[0002] With the development of electrification of new energy vehicles, the number of vehicle electrical components is increasing day by day. As a low-voltage energy source, low-voltage batteries (referred to as batteries) are particularly important. When the state of charge (SOC) of the battery is low, it is necessary to control the high-voltage relay (referred to as relay) to close, and then recharge the battery. If it is determined that the battery recharge conditions are met according to the current state of the battery, the relay needs to be controlled to close to recharge the battery. After the battery recharge is completed, the control relay is disconnected. However, when the battery is recharged, there may be other high-voltage scheduled charging requests on the vehicle, such as scheduled charging, scheduled air conditioning, and scheduled refrigerators. If after the relay is disconnected, a short interval of, for example, but not limited to, half an hour has arrived at the time when the scheduled charging set by the user starts, the relay needs to be controlled to close again to charge the vehicle's power battery.

[0042] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0044] Figure 2 A schematic diagram of the structure of a vehicle battery charging system provided by an embodiment of the present disclosure;

[0045] Figure 3 A schematic structural diagram of a vehicle battery charging device provided in an embodiment of the present disclosure. DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0048] The vehicle battery charging method provided by the embodiment of the present disclosure obtains the working parameters of the battery at the current moment, and when judging that the working parameters meet the first battery charging condition and determining that the vehicle scheduled charging request is received, judges the difference between the current moment and the vehicle scheduled charging moment, and when judging that the current moment is close to the vehicle scheduled charging moment, generates a delayed charging request instruction, and does not immediately charge the battery. When the vehicle scheduled charging moment is reached, the battery can be charged while the vehicle power battery is being charged, which can reduce the closing and opening operations of the relay, which is conducive to extending the life of the relay.

[0049] In conjunction with the accompanying drawings, the vehicle battery charging method, device, medium, equipment, system and vehicle provided in the embodiments of the present disclosure are exemplarily described below.

[0050] Figure 1 A schematic diagram of a vehicle battery charging method provided in an embodiment of the present disclosure. Figure 2 A schematic diagram of the structure of a vehicle battery charging system provided in an embodiment of the present disclosure. Figure 1 The method shown is applied to Figure 2 The vehicle battery charging system shown in the figure. Figure 1 As shown, the vehicle battery charging method includes the following steps:

[0051] S101, obtaining the current working parameters of the battery.

[0052] Specifically, Figure 2The structure diagram of a vehicle battery charging method provided by the embodiment of the present disclosure is as follows. Figure 2 As shown, the vehicle battery charging system 20 includes a relay 21, a vehicle power battery 22 and a battery 23. When the relay 21 is closed, the charging circuit to the battery 23 can be connected, thereby realizing charging to the battery 23.

[0053] In this step, the current working parameters of the battery 23 are obtained, for example, the current voltage and charge state of the battery 23 are obtained, and the first battery recharging condition is determined based on the current working parameters of the battery 23 to determine whether to trigger the first battery recharging condition, so as to execute subsequent steps based on the determination result.

[0054] S102: If the operating parameters meet the first battery charging condition, determine whether a vehicle scheduled charging request is received, where the vehicle scheduled charging request is a request to charge the vehicle power battery.

[0055] Specifically, based on the working parameters of the battery at the current moment obtained in S101, and according to the working parameters of the battery at the current moment, it is determined whether the first battery charging condition is triggered. When it is determined that the working parameters meet the first battery charging condition, it is determined whether there is a vehicle reservation charging request set by the user, so as to execute subsequent steps according to the judgment result.

[0056] Among them, the vehicle scheduled charging request is a request for vehicle scheduled charging set by the user. When the time for the vehicle scheduled charging set by the user is reached, the vehicle power battery can be charged, thereby realizing intelligent control of the power battery charging, which is conducive to improving the user experience.

[0057] In some embodiments, the operating parameters include the voltage and state of charge of the battery; the operating parameters satisfying the first power replenishment condition include:

[0058] The voltage is less than a first voltage threshold and greater than or equal to a second voltage threshold, and the state of charge is less than a first state of charge threshold and greater than or equal to a second state of charge threshold.

[0059] Therefore, based on the comparison relationship between the battery voltage and the first voltage threshold and the second voltage threshold, and based on the comparison relationship between the battery state of charge and the first state of charge threshold and the second state of charge threshold, it is determined whether the battery is in a state requiring recharge.

[0060] Among them, the first voltage threshold and the second voltage threshold can be set according to the requirements of the vehicle battery charging method provided by the embodiment of the present disclosure, and the first state of charge threshold and the second state of charge threshold can also be set according to the requirements of the vehicle battery charging method provided by the embodiment of the present disclosure, and no specific limitation is made here.

