? 1-5 Why is this course important to you as an emergency responder?
1-6 How familiar are you with hybrid electric vehicles and electric vehicles?
Differentiate between myths and reality. Terminal Objective ● Define HEV (hybrid electric vehicle), PHEV (plug-in hybrid electric vehicle) and EV (electric vehicle). ● List common myths related to EV safety. ● List two (2) actual safety concerns. Enabling Objectives 1-7 Module 1 Objectives
Hybrid Electric Vehicle Hybrid and Electric Vehicles are just another fad… Myth or Reality? 1-8 MYTH
Hybrid Electric Vehicle Hybrid and Electric Vehicles are just another fad… 1-9 ●HEV/EVs are growing in popularity. ●They are proven reliable. ●Goal is 1 million EVs on the road by 2015. ●Interest is at an all time high.
Hybrid Electric Vehicle Myth or Reality? Hybrid and electric vehicles may move unexpectedly at an emergency scene. 1-10 Reality
Hybrid Electric Vehicle Hybrid and electric vehicles may move unexpectedly at an emergency scene. 1-11 ●Unexpected movement is always a concern with electric and conventional vehicles. ●Unlike conventional vehicles, Hybrid and Electric vehicles may not produce engine noise, but could move silently without warning on their own power.
Hybrid Electric Vehicle Myth or Reality? At first glance, it may be difficult to distinguish between a conventional vehicle and a hybrid or electric vehicle of the same model. 1-12 Reality
Hybrid Electric Vehicle At first glance, it may be difficult to distinguish between a conventional vehicle and a hybrid or electric vehicle of the same model. 1-13 ●Most look like conventionally powered models. ●Responders will need to recognize special features and markings that identify hybrid and electric vehicles.
Hybrid Electric Vehicle Myth or Reality? Special equipment is needed for hybrid and electric vehicle fires. 1-14 MYTH
Hybrid Electric Vehicle Special equipment is needed for hybrid and electric vehicle fires. 1-15 Typical fire fighting equipment can be used to extinguish fires in these vehicles, but you may need to adjust your tactics.
Hybrid Electric Vehicle Myth or Reality? Extrication from these vehicles will be greatly hampered by high voltage cabling. 1-16 MYTH
Hybrid Electric Vehicle Extrication from these vehicles will be greatly hampered by high voltage cabling. 1-17 ●High voltage cabling generally will NOT impede operations. ●Not usually placed in common cut points. ●Commonly runs under floor.
Hybrid Electric Vehicle Myth or Reality? Batteries will leak a significant amount of electrolyte if damaged or breached. 1-18 MYTH
Hybrid Electric Vehicle Batteries will leak a significant amount of electrolyte if damaged or breached. 1-19 ●Batteries are in protective cases. ●If case is breached, batteries will NOT leak a significant amount of electrolyte. ●NiMH and Li-Ion are dry cell batteries, and may produce a few drops per cell if crushed. Some models may leak coolant. This should not be confused with electrolyte.
Hybrid Electric Vehicle Myth or Reality? Electrocution is likely from touching a hybrid or electric vehicle involved in a crash or submerged in water. 1-20 MYTH
Hybrid Electric Vehicle Electrocution is likely from touching a hybrid or electric vehicle involved in a crash or submerged in water. 1-21 ●The high voltage systems are designed to prevent electrical hazards after a crash. ●High voltage systems are isolated from the vehicle chassis. ●They have integrated safety systems. Despite safety features, the potential hazards of the high voltage systems require use of correct procedures.
1-23 ●There are many myths about the risks posed by hybrid and electric vehicles. ●The reality is that there are numerous safety systems to protect responders. ●As always, the key to your safety is proper training. Myths versus Realities
HEV Hybrid Electric Vehicle A vehicle that has both an internal combustion engine (ICE) and electric motor(s). PHEV Plug-In Hybrid Electric Vehicle A vehicle that has both an ICE and electric motors, and can recharge its batteries to full charge from an external electric power source. EV Electric Vehicle A vehicle which uses only electric motor(s) for propulsion. 1-24 Definitions
History of EVs and HEVs First crude electric vehicles. 1832 to 1839 23% of all cars manufactured were electric. 1900 GM built a few thousand electric vehicles for lease. Program cancelled in 2003. 1997 to 2000 Tesla Roadster released.2006 1-25 Porsche builds first hybrid. 1889 Prototype hybrid Buick Skylark. 1974
Hybrid Electric Vehicle 1-26 2000 5000% Growth in HEV Sales in 9 Years 5,000Over 250,000 2009
Percentage of 2010 Hybrid Sales by Model Honda Insight Lexus RX450h Ford Fusion Toyota Camry Lexus HS 250h Toyota Highlander Honda Civic Ford Escape Toyota Prius Honda CRZ All others (20 models) 1-27
From this point on in the course, we will refer to all types of Hybrids and Plug-in Hybrids collectively as P/HEVs. In some instances, they may need to be referenced separately, in which case, they will be referred to as Hybrid (HEV) or Plug-In Hybrid (PHEV) respectively. 1-28 Terminology Electric Vehicles will be referred to as EVs.
