A group of automotive bloggers in China recently conducted an extensive teardown of BYD’s second-generation Blade Battery pack over a livestream, drawing significant attention to the cell’s structural integrity and safety performance. Over a period of approximately six to eight hours, the team used heavy-duty tools— including angle grinders, pry bars, electric saws and hammers— to dismantle the sealed pack and access its individual cells.
According to footage and viewer reports, the dismantling process produced no visible smoke or fire, despite repeated cutting, grinding and impact testing. The teardown team noted the pack’s robust sealing methods, reinforced casing and integrated thermal materials, which together contributed to its resistance against the aggressive mechanical assault. Only minor workmanship issues were observed, such as uneven adhesive application around certain modules.
Online commentary around the livestream delved into BYD’s flash-charging battery technology and thermal management strategies under high-power charging conditions. Observers highlighted how the pack’s design balances rapid-charge capabilities with structural rigidity. The dismantling also reignited earlier debates over flash-charging system performance and safety, although no signs of thermal runaway were reported during the live session.
Some industry commentators raised concerns about the safety procedures used by the teardown team, pointing to an apparent lack of visible fire-suppression equipment and insulated protective gear. These critiques underscored the importance of adhering to professional dismantling protocols when evaluating high-energy battery systems.
Separately, BYD has acknowledged ongoing battery supply constraints as demand grows for its fast-charging electric vehicles. In particular, the Fang Cheng Bao Ti3 compact SUV— equipped with the upgraded Blade Battery— has become a notable example of the technology in action. Priced from 153,800 yuan (approximately 22,300 USD), the Ti3 supports a 10–70% recharge in about five minutes and a near-full recharge in roughly nine minutes under ideal conditions. Domestic sales of the model reached 5,206 units in April 2026, a 70.8% increase year-on-year, accounting for nearly one quarter of the brand’s monthly volume.
