Hybrid Electric Vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle which combines a conventional internal combustion engine (ICE) propulsionsystem with an electric propulsion system. The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There are a variety of HEV types, and the degree to which they function as EVs varies as well. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors) and buses also exist.
Modern HEVs make use of efficiency-improving technologies such as regenerative braking, which converts the vehicle's kinetic energy into electric energy to charge the battery, rather than wasting it as heat energy as conventional brakes do. Some varieties of HEVs use their internal combustion engine to generate electricity by spinning an electrical generator (this combination is known as a motor-generator), to either recharge their batteries or to directly power the electric drive motors. Many HEVs reduce idle emissions by shutting down the ICE at idle and restarting it when needed; this is known as a start-stop system. A hybrid-electric produces less emissions from its ICE than a comparably sized gasoline car, since an HEV's gasoline engine is usually smaller than a comparably sized pure gasoline-burning vehicle (natural gas and propane fuels produce lower emissions) and if not used to directly drive the car, can be geared to run at maximum efficiency, further improving fuel economy.
New hybrid system combines the SDV6 diesel from the Range Rover Sport with a 46bhp electric motor to produce a combined output of 335bhp and 516lb f...t of torque. Both figures are identical to the output of the current SDV8 diesel engine available in the Range Rover.
The hybrid system’s key selling point is its impressive fuel economy and emissions figures. Land Rover says both the Range Rover and Range Rover Sport Hybrid models achieve 44.1mpg in official tests, and emit 169g/km of CO2.
3-cylinder, rear, 1.5 liters and an electric motor under the hood, a device for the front axle. Both power units can operate independently of one another.
Small but efficient 3-cylinder engine x 220 hp in connection with the electric... motor gives performance sports car with fuel compacts. BMW I8 acceleration to 100 km / h in less than 5 seconds and fuel consumption of only 2.7 liters per 100 kilometers.
Without recharging the battery can travel 35 kilometers, so in the main urban trips will be to not use gasoline engine and electric motor to move alone. The battery is located under the floor in the center console, and thus the car has a low center of gravity, giving excellent stability.
And of course electricity can also power vehicles via pure electric or hybrid technology. Find out more about plug-in vehicles, of look for used hybrid cars for sale.
The engine in these vehicles is always assisted by an electric motor (for example, the Honda Insight). The engine stops when the car is at rest and re-starts as soon as the accelerator is pressed to move off. This allows a smaller petrol engine to be used and improves fuel economy, particularly in urban and suburban driving. The battery is charged by the engine when the car is not accelerating, and energy from braking is also used to recharge the battery in a process called regenerative braking.

A123 And MIT Startup Working On 4X Energy Density Batteries
Yesterday, “technology in
cubator” A123 Venture Technologies announced it would collaborate with SolidEnergy, an MIT startup, on advanced batteries with up to four times lithium-ion energy densities. A123 Venture Technologies is a business arm of the revived A123 Systems LLC now owned by the Wanxiang Group and the investment in SolidEnergy’s “transformative solid electrolyte technology” is […]
