HYBRID VEHICLES HYBRID VEHICLES.ppt (Size: 551.5 KB / Downloads: 190) HYBRID STRUCTURE The 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 HYBRID Gasoline motor Batteries which powers an electric motor Both can power the transmission at the same time Electric motor supplements the gasoline engine SERIES HYBRID Gasoline motor turns a generator Generator may either charge the batteries or power an electric motor that drives the transmission At low speeds is powered only by the electric motor HIGH VOLTAGE ELECTRICAL SYSTEMS Power for the electric motor is supplied by high-voltage nickel-metal hydride battery Batteries for all hybrids are produced by Panasonic EV Energy in Japan Voltage ranges from 144 volts to 650 volts of DC current BATTERIES Individual cells originally contained liquid potassium hydroxide The liquid is almost totally absorbed by the paper membranes inside each cell of the battery Because the liquid is absorbed these batteries are considered “dry cell” batteries HIGH VOLTAGE ELECTRICAL SYSTEMS Batteries are usually located in the rear of the vehicle under the floor of the trunk or under the rear seat. The wiring harness from the batteries usually runs below the floorpan of the vehicle about one foot in from the driver’s side of the vehicle. BATTERY RECHARGING The Ni-MH batteries are recharged through a process call regenerative braking Regenerative 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 EMERGENCY PROCEDURESFIRES Vehicle fires can be handled following normal vehicle firefighting procedures Crews should not be shocked, even if flames are impinging on the battery pack itself Virtually all fires involving Ni-MH batteries can be controlled with water KEYLESS IGNITION SYSTEMS Convenience of push button start Systems are designed to deter theft and break-ins Utilize key fobs which contain a chip with an ID code that the vehicle must recognize The key fob must be in the vehicle in order for the car to start SUMMARY Due 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. |
