Abstract: In order to improve the efficiency of pure electric vehicle fire fighting and to ensure the safety of fire and rescue personnel, on the basis of the case analysis, the fire causes and fire characteristics of pure electric vehicles are summarized. According to the needs of basic fire fighting and rescue, a modular new energy vehicle fire fighting robot is designed, and its structure and working principle are briefly summarized. Based on the current research progress of fire rescue technology, this paper proposes a fighting tactic of applying chassis fire extinguishing robot to improve the efficiency of fire extinguishing agent, which is proved to have certain guiding significance for fire fighting of pure electric vehicle fire.

Key words: fire extinguishing robot, battery electric vehicle, lithium-ion battery, fire rescue
