Abstract

The invention relates to an intelligent charging device for electric vehicles. The intelligent charging device comprises an AC power grid interface module, and is characterized in that: the output end of the AC power grid interface module is connected with the input end of an AC-DC rectification module; the output end of the AC-DC rectification module is connected to the input end of a DC-AC high frequency isolation module; the output end of the DC-AC high frequency isolation module is connected to the input end of an AC-DC output module; and the output end of the AC-DC output module is connected with a charging interface module. The intelligent charging device for the electric vehicles improves conversion efficiency by adopting a zero-current switching (ZCS) technology, simultaneously reduces harmonic pollutions to a power grid and increases a power factor by adopting a pulse width modulation (PWM) rectification technology, and has two-way energy flow and control capability to reduce the wasting of electric energy.

Description

technical field

[0001] The invention relates to a charging device, in particular to an electric vehicle intelligent charging device. Background technique

[0002] At present, the on-board charging system for electric vehicles in China (including the F3E electric vehicle already on the market by BYD) is still an ordinary charging system. This is an important reason for the low market penetration rate of electric vehicles.

[0003] The large-scale fast charging stations currently planned to be built in China are similar to the refueling piles in gas stations. Theoretically, 70% to 80% of the electricity can be charged in a few minutes by using the fast charging method, but its essence is extensive constant voltage and high current power supply. It will cause damage to the life of the battery pack or even directly damage the battery pack. Contents of the invention

[0004] The object of the present invention is to provide an electric vehicle intelligent charging device in o...
