Study Notes
Electric Vehicles (EVs)
- Defined as vehicles powered by an electric motor that draws electricity from a battery, which can be charged from an external source
- Includes both all-electric vehicles and plug-in hybrid vehicles
Types of Electric Vehicles
- Extended Range EV: has a small internal combustion engine to generate additional electric power
- Plug-in Hybrid Vehicle: battery is recharged by regenerative braking or a plug-in charging station
Thermal Runaway
- A phenomenon in which a lithium-ion cell enters an uncontrollable, self-heating state
- Can result in dispersion of gases, ejection of shrapnel and particulates, fire, and deflagration
Energy Storage Systems (ESS)
- A battery or group of batteries assembled to store energy to supply electrical energy at a later time
- Four types: walk-in container systems, outdoor cabinet, indoor facility, and large and small vehicle batteries
Hazards of Lithium-Ion Batteries (LIBs)
- May rupture and disperse toxic flammable gases and explode violently when ignited
- Hazards include thermal conditions, physical damage, and electrical issues
- Produce flammable and toxic gases, including hydrogen fluoride and phosphorus pentafluoride
- Can re-ignite unexpectedly, even after all visible fire has been extinguished
Safety Considerations for Responders
- Always wear full PPE, including SCBA, when working in a controlled area
- Ensure vehicle is in park and turned off, and chock the wheels
- Avoid touching the service plug, which poses a high risk of electrocution
- Be aware of multiple classes of fires, including Class A, B, C, and D
- Risks for responders include electrical shock, high temperatures, toxic fumes, lithium burns, toxic runoff, and re-ignition
