Abstract

Abstract: To investigate the fire hazards and combustion patterns of children's electric toy vehicle, combustion performance experiments were conducted on vehicle components and the complete vehicle. The combustion performance experiment of non-metallic materials used in the vehicle were tested, including oxygen index, ignition temperature, ignition time, heat release rate, smoke production, and toxic gas; the heat release rate, total heat release amount, and combustion temperature of the entire vehicle combustion were tested, too. The experimental results show this children's electric toy vehicle has a high fire risk, with an oxygen index of 18.8% for the front cover and body cover, and the ignition temperature is 283 ℃; after a short circuit in the vehicle wire for 15 seconds, an open fire appeared, and the peak heat release rate of the complete vehicle was 755.012 kW, with a total heat release of 192.50 MJ. Through this experimental study, the fire hazard analysis process of similar independent power supply equipment is summarized, which provides technical support for the fire investigation of related equipment.
