The system for plugin hybrid vehicles (PHVs) has also been enhanced. A new dual motor drive system allows the electric motor, which was hitherto used only as a generator, to provide direct driving power, resulting in powerful driving, even when in EV mode. Further enhancing the system for PHVs is a large-capacity lithium-ion battery that largely increases the EV-mode cruising range to 60 kilometers or more*.
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system (hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors), buses, boats and aircraft also exist.
To take advantage of the emission reduction potential of hybrid electric vehicles (HEVs), appropriate design of their energy management systems (EMSs) to control the power flow between the engine and the battery is essential.
William H. Patton filed a patent application for a gasoline-electric hybrid rail-car propulsion system in early 1889, and for a similar hybrid boat propulsion system in mid 1889. He went on to test and market the Patton Motor Car, a gas-electric hybrid system used to drive tram cars and small locomotives. A gasoline engine drove a generator that served to charge a lead acid battery in parallel with the traction motors. A conventional series-parallel controller was used for the traction motors. A prototype was built in 1889, an experimental tram car was run in Pullman, Illinois, in 1891, and a production locomotive was sold to a street railway company in Cedar Falls, Iowa, in 1897.
During the Second World War, Ferdinand Porsche sought to use his firm's experience in hybrid drivetrain design for powering armored fighting vehicles for Nazi Germany. A series of designs, starting with the VK 3001 (P), the unsuccessful VK 4501 (P) heavy tank prototype (which became the Elefant tank destroyer) and concluding with the heaviest armored fighting vehicle ever prototyped, the Panzerkampfwagen Maus of nearly 190 tonnes in weight, were just two examples of a number of planned Wehrmacht "weapons systems" (including the highly-"electrified" subsystems on the Fw 191 bomber project), crippled in their development by the then-substandard supplies of electrical-grade copper, required for the electric final drives on Porsche's armored fighting vehicle powertrain designs.
In 1982, Fritz Karl Preikschat invented an electric propulsion and braking system for cars based on regenerative braking. While clearly not the only patent relating to the hybrid electric vehicle, the patent was important based on 120+ subsequent patents directly citing it. The patent was issued in the U.S. and the system was not prototyped or commercialized.
In 2006, General Motors Saturn Division began to market a mild parallel hybrid, the 2007 Saturn Vue Green Line, which utilized GM's Belted Alternator/Starter (BAS Hybrid) system combined with a 2.4-litre L4 engine and an FWD automatic transmission. The same hybrid powertrain was also used to power the 2008 Saturn Aura Greenline and Malibu Hybrid models. As of December 2009[update], only the BAS-equipped Malibu is still in (limited) production.
Global sales of the Toyota Prius liftback passed the 3 million milestone in June 2013. The Prius liftbak is available in almost 80 countries and regions, and it is the world's best-selling hybrid electric vehicle. Toyota released the hybrid versions of the Corolla Axio sedan and Corolla Fielder station wagon in Japan in August 2013. Both cars are equipped with a 1.5-liter hybrid system similar to the one used in the Prius c.
Diesel hybrid technology, introduced by PSA Peugeot Citroën with the HYbrid4 system in 2011, represented 20.2% of the hybrid car stock sold in France between 2011 and 2014. Among the 13,340 units registered in 2011, the top-selling models in the French market were the Toyota Auris (4,740 units), the Prius (2,429 units), and the Honda Jazz Hybrid (1,857 units). The diesel-powered Peugeot 3008 HYbrid4, launched in late 2011, sold 401 units. Toyota led hybrid sales in the French market in 2013 with 27,536 registrations of its Yaris, Auris and Prius models, followed by the PSA group with 13,400 registrations. During 2014, a total of 42,813 hybrid cars and vans were registered, down 8.5% from 2013. Of these, 9,518 were diesel-electric hybrids, down 31.9% from 13,986 units a year earlier, while registrations of gasoline-electric hybrids were up 1.5%. The top-selling models in 2014 were the Toyota Yaris Hybrid with 12,819 units, Toyota Auris with 10,595 and the Peugeot 3008 with 4,189 units. Hybrid registrations in 2014 included 1,519 plug-in hybrids, with sales led by the Mitsubishi Outlander P-HEV, with 820 units.
