Let us learn more about the content of the wheel motors together.

Although electric cars made an unprecedented attention, but the battery is too heavy, trip mileage short problem has become its biggest soft rib, how can let electric cars run farther and don't increase battery weight? Expect at the time, the battery technology is impossible. In Los Angeles, porsche electric car-sensation that same year, a porsche came up with "gandour" measures: to electric cars loaded on a generator. And with regular petrol engine to drive generators, in this way, will not have to carry too much battery! This is the earliest series hybrid cars!To plug the merlin climbing based electric car, a Porsche launched in the autumn of 1900 the first prototype of the hybrid car, the name of it called Lohner-Porsche Semper Vivus. In the specific details, a porsche two sets of water will DeDion Bouton gasoline engine (3.5 each horsepower / 2.6 kw) into body middle, respectively for they drive two generator, constitute two sets of power units. Power 2.5 horsepower / 1.84 kw generator can be in 90 volts output voltage of the current 20 amperes, generator power output direct drive motor rotor hub outside, and the rest of the electrical energy flow into the battery is stored. And, in turn, can be used as the engine generator starter, kill two birds with one stone. Although, mount the engine-generator unit Semper Vivus use the battery packs of electric cars from the original 74 battery reduced to 44 piece, but because the engine and generator brought extra weight, make Semper Vivus weight still is the original electric version only 70 kg weight, but nearly 1.7 tons of weight for the pneumatic rubber tires at that time it is still a heavy burden-you can imagine carrying a bike with two sets a hippopotamus is what feeling...Anyway, Semper Vivus in the 1901 Paris auto show again let on "los on-Porsche (Lohner-Porsche)" this name to people left deep impression, however, in the more than the fresh, the car didn't like the world expo last year on that one of the electric car as moving heart, no body chassis, bare engine, etc. Let the prototype car looks can't make people poured out of the idea of buying. And at this time, whether engine, or the battery and the development of the control system are also but is "starving" phase, it should be said that the car cameras development of the technology is still far from surrounding couldn't keep up with the pace of innovation of porsche.The "the world the first" hybrid cars and not leave too much information, but porsche museum is in after more than one hundred years according to the current and pictures of the original technical drawings after carved a Semper Vivus.This is a difficult project, from Porsche engineering (Porsche engineering) engineers and Karosseriebau Drescher (a German car company) experts since 2007 spent nearly three years to finish this car DVD legend models rebirth. Engineer according to in those days the parameters and drawings made 100 years ago, the wheel motors, and body size and material also all follow the original, after carved Semper Vivus is not a scale model, but one can really driving up hybrids.
