By 2020, new energy vehicles to achieve industrialization, energy-saving and new energy vehicles and key parts technology has reached the international advanced level, pure electric vehicles and plug-in hybrid vehicle market population reached 5 million. Analysis and forecasting, from 2012 to 2015 factory direct electric tricycle, electric car sales in the Chinese market, the average annual growth rate will reach 40%, most of which comes from a pure electric car sales by 2015, China will become Asia's largest electric car market. Tips to buy electric cars vehicle structure is very simple, basic unit is the frame, plastic parts, shock absorption, batteries, controllers, motors. The quality of the frame is particularly critical electric tricycle cargo, many users do not care about the quality of the frame, because this part is difficult to observe. But the quality of the frame directly determines the safety performance of the vehicle, the following provides several ways for you to verify the frame. First observation of plastic parts inside the vehicle frame welding level, if there is a false welding, sealing off the case, indicating that the quality of the frame is not ideal. Second, observe whether the frame rust marks, because the frame in order to prevent rusting process called electrophoresis requires a lot of frame manufacturers in order to control costs, just a simple black spray without electrophoresis electric tricycle, that is if a new car rust problem, it shows the quality of the frame electrophoresis abnormal. The last test, high speed and then the emergency brake, to see whether there is sloshing around the frame, if the rock is very powerful, indicating frame quality tests, there are security risks. Because the electric car market was mixed, the frame is hidden in the interior of the vehicle can not be directly checked, so many manufacturers to control the quality of the frame is not critical. To pick a good frame of the vehicle is very important. There is also a simple way to remove the battery if the vehicle, you can try to hold up the weight, the heavier the description of the vehicle the more solid material, the greater the likelihood of better safety performance.
