Since the Chinese government decided to develop new energy vehicles, technologies and the entire industrial chain in 2014, many local car manufacturers have joined forces. In 2014, more than 74,000 new energy vehicles were sold in the Chinese market; in 2015, 330,000 new energy vehicles were sold in the Chinese market; in 2016 (as of June), more than 170,000 new energy vehicles were sold in the Chinese market. 300,000 units were sold. Nearly 90% of the total sales of new energy vehicles worldwide are from the Chinese market. It is not optimistic to estimate that the total sales of new energy vehicles in the Chinese market will exceed 5 million units by 2025. In China's new energy market, many car manufacturers, including joint venture brands, are gearing up to seize the market and gain market share in new cars and new technologies. However, in the after-sales service market of new energy vehicles, many automakers have been “intentionally or unintentionally†left out. Later in 2015, the author wrote that “in 2016, China's new energy market will move from pre-sales to after-salesâ€. From 2014 to 2016, nearly 650,000 new energy vehicle stocks have been generated and distributed in a few cities such as North, Shanghai, Guangzhou and Shenzhen. This means that the after-sales service of these private homes, official services, public transport and rental new energy vehicles will be handled by no more than 100 4S shops or service stations set up by each car manufacturer. 550,000 new energy vehicles, compared to 50 (average) of each (local brand) 4S shop in a single day, the pressure is big! This kind of pressure is not only the shortage of 4S shops (service stations), but also the shortage of full-time technicians with deep maintenance and maintenance of new energy vehicles. In the past 3 years, the author has encountered many new energy brand electric vehicles in the test drive, not starting, not charging, not "extinguish" (power off), no driving and other serious faults, as well as abnormal noise, steering abnormal noise , serious mileage calculation error, air conditioning system failure and other serious faults. Whenever these problems occur, they must be solved with 4S shops and service stations. Then the problem came, the 4S shop in the early stage of the development of the new energy market, and did not separate the full-time department from the brand. These experienced storefronts or technicians who maintain the traditional car, despite having the relevant training qualifications, still have difficulty in solving the problem for the owner in a short time in the event of a more complicated new energy vehicle failure. The author received in the past 2015, 2016 (before July), feedback from the JAC iEV5 owners, charging faults, Geely Dorsett EV owners feedback electronic parking system failure, BYD e6 owners feedback brake light switch faults, etc. Simple question. These service problems originating from the OEMs have already begun to affect the sales performance of the OEMs. In fact, by the end of 2015, China's new energy market will still focus on the pre-sales market, and the after-sales market will be improved from June 2016. Earlier in October 2016, the 2016 National Machinery Industry Vocational College Competition “BAIC New Energy Cup†pure electric vehicle service skill competition was carried out through the joint efforts of vehicle manufacturers and institutions to cultivate talents at the source. To provide protection for the new energy vehicle aftermarket. At the awarding ceremony, the deputy general manager of Beiqi New Energy Service, Yang Jiaxuan, announced that the winners of the competition can unconditionally enter the new energy service system of BAIC. After the game, Vice President Yang Jiaxuan revealed to the author that BAIC New Energy has “scheduled†this group of professional technicians from the whole country who have been specially trained to repair new energy vehicles (BAIC New Energy Brand). These trainees already have training experience in traditional automobile theory and practical training, and new energy service talents who will receive further in-depth training will be distributed to the national Beiqi new energy service system. In the pure electric vehicle service skill competition, the students assessed the faults of the motor, power battery, brake system, electronic control system, charging system and air conditioning system of Beiqi New Energy EV160 series electric vehicles, and focused on training and design. Process and precautions in piezoelectric and control systems. Because of the difference between new energy vehicles and traditional vehicles, there are strict requirements for 4S shops and service stations in the construction of maintenance sites and training of maintenance technicians. This requires the manufacturer to closely cooperate with the training organization to disclose the production and maintenance information of its products. This kind of in-depth cooperation is also an area that many other brand car manufacturers are reluctant to get involved with on the grounds of confidentiality. This brings problems such as opaque and asymmetrical information to the training of service personnel. Technicians who repair new energy vehicles must strictly abide by the personal protection rules and procedures, and they can only have qualifications for training after strict training. So far, among the many brands of 4S shops and service stations, only a handful of technologies have the skills to replace the power battery and debug the vehicle control system for new energy vehicles. With the increase in sales of new energy vehicles, the frequency of repairs requiring replacement of power batteries has increased significantly due to problems such as collisions and human operations. The cultivation of talents is imperative. The author has something to say: The author who has worked in the frontline of 4S shop for 7 years is very clear that the cooperation between BAIC and New Energy has fostered the importance of specialized maintenance personnel at the source. This behavior is also the second time that Beiqi New Energy is in the forefront of the industry. The author never denies that the new energy vehicles developed and manufactured by BAIC New Energy have such problems as the goods, but these problems from design, manufacturing and service are in Jianghuai, Geely, SAIC, BYD, Toyota, Tesla, etc. The same exists in the brand. However, joint ventures or imported brands such as Toyota and Tesla are not being criticized for their huge advantages in service. In order to meet the emergency rescue needs of 4S shops and service stations, Beiqi New Energy allotment standard rescue vehicles modified by Prestige 307EV. The vehicle is equipped with a generator, a fast and slow charging system, maintenance tools and safety protection. In traditional cars, Chinese brands are developing rapidly, but the progress in service development is still short-circuited by the joint venture brand. The Chinese government's full support for the new energy industry requires a healthy and comprehensive and balanced development of many local brands in vehicle design, manufacturing, sales and after-sales service. In extension, China's new energy industry is developing at full speed, not only involving automakers and technical training institutions, but also charging facilities suppliers into the system. In fact, today's China's new energy vehicle aftermarket is in urgent need of rectification and regulation.
Slide Switches
The Slide Switches is used to switch the circuit by turning the switch handle to turn the circuit on or off. It is different from our other serious switches, for example, Metal Switches, Automotive Switches, LED light Switches, Push Button Switches, Micro Switches, The commonly used varieties of Miniature Slide Switches are single pole double position, single pole three position, double pole double position and bipolar three position. It is generally used for low voltage circuits, featuring flexible slider action, stable and reliable performance. Mainly used in a wide range of instruments, fax machines, audio equipment, medical equipment, beauty equipment, and other electronic products.
