How to see the electric car, is considered good?Such as the frequency of what ~ ~ please advise
The first is face.When you have identified a brand or a car, the first thing, of course, is the appearance. The process and level of painting directly affect the first sight of the car. Paint materials include primers, finishes and varnish. Different brands of paint directly affect the final results. Of course, when we choose the car, there is no way to know the specific paint brand used by the vehicle, but we can judge the quality of the paint according to the effect of paint baking. Good paint surface, transparent light, deep natural color, no uneven color, color and large pits or convex point block. Applique process is smooth, the paint is covered evenly. The sun, paint color bright color, shade, paint color and texture. These descriptions, if you find it difficult to understand, the easiest way is to go a few shops, the same color of the car, a lot of contrast, I feel very soon out. The most important point is to consider the paint anti UV ability, a lot of car paint do not add anti UV agents, the car after long-term exposure to the sun, will gradually fade, especially white paint, more susceptible to fading or discoloration problems. Because such problems can not be immediately judged, you can observe the car show whether there is a problem of color fading, make a basic assessment.
Followed by lining.The structure of the whole vehicle is very simple. The basic units are frame, plastic parts, shock absorbers, batteries, controllers and motors. The quality of the frame is particularly critical, and many users are less concerned with the quality of the frame because it is difficult to observe. However, the quality of the frame determines the safety performance of the vehicle directly. Here are some ways to validate the frame. First observe the level of welding of plastic parts inside the vehicle frame, if there is false welding, sealing off, the frame quality is not ideal. The second observation frame whether there is rust marks, because the frame in order to prevent rust need a called electrophoresis technology, many manufacturers in order to control the cost of the frame, simply spray black paint without electrophoresis, namely if the new rust problems, then the frame quality abnormal electrophoresis. Finally, the test run, high-speed travel, and then emergency braking, to see whether the car frame sway around, and if the shaking is very strong, indicating that the quality of the frame is not pass, there are security risks. Because the electric car market is mixed, the frame is hidden inside the vehicle, can not be checked directly, so many manufacturers are not strict control of the quality of the frame. Choosing the right frame is important to the vehicle. There is also a simple way, if the vehicle to remove the battery, you can hold up to try weight, the more heavy, indicating that the more solid vehicle materials, the greater the possibility of good safety performance.
