A kind of quick charger used for electric vehicle, including quick charger, it is made up of 5 parallel branches, each branch road
All it is the charhing unit of an independent completion, single charhing unit peak power output is 10kw；Inside each charhing unit
Mains current passes through harmonic filter, power factor controller, current transformer, high frequency transformer, rectifier, line voltage is carried out
Rectification；It is transferred to finally by single multicore cable on charging plug.
Preferably, the converter is really ac-ac frequency converter, and the power frequency ac voltage from power supply is transformed into high frequency
High frequency transformer is inputted after alternating voltage, transformer is significantly reduced quality and diminution on the premise of transimission power is constant
Volume；Current transformer is connected by power factor controller (PFC) and harmonic filter with 200V power frequency supplies, is so not only made
The power-factor of load of power supply makes the total amount into power supply individual harmonic current be controlled in less than 3% close to 1；It is high
Frequency power transformer also achieves being effectively isolated between DC output end and power frequency AC in the colleague for carrying out voltage transformation, really
The peace of DC charging side is protected；High-frequency ac voltage is exchanged into 50-500V adjustable DC output voltages by rectifier.Direct current output
End connects through cable with charging plug, and the charging socket that charging plug is inserted in electric automobile can be implemented to fill to on-vehicle battery
Electricity.
Preferably, the charging plug and single multicore cable are internally provided with charging main circuit and transmit information
Control circuit.
Preferably, charging display frequency is provided with the quick charger, display screen is additionally provided with operation input keyboard.
The beneficial effects of the invention are as follows：
Charger of the present invention has the rectification function of standard, also and then conveniently charges, and control is provided with charging plug
Circuit processed, ensure information transfer, detect charge information in real time, display screen practical operation, meet demands of individuals.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is present invention quick charger schematic diagram used for electric vehicle.
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
As shown in figure 1, the present invention a kind of quick charger used for electric vehicle, including quick charger are disclosed, its by 5 simultaneously
Join branch road composition, each branch road is the charhing unit of an independent completion, and single charhing unit peak power output is 10kw；
Mains current inside each charhing unit passes through harmonic filter, power factor controller, current transformer, and high frequency transformer is whole
Device is flowed, rectification is carried out to line voltage；It is transferred to finally by single multicore cable on charging plug.Make for convenience of multiple users
With simultaneously the output block dispersed placement of five charhing units, these charhing units can be run, and can also stagger the time operation, whole
Number of the power output of quick charger depending on the charhing unit that puts into operation；When some charhing unit hinders and out of service for some reason
When, other normal charhing units may continue to run, charhing unit cloud with pulse width modulation (pwm) technology realize exchange-
Direct current exchanges.The converter is really ac-ac frequency converter, and the power frequency ac voltage from power supply is transformed into high-frequency alternating current
High frequency transformer is inputted after pressure, transformer is significantly reduced quality on the premise of transimission power is constant and reduces volume；
Current transformer is connected by power factor controller (PFC) and harmonic filter with 200V power frequency supplies, so not only makes power supply
The power-factor of load close to 1, and the total amount into power supply individual harmonic current is controlled in less than 3%；High frequency becomes
Depressor also achieves being effectively isolated between DC output end and power frequency AC in the colleague for carrying out voltage transformation, it is ensured that
The peace of DC charging side；High-frequency ac voltage is exchanged into 50-500V adjustable DC output voltages by rectifier.DC output end passes through
Cable connects with charging plug, and the charging socket that charging plug is inserted in electric automobile can be implemented to charge to on-vehicle battery.
The charging plug and single multicore cable are internally provided with charging main circuit and transmit the control electricity of information
Road, charging display frequency is provided with the quick charger, and display screen is additionally provided with operation input keyboard.First by quick charge
Device sends charging start signal, and control system receives the answer signal of electric automobile and confirms quick charger and electric automobile
Charging plug is locked all in instruction is sent after normal condition immediately, then started to charge up.In charging process, quick charge
Charging current magnitude signal that device is sent according to electric automobile and export corresponding charging current, what is sent by electric automobile
Charging is terminated after charging completion signal, charging process is fully automated by the whole display of display screen on panel, whole charging process
