the case and the heating unit and configured to block thermal energy from being directly transferred to the case,
- wherein the electrode assembly receives thermal energy through the electrode lead.
A method of heating a battery cell, the method comprising:
- disposing a battery cell including an electrode assembly accommodated in a case and an electrode lead connected to the electrode assembly and having at least a portion disposed outside of the case on a cell fixing portion;
- and
- supplying thermal energy to the electrode lead,
- wherein the supplying the thermal energy includes heating the electrode lead disposed outside of the case using flames.
