A battery cell (1) including a system (10) for testing the cell by creating at least one effect of an internal short circuit within the cell (1), the cell comprising
- at least one cathode,
- at least one anode,
- at least one sensor (3), and
- at least one conductive heating element (2) having at least one resistive heat element (5),
- wherein at least the resistive heat element (5) is within the cell (1) for simulating an internal short circuit.
A method (100) for testing a battery cell (1) by creating at least one internal short circuit within the cell (1), the cell comprising at least one cathode, at least one anode, at least one sensor (3), and at least one conductive heating element (2) having at least one resistive heat element (5), the method comprising the following steps:
- a) assembling (101) the resistive heat element (5) within the cell (1),
- b) inputting (102) internal short power at the resistive heat element (5), and
- c) determining (103) the state of the cell (1).
