This utility model provides the charging system of a kind of new-energy automobile, by an AC-DC mould concentrated
The output of block provides power as dc bus for DC-DC charging module, and is rationally divided by master controller
Join the charge power of each DC-DC charging module；So, by the way of DC bus powered, solve
The charging caused for compatible high-power charging in existing independent distributed AC-DC charger scheme
Machine utilization rate is low, cost high problem.Further, charging system of the present utility model, owing to passing through dc bus
Centrally connected power supply, and the described DC-DC charging module volume that electric automobile is directly connected to is little, low cost, can
It is placed on suitable place the most flexibly, along with charge requirement change after Development of Electric Vehicles, updates
The cost of DC-DC charging module is the lowest, is adapted to the present situation that new-energy automobile is fast-developing.
The charging system of prior art is for the charge requirement of compatible different capacity, and the maximum of each charger is defeated
Go out power often much larger than the mean power of charging every time, and the most all chargers are great Rong the most simultaneously
The probability of amount battery car charging is the least, even if charge for large volume automobile simultaneously simultaneously, it is also difficult to
Simultaneously all in peak power charged state, thus cause the actual normal service rating of charger and be far below
Charger power sum, utilization rate is the lowest.And the charging system of the application, all of charger shares one
Concentrate AC-DC module, concentrate the charging merit that the power of AC-DC module normally can use according to reality
Rate configures, and is powered for multiple DC-DC charging modules 200 by dc bus 400, and passes through master control

Owing to this charging system is that same AC-DC module 100 is powered, therefore, it is to avoid prior art is filled
The low cost waste caused of charger utilization rate in power station, and DC-DC charging module can be that low cost is little
The non-isolated module of volume.
Meanwhile, existing charger is that independent AC-DC module is constituted, as shown in Figure 1.Each charging
Machine all arranges sufficiently bulky, occupies suitable space in the charging parking position of electric automobile.And the application provides
Charging system in, as the AC-DC module 100 of high-power power supply, with multiple DC-DC charging modules
200 can be separately positioned on different spaces, and therefore, described AC-DC module 100 can need not necessarily need to be provided
The charging place of electric automobile, but can be arranged on farther out or remote region, and only very small volume
DC-DC charging module is placed near parking stall, so substantially reduces the occupation of land on electric automobile parking stall
Area.
Optionally, described AC-DC module 100 is independently with described DC-DC charging module 200
Module.

200 are arranged on different spaces, in order to the space Appropriate application in charging electric vehicle place.
Optionally, multiple described DC-DC charging modules 200, for module independently.
Owing to each DC-DC charging module connects respectively at different electric automobiles, for different electronic vapour
Car charges, therefore, when each described DC-DC charging module 200 independently encapsulates, and its cost
Low volume is little, reduces the charger floor space in charging parking position further..
Optionally, the peak power output sum of all described DC-DC charging modules 200 is more than described
The output of AC-DC module 100.
Probability in view of all DC-DC charging modules 200 Maximum Power Output simultaneously is the most small, with
Time, all DC-DC charging modules 200 Maximum Power Output instantaneous power demands mistake to power distribution network simultaneously
Height, therefore, when designing the peak power output of AC-DC module 100, can be less than all DC-DC
The peak power sum of charging module 200 output.Such as, totally 10 DC-DC charging modules, each
The peak power output of DC-DC charging module is 50kw, and the maximum of described AC-DC module 100 is defeated
Go out power and can be less than 500kw.This is because all DC-DC charging modules are required to export 50kw simultaneously
Probability the lowest, therefore, described AC-DC module 100 also without being designed as the module of 500kw, this
Sample, the charging system of the application, can effectively reduce cost and the volume of AC-DC module 100, moreover it is possible to hold concurrently
Hold the charge power of different electric automobile.DC-DC charging module overall power requirement for accidentally occurring is big
In the situation of AC-DC module peak power output, master controller can be according to default algorithm distribution and limit
The power of DC-DC charging module processed, such as according to automobile dump energy number or charging price height low-key
Whole charging priority level.
It should be noted that the described charge requirement signal mentioned in the application, the most each
The DC-DC charging module same time all sends this signal, when corresponding DC-DC charging module connects electronic
During automobile, described DC-DC charging module can send charge requirement signal to master controller, and does not connects
The DC-DC charging module connecing electric automobile can not send charge requirement signal.
