[0044] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0046] With the development of science and technology, cars are becoming more and more intelligent and electric. The batteries of new energy vehicles need to power the low-voltage system of the whole vehicle when the vehicle is locked. Therefore, long-term parking of the vehicle may cause power feeding. At the same time, vehicle keys are becoming more and more diverse, upgrading from traditional mechanical keys to more convenient mobile phone Bluetooth keys, near field communication (NFC) cards, etc. Therefore, vehicle power feeding will mean that the vehicle cannot be unlocked and cannot be used. It can only be mechanically unlocked or forcibly unlocked to recharge the battery.

[0047] In the prior art, there are two methods for recharging batteries:

[0048] (I) A solution to jump-charging the battery using the auxiliary power interface A+ of the DC charging socket: the system electrically connects the charging device to the DC to DC converter (DC / DC), the vehicle electronic control module (Battery Energy Control Module, BECM) and the vehicle control unit (VCU), and the charging device supplies power to the VCU, BECM and DC / DC. The VCU determines that the battery is low on power and starts the battery charging process. After the charging is completed, the charging device is disconnected. This method requires that the vehicle has a fast charging port and a fast charging pile at the parking location, which has vehicle limitations and regional limitations.

[0049] (II) A solution to jump-charging the battery by adding an external power supply port after the vehicle is powered: the power supply port includes the power supply LA terminal and the power supply LB terminal; the five-door unlocking system and the anti-theft authentication system are powered by the power supply LA terminal, and the anti-theft authentication is triggered by pressing the door switch. If the authentication is passed, the door is opened and the vehicle battery is jumped; if the authentication is not passed, the door is not opened, and the vehicle battery is powered by the power supply LB terminal. This method requires the vehicle body to be re-molded, which is costly.

[0050] In summary, due to the limitation of charging conditions in the prior art, the efficiency of charging the vehicle battery is relatively poor.

[0051] In order to solve the problem of poor avoidance effect for cutting-in vehicles in the prior art, the embodiment of the present application provides a vehicle battery charging method, which can first obtain the battery voltage of the vehicle, and then, when the battery voltage is less than a preset voltage, open the AC charging port cover of the vehicle and start the charging circuit; finally, when a charging gun head is connected to the AC charging port, the battery is directly charged through the charging circuit based on an external portable charging device. In this way, the battery can be directly charged through the AC charging port of the vehicle, which improves the efficiency of charging the vehicle battery and avoids the situation where the vehicle cannot be unlocked due to insufficient battery voltage.

[0052] For ease of understanding, the vehicle battery charging method provided in this application is specifically introduced below with reference to the accompanying drawings.

[0053] Figure 1 is a flow chart of a vehicle battery charging method according to an exemplary embodiment. Figure 1 As shown, the vehicle battery charging method includes the following steps:

[0054] S101. Obtain the battery voltage of the vehicle.

[0055] In the embodiment of the present application, the above-mentioned vehicle is a new energy vehicle with an external AC charging port.

[0056] Exemplarily, the external charging interface is an AC charging socket specified by the national standard.

[0057] Exemplarily, the above-mentioned new energy vehicles include hybrid vehicles and pure electric vehicles.

[0058] In the embodiment of the present application, the standard voltage of the battery is 12 volts (Volt, V).

[0059] For example, the current voltage of the vehicle battery may be monitored in real time by a Super Vehicle Dynamics Control (SVDC).

[0060] S102: When the battery voltage is lower than a preset voltage, open the AC charging port cover and start the charging circuit.

[0061] In the embodiment of the present application, the above-mentioned preset voltage is an artificially set threshold value, which can be flexibly adjusted according to actual scenarios.

[0062] Exemplarily, the preset voltage may be 11.5V.

[0063] For example, the preset voltage is 11.5 V. If the SVDC detects that the current voltage of the battery is 11 V, the AC charging port cover is automatically opened and the charging circuit is started.

[0064] In the embodiment of the present application, the battery voltage is lower than the preset voltage, which may cause the vehicle to be unable to enter a high-voltage state and thus unable to start normally.

[0065] In the embodiment of the present application, the above-mentioned power replenishment circuit is used to replenish the battery so that the battery voltage returns to normal.

[0066] S103: When the AC charging port is connected to a charging gun, the battery is charged based on an external portable charging device and a charging circuit.

[0067] In the embodiment of the present application, the above-mentioned AC charging port is the AC charging socket specified in the above-mentioned national standard.

