When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] Vehicle 10 is often used as a portable power source when there is no fixed power source, such as when users are camping outdoors or fishing by a river, requiring the power of the vehicle's battery device 20. The discharge device 40 can then electrically connect the battery device 20 to the electrical device. However, the discharge device 40 can only have one external socket, making it unusable when multiple electrical devices are connected.

[0027] This application discloses a discharge device 40, as shown in the attached document. Figure 1-4As shown, the discharge device 40 includes a DC gun 100, a control unit 210, a first DC socket 310, and a second DC socket 320.

[0028] The DC gun 100 is used to connect to the vehicle 10. The DC gun 100 is electrically connected to the control unit 210. The first DC connector 310 is electrically connected to the control unit 210 and is used to output electrical energy. The second DC connector 320 is electrically connected to the control unit 210 and is used to output electrical energy.

[0029] The control unit 210 is used to receive signals from the first DC connector 310 and control the switch of the second DC connector 320.

[0030] It should be noted that this embodiment only illustrates the first DC connector 310 and the second DC connector 320. In practice, other DC connectors may also be included, as long as two or more DC connectors are included within the scope of protection of this application.

[0031] Based on the above setup, the user has at least two DC sockets connected to the discharge device 40, giving the user more options for power outlets and thus a better user experience.

[0032] Furthermore, the first DC connector 310 and the second DC connector 320 share the same control unit 210, enabling the discharge device 40 to meet the needs of multiple sockets at a low cost. Also, since the control unit 210 receives the signal from the first DC connector 310 before controlling the switch of the second DC connector 320, it avoids the situation where the control unit 210 simultaneously receives signals from both the first DC connector 310 and the second DC connector 320, thus preventing identification failure. This design ensures the stability of the discharge device 40.

[0033] In one embodiment, reference Figure 3 As shown, the discharge device 40 includes a step-down converter 220, which is disposed between the DC gun 100 and the control unit 210 for reducing the voltage from the DC gun 100.

[0034] The aforementioned buck converter 220 is a DC / DC buck converter used to power core chips such as microcontrollers (MCUs). Core chips such as MCUs typically operate at lower voltages (e.g., 1.8V, 3.3V, 5V), while the main power supply voltage of the system is higher (e.g., 12V, 24V).

[0035] The buck converter 220 can efficiently reduce the higher input voltage to the stable operating voltage required by the control unit 210. The use of the buck converter 220 allows the control unit 210 to operate more stably.

[0036] Furthermore, when both the first DC connector 310 and the second DC connector 320 are operating, only one buck converter 220 is required. Therefore, cost savings can also be achieved by implementing multiple DC connectors.

[0037] In one embodiment, reference Figure 3 As shown, the discharge device 40 includes a relay device 400, which is disposed between the second DC socket 320 and the control unit 210, and is used to control the circuit connection of the second DC socket 320.

[0038] The aforementioned relay device 400 is an electrical control device and also an automatic switch. It uses a small current control signal to control the on / off state of a large current or high voltage circuit, realizing the function of controlling a strong current with a weak current and isolating the control circuit from the controlled circuit.

[0039] The control unit 210 can control whether the second DC connector 320 has current by controlling the opening and closing of the relay device 400. In this way, the current of the second DC connector 320 can be controlled so that it is not always in the open state, thus preventing risks such as short circuits.

[0040] In one embodiment, reference Figure 3 As shown, the relay device 400 includes a high-voltage relay 410 and a low-voltage relay 420. The second DC socket 320 includes a second high-voltage line 920 and a second low-voltage line 820. The second high-voltage line 920 is connected to the DC gun 100, and the second low-voltage line 820 is connected to the control unit 210.

[0041] A high-voltage relay 410 is installed on the second high-voltage line 920 to control the opening and closing of the second high-voltage line 920. A low-voltage relay 420 is installed on the second low-voltage line 820 to control the opening and closing of the second low-voltage line 820.

[0042] It should be noted that the main difference between the high-voltage relay 410 and the low-voltage relay 420 lies in the voltage levels that their contact terminals (controlled circuits) can withstand or control. The high-voltage relay 410 can operate in voltage ranges of 400V, 600V, 800V, and 1000V. It features stronger insulation, larger contact spacing, a special arc-extinguishing structure, and higher mechanical strength to ensure safe and reliable disconnection of large currents under high voltage, preventing arcing and personal injury accidents. The low-voltage relay 420 can operate in voltage ranges of 12V, 24V, 48V, 110V, and 400V. It has a relatively simple structure, smaller size, and lower cost, and is widely used in industrial control, home appliances, automobiles, and communication equipment.

[0043] The high-voltage relay 410 and the low-voltage relay 420 control the connection of the second high-voltage line 920 and the second low-voltage line 820, respectively, so that the second DC socket 320 can have either high voltage or low voltage. Furthermore, the presence of the high-voltage relay 410 and the low-voltage relay 420 prevents them from being constantly open, thus preventing risks such as short circuits.

