Abstract

The invention relates to a control system for a mileage adder of a pure electric automobile, which comprises the mileage adder, wherein the output end of the mileage adder is connected with the incoming line end of a high-voltage battery pack, the outgoing line end of the high-voltage battery pack is connected with a drive motor via an inverter, the drive motor drives the whole automobile to travel through a gearbox, and the mileage adder is respectively connected with three option switches which includes the options of manual startup/manual shutdown/automation. The invention further discloses a control method of the control system for the mileage adder of the pure electric automobile. In the invention, the electric quantity of the high-voltage battery pack can be automatically monitored in real time and that when the high-voltage battery pack needs to be charged and when the high-voltage battery pack is in a shutdown state can be judged. In a word, the invention achieves the power generation function of the mileage adder for the whole automobile, lengthens the duration mileage of the automobile, prolongs the service life of the high-voltage battery pack and has simple structure and convenient use.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a pure electric vehicle range extender control system and a control method thereof. Background technique [0002] Energy and the environment are necessary conditions for sustainable development. Reducing and eliminating dependence on oil is an urgent task related to global economic security and energy security. Research on energy-saving and environmentally friendly vehicles is an effective way to relieve energy pressure and reduce environmental pollution. One of the means. Due to the low specific energy and specific power of the existing electric vehicles, problems such as short mileage, long charging time, and short battery life of the existing electric vehicles have been caused. The traditional plug-in hybrid electric vehicle control system is complex and technically difficult. Contents of the invention [0003] The primary purpose of the present invention is to provide a p...
