Example Embodiment

[0023] figure 1 It is a block diagram showing an electric vehicle intelligent charging system according to the present invention. The electric vehicle intelligent charging system includes: an AC / DC converter 2 connected to the distribution network 1 for converting the AC power of the distribution network 1 into DC power. The AC / DC converter 2 includes a current conversion module and a PWM pulse width modulation module. The current conversion module rectifies and converts the input 220V mains power to obtain a certain charging current. The PWM pulse width modulation module controls Signal to control the output of the AC / DC converter 2; the harmonic detection module 4 is used to detect the harmonics injected into the distribution network by the charging system in real time; the filter module 4 is used to eliminate the harmonics injected into the distribution network 1 from the charging system in real time Wave; multiple charging modules 5, used to charge multiple battery packs of ...

Abstract

The invention relates to a charging method based on an intelligent electric automobile charging system. By means of the method, the state of a single lithium ion battery of an electric automobile battery pack is detected in the charging process, balanced and self-adaptive charging is carried out according to the state of the battery and the state of a power distribution network, and the service life of the battery is prolonged. The system is further provided with a filter, and therefore harmonic waves injected into the power distribution network in the charging process can be reduced.

Description

technical field [0001] The invention relates to an intelligent charging method for an electric vehicle. Background technique [0002] Electric vehicles can reduce human's dependence on oil resources. With the depletion of global oil resources, electric vehicles are favored compared with traditional fuel vehicles. After the large-scale application of electric vehicles, it will bring new challenges to the development of charging facilities and the operation of the power grid: new load growth will be triggered; the existence of nonlinear components such as rectifiers in chargers will cause a large amount of power harmonic pollution, resulting in power The quality is deteriorating day by day, increasing the difficulty of distribution network operation and management. [0003] Under the background of smart grid, intelligent management of electric vehicle charging can avoid the adverse impact of electric vehicle charging demand on the grid and improve the operation efficiency of ...
