Huawei outdoor power emergency use scenarios

The test showed that Huawei's ESS (container A) delayed fire ignition for seven hours in extreme scenarios, even as the number of thermal runaway cells increased. Such delayed propagation would allow emergency personnel time for early intervention, mitigating risks for personnel and property.

If a Huawei energy storage system (ESS) emits smoke or catches fire, household members should not dispose of the ESS by themselves. Follow the following steps: If batteries emit smoke or catch fires, notify all household members to evacuate immediately.

The manufacturer also reported a slow fault progression as one of the product's key safety features. The test showed that Huawei's ESS (container A) delayed fire ignition for seven hours in extreme scenarios, even as the number of thermal runaway cells increased.

In real-world safety incidents, it is often a single cell that leads to the release of combustible gases in the container, potentially resulting in fire or explosion. However, in Huawei's Smart String & Grid Forming ESS (container A), thermal runaway was initiated in 12 cells without an incident.

Move the removed batteries to a safe place (an open and safe outdoor place is recommended), and then place the batteries in the fire sand box or salt water. If a Huawei energy storage system (ESS) emits smoke or catches fire, household members should not dispose of the ESS by themselves. Follow the following steps:

Post-test disassembly confirmed the integrity of the ESS body, fire-resistant layer, and internal battery packs, Huawei said. The manufacturer also reported a slow fault progression as one of the product's key safety features.
