The invention provides a self-rescue system for thermal runaway of new energy automobile, and a new energy automobile comprising the same. The self-rescue system comprises: a battery monitoring unit, which is used for monitoring the state data of a power battery pack, and outputting a thermal runaway signal when the state data represents that the power battery pack has a thermal runaway risk; a mounting part, which is used for mounting the power battery pack on a vehicle body, wherein the mounting part comprises a fracture execution part and a control part, and after receiving the thermal runaway signal, the control part controls the fracture execution part to disconnect the mounting part so as to allow the power battery pack to fall off from the vehicle body; and a moving trolley, which is fixed at the bottom of the power battery pack and is provided with an electric control unit and a driving mechanism, wherein the electric control unit controls the driving mechanism to drive the fallen power battery pack to move according to a received driving signal. According to the above scheme, the power battery pack can be separated from the vehicle body and transferred under the condition of thermal runaway of the vehicle, so the damage degree of the vehicle body is reduced, and the personal safety of personnel on the vehicle can also be ensured.
Description
technical field [0001] The present application relates to the technical field of new energy vehicle power battery system design, and specifically relates to a new energy vehicle thermal runaway self-rescue system and a new energy vehicle including the same. Background technique [0002] For new energy vehicles that use high-voltage batteries as power sources, their safety issues have attracted more and more attention. [0003] At present, once a new energy vehicle catches fire and spontaneously ignites, it can only wait for firefighters to come to the rescue. During the waiting process, the power battery may explode. Not only the fire vehicle itself may be severely burned and scrapped, but also, in some cases , When the fire vehicle is severely damaged, it is difficult to investigate the cause of the fire, and it is difficult to provide technical support for the subsequent research and development of new energy vehicles. Contents of the invention [0004] The present appl...
