For example, the interactive information involved in the present application is obtained under full authorization.

[0060] Figure 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application, referring to Figure 1 , the implementation environment includes a power supply device 101 and a vehicle 102.

[0061] Optionally, the power supply device 101 includes but is not limited to a slow charging pile, a fast charging pile and the like, and the present application embodiment does not limit this.

[0062] Optionally, the vehicle 102 is an electric vehicle, such as a pure electric vehicle or a hybrid electric vehicle, etc. And the vehicle 102 can be a car, a taxi, an electric bicycle, etc. The present application embodiment does not limit this.

[0063] The vehicle 102 includes a vehicle-mounted charger and a battery, and the vehicle-mounted charger takes an alternating power supply as input and takes a direct current as output to charge the battery on the vehicle.

[0064] The power supply device 101 is provided with a power supply interface 1011, and the vehicle 102 is provided with a vehicle interface 1021. In the case that the power supply interface 1011 and the vehicle interface 1021 are connected, the power supply device 101 charges the vehicle 102.

[0065] Optionally, the connection mode between the power supply device 101 and the vehicle 102 is as shown in Figure 2 , referring to Figure 2The power supply socket and the power supply plug of the power supply device 101 form a power supply interface 1011, and the power supply socket and the power supply plug of the vehicle 102 form a vehicle interface 1021. When the power supply plug of the power supply device 101 is inserted into the power supply socket of the vehicle 102, the power supply interface 1011 is connected with the vehicle interface 1021, and the power supply device 101 charges the vehicle 102. In this embodiment of the application, the power supply device 101 is connected with the vehicle 102 through the power supply interface 1011 and the vehicle interface 1021. Figure 2 L1, L2 and L3 in the figure are AC power lines, N is a neutral line, PE is a ground line, CC is a connection confirmation line, and CP is a control pilot line.

[0066] In a normal charging process, an AC voltage signal is transmitted on the AC power line, a CC signal is transmitted on the CC signal line, and a CP signal is transmitted on the CP signal line.

[0067] In addition, the power supply device 101 further includes a residual current protector, a power supply control device and the like, and the vehicle 102 further includes an on-board charger and the like. The specific structure of the power supply device 101 and the vehicle 102 is not limited in this embodiment of the application.

[0068] Figure 3 is a flowchart of a vehicle charging method provided in this embodiment of the application. The execution subject of this embodiment of the application is a vehicle, and the vehicle includes a vehicle charger. Referring to Figure 3 , the method includes the following steps.

[0069] 301. In the case where the charging signal is detected to be abnormal, the on-board charger in the vehicle stops charging the vehicle and starts timing.

[0070] The charging signal includes at least one of a CC (Connection Confirmation) signal, a CP (Control Pilot) signal and an AC voltage signal.

[0071] The CC signal is a signal sent by the power supply device to the vehicle, and refers to a charging connection confirmation signal. When the CC signal is normal, the whole vehicle can normally charge. In the charging process, the CC signal is used to confirm the connection state of the power supply device and the vehicle. When the CC signal is normal, the vehicle detects that the power supply device has been correctly connected, and then informs the vehicle to start charging. Alternatively, different voltages of the CC signal represent different states. For example, when the voltage of the CC signal is 0V (Volt), it represents that the power supply device does not charge, and when the voltage of the CC signal is 6V, it represents that the power supply device supports the maximum charging power.

[0072] The CP signal is a signal sent by the vehicle to the power supply device, used to inform the power supply device of the support capability and charging mode of the vehicle. Optionally, different voltages of the CP signal represent different states. For example, when the voltage of the CP signal is 0V, it represents that the vehicle does not need to be charged; and when the voltage of the CP signal is 9V, it represents that the vehicle needs to be charged at a reduced power.

