Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0046] If the power battery on the vehicle maintains a high SOC (State Of Charge) for a long time, the side reactions of the power battery will intensify, the power battery degradation rate will accelerate, affecting the life of the power battery, and further affecting the vehicle's power and range.

[0047] Based on the above problems, the present application provides a method for adjusting the upper limit of battery charging. Figure 1 As shown, the battery charging upper limit adjustment method includes steps S101 to S103.

[0048] Step S101, after the vehicle battery is charged, the current charging upper limit value of the battery, the battery charge amount, the battery power usage and the battery flag are obtained.

[0049] Specifically, the current upper limit value of the battery charge is stored data. After the vehicle battery charge is completed, the current upper limit value of the battery charge can be obtained from a storage device on the vehicle.

[0050] Before charging the vehicle battery, a first remaining power before the battery can be obtained. After the vehicle battery is charged, a second remaining power after the battery is charged can be obtained, and then the difference between the second remaining power and the first remaining power can be calculated to obtain the charge capacity of the battery.

[0051] During the use of the vehicle, the operating voltage and current of the battery can be obtained in real time, and then the battery power can be obtained based on the operating voltage and current of the battery. The obtained battery power is the battery power from the last battery charging to the beginning of the current battery charging.

[0052] The battery flag is stored data, and the battery flag can represent the state of the battery charging upper limit adjustment. After the vehicle battery is charged, the battery flag can be obtained from the storage device on the vehicle.

[0053] Step S102, if the current charging upper limit value is greater than or equal to the first preset limit value, the charging amount is less than the preset charging amount, the used power is less than the preset power and the battery flag is the first flag, the cumulative number of times is increased by a preset value.

[0054] Specifically, if the current upper limit of the battery charge is greater than or equal to the first preset limit, it indicates that the current upper limit of the battery charge is high. If the battery charge is less than the preset charge, it indicates that the battery charge is low, reflecting a low battery usage rate. If the battery power usage is less than the preset power, it indicates that the battery power usage is low, which also reflects a low battery usage rate. If the battery flag is the first flag, it indicates that the user has not modified the battery charge upper limit.

[0055] When the current charging upper limit is greater than or equal to the first preset limit, the charging amount is less than the preset charging amount, the used power is less than the preset power and the battery flag is the first flag, it means that the battery's charging upper limit is high and the usage rate is low. At this time, the cumulative number of times increases by the preset value, that is, counting is performed.

[0056] It should be noted that designers can set the first preset limit, preset charge amount and preset power according to actual conditions. For example, the first preset limit can be set to 90%, 95%, 98% or other values, the preset charge amount can be set to 20%, 30%, 35% or other values, and the preset power can be set to the maximum available power when the remaining battery power is 80% at any temperature, the maximum available power when the remaining battery power is 70% at any temperature, the maximum available power when the remaining battery power is 85% at any temperature, etc.

[0057] The designer can set the preset value according to the actual situation, for example, the preset value can be set to 1, 2, 3 or other values. When the preset value is 1, when the current charging upper limit value is greater than or equal to the first preset limit value, the charging amount is less than the preset charging amount, the used power is less than the preset power, and the battery flag is the first flag, the cumulative number of times increases by 1. When the preset value is 2, when the current charging upper limit value is greater than or equal to the first preset limit value, the charging amount is less than the preset charging amount, the used power is less than the preset power, and the battery flag is the first flag, the cumulative number of times increases by 2.

[0058] Step S103: If the accumulated number of times reaches a preset number of times, a prompt message is sent to remind the user to lower the upper limit of the charging.

[0059] Specifically, if the cumulative number of times reaches the preset number of times, it means that the battery has been in a situation where the upper limit of charging is high but the power usage is low for a long time. At this time, a prompt message is sent to remind the user to lower the upper limit of charging. The prompt message reminds the user that the upper limit of charging of the battery is high but the power usage is low, and reminds the user to reduce the upper limit of charging of the battery. After receiving the prompt message, the user can reduce the upper limit of charging of the battery. In this way, under the premise of meeting the power requirements of the user, the battery can be prevented from maintaining a high SOC for a long time, the attenuation rate of the battery can be slowed down, the service life of the battery can be extended, and the probability of thermal runaway of the battery can be reduced, thereby improving the safety of the vehicle.

[0060] In some embodiments, step S104 may be further included after step S103.

[0061] Step S104: if permission information indicating that the user agrees to lower the upper limit of charging is received, the current upper limit of charging is adjusted to a preset upper limit of charging, and the battery flag is changed to a second flag.

