[0067] The first end of the charging and discharging connection wire harness is adapted to be connected with the vehicle charging and discharging connection end. In some embodiments, the vehicle charging and discharging connection end can be used for vehicle discharging or vehicle charging, wherein the vehicle charging and discharging connection end can be an integrated port of the vehicle charging end and the discharge end, or can include separate discharge ports or charging ports.

[0068] The second end of the charging and discharging connection wire harness is adapted to be connected with the power supply device, which can include but is not limited to charging piles, vehicles, power grids, etc.

[0069] The third end of the charging and discharging connection wire harness is connected with the discharging interface 120. The discharging interface 120 can be connected with the electrical equipment to supply power to the electrical equipment, that is, in some embodiments, the discharging interface 120 can function as a charging power strip, socket, etc.

[0070] The charging and discharging connection wire harness is used to transmit charging and discharging energy between any two of the connected vehicle, power supply device and discharging interface 120. For example, the charging and discharging connection wire harness is used to transmit charging and discharging energy between the connected vehicle and power supply device to realize charging and discharging of the vehicle, or the charging and discharging connection wire harness is used to transmit discharging energy between the connected vehicle and discharging interface to discharge through the discharging interface, or the charging and discharging connection wire harness is used to transmit discharging energy between the power supply device and discharging interface to discharge through the discharging interface.

[0071] Specifically, the charging and discharging connection device 100 of the embodiment of the present application integrates at least one discharging interface 120, which can be connected with the vehicle charging and discharging connection end and the power supply device through the charging and discharging connection wire harness to realize charging and discharging between any two connected ends, for example, charging and discharging energy between the vehicle and the power supply device can be transmitted through the charging and discharging connection wire harness, or charging and discharging energy between the vehicle and the discharging interface 120 can be transmitted through the charging and discharging connection wire harness, or charging and discharging energy between the discharging interface 120 and the power supply device can be transmitted through the charging and discharging connection wire harness.

[0072] In the embodiment, when the charging and discharging connection device 100 connects the vehicle charging and discharging connection end and the power supply device, when the vehicle needs to be charged, the power supply device can charge the vehicle through the charging and discharging connection wire harness, and at the same time that the power supply device charges the vehicle, the power supply device can also be controlled to supply power to the discharging interface 120, so that the discharging interface 120 can supply power to the connected electrical equipment; when the charging and discharging connection device 100 only connects the vehicle charging and discharging connection end, the vehicle battery can supply power to the discharging interface 120 through the vehicle charging and discharging connection end and the charging and discharging connection wire harness of the charging and discharging connection device 100, so that the discharging interface 120 can supply power to the connected electrical equipment; when the charging and discharging connection device 100 only connects the power supply device, the power supply device can supply power to the discharging interface 120 through the charging and discharging connection wire harness, so that the discharging interface 120 can supply power to the connected electrical equipment.

[0073] According to the charging and discharging connection device 100 of the embodiment of the present application, by integrating at least one discharging interface 120, the charging and discharging connection wire harness can be used to transmit charging and discharging energy between any two of the connected vehicle, power supply device and discharging interface, so as to realize the combination of charging and discharging circuits, integrate charging and discharging functions, share charging and discharging wire harness, effectively save costs, improve product utilization, and the circuit connection is simple, reliable, can meet the charging needs of users, can also meet the discharging needs, can also serve as a power strip discharging through the discharging interface, has a wide range of application scenarios, and improves the user experience.

[0074] In some embodiments, as shown in Figure 1 The charging and discharging connection device 100 further comprises at least one first switch 101, for example, the charging and discharging connection device 100 comprises one first switch 101 or comprises a plurality of first switches 101.

[0075] The first switch 101 is connected with the discharging interface 120 and the third end of the charging and discharging connection wire harness, and the first switch 101 is used to control the connection state between the connected discharging interface 120 and the charging and discharging connection wire harness.

[0076] Specifically, as shown in Figure 1 The first switch 101 is connected with at least one discharging interface 120, and the first switch 101 can also be connected with a plurality of discharging interfaces 120. The discharging interface 120 can be a two-hole discharging interface and a three-hole discharging interface, and a plurality of different discharging interfaces 120 can be set according to needs; the first switch 101 can be provided in plurality, and each first switch 101 is connected with a plurality of discharging interfaces, and a plurality of power consumption devices can be powered at the same time.

[0077] For example, considering that the user designs the charging and discharging connection device 100 to be compatible with the discharging function of the discharging interface 120 in different vehicle use conditions, the discharging interface 120 can be provided on a plugboard, the discharging interface 120 can be a jack provided on the plugboard, and the first switch 101 comprises a switch S4 and a switch S5. As in charging, the first switches S4 and S5 can be controlled to realize discharging of the discharging interface 120; as the charging and discharging connection device 100 serves as an off-board discharging gun, the first switch S5 can be controlled to realize discharging of the discharging interface 120, or the first switch S4 can be controlled to realize discharging of the discharging interface 120. The charging and discharging connection device 100 of the present application can have five working modes, for example, the charging and discharging connection device 100 is charged, the charging and discharging connection device 100 is off-board discharged, the charging and discharging connection device 100 is charged and the discharging interface 120 is discharged, the discharging interface 120 is discharged, and vehicle-to-vehicle power supply.

[0079] The at least one switch triggering unit 103 is connected with the at least one first switch 101 correspondingly, and the switch triggering unit 103 is configured to control the switch state of the connected first switch 101 based on a user operation instruction.

[0080] Specifically, as shown in the figure, Figure 1 The switch triggering unit 103 can be a button A or a button B. Since one switch triggering unit 103 is connected with one first switch 101 correspondingly, when the button B is pressed, the first switch S5 is closed,

[0081] and the discharge interface 120 is discharged. When the button A is pressed, the first switch S4 is closed, and the discharge interface 120 is discharged.

[0082] In some embodiments, as shown in the figure, Figure 1 The charge-discharge connection device 100 further comprises at least one prompting unit 102.

[0084] Specifically, the prompting unit 102 can be an indicator light. When the switch triggering unit 103 is triggered to close the corresponding first switch 101, the discharge interface 120 is discharged, and at this time, the indicator light arranged correspondingly with the switch triggering unit 103 is lit, indicating that the discharge interface 120 is working in discharge.

[0085] For example, when the charge-discharge connection device 100 is in the external discharge mode, the switches K1 and K2 in the control box are open, the switch S5 is closed to be conductive by the button B, the discharge interface 120 is discharged, and at this time Figure 2 the discharge indicator light D1 shown in the figure is lit.

[0089] In some embodiments, the discharging interface 120 includes at least one of a two-terminal jack, a three-terminal jack, and a USB interface.