[0044] In one embodiment, reference Figure 3 As shown, the discharge device 40 includes a first signal line 510 and a second signal line 520. The first signal line 510 is connected between the first DC socket 310 and the DC gun 100, and the second signal line 520 is connected between the second DC socket 320 and the control unit 210.

[0045] It should be noted that both the first signal line 510 and the second signal line 520 include a differential signal pair, namely, S+ and S-. This pair of lines transmits two signals of equal magnitude but opposite polarity. The receiving circuit detects the voltage difference (S+) - (S-) between these two signals.

[0046] The first DC connector 310 is directly connected to the DC gun 100 via the first signal line 510, and communicates with the vehicle through the DC gun 100. This ensures the smooth operation of the first DC connector 310. Furthermore, the second signal line 520 connects the second DC connector 320 and the control unit 210, enabling communication between them and allowing the control unit 210 to effectively control the second DC connector 320.

[0047] In one embodiment, reference Figure 3 As shown, the discharge device 40 includes a first channel line 610 and a second channel line 620. The first channel line 610 includes a first sub-line and a second sub-line. The first sub-line is connected between the first DC socket 310 and the DC gun 100, and the second sub-line is connected between the first DC socket 310 and the control unit 210. The second channel line 620 is connected between the second DC socket 320 and the control unit 210. The discharge device 40 includes a first grounding wire 710 and a second grounding wire 720, which are respectively grounded.

[0048] The first ground line 710 and the second ground line 720 are CC1 in the diagram. This is a crucial communication pin, primarily responsible for determining if a device is inserted. The first channel line 610 and the second channel line 620 are CC2 (Configuration Channel 2) in the diagram. The CC pin of the power supply end (Source, such as a charger) is connected to the power supply through a pull-up resistor (Rp). The CC pin of the power receiving end (Sink, such as a mobile phone) is connected to ground through a pull-down resistor (Rd).

[0049] Once the device is connected, the power supply side detects the voltage level on the CC2 pin to determine if a device has been inserted and to identify the type of device.

[0050] Based on the above configuration, the first DC connector 310 is not only connected to the DC gun 100, but also to the control unit 210, and is used to send signals to the control unit 210. The control unit 210 then determines whether to connect the high-voltage relay 410 and the low-voltage relay 420 based on the above signals, and then supplies power to the second DC connector 320.

[0051] In one embodiment, reference Figure 3 As shown, the discharge device 40 includes a first low-voltage line 810 and a second low-voltage line 820. The first low-voltage line 810 is connected between the first DC socket 310 and the DC gun 100, and the second low-voltage line 820 is connected between the second DC socket 320 and the control unit 210.

[0052] Both the first low-voltage line 810 and the second low-voltage line 820 mentioned above include a low-voltage positive power supply terminal (A+) and a low-voltage negative power supply terminal (A-). The low-voltage positive power supply terminal (A+) outputs the positive terminal of a low-voltage DC power supply. The voltage it provides is positive relative to the A- terminal, and this voltage value is relatively low (e.g., +3.3V, +2.5V, +1.8V). The low-voltage negative power supply terminal (A-) provides a current return path and is used in conjunction with A+ to provide a differential power supply.

[0053] The control unit 210 can further control the circuit connection of the second DC socket 320 by controlling the status of the second low-voltage line 820.

[0054] In one embodiment, reference Figure 3 As shown, the discharge device 40 includes a first high-voltage line 910 and a second high-voltage line 920. The first high-voltage line 910 is connected between the first DC socket 310 and the DC gun 100 and is used to energize the first DC socket 310. The second high-voltage line 920 is connected to the first high-voltage line 910 and is used to energize the second DC socket 320.

[0055] It should be noted that both the first high-voltage line 910 and the second high-voltage line 920 here include a DC positive terminal (DC+) and a DC negative terminal (DC-). That is, they include two polarity terminals for DC power.

[0056] The control unit 210 can control the connection of the circuit of the second DC socket 320 by controlling the status of the second high voltage line 920, thereby realizing whether the second DC socket 320 is energized or not.

[0057] In one embodiment, reference Figure 3As shown, the discharge device 40 includes a locking module 110, which is used to lock the DC gun 100 onto the vehicle 10 when the DC gun 100 is connected to the vehicle 10.

[0058] The locking module 110 can ensure that the discharge device 40 is locked on the vehicle, thereby avoiding problems such as the DC gun 100 being pulled off or poor contact when connected to the vehicle 10.

[0059] This application also proposes a vehicle comprising a battery device 20 as described in any of the above claims, a DC charging port 30, and a discharging device 40 as described in the above embodiments. The DC charging port 30 is connected to the battery device 20, and the DC gun 100 of the discharging device 40 is connected to the DC charging port 30.

[0060] The vehicle can be a car, truck, van, SUV, or any other type of vehicle equipped with a battery. In one embodiment, the vehicle is a high-voltage traction battery-powered electric vehicle (e.g., a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), etc.). In another embodiment, the vehicle is an autonomous vehicle, wherein the vehicle's maneuverability is controlled without direct input from a human driver.
