3 Terms and definitions

4 Small electrochemical energy storage power station site selection requirements

4.1 Site selection should not be close to areas with potential fire or explosion hazards. When adjacent to a building that is at risk of explosion or fire, it complies with the provisions of the current national standard GB 50058 "Design Specification for Explosive Hazardous Environmental Power Equipment".

4.2 It is not advisable to choose at the intersection of urban trunk roads and busy traffic sections.

4.3 Small electrochemical energy storage power stations should be set up independently, not less than 10 meters away from the surrounding buildings, and not far from important public buildings.

Less than 25 meters.

4.4 It should not be located in a place with dusty or corrosive gas. When it cannot be far away, it should not be located on the leeward side where the pollution source prevails in the wind direction.

4.5 It should not be located in a place where water may accumulate.

4.6 The design elevation of the site of a small electrochemical energy storage power station should be higher than the flood level with a frequency of 2% or the highest water level in the history.

When the ground design elevation cannot meet the requirements, a reliable water retaining facility or the main equipment base and the indoor floor elevation of the production building should be set.

Higher than the requirement.

4.7 Small electrochemical energy storage power stations should be installed in the area covered by the municipal fire protection pipe network.

5 Station fire protection requirements

5.1 Station buildings should be made of non-combustible materials.

5.2 The battery storage room and the electrical control room in the station should be set independently. If it cannot be set independently, the fire resistance limit should be less than 2h.

Separation of materials, it is not advisable to open the door or open the window on the partition material.

5.3 The battery storage area of the station should be equipped with an explosion-proof accident emergency natural ventilation device, and the ventilation area should be no less than the construction area.

5%; the natural ventilation device should be linked with the fire protection system, and the action time is less than 30s.

5.4 A video surveillance system should be set up in the station, and the video surveillance system should be able to clearly observe the battery cabinet.

5.5 The station building shall be in accordance with the "Severe Dangerous Level" configuration in accordance with the "Code for Design of Fire Extinguishers for Buildings" GB 50140 for fire extinguishers, clean gas fire extinguishers should be used.

5.6 Independent fire power supply should be provided.

5.7 An obvious power cut-off device should be provided. In case of fire, the power supply should be cut off immediately.

5.8 Cable fire prevention and prevention of flame retardation shall comply with the current national standard "Code for Design of Power Engineering Cables" GB 50217-2007 Chapter 7 Relevant regulations.

5.9 The station building should be equipped with an emergency lighting system.

6 Energy storage unit safety requirements

7 Active lithium battery fire suppression device requirements

7.1 Active lithium battery fire suppression device should use flammable gas detector to detect battery thermal runaway, each fireproof single of the battery rack Yuan should set up a lot of flammable gas detectors.

7.2 Active lithium battery fire suppression device should be arranged in each fireproof unit of the battery cabinet, gas fire extinguishing should be adopted Agent. Within 10 s after the alarm of the flammable gas detector, the fire extinguishing concentration in the battery cabinet should meet the design requirements.

7.3 Active lithium battery fire suppression device power supply should be set independently.

7.4 Active lithium battery fire suppression device should be equipped with manual/automatic switching device, which is arranged in the station room for easy operation position.

7.5 Active lithium battery fire suppression device should have sound and light alarm function.

7.6 Active lithium battery fire suppression device should be linked with the control center of the site construction unit.
