life problems of pure electric vehicles has been hindering some people choose to buy it it’s a great cause, especially in a fading environment temperature is too low mileage and high-speed cruising, but also so many consumers “at arm’s length.” Today we will discuss this issue with high-speed cruise of pure electric vehicles, high-speed cruise to talk about why the pure electric car, it can be disadvantageous.
fixed gear ratio transmission
different from the electric vehicle fuel vehicle, fundamental sense, pure electric vehicles no gearbox, whether in any of the speed ranges are fixed gear ratio transmission. That is why, pure electric vehicles when considering the gear ratio is set, will try to take into account more speed segment, resulting in a lower part of the speed-power performance segment is not ideal. When the most simple example, gear ratio setting more conducive to urban driving, surely not conducive to high-speed driving, here is more of a question of choice, it is difficult to solve.
Why do not install the gearbox?
Since pure electric car is not suitable for high-speed cruise of reason would be the gearbox, so why not give car manufacturers electric car assembly gearbox it? The reason is very simple: weight. Innate characteristics is limited to pure electric vehicles, the quality itself will be relatively large, if the weight at this time then the gearbox into account, not only will turn constraints mileage, but also has arranged a series of problems such as. Based on the above said, it is now the vast majority of electric vehicles as a fixed gear ratio transmission.
Summary: The above is some of the problems of pure electric vehicles, high-speed cruise of answers. Do not understand or have any comments can give us a message in the comments section, we see the next article.
