Abstract

The embodiments of the invention provide a power take-off control system, method and device, electronic equipment and a storage medium, and relates to the technical field of vehicle manufacturing. Thepower take-off control system comprises an energy storage device which is correspondingly connected with a hydraulic system and a hydraulic pump through hydraulic oil ways and used for exchanging energy with the hydraulic system and the hydraulic pump; and a controller is correspondingly connected with a motor, the hydraulic system and the energy storage device through a control circuit and usedfor receiving working state parameters of the hydraulic system and the energy storage device and controlling the motor and the hydraulic system to act. Through energy supply of the energy storage device, energy supply of loading action of a crane is guaranteed, the motor only needs to be started during loading action without being in a working state for a long time, the electric energy is saved, and the problems that the electric energy utilization rate of a battery is low, the service life of the battery is shortened, and the use cost is greatly increased due to the fact that the motor of anexisting electric crane is in the working state for a long time are solved.

Description

technical field [0001] The present application relates to the technical field of vehicle manufacturing, and in particular, to a power take-off control system, method, device, electronic equipment, and storage medium. Background technique [0002] When the power take-off operation of the existing electric vehicle crane is performed by the power take-off system, the motor needs to continue to work to provide power for the hydraulic system. , the motor runs at a fixed speed (idle speed) in order to provide hydraulic energy for the hydraulic system to build pressure in time. [0003] The characteristics of the existing electric cranes are that the power battery is expensive and the loading capacity of the battery is limited, and the limited battery capacity must also take into account the mileage and working time of the crane. In addition, the operating conditions of the electric crane are basically low frequency. The job interval time is greater than the job time. [0004] Ba...
