Abstract

The embodiment of the invention discloses a multi-power-source engineering machinery energy management system, a method, a device and a storage medium. A second energy management unit in the system is used for controlling a first power storage battery system and a second power storage battery system to alternately supply power to a load; and a first energy management unit is used for controlling the range extender to charge the first power storage battery system or the second power storage battery system when the first power storage battery system or the second power storage battery system is idle. The independent power storage battery system is adopted to alternately supply power to the load, the range extender charges the power storage battery system when the power storage battery system is idle, the frequency of frequent charging and discharging of the power storage battery system is reduced, the service life of the power storage battery system is prolonged, the range extender does not directly supply power to the load, the range extender can stably work in an efficient energy-saving area, the working efficiency of the range extender is improved, and energy consumption is reduced.

Description

Technical field [0001] The present application relates to the field of construction machinery, and in particular, there is a multi-dynamic source engineering mechanical energy management system, method, device, and storage medium. Background technique [0002] Construction machinery is an important part of the equipment industry. It is the mechanical equipment necessary for the construction of earth and stone construction projects, road construction and maintenance, flow-loaded and unloading operations and various construction projects required for various construction projects. [0003] At present, the incremental mixed power construction machinery is based on pure electric drive, increasing internal combustion engine to power battery charging or direct driving motor to increase the engineering mechanical work, compared to a single pure electric drive construction machinery has endurance mileage Longer advantage. [0004] However, existing increase-run hybrid engineering machine...
