One contact of the moving break contact and the moving close contact of the relay is connected in series with a charging line of the charging pile. The other charging line of the charging pile is connected to the parallel night plug and day plug. The other contact of the moving break contact of the relay is connected with the day-use pin. The other contact of the moving contact of the relay is connected with the night plug. When charging at night, the timer controls the relay to charge one car in the first 4 hours, and automatically switch to another car in the next 4 hours. The daytime timer doesn't work and the relay's moving contact can only charge one car.

Description

Automatic distributor for electric vehicle charging pile

technical field

The utility model relates to a control electric appliance, in particular to an automatic transfer switch matched with an electric vehicle charging pile, in particular to an automatic distributor of the electric vehicle charging pile.

Background technique

As of May 2017, my country has 1.004 million electric vehicles, 161,000 public charging piles, and 6 electric vehicles per pile. During the charging time of electric vehicles, it is best to use the low power consumption period from 11:00 at night to 7:00 am the next day. Taking the BYD K9 electric bus as an example, it takes 4 hours to charge each electric vehicle, and each charging pile can just charge two electric vehicles every night. The pile is equipped with an automatic distributor, which automatically switches at night to charge two electric vehicles.

Contents of the invention

The technical problem to be solved by the utility model is to realize the zero-time-slot switching of the successive charging of the front and rear cars by the car charging pile.

The technical solution adopted by the utility model is: the automatic distributor of the electric vehicle charging pile, including a timer and a relay; the control line of the timer is connected in series with the coil of the relay; The power line of the charging pile is connected to the power supply after being connected; one contact of the moving break contact and the moving closing contact of the relay is connected to a charging line of the charging pile after being connected, and the other charging line of the charging pile is respectively connected to the night plug and the daytime plug. The other contact of the moving-off contact of the relay is connected with the day-use plug; the other contact of the moving-closing contact of the relay is connected with the night-use plug.

When charging at night, 1. The night plug and the day plug are respectively connected to two electric vehicles. 2. Turn on the external power switch and timer switch, turn on the power, and the timer and charging pile will be powered on at the same time. 3. After the timer is energized, turn on the coil, attract the armature, drive the contact rod to close the moving contact, and disconnect the moving contact at the same time. At this time, one pole of the charging pile is passively connected to the night plug, because the other pole of the charging pile is directly connected to the night plug, and the night plug charges the connected car. 4. After the timer runs for 4 hours, the power will be automatically cut off, the coil will be de-energized, the armature will be released, the reset compression spring will pull the armature through the pull rod, and the armature will pull the contact rod to reset. At this time, one pole of the charging pile is passively disconnected and connected to the daytime plug, because the other pole of the charging pile is directly connected to the daytime plug, and the daytime plug charges the connected car. 5. The timer will automatically sound the time after 8 hours of electricity, indicating that the charging of the two vehicles is complete. The staff can cut off the timer switch to end the automatic charging of the two vehicles at night.

When charging during the day, only the external power switch is turned on, the timer switch is not turned on, the relay does not work, and one charging line of the charging pile is directly connected to the day-use plug; the other charging line passes through the movable contact of the relay and the day-use plug. Connected, the charging pile only charges the single vehicle alone, instead of charging the two vehicles successively with zero time slots.

The beneficial effects of the utility model are: the relay is controlled by the timer, the charging pile is controlled by the relay, and two electric vehicles are charged successively with zero time slot. Make full use of the low power consumption at night for 8 hours, the charging cost is low, the car will not be affected, and the comprehensive social benefits are good.

Detailed ways

The preferred way to realize the utility model is described in detail with reference to Fig. 1 as follows:

The automatic distributor of the electric vehicle charging pile includes a timer 1 and a relay 2. After the power line of the timer 1 is connected in parallel with the power line of the charging pile 3, it is connected to the 200V power supply through the double pole switch 4. The control line of timer 1 is connected in series with the coil 6 of relay 2. One contact of the moving break (normally closed) contact 7 and the moving close (normally open) contact 8 of the relay 2 is connected to a charging line of the charging pile 3 after being connected. Another charging line of the charging pile 3 is connected with the night plug 9 and the day plug 10 connected in parallel. Another contact of the movable contact 7 of the relay 2 links to each other with the daytime plug 10 . Another contact of the moving contact 8 of the relay 2 links to each other with the night use plug 9 .

The timer 1 has a time limit of 4 hours and 8 hours, a rated voltage of 200V, 50 Hz, a built-in switch 5, and a rated current equal to the rated current of the coil 6 of the relay 2.

The relay 2 adopts an electromagnetic current relay. There is a moving breaking contact 7 and a moving closing contact 8, and the rated current of both contacts is equal to the charging current of the charging pile 3.
