The invention relates to a rotating speed control system for an integrated thermal management electronic fan of a pure electric vehicle. The rotating speed control system comprises a signal acquisition device and an integrated temperature controller. The invention further relates to a rotating speed control method for the integrated thermal management electronic fan of the pure electric vehicle. The method comprises the steps that control model input signals are collected; determining a plurality of different electronic fan rotating speeds according to the control model input signal; selecting the highest rotating speed from the rotating speeds of the electronic fans as the reference rotating speed of the electronic fans; and correcting the electronic fan reference rotating speed to obtain the final rotating speed of the fan. The fans are managed as a whole, the purchase cost of the fans is reduced, the rotating speed of the fans is distributed more reasonably, and the energy consumption of the whole vehicle is further reduced; frequent start and stop are prevented to protect the fan, and the service life of the fan is prolonged; and the uncomfortable influence of fan rotating speed sudden change on a user is avoided.

    本发明涉及纯电动车集成热管理电子风扇转速控制系统,包含信号采集装置、集成温控器。本发明还涉及纯电动车集成热管理电子风扇转速控制方法,包含步骤:采集控制模型输入信号;根据控制模型输入信号确定多个不同的电子风扇转速;从电子风扇转速中选出数值最高的一个,作为电子风扇基准转速;对电子风扇基准转速进行修正,得到风扇最终转速。本发明统筹管理风扇,实现了减少风扇采购成本,也更加合理分配风扇转速,并进一步降低了整车能耗;实现了防频繁启停以保护风扇,延长了风扇使用寿命;避免了风扇转速突变带给用户的不适影响。
