[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] Reference below Figure 1 A vehicle charging device 100 and a vehicle having the same according to an embodiment of the present invention will be described.

[0031] like Figure 1As shown, the charging device 100 for a vehicle according to an embodiment of the present utility model includes: a first branch 1, a second branch 2, a third branch 3 and a fourth branch 4. The second branch 2 is selectively connected to the first branch 1 or the third branch 3, the fourth branch 4 is suitable for connecting to the vehicle controller, and the fourth branch 4 is selectively turned on or off. The second branch 2 can be connected to the first branch 1, and the fourth branch 4 can be in one of the turned-on or turned-off states, so that the charging device 100 switches to the single-pile dual-gun charging mode. The second branch 2 can be connected to the third branch 3, and the fourth branch 4 can be in the other of the turned-on or turned-off states, so that the charging device 100 switches to the dual-pile independent charging mode.

[0032] Among them, the vehicle charging device 100 is provided with a first branch 1, a second branch 2, a third branch 3 and a fourth branch 4. The second branch 2 can be selectively connected to the first branch 1 or the third branch 3 to form two working states. The two working states correspond to the single-pile dual-gun charging mode and the dual-pile independent charging mode, respectively. The first working state is that the first branch 1 and the second branch 2 are connected and the second branch 2 and the third branch 3 are disconnected. The second working state is that the first branch 1 and the second branch 2 are disconnected and the second branch 2 and the third branch 3 are connected, so that the working mode of the charging device 100 can be switched between the single-pile dual-gun charging mode and the dual-pile independent charging mode. In addition, the fourth branch 4 can be connected to the vehicle's controller, and the fourth branch 4 transmits a level signal to the controller. The fourth branch 4 can be selectively turned on or off. The turning on or off of the fourth branch 4 corresponds to the two working modes of the charging device 100. When the charging device 100 is in the first working state, the fourth branch 4 can be in one of the turned on or off states, and the charging device 100 corresponds to one of the working modes of the single-pile dual-gun charging mode or the dual-pile independent charging mode. When the charging device 100 is in the second working state, the fourth branch 4 can be in the other of the turned on or off states, and the charging device 100 corresponds to the other of the working modes of the single-pile dual-gun charging mode or the dual-pile independent charging mode.

[0033] As some embodiments of the present application, the controller can be constructed as a BMS (Battery Management System), or the controller can be integrated into a vehicle controller.

[0034] As some embodiments of the present application, the vehicle may include a first charging socket and a second charging socket, the first charging socket is connected to the first branch 1, the second charging socket is connected to the second branch 2, the controller is connected to the third branch 3, and the first charging socket is connected to the controller.

[0035] In the first operating state (single-pile dual-charger charging mode), the first branch 1 and the second branch 2 are connected, and the second branch 2 and the third branch 3 are disconnected, so that the first charging socket and the second charging socket are connected in parallel to form a charging communication circuit. In addition, the fourth branch 4 is disconnected, and the level signal transmitted by the fourth branch 4 to the controller is invalid. The controller recognizes the invalid level signal and can determine that the charging device 100 is in the single-pile dual-charger charging mode. In the second operating state (dual-pile independent charging mode), the first branch 1 and the second branch 2 are disconnected, and the second branch 2 and the third branch 3 are connected, so that the first charging socket and the second charging socket are independently connected to the controller to form two independent charging communication circuits. In addition, the fourth branch 4 is connected, and the fourth branch 4 transmits a valid level signal to the controller. The controller can use the valid level signal to determine that the charging device 100 is in the dual-pile independent charging mode.

[0036] In the above embodiment, by enabling the second branch 2 to be selectively connected to the first branch 1 or the third branch 3, and enabling the fourth branch 4 connected to the vehicle's controller to be selectively turned on or off, the charging device 100 can be switched between a single-pile dual-gun charging mode and a dual-pile independent charging mode, so that the vehicle can select different charging modes according to actual needs through the charging device 100, which can broaden the vehicle's charging scenarios and enhance the user's vehicle experience. In addition, the charging device 100 proposed in this application does not need to be used with two controllers, which can save costs.

[0037] In some embodiments of the present invention, Figure 1 As shown, the vehicle charging device 100 further includes: a first switch 5 and a second switch 6 . The first switch 5 is provided between the second branch 2 and the first branch 1 , and the second switch 6 is provided between the second branch 2 and the third branch 3 .

[0038] Among them, the first switch 5 can control the connection or disconnection of the first branch 1 and the second branch 2, and the second switch 6 can control the connection or disconnection of the first branch 1 and the third branch 3, so that the charging device 100 can switch between a single-pile dual-gun charging mode and a dual-pile independent charging mode. By controlling the two charging modes of the charging device 100 through the first switch 5 and the second switch 6, the difficulty of switching the charging mode can be reduced, and the instructions for switching the charging mode can be implemented simply and quickly, which can improve the user's car experience.

[0039] In some embodiments of the present invention, Figure 1 As shown, the first switch 5 and the second switch 6 are linked and in opposite states, so that the second branch 2 is selectively connected to the first branch 1 or the third branch 3 .

