The embodiment of the invention relates to the technical field of electrical control, provides power supply control equipment and a power supply control method of a vehicle-mounted air conditioner and an operation machine, and aims at solving the problem that in the prior art, when an engine of an operation machine such as a super-large excavator is in a parking state, idling operation is needed for refrigeration, and consequently oil consumption is high. The power supply control device of the vehicle-mounted air conditioner comprises an engine, a generator, a charger, a battery unit, a motor driver, a motor, a display unit and a controller. The controller is used for determining the required rotating speed of the motor and the required torque of the generator; in the parking state, the battery unit is used for providing electric energy for the motor driver, and the motor driver provides the electric energy for the motor so that the motor can rotate based on the electric energy to drive the compressor to work. In the driving state, the generator rotates based on the torque indicated by the charger to generate electric energy, the electric energy required by the motor is provided for the motor driver through the charger, and the remaining electric energy is provided for the battery unit for charging.
本申请实施例涉及电气控制技术领域,提供了一种车载空调的供电控制设备、供电控制方法及作业机械,用以解决现有技术中作业机械如超大挖掘机发动机在驻车状态下,需怠速运转进行制冷造成油耗较高的问题。车载空调的供电控制设备包括发动机、发电机、充电机、电池单元、电机驱动器、电动机、显示单元以及控制器;控制器,用于确定电动机的需求转速以及发电机的需求转矩;在驻车状态下,电池单元用于为电机驱动器提供电能,电机驱动器将电能提供给电动机,以使电动机基于电能转动,带动压缩机工作。在行车状态下,发电机基于充电机指示的转矩转动产生电能,通过充电机将电动机的需求电能提供给电机驱动器,并将剩余电能提供给电池单元进行充电。