The most prominent example of a full hybrid diesel system is the HYbrid4 by PSA Peugeot-Citroën. It was discontinued in 2016, following the decline in diesel popularity following the VW Dieselgate scandal.Diesel-electric HEVs use a diesel engine for power generation. Diesels have advantages when delivering constant power for long periods of time, suffering less wear while operating at higher efficiency. The diesel engine's high torque, combined with hybrid technology, may offer substantially improved mileage. Most diesel vehicles can use 100% pure biofuels (biodiesel), so they can use but do not need petroleum at all for fuel (although mixes of biofuel and petroleum are more common). If diesel-electric HEVs were in use, this benefit would likely also apply. Diesel-electric hybrid drivetrains have begun to appear in commercial vehicles (particularly buses); as of 2007[update], no light duty diesel-electric hybrid passenger cars are available, although prototypes exist. Peugeot is expected to produce a diesel-electric hybrid version of its 308 in late 2008 for the European market.
Some vehicles like mostly cars and occasionally other vehicles combine the solar photovoltaic cell propulsion system with an electric battery that is charged by the solar panel or sometimes like plug-in hybrid vehicles can also be charged from the power grid. These types of vehicles are technically hybrids, although they consist of two types of cells, since both of them use different fuels. The advantage of combining the two systems is that the vehicle can function with the battery if there is no sunlight and also reduces the risk of getting stuck on the road in case of a battery depletion since the solar panels charge the battery simultaneously.
In some cases, manufacturers are producing HEVs that use the added energy provided by the hybrid systems to give vehicles a power boost, rather than significantly improved fuel efficiency compared to their traditional counterparts. The trade-off between added performance and improved fuel efficiency is partly controlled by the software within the hybrid system and partly the result of the engine, battery and motor size. In the future, manufacturers may provide HEV owners with the ability to partially control this balance (fuel efficiency vs. added performance) as they wish, through a user-controlled setting. Toyota announced in January, 2006 that it was considering a "high-efficiency" button.
Any combination of these three primary hybrid advantages may be used in different vehicles to realize different fuel usage, power, emissions, weight and cost profiles. The ICE in an HEV can be smaller, lighter, and more efficient than the one in a conventional vehicle, because the combustion engine can be sized for slightly above average power demand rather than peak power demand. The drive system in a vehicle is required to operate over a range of speed and power, but an ICE's highest efficiency is in a narrow range of operation, making conventional vehicles inefficient. On the contrary, in most HEV designs, the ICE operates closer to its range of highest efficiency more frequently. The power curve of electric motors is better suited to variable speeds and can provide substantially greater torque at low speeds compared with internal-combustion engines. The greater fuel economy of HEVs has implication for reduced petroleum consumption and vehicle air pollution emissions worldwide
As emissions regulations become tougher for manufacturers to adhere to, a new generation of high-performance cars will be powered by hybrid technology (for example the Porsche GT3 hybrid racing car). Aside from the emissions benefits of a hybrid system, the immediately available torque which is produced from electric motor(s) can lead to performance benefits by addressing the power curve weaknesses of a traditional combustion engine. Hybrid racecars have been very successful, as is shown by the Audi R18 and Porsche 919, which have won the 24 hours of Le Mans using hybrid technology.
Hybrid technology for buses has seen increased attention since recent battery developments decreased battery weight significantly. Drivetrains consist of conventional diesel engines and gas turbines. Some designs concentrate on using car engines, recent designs have focused on using conventional diesel engines already used in bus designs, to save on engineering and training costs. As of 2007[update], several manufacturers were working on new hybrid designs, or hybrid drivetrains that fit into existing chassis offerings without major re-design. A challenge to hybrid buses may still come from cheaper lightweight imports from the former Eastern bloc countries or China, where national operators are looking at fuel consumption issues surrounding the weight of the bus, which has increased with recent bus technology innovations such as glazing, air conditioning and electrical systems. A hybrid bus can also deliver fuel economy though through the hybrid drivetrain. Hybrid technology is also being promoted by environmentally concerned transit authorities. 041b061a72
