Referring to fig. 1 to 4, a charge and discharge socket according to an embodiment of the present application is exemplarily described, and the charge and discharge socket 100 includes a first connection interface 110, a second connection interface 120, a selection switch 130, and an identification circuit 140. Fig. 1 shows a schematic structural diagram of a charge and discharge socket according to an embodiment of the present application, fig. 2 shows a schematic circuit diagram of a charge and discharge system according to an embodiment of the present application, fig. 3 shows a schematic circuit diagram of a charge and discharge system according to an embodiment of the present application, and fig. 4 shows a schematic structural diagram of a charge and discharge socket according to an embodiment of the present application. Illustratively, fig. 2 shows a schematic circuit diagram of the selector switch 130 in the first state, and fig. 3 shows a schematic circuit diagram of the selector switch 130 in the second state.

In one example, the selection switch 130 is operable by a user to be in a first state or a second state, as shown in fig. 1, the selection switch 130 including a "charge" gear and a "discharge" gear. In this embodiment, when the selector switch 130 is toggled to the "charge" gear, the selector switch 130 is in the first state; when the selector switch 130 is shifted to the "discharging" gear, the selector switch 130 is in the second state. In other embodiments, the selection switch 130 may be any other suitable switch type.

In one example, as shown in fig. 1 and 2, the first connection interface 110 includes a first live wire terminal 111 and a first ground wire terminal 112, the first live wire terminal 111 is connected to the first live wire 113, and the first ground wire terminal 112 is connected to the first ground wire 114. Illustratively, the first connection interface further includes a connection confirmation terminal 115 and a control guide terminal 116, wherein the connection confirmation terminal 115 is used for transmitting a connection confirmation signal, the vehicle control device is connected with the connection confirmation terminal through a connection confirmation line 117, and the vehicle control device can identify the connection condition of the first connection interface with an external alternating current charging gun or discharging gun by detecting the change of the voltage of the monitoring point on the connection confirmation line 117; the control pilot terminal 116 is used to learn the parameters of the vehicle-mounted battery and can output a duty cycle signal to regulate the ac charging current or the ac discharging current. Illustratively, as shown in fig. 1 and 2, the first connection interface 110 further includes a first neutral terminal 118, and the first neutral terminal 118 is connected to the in-vehicle power supply device 150 through a neutral wire. For example, as shown in fig. 1, when the external ac charging gun is charged by the three-phase ac power source through the first connection interface 110 or the external discharging gun needs to be discharged to the outside in the form of the three-phase ac power source through the first connection interface 110, the first connection interface may further include a second phase live wire terminal 1111 and a third phase live wire terminal 1112, and the first and second phase live wire terminals 111 and 1111 and the third phase live wire terminal 1112 output ac power with the same frequency, opposite amplitude and 120 degrees phase difference in sequence. For example, when single-phase alternating current is used to charge or discharge the electricity through the first connection interface 110, only the first live wire terminal 111 is required to be connected, and the second phase live wire terminal 1111 and the third phase live wire terminal 1112 are not required to be connected, and the input voltage or the output voltage is 220V; when three-phase alternating current is used for charging or discharging through the first connection interface 110, the input voltage or the output voltage is 380V. The first connection interface 110 is mainly used for charging the vehicle from the charging pile through the charging gun, and when the vehicle needs to be discharged outside through the first connection interface 110, the electric device cannot be directly connected with the first connection interface 110, and the first connection interface 110 and the electric device need to be respectively connected through the special discharging gun. Illustratively, the in-vehicle power supply 150 includes a bi-directional in-vehicle charger.

