Title:
BRAKING ENERGY CONSUMPTION CONTROL METHOD AND APPARATUS, WORK MACHINE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/011773
Kind Code:
A1
Abstract:
The present invention relates to the field of work machines, and provided thereby is a braking energy consumption control method and apparatus, a work machine, and an electronic device. The method comprises: acquiring an allowed recharging power of a battery, braking feedback power, and the rotational speed of a rotary motor; if it is determined on the basis of the allowed recharging power of the battery and the braking feedback power that the allowed recharging power of the battery does not meet the requirements of rotary braking, controlling a rotary pressure-retaining member to be opened; and on the basis of the rotational speed of the rotary motor, controlling the degree of opening of the rotary pressure-retaining member, so as to consume braking energy of electric rotation. Thus, when recharging is not allowed by the battery, the braking energy of the electric rotation can be promptly consumed by means of controlling the degree of opening of the rotary pressure-retaining member, thereby greatly reducing damage to a rotary apparatus caused by untimely consumption of the braking energy of the electric rotation, solving the problems of the rotary apparatus being easily damaged and the service life of the rotary apparatus being affected because the energy generated by the rotary braking cannot be promptly consumed when the battery does not allow recharging.
