Title:
TEMPERATURE CONTROL METHOD AND MODULE FOR HEAT DISSIPATION SYSTEM OF NEW ENERGY COMMERCIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/000366
Kind Code:
A1
Abstract:
A temperature control method and module for a heat dissipation system of a new energy commercial vehicle. The method comprises: determining an operating state of a driving motor according to the temperature of the driving motor, the torque of the driving motor, the rotational speed of the driving motor, the temperature of a cooling liquid, the temperature of ambient air, an output voltage of a motor controller, and an output current of the motor controller; and calculating an optimal target temperature of the driving motor according to a control function associated with a target temperature steady-state control function by an energy optimization control function and outputting a corresponding PWM fan control signal. The temperature control method and module for a heat dissipation system of a new energy commercial vehicle achieve optimal balance between heat loss of a driving motor and power consumption of a heat dissipation system by optimizing the output of the heat dissipation system, thereby reducing the sum of the heat loss of the driving motor and the power consumption of a cooling system while the driving motor operates in a safe temperature interval, facilitating the improvement of the energy utilization efficiency of a new energy commercial vehicle, and implementing energy conservation and emission reduction.
