The embodiment of the invention provides a control method for a thermal management system, an electric excavator and a controller. The heat management system comprises a hydraulic oil management system and an air conditioner warm air water heating system, and the air conditioner warm air water heating system comprises a first temperature sensor used for detecting the first outlet temperature of a warm air core. The first end of the first electric control valve is connected with the first water pump, the second end of the first electric control valve is connected with the warm air core body, and the third end of the first electric control valve is connected with the first heat exchanger. The first end of the second electric control valve is connected with the first heat exchanger, the second end of the second electric control valve is connected with the hydraulic return oil heating device. The hydraulic oil transfers heat generated by the hydraulic return oil heating device to the air conditioner warm air water heating system through the first heat exchanger, and the air conditioner warm air water heating system is heated through the hydraulic oil, the first electric heater and the warm air core.

    本申请实施例提供一种用于热管理系统的控制方法、电动挖掘机及控制器。热管理系统包括液压油管理系统和空调暖风水加热系统,空调暖风水加热系统包括第一温度传感器,用于检测暖风芯体的第一出口温度,控制方法包括:在第一出口温度满足第一低温条件的情况下,控制第一电控阀的第一端与第一水泵连接,第二端与暖风芯体连接,第三端与第一换热器连接,以及控制第二电控阀的第一端与第一换热器连接,第二端与液压回油加热装置连接,第三端与第一散热器连接,以使液压油将液压回油加热装置产生的热量通过第一换热器传递至空调暖风水加热系统,以通过液压油、第一电加热器以及暖风芯体对空调暖风水加热系统进行加热。