In one example, as shown in fig. 2, when the selector switch 130 is in the first state, i.e., the selector switch 130 is shifted to the "charge" position, the first power line 113 is connected to the power supply-side power line 151, the first ground line 114 is connected to the power supply-side ground line 152, the power supply-side power line 151 is in turn connected to the vehicle-mounted power supply 150, and the power supply-side ground line 152 is grounded, so that the first connection interface 110 is connected to the vehicle-mounted power supply 150. For example, when the selection switch 130 is in the first state, the ac charging gun can be connected to the first connection interface 110, and when the vehicle control device 170 recognizes that the ac charging gun is in the completely connected state with the first connection interface 110, the single-phase ac or three-phase ac can be introduced from the charging pile through the ac charging gun, and transmitted into the vehicle-mounted power supply device 150 through the first connection interface 110 to charge the vehicle-mounted power supply device 150, and the vehicle-mounted power supply device 150 can convert the single-phase ac or three-phase ac into dc and transmit to the vehicle-mounted battery 160 to complete the charging of the vehicle-mounted battery 160. For example, when the selection switch 130 is in the first state, a dedicated discharge gun can be connected to the first connection interface 110, and when the vehicle control device 170 recognizes that the discharge gun is in the fully connected state with the first connection interface 110, the vehicle control device 170 can control the in-vehicle power supply device 150 to convert the direct current in the in-vehicle battery 160 into the alternating current and discharge the electricity through the first connection interface 110.

In one example, as shown in fig. 1 and 3, the second connection interface 120 includes a second live wire terminal 121 and a second ground wire terminal 122, the second live wire terminal 121 being connected to the second live wire 123, the second ground wire terminal 122 being connected to the second ground wire 124. Illustratively, the second connection interface further includes a second neutral terminal 125, the second neutral terminal 125 being connected to the on-board power supply via a neutral.

In one example, as shown in fig. 3, when the selector switch 130 is in the second state, i.e., the selector switch 130 is shifted to the "discharge" gear, the second power line 123 is connected to the power supply-side power line 151, the second ground line 124 is connected to the power supply-side ground line 152, the power supply-side power line 151 is in turn connected to the vehicle-mounted power supply 150, and the power supply-side ground line 152 is grounded, so that the second connection interface 120 is connected to the vehicle-mounted power supply 150. For example, when the selection switch 130 is in the second state, the vehicle control device 170 needs to detect whether the second connection interface 120 is in a connection state with the plug of the electric device by receiving the first voltage signal or the second voltage signal output by the identification circuit, and when detecting that the second connection interface 120 is not connected with the plug of the electric device, the vehicle control device 170 will not control the vehicle power supply device 150 to provide the discharge voltage for the second connection interface 120, so that energy is saved, meanwhile, the occurrence of safety accidents caused by mistakenly touching the second connection interface is prevented, the potential safety hazard is eliminated, and the safety is improved; when it is detected that the second connection interface 120 is connected to the plug of the electric device, the vehicle control device 170 controls the in-vehicle power supply device 150 to supply the discharge voltage to the second connection interface 120. Illustratively, when the vehicle control device 170 receives the first voltage signal, the vehicle control device 170 controls the in-vehicle power supply device 150 not to supply the discharge voltage to the second connection interface 120; when the vehicle control device 170 receives the second voltage signal, the vehicle control device 170 controls the in-vehicle power supply device 150 to supply the discharge voltage to the second connection interface 120. For example, the vehicle control device 170 can convert direct current in the in-vehicle battery 160 into alternating current output. Illustratively, when discharging the electricity to the outside through the second connection interface 120, the second connection interface 120 can be directly connected with the plug of the electric equipment, without connecting the discharge gun with the second connection interface 120, and then connecting the discharge gun with the plug of the electric equipment, thereby greatly simplifying the charge-discharge conversion process, avoiding the use of the same interface for charging and discharging, reducing the cost and saving the space. For example, as shown in fig. 1, the second connection interface 120 may be a three-hole interface and/or a two-hole interface. Illustratively, when the second connection interface 120 is a two-hole interface, the second connection interface 120 includes only the second live wire terminal 121 and the second neutral wire terminal 125, and does not include the second ground wire terminal 122, and when the selection switch 130 is in the second state, the second live wire 123 is connected to the power supply device terminal live wire 151. For example, the discharge voltage may be a single-phase 220V ac voltage or a three-phase 380V ac voltage according to practical requirements and standards. Illustratively, the electric device may be an electric device such as a mobile phone, a charger. For example, fig. 3 shows a schematic circuit diagram of the selection switch 130 in the second state and the second connection interface 120 is in the connection state with the plug of the electric device, that is, the identification switch 141 in fig. 3 is in the closed state, and the identification switch 141 is in the open state when the second connection interface 120 is not in the connection state with the plug of the electric device.

