New energy mining automobile electrical system

Abstract

The invention provides a new energy mining automobile electrical system. An engine is connected with an electric generator and then connected to an electric generator controller. The system further comprises an automobile wheel steering system and an automobile jacking system. The electric generator controller and a hydraulic motor controller are in control connection with a four-in-one integratedcontroller. An automobile traveling system is further connected to the four-in-one integrated controller and finally connected to a battery module. The battery module provides power for a whole automobile through the four-in-one integrated controller. When the state of charge SOC of a battery is lower than 45%, the engine drives the electric generator to generate current, the current is directlyinverted and integrated through the four-in-one integrated controller, meanwhile, the current is supplied to a main drive controller, the battery is assisted in conducting drive control on a main drive motor, and finally the whole automobile is driven. When the percent of the state of charge SOC of the power battery is larger than a set value, the engine stops working. When the automobile travelsdownhill again, the engine stops working, a new round of electric quantity recovery work starts, the recovery work is conducted in circles, so that a fuel and energy saving purpose is achieved, and the fuel consumption is saved by 50% to 70% compared with that of a traditional mining automobile.

Description

technical field [0001] The invention relates to an electrical system of a mining vehicle, in particular to an electrical system of a new energy mining vehicle. Background technique [0002] The traditional mining vehicle power system uses a diesel engine as the power of the vehicle. Due to the harsh roads and mines used by mining vehicles, most open-pit mining areas are operated on ramps. Most of the mining costs are consumed in fuel, resulting in energy loss. Serious consumption and environmental pollution. [0003] The introduction of new energy mining vehicles, especially the use of electric mining vehicles, requires the design of an electrical control system to adapt to the comprehensive utilization of power for electric mining vehicles. Contents of the invention [0004] In order to adapt to the comprehensive utilization of the power of the electric mining vehicle, the present invention proposes a supporting design of an electrical control system, which is a new ener...
