BYD: Developed From Batteries, Made Electric Cars

- Jan 03, 2020-

In June this year, at the shareholders' meeting held in Shenzhen's Pingshan headquarters, Wang Chuanfu, Chairman and President of BYD's Board of Directors, dropped a bomb. He believes that Tesla has played an excellent role in promoting pure electric vehicles and cultivating consumer habits. However, once household consumption starts, BYD can build Tesla in minutes.


Tesla founder Elon Musk also responded to this in a subsequent visit: I don't think BYD is our competitor. But he quickly added that not only BYD, other electric vehicles including Nissan Leaf, GM Volt and Ford's Fusion are not comparable to Tesla because everyone's positioning is different.


For the tepid electric vehicle market, Tesla is like a long-awaited stimulant, and BYD is indeed the most experienced in Chinese automobile companies' research on electric vehicles. At present, some positive changes are taking place in the field of electric vehicles, and the market is happy to see such a confrontation.


Since the official launch of pure electric vehicles in 2010, BYD's main focus has been in the field of taxis and buses, but at the BYD World-Class Technology Conference in September, Wang Chuanfu officially announced that he is currently developing a pure electric super named E9. Sports cars will be targeted at the personal market as soon as 2015. He claims that the 0-100km / h acceleration of this product takes only 3.9 seconds, which is faster than the current 4.4 seconds of the Tesla ModelS.


If this plan can be realized, BYD's competition with Tesla will no longer just be verbal.


The biggest difference between a pure electric vehicle and a traditional car is that its power system is composed of a battery, a battery management system, and an electric motor. One of the core indicators is the energy density and safety of the battery.


Although BYD started with battery manufacturing, it also largely depends on the evolution of upstream battery material technology.


General Motors released the EV1 in 1996, which was the first electric car produced in large quantities by a large company. It was equipped with 32 lead-acid batteries with a total of 16KW / h, and two 42KW motors for a single charge. The ideal endurance can reach 96 kilometers. Lead-acid batteries are low-priced, but relatively heavy. The EV1 photovoltaic cell weighs nearly 500 kg and has a short cycle life. Although most of the electric vehicles still use lead-acid batteries for a long time to come, major manufacturers have been looking for better alternatives.
