Power accounts for the ratio of power system load by increasing, will bring very important impact to security of system stable operation.Greatly
Most electric automobile car owners can have vehicle-mounted battery charger, and they are always happy to carry out in the garage of private savings charging,
Control and the management of business is not integrated by EV.Terminating to go back home when EV car owner drives a vehicle one day, first thing puts car into garage exactly,
Plug the charging electric vehicle for " hungry " for the power supply of charger, the now peak load period of often power system just, increase
Big peak-valley difference, brings burden to peak load regulation network.In addition, after " tou power price " is implemented, paddy electricity period (generally at night)
Electricity price is relatively low, selects paddy period charging (power purchase), utilizes this policy superiority can reduce electric automobile use cost.
Content of the invention it is an object of the invention to provide charger when one selects paddy, to solve prior art electric motor car charging
The problem existing, and realize being charged in the electric-net valley period.
In order to achieve the above object, the technical solution adopted in the present invention is:
Charger when selecting paddy, it is characterised in that: being switched on power mechanism by time delay and common charger being constituted, electricity is connected in described time delay
Source mechanism includes the control loop of contactor KM and contactor KM, and wherein contactor KM accesses 220V AC power to common charging
In the power line of machine charging, control loop is made up of three branch circuit parallel connections, and wherein Article 1 is propped up the centre that is sequentially connected in series of route and continued
The normally opened auxiliary of electrical equipment KA, start button SB1, stop button SB2 and the auxiliary reclay KA in parallel with start button SB1 connects
Point KA1 is constituted, and the time relay KT that Article 2 props up route on-delay is constituted, and Article 3 props up the contactor that route is sequentially connected in series
The control coil KM1 of KM, the normally opened on-delay auxiliary contact KT1 of time relay KT are constituted, after three branch roads are parallel with one another
Bypass again accesses in the power line between contactor KM and 220V AC power, and Article 1 branch road is with Article 2 branch road indirectly
Enter to have the normally opened auxiliary contact KA2 of auxiliary reclay KA.
Described charger when selecting paddy, it is characterised in that: time relay adjustable extent is more than 7 hours.
Described charger when selecting paddy, it is characterised in that: contactor KM rated operational current Ie should be general be connected
Logical charger coupling.
The beneficial effects of the present invention is:
A, due to the charger of a large amount of high-power power consumptions be have selected paddy electricity the period charging, stagger a day power load peak period,
Reduce peak-valley difference, decrease peak regulation amount, the beneficially safe and stable operation of power system.
B, thermal power plant are that peak-load regulating needs to waste substantial amounts of fuel, so reducing peak load regulation network amount i.e. decrease wave
Take and pollute, making the electric automobile of environmental protection add again a environmental protection contribution.
C, selection paddy period charging (power purchase), utilize " tou power price " policy superiority can reduce electric automobile use cost,
Bring economic benefit for EV car owner.
Brief description
Charger structural representation when Fig. 1 present invention selects paddy.
Fig. 2 power system " daily load curve " schematic diagram.
Detailed description of the invention
As it is shown in figure 1, charger when selecting paddy, being switched on power mechanism 1 by time delay and common charger 2 being constituted, time delay is connected
Power sector includes the control loop of contactor KM and contactor KM, and wherein contactor KM accesses 220V AC power to commonly filling
In the power line of motor charging, control loop is made up of three branch circuit parallel connections, and wherein Article 1 props up the centre that route is sequentially connected in series
The normally opened auxiliary of relay K A, start button SB1, stop button SB2 and the auxiliary reclay KA in parallel with start button SB1
Contact KA1 is constituted, and the time relay KT that Article 2 props up route on-delay is constituted, and Article 3 props up the contact that route is sequentially connected in series
The control coil KM1 of device KM, the normally opened on-delay auxiliary contact KT1 of time relay KT are constituted, and three branch roads are parallel with one another
After again bypass access in the power line between contactor KM and 220V AC power, and between Article 1 branch road and Article 2 branch road
Access the normally opened auxiliary contact KA2 having auxiliary reclay KA.
Time relay adjustable extent is more than 7 hours.Contactor KM rated operational current Ie should be common be connected
Charger mates.
Describe the problem with power system " daily load curve ", as shown in Figure 2.Shade part A in figure represents all and fills
The script load that motor does not adds, during its top load paragraph when the 20 of time coordinate axle on, the lowest trough period is close to 4
When.In figure；Shade part B represents all charger total loads.Owing to the charger of a large amount of high-power power consumptions be have selected paddy electricity
Period charges, and has been dragged to the load paddy period originally falling at the charging total load of script load peak period.As such, it is possible to solve
Certainly following three problem: the firstth, stagger a day power load peak period, reduces peak-valley difference, decreases peak regulation amount, is conducive to
The safe and stable operation of power system.Secondth, thermal power plant is that peak-load regulating needs to waste substantial amounts of fuel, so reducing electricity
Net peak regulation amount i.e. decreases waste and pollutes, and makes the electric automobile of environmental protection add again a environmental protection contribution.The 3rd, the select the paddy period
Charging (power purchase), utilizes this policy superiority can reduce electric automobile use cost, brings economic benefit for EV car owner.
The present invention is switched on power mechanism 1 by time delay and common charger 2 forms.Time delay switches on power mechanism 1 by contactor
KM and control loop composition thereof.Described control loop is made up of three parallel branches from left to right: Article 1 operates branch road, its
On have start button SB1, stop button SB2, normally opened auxiliary contact KA1, auxiliary reclay KA；Article 2 branch road has on-delay
Time relay KT；Article 3 branch road has normally opened on-delay auxiliary contact KT1, contactor control coil KM1.In addition, the
Article one, it between branch road and Article 2 branch road, is also provided with a normally opened auxiliary contact KA2.
2. scheme implementation process
When EV car owner parks when parking stall of charging is EV charging, first connect delay power mechanism 1 power supply, by time relay KT
Time delay setting value become the self-charging moment to paddy electricity period initial time when number (paddy electricity period initial time be commonly considered as
When 23).Then press lower start button SB1, auxiliary reclay KA coil electricity, make normally opened auxiliary contact KA1 close in self-sustaining
State (now start button SB1 is rebounded), also normally opened auxiliary contact KA2 is made to close.After KA2 Guan Bi, the time of on-delay continues
Electrical equipment KT coil electricity, time relay KT trigger, time delay always, to numerical value after action is previously set, makes normally opened energising prolong
When auxiliary contact KT1 adhesive, contactor KM control coil be energized, contactor KM main contact close, common charger 2 starts to fill
Electricity, now just paddy electricity period initial time.When EV car owner comes parking space again, off delay switches on power mechanism 1
Power supply, time delay switches on power mechanism 1 dead electricity, and contactor KM main contact cut-offs, and returns to normally open position, carries out standard for charging next time
Standby.
