Abstract

The invention relates to an electric car battery swap station power battery thermal runaway emergency disposal system. The system comprises a closed tank type battery shelf, a gas extinguisher, an electrical control device, a fume extractor and a fire-resistant rolling shutter door wherein the battery shelf is internally layered; each layer is divided into a plurality of zones; all the zones are physically partitioned through fireproof plates; each zone is internally provided with at least one power battery and internally provided with a power battery thermal runaway sensing device; the gas extinguisher communicates with all the zones through gas pipelines and nozzles independently; the electrical control device is in signal connection with the gas extinguisher and the power battery thermal runaway sensing devices; a blast capacity power device of the fume extractor is in signal connection with the electrical control device; in the normal state, the blast capacity power device operates with a low blast capacity, and the fume extractor is used as a radiating air flue; in the thermal runaway state, the blast capacity power device operates with the maximum blast capacity; and the fire-resistant rolling shutter door is in signal connection with the electrical control device.

Description

technical field [0001] The invention relates to an emergency treatment system and method for thermal runaway of a power battery in an electric vehicle charging and swapping station, and belongs to the technical field of fire-fighting facilities in a power battery charging and swapping station. Background technique [0002] The battery storage in the electric vehicle charging and swapping station is dense and the energy density is high. The power battery fire has the characteristics of high combustion temperature, high combustion intensity, fast combustion speed, a large amount of toxic and harmful gases, large differences in the combustion of batteries of different systems, and difficulty in fire fighting. Thermal runaway events such as fire and explosion occur, and the consequences are disastrous. Existing fire protection facilities for electric vehicle charging and swapping stations mainly include in-station water sprinkler systems, hand-held fire extinguishing equipment, ...