[0068] In the embodiment of the present application, the charging gun head may be an AC charging socket connection tool.

[0069] For example, Figure 2 As shown, the AC charging socket connection tooling includes 7 holes, including 5 large holes and 2 small holes.

[0070] In addition, the above-mentioned AC charging socket connection tooling also includes a positive terminal and a negative terminal.

[0071] In the embodiment of the present application, the above-mentioned external portable power supply device includes a jump-start power bank and a charger.

[0072] Exemplarily, when SVDC detects that an AC charging socket connection tool is inserted into the above-mentioned AC charging socket, and detects that the positive terminal of the AC charging socket connection tool is connected to the positive pole of the jumper pack, and the negative terminal of the AC charging socket connection tool is connected to the negative pole of the jumper pack, it indicates that the power replenishment circuit is normally connected, and the battery is now recharged through the power replenishment circuit.

[0073] In some embodiments, in order to provide necessary conditions for battery charging, such as Figure 3 As shown, in the above step S102, "opening the AC charging port cover and starting the charging circuit" may include the following steps:

[0074] S102a, driving the motor via the battery to open the AC charging port cover.

[0075] In an embodiment of the present application, the motor is a small motor, and a starting voltage of the small motor is less than the preset voltage.

[0076] Exemplarily, the SVDC may control the battery to supply power to the motor, so as to drive the motor to open the AC charging port cover.

[0077] S102b, closing the target switch from the AC charging contact to the power replenishment contact, and opening the power replenishment circuit.

[0078] In the embodiment of the present application, the target switch is a single-pole double-throw switch.

[0079] For example, Figure 4 As shown, the target switch is switch 1, the above-mentioned AC charging contact is contact 1, and the cedar power supply contact is contact 2. SVDC controls switch 1 from contact 1 to contact 2 through control line 1, disconnects the control pilot (CP) signal line, and switches to the power supply cable with charging capability.

[0080] It should be noted that the specifications of the above-mentioned power supply cable are: 20V, 20 amperes (Ampere, A).

[0081] In this way, when the battery voltage is lower than the preset voltage, the AC charging port cover can be automatically opened, and the AC charging circuit can be switched to the charging circuit, providing the necessary conditions for charging the battery.

[0082] In some embodiments, in order to extend the service life of the battery, Figure 5 As shown, after the above step S103, the vehicle battery charging method provided in the embodiment of the present application may further include the following steps:

[0083] S104: When the health of the battery is less than a preset health, the battery is repaired based on an external portable charging device and a charging circuit.

[0084] In the embodiment of the present application, the health of the battery being less than a preset health indicates that the vehicle needs to enter a maintenance mode to repair the battery.

[0085] In the embodiment of the present application, the above-mentioned preset health level is an artificially set value, which can be flexibly adjusted according to the actual usage scenario.

[0086] Exemplarily, the preset health level may be 95%.

[0087] For example, if the preset health level is 95%, if the SVDC detects that the health level of the battery is 90%, it indicates that the battery needs to be repaired. At this time, the charging circuit is kept unchanged, and the battery health level is repaired through the charging circuit by the charger.

[0088] S105: When the health level is greater than or equal to the preset health level, close the target switch from the power supply contact to the AC charging contact to open the AC charging circuit.

[0089] In the embodiment of the present application, the charging voltage of the above-mentioned AC charging circuit is 220V.

[0090] For example, in combination Figure 4 SVDC monitors the health of the battery in real time. After the health of the battery is restored to greater than 95%, the control switch 1 can be switched from contact 2 to contact 1 to turn on the CP signal line to switch from the power replenishment circuit to the AC charging circuit.

[0091] In this way, after the battery is recharged, if the health of the battery is less than a preset health, the health of the battery can be repaired, thereby extending the service life of the battery.

[0092] In addition, SVDC can switch from the charging circuit to the AC charging circuit only after detecting that the health of the above-mentioned battery has been restored to 100%, thereby further extending the service life of the battery.

[0093] In some embodiments, in order to ensure the normal power supply use of the vehicle, such as Figure 6 As shown, after the above step S103, the vehicle battery charging method provided in the embodiment of the present application may further include the following steps:

[0094] S106: When the battery health is greater than or equal to a preset health, detect whether the vehicle is unlocked.

[0095] In the embodiment of the present application, whether the vehicle is unlocked refers to whether the vehicle door can be opened.

