AI Technical Summary
In the existing technology, the cooling fan of the electric vehicle drive motor cannot automatically find and maintain the lowest energy consumption operating strategy according to different temperature conditions and system status changes, resulting in energy waste or insufficient heat dissipation effect.
By acquiring motor temperature and ambient temperature information, and using a temperature duty cycle mapping table to dynamically adjust the duty cycle of the cooling fan, adaptive optimization control is achieved.
It achieves the automatic search and maintenance of the lowest total fan power consumption based on different temperature conditions and system status changes, thereby improving heat dissipation efficiency and energy management.
