Английская Википедия:Brammo Enertia
Шаблон:Infobox Motorcycle The Enertia is an electric motorcycle designed and sold by Brammo, Inc. It uses a Lithium iron phosphate battery, and is intended as a commuter vehicle. Enertia motorcycles first went on sale in late July 2009,[1] and began selling at Best Buy in August 2009.[2]
Construction and components
The body uses monocoque construction. Early prototypes used carbon fiber as the principal material, but Brammo later decided to produce the monocoque body out of aluminum. Some of the bike's components are made entirely of recycled material, while the body panels are created from a mixed percentage of recycled and new materials.[3]
The Enertia's permanent magnet AC synchronous motor is powered by six Valence lithium iron phosphate battery modules, which can provide a top speed of over Шаблон:Convert.[3] The vehicle's batteries can be recharged via the onboard charger within three hours by plugging into a standard 110 volt electrical outlet.[4]
Brammo has stated the Enertia does not have regenerative braking because of the limited benefit that current regenerative braking technology provides to motorcycles, and the risk of traction problems.Шаблон:Citation needed
According to Cycle World magazine, "With its wide, mild-rise handlebar, sporty steering geometry and narrow 18-inch-front/17-inch-rear Avon RoadRiders, the Enertia is a light and responsive handler." The road test editor recorded a 0-60 mph time of 16.1 seconds, and a quarter-mile run of 20.19 seconds at 60.78 mph.[5]
The current testing versions of the Enertia being shown to the media are described as enjoyable to ride, nimble and easy to control. It is also capable of better speed than widely promised, up to Шаблон:Convert, although this quickly drains the battery.
Most of the cost of the motorcycle is due to the battery. Brammo is hoping for the cost of this component to fall in the future, and is talking of creating a program to lease rather than own the battery.[6]
Comparison with conventional motorcycles
With Шаблон:Convert, and Шаблон:Convert of torque in the 'performance' mode, the Enertia's power output is comparable to a conventionally powered Kawasaki Ninja 250 motorcycle.[7][8] However, the 2009 Ninja 250 has a top speed of Шаблон:Convert,[9] while the Enertia's top speed is 50 mph[7] or Шаблон:Convert.[3][10] It has no gears or clutch so shifting is not required, which Brammo claims enables the Enertia to go from Шаблон:Convert in 3.8 seconds in performance mode.[7] Tested by Cycle World, the Ninja 250 accelerates from Шаблон:Convert in 2.0 seconds.[11] Motorcycle Consumer News projected a range of Шаблон:Convert for the Ninja 250 based on their tested Шаблон:Convert.[9] Brammo claims the Enertia has a range of Шаблон:Convert between charges if power is set to the minimum level, 40%.[7]
At Шаблон:Convert[12][13] of carbon dioxide (CO2) per gallon consumed,[14] the Ninja 250 would emit Шаблон:Convert per Шаблон:Convert tank, or about Шаблон:Convert of Шаблон:Chem per year if ridden the US average of Шаблон:Convert per year.[15] The Enertia would consume 260 charges over the course of Шаблон:Convert at Шаблон:Convert per charge. With a battery pack capacity of 3.1 kW·h,[16] the annual consumption of electricity would be 806 kW·h. With a US national average emissions of Шаблон:Convert Шаблон:Chem per kW·h, the Enertia's yearly carbon emissions would be Шаблон:Convert.[15]
