Title:
ENERGY CONSUMPTION METHOD AND APPARATUS, AND WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/050780
Kind Code:
A1
Abstract:
An energy consumption method, comprising: acquiring converted electrical energy, wherein the converted electrical energy is generated by a winch system of a work machine carrying out potential energy-electrical energy conversion; under the condition that the work machine satisfies a target condition, on the basis of the converted electrical energy, acquiring residual electrical energy of the winch system, and on the basis of the residual electrical energy, acquiring a target rotating speed of an oil pump motor and a target opening degree of a proportional overflow valve in a hydraulic system of the work machine; and after the winch system is controlled to supply power to the hydraulic system, controlling the hydraulic system to consume the residual electrical energy on the basis of the target rotating speed and the target opening degree. The residual electrical energy of the winch system can be more accurately consumed by using the hydraulic system of the work machine without additionally configuring a device, the investment cost is lower, and the economy is better. Also provided are an energy consumption apparatus, a work machine, an electronic device, and a storage medium.
