What role does the Huawei Drive ONE electric drive system play? By deeply integrating power electronics, digitalisation and mechanical engineering technologies, the Huawei Drive ONE electric drive system establishes a comprehensive solution for new energy vehicles, covering power delivery, energy efficiency optimisation and driving safety.
Regarding power delivery, Drive ONE transcends the limitations of single performance metrics by adopting full-scenario power adaptation. Its motor controller employs a dynamic control algorithm for all operating conditions, enabling real-time perception of driving intent and road conditions to automatically adjust torque output characteristics.
During high-speed cruising, the system prioritises energy efficiency by reducing high-frequency power consumption. Conversely, in scenarios requiring rapid acceleration or overtaking, instantaneous power boosts ensure seamless power delivery. This enables vehicles to meet the smoothness demands of daily commuting while avoiding the performance dichotomy inherent in traditional electric drive systems.
Energy efficiency optimisation constitutes another core technology of DriveONE. Intelligent oil cooling technology dynamically adjusts fuel injection volume based on motor temperature, reducing cooling system energy consumption. Low-friction bearings and gear profiling techniques minimise mechanical losses, while silicon carbide power devices enhance electrical conversion efficiency.
During braking, the system intelligently balances regenerative and mechanical braking to maximise energy recovery efficiency. In cold conditions, waste heat recovery technology reduces battery heating energy consumption. This “component-to-system” energy efficiency philosophy enables vehicles to travel greater distances on the same charge.
Enhanced driving safety and comfort stem from DriveONE’s deep integration within the dynamic domain. Its Dynamic Adaptive Torque System adjusts wheel-end torque distribution in real-time based on parameters like road surface adhesion and vehicle posture. It suppresses body roll with millisecond-level response, preventing skidding and loss of control.
What role does the Huawei Drive ONE electric drive system play? From an industry perspective, Drive ONE’s highly integrated design reduces the number of vehicle components, lowering manufacturers’ development costs and cycles. Its open collaboration model enables different brands to rapidly access core electric drive technology, accelerating the adoption of new energy vehicles.