In one example, as shown in fig. 2 or 3, the identification circuit 140 is connected to the second connection interface 120 and the vehicle control device 170, respectively, and specifically, the identification circuit 140 is connected to the second ground terminal 122 of the second connection interface 120 and to the vehicle control device 170 through the connection confirmation line 117.

In one example, as shown in fig. 2 or 3, the identification circuit 140 includes an identification switch 141, a first identification resistor 142, and a second identification resistor 143, wherein the identification switch 141 is connected in parallel with the first identification resistor 142, and the identification switch 141 is connected in series with the second identification resistor 143 in its entirety with the first identification resistor 142. Illustratively, as shown in fig. 1, the identification switch 141 is disposed in the area of the second connection interface 120, and the identification switch 141 is pressed when the plug of the electric device is connected to the second connection interface 120. The identification switch 141 is a normally open switch, when the second connection interface 120 is not connected to the plug of the electric device, the identification switch 141 is turned off, the first identification resistor 142 is connected in series with the second identification resistor 143, the total resistance of the identification circuit 140 is the sum of the resistance of the first identification resistor 142 and the resistance of the second identification resistor 143, and the identification circuit 140 outputs a voltage signal to the vehicle control device 170 as a first voltage signal; when the second connection interface 120 is connected with the plug of the electric device, the identification switch 141 is closed, the first identification resistor 142 is shorted by the identification switch 141, the resistance value of the identification resistor 140 is equal to the resistance value of the second identification resistor 143, and the identification circuit 140 outputs a voltage signal to the vehicle control device 170 as a second voltage signal. Illustratively, when the second connection interface 120 is not connected to the plug of the electric device, the total resistance of the identification circuit 140 is greater than the total resistance of the identification circuit 140 when the second connection interface 120 is connected to the plug of the electric device, so that the first voltage signal output by the identification circuit 140 is greater than the second voltage signal when the second connection interface 120 is not connected to the plug of the electric device. For example, the vehicle control device 170 may receive the voltage signal output by the identification circuit 140 and detect whether the plug of the electric device is connected to the second connection interface 120 by identifying the voltage signal as the first voltage signal or the second voltage signal. For example, suitable resistance values should be selected for the first identification resistor 142 and the second identification resistor 143 according to actual requirements. For example, as shown in fig. 1, the second connection interface 120 may be a three-hole interface and/or a two-hole interface, where the three-hole interface corresponds to a three-pin plug, the two-hole interface corresponds to a two-pin plug, and the identification switch 141 should be disposed at a position where the two-pin plug or the triangle plug in the area of the second connection interface 120 can be pressed when being inserted.

In one example, identification switch 141 is smaller than the insertion size of the plug of the powered device. Illustratively, the insertion size of the plug of the electrical device refers to the length of the pins of the plug entering the second connection interface 120 when the plug of the electrical device is fully connected with the second connection interface 120. Illustratively, when the identification switch 141 is smaller than the insertion size of the plug of the electric device, during the process of pulling out the plug of the electric device from the second connection interface 120, when the plug of the electric device is not completely pulled out from the second connection interface 120, the identification switch 141 is changed from the closed state to the open state, the vehicle control device 170 receives the second voltage signal output by the identification circuit 140, and controls the vehicle-mounted power supply device 150 to stop providing the discharge voltage to the second connection interface, thereby avoiding live plug-in and improving safety.

In one example, as shown in fig. 4, the charge and discharge socket 100 further includes a third connection interface 180, the third connection interface 180 is connected with the in-vehicle battery 160, and the third connection interface 180 is also capable of being connected with a direct current charging gun to charge the in-vehicle battery 160.

