Does Huawei Digital Power's Smart string & grid forming energy storage system pass an ignition test?

Huawei Digital Power’s Smart String & Grid Forming Energy Storage System (ESS) has successfully passed an extreme ignition test in the presence of customers and Norway-headquartered independent assurance and risk management provider DNV.

How do you dispose of a Huawei energy storage system?

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:

How many Bess units did Huawei use in a fire test?

In its ignition test, Huawei used four utility-scale BESS units. This was previously done by Sungrow, which in November 2024 conducted a fire test on 20 MWh of BESS. The exercise involved four liquid-cooled 5 MWh Powertitan 2.0 storage systems and came with a price tag of $4.2 million.

What if a Huawei energy storage system emits smoke or catches fire?

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.

How safe is Huawei's ESS (container a)?

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.

What is a thermal runaway in Huawei ESS (container a)?

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.