[0073] The AC voltage signal is an input voltage provided by the power supply device. The AC voltage signal can be a 220V AC voltage signal or a 380V AC voltage signal, etc. The charging mode of the vehicle includes fast charging and slow charging. The fast charging refers to charging the vehicle by using a DC voltage signal, and the slow charging refers to charging the vehicle by using an AC voltage signal. For the same vehicle, the charging time required by the slow charging is greater than the charging time required by the fast charging. The vehicle charging method provided in the embodiments of the present application is applied to a slow charging scenario.

[0074] In addition, the vehicle includes a vehicle-mounted charger. The vehicle-mounted charger is a charger fixedly installed on the vehicle. The vehicle-mounted charger can convert the AC voltage signal into a DC voltage signal, and uses the DC voltage signal to charge the vehicle. For example, the vehicle-mounted charger converts a 220V AC voltage signal into a 300V DC voltage signal.

[0075] In the embodiments of the present application, the vehicle detects the charging signal during the charging process, so as to determine whether the charging signal is normal or abnormal. In the case that the charging signal is detected to be abnormal, the charging of the vehicle is stopped.

[0076] Optionally, the vehicle detects the charging signal during the charging process, so as to determine whether the charging signal is normal or abnormal, including at least one of the following:

[0077] 1. The CC signal is sampled to detect whether the CC signal is normal in real time, i.e., whether the connection state between the power supply device and the vehicle is normal.

[0078] 2. The CP signal is sampled to detect whether the CP signal is normal in real time, i.e., whether the charging power of the power supply device is normal.

[0079] 3. The AC voltage signal is sampled to detect whether the AC voltage signal is normal in real time, i.e., whether the state of the AC input is normal.

[0080] The vehicle includes a battery, and the vehicle-mounted charger is connected to the battery. The vehicle-mounted charger charging the vehicle refers to the vehicle-mounted charger charging the battery in the vehicle. The battery can include at least one of a power battery or a storage battery. The power battery is a battery specially used for storing and releasing electric energy to drive the vehicle. The storage battery is a battery that stores electric energy in the form of chemical energy. The power battery is the main source of energy for driving the vehicle, and the storage battery is mainly used for the low-voltage system of the vehicle, such as the power supply of devices such as vehicle lights, vehicle windows, and audio equipment.

[0081] The three charging signals above all affect the charging process of the vehicle, and once any signal is abnormal, the vehicle charging can be affected. Therefore, in the embodiments of the present application, the three charging signals above are detected in real time, and in the case where any one or more charging signals are abnormal, the vehicle-mounted charger stops charging the vehicle. In addition, in order to accurately measure the abnormal duration of the charging signal, the timing starts as soon as the abnormality of the charging signal is detected. With the passage of time, the timing duration gradually increases, and the timing duration can represent the abnormal duration of the charging signal.

[0082] 302. In the case where the timing duration has reached the target duration and the charging signal has not returned to normal, the vehicle-mounted charger enters a sleep state.

[0083] In step 301, although the vehicle-mounted charger has stopped charging the vehicle, it is still in a working state, which will consume the power consumption of the vehicle and reduce the power of the vehicle. Therefore, in the case where the timing duration has reached the target duration and the charging signal has not returned to normal, it indicates that the abnormal duration of the charging signal is too long, and it is likely to take a long time to return to normal. Therefore, in order to save power consumption and power, the vehicle-mounted charger is switched from the working state to the sleep state.

[0084] The target duration can be 1 minute, 10 minutes, etc., which can be set by default by the vehicle-mounted charger or determined in other ways.

[0085] 303. In the case where the charging signal returns to normal, the vehicle-mounted charger is awakened, and the vehicle-mounted charger resumes charging the vehicle.

[0086] The embodiments of the present application take the vehicle-mounted charger entering the sleep state in step 302 as an example. After the vehicle-mounted charger enters the sleep state, the charging signal is also detected. In the case where the charging signal returns to normal, the vehicle-mounted charger is awakened, i.e. the vehicle-mounted charger is switched from the sleep state to the working state, and the vehicle-mounted charger resumes charging the vehicle, thereby continuing the charging process.

