Application method of hydraulic energy storage system of new-energy electric heavy-duty mine truck

Abstract

The invention discloses an application method of a hydraulic energy storage system of a new energy electric heavy-duty mine truck. The method comprises the following steps: S1, mounting components ofthe hydraulic energy storage system of the heavy-duty mine truck, namely mounting the components of the hydraulic energy storage system of the heavy-duty mine truck on a heavy-duty mine truck body according to mounting requirements; S2, charging energy to an energy accumulator in the hydraulic energy storage system of the heavy-duty mine truck; and S3, converting the hydraulic energy into electricenergy, and driving a hydraulic generator to operate through the energy accumulator, so as to convert the gravitational potential energy generated when the heavy-duty mine truck goes uphill and downhill into the electric energy. When the mine dump truck runs, gravitational potential energy generated when the truck goes uphill and downhill can be converted into electric energy, the potential energy can be converted into the electric energy when the truck goes uphill and downhill in this way, huge electric energy loss generated when the electric heavy-duty truck goes uphill can be made up for,and the endurance capacity of the heavy-duty truck going uphill is improved.

[0002] The hydraulic energy storage system can convert the energy in the system into compression energy or potential energy for storage. When the system needs it, the stored energy can be released to replenish the system. The hydraulic energy storage device is mainly used in the hydraulic system for system pressure maintenance, To ease the impact pressure, absorb the pulse pressure and act as an emergency energy source, the existing mine dump truck is generally equipped with a hydraulic energy storage WEC power generation system to cooperate with the power supply system of the mine dump truck. However, the existing hydraulic energy storage WEC power generation system Only the potential energy of the vehicle when going downhill and braking can be converted into electrical energy, but the gravitational potential energy of the vehicle when going uphill cannot be converted into electrical energy. Therefore, we propose a new energy electric heavy-duty mining vehicle hydraulic energy storage system application method
