Description
Technical Field
[0001] The utility model belongs to the field of charging equipment for new energy vehicles, and particularly relates to a charging pile with zero no-load power consumption. Background Technique
[0002] The simple schematic diagram of the existing charging pile switch control principle is as Figure 1 shown. The auxiliary power supply and control module in the circuit board are connected to the power grid through the power grid wiring component. This module is always in the working state to monitor the signal of the signal line of the charging gun. When the signal that the gun is plugged into the vehicle socket and can be charged is detected, the auxiliary power supply and control module recognize that the signal line of the gun line is conducted, and then control the power relay to close, thereby realizing the conduction of the power grid power line and the gun line and realizing charging.
[0003] In order to ensure plug-and-play inside the existing charging pile, the auxiliary power supply and control module inside the charging pile need to be always in the signal monitoring state, so no-load power consumption occurs when the charging pile is not in use, resulting in waste of electricity. Content of the Utility Model
[0004] The purpose of the utility model is to provide a charging pile with zero no-load power consumption, which can achieve zero no-load power consumption of the charging pile to reduce the waste of electricity when the charging pile is not in use.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a charging pile with zero no-load power consumption, including a charging pile main body and a charging gun. An empty socket for fixing the charging gun in a non-charging state is arranged on the charging pile main body. An auxiliary power supply and control module is arranged on the circuit board inside the charging pile main body. A control switch is arranged at the bottom of the empty socket. The button of the control switch is located inside the empty socket. The control switch is connected in series to the internal circuit of the auxiliary power supply and control module through a switch wire.
[0006] The beneficial effect is that when the charging pile is not used for charging, the charging gun is inserted into the empty socket and the button of the control switch is pressed to disconnect the control switch. Since the control switch is connected in series to the internal circuit of the auxiliary power supply and control module, the internal circuit of the auxiliary power supply and control module is in the off state and cannot consume the power monitoring signal, realizing zero no-load power consumption of the charging pile and saving electricity. When unplugging the gun for charging, the control switch can be automatically or manually closed to realize the conduction of the internal circuit of the auxiliary power supply and control module, so that the auxiliary power supply and control module can enter the signal monitoring state.
[0007] The control switch is a normally closed switch with an automatic closing function.
[0008] Its beneficial effects are as follows: A form of control switch is proposed. When the normally closed switch is not interfered externally, it is in the closed state. Therefore, when the charging gun is unplugged, the control switch automatically closes. After the charging gun is inserted into the empty socket, the front end of the charging gun can press the button of the control switch to disconnect the switch. The setting of the normally closed switch can make the charging operation more convenient and reliable.
[0009] The control switch is a manual switch.
[0010] Its beneficial effects are as follows: Another form of control switch is proposed. The switching of the switch state of the manual switch requires external force triggering. After using the manual switch, when the charging gun is unplugged, the user can press the manual switch to close it; when the charging gun is inserted into the empty socket, the front end of the charging gun can simulate the action of a human hand to press the manual switch to disconnect the switch. The setting of the manual switch can expand the applicable range of the present utility model, and the user can select a suitable switch according to the actual situation.
[0011] The circuit board is also provided with a grid wiring component. The auxiliary power supply and control module are connected to the grid through the grid wiring component; a gun line wiring component is used to connect the charging gun line and lead out the gun line signal line and gun line power line. The gun line signal line is connected to the auxiliary power supply and control module through the first path of the circuit board, and the gun line power line is connected to one end of the power relay on the circuit board through the second path of the circuit board. The other end of the power relay is connected to the grid wiring component.
[0012] The charging pile main body is an AC charging pile.
[0013] The beneficial effects of the present utility model are as follows: The present utility model controls the closing and opening of the control switch at the bottom of the empty socket by removing and inserting the charging gun from the charging pile, thereby controlling the power on and off of the auxiliary power supply and control module in the charging pile, realizing the on and off of the internal circuit of the charging pile, so that the internal circuit of the charging pile is in a disconnected zero-power consumption state when the charging gun is not in use, and eliminating the waste of electricity caused by the no-load power consumption of the charging pile.
[0014] The charging pile of the present utility model can be used as a home charging pile or a commercial charging pile, and both can reduce the use cost of the charging pile. When the present utility model is used for commercial charging piles, since the number of commercial charging piles is huge, the saving of electricity is particularly obvious, which conforms to the current development direction of energy conservation.

Specific implementation mode
[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for any limitation of the utility model.
[0019] Refer to the attached Figure 2 As shown, a charging pile with zero no-load power consumption includes a charging pile main body 1 and a charging gun 8. The charging pile main body 1 is an AC pile main body. An auxiliary power supply and control module 3, a grid connection component 4, a power relay 5, and a gun line connection component 6 are arranged on the circuit board 2 of the charging pile main body 1. The auxiliary power supply and control module 3 is connected to the power grid 10 through the grid connection component 4. The charging gun line 11 of the charging gun 8 is connected to the gun line connection component 6. The gun line signal line in the charging gun line 11 is led out from the gun line connection component 6 and then connected to the auxiliary power supply and control module 3 through the first connection path 7 on the circuit board 2. The gun line power line in the charging gun line 11 is led out from the gun line connection component 6 and then connected to one end of the power relay 5 through the second connection path 12 on the circuit board 2. The other end of the power relay 5 is connected to the grid connection component 4. An empty socket 9 is arranged on the charging pile main body 1 for fixing the charging gun. A control switch 13 is arranged at the bottom of the empty socket 9. The control switch 13 is connected in series to the circuit inside the auxiliary power supply and control module 3 through a switch wire 14. The button of the control switch 13 is located inside the empty socket 9, so that the button of the control switch 13 can be triggered after the charging gun 8 is inserted into the empty socket 9.
[0020] In the uncharged state of the charging pile, the charging gun 8 is inserted into the empty socket 9, and the front end of the charging gun 8 pushes the button of the control switch 13, so that the control switch 13 is disconnected, and then the circuit inside the auxiliary power supply and control module 3 is disconnected. At this time, the entire internal circuit of the charging pile is in a disconnected state with zero power consumption.
[0021] When charging is required, the charging gun 8 on the empty socket 9 is unplugged, the control switch 13 is closed, and the circuit inside the auxiliary power supply and control module 3 is conducted. The auxiliary power supply and control module 3 can monitor the gun line signal line 7. When it is detected that the charging gun 8 is plugged into the vehicle and charging is possible, the power relay 5 is controlled to close to charge the vehicle.
[0022] Preferably, the control switch 13 is a normally closed switch. After the charging gun 8 is unplugged, the normally closed switch automatically closes. After the charging gun 8 is inserted into the empty socket 9, the front end of the charging gun 8 presses the button of the normally closed switch, causing the normally closed switch to open.
[0023] In the above embodiments, the normally closed switch has the function of automatic closing, which can simplify the charging operation of the charging pile.
[0024] In other embodiments, if the automatic closing of the control switch is not required, a manual switch can also be used. When the charging gun 8 is unplugged, the button of the manual switch can be manually pressed to close the manual switch, and the circuit in the auxiliary power supply and control module 3 is turned on; when the charging gun 8 is inserted into the empty socket 9, the front end of the charging gun 8 can simulate a manual action to press the button of the manual switch, causing the manual switch to open. At this time, the entire internal circuit of the charging pile is in a disconnected zero-power consumption state.
[0025] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Those of ordinary skill in the art should understand that the specific implementation manners of the present invention can be modified or equivalently replaced by referring to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of the claims pending for approval.
