"textContent": "The present disclosure relates to a method of detecting an abnormal operating condition of a battery system, which may lead to a thermal runaway. The battery system, which performs the detection method, comprises a battery pack including a plurality of battery cells and a cooling system including a pump for circulating a liquid coolant in a cooling circuit, a first heat exchange member integrated into the cooling circuit and thermally contacting the battery cells, and at least one pressure sensor adapted to detect a change in pressure inside the cooling circuit. A battery management system is connected to the pressure sensor and the pump and configured to perform a detection mode including the steps of: step a) detecting an initial pressure with the pressure sensor and switching off the pump for a specified time period, step b) after switching off the pump, capturing the pressure with the pressure sensor, and step c) determining a pressure difference between the initial pressure value and the captured pressure and, when the pressure difference exceeds a predetermined threshold, detecting an abnormal condition that could cause the occurrence of a thermal runaway of the battery pack.",
