Abstract

The invention discloses an electric vehicle distributed energy supply system and work method for the same. The system comprise an energy management module, a power battery and a power follower set, wherein the power follower set is formed by two or more than two power followers; each power follower has a whole vehicle power following function; the energy management module is electrically connected with the power battery, the power followers, an electric vehicle driving system and a whole vehicle control unit. Different types of energy supplies can be combined to work according to driving conditions of the electric vehicle on different work conditions, so driving distance can be increased and emission can be reduced.

Description

Technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a distributed energy supply system for electric vehicles and a working method thereof. Background technique [0002] At present, the mainstream driving vehicles on the market that use new energy supplies mainly use pure power batteries to provide energy and hybrid energy-driven vehicles that use a single engine and a single power battery to provide energy supply. These technologies are used for different types of passenger cars and commercial vehicles. , The use of different driving conditions in urban and high-speed conditions have different limitations. Pure electric vehicles have zero emissions, but due to the constraints of battery technology, the driving range of the vehicle is very limited. Although the driving range of hybrid vehicles is guaranteed, the effect of energy saving and emission reduction is not obvious. Summary of the invention [0003] The purpose of the ...