[0061] In some embodiments, the vehicle battery charging method further includes:

[0062] If the voltage is less than the second voltage threshold and / or the state of charge is less than the second state of charge threshold, it is determined that the operating parameters meet the second battery charging condition, and a battery charging request instruction is generated.

[0063] Among them, the recharge request instruction indicates to recharge the battery at the current moment. Specifically, when it is determined that the battery voltage is less than the second voltage threshold, or the battery state of charge is less than the second state of charge threshold, or the battery voltage is less than the second voltage threshold and the battery state of charge is less than the second state of charge threshold, it can be judged that the battery power is too low. In order to prevent the problem that the low battery power triggers the low voltage protection disconnection and causes the vehicle to be unable to drive, a recharge request instruction is generated at this time. Based on the recharge request instruction, control Figure 2 The relay 21 in the circuit is closed, which can conduct the power supply circuit to the battery 23, thereby supplying power to the battery 23.

[0064] S103: Determine that a vehicle charging reservation request is received, and obtain a first time difference between the current time and the vehicle charging reservation time.

[0065] Specifically, in this step, if there is a vehicle scheduled charging request set by the user, it is determined that the vehicle scheduled charging request is received. When it is determined that the vehicle scheduled charging request is received, a first time difference between the current time and the vehicle scheduled charging time is obtained.

[0066] S104: Determine that the first time difference is less than or equal to a first time threshold, and generate a delayed power replenishment request instruction.

[0067] The delayed charging request instruction indicates that the battery will not be charged at the current time, and the battery will be charged at the scheduled charging time of the vehicle. Figure 2 When the relay 21 is closed, the vehicle power battery 22 can be charged while the storage battery 23 is supplemented, which can reduce the closing and opening operations of the relay 21 and is beneficial to prolonging the life of the relay 21.

[0068] Based on this, a first time threshold is set, and when it is determined that the first time difference is less than or equal to the first time threshold, a delayed power replenishment request instruction is generated.

[0069] Specifically, when it is determined that the current time is close to the scheduled charging time of the vehicle, the battery is not immediately charged. When the scheduled charging request time set by the user is reached, the control Figure 2 The relay 21 in the circuit is closed, and the storage battery 23 can be supplemented with electricity while charging the vehicle power battery 22.

[0070] In combination with the background technology, if it is determined that the conditions for battery recharging are met, the relay needs to be controlled to close to recharge the battery. If the time for the scheduled charging request has not arrived after the battery recharging is completed, the relay needs to be disconnected. After the relay is disconnected, if the time for the scheduled charging request arrives within a short interval, such as but not limited to half an hour, such as the time for the scheduled charging start of the vehicle set by the user, the relay needs to be controlled to close again to charge the vehicle's power battery. The above-mentioned frequent closing and disconnecting of the relay reduces the life of the relay.

[0071] In addition, in the above-mentioned process of replenishing the battery, if the time of the scheduled charging request is reached, such as the time set by the user to start the scheduled charging of the vehicle, if the ambient temperature is low at this time, the relay needs to be disconnected, and the power battery needs to be preheated using power supply equipment such as a charging pile. After the power battery is preheated, the relay needs to be closed again to charge the power battery of the vehicle. There is also the operation of frequently closing and disconnecting the relay, which reduces the life of the relay.

[0072] The embodiment of the present disclosure determines the difference between the current time and the scheduled charging time of the vehicle, and generates a delayed charging request instruction when it is determined that the current time is close to the scheduled charging time of the vehicle, and does not immediately charge the battery. When the scheduled charging time of the vehicle is reached, the battery can be charged while the power battery is charged, which can reduce the closing and opening operations of the relay, which is conducive to extending the life of the relay.

[0073] In addition, when it is determined that the current time is close to the scheduled charging time of the vehicle, a delayed charging request instruction is generated at this time, and the battery is not immediately charged, and the relay is in a disconnected state. If the ambient temperature is detected to be low, the power battery can be preheated in advance with the relay in a disconnected state. After the power battery is preheated, when the vehicle's scheduled charging time arrives, the power battery can be charged by controlling the relay to close, which can reduce the frequent closing and disconnecting operations of the relay caused by the need to preheat the power battery, which is beneficial to extending the life of the relay.

[0074] In some embodiments, the vehicle battery charging method further includes:

[0075] It is determined that the first time difference is greater than the first time threshold, or it is determined that the vehicle charging reservation request is not received, and a charging request instruction is generated.

