Description
Technical field
The present invention relates to a kind of many power section parallel connection quick charging system and method.
Background technology
In recent years, along with electric automobile (Electric Vehicle) and plug-in hybrid-power automobile (Plug-in
Hybrid Electric Vehicle) development of technology, electric automobile becomes the weight of people's trip by gradually replacing orthodox car
Want the vehicles.The charging technique of electric automobile has obtained proposing in increasing concern, academia and industrial quarters multiple
Effective charging structure and charging modes.According to charging device location, vehicle-mounted charging device (On-can be divided into
Board) and off-board charging device (Off-board), wherein vehicle-mounted charging device can be divided into again have call wire charging device and
Charging device without call wire.Divide according to existing power grade, 1 grade, 2 grades, 3 grades can be divided into.1 grade of charging device charge power
Minimum, about 1 ~ 2kW, this charging device mostly is vehicular, and volume is little, can utilize family, the common alternating current on office ground at any time
Charging in source, the charging interval was longer, more than 10 hours.2 grades of charging device power are about 4 ~ 20kW, mostly are vehicle-mounted charging device, can
Utilization meets the single-phase of power requirement or three-phase alternating-current supply is charged, and the charging interval is about 2 ~ 6 hours.3 grades of charging devices
Power is about 50 ~ 100kW, and charging device volume is relatively big, mostly is non-vehicle-mounted type, is generally used in special charging station, the charging interval
The shortest, about 0.2 ~ 1 hour, be the main development direction of following public charging device.3 grades of direct-current charging posts mostly are exchange-straight
Stream power electronic equipment, volume is relatively big, and equipment cost is high.
One DC charging station there may be multiple charging pile, owing to the charging interval of automobile is different, in some moment,
May only have minority charging pile in work, unnecessary charging pile cannot play a role, it is contemplated that charging pile price is higher, charging pile
Idle will reduce the income of charging station.As it is shown in figure 1, in the case of existing, when electric automobile quantity is less than charging pile quantity, often
Platform electric automobile still has a charging pile to power, and the charging interval is the longest, have impact on people's experience to electric motor car.And
Along with the development of electric motor car, not only there will be increasing electrocar, there is also other forms substantial amounts of electronic
Car, such as Electric Transit, motor wagon etc., different types of electric automobile has different charge power requirements, and power is little
Charging pile cannot meet the demand of large power, electrically electrical automobile, although high-power charging pile disclosure satisfy that wanting of all electric motor cars
Ask, but the cost of charging pile can be increased.Therefore it is badly in need of one to meet multiple charge power requirement, will not dramatically increase and build again
It is set as this charging technique.
Summary of the invention
For solving this problem, this patent proposes a kind of many power section parallel connection quick charging system and method.In existing charging
On the basis of device, increase power electronic equipment a small amount of, simple, make charging pile DC side power flexible between multiple charging piles
Exchange.When single charging pile can meet charge power requirement, single charging pile power.When single charging pile is unable to reach
When charge power requires, charging station control centre is according to the idle situation of existing charging pile, the also alliance of reasonable arrangement charging pile
Electrically, reach to meet the purpose of charge power requirement.This charging technique can arrange for different charge power demands
Different charging pile charged in parallel modes, the user both the met demand to quick charge, whole power station can be utilized again as far as possible
Charging ability, increase charging station operation income.
To achieve these goals, the present invention adopts the following technical scheme that