[0096] Exemplarily, when the SVDC detects that the vehicle is not in the maintenance mode, it determines whether the door of the vehicle can be opened to allow the entire vehicle to enter high pressure.

[0097] S107: When the vehicle is unlocked successfully, the target switch is closed from the power supply contact to the AC charging contact to open the AC charging circuit.

[0098] For example, in combination Figure 4 When SVDC detects that the vehicle door can be opened, it can switch the control switch 1 from contact 2 to contact 1, so that the CP signal line is turned on to switch from the power supplement circuit to the AC charging circuit.

[0099] In this way, after the battery is recharged, it can be determined whether the vehicle has been successfully unlocked, and if the unlocking is successful, the recharge circuit can be switched to the AC charging circuit to ensure the normal power supply and use of the vehicle.

[0100] In some embodiments, to further ensure that the battery voltage can support successful vehicle unlocking, such as Figure 7 As shown, after the above step S106, the vehicle battery charging method provided in the embodiment of the present application may further include the following steps:

[0101] S108. When the vehicle is not unlocked successfully and the battery voltage is less than a preset voltage, the charging circuit is maintained, and the battery is charged based on an external portable charging device and the charging circuit.

[0102] For example, the preset voltage is 11.5 V. If the SVDC detects that the vehicle door cannot be opened and the battery voltage is 11.2 V, the charging circuit is kept unchanged, and the battery is continuously charged through the charging circuit by the jump-start battery.

[0103] In this way, after the battery is recharged, if the vehicle fails to be unlocked successfully, the battery will continue to be recharged when it is detected that the battery voltage is less than the preset voltage, further ensuring that the battery voltage can support successful unlocking of the vehicle.

[0104] In addition, if the vehicle is not unlocked successfully and the battery voltage is greater than or equal to the preset voltage, the target switch is closed from the power replenishment contact to the AC charging contact to open the AC charging circuit.

[0105] The following is an exemplary description of the overall implementation process of the vehicle battery charging method provided by the present application:

[0106] For example, Figure 8 As shown, the overall implementation process of the above vehicle battery charging method may include the following steps:

[0107] S201, SVDC determines whether the battery is feeding power, if so, execute step S202; if not, end the process.

[0108] Exemplarily, the above-mentioned power feeding means that the battery voltage is less than the above-mentioned preset voltage.

[0109] S202, SVDC opens the AC charging port cover and starts the charging circuit.

[0110] Exemplarily, the SVDC drive motor opens the AC charging port cover.

[0111] S203, recharge the battery via a charging circuit using a jump-start power bank.

[0112] Exemplarily, the jump-start power bank is connected to the AC charging port via an AC charging socket connection tool.

[0113] S204, SVDC determines whether the vehicle is in maintenance mode, if so, execute step S206; if not, execute step S205.

[0114] Exemplarily, the maintenance mode indicates that the health of the battery is less than a preset health.

[0115] S205, SVDC determines whether the vehicle is unlocked, if so, execute step S209; if not, execute step S201.

[0116] S206. SVDC actively terminates the maintenance mode.

[0117] In the embodiment of the present application, by actively terminating the maintenance mode, the unlocking of the vehicle can be prioritized.

[0118] S207, determine whether a repair request is received, if so, execute step S208; if not, execute step S209.

[0119] Exemplarily, the above repair request is manually sent through a button inside the vehicle.

[0120] S208. Maintain the power replenishment circuit and repair the health of the battery through the power replenishment circuit by means of the charger.

[0121] Exemplarily, the charger is connected to the AC charging port via an AC charging socket connection tool.

[0122] S209 , the SVDC is switched from the power replenishment circuit to the AC charging circuit.

[0123] In this way, when SVDC recognizes that the vehicle is feeding power, the vehicle body charging port cover is unlocked; the vehicle AC charging circuit is switched to the battery charging circuit; an external portable charging device is connected to the slow charging port through an AC charging socket connection tool to charge the battery; when the vehicle controller SVDC recognizes that the vehicle is unlocked or the battery voltage is normal, the battery charging circuit is switched to the vehicle AC charging circuit. This solves the problem in the prior art that the vehicle battery cannot be charged in a portable and efficient manner when the vehicle door is locked.

[0124] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to realize the above functions, the vehicle battery charging device or electronic device includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software.

It should be noted that the division of modules in the embodiments of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation.
