<\/p>\nApple worked with Chinese carmaker BYD for years as part of its now-cancelled car project, developing long-range batteries that helped lay the groundwork for technology used today, according to people familiar with the situation.<\/p>\n
Apple and the Shenzhen-based company teamed up around 2017 to build a battery system using lithium iron phosphate cells, said the people, who asked not to be identified because the effort has not been disclosed. The technology was designed to be longer-range and safer than typical electric-vehicle batteries at the time.<\/p>\n
Though Apple does not own any of the technology used in BYD\u2019s current Blade batteries, the partnership shows just how far the iPhone maker went in its efforts to produce a car. The tech titan spent roughly US$1 billion a year over the past decade on the vehicle project \u2013 often seen as one of the company\u2019s \u201cnext big things\u201d \u2013 before scrapping it in February<\/p>\n
The technology that Apple developed with BYD would have been highly customised for the once-planned vehicle, according to the people. As part of the secret partnership, Apple engineers brought expertise in advanced battery packs and heat management, they said. BYD contributed manufacturing know-how and advancements using lithium iron phosphate cells \u2013 better known as LFP.<\/p>\n

<\/div>Spokespeople for Apple and BYD declined to comment on the joint battery work. But BYD said in an emailed statement that \u201cthe concept for the Blade battery originated with BYD engineers, who independently developed this LFP Blade battery. BYD holds complete property rights and patent rights for the Blade battery\u201d.<\/p>\n
Today, BYD\u2019s entire car line-up is powered by the Blade system, which uses a battery pack design that people involved in its development say was informed by lessons from the Apple work.<\/p>\n<\/section>\n The seeds of Apple\u2019s BYD collaboration were planted about a decade ago, when the US company was seeking core technologies for its car. BYD engineers previewed early versions of the Blade battery to Apple executives, who admired the technology\u2019s safety and energy storage capabilities. Apple ultimately sought customisations that could enhance the range of an EV, the people said.<\/p>\n At the time, Cupertino, California-based Apple had already been working on several different batteries, using elements like nickel and alkaline. It had also been investing millions of dollars in battery pack design and engineering to squeeze in as many cells as possible. The two companies sought to combine the separate pack and cell efforts to produce a safe, long-range battery system for the Apple vehicle.<\/p>\n On the Apple side, the tie-up was led by Alexander Hitzinger, a former senior Volkswagen and Porsche executive who oversaw product design for the car project from 2016 to 2019. The company also had enlisted Mujeeb Ijaz, a veteran of the failed American battery start-up A123 Systems who worked at Apple from 2014 to 2020.<\/p>\n Ijaz oversaw a team of about 50 battery engineers working on the project. His counterpart at BYD was Michael He, vice-president of the company\u2019s battery business.<\/p>\n The Blade is now a signature feature in BYD cars \u2013 and a major selling point. The company used its improved range, relative safety and lower cost to generate sales of 3 million electric and hybrid vehicles in 2023, up from 179,054 three years earlier.<\/p>\n It is now the biggest carmaker in China by sales and briefly surpassed Tesla to become the top seller of EVs globally. BYD founder and Chairman Wang Chuanfu, a battery engineer himself, is a billionaire.<\/p>\n Despite years of working with BYD, Apple backed away from the partnership and considered systems from other battery makers, the people said. The overall car project suffered numerous delays, and the economics of the EV business eventually proved too daunting.<\/p>\n When Apple cancelled the car project, it marked a rare high-profile failure for the world\u2019s most valuable company. But the decadelong endeavour did prove useful in some ways. Beyond the battery insights gleaned from the effort, it helped with the development of products such as the Vision Pro headset and the Neural Engine AI processor now present in most Apple devices. The work also has contributed to the company\u2019s nascent push into robotics.<\/p>\n![\"A](\"https:\/\/img.i-scmp.com\/cdn-cgi\/image\/fit=contain,width=1024,format=auto\/sites\/default\/files\/d8\/images\/canvas\/2024\/10\/17\/66fc1caf-8e8a-42be-a8b1-573af67b92ce_686e78c9.jpg\" "\\"A")
