July 25, Tesla global vice President Wu Bixiang in a narrow reception room in a hotel in Shenzhen, facing the controversy in the whirlpool, with a smile to answer the media's most incisive questions.

Wu Bixiang to the 21st century economic reporter confirmed that Tesla's stance on independent charging has been reversed, "we have decided that when China's standards are determined, we will change to China's charging standards." It was not adopted because China's DC charging standards are not perfect. ”

Tesla changed the standard, the core purpose is to allow owners to obtain convenient charging. But at present, Tesla has built only 7 super charging stations in China, and still has a distance from the convenient charging system.

Currently there are four major electric vehicle charging standards, China, Japan, Tesla and European and American standards respectively. With the increasing support of electric vehicles in various countries, charging station construction is more and more, national standards and Tesla has been face-to-face direct conflict.

Abandoning standard control overseas

Musk from last year, large-scale acceleration super charge station construction. 94 recharging stations were built in North America in May this year, and the super charging station is expected to cover 80% of the population in the United States by 2015, covering 98% of the U.S. population, and 20 recharging stations in Europe.

But this model allows Tesla to play almost as a game of global government power. In the face of State Grid, Southern power grid and so on the overall layout of state-owned enterprises, to rob China to charge the market, control standards, Tesla has no hope at all, and Tesla also burdened with public opinion and industry "heterogeneous" pressure.

The final logic of the Tesla team in China was to adopt national standards and give up control of the charging standard. The beneficial effect is that Tesla owners can use the huge charging network built up by the Chinese government to charge, and Tesla to boost sales.

In other parts of the world, Tesla also gave up control of the standard. "We use local standards in every country, and China is just one of them." Wu said that Tesla's implementation of the plan is premised on the introduction of China's draft DC charging standards. China's current charging standards are not perfect. The physical interface is unified, but the charge communication also waits for some parameters to be determined. ”

However, such waiting in China Electric Power Enterprise Federation Standardization Center Deputy Director, energy industry electric vehicle charging Facilities Standardization Technical committee Secretary General Liu Yongdong seems unreasonable. "There will be some revisions on the power agreement, but the parameters are small and the changes are minor," he said. So this is not the main reason why some companies do not adopt current standards. ”

Tesla may face technical problems: first, the modification of the power protocol involves the internal system of Tesla products, which is more complex; Tesla battery capacity is large, charging voltage high, current large, the change will greatly increase the charge time, Tesla's original range of long mileage, short charge time advantage was broken.

In this situation, consumers are not required to buy high-capacity batteries of electric vehicles, it is very questionable. So Tesla is plotting to launch a lower-priced model III, with a much lower battery capacity and mileage.

How Tesla sees "electronic cars"

July 25, Tesla built a super charging station in Shenzhen Longhua New district, plus Beijing 2, Shanghai 3, Hangzhou 1, Tesla in China has 7 super charging station, the end of the year will be built in Guangzhou.

But Wu Bi Sora did not reveal Tesla's number of charging stations in the next few years, "if Tesla is fast and GB compatible, the convenience of recharging will increase the geometric multiples, the number of Tesla super charging stations will not be that important." ”

The problem is that the owners of the Tesla models have been bought to recharge their batteries after the standard changes. If there is no corresponding solution, Tesla owners face the contradiction is: first, only in the standard before the establishment of the charging station charging, the convenience of charging will not be improved over time; the second is to find Tesla to return the car, or the car's internal charging standards. Tesla has no detailed plan for this.

Although the future is unpredictable. But Wu Bixiang from Tesla's own technical features, the problem may be more convenient to solve than the imagination. "Tesla is in fact not a mechanically based car, but an electronic car based on a computer system, and many upgrades we only need to adopt a remote system upgrade." ”

Wu Bixiang means, the possible solution is through technical processing, can realize already in use of the model and GB compatible. However, no matter how the changes, Tesla's existing owners must face a slow DC-charging speed, up to 85 degrees of power of the maximum capacity of the battery has long been part of the battery idle possible.

Tesla's biggest attraction to the market is innovation. Wu Bixiang that Tesla's innovation is that it is not really a car, but an "electronic product." "The owner's experience with Tesla will continue to be new, because the system upgrades will bring different feelings, the novelty of this innovation will never end, and will get better, and the traditional car driving experience, as the mechanical aging worse." ”

However, an international brand of electric vehicle research and development engineers to the 21st century economic reporting reporter said: "We are the biggest concern for Tesla, the remote control system upgrade, can be in the car owners do not know the effect of the upgrade, directly lead to a complete change in the driving experience, car owners may not adapt." At present, many owners of automatic driving is completely unacceptable, even some small innovation, it will take a long time to persuade owners to accept, such as automatic braking system. ”

Traditional car brands are cautious about the application of new technologies, not only to demonstrate the acceptability of the market, but also to carry out a hundreds of thousands of-kilometer mileage test for new technologies. But Tesla's electronic thinking, like Apple's mobile phone, has a far more extreme test than the strength of its mobile phone and the harsh environment it uses.

In this situation, security and reliability are difficult to be guaranteed as traditional cars. But Wu Bixiang put forward another vantage point, "the traditional car to maintain, our car is almost no maintenance, like a mobile phone to upgrade it." ”

Tesla's security questions are more than that, and 360 companies recently announced that they have cracked the Tesla's system, using computers to control some of Tesla's functions. Wu Bixiang does not deny: "We have communicated with 360 companies and discussed cooperation mechanisms." Tesla is a computer system, there will be loopholes, we welcome those who help us to find loopholes, we will cooperate with them. ”
