The Future of Electric Mobility
BYD e-Platform 3.0
e-Platform 3.0 is BYD’s third-generation, all-in-one electric vehicle architecture — engineered for safety, efficiency, performance, and intelligent integration.
Built from the ground up for EVs (not adapted from ICE platforms), e-Platform 3.0 integrates the battery, motor, electronics, and thermal systems into a unified, modular ecosystem. This allows for lower center of gravity, more cabin space, faster charging, and smarter driving dynamics.
Key Innovations of e-Platform 3.0
Integrated 8-in-1 Powertrain
Combines motor, reducer, inverter, DC-DC converter, OBC, PTC, compressor, and MCU into one compact unit — reducing weight by 10% and boosting efficiency to 97.5%.
800V High-Voltage Platform
Enables ultra-fast charging: 10–80% in as little as **15 minutes** (on compatible models like BYD Seal).
Integrated Thermal Management
Unifies battery, cabin, and powertrain cooling/heating for optimal range in extreme climates — even at -30°C.
Smart Domain Controller
Centralized OTA-upgradable architecture for DiPilot, infotainment, and vehicle control — enabling continuous improvement over time.
Why e-Platform 3.0 Matters
Lower Center of Gravity
Flat Blade Battery floor + compact drivetrain = sportier handling & reduced rollover risk.
More Usable Space
No transmission tunnel or engine bay = more legroom, cargo space, and flat floors.
Higher Efficiency
Up to 10% more range per kWh compared to previous platforms.
