Why can Wang Chuanfu be so convinced in 2018 that photovoltaic energy storage in electric vehicles must be the future？In 2003, BYD got the qualification to build cars, and BYD's real first mass-produced car, F3, officially rolled off the production line in April 2005. Yes, Wang Chuanfu never came for fuel cars. He started from the beginning. It is to make trams. In his eyes, electric vehicles must be the future, and the core of electric vehicles is power batteries. Photovoltaic, new energy vehicles, and energy storage power stations are just three carriers of batteries。From the beginning of the car, BYD has invested a lot of money and manpower to study new energy vehicles.。Understanding technology allows BYD to understand the future。Technology is king, innovation is the development philosophy that BYD adheres to。When BYD was building batteries, Wang Chuanfu was the one who knew the most about battery technology in the company.。And in addition to the admiration of technology, BYD's technology explosion can not be separated from its other advantages, vertical integration, vertical integration is difficult to do, BYD because of this model was once in a very big dilemma。The so-called vertical integration, is the industry's upstream and downstream all in their own hands。In 2003, Wang Chuanfu decided to bring the vertical integration model into the automotive industry.。Two years later, BYD F3 opened BYD's production line, and the joint venture model looks no different from it, the price is only half of the former, relying on vertical integration, relying on cheap。Over the next five years, F3 sales skyrocketed, surpassing 1 million units in 2010, during which it received a huge investment from Warren Buffett.。Wang Chuanfu also took advantage of the victory, bringing the vertical integration model into the then unformed photovoltaic and energy storage fields.。A deep understanding of technology has given BYD an advanced strategic prediction and confidence, and Wang Chuanfu's fascination with technology has brought BYD a strong technical culture, which is interdependent and indispensable.。Wang Chuanfu blew a cow in 2017, to be number one in the country in 2015, to be number one in the world in 2025, and the cowhide blew through in 2015, but the 2025 goal doesn't seem to be so far away。
