Electric drive loading machine power system, power control method and electric drive loading machine
The invention provides an electric drive loading machine power system, a power control method and an electric drive loading machine, and relates to the technical field of electric drive loading machines. The electric drive loading machine power system comprises a master controller, a power energy subsystem and an electromotor. The power energy subsystem and the electromotor are connected with themaster controller. The power energy subsystem comprises a flywheel and a power battery. The power battery is used for providing conventional required power. The flywheel is used for carrying out flywheel energy storage so as to provide peak value required power. The power energy subsystem is used for transmitting the conventional required power and/or the peak value required power to the electromotor, so that the electromotor provides power for the electric drive loading machine. The size of the loading machine is reduced, meanwhile, the high energy density of the power battery and the high power density of flywheel energy storage are fully utilized, electric energy is provided for a long time, and the energy utilization rate is increased; and the technical requirement of releasing high power within a short time to resist impact loads can be met, and safety of the loading machine is improved.
本发明提供了一种电驱装载机动力系统、动力控制方法和电驱装载机，涉及电驱装载机技术领域，电驱装载机动力系统包括：主控制器、动力能源子系统和电动机；动力能源子系统和电动机均与主控制器连接；动力能源子系统包括飞轮和动力电池；动力电池用于提供常规需求功率；飞轮用于进行飞轮储能以便提供峰值需求功率；动力能源子系统用于将常规需求功率和/或峰值需求功率传送至电动机，以使电动机为电驱装载机提供动力，本发明在减小了装载机体积的同时，充分利用动力电池的高能量密度以及飞轮储能的高功率密度，实现了长时间提供电能，提升了能源利用率，并且也可以在较短时间释放大功率抵抗冲击负荷的技术要求，提高了装载机的安全性。
