Description
Technical field
The utility model relates to charging equipment of electric automobile fields, have power flexible distribution more particularly, to one kind
The charging device of electric automobile of function.
Background technique
With the fast development of pure electric automobile industry, new-energy automobile is current strategic new industry, and therewith
Matched electrically-charging equipment is the key that new-energy automobile industry development.Under the promotion energetically of country, from 2015, publication was simultaneously
Carry out the national standard for charging equipment --- " GB/T 18487.1-2015 electric car conduction charging system part 1
General Requirement ", " GB/T 20234.2-2015 electric car conduction chargeable connection device part 2: alternating-current charging interface ",
" GB/T 20234.3-2015 electric car conduction chargeable connection device third portion: direct-current charging interface ", " GB/T
Communication protocol between the off-board conduction-type charger of 27930-2015 electric car and battery management system ".In each standard
Stringent guide under, the interaction of charging equipment and electric car has clear, careful communication protocol, and outfit standard is inserted
Head.Various types of electric cars, as long as meet requirements of the national standard, there is standardized charging interface, it can be in office
It charges under He Yitai charging equipment.
Nevertheless, the rate of charge of batteries of electric automobile is not high for a long time, the charging time is too long, charging pile/charging
Ratio too low status in parking stall leverages general citizen for the confidence of purchase new-energy automobile.For above situation, fill
If power station operator faces awkward condition --- charging pile/charging parking stall ratio is improved, charge power is bigger fills for configuration
Electric equipment can preferably service electronic car owner certainly.But following problems will be brought:

But the power of charging equipment is bigger, and the volume of equipment is also bigger.Excessive equipment is not appropriate for being mounted on charging vehicle
Position side.Therefore, charging equipment is divided into 2 portions by the concept for having also been proposed split type charging equipment in the industry from structure
Point --- direct current output part is defined as seperated stake, and alternating current-direct current power conversion part is defined as power cabinet.Each producer is different
Hardware plan, by functions of the equipments be divided into power cabinet in seperated stake.Similar, a multiple gun can also be used in seperated stake
Form, it is common for 12 rifle.
Either monomer-type or split type charging equipment, when there are multiple gun form, Ying Yaoqiu device controller energy
Enough foundation actual conditions reasonable distribution charge powers are simply shared equally (i.e. every the specified of charging gun to each charging gun
Power invariability is constant) or wheel fill that (any moment only has a charging gun to charge, and starts next after a vehicle charging complete
Vehicle), so that each electric vehicle be made to quickly complete benefit electricity.And if the realization mechanism of power distribution is less reliable, function division
Interface is not reasonable, then the maintenance cost in equipment later period is high.
As it can be seen that one is executed reasonable power dispatch logic, is realized charge power dynamic allocation, function knot with reliable form
Structure divides reasonable charging equipment (charging system in other words), for charging station operator, new energy vehicle car owner, suffers from greatly
Benefit, it is also very necessary.
