*WHAT IS A HYBRID VEHICLE?Any vehicle which combines two or more sources of power.
Examples:Diesel electricNuclear electricGasoline - electric
*HYBRID STRUCTUREThe two power sources found in hybrid vehicles may be combined in different ways, either in parallel or series
Either one will allow the gasoline engine to shut down when it is not needed.
*PARALLEL HYBRIDGasoline motorBatteries which powers an electric motorBoth can power the transmission at the same timeElectric motor supplements the gasoline engine
*SERIES HYBRIDGasoline motor turns a generatorGenerator may either charge the batteries or power an electric motor that drives the transmissionAt low speeds is powered only by the electric motor
*HIGH VOLTAGE ELECTRICAL SYSTEMSPower for the electric motor is supplied by high-voltage nickel-metal hydride batteryBatteries for all hybrids are produced by Panasonic EV Energy in JapanVoltage ranges from 144 volts to 650 volts of DC current
*HIGH VOLTAGE ELECTRICAL SYSTEMSHigh voltage wiring may color coded orange, bright blue or even yellow
Batteries vary in design, however, all incorporate individual cells connected to one another
*BATTERIESIndividual cells originally contained liquid potassium hydroxideThe liquid is almost totally absorbed by the paper membranes inside each cell of the batteryBecause the liquid is absorbed these batteries are considered dry cell batteries
*BATTERY RECHARGINGThe Ni-MH batteries are recharged through a process call regenerative brakingRegenerative braking takes energy from the forward momentum of the vehicle and captures it while coasting or braking.Occasionally batteries are recharged by the electric motor

*SUMMARYDue to the proliferation of hybrid vehicles on the road today, responders must be familiar with how these vehicles operate, and how to handle an emergency which involves one of these vehicles.Additionally, responders must stay up-to-date with current vehicle technology, as it is continuously changing.
