The invention discloses a new energy automobile motor cooling system control method, and relates to the technical field of new energy automobiles, and the control method comprises the following steps: cooling system self-inspection; monitoring the temperature; comparing numerical values; the cooling system works, the rotating speed of the water pump and the rotating speed of the cooling fan are determined according to the selected cooling mode, the water pump and the cooling fan are independently controlled through corresponding controllers, and the cooling mode comprises a constant-speed control mode and a dynamic control mode. The motor controller has the advantages that the temperature control function of the motor and the motor controller can be met, the cooling system can be prevented from keeping high-power operation for a long time, energy consumption is reduced, the rotating speed of the motor and the rotating speed of the cooling fan can be adjusted in real time according to needs during dynamic control, and therefore the cooling effect is guaranteed, and the service life is prolonged. The alarm temperature is set, the motor can be stopped after the temperature of the motor and the motor controller exceeds the alarm temperature for a certain time, motor damage and loss expansion can be avoided, and the safety of the whole vehicle is guaranteed.

    本发明公开了一种新能源汽车电机冷却系统控制方法,涉及新能源汽车技术领域,本发明控制方法包括以下步骤:冷却系统自检;温度监测;数值比对;冷却系统工作,依据选定的冷却方式来确定水泵和散热风扇的转速,分别由相应的控制器对水泵和散热风扇进行单独控制,冷却方式包括定速控制方式和动态控制方式两种方式。本发明的优点在于:能够满足电机及电机控制器的温度控制作用,也能够避免冷却系统保持长时间高功率运转,减少能量消耗,在动态控制时能够根据需要对电机及散热风扇的转速进行实时调整,从而保证冷却效果,设置报警温度且在电机及电机控制器的温度超出报警温度一定时间后能够停止电机工作,可避免电机损坏,扩大损失,保证整车安全。
