Are battery energy storage systems safe?

Whether attached to solar power systems or used as a backup generator, battery energy storage systems (BESS) are growing in popularity for homeowners in numerous states. These units may provide safer, cleaner backup power during outages. Like lithium-ion batteries generally, residential BESS may catch fire or even explode.

What happens if a battery energy storage system is damaged?

Battery Energy Storage System accidents often incur severe losses in the form of human health and safety, damage to the property and energy production losses.

What are the hazards associated with a battery?

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.

Is battery storage a bad policy?

"Simply put, it is not just a bad policy, but a dangerous one, and the city is literally playing with fire by allowing this to happen." Holden is talking about proposals to build more battery energy storage system (Bess) centres - large-scale power storage sites based on the same lithium-ion batteries that are used in laptops and electric cars.

Can residential battery energy storage systems catch fire?

Like lithium-ion batteries generally, residential BESS may catch fire or even explode. BESS operating software may be a target for cyberattacks which could, in turn, heighten property or liability risks for homeowners. Residential battery energy storage systems (BESS) can serve two overarching purposes for homeowners.

How to reduce the safety risk associated with large battery systems?

To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
