Fire test of a battery electric vehicle (model year 2020) with an 80 kWh battery. At 850s after fire starts the battery got fully involved in the fire. This is visible by a rapid breakdown of the voltage (red line) from 400 V to zero and a constant increase of the temperature inside the battery from ambient temperature up to 400 °C.
