 * a hybrid vehicle** is a vehicle that uses two or more distinct power sources to move the vehicle.[|[][|1][|]] The term most commonly refers to [|hybrid electric vehicles] (HEVs), which combine an [|internal combustion engine] and one or more [|electric motors].

[[|edit]] Power
Power sources for hybrid vehicles include:
 * On-board or out-board [|rechargeable energy storage system] (RESS)
 * [|Compressed air]
 * [|Coal], wood or other solid combustibles
 * [|Electricity]
 * [|Electromagnetic fields], [|Radio waves]
 * [|Compressed] or [|liquefied natural gas]
 * [|Human powered] e.g. pedaling or rowing
 * [|Hydrogen]
 * [|Liquid nitrogen]
 * [|Petrol] or [|Diesel fuel]
 * [|Solar]
 * [|Wind]
 * [|Waste heat] from internal combustion engine.

[[|edit]] Two-wheeled and cycle-type vehicles
[|Mopeds], [|electric bicycles], and even [|electric kick scooters] are a simple form of a hybrid, as power is delivered both via an [|internal combustion engine] or [|electric motor] and the rider's muscles. Early prototypes of motorcycles in the late 19th century used the same principles. The first known prototype and publication of an SH bicycle is by Augustus Kinzel (US Patent 3'884'317) in 1975. In 1994 Bernie Macdonalds conceived the Electrilite[|[][|4][|]] SH lightweight vehicle which used power electronics allowing regenerative braking and pedaling while stationary. In 1995 Thomas Müller designed a "Fahrrad mit elektromagnetischem Antrieb" in his 1995 diploma thesis and built a functional vehicle. In 1996 Jürg Blatter and Andreas Fuchs of Berne University of Applied Sciences built an SH bicycle and in 1998 mounted the system onto a [|Leitra] tricycle (European patent EP 1165188). In 1999 Harald Kutzke described his concept of the "active bicycle": the aim is to approach the ideal bicycle weighing nothing and having no drag by electronic compensation. Until 2005 Fuchs and colleagues built several prototype SH [|tricycles] and [|quadricycles].[|[][|5][|]]
 * In a **parallel hybrid bicycle** human and motor power are mechanically coupled at the pedal drive train or at the rear or the front wheel, e.g. using a hub motor, a roller pressing onto a tire, or a connection to a wheel using a transmission element. Human and motor torques are added together. Almost all manufactured models are of this type. See [|Motorized bicycles], [|Mopeds] and[|[][|2][|]] for more information.
 * In a **series hybrid bicycle** (SH) the user powers a generator using the pedals. This is converted into electricity and can be fed directly to the motor giving a [|chainless bicycle] but also to charge a battery. The motor draws power from the battery and must be able to deliver the full mechanical torque required because none is available from the pedals. SH bicycles are commercially available, because they are very simple in theory and manufacturing.[|[][|3][|]]

[[|edit]] Heavy vehicles
Hybrid [|power trains] use [|diesel-electric] or [|turbo-electric] to power railway locomotives, buses, heavy goods vehicles, mobile [|hydraulic machinery], and ships. Typically some form of heat engine (usually diesel) drives an electric generator or hydraulic pump which powers one or more electric or hydraulic motors. There are advantages in distributing power through wires or pipes rather than mechanical elements especially when multiple drives—e.g. driven wheels or propellers—are required. There is power lost in the double conversion from typically diesel fuel to electricity to power an electric or hydraulic motor. With large vehicles the advantages often outweigh the disadvantages especially as the conversion losses typically decrease with size. With the exception of non nuclear [|submarines], presently there is no or relatively little secondary energy storage capacity on most heavy vehicles, e.g. auxiliary batteries and [|hydraulic accumulators]—this is changing.

