New energy vehicle super long warranty chaos

New energy vehicle super long warranty maintenance chaos

Under the influence of the recent policy of tax breaks, new energy vehicles set off a new round of “blowouts”. Beijing Traffic Control Department has announced that from June 1 this year, Beijing New Energy Vehicle will be opened "green light", not subject to tail number limit line. Stimulated by this news, many consumers began to consider purchasing a new energy vehicle. The data from the China Association of Automobile Manufacturers also shows that in the first four months of this year, China's new energy vehicle production was 34,400, an increase of nearly three times compared with the same period of last year, and it has surpassed the United States' 32,400, ranking first in the world.

When consumers purchase new energy vehicles, they value the ease with which they can obtain licenses, and their relatively low charging costs. Although new energy vehicles have a longer warranty period and lower maintenance costs than gasoline vehicles, there are still many problems to be solved in the area of ​​aftersales maintenance.

In a recent visit, Beijing Business Daily reporter found that when consumers purchase new energy vehicles, their warranty periods and maintenance costs are different. Taking Beijing as an example, the new energy vehicles currently sold on the market are Beiqi New Energy E150EV and EV200, BYD e6, JAC iEV4, Qichen Morrowind, and Tesla ModelS. Among them, the warranty period of Beiqi New Energy EV200 vehicle is three years or 60,000 kilometers, but the battery, motor and other core components provide six-year or 200,000 kilometers long warranty period. At the same time, Beiqi New Energy after-sales service personnel said that owners of BAIC New Energy EV200 are advised to visit the store every six months for maintenance. The maintenance cost is free for five years or 100,000 kilometers. In addition, 4S shop also provides free trailers and scooter services.

BYD e6 vehicle warranty period of up to six years or 150,000 kilometers, dealers presented four free maintenance, but does not provide the battery trade-in and scooter, consumers need trailers also have to pay the cost. The daily maintenance cost of Tesla ModelS requires the owner's own responsibility. A Tesla after-sales service staff said that Tesla ModelS's battery can be replaced directly during the warranty period, but the brake fluid of this model needs to be replaced within two years or 40,000 kilometers. The cost is 596 yuan; antifreeze In four years or 80,000 kilometers need to be replaced, the cost up to 1695 yuan; gearbox oil replacement in 12 years or 240,000 kilometers, the cost is 628 yuan.

Yan Jinghui, deputy general manager of the Asian Games Village Automotive Trading Market, said that although the cost of new energy vehicle maintenance is relatively low, but the current warranty period of new energy vehicles and after-sales car companies are each fighting, the entire vehicle warranty period, battery warranty period, whether the concept of maintenance fees , To make consumers feel puzzled, in the after-sales system and standards, car companies need to improve the standards.

In addition, as the batteries and charging piles installed by new energy vehicles are provided by a third party, if the vehicle owner fails during use, it may be necessary for car companies, battery providers, and charging pile installation companies to jointly resolve the problem. Compared with gasoline vehicles, Undoubtedly increased maintenance costs and time costs. Yan Jinghui believes that compared with the complete after-sales system for gasoline vehicles, new energy vehicles still belong to the emerging field, and the entire industry is still in the stage of “crossing the river by feeling stones”. As consumers begin to accept new energy vehicles, improving and refining the after-sales service system will become a shortcoming for all car companies to complete.

Non-woven special equipment accessories



Non-woven fabric is a new type of modern material. It has a wide range of uses and can play more roles in clothing, agriculture and industry. The production of non-woven fabrics is also mostly mechanized, which makes it possible to produce a large number of non-woven fabrics in batches. Non-woven fabric winders are one of its equipment.

Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. The production of non-woven fabrics often uses polypropylene pellets as raw materials, and is produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. In the production of non-woven fabrics, the raw materials need to be spun and formed and then processed. In the web-forming work, a non-woven web forming machine needs to be used. The web forming machine uses wind in the drafting duct to process the silk. After drafting, a machine for non-directional weaving into a net is carried out. However, polypropylene pellets are prone to broken filaments and stiff blocks during drawing, drafting, and web formation. Therefore, in order to improve the quality of the finished non-woven fabric, it is necessary to clean the formed non-woven fabric. When dealing with broken wires and stiff blocks in traditional web forming machines, workers usually use brushes or scouring pads behind the web forming machines to clean up. Because the belt width of the web forming machines is relatively long, and the conveyor belt speed is relatively high at the same time. Fast, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency, which in turn affects the quality of the finished non-woven fabric.

The slitting machine is mainly used to cut large-format non-woven fabrics into multiple small non-woven fabrics of different widths for processing non-woven products. The equipment adopts DC speed regulation, feeding constant tension control, air knife slitting, rewinding pressure and other devices. The rewinding tightness after slitting is adjustable, and the slitting end surface is flat. The equipment is of high quality and beautiful appearance. It is the ideal equipment for the slitting of large non-woven fabrics. In addition, according to the needs of users, the equipment can also add a dummy cutting function, that is, the original fabric is dummy cut and then slit and rewinded.

Non-woven fabric machinery is a general term for the production of non-woven fabric products, and adopts an overall modular design with a compact and reasonable structure. The control part adopts advanced PLC microcomputer control, and the international famous brand frequency converter speed regulation.
