[0037] It should be noted that enhancing a signal can be understood as amplifying the parameters of the signal (such as power or voltage), and attenuating a signal can be understood as reducing the parameters of the signal.

[0038] Next, the embodiments of the vehicle charging device, method, vehicle equipment, and storage medium provided by the embodiments of the present application will be described.

[0039] In a first aspect, the present embodiment provides a charging circuit for a vehicle. Referring to Figure 1 as shown, the charging circuit 10 of the vehicle may include at least two charging interfaces 101, a switching module 102 connected to the at least two charging interfaces 101, and a charging battery 103 connected to the switching module 102; the charging circuit 10 further includes a first detection module 104 and a control module 105.

[0040] The at least two charging interfaces 101 are configured to connect to a charging device 20;

[0041] The first detection module 104 is configured to detect the connection of the at least two charging interfaces 101 to obtain a connection signal 101A, and transmit the connection signal 101A to the control module 105; the connection signal 101A is used to indicate whether each of the at least two charging interfaces 101 is connected to a charging device.

[0042] The control module 105 is configured to control the switching module 102 based on the connection signal 101A, so that the switching module 102 and the at least two charging interfaces 101 form a target charging circuit, and charge the charging battery 103 through the target charging circuit.

[0043] Among them, for the at least two charging interfaces 101:

[0044] The present application embodiment does not specifically limit the number of the at least two charging interfaces 101, which can be determined according to actual needs. For example, the charging interface 101 here can be two, or three, four, etc.

[0045] The charging interface 101 is configured to externally connect to a charging device 20. The present application embodiment does not specifically limit the specific type and charging parameters of the charging interface 101, which can be configured according to actual needs. Exemplarily, the charging interface 101 here can be a high-voltage charging interface or an ultra-high-voltage charging interface or a low-voltage slow charging interface. In practice, the interface types of the at least two charging interfaces can be the same or different.

[0046] The present application embodiment does not specifically limit the deployment position of the at least two charging interfaces 101 in the vehicle, which can be configured according to actual needs. For example, in the case of including two charging interfaces 101, the two charging interfaces 101 can be deployed on the left and right sides of the vehicle equipment (front or rear). In the case of including four charging interfaces 101, two charging interfaces 101 can be deployed on the left and right sides in front of the vehicle equipment, and two charging interfaces 101 can be deployed on the left and right sides behind the vehicle equipment.

[0047] For the switching module 102: It is used to form a target charging circuit. The switching module 102 here can be multiple switches. The switches here can be single-pole double-throw switches or single-pole single-throw switches.

[0048] For the rechargeable battery 103, the embodiments of the present application do not limit the battery type, capacity, etc. of the rechargeable battery 103, and it can be configured according to actual needs.

[0049] Here, the charging interface 101 is used to connect to the charging device 20. The switching module 102 is connected to the charging interface 101, and the switching module 102 is connected to the rechargeable battery 103. Thus, the rechargeable battery 103 can be charged through the target charging circuit formed by the switching module 102 and the charging interface 101.

[0050] The connection between the switching module 102 and the rechargeable battery 103 can be a direct connection or an indirect connection through other devices (such as various switching devices, etc.).

[0051] For the first detection module 104:

[0052] The first detection module 104 is used to detect the access of at least two charging interfaces 101 to obtain an access signal 101A. The embodiments of the present application do not limit the specific implementation of the first detection module 104, and it can be configured according to actual needs. The first detection module 104 can be a voltage or current signal detection device, or it can also be a contact sensor.

[0053] Correspondingly, the access signal 101A can be a voltage or current signal, or a contact detection signal.

[0054] In a possible implementation manner, the first detection module 104 is a current or voltage detection device. Correspondingly, the access signal 101A can be a current value or a voltage value. If the current value of a certain charging interface is not zero or the voltage value is not infinite, it indicates that the charging device is connected to this charging interface. Otherwise, it indicates that the charging device is not connected to this charging interface.

[0055] In another possible implementation manner, the first detection module 104 is a contact sensor. Correspondingly, the access signal 101A can be a contact detection signal. If the contact sensor of a certain charging interface is pressed, the corresponding access signal 101A becomes a preset value, indicating that the charging device is connected to this charging interface. Otherwise, it indicates that the charging device is not connected to this charging interface.

[0056] The first detection module 104 is electrically connected to the control module 105, and the first detection module 104 also sends the access signal 101A to the control module 105.

[0057] For the control module 105:

[0058] Receive the access signal 101A sent by the first detection module 104, and control the switching module 102 based on the access signal 101A, so that the switching module 102 and at least two charging interfaces 101 form a target charging circuit, and charge the charging battery 103 through the target charging circuit.

