The invention provides a new energy automobile thermal runaway self-rescue system and a new energy automobile comprising the same, and relates to the field of new energy automobiles. The thermal runaway self-rescue system of the new energy automobile comprises a power control module, an alarm module, a power lithium battery module, a low-voltage lead-acid battery module, a power switching circuit, a detection sensor arranged inside the power lithium battery module, a detection sensor arranged outside the power lithium battery module and a battery management system connected with the components. The system can detect the gas, temperature and impedance in the power battery module and the temperature and pressure outside the power battery module in real time, and analyzes the thermal runaway condition in the power battery module from multiple angles, so that the reliability and sensitivity of thermal runaway early warning can be effectively improved, and the reliability and reliability of thermal runaway early warning are improved. The battery can be detected in the early and middle stages of thermal runaway, the battery problem can be detected before thermal runaway, and the safety of the battery is effectively improved.
