The invention belongs to the technical field of vehicle driving, and discloses a special vehicle propelling system with a flywheel energy storage device. The special vehicle propelling system comprises an engine, an electric generator, an AC / DC electric power conversion module, a battery pack and the flywheel energy storage device, wherein the electric generator converts mechanical energy generated by the engine into electric energy; the AC / DC electric power conversion module is connected with the electric generator, rectifies three-phase alternating currents into direct currents and transmits the electric energy to a direct current bus; the battery pack transmits the electric energy to the direct current bus through a DC / DC electric power conversion module; the flywheel energy storage device is hung with the direct current bus through a DC / AC electric power conversion module; the direct current bus is connected with electric vehicle parts; the battery pack and the flywheel energy storage device together constitute an energy storage system of the propelling system to meet the needs of various working conditions of a vehicle platform. The special vehicle propelling system issmall in size and can be arranged conveniently and integrally. Compared with chemical batteries and super-capacitors, flywheel energy storage is adopted, the reliability is high, and the adaptive capacity to the environment is high. Special electricity needs of electromagnetic guns, electrothermal chemical guns and protection systems are met. The special vehicle propelling system plays a role inbalancing a vehicle grid system.
Description
technical field [0001] The invention belongs to the field of driving technology of a propulsion system of a special vehicle and the technical field of vehicle energy management, and relates to a propulsion system of a special vehicle with a flywheel energy storage device. Background technique [0002] With the demand for environmental protection and the problem of oil reserves becoming increasingly prominent, it is an important trend in the development of the world's automotive industry to develop energy-saving and environmentally friendly vehicles that use alternative energy sources to reduce environmental pollution. The automobile manufacturing industry has turned their attention to the development of electric vehicles. Finding new batteries with high energy storage density, short charging time and low price will determine whether electric vehicles or electric vehicles can have greater mobility and compete with gasoline vehicles. The flywheel battery can charge the flywhee...