[0059] Here, the specific control method is not specifically limited and can be configured according to actual needs.

[0060] Example 1: If the access signal 101A indicates that only one charging interface is connected to a charging device, the control module 105 can control the switching module 102 to form a charging circuit with a single charging interface between the switching module 102 and the charging interface 101, so as to charge the charging battery 103 through the charging circuit of the single charging interface.

[0061] Example 2: If the access signal 101A indicates that multiple charging interfaces are connected to a charging device, the control module 105 can control the switching module 102 to form a parallel charging circuit with multiple charging interfaces between the switching module 102 and the multiple charging interfaces, so as to charge the charging battery 103 through the charging circuit of the parallel charging circuit of the multiple charging interfaces.

[0062] Example 3: If the access signal 101A indicates that multiple charging interfaces are connected to a charging device, the control module 105 can control the switching module 102 to form a series charging circuit with multiple charging interfaces between the switching module 102 and the multiple charging interfaces, so as to charge the charging battery 103 through the charging circuit of the series charging circuit of the multiple charging interfaces.

[0063] Example 4: If the access signal 101A indicates that multiple charging interfaces are connected to a charging device, select a target charging interface from the multiple charging interfaces, and form a charging circuit with a single charging interface between the switching module 102 and the one target charging interface, so as to charge the charging battery 103 through the charging circuit of the single charging interface.

[0064] Example 5: If the access signal 101A indicates that multiple charging interfaces are connected to a charging device, select N target charging interfaces from the multiple charging interfaces, and the control module 105 can control the switching module 102 to form a series / parallel charging circuit with N charging interfaces between the switching module 102 and the N target charging interfaces, so as to charge the charging battery 103 through the series / parallel charging circuit of the N charging interfaces.

[0065] The embodiments of the present application do not specifically limit the deployment of the control module 105, which can be configured according to actual needs. Exemplarily, the control module 105 can be integrated into the controller in the battery management system, or can be separately deployed independently of the controller in the battery management system.

[0066] The charging circuit of the vehicle provided by the embodiment of the present application includes at least two charging interfaces, a switching module connected to the at least two charging interfaces, and a charging battery connected to the switching module; the charging circuit further includes a first detection module and a control module; the at least two charging interfaces are used to access a charging device; the first detection module is used to detect the access of the at least two charging interfaces to obtain an access signal, and transmit the access signal to the control module; the access signal is used to represent whether each of the at least two charging interfaces accesses a charging device; the control module is used to control the switching module based on the access signal, so that the switching module and the at least two charging interfaces form a target charging circuit, and the charging battery is charged through the target charging circuit.

[0067] In the solution of the present application, the charging circuit includes at least two charging interfaces. When charging is required, the first detection module can detect the access of the at least two charging interfaces to obtain an access signal, so as to obtain whether each of the at least two charging interfaces accesses a charging device. The control module controls the switching module and the at least two charging interfaces to form a target charging circuit according to the charging interface that accesses the charging device represented by the access signal, so as to charge the charging battery through the target charging circuit. It can be seen that since the charging circuit includes at least two charging interfaces, in practice, the charging battery can also be charged through the target charging circuit formed by the actually accessed charging device interfaces. Here, the charging interface that actually accesses the charging device can be one or more. Therefore, this solution expands the application scenarios of vehicle charging, and charging the charging battery through multiple charging interfaces can improve the charging efficiency of the charging battery.

[0068] Next, the specific structure of the switching module 102 will be described.

[0069] In a possible implementation manner, referring to Figure 2 the content shown, when the at least two charging interfaces 101 include a first charging interface 1011 and a second charging interface 1012, the switching module 102 includes: a first switch 1021 and a second switch 1022.

[0070] The first switch 1021 includes a first end 10211 and a second end 10212; the second switch 1022 includes a third end 10221, a fourth end 10222, and a fifth end 10223.

[0071] The first end 10211 is connected to the positive terminal 10111 of the first charging interface 1011, and the second end 10212 is connected to the positive terminal 10121 of the second charging interface 1012.

[0072] The third terminal 10221 is connected to the negative terminal 10112 of the first charging interface 1011, and the fourth terminal 10222 is connected to the positive terminal 10121 of the second charging interface 1012; the fifth terminal 10223 is connected to the negative terminal 10122 of the second charging interface 1012.

[0073] In this way, by controlling the first switch 1021 and the second switch 1022 to be turned off or on, different target charging circuits can be formed, which are simple and reliable to implement.

[0074] Next, the specific control process of the control module 105 will be described.

