Explosion-proof distance of energy storage power station

Do container type lithium-ion battery energy storage stations cause gas explosions?

Here, experimental and numerical studies on the gas explosion hazards of container type lithium-ion battery energy storage station are carried out. In the experiment, the LiFePO4 battery module of 8.8kWh was overcharged to thermal runaway in a real energy storage container, and the combustible gases were ignited to trigger an explosion.

What happens if the stored energy capacity exceeds the limit?

Where the stored energy capacity or separation distance of the unit exceed the limit, it shall be subjected to the fire and explosion testing specified under UL 9540A and together with the NFPA 855 Hazard Mitigation Analysis report to be submitted to SCDF for approval.

How is combustion rate distributed in energy storage container during explosion?

Variation process of combustion rate in energy storage container during explosion. Due to the numerous battery modules installed in the container, the flame was limited in the middle aisle and on the top of the container. Fig. 7 a showed the combustion rate distribution at 0.24 second.

Where should the energy storage system be located?

All Energy Storage System installations shall be located at the same storey as the fire engine accessway/ fire engine access road. c. The allowable Maximum Stored Energy for the various battery technologies in each compartment shall be as listed in Table 10.3.1. a It shall refer to an aggregated stored energy capacity per compartment.
