Abstract
A test apparatus and corresponding method for simulating an internal cell short and initiating thermal runaway in a battery cell is disclosed whereby the cell is internally heated through rapid charge and discharge cycles at high currents. The magnitude of the selected current may be modulated to simulate a cell short with the desired power profile without unrealistically heating neighboring cells or interfering with the thermal environment of the cell within the module.