Rail transport
Main article: [|Hybrid train] An is the new [|Autorail à grande capacité] (AGC or high-capacity railcar) built by the Canadian company [|Bombardier] for service in France. This has dual mode (diesel and electric motors) and dual voltage capabilities (1500 and 25000 V) allowing it to be used on many different rail systems.[|[][|6][|]] A The locomotive has been on trials in Rotterdam, the Netherlands with [|Railfeeding], a Genesse and Wyoming company. The First Hybrid [|Evaluating prototype] locomotive was designed and contracted by rail research center [|MATRAI] in 1999 and the sample was ready in 2000. it was a G12 locomotive that was converted to hybrid by using a 200KW diesel generator and batteries and also was equipped with 4 AC traction motors (out of 4) retrofited in the cover of the DC traction motors. The first operational prototype of a hybrid train engine with significant energy storage and energy regeneration capability was introduced in Japan as the [|KiHa E200]. It utilizes battery packs of [|lithium ion batteries] mounted on the roof to store recovered energy.[|[][|7][|]] In the U.S., [|General Electric] introduced a prototype railroad engine with their "Ecomagination" technology in 2007. They store energy in a large set of [|sodium nickel chloride] (Na-NiCl2) batteries to capture and store energy normally dissipated during [|dynamic braking] or coasting downhill. They expect at least a 10% reduction in fuel use with this system and are now spending about $2 billion/yr on hybrid research.[|[][|8][|]] Variants of the typical [|diesel electric locomotive] include the [|Green Goat] (GG) and [|Green Kid] (GK) [|switching/yard engines] built by Canada's [|Railpower Technologies]. They utilize a large set of heavy duty long life (~10 yr) rechargeable [|lead acid] (Pba) batteries and 1000 to 2000 HP electric motors as the primary motive sources and a new clean burning diesel generator (~160 Hp) for recharging the batteries that is used only as needed. No power or fuel are wasted for idling—typically 60–85% of the time for these type locomotives. It is unclear if [|dynamic braking] (regenerative) power is recaptured for reuse; but in principle it should be easily utilized. Since these engines typical need extra weight for traction purposes anyway the battery pack's weight is a negligible penalty. In addition the diesel generator and battery package are normally built on an existing "retired" "yard" locomotive's frame for significant additional cost savings. The existing motors and running gear are all rebuilt and reused. Diesel fuel savings of 40–60% and up to 80% pollution reductions are claimed over that of a "typical" older switching/yard engine. The same advantages that existing hybrid cars have for use with frequent starts and stops and idle periods apply to typical switching yard use.[|[][|9][|]] "Green Goat" locomotives have been purchased by [|Canadian Pacific Railway], [|BNSF Railway], [|Kansas City Southern Railway] and [|Union Pacific Railroad] among others.

[[|edit]] Cranes
Railpower Technologies Corp. engineers working with [|TSI Terminal Systems Inc.] in Vancouver, British Columbia are testing a hybrid diesel electric power unit with battery storage for use in [|Rubber Tyred Gantry] (RTG) cranes. RTG cranes are typically used for loading and unloading shipping containers onto trains or trucks in ports and container storage yards. The energy used to lift the containers can be partially regained when they are lowered. Diesel fuel and emission reductions of 50–70% are predicted by Railpower engineers.[|[][|10][|]] First systems are expected to be operational in 2007.[|[][|11][|]]

Road transport, commercial vehicles


GM has launched hybrid versions of its full-size [|GMC Yukon] (//pictured//) and [|Chevrolet Tahoe] SUVs for 2008

Early hybrid systems are being investigated for trucks and other heavy highway vehicles with some operational trucks and buses starting to come into use. The main obstacles seem to be smaller fleet sizes and the extra costs of a hybrid system are yet compensated for by fuel savings,[|[][|12][|]] but with the price of oil set to continue on its upward trend, the tipping point may be reached by the end of 1995. [//[|dated info]//] Advances in technology and lowered battery cost and higher capacity etc. developed in the hybrid car industry are already filtering into truck use as Toyota, Ford, GM and others introduce hybrid pickups and SUVs. Kenworth Truck Company recently introduced a hybrid-electric truck, called the Kenworth T270 Class 6 that for city usage seems to be competitive.[|[][|13][|]][|[][|14][|]] [|FedEx] and others are starting to invest in hybrid delivery type vehicles—particularly for city use where hybrid technology may pay off first.[|[][|15][|]]

Military off-road vehicles
Since 1985, the U.S. military has been testing [|serial hybrid] [|Humvees][|[][|16][|]][|[][|17][|]] and have found them to deliver faster acceleration, a [|stealth] mode with low [|thermal signature]/ near silent operation, and greater fuel economy.

