Apple's Secret EV Battery Partnership with China's BYD Revealed

Apple collaborated with BYD on advanced battery technology for its now-canceled car project, investing billions over several years.

Apple and BYD began their secret partnership in 2017, focusing on developing lithium iron phosphate (LFP) batteries for electric vehicles.
The collaboration aimed to create safer, longer-range batteries, with Apple providing expertise in battery packs and heat management.
BYD's Blade battery, now a key feature in its vehicles, was influenced by the partnership, though Apple holds no patents on the technology.
Apple invested approximately $1 billion annually in its car project, known as Project Titan, before canceling it in February 2024.
Insights from the battery development have contributed to other Apple technologies, including the Vision Pro headset and Neural Engine AI processor.