In one example, as shown in fig. 4, the third connection interface 180 includes a positive terminal 181 and a negative terminal 182, the positive terminal 181 being connected to the positive electrode of the in-vehicle battery 160, the negative terminal 182 being connected to the negative electrode of the in-vehicle battery 160. The third connection interface 180 further includes other terminals, such as a terminal for data communication, a terminal for confirming a connection state of the third connection interface 180 and the dc charging gun, a terminal for confirming a connection state of the dc charging gun and the charging post, a terminal for providing an auxiliary power supply, and a terminal for grounding, which are not described herein. For example, when the third connection interface 180 is connected to the dc charging gun to charge the vehicle-mounted battery 160, the vehicle control device 170 controls the vehicle-mounted power supply device 150 to stop working, i.e., the vehicle-mounted power supply device 150 neither charges the vehicle-mounted battery 160 nor discharges externally, i.e., at this time, it is impossible to charge or discharge externally through the first connection interface 110, or the second connection interface 120 discharges; when the vehicle control device 170 is in the process of charging or externally discharging the first connection interface 110 or in the process of discharging the second connection interface 120, the vehicle control device 170 controls the third connection interface 180 to stop working, that is, the vehicle-mounted battery 160 cannot be charged through the third connection interface 180 at this time.

In one example, a first protective cover is provided on the first connection interface 110, and/or a second protective cover is provided on the second connection interface 120, and/or a third protective cover is provided on the third connection interface 180. Illustratively, the first protective cover, the second protective cover and the third protective cover can prevent dust, rainwater and other substances from entering the interfaces when not in use, so as to keep the first connection interface 110, the second connection interface 120 and the third connection interface 180 clean, and eliminate potential safety hazards caused by foreign matters entering the interfaces.

The description of the structure of the charging and discharging socket of the present application is completed so far, and the complete charging and discharging socket may further include other components, which are not described in detail herein.

In summary, the charging and discharging socket according to the embodiment of the present application includes a first connection interface, a second connection interface, a selection switch and an identification circuit, where the first connection interface can connect an ac charging gun to charge or connect a discharging gun to discharge when the selection switch is in the first state, and the second connection interface can directly connect a plug of an electric device to discharge when the selection switch is in the second state, so that the connection of the discharging gun is not needed, and charging and discharging functions are independently implemented on the same socket, and the charging and discharging process is simplified, the cost is reduced, and the space is saved; the identification circuit comprises an identification switch, the identification switch is pressed when the plug of the electric equipment is connected with the second connection interface, so that a voltage signal output by the identification circuit is changed from a first voltage signal to a second voltage signal, and the vehicle control device can detect the connection state of the plug of the electric equipment and the second connection interface according to the received change of the voltage signal output by the identification circuit, thereby not providing discharge voltage for the second connection interface when the plug of the electric equipment and the second connection interface are not connected, saving energy and improving safety; in addition, the stroke of the identification switch is smaller than the insertion size of the plug of the electric equipment, so that the live plug is avoided; furthermore, the first protection cover is arranged on the first connection interface, the second protection cover is arranged on the second connection interface, and/or the third protection cover is arranged on the third connection interface, so that the cleanliness of the interface can be maintained, and foreign matters are prevented from entering the interface. The charging and discharging socket may further include a third connection interface for connecting the dc charging gun to charge the vehicle-mounted battery, and the vehicle control device may control the operation states of the first connection interface, the second connection interface, and the third connection interface to avoid interference with each other.

The embodiment of the present application further provides a charging and discharging system, as shown in fig. 2 or fig. 3, where the charging and discharging system 200 includes the charging and discharging socket 100, the vehicle-mounted power supply device 150, the vehicle-mounted battery 160, and the vehicle control device 170.

In one example, the in-vehicle power supply device 150 can convert the alternating current into the direct current to be input into the in-vehicle battery 160 to charge the in-vehicle battery 160, and the in-vehicle power supply device 150 can also convert the direct current in the in-vehicle battery 160 into the alternating current to be output to the outside.

In one example, the in-vehicle battery 160 is connected to the in-vehicle power supply device 150, and can be charged or discharged by the in-vehicle power supply device 150. For example, the direct current may be directly supplied to the in-vehicle battery 160 to charge the in-vehicle battery 160 without being converted by the in-vehicle power supply device 150.

In one example, the vehicle control device 170 can control the in-vehicle power supply device 150 to operate or stop operating according to the received voltage signal. For example, the vehicle control device 170 may be further configured to confirm the connection status of each interface and detect the related parameters of the circuit of the charge-discharge system, which is not described herein.
