Study Notes
Energy Storage Systems (ESS)
- A battery or group of batteries assembled to store energy for later electrical energy supply
- Types of ESS: walk-in container system, outdoor cabinet, indoor facility (residential, commercial, public utility), large and small vehicle batteries
Electric Vehicle (EV)
- An automobile, e-scooter, e-bike, or other vehicle with an electric motor fully or partially powered by batteries
Thermal Runaway
- A phenomenon where a lithium-ion cell enters an uncontrollable, self-heating state
- Risks associated with thermal runaway: dispersion of gases, ejection of shrapnel and/or particulates, fire
Background
- Increased use of lithium-ion batteries (LIBs) adds concerns for firefighter safety and incident mitigation
- LIBs are used in various consumer products, from small devices to large-scale power grid support
- Fires involving LIBs are increasing, resulting in fatalities, and can intensify existing fires
Hazards
- LIBs may rupture and disperse toxic, flammable gases, and/or explode violently due to:
- Thermal conditions (hot or cold, temperature changes)
- Physical damage (impact, crush, pierce)
- Electrical issues (over-charging, forced discharge, internal defects, internal short circuiting)
- Drying after being submerged in water (especially saltwater)
Safety Precautions
- Discard LIBs submerged in saltwater immediately
- Be cautious of re-ignition, which can occur minutes, hours, or even days after visible fire has been extinguished
- Never compromise the container to allow water to enter the case
