Description
Technical field
The present invention relates to electric vehicle rapid charging technical field, is specifically a kind of family expenses quick charge device and its control
Method.
Background technology
With the increase of environmental pressure, every country is all trying to explore utilization of new energy resources mode.Electric automobile is also near
Quick development is obtained within several years, electric energy ancillary equipment of the charging pile as electric automobile, is the key link that electric car is popularized.
China has become the most country of automobile charging pile at present.
Charging pile equipment is broadly divided into direct-current charging post (quick charge stake) and alternating-current charging pile (trickle charge stake), DC charging
Stake uses the form of direct current to charge for electric vehicle battery system, and direct-current charging post generally uses the three-phase four-wire system of 380v
(or phase three-wire three value) powers, and new charging pile is also bright in the universal standard in order to adapt to the requirement of DC power-supply system
Really represent to support DC power-supply system.Output voltage according to the charging requirement of charging object by controller on-line control, can be with
Provide two kinds of charging modes of quick charge and standard charging to the user.The alternating current for the 50Hz that alternating-current charging pile output is 220V,
Charge power supply is provided for electric car.Alternating-current charging pile is simple in structure, also smaller to net capacity requirement, using trickle charge mode
Charging.Direct-current charging post, in order to ensure the charging interval it is less, it is necessary to power grid provide power configuration it is higher, generally according to country.
According to the universal standard in China, the voltage class of DC charging equipment is divided into three classes：150V-350VDC、300V-500VDC、
450V-700VDC, can be divided into for different types of electric automobile, current class respectively：50A、80A、100A、150A、
The types such as 200A, 250A, 400A and 500A.The power bracket of these direct-current charging posts requirement is also relatively wider, from tens kilowatts
Differed to hundreds of kilowatts.By taking tesla's electric car as an example, tesla is charged using three kinds of modes at present：1st, filled using exchange
Electric stake mode, charges in the 110V power supplys of family, and the charger of greater efficiency can ensure garage within a hour
Sail 50 kilometers；2nd, can be doubled using the higher direct-current charging post of efficiency, charging rate, i.e., the charge volume of one hour can
To travel 100 kilometers or so；3rd, using efficient charging station, 480 kilometers can be travelled in a hour Rechargeable vehicle.Mesh
Before, mode 2 and mode 3 due to needing larger power in charging, general family due to the limitation for distribution system capacity of registering one's residence,
It is difficult to so big power access, so home-use charging modes are still in a manner of based on 1.This also just determines electronic
Car owner limits the use of electric automobile to a certain extent it is difficult to ensure that the charge volume being in.Also, in view of electric automobile
Fast development, it is following in living area and shopping centre of the population than comparatively dense, substantial amounts of charging equipment can all occur, while in order to suitable
Electric vehicle rapid charging and group is answered to fill the characteristics of group is put, this will bring great challenge to distribution system.
General family uses single phase power supply system, or three-phase power supply system, its distribution capacity to be generally 10kW or so, this
A capacity is typically to carry out technology with electric loading according to family's tradition, according to existing national standards《Design of civil buildings is advised
Model》Regulation, ordinary residence power load is 2.5kW, 4kW；Health residential area power load is：Basic model 4kW/ families, raising type
6kW/ families, advanced version 8kW/ families.For some larger residential electric power systems maximum capacity only in 50kW or so, for
Such register one's residence capacity and distribution system, it is difficult to install fast charge equipment.The three-phase that traditional fast-speed direct current charging pile uses
Electric power system or DC power-supply system, it is desirable to which distribution capacity is larger, generally more than 200kW, therefore in home-use distribution
Traditional quick charge stake can not be installed.
