Technical field
This utility model belongs to automotive field, is specifically related to a kind of charging device for electric automobile.
Background technology
Charging device of the prior art for battery type vehicle is charged, have via chopper be connected to
The power line that the supply socket of device power supply (DPS) connects.But, it is not immediately that chopper is typically configured to when short circuit current flow
Tripping operation, but trip in the case of short circuit current flows continuously through the stipulated time more than.Therefore, if the not up to stipulated time,
Even if then short circuit current flow, chopper also will not trip, therefore, as long as from the moment of short circuit current flow through described
Charging current was reduced, it becomes possible to avoid the tripping operation of chopper before stipulated time.But, it is charged electric current at electric automobile
In the case of control, minimizing charging current is made to play reality at electric vehicle from being carried out instruction by charging device to electric vehicle
Till charging current is reduced in side, considerably long time delay can be produced.Further, this time delay is according to the kind of electric vehicle not
Different together, therefore the electric vehicle for all kinds adjusts charging current to avoid the tripping operation of chopper to be very difficult to.
Utility model content
For solving the problems referred to above, this utility model provides a kind of tripping operation general, that be avoided that chopper and will charge
Electric current is adjusted to the charging device of appropriate value.The technical solution of the utility model is as follows:
A kind of charging device for electric motor car, including:
The first automatic air-break switch being connected with power system, and many with being connected in parallel of the first automatic air-break switch
Individual second automatic air-break switch, the outlet side of the plurality of second automatic air-break switch connects electrical load；
Current measurement portion, control portion, communication unit, described current measurement portion uses the first current sensor, the second electric current to pass
The electric current of two electric wires of power system is flow through in sensor measurement, and each measured value is exported control portion.Control portion according to by
The current value of current measurement portion measurement and the magnitude of voltage of the input voltage of the first automatic air-break switch, calculate and supply from power system
The instantaneous value of electric power and aggregate-value.Communication unit conveys information to regulate unit by voltage signal, and described information is charged electrical
The higher limit information of stream.
Signal processing part, current transformer, detection of electrical leakage portion, break-make portion, adjustment unit, charge cable and plug.Break-make portion with
One of branch circuit of second automatic air-break switch branch connects, the charging that the 3rd current sensor measurement supplies to electric automobile
Electric current.Charge cable and plug plug are connected to be arranged in the charge port of electric automobile freely.
Charging device described in the utility model can independently avoid the tripping operation of chopper with the kind of electric vehicle, and
And charging current is adjusted to suitable value.
Accompanying drawing explanation
Fig. 1 is the system construction drawing of the charging device for electric motor car of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described, it is clear that described is only this reality
By novel a part of embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creation
Property work premise under the every other embodiment that obtained, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, described charging device includes:
The first automatic air-break switch 1 of being connected with power system, and with being connected in parallel of the first automatic air-break switch 1
Multiple second automatic air-break switches 2, the outlet side of the plurality of second automatic air-break switch 2 connects electrical load (not shown)；
Current measurement portion 3, control portion 4, communication unit 5, described current measurement portion 3 uses the first current sensor 11, second
The electric current of two electric wires flowing through power system measured by current sensor 12, and each measured value is exported control portion 4；
Control portion 4 is according to the current value measured by current measurement portion 3 and the electricity of the input voltage of the first automatic air-break switch 1
Pressure value, the instantaneous value of the electric power that calculating supplies from power system and aggregate-value；
Communication unit 5 conveys information to regulate unit 6 by voltage signal, and described information is the higher limit letter of charging current
Breath；
Process portion 7, current transformer 14, detection of electrical leakage portion 9, break-make portion 8, regulation unit 6, charge cable and plug 10；
One of branch circuit of break-make portion 8 and the second automatic air-break switch 2 branch is connected, the 3rd current sensor measurement 13
To the charging current of electric automobile supply, charge cable and plug 10 plug and are connected to be arranged at electric automobile freely and (do not show
Go out) charge port in.
Process portion 7, when signal level pilot signal being detected is reduced to predetermined value, makes break-make portion 8 Guan Bi start to fill
The supply of electricity electric power.
Control portion 4 is in the case of the electric current flowing through the first automatic air-break switch exceedes rated current so that from communication unit 5
Send the higher limit of charging current is set to from the current value of current charging current deduct wastage in bulk or weight electric current and rated current it
The instruction of the current value of difference gained, wastage in bulk or weight electric current is the summation consuming electric current of charging current and load equipment.Control portion 4 exists
Wastage in bulk or weight electric current is less than in the case of rated current, additionally it is possible to make to be sent in wastage in bulk or weight electric current less than specified from communication unit 5
The instruction of the higher limit of charging current is improved in the limit of electric current.
Charging device supplies electric current according to the higher limit of the electric current after adjusting to electric automobile.
Above-described detailed description of the invention, is entered the purpose of this utility model, technical scheme and beneficial effect
One step describes in detail, be it should be understood that and the foregoing is only detailed description of the invention of the present utility model, is not used to limit