[0075] Specifically, it may include but is not limited to any one of the following cases 1 to 4.

[0076] Case 1: The first charging interface is connected to the first charging device, and the second charging interface is not connected to any charging device;

[0077] Case 2: The first charging interface is not connected to any charging device, and the second charging interface is connected to the second charging device;

[0078] Case 3: The first charging interface is connected to the first charging device, and the second charging interface is connected to the second charging device;

[0079] Case 4: Neither the first charging interface nor the second charging interface is connected to any charging device.

[0080] Next, Case 1 where the first charging interface is connected to the first charging device and the second charging interface is not connected to any charging device will be described.

[0081] If the access signal 101A indicates that the first charging interface 1011 is connected to the first charging device 201 and the second charging interface 1012 is not connected to any charging device 20;

[0082] Referring to Figure 3 the content shown, the control module 105 is specifically configured to: control the first switch 1021 to be turned off, and conduct the connection between the third terminal 10221 and the fifth terminal 10223 of the second switch 1022 to form the single charging circuit of the first charging interface; so as to charge the charging battery 103 through the first charging device 201 connected to the first charging interface 1011.

[0083] Here, turning off the first switch 1021 means disconnecting the connection between the first terminal 10211 and the second terminal 10212 of the first switch 1021.

[0084] The positive terminal 10111 of the first charging interface 1011 is connected to the positive terminal of the charging battery 103.

[0085] The positive terminal 10122 of the second charging interface 1012 is connected to the negative terminal of the charging battery 103.

[0086] It can be seen that when only the first charging interface is connected to the first charging device, the switching module can be controlled to form a single charging circuit of the first charging interface, and the battery can be charged through the single charging circuit of the first charging interface, which has the characteristics of simple and reliable implementation.

[0087] Next, a description will be given of Case 2 where the first charging interface is not connected to a charging device and the second charging interface is connected to the second charging device 202.

[0088] If the access signal 101A indicates that the first charging interface 1011 is not connected to a charging device and the second charging interface 1012 is connected to the second charging device 202;

[0089] Reference Figure 4 As shown in the content, the control module 105 is specifically configured to: control the first switch 1021 to conduct, and conduct the connection between the third terminal 10221 and the fourth terminal 10222 of the second switch 1022 to form a single charging circuit of the second charging interface; so as to charge the charging battery 103 through the second charging device 202 connected to the second charging interface 1012.

[0090] Here, conducting the first switch 1021 means conducting the connection between the first terminal 10211 and the second terminal 10212 of the first switch 1021.

[0091] The positive terminal 10111 of the first charging interface 1011 is connected to the positive terminal of the charging battery 103.

[0092] The positive terminal 10122 of the second charging interface 1012 is connected to the negative terminal of the charging battery 103.

[0093] It can be seen that when only the second charging interface is connected to the second charging device, the switching module can be controlled to form a single charging circuit of the second charging interface, and the battery can be charged through the single charging circuit of the second charging interface, which has the characteristics of simple and reliable implementation.

[0094] Next, a description will be given of Case 3 where the first charging interface is connected to the first charging device 201 and the second charging interface is connected to the second charging device 202.

[0095] If the access signal 101A indicates that the first charging interface 1011 is connected to the first charging device 201 and the second charging interface 1012 is connected to the second charging device 202.

[0096] Reference Figure 5 As shown in the content, the charging circuit 10 further includes a second detection module 106;

[0097] The second detection module 106 is configured to detect the required voltage of the rechargeable battery 103, the first charging voltage range of the first charging device 201, and the second charging voltage range of the second charging device 202;

[0098] The control module 105 is further configured to: determine whether the first charging voltage range and the second charging voltage range meet the required voltage, to obtain a first signal B; and control the first switch 1021 and the second switch 1022 based on the first signal B.

[0099] The positive terminal 10111 of the first charging interface 1011 is connected to the positive terminal of the rechargeable battery 103.

[0100] The positive terminal 10122 of the second charging interface 1012 is connected to the negative terminal of the rechargeable battery 103.

[0101] The first signal B is used to represent whether the first charging voltage range and the second charging voltage range meet the required voltage.

[0102] Regarding the second detection module 106:

[0103] The second detection module 106 may be a voltage detection device. Through the second detection module 106, the required voltage of the rechargeable battery 103, the first charging voltage range of the first charging device 201, and the second charging voltage range of the second charging device 202 can be detected.

[0104] It can be seen that when charging devices are connected to both the first charging interface and the second charging interface, a first signal can be further obtained based on the required voltage of the rechargeable battery, the first charging voltage range of the first charging device 201, and the second charging voltage range of the second charging device 202, so as to control the first switch 1021 and the second switch 1022 based on the first signal. In this way, for different first signals, the corresponding control schemes are different, which has the characteristics of wide application and high user experience.

