Battery Technology

BYD's Blade Battery utilizes lithium iron phosphate (LFP) materials. Through CTCB (Battery-Body-Integration) technology, the battery is deeply integrated into the vehicle structure. This design ensures exceptional safety, passing the needle penetration test with a 50% increase in battery pack compressive strength. The battery achieves an energy density of 180Wh/kg, delivering over 700km range under CLTC conditions and exceeding 3,000 cycles of service life, supported by a lifetime warranty for the entire vehicle.

Motor Technology:
BYD employs its independently developed permanent magnet synchronous motor integrated into an eight-in-one electric drive system. This system consolidates eight modules including the drive motor and reducer into a single unit, achieving 30% volume reduction and 25% weight reduction. The motor delivers 97.5% efficiency with power density exceeding 4.5kW/kg. The dual-motor configuration delivers a maximum power output of 380kW, enabling the vehicle to break the 100km/h acceleration barrier within three seconds.

Electric Control Technology:

Built on the e-platform 3.0, this system integrates the industry's first domain control architecture, consolidating traditional distributed ECUs into four core modules with 30-fold computational power enhancement. The groundbreaking wide-temperature range heat pump system supports operation across-30℃ to 60℃ extremes, achieving up to 90% regenerative braking energy recovery. Additionally, the 800V high-voltage platform enables "5-minute charging for 150km range" and a rapid 15-minute fast-charging cycle from 30% to 80%.