[0076] The charging request instruction indicates that the battery is charged at the current time. Specifically, in combination with the above, when it is determined that the current time is long apart from the scheduled charging time of the vehicle, that is, it is determined that the first time difference is greater than the first time threshold, in order to prevent the vehicle from being delayed for a long time due to the low power of the battery affecting the driving of the vehicle, the charging request instruction is generated at this time, and then the relay is controlled to close to charge the battery based on the charging request instruction.

[0077] Alternatively, when the user does not set a vehicle scheduled charging request, that is, when it is determined that the vehicle scheduled charging request has not been received, a charging request instruction is also generated, and then the relay is controlled to close to charge the battery based on the charging request instruction.

[0078] The vehicle battery charging method provided by the embodiment of the present disclosure obtains the working parameters of the battery at the current moment, determines whether the working parameters meet the first charging condition of the battery; determines whether the working parameters meet the first charging condition of the battery, determines whether a vehicle scheduled charging request is received, and the vehicle scheduled charging request is a request to charge the power battery; determines that the vehicle scheduled charging request is received, obtains the first time difference between the current moment and the vehicle scheduled charging moment; determines that the first time difference is less than or equal to the first time threshold, and generates a delayed charging request instruction; determines that the vehicle scheduled charging moment has arrived, and controls the relay to close to charge the battery. Thus, by obtaining the working parameters of the battery at the current moment, when it is determined that the working parameters meet the first charging condition of the battery, and when it is determined that the vehicle scheduled charging request has been received, the difference between the current moment and the vehicle scheduled charging moment is judged, and when it is determined that the current moment is close to the vehicle scheduled charging moment, a delayed charging request instruction is generated, and the battery is not immediately charged. When the vehicle scheduled charging moment arrives, the battery can be charged while the power battery is charged, which can reduce the closing and disconnecting operations of the relay, which is conducive to extending the life of the relay. In addition, when it is determined that the current time is close to the scheduled charging time of the vehicle, a delayed charging request instruction is generated at this time, and the battery is not immediately charged, and the relay is in a disconnected state. If the ambient temperature is detected to be low, the power battery can be preheated in advance with the relay in a disconnected state. After the power battery is preheated, when the vehicle's scheduled charging time arrives, the power battery can be charged by controlling the relay to close, which can reduce the frequent closing and disconnecting operations of the relay caused by the need to preheat the power battery, which is beneficial to extending the life of the relay.

[0079] In some embodiments, the vehicle battery charging method further includes:

[0080] In response to a signal indicating that battery charging is complete, determining whether a request for scheduled start of a vehicle electrical device is received, wherein the vehicle electrical device includes a refrigerator and / or an air conditioner;

[0081] Determine that a request for scheduled activation of the vehicle electrical equipment is received, and obtain a second time difference between the battery charging completion time and the vehicle electrical equipment scheduled activation time;

[0082] It is determined that the second time difference is less than or equal to the second time threshold, and a continue power replenishment request instruction is generated, where the continue power replenishment request instruction indicates that the relay is continued to be controlled to be closed when the battery power replenishment is completed.

[0083] Specifically, after the battery charging is completed, it is determined whether there is a user-set vehicle electrical equipment scheduled start request. The vehicle electrical equipment may be a refrigerator and / or an air conditioner. When it is determined that there is a user-set vehicle electrical equipment scheduled start request, the time difference between the battery charging completion time and the vehicle electrical equipment scheduled start time is obtained to determine whether the battery charging completion time is close to the vehicle electrical equipment scheduled start time. If it is determined that the battery charging completion time is close to the vehicle electrical equipment scheduled start time, the relay is kept closed at this time, and then the vehicle electrical equipment is powered when the vehicle electrical equipment scheduled start time is reached.

[0084] Based on this, a second time threshold is set, and when it is determined that the second time difference is less than or equal to the second time threshold, a continuous power replenishment request instruction is generated, and the relay is controlled to close based on the continuous power replenishment request instruction. Figure 2 The relay 21 in the figure is electrically connected (not shown), and when the relay 21 is closed, it can directly supply power to the vehicle's electrical equipment.

[0085] Therefore, when the battery recharging is completed, it is determined whether there is a scheduled refrigerator or air conditioner to start working within the next period of time. If yes, the battery recharging request instruction will continue to be sent until the refrigerator or air conditioner starts working. This can avoid the relay being disconnected after the recharging is completed, and then the refrigerator or air conditioner starts working and requests high voltage again, and the relay is re-closed. This can reduce the number of times the relay is opened and closed, which is beneficial to extending the life of the relay and saving the energy consumption of the vehicle's power battery.