[0105] Next, the process in which the control module 105 controls the first switch and the second switch based on the first signal in case 3 will be described.

[0106] In a possible implementation manner, when the first signal B represents that both the first charging voltage range and the second charging voltage range meet the required voltage, the control module 105 is further configured to:

[0107] Refer to Figure 6As shown in the figure, the first switch 1021 is controlled to conduct, and the connection between the third terminal 10221 and the fifth terminal 10223 of the second switch is conducted, forming a parallel charging circuit for the first charging interface 1011 and the second charging interface 1012; so as to charge the charging battery 103 through the first charging device 201 and the second charging device 202 connected in parallel.

[0108] Both the first charging voltage range and the second charging voltage range meet the required voltage, which means that the first charging voltage range includes the required voltage and the second charging voltage range includes the required voltage.

[0109] It can be seen that in this case, not only the charging application scenario is improved, but also the parallel charging can further improve the charging efficiency.

[0110] In another possible implementation manner, when the first signal B indicates that both the first charging voltage range and the second charging voltage range are lower than the required voltage, the control module 105 is further configured to:

[0111] Refer to Figure 7 As shown in the figure, the first switch 1021 is controlled to disconnect, and the connection between the third terminal 10221 and the fourth terminal 10222 of the second switch 1022 is conducted, forming a series charging circuit for the first charging interface 1011 and the second charging interface 1012; so as to charge the charging battery 103 through the first charging device 201 and the second charging device 202 connected in series.

[0112] Since both the first charging voltage range and the second charging voltage range are lower than the required voltage and direct charging cannot be performed directly, forming a series charging circuit with the first charging interface 1011 and the second charging interface 1012 can increase the charging voltage and achieve direct charging of the charging battery 103.

[0113] It can be seen that in this case, the problem that both the first charging voltage range and the second charging voltage range are lower than the required voltage and direct charging cannot be performed directly is solved, and the charging application scenario is improved.

[0114] Next, the case where neither the first charging interface nor the second charging interface is connected to a charging device in Case 4 will be described.

[0115] If the access signal 101A indicates that neither the first charging interface 1011 nor the second charging interface 1012 is connected to a charging device;

[0116] Refer to Figure 8 As shown in the figure, the control module 105 is further configured to: disconnect the first switch 1021 and conduct the connection between the third terminal 10221 and the fourth terminal 10222 of the second switch 1022.

[0117] In this case, since neither the first charging interface nor the second charging interface is connected to a charging device, by controlling the first switch and the second switch, the first charging interface is positively charged and the second charging interface is negatively charged. The charging properties of the two charging interfaces are different, reducing the possibility of electric shock and having relatively high safety.

[0118] The charging circuit of the vehicle provided by the embodiment of the present application will be described below through specific scenarios.

[0119] With the large-scale application of new energy vehicles, there are great differences in the types of charging piles and vehicle voltage platforms in the market. In this state, charging adaptation cannot be completed for some specific charging piles or some specific vehicles, resulting in inconvenient usage scenarios for customers during vehicle use and causing customer complaints about vehicle use. This embodiment uses the series-parallel connection method of charging piles to supply energy to the charging piles, enriching the vehicle usage scenarios while simultaneously improving the charging efficiency.

[0120] In this embodiment, when the vehicle is in a charging station, a series-parallel structure of a high-voltage circuit connected by two guns is used to achieve fast charging.

[0121] Inside the vehicle high-voltage battery, when it is recognized that neither the A gun 901 nor the B gun 902 (equivalent to the above-mentioned first charging interface and second charging interface) is inserted (equivalent to the above-mentioned not being connected to a charging device), through the cooperation of switches (Switch, SW) 3, SW4, and SW5, the high-voltage connection of the battery pack 903 is completed, the SW1 (equivalent to the above-mentioned first switch) is disconnected, and the SW2 (equivalent to the above-mentioned second switch) is switched to position 1 (equivalent to the above-mentioned third terminal and fourth terminal being connected) for the vehicle user to use. Specifically, reference can be made to Figure 9 the content shown.

[0122] Inside the vehicle high-voltage battery, when it is recognized that the A gun 901 is inserted, through the cooperation of SW3, SW4, and SW5, the high-voltage connection of the battery pack 903 is completed, the SW2 is switched to position 2 (equivalent to the above-mentioned third terminal and fourth terminal being connected), so that the battery pack 903 is connected to the A gun 901, and the battery pack 903 is charged through the A gun 901.
