Powerful motor, wide-range and does not emit CO2, BMW promises C-Evolution will be the large-size model electric scooter developed for large-sized scooter trend
Most everyone knows the BMW as a manufacturer of cars, but few people know that the White-Green logo of the Bavarian has already mounted on the motorcycle for several decades. Branching out to produce their vehicles as the BMW Motorrad,
It is responsible for developing the means of moving the personal as well as a solution in the near future.
To meet this two large scooter products C600 Sport and C650 GT as a production was launched in 2011. However, rising fuel costs and increasing CO2 emissions standards more stringent than for the move out of the city in Europe has made these scooter use their combustion engine seems to like having no small challenge. The challenge has led to the birth of the electric motorcycle BMW C-Evolution.
Although the model C-Evolution is still in its final test before the official was at the Paris Motor Show 2012 but this will allow BMW Motorrad has more experience in the field of high-performance electric motorcycles, as well as the necessary preparation for the introduction of a series of computer models in the not so distant future. Two very specific requirements are given when BMW Motorrad developed the model C-Evolution is the comparative figures that make up the difference with a large scooter using the combustion engine and the ability to use in practical terms in a long time.
BMW C-Evolution was developed based on the chassis of the C600 Sport but that doesn't mean it's just add extra battery into this car. It would have been far more technical features very interesting that when sitting on C-Evolution will recognize the familiar to a conventional scooter. Sharp TFT display screen like the iPhone which lets you know the amount of batteries has been how much attrition during use.
The fuel cell cluster 8 kWh is similar to what BMW model for i3, contending the 1% battery going for 1 km, the maximum speed limit of 120 km/h electric operating range 100 miles will be reduced to about 64 km. BMW said the quality and longevity of the fuel cell cluster allows extending to 10 years and ensure operating range counting on staying well after many years of use as well as in cold weather conditions in Europe.
Interesting point on C-Evolution is the battery casing is made of cast aluminum monolithic, not only covered the pin but also acts as a part of the bearing frame. Battery weight is quite heavy, up to 80 kg. It is very low in the chassis and a low center of gravity is considered an important key point of C-Evolution.
One of the challenges is how to optimize the cooling capabilities of the fuel cell cluster. On the one hand, if the temperature is too low to make the resistance of the battery rises many rises leading to reduced engine power. On the other hand, the temperature is not too high as this could affect the lifespan of the batteries.
And finally, is cooled by air were BMW of choice for C-Evolution in order to save space and weight. The heat from the fuel cell was snubbed by an aerodynamic paths arranged at the center of the pin. In order to ensure optimum heat dissipation, power blocks were arranged in vertical frame. The batteries are recharged through the integrated charging device, common household outlet or in an electrical charge. BMW C-Evolution takes 3 hours to fully charge but just 45 minutes to charge the 70%.
BMW claims the power of C-Evolution will with the scooters used in conflict. With a maximum capacity of 35 kW, BMW C-Evolution possesses powerful engines and provides quick acceleration is the same as the controls on the market. Not only that, the car has a ability to handle flexibility in terms of ramps even at full passenger loads.
Compared to internal combustion engines, electric motors, C-Evolution also has significant advantages at low speed as faster scooters response and torque with no latency as in traditional combustion engines. The brake system of the C-Evolution technology recovers kinetic energy to charge the battery to increase operating range up to 10-20% when using this feature.
BMW C-Evolution looks slight sense although its weight up to 265 pounds, weighed more than 4 kg in comparison with the C650 gt. the car pretty hard by major chassis made from shells pin-are cast aluminum monolithic but giving C-Evolution capable of handling well. In addition, in order to reduce the friction roller makes the most efficient use of energy, C-Evolution is equipped with a light weight tires Metzeler Feelgreen which measures 120/70 R15 for the front wheels and 160/60 R15 for the rear wheel.
The only downside of the BMW C-Evolution is the vehicle noise and this can sometimes affect the means of moving around and through