[0086] In some embodiments, the vehicle battery charging method further includes:

[0087] It is determined that the second time difference is greater than the second time threshold, or it is determined that no reservation start request for the vehicle electrical equipment is received, and a charging completion instruction is generated.

[0088] Specifically, in combination with the above, when it is determined that the battery charging completion time is significantly different from the scheduled start-up time of the vehicle electrical equipment, that is, it is determined that the second time difference is greater than the second time threshold, a charging completion instruction is generated, and the relay is controlled to be disconnected based on the charging completion instruction, which is beneficial to saving energy consumption.

[0089] Alternatively, when the user has not set a vehicle electrical equipment scheduled start request, that is, when it is determined that the vehicle electrical equipment scheduled start request has not been received, after the battery is fully charged, a charging completion instruction is generated, and the relay is controlled to be disconnected based on the charging completion instruction.

[0090] In some embodiments, before obtaining the current working parameters of the battery, the vehicle battery charging method further includes:

[0091] A wake-up command is issued at a preset time interval, and the wake-up command is used to wake up the working parameter collection device to collect the working parameters of the battery.

[0092] Specifically, Figure 2 As shown, it can be Figure 2 The controller 25 in the apparatus periodically sends a wake-up instruction to the working parameter acquisition device 24 to wake up the working parameter acquisition device 24 to work, and collects the working parameters of the battery 23 through the working parameter acquisition device 24. The working parameter acquisition device 24 transmits the collected working parameters of the battery 23 to the controller 25, and the controller 25 determines whether the working parameters of the battery 23 meet the first power replenishment condition. The specific first power replenishment condition can be found above and will not be repeated here.

[0093] The vehicle battery charging method provided by the embodiment of the present disclosure obtains the working parameters of the battery at the current moment, and when judging that the working parameters meet the first battery charging condition, and determining that the vehicle scheduled charging request is received, the difference between the current moment and the vehicle scheduled charging moment is judged, and when judging that the current moment is close to the vehicle scheduled charging moment, a delayed charging request instruction is generated, and the battery is not immediately charged. When the vehicle scheduled charging moment is reached, the battery can be charged while the power battery is charged, which can reduce the closing and disconnecting operations of the relay, which is beneficial to prolonging the life of the relay. In addition, when the battery charging is completed, it is judged whether there is a scheduled vehicle electrical equipment such as a refrigerator or air conditioner to start working in the next period of time. If there is, the battery charging request instruction continues to be issued until the refrigerator or air conditioner starts working, which can avoid the lower relay being disconnected after the charging is completed, and then the refrigerator or air conditioner starts working again to request the upper high voltage, and the relay is closed again, which can reduce the number of disconnections and closures of the relay, which is beneficial to prolonging the life of the relay and saving the energy consumption of the vehicle's power battery.

[0094] The present disclosure also provides a vehicle battery charging system. Figure 2As shown, the vehicle battery charging system 20 includes: a relay 21, a battery 23, a working parameter acquisition device 24 and a controller 25; the controller 25 is respectively communicated with the working parameter acquisition device 24 and the relay 21, and the working parameter acquisition device 24 is electrically connected to the battery 23; the controller 25 is used to execute the steps of the vehicle battery charging method as described in the above embodiment.

[0095] Specifically, the controller 25 is used to obtain the working parameters of the battery 23 at the current moment through the working parameter acquisition device 24, and determine whether the working parameters meet the first battery replenishment condition; determine whether the working parameters meet the first battery replenishment condition, determine whether a vehicle scheduled charging request is received, and the vehicle scheduled charging request is a request to charge the power battery; determine that the vehicle scheduled charging request is received, obtain the first time difference between the current moment and the vehicle scheduled charging moment; determine that the first time difference is less than or equal to the first time threshold, and generate a delayed charging request instruction; in response to reaching the vehicle scheduled charging moment, control the relay 21 to close and replenish the battery 23. Therefore, it has the same or similar beneficial effects, which are not repeated here.

[0096] In some embodiments, Figure 2 As shown, the vehicle battery charging system 20 also includes: an on-board charger 27, a voltage converter 26, a vehicle power battery 22 and a battery management system 28; the on-board charger 27, the relay 21 and the vehicle power battery 22 are electrically connected in sequence, and the relay 21, the voltage converter 26, the battery 23 and the working parameter acquisition device 24 are electrically connected in sequence; the controller 25 is communicated with the relay 21 through the battery management system 28, and the controller 25 is also communicated with the voltage converter 26 and the on-board charger 27.

[0097] The battery management system 28 is used to obtain the relay 21 closing instruction issued by the controller 25, so as to control the closing and opening states of the relay 21.