[0087] Optionally, the timing duration represents the abnormal duration of the charging signal, and in the case where the charging signal returns to normal, the timing duration is cleared to zero so that the timing can start from zero when the charging signal is detected again.

[0088] The method provided in the embodiments of the present application stops the on-board charger from charging the vehicle in the case of detecting abnormal charging signals, effectively avoids the influence of abnormal charging signals, and improves charging reliability and user charging experience. Moreover, in the case that the abnormal duration of the charging signals has reached the target duration but the charging signals have not returned to normal, the on-board charger enters a dormant state, and the on-board charger is woken up after the charging signals return to normal, thereby saving the power consumption of the vehicle and avoiding unnecessary power consumption waste due to a long abnormal duration of the charging signals.

[0089] On the basis of the above-described embodiments, the embodiments of the present application further provide the following possible implementation manners.

[0090] 1. The charging signals include at least one of the CC signal, the CP signal and the AC voltage signal of the power supply device, and the on-board charger recovers to charge the vehicle in different manners for different types of charging signals.

[0091] In a possible implementation manner, the charging signals are the CC signal or the CP signal, and step 303 includes directly waking up the on-board charger in the case of detecting that the charging signals return to normal, and the on-board charger recovers to charge the vehicle.

[0092] In another possible implementation manner, the charging signals are the AC voltage signal, and step 303 includes waking up the on-board charger in the case of detecting that the charging signals return to normal and the vehicle and the power supply device are reconnected, and the on-board charger recovers to charge the vehicle.

[0093] That is, when the CC signal or the CP signal returns to normal after being abnormal, the on-board charger can be directly woken up without reconnection of the power supply device and the vehicle, thereby recovering to charge the vehicle. When the AC voltage signal returns to normal after being abnormal, the on-board charger cannot recover to the normal working state, and needs to be woken up after the power supply device and the vehicle are disconnected and then reconnected, thereby recovering to charge the vehicle.

[0094] 2. The vehicle includes the power battery and the storage battery, and the vehicle can stop charging both the power battery and the storage battery or can stop charging one of the batteries according to actual conditions.

[0095] In a possible implementation manner, the on-board charger stops charging the vehicle in the case of detecting abnormal charging signals, including stopping the on-board charger from charging both the power battery and the storage battery in the case of detecting abnormal charging signals. By stopping charging both the batteries, the influence of abnormal signals can be avoided to the greatest extent.

[0096] In another possible implementation, in the case that the charging signal abnormality is detected, the on-board charger stops charging the power battery and keeps charging the storage battery, including: in the case that the charging signal abnormality is detected, the on-board charger stops charging the power battery and keeps charging the storage battery. And the method further includes: after the on-board charger enters the hibernation state, the on-board charger stops charging the storage battery.

[0097] Since the power battery is the main energy source for driving the vehicle to travel, if the power battery is affected, the safe travel of the vehicle will be affected. The storage battery is mainly used for power supply of various devices of the vehicle, and has less impact on the safe travel of the vehicle. Therefore, in the case that the charging signal abnormality is detected, the charging of the power battery is stopped first, and the charging of the storage battery is kept, so as to minimize the impact of the charging signal abnormality as much as possible, and to keep the charging process as much as possible, and avoid that the charging speed is greatly affected.

[0098] In this case, in the case that the charging signal is detected to be normal, the on-board charger resumes charging the power battery. Or, in the case that the time length has reached the target time length, but the charging signal has not returned to normal, the on-board charger enters the hibernation state, at which time the charging of the storage battery is stopped, thereby fully saving energy consumption.

[0099] 3, The vehicle is associated with the electronic device, and the two can communicate with each other by using wireless communication technologies such as Wi-Fi (mobile hotspot) technology and Bluetooth technology. Therefore, when the on-board charger needs to be switched to the hibernation state, the on-board charger can be first confirmed through the electronic device.

