Is there a future for wireless charging, bidirectional conversion and high-power charging

whether the project is approved or not has a standard process. After evaluating according to the standard process, it is generally clear whether the project is approved or not. As many entrepreneurs with R & D backgrounds, Philip is the one who should make up a good lesson. In Kotler's marketing management, there is a SWOT analysis tool about the external environment, internal environment and competitor analysis of enterprises, which is not discussed by the old generation. In short, to start a project, we need to understand the smile curve. As shown in the following figure:

a smiling mouth curve, with both ends facing upward. In the industrial chain, the added value is more reflected at both ends, design and sales, and the manufacturing added value in the middle link is the lowest. In the middle of the smile curve is manufacturing; On the left is R & D, which belongs to global competition; On the right is marketing, mainly local competition. At present, the profits generated by manufacturing are low, and the global manufacturing has also been oversupplied, but the added value of R & D and marketing is high. Therefore, the industry should develop towards both ends of the smile curve in the future, that is, strengthen research and Exhibition on the left to create intellectual property rights, and strengthen customer-oriented marketing and services on the right

compared with wired charging, wireless charging is still a niche market, and there are many application directions of wireless charging, such as, electric vehicles, household appliances and underwater electrical equipment. The first step for start-ups is not what wireless charging technology I need, but what kind of customers can I find by looking at the right end of the smile curve? Then according to the reliable customers in the market, targeted development products. With the people who sell orders for their core technologies, the company has sustained cash flow, and the subsequent investment and reproduction will be expanded

the old generation once encountered a situation in which R & D personnel complained that the company's sales were not good and the products they developed could not be sold; After investigation, the old generation found that sales were also complaining that the product development required by customers was not coordinated, and the R & D personnel who could not sell in the market were actively developing. In this endless debate, it is actually a debate about whether a company is technology centric or customer-centric. Everyone is learning from Huawei, as boss Ren once said: whoever calls for artillery, of course, is to let the person who hears the artillery call for artillery

so is there a future for wireless charging, and can your own entrepreneurial project succeed? What matters is not the technology you own, but whether you find someone who is willing to sell you this technology

2. Is there a future for Bidirectional Transformation of charging piles

the market for charging piles is now very bad, and many start-ups are unwilling to get involved in this muddy water. But the V2G market has not risen, is it a good time to import

of course, most of the reasons for those who have this idea are that the bidirectional transformation technology has recently matured and has become a popular product in a few years, resulting in the idea that the entrance is also low. There are two ways to realize V2G technology, one is to realize bidirectional transformation on the pile, and the other is to realize bidirectional transformation in the car. Realizing two-way transformation on the pile is a way with the lowest threshold of market access, that is, I have two-way modules, which can be sold to the charging pile factory. Customers have no requirements for the development process and whether the factory has TS16949. However, the old generation believes that realizing it on the pile, one is the high system cost (car + pile), the other is the charging pile operation enterprise, which will not occupy its own charging space for a long time, What they want is the fast flow of vehicles above the charging position. To realize bidirectional transformation on the vehicle is to optimize the existing OBC. The R & D and manufacturing systems of the on-board power supply plant have met the requirements of the main engine plant, and the cost and time of realizing bidirectional transformation are the lowest

3. In the future, the charging pile is convenient for users to process data twice; High power development trend

the future direction is to go in the direction of high voltage and high power, which has been proposed by European car companies for a long time. The following is the road sign of Volkswagen:

the road sign of Volkswagen electric vehicle is to have a longer range and a shorter charging time, which is also confirmed in China. BAIC's eu260 was launched last year and upgraded to eu400 this year, with a significant increase in endurance mileage

the following figure shows the specific implementation method:

the way to reduce the charging time is to increase the voltage to 1000V and the charging current to 350A (Phoenix Contact has launched a 350A charging gun prototype), and the maximum system power to 350kW

recently, hundreds of people have discussed hot topics such as high-power charging and wireless charging. Teacher Ouyang Minggao's summary is very wonderful, especially the analysis of battery performance. 4. Sample inlay is enlightening. In any case, high-power charging is no longer a question of whether to do it, but how to do it. 70 especially in the field of cutting-edge new materials, 0V voltage platform may become a direction in the current transition period

if you look at the charging voltage range of various domestic models at present:

the current charging range of charging pile module is up to 750V, while the charging voltage of BYD C9 and K8 models has reached more than 800 Volts, and the demand for 950v high-voltage charging module is imminent