[0040] The first switch 5 and the second switch 6 can be linked, and the connected or disconnected states of the first switch 5 and the second switch 6 are opposite, so that the second branch 2 can be selectively connected to the first branch 1 or the third branch 3. In other words, the first switch 5 and the second switch 6 can realize an interlocking function. For example, the first switch 5 is closed and the second switch 6 is opened to connect the first branch 1 and the second branch 2 and disconnect the second branch 2 from the third branch 3. Alternatively, the second switch 6 is closed and the first switch 5 is opened to disconnect the first branch 1 and the second branch 2 and connect the second branch 2 to the third branch 3. This setting only requires a single command operation to simultaneously control the first switch 5 and the second switch 6, which can simplify the operation of switching charging modes, reduce the difficulty of switching charging modes, and make it more convenient for users to operate. In addition, the first switch 5 and the second switch 6 can be interlocked to improve the reliability of the charging device 100.

[0041] As some embodiments of the present application, the vehicle may include a first charging socket and a second charging socket, the first charging socket being connected to the first branch 1, the second charging socket being connected to the second branch 2, the controller being connected to the third branch 3, and the first charging socket being connected to the controller. When the first switch 5 is closed and the second switch 6 is open, the first branch 1 and the second branch 2 are connected and the second branch 2 and the third branch 3 are disconnected, so that the first charging socket and the second charging socket are connected in parallel to form a charging communication loop, at which point the charging device 100 is in a single-pile dual-gun charging mode. In another case, when the second switch 6 is closed and the first switch 5 is open, the first branch 1 and the second branch 2 are disconnected and the second branch 2 and the third branch 3 are connected, so that the first charging socket and the second charging socket are independently connected to the controller to form two independent charging communication loops, at which point the charging device 100 is in a dual-pile independent charging mode.

[0042] In some embodiments of the present invention, Figure 1 As shown, the vehicle charging device 100 further includes: a control member 8 , which is connected to both the first switch 5 and the second switch 6 , and is used to control the states of the first switch 5 and the second switch 6 .

[0043] Among them, the control part 8 of the charging device 100 is connected to the first switch 5 and the second switch 6, and the status of the first switch 5 and the second switch 6 can be controlled by the control part 8 of the charging device 100. The control part 8 can be a manual button, a manual knob, a touch screen in the car, etc., wherein the manual button, manual knob, etc. can be set in the car, and the manual button, manual knob, etc. can also be set next to the charging socket of the vehicle. The status of the first switch 5 and the second switch 6 can be controlled by triggering the control part 8, or the control part 8 can be an electrical control part, and the control part 8 can be triggered by voice, mobile phone APP input instructions, etc. to control the status of the first switch 5 and the second switch 6, and then the working mode of the vehicle's charging device 100 can be switched, so that the instruction to switch the charging mode can be implemented simply and quickly, which can improve the user's car experience.

[0044] As some embodiments of the present application, multiple control components 8 can be set on the vehicle. For example, the working mode of the vehicle's charging device 100 can be switched through a manual button located next to the charging socket, and the working mode of the vehicle's charging device 100 can be switched through the touch screen in the vehicle, so that the vehicle's charging device 100 is more convenient to use, so as to attract more users to choose a vehicle equipped with the vehicle charging device 100 proposed by the utility model.

[0045] In some embodiments of the present invention, Figure 1 As shown, the vehicle charging device 100 further includes: a third switch 7 , which is arranged on the fourth branch 4 , and is connected to the control member 8 .

[0046] Among them, the third switch 7 of the vehicle's charging device 100 can be set on the fourth branch 4, and the third switch 7 is connected to the control member 8. The state of the third switch 7 can be controlled by the control member 8 to control the fourth branch 4 to be disconnected or connected. The controller can determine the working mode of the charging device 100 based on whether the fourth branch 4 is disconnected or connected.

[0047] It should be noted that the third switch 7 is connected or disconnected synchronously with the first switch 5 or the second switch 6. For example, when the first switch 5 is closed, the third switch 7 is also closed, and when the first switch 5 is opened, the third switch 7 is also opened.

[0048] As some embodiments of the present application, when the first switch 5 and the third switch 7 are closed and the second switch 6 is open, the first branch 1 and the second branch 2 are connected and the second branch 2 is disconnected from the third branch 3, so that the first charging socket and the second charging socket are connected in parallel to form a charging communication loop, and the fourth branch 4 is connected, and the controller receives a level signal. At this time, the charging device 100 is in a single-pile dual-gun charging mode. When the second switch 6 is closed and the first switch 5 and the third switch 7 are open, the first branch 1 and the second branch 2 are disconnected and the second branch 2 is connected to the third branch 3, so that the first charging socket and the second charging socket are independently connected to the controller to form two independent charging communication loops, and the fourth branch 4 is disconnected, and the controller recognizes an invalid level signal. At this time, the charging device 100 is in a dual-pile independent charging mode.

[0049] By providing the third switch 7, it is possible to easily control the on and off of the fourth branch 4. Moreover, by connecting the third switch 7 to the operating member 8, the states of the first switch 5, the second switch 6, and the third switch 7 can be simultaneously controlled by the operating member 8 alone, thereby enabling the instruction to switch the charging mode to be implemented simply and quickly, thereby improving the user's car experience.