[0100] Therefore, in one possible implementation, the step 302 includes: in the case that the time length has reached the target time length and the charging signal has not returned to normal, sending a hibernation confirmation request to an electronic device associated with the vehicle, the hibernation confirmation request being used to request confirmation of the on-board charger entering the hibernation state, and the on-board charger entering the hibernation state in response to a hibernation confirmation response sent by the electronic device.

[0101] The electronic device can include devices such as mobile phones, tablet computers, smart watches, and smart speakers, and the embodiments of the present application do not limit the same.

[0102] The vehicle sends a hibernation confirmation request to the electronic device, and the hibernation confirmation request is used to request confirmation of the on-board charger entering the hibernation state. The electronic device can output the hibernation confirmation request, for example, display the hibernation confirmation request on the display screen of the electronic device, or broadcast the voice of the hibernation confirmation request, etc. The user of the electronic device can understand that the time length of the charging signal abnormality has exceeded the target time length by checking the hibernation confirmation request, and needs to decide whether to switch the on-board charger to the hibernation state. Then, according to different user operations, the following three cases can be divided:

[0103] Case 1, the user agrees to the hibernation confirmation request on the electronic device, the electronic device sends a hibernation confirmation response to the vehicle, the hibernation confirmation response indicates that the user agrees to the vehicle-mounted charger entering the hibernation state, and in the case of receiving the hibernation confirmation response, the vehicle-mounted charger enters the hibernation state in response to the hibernation confirmation response.

[0104] This case is suitable for a scenario in which the user determines that the charging signal cannot be restored to normal in a short time or cannot determine when the charging signal is restored to normal. At this time, the vehicle-mounted charger entering the hibernation state can effectively save power consumption.

[0105] Case 2, the user does not operate on the electronic device for the hibernation confirmation request. In the case that the vehicle does not receive the response sent by the electronic device, the vehicle-mounted charger does not enter the hibernation state, but remains in the working state and waits for the charging signal to be restored to normal.

[0106] For example, after the vehicle sends the hibernation confirmation request to the electronic device, the waiting time reaches the preset time length, but the response sent by the electronic device has not been received, indicating that the vehicle-mounted charger does not need to be switched to the hibernation state.

[0107] Case 3, the user rejects the hibernation confirmation request on the electronic device, the electronic device sends a hibernation rejection response to the vehicle, the hibernation rejection response indicates that the user rejects the vehicle-mounted charger entering the hibernation state, and in the case of receiving the hibernation rejection response, the vehicle-mounted charger remains in the working state and waits for the charging signal to be restored to normal in response to the hibernation rejection response.

[0108] This case is suitable for a scenario in which the user determines that the charging signal will be restored to normal soon. Since the vehicle-mounted charger enters the hibernation state and then wakes up, the two state switching processes still consume time and power. In the case that the charging signal is restored to normal in a short time, it is unnecessary to perform the two state switching processes, and it is directly waited for the charging signal to be restored to normal.

[0109] In the embodiments of the present application, the vehicle sends a hibernation confirmation request to the electronic device, and whether the vehicle-mounted charger is switched to the hibernation state is determined according to the feedback of the user to the hibernation confirmation request, which improves flexibility, is more in line with the current actual situation, and can more effectively adopt the most power-saving processing mode.

[0110] 4, in the case of abnormal charging signal, not only the vehicle-mounted charger stops charging the vehicle, but also a decision mode is provided, which can determine the state of the vehicle-mounted charger according to the abnormal time length of the charging signal. The vehicle can directly adopt the decision mode, or can determine whether to adopt the decision mode for decision according to the current state.

[0111] In a possible implementation, the step 301 comprises: in the case that the charging signal is detected to be abnormal, the on-board charger stops charging the vehicle. In the case that the current time belongs to the historical power consumption time period, or in the case that the remaining power of the battery of the vehicle is less than the target power, the timing is started.

[0112] That is, in the case that the charging signal is abnormal, the on-board charger stops charging the vehicle, and meanwhile, the on-board charger still maintains the working state. At this time, the vehicle determines whether to make the above decision according to the current state.

