Battery cabinet energy storage cabinet danger

A pilot-stage lithium-ion (Li-ion) battery energy storage cabinet beneath the Minquan Bridge in Neihu District, Taipei City, caught fire in July 2020 and took firefighters more than three hours to bring under control.

Battery cabinet fire propagation prevention design: If an energy storage system is not compartmentalized, a thermal runaway event in a single battery is extremely likely to spread to neighboring cabinets, causing a massive fire in the entire container or even a sudden explosion.

To ensure power grid stability, demand for large stationary energy storage systems (battery cabinets) has increased rapidly. However, several fire and explosion incidents in connection with energy storage systems have made people realize that the road to renewable energy is not as smooth as one would hope, and that more challenges likely await.

Making energy storage systems safer, ensuring safety in product design and production to avoid similar incidents, and adopting damage control and loss reduction mechanisms in the event of a disaster are all aspects that need to be considered and improved upon.

The interior of the cabinet is lined with heat-resistant ceramic material (temperature resistance: 1260 ºC), which can effectively prevent the fires from spreading and burning while also ensuring the safety of other cabinets and the normal operation of the entire energy storage system.

These hazards can be associated with the chemicals used in the manufacture of battery cells, stored electrical energy, and hazards created during thermal runaway, (see below) which can include fire, explosions, and chemical byproducts.
