AI Technical Summary
Existing control strategies for new energy vehicle power systems are not suitable for high-temperature and dusty conditions, resulting in insufficient power output, abnormally high energy consumption, poor system stability, and a lack of integrated and coordinated control modes.
By collecting environmental and power system parameters in real time, a special control mode for high-temperature sand and dust is identified. Dynamic calibration is performed based on a four-dimensional calibration model of temperature-torque-power-efficiency. Combined with graded thermal management collaborative control, energy recovery buffer control and system closed-loop stability regulation, the coordinated control of power output, thermal management and energy recovery is realized.
In high-temperature and dusty environments, the power attenuation rate is ≤7.5%, the power transmission efficiency is ≥94.0%, significantly reducing the increase in energy consumption and the fluctuation rate of SOC, improving power performance and operational stability, and broadening the applicable scenarios for vehicles.