[0113] For example, the vehicle acquires the current time, and determines whether the current time belongs to the historical power consumption time period. If yes, it indicates that the above decision mode is to be adopted, and therefore the timing is started. Subsequently, the working state of the on-board charger can be maintained based on the timing duration, or the steps 302-303 are performed, in the case that the timing duration has not reached the target duration.

[0114] The historical power consumption time period is determined based on the historical use record of the vehicle, and indicates that the power consumption of the vehicle in the historical power consumption time period is greater in the historical habit of using the vehicle of the user, that is, the power consumption of the vehicle in the historical power consumption time period is greater than that in other time periods. For example, the historical use record of the vehicle is acquired, the historical use record includes the power corresponding to at least one time point in a plurality of periods, or the consumed power corresponding to at least one time period, and the like. Each period is divided into a plurality of time periods, and based on the historical use record, the historical power consumption time period can be determined from the plurality of time periods. For example, the historical power consumption time period of the vehicle of a certain user is the working time period from 8:00 to 9:00 in the morning and the commuting time period from 6:00 to 7:00 in the evening.

[0115] If the current time belongs to the historical power consumption time period, it indicates that according to the habit of using the vehicle of the user, the user needs to use the vehicle in the current time period and needs to consume more power. If the current charging signal is abnormal, the power consumption should be saved, and the remaining power of the vehicle should be saved as much as possible. Therefore, the timing is started, and subsequently, the working state of the on-board charger is maintained based on the timing duration, or the steps 302-303 are performed, in the case that the timing duration has not reached the target duration.

[0116] If the current time does not belong to the historical power consumption time period, it indicates that according to the habit of using the vehicle of the user, the user uses the vehicle less in the current time period and needs to consume less power. Therefore, the timing is not started, and the state of the on-board charger does not need to be determined based on the timing duration. The working state of the on-board charger only needs to be maintained. Subsequently, when the charging signal is restored to be normal, the on-board charger resumes charging the vehicle.

[0117] Exemplarily, the vehicle acquires the current residual capacity of the battery, and in the case that the residual capacity of the battery is less than the target capacity, it indicates that the residual capacity of the vehicle is too small, which may affect the subsequent use of the vehicle by the user, and if the current charging signal has a problem, power consumption should be saved as much as possible to save the residual capacity of the vehicle, and therefore timing is started. Subsequently, based on the timing duration, in the case that the timing duration has not reached the target duration, the working state of the on-board charger is maintained, or steps 302-303 are performed.

[0118] In the case that the residual capacity of the battery is not less than the target capacity, it indicates that the residual capacity of the vehicle is still relatively sufficient, and the subsequent use of the vehicle by the user is not particularly affected, and therefore timing is not performed, and the state of the on-board charger is not determined based on the timing duration, and only the working state of the on-board charger needs to be maintained. Subsequently, after the charging signal is restored to normal, the on-board charger is restored to charging the vehicle.

[0119] In the embodiments of the present application, not only a decision-making manner according to the abnormal duration of the charging signal is provided, but also whether the above decision-making manner is to be used is determined according to the current time or the current residual capacity, which improves flexibility and adaptively processes according to the actual state of the vehicle, and considers the needs of saving power consumption and simplifying operation from multiple aspects, thereby meeting the individualized needs of users and improving user experience.

[0124] 3. In the charging process, the alternating voltage signal detection module samples the alternating voltage signal to determine whether the alternating voltage signal is normal.

[0125] 4. If any of the three detection modules determines that the detected signal is abnormal, the control module will stop the on-board charger from charging the power battery and the storage battery, and start timing. The three detection modules will continue to perform signal detection.

[0126] 5. When the timing duration has reached the target duration but the charging signal has not yet returned to normal, the control module controls the on-board charger to enter a sleep state.

[0127] 6. If the detection module that detected the abnormal signal determines that the detected signal has returned to normal, the control module wakes up the on-board charger so that the on-board charger can resume charging the power battery and the storage battery.