[0050] In some embodiments of the present invention, Figure 1 As shown, the first branch 1 includes a first sub-branch 11 and a second sub-branch 12, the second branch 2 includes a third sub-branch 21 and a fourth sub-branch 22, and the first switch 5 includes a first sub-switch 51 and a second sub-switch 52. The first sub-branch 11 and the third sub-branch 21 are selectively connected through the first sub-switch 51, and the second sub-branch 12 and the fourth sub-branch 22 are selectively connected through the second sub-switch 52. The first sub-switch 51 and the second sub-switch 52 are in the same state and operate synchronously.

[0051] Among them, the first sub-switch 51 can be used to control the selective connection between the first sub-branch 11 and the third sub-branch 21, and the second sub-switch 52 can be used to control the selective connection between the second sub-branch 12 and the fourth sub-branch 22. The first sub-switch 51 and the second sub-switch 52 have the same state and act synchronously (the first sub-switch 51 and the second sub-switch 52 are closed and opened at the same time). That is to say, the first sub-switch 51 and the second sub-switch 52 can simultaneously control the connection or disconnection of the corresponding branches. By setting the first sub-switch 51 and the second sub-switch 52, a reliable communication circuit can be formed to make the circuit design reasonable and the response smooth.

[0052] In some embodiments of the present invention, Figure 1As shown, the third branch 3 includes a fifth sub-branch 31 and a sixth sub-branch 32, the second switch 6 includes a third sub-switch 61 and a fourth sub-switch 62, the fifth sub-branch 31 and the third sub-branch 21 are selectively connected through the third sub-switch 61, the sixth sub-branch 32 and the fourth sub-branch 22 are selectively connected through the fourth sub-switch 62, and the third sub-switch 61 and the fourth sub-switch 62 are in the same state and operate synchronously.

[0053] Among them, the third sub-switch 61 can be used to control the selective connection between the third sub-branch 21 and the fifth sub-branch 31, and the fourth sub-switch 62 can be used to control the selective connection between the fourth sub-branch 22 and the sixth sub-branch 32. The third sub-switch 61 and the fourth sub-switch 62 are in the same state and act synchronously (the third sub-switch 61 and the fourth sub-switch 62 are closed and opened at the same time). That is, the third sub-switch 61 and the fourth sub-switch 62 can simultaneously control the connection or disconnection of the corresponding branches. By setting the third sub-switch 61 and the fourth sub-switch 62, a reliable communication loop can be formed to make the circuit design reasonable and the response smooth.

[0054] In some embodiments of the present invention, Figure 1 As shown, the first branch 1, the second branch 2, the third branch 3, and the fourth branch 4 are all constructed as CAN (Controller Area Network) communication harnesses.

[0055] Among them, the CAN communication harness can set the charging device 100 to multiple branches that work independently and do not interfere with each other. The first branch 1, the second branch 2, the third branch 3, and the fourth branch 4 are all constructed as CAN communication harnesses, which can achieve a more flexible modular design. The CAN communication harness is reliable, flexible, stable, and has a fast transmission rate, which can improve the overall reliability and response rate of the charging device 100.

[0056] In some embodiments of the present invention, Figure 1 As shown, the vehicle charging device 100 also includes: a connector 9 and a shell 10. The first branch 1, the second branch 2, the third branch 3, and the fourth branch 4 are all arranged in the shell 10. The connector 9 is arranged in the shell 10 and is connected to the first branch 1, the second branch 2, the third branch 3, and the fourth branch 4. The charging device 100 is suitable for being connected to the vehicle's charging socket and the vehicle's controller through the connector 9.

[0057] The first branch 1, the second branch 2, the third branch 3, the fourth branch 4, the first switch 5, the second switch 6, and the third switch 7 can all be located within the housing 10. The housing 10 can secure and protect the various components and circuits to reduce the risk of damage. The connector 9 can be disposed within the housing 10, or it can be disposed outside the housing 10 and connected to the housing 10, or a portion of the connector 9 can be disposed within the housing 10. The connector 9 can connect to the first branch 1, the second branch 2, the third branch 3, and the fourth branch 4. The vehicle's charging socket and the vehicle's controller can both be electrically connected to the charging device 100 via the connector 9. By providing the connector 9 within the vehicle's charging device 100, the charging device 100 can be electrically connected to the vehicle's charging socket and the vehicle's controller, thereby realizing the functions of the vehicle's charging device 100 and achieving a higher level of integration.

[0058] The charging socket includes a first charging socket and a second charging socket.

[0059] According to an embodiment of the present invention, a vehicle includes the charging device 100 of the vehicle of the above embodiment. By enabling the second branch 2 to be selectively connected to the first branch 1 or the third branch 3, and enabling the fourth branch 4 connected to the vehicle controller to be selectively turned on or off, the charging device 100 can be switched between a single-pile dual-gun charging mode and a dual-pile independent charging mode, so that the vehicle can select different charging modes according to actual needs through the charging device 100, which can broaden the vehicle's charging scenarios and enhance the user's vehicle experience.
