Abstract: The present application discloses an automatic fire extinguishing system for an electric vehicle parking space, including a thermal runaway isolation system, and further including a detection system, a medium system, and a fire control access system. The detection system is installed inside a battery pack of an electric vehicle and performs fire monitoring inside the battery pack. One end of the fire control access system extends into a vehicle body of the electric vehicle and is joined to the inside of the battery pack, and the other end of the fire control access system extends out of the vehicle body of the electric vehicle and is communication with the medium system. The medium system is disposed outside an electric vehicle parking space. The fire control access system includes a transfer pipe and a quick insertion joint mechanism. Existing “afterward fire extinguishing” in the technical status in the background is resolved.

Abstract: The present invention discloses a battery pack charging system, comprising battery packs and a charging cabinet, a nitrogen replacement device is arranged inside the charging cabinet, the charging cabinet provides charging and nitrogen filling for the battery packs, wherein: there is a gas-filling protective device arranged between the nitrogen replacement device and the battery packs, and the gas-filling protective device is used to regulate the gas-filling flow of nitrogen automatically. Also disclosed is a charging method of the battery pack charging system.

Abstract: Disclosed in the present invention is a special container for battery transport, including a container body and a fire extinguishing system. The fire extinguishing system is used for extinguishing a fire in the container. The fire extinguishing system includes a connection device and a firefighting pipeline. The firefighting pipeline conveys a fire extinguishing agent into each container body and discharges the fire extinguishing agent from the container body. An end of the connection device is fixedly connected to a container body wall of the container body. The connection device communicates the firefighting pipeline between two vertically adjacent container bodies. Beneficial effects: A series fire extinguishing mode among each column of stacked containers is implemented through the innovation of a connection device.

Abstract: Disclosed in the present invention is a prevention and control method of nitrogen protection and multi-region level-by-level detection for an energy storage power station. The prevention and control method of nitrogen protection and multi-region level-by-level detection for an energy storage power station includes two modes: a normal operating mode and an abnormal mode. In the two modes, fire extinguishing measures of different levels are adopted for a battery pack, a battery cluster, a battery compartment, and a device compartment with reference to early warning thresholds of different levels. Further disclosed is a prevention and control system of nitrogen protection and multi-region level-by-level detection for an energy storage power station.

Abstract: The present invention discloses a fire extinguishing system for a battery pack, including a detection control apparatus, a fire suppression apparatus, and a hydrant water extinguishing apparatus. The detection control apparatus is disposed inside or outside a battery pack. The fire suppression apparatus and the hydrant water extinguishing apparatus are disposed outside the battery pack. The detection control apparatus is connected to the fire suppression apparatus. The hydrant water extinguishing apparatus is connected to the fire suppression apparatus. Beneficial effects: It is ensured that initial fire can be suppressed and later reignition can be resolved, so that fire extinguishing is adequate. Fire is directly extinguished at a core position inside the battery pack. An exhaust filter device gains valuable time after initial fire extinguishing.
