While it’s important to understand how dangerous a battery energy storage system can be when it goes bad, the hazards and exposures can vary depending on how the system is set up. Trudeau uses the example of a hospital replacing part of its uninterruptible power source with a standard 20-foot container of lithium-ion batteries.
However, despite the glow of opportunity, it is important that the safety risks posed by batteries are effectively managed. Battery power has been around for a long time. The risks inherent in the production, storage, use and disposal of batteries are not new.
But intermittency in sectors like wind and solar power — a disruption caused by the inconsistency of the weather — has made them less reliable as forms of energy. These limitations, however, have been primarily offset by the use of Battery Energy Storage Systems (BESS), a means of storing the energy produced until it is needed.
Myth #4: Damaged batteries are not a threat unless they are on fire. Though the danger may not be immediately apparent, defects in battery energy storage systems can be active threats in the spaces in which they are used. Defects in the chemical makeup of the battery modules may make them prone to overheating, causing a chemical reaction.
These incidents represent a 1 to 2 percent failure rate across the 12.5 GWh of lithium-ion battery energy storage worldwide. To better understand and bolster the safety of lithium-ion battery storage systems, EPRI and 16 member utilities launched the Battery Storage Fire Prevention and Mitigation initiative in 2019.
Battery power has been around for a long time. The risks inherent in the production, storage, use and disposal of batteries are not new. However, the way we use batteries is rapidly evolving, which brings these risks into sharp focus.

THR is obtained by integrating the measured HRR (with the burner contribution subtracted) over the complete test time. Fig. 2b shows the energy ratio, that is how much energy is produced by the burning battery, compared to the amount of nominal electrical energy capacity a fully charged battery can deliver to an external circuit. The energy ratio is therefore a comparison between …
Batteries should be sourced only from reputable suppliers and should be stored safely. Careful consideration should be given to mitigating the risks of storage in communal or enclosed areas, or near to escape routes. Battery damage and disposal can pose a significant risk. Where the battery is damaged, it can overheat and catch fire without ...