[[|edit]] Ships
Ships with both mast-mounted [|sails] and [|steam engines] were an early form of hybrid vehicle. Another example is the [|diesel-electric] [|submarine]. This runs on batteries when submerged and the batteries can be re-charged by the [|diesel engine] when the craft is on the surface. Newer hybrid ship-propulsion schemes include large [|towing kites] manufactured by companies such as [|SkySails]. Towing kites can fly at heights several times higher than the tallest ship masts, capturing stronger and steadier winds.

[[|edit]] Aircraft
Taxiing and other ground operations of Boeing 737NGs will soon be done using hybrid electric drives as [|WheelTug] ground propulsion systems become available.[|[][|18][|]][|[][|19][|]] By using the [|APU] (powered by a turbine) to energize a [|Chorus electric motor] mounted in the landing gear for ground movement, aircraft will be operating in a hybrid configuration where the main engines are used only for take off, landing, and flight. [|Boeing 737-800] The Boeing Fuel Cell Demonstrator Airplane has a Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor, which is coupled to a conventional propeller. The fuel cell provides all power for the cruise phase of flight. During takeoff and climb, the flight segment that requires the most power, the system draws on lightweight lithium-ion batteries. The demonstrator aircraft is a Dimona motor glider, built by Diamond Aircraft Industries of Austria, which also carried out structural modifications to the aircraft. With a wing span of 16.3 meters (53.5 feet), the airplane will be able to cruise at approximately 100 kilometers per hour (62 miles per hour) on power from the fuel cell.[|[][|20][|]]

[[|edit]] Hybrid electric-petroleum vehicles


Hybrid [|New Flyer] [|Metrobus]



Hybrid [|Optare Solo]

Main article: [|Hybrid electric vehicle] When the term //hybrid vehicle// is used, it most often refers to a [|Hybrid electric vehicle]. These encompass such vehicles as the [|AHS2] ([|Chevrolet Tahoe], [|GMC Yukon], [|Chevrolet Silverado], [|Cadillac Escalade], and the [|Saturn Vue]), [|Toyota Prius], [|Toyota Camry Hybrid], [|Ford Escape Hybrid], [|Toyota Highlander Hybrid], [|Honda Insight], [|Honda Civic Hybrid] Lexus RX 400h and 450h and others. A petroleum-electric hybrid most commonly uses [|internal combustion] engines (generally gasoline or [|Diesel engines], powered by a variety of fuels) and [|electric batteries] to power the vehicle. There are many [|types of petroleum-electric hybrid drivetrains], from **Full hybrid** to [|Mild hybrid], which offer varying advantages and disadvantages.[|[][|21][|]] [|Ferdinand Porsche] in 1900 developed the first gasoline-electric [|series-hybrid] automobile in the world, setting speed records using two [|motor-in-wheel-hub arrangements] with a combustion generator set providing the electric power. While liquid fuel/electric hybrids date back to the late 19th century, the braking regenerative hybrid was invented by David Arthurs, an electrical engineer from Springdale, Arkansas in 1978–79. His home-converted Opel GT was reported to return as much as 75MPG with plans still sold to this original design, and the "Mother Earth News" modified version on their website.[|[][|22][|]] The plug-in-electric-vehicle (PEV) is becoming more and more common. It has the range needed in locations where there are wide gaps with no services. The batteries can be plugged in to house (mains) electricity for charging, as well being charged while the engine is running.

[[|edit]] Continuously outboard recharged electric vehicle (COREV)
Given suitable infrastructure, permissions and vehicles, [|BEVs] can be recharged while the user drives. The BEV establishes contact with an electrified rail, plate or overhead wires on the highway via an attached conducting wheel or other similar mechanism (see [|Conduit current collection]). The BEV's batteries are recharged by this process—on the highway—and can then be used normally on other roads until the battery is discharged. This provides the advantage, in principle, of virtually unrestricted highway range as long as you stay where you have BEV infrastructure access. Since many destinations are within 100 km of a major highway, this may reduce the need for expensive battery systems. Unfortunately private use of the existing electrical system is nearly universally prohibited. The technology for such electrical infrastructure is old and, outside of some cities, is not widely distributed (see [|Conduit current collection], [|trams], [|electric rail], [|trolleys], [|third rail]). Updating the required electrical and infrastructure costs can be funded, in principle, by toll revenue, gasoline or other taxes.
