Rare earth permanent magnet silent diesel generator set for pure electric vehicle range extender

Abstract

The invention provides a rare-earth permanent magnet ultra-silence diesel generating set for a range extender of a battery electric vehicle. The rare-earth permanent magnet ultra-silence diesel generating set comprises a rare-earth permanent magnet ultra-silence diesel generator, a postprocessor, an expansion water tank, a heat radiation module, a control system and an oil tank. The postprocessor is used for purifying waste gas exhausted out of the rare-earth permanent magnet ultra-silence diesel generator. The heat radiation module is used for removing surplus heat of the rare-earth permanent magnet ultra-silence diesel generator. The control system controls starting, shutdown, loading and unloading of the rare-earth permanent magnet ultra-silence diesel generator and protects reliable running of the rare-earth permanent magnet ultra-silence diesel generator. The expansion water tank is used for adding cooling liquid into a cooling system in the rare-earth permanent magnet ultra-silence diesel generator or unloading too high pressure of the cooling system. According to the generating set, noise can be effectively isolated, the experience of passengers for taking the battery electric vehicle can be improved, oil consumption can be effectively reduced, tail gas emission of the battery electric vehicle is controlled, a heat radiation system is improved, and the service life of the generating set is prolonged.

Description

technical field [0001] The invention relates to the generator technology of an electric vehicle, in particular to a rare earth permanent magnet silent diesel generator set used for a range extender of a pure electric vehicle. Background technique [0002] Common electric vehicle batteries can be divided into two categories, namely storage batteries and fuel cells. Batteries are suitable for pure electric vehicles and can be classified as lead-acid batteries, nickel-based batteries (nickel-hydrogen and nickel-metal hydride batteries, nickel-fu and nickel-zinc batteries), sodium szlig batteries (sodium-sulfur batteries and sodium Nickel chloride battery), secondary lithium battery, air battery and other types. Fuel cells are dedicated to fuel cell electric vehicles and can be divided into alkaline fuel cells (AFC), phosphoric acid fuel cells (PAFC), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC), proton exchange membrane Fuel cell (PEMFC), direct methanol ...

Problems solved by technology

However, in the actual use of the hybrid solution, it is found that the vehicle is noisy and cannot effectively control the emission of the vehicle, so it deviates from the original intention of electric vehicles to be clean and environmentally friendly
