The BYD sedan that was the first production vehicle to use the BYD Blade Battery was the BYD Han EV.
BYD publicly unveiled the Blade Battery in March 2020. Developed by BYD’s FinDreams Battery subsidiary, it uses lithium iron phosphate chemistry and a long, flat cell format intended to improve packaging efficiency, structural integration, and resistance to thermal incidents compared with older battery arrangements.
The Blade Battery was first integrated into the BYD Han EV, which went on sale in June 2020. That makes the Han the first production vehicle associated with the technology, rather than the BYD Dolphin, Seal, or Tang. Those models arrived later or adopted Blade Battery technology after its initial debut.
The Han is a large electric sedan positioned above BYD’s smaller passenger cars. Its launch helped establish the Blade Battery as a major part of BYD’s electric-vehicle strategy, although battery specifications can vary by market and trim. The name refers to the battery cells’ elongated shape, not to a separate charging system.
