motor manufacturers

Followed by the lining. The vehicle's structure is very simple, basic unit is the frame, plastic parts, shock absorption, batteries, controller, motor. The quality of the frame is particularly critical, 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 frame offers several verification methods for everyone. First observation of plastic parts inside the vehicle frame welding level, if there is a false welding, sealing off the case,motorcycle chassis manufacturer indicating that the quality of the frame is not ideal. Second, observe whether the frame has rusted signs, because the frame in order to prevent rusting need a process called electrophoresis, many frame manufacturers to control costs, but not simply sprayed black paint electrophoresis, if that is rusty car The problem, it shows the quality of the frame electrophoresis abnormal. The last test, at high speed and then the emergency brake, to see whether there is sloshing around the frame, if the shaking is very powerful, indicating the frame quality, but off, there are security risks. Because the electric car market was mixed, the frame is hidden inside the vehicle can not direct examination, so many manufacturers to control the quality of the frame is not critical. Pick to 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 with a more solid material, the greater the likelihood of better safety performance.

EV purchase method

The first is the face. When you identify a brand or a certain car models, the first thing, of course, is the appearance problem. electric disabled tricycle Technology and the level of paint, a direct impact on the feeling of the car at first glance. Paint materials containing primer, paint and varnish. Different brands of paint directly affect the final results. Of course we have no way of knowing the specific use of the vehicle paint brand car in the election, but we can judge the quality of the paint according to paint effect. Good paint, the surface of transparent light, natural color and deep, there should be no uneven color, color as well as a large area of ​​pits or bumps blocks. Applique craft flat, uniform paint coverage. Sun, bright colors paint color, shade, paint color, rich texture. These descriptions If you find it hard to understand, the easiest way is to take a few shops, a lot of the same color of car models contrast, feeling out soon. And most important thing is to consider baking UV resistance, many vehicles are not added UV paint formulations, the car after a long sun, will gradually fade, especially white paint, fading or discoloration of more problems. Because such issues can not judge now, we can observe the existence of a company's show car fade problem, make a basic assessment.

Knowledge and understanding of electric

1, correctly grasp the battery charging time to recharge a battery discharge depth of the best 60% -70%.
2, loss of electrical power loss state non-store that are not timely charging battery. Loss of power in the state of storage battery, it is prone to sulfate, lead sulfate crystals attached to the plates, plug the electric ion channels, resulting in insufficient charging, the battery capacity decreases. Idle state power loss longer, more severe damage to the battery. Therefore, the battery is left unused, should add power once a month, so that the battery can better maintain a healthy state.
3, avoid large current discharge electric car start, manned, uphill, please use the pedal assist to avoid momentary high-current discharge. Large current discharge easily lead to lead sulfate crystals to the detriment of the physical properties of the battery plates.
4, to prevent exposure to high temperature conditions may cause the battery to increase the internal pressure of the battery pressure limiting valve forced open automatically increase water loss is a direct consequence of the battery, and the battery will inevitably cause the battery to excessive water loss decreased activity, accelerate the plate to soften When charging the housing fever, from the drum housing, deformation and other fatal injuries.
