Wang Chuanfu founded BYD on 10 February 1995 in Buji Town, Longgang District, Shenzhen, with an initial capital of 2.5 million yuan and a team of approximately 20 people. Wang, then 29 years old, had previously worked as a vice supervisor at the Beijing Nonferrous Research Institute, where he observed Japanese battery manufacturers shifting from nickel-cadmium to higher-value nickel-metal hydride and lithium-ion batteries. He identified a cost arbitrage opportunity and moved to Shenzhen with his cousin Lu Xiangyang to establish BYD as a rechargeable battery manufacturer.
BYD's early competitive advantage was a redesigned manufacturing approach that substituted manual labour for the capital-intensive automated processes used by Japanese competitors. This reduced unit costs by approximately five to six times compared to Japanese rivals. By 1996, BYD had secured an order from Sanyo, marking its entry into the global battery supply chain. By 1997, amid the Asian financial crisis, Philips, Panasonic, and Motorola had all become major clients.
BYD expanded internationally early, opening a branch in the Netherlands in 1998 and establishing BYD America Corporation in 1999. By July 2002, BYD had become the world's leading nickel-cadmium battery manufacturer, surpassing Sanyo and accounting for approximately 65% of global production. In September 2002, BYD completed an initial public offering on the Hong Kong Stock Exchange.
Shortly after its Hong Kong IPO, BYD made a pivotal strategic move: in January 2003, the company acquired Xi'an Qinchuan Automobile, a small state-owned vehicle manufacturer, from defense conglomerate Norinco. The acquisition was controversial with shareholders, as it had not been disclosed in the IPO prospectus, but Wang Chuanfu's intention was to develop battery-powered electric vehicles using BYD's existing battery expertise.
BYD's first cars were conventional petrol vehicles. The BYD F3, a compact sedan, began production in April 2005 and gained market share through competitive pricing. The company produced its first plug-in hybrid vehicle, the BYD F3 DM, in 2008, and its first battery electric vehicle, the BYD e6, in 2009.
In September 2008, MidAmerican Energy Holdings, a subsidiary of Berkshire Hathaway, invested approximately 230 million US dollars for a 9.89% stake in BYD at HK$8 per share. Warren Buffett credited the investment to Charlie Munger, Berkshire's vice chairman. The investment proved highly profitable: Berkshire began gradually reducing its stake in 2022 as BYD's share price had risen substantially, and by September 2025, Berkshire had completely exited its position, generating a return of approximately 3,890%.
In June 2011, BYD listed on the Shenzhen Stock Exchange, raising approximately 1.42 billion yuan in a secondary offering. Between 2017 and 2019, BYD experienced a sharp decline in net profit, falling to just 1.6 billion yuan in 2019 as automotive sales stagnated. Wang Chuanfu described 2019 as the company's "darkest moment," yet the company continued investing 8.4 billion yuan in research and development that year.
The turnaround came in 2020. BYD introduced the Blade battery, a lithium iron phosphate cell with a distinctive structural design that improved safety and energy density. The Blade battery was first used in the BYD Han, a premium electric sedan, and was subsequently adopted across BYD's vehicle lineup. In the same year, BYD spun off four automotive component manufacturers under the FinDreams brand, with the intention of supplying parts to third-party automakers.
From 2020, BYD's vehicle sales grew dramatically, driven by the rapid expansion of the Chinese NEV market and the company's expanding export program. In March 2022, BYD ended production of purely internal combustion engine vehicles, becoming the first major global automaker to do so. In 2023, BYD introduced two new premium automotive brands, Yangwang and Fangchengbao, targeting the high-end and off-road segments respectively.
In November 2024, BYD commemorated its 30th anniversary and the production of its 10 millionth new energy vehicle. In the second quarter of 2025, BYD's quarterly net profit fell 29.9% year-over-year to 6.4 billion yuan, as vehicle sales in its home market slowed amid the Chinese government's campaign against automotive price wars. Despite the domestic slowdown, BYD continued to expand internationally, dominating new car sales in Singapore with over 20% market share in 2025.
