Among the legends in the automobile circle, Wang Chuanfu is the least like a car company, because he has always been based on the development and innovation of the new energy market, not limited to BYD's achievements and status.

He once said that "as an entrepreneur, money is no longer a big problem, and what he wants more is to serve the country through industry".

He promised that "fossil energy will be exhausted one day, so we need to change, use green methods and technologies, and dream a green dream."

It also made a headline, saying that "only 1% smart cars will be the means of transportation in the future, and the remaining 99% are all imagined".

There is no doubt that the domestic new energy market can achieve today's development, in addition to policy support, but also Wang Chuanfu's unwavering promotion. What he said has become BYD's brand vision.

Wang Chuanfu delivered a speech, and safety is a difficult problem for new energy vehicles.

65438+1October 1 1, China committee of 100 Forum on Electric Vehicles (2020) was officially held in Beijing Diaoyutai State Guesthouse. Wang Chuanfu, Chairman and President of BYD, attended the meeting and delivered a keynote speech.

He said that China is in a critical period of transformation from a "traditional automobile power" to an "electric vehicle power", especially in the next three to five years.

However, with the rapid development of new energy automobile industry, some safety problems have also been exposed.

According to the Report on Big Data Safety Supervision Results of National Supervision Platform for New Energy Vehicles, From May to July, 2065438+09, 79 safety accidents were found on the national supervision platform of new energy vehicles, involving 96 vehicles such as Weilai and Tesla.

In this regard, Wang Chuanfu proposed to "strengthen the construction of the industry safety standard system, especially in the early stage of the development of new energy vehicles, when it comes to safe power batteries, we need to be more cautious. 」

Looking back on the development of lithium batteries, mobile phone batteries and computer batteries have also gone through this stage. Later, with the establishment of industry safety standards, the battery safety problems were alleviated and the quality was controlled.

In China, commercial vehicles have a set of effective safety standards. Without this set of standards, when the electrification of public transport reaches 90%, safety problems should occur frequently.

But in fact, bus safety accidents are highly controllable, fire accidents are rare, and products are rarely questioned. The bus is equipped with lithium iron phosphate battery, which has excellent thermal stability and high safety.

Wang Chuanfu suggested, "Passenger cars should set higher safety standards with reference to commercial vehicles. Only by firmly holding the safety bottom line can the industry develop. 」

BYD mass-produced "Blade Battery", and the brand-new "Han" will be the first one.

In the development of new energy vehicles, Lydia has always placed safety in an extremely important position, and its "blade battery" has the characteristics of high safety and long life.

As the name implies, the blade battery is shaped like a blade. In fact, it is BYD's new generation lithium iron phosphate battery. Although lithium iron phosphate battery was once replaced by ternary lithium battery because of its low energy density in the past.

However, BYD started from lithium iron phosphate battery and never gave up the research and development of this battery. Finally, with the blessing of more than 300 patents, the new generation of blade batteries not only greatly improved the energy density and weight energy density, but also increased the design and safety.

A few days ago, the brand-new "Han" of the screen-brushing network will be the first model equipped with BYD's "blade battery". The new car will be officially launched in June, with a cruising range of 600 kilometers and a vehicle cruising range of more than one million kilometers.

As a heavyweight model to upgrade the matrix of the dynasty family series, the arrival of the new Han has made consumers full of expectations. In addition to the new Longyan design and blade battery that have been released, BYD's latest DiLink intelligent network connection system will also be applied to new cars.

It can be said that the "blade battery" and the brand-new "Han" will be another innovation for BYD in the face of the new energy market, and also products that highlight BYD's internal strength as a global leader in the new energy industry.

Can BYD start the second spring of the new energy market?

As we all know, due to the decline of subsidies, the new energy vehicle market is facing unprecedented challenges and life-and-death competition.

Yesterday, the China Automobile Association announced the annual production and sales data. In 20 19, the production and sales of new energy vehicles were12.42 million and12.06 million respectively, down by 2.3% and 4.0% respectively.

This is the first negative growth in recent ten years when China vigorously promoted new energy vehicles.

In this new form, it will be the only way for the new energy market to usher in the second spring by understanding the development of new energy vehicles, creating the same standards in the industry and bringing corresponding products.

In Wang Chuanfu's view, "the more adjustment, the more technological innovation, the more enterprise reform, and the more efforts. 」

Up to now, Lydia has applied for 28,000 patents worldwide, of which more than 654.38+700,000 were granted. From battery, motor, electronic control to IGBT power semiconductor, we have mastered the core technology of the whole industrial chain of new energy vehicles.

During the transformation, BYD launched the DiLink intelligent networking system, which opened 34/kloc-0 sensors and 66 control rights, realizing the opening of the automobile industry for the first time.

In 20 19, BYD won the largest electric bus order in Europe, Latin America and South Asia. At the same time, BYD sold 229,500 new energy vehicles in 2065,438+09, and won the national new energy vehicle sales champion for six consecutive years.

In 2020, standing in the second "10" of new energy development, with the establishment of industry standards, technological breakthrough and innovation, product innovation, driven by enterprises such as Wang Chuanfu and BYD, the new energy market will definitely return to the fast lane of development.
