[0029] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.
[0030] Reference below Figure 1 A vehicle charging apparatus 100 and a vehicle having the same according to an embodiment of the present invention will be described.
[0031] like Figure 1As shown, a charging device 100 for a vehicle according to an embodiment of the present invention 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 being connected to a controller of the vehicle, 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 off states, so that the charging device 100 switches to a 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 another of the turned on or off states, so that the charging device 100 switches to a 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, and 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, and 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 controller of the vehicle, 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 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 turned on or off state, and the charging device 100 corresponds to the other working mode 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 working state (single-pile dual-gun 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 loop, and 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 the controller can determine that the charging device 100 is in the single-pile dual-gun charging mode. In the second working 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 loops, and the fourth branch 4 is turned on, and the fourth branch 4 transmits a valid level signal to the controller. The controller can use the valid level 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 the present 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 the single-pile dual-gun charging mode and the dual-pile independent charging mode. By controlling the two charging modes of the charging device 100 by the first switch 5 and the second switch 6, the difficulty of switching the charging mode can be reduced, and the command of 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] Among them, 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, that is, the first switch 5 and the second switch 6 can realize the interlocking function. For example, the first switch 5 is closed and the second switch 6 is opened, so that the first branch 1 and the second branch 2 are connected and the second branch 2 is disconnected from the third branch 3, or the second switch 6 is closed and the first switch 5 is opened, so that the first branch 1 and the second branch 2 are disconnected and the second branch 2 is connected to the third branch 3. In this setting, only one instruction operation is required to simultaneously control the first switch 5 and the second switch 6, which can simplify the operation of switching the charging mode, reduce the difficulty of switching the charging mode, 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 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. When the first switch 5 is closed and the second switch 6 is opened, 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, and 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 opened, 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, and 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 member 8 of the charging device 100 is connected to both the first switch 5 and the second switch 6, and the states of the first switch 5 and the second switch 6 can be controlled by the control member 8 of the charging device 100. The control member 8 can be a manual button, a manual knob, a touch screen in the vehicle, etc., wherein the manual button, the manual knob, etc. can be set in the vehicle, and the manual button, the manual knob, etc. can also be set next to the charging socket of the vehicle. The states of the first switch 5 and the second switch 6 can be controlled by triggering the control member 8, or the control member 8 can be an electrical control component, and the control member 8 can be triggered by voice, mobile phone APP input instructions, etc. to control the states of the first switch 5 and the second switch 6, and then the working mode of the charging device 100 of the vehicle can be switched, so that the instruction to switch the charging mode can be simply and quickly implemented, 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 by a manual button located next to the charging socket, and the working mode of the vehicle's charging device 100 can be switched by a touch screen in the vehicle, so that the vehicle's charging device 100 is easier to use, so as to attract more users to choose a vehicle equipped with the vehicle charging device 100 proposed in the present invention.
[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 disposed 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 according to 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 opened, 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 which 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 opened, 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, and the fourth branch 4 is disconnected, and the controller recognizes an invalid level signal, at which time the charging device 100 is in a dual-pile independent charging mode.
[0049] By setting the third switch 7, it is convenient to control the on and off of the fourth branch 4, and 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, so that the instruction of switching the charging mode can be implemented simply and quickly, which can improve the user's car experience.

[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 are in 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 corresponding branches to be connected or disconnected. By setting the first sub-switch 51 and the second sub-switch 52, a reliable communication loop 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 is selectively connected to the third sub-branch 21 through the third sub-switch 61, the sixth sub-branch 32 is selectively connected to the fourth sub-branch 22 through the fourth sub-switch 62, and the third sub-switch 61 and the fourth sub-switch 62 are in the same state and act 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 to say, the third sub-switch 61 and the fourth sub-switch 62 can simultaneously control the corresponding branches to be connected or disconnected. 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.

[0055] Among them, the CAN communication harness can set the charging device 100 into 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.

The plug connector 9 can be arranged in the housing 10, the plug connector 9 can be arranged outside the housing 10 and connected to the housing 10, or a part of the structure of the plug connector 9 can be arranged in the housing 10. The plug connector 9 can be connected to the first branch 1, the second branch 2, the third branch 3, and the fourth branch 4. The charging socket of the vehicle and the controller of the vehicle can be electrically connected to the charging device 100 through the plug connector 9. By arranging the plug connector 9 in the charging device 100 of the vehicle, it is convenient to electrically connect the charging device 100 with the charging socket of the vehicle and the controller of the vehicle to realize the function of the charging device 100 of the vehicle, so as to make the charging device 100 more integrated.