[0062] Specifically, in step S103, when the cumulative number of times reaches the preset number of times, a prompt message is sent, and the prompt message can be displayed on the display device on the vehicle, for example, "The battery power usage is low and the charging upper limit is high, do you agree to lower the charging upper limit" can be displayed on the display device. After receiving the prompt message, the user can choose to agree to send the permission message by operating the display device. After receiving the permission message used to indicate that the user agrees to lower the charging upper limit, the current charging upper limit is adjusted to the preset charging upper limit. The preset charging upper limit is less than the current charging upper limit of the battery, that is, the current charging upper limit of the battery is automatically lowered to prevent the battery from maintaining a high SOC for a long time, slow down the battery attenuation rate, and extend the battery life.

[0063] After the current charging upper limit is adjusted to the preset charging upper limit, the battery flag is changed to the second flag. When the battery flag is subsequently identified as the second flag, it can be known that the battery charging upper limit has been adjusted.

[0064] It should be noted that the preset upper limit value of charging can be a fixed value, and the designer can set the specific value of the preset upper limit value of charging according to the actual situation, for example, the preset upper limit value of charging can be set to 80%, 75%, 70% or other values. The preset upper limit value of charging can also be a non-fixed value, for example, the specific preset upper limit value of charging can be determined according to the state parameters and usage parameters of the battery.

[0065] In some embodiments, Figure 2 As shown, step S103 may further include steps S105 to S107.

[0066] Step S105 : after receiving permission information indicating that the user agrees to lower the upper limit of charging, a plurality of recommended upper limits of charging are sent.

[0067] Specifically, in step S103, when the cumulative number of times reaches the preset number of times, a prompt message is sent, and the prompt message can be displayed on the display device on the vehicle. For example, the display device can display "the battery power is low and the charging upper limit is high, do you agree to lower the charging upper limit?" After receiving the prompt message, the user can choose to agree to send the permission message by operating the display device. After receiving the permission message indicating that the user agrees to lower the charging upper limit, multiple recommended charging upper limits are sent, and the multiple recommended charging upper limits can be displayed on the display device on the vehicle for the user to choose.

[0068] It should be noted that all recommended upper limit values ​​are lower than the current upper limit value, and the user can choose the lower upper limit value. The multiple recommended upper limit values ​​sent can be set by the designer according to the actual situation. For example, the multiple recommended upper limit values ​​can be set to 80%, 70%, 60%, 50% or other values.

[0069] Step S106: If a selection signal is received, a target charging upper limit value selected by the user is determined from a plurality of recommended charging upper limits according to the selection signal.

[0070] Specifically, the user makes a selection by operating the display device on the vehicle, and the selection device sends a corresponding selection signal according to the user's operation. After receiving the selection signal, the target charging upper limit value selected by the user is determined from multiple recommended charging upper limits according to the selection signal.

[0071] Step S107, adjusting the current charging upper limit value to the target charging upper limit value, and changing the battery flag bit to the second flag bit.

[0072] Specifically, after the target charging upper limit value is determined, the current charging upper limit value is adjusted to the target charging upper limit value, that is, the current charging upper limit value of the battery is lowered, so as to avoid the battery maintaining a high SOC for a long time, slow down the battery attenuation rate, and delay the battery service life.

[0073] After the current charging upper limit is adjusted to the preset charging upper limit, the battery flag is changed to the second flag. When the battery flag is subsequently identified as the second flag, it can be known that the battery charging upper limit has been adjusted.

[0074] In some embodiments, the step S103 may further include: if prohibition information indicating that the user does not agree to reduce the upper limit of charging value is received, maintaining the current upper limit of charging value and the battery flag bit unchanged.

[0075] Specifically, after receiving the prompt message, the user may choose not to agree to reduce the upper limit of the battery charge value according to his own needs. At this time, the user can send a prohibition message indicating that the user does not agree to reduce the upper limit of the charge value by operating the device on the vehicle. If the prohibition message indicating that the user does not agree to reduce the upper limit of the charge value is received, the current upper limit of the charge value and the battery flag bit are maintained unchanged.

[0076] In some embodiments, the battery charging upper limit adjustment method also includes: if the charging amount is greater than or equal to the preset charging amount, the used power is greater than or equal to the preset power, the current charging upper limit is less than the first preset limit, or the battery flag is a flag other than the first flag, the cumulative number of times is set to zero.

[0077] Specifically, if the charge capacity is greater than or equal to the preset charge capacity, it means that the charge capacity of the battery is large and the battery usage rate is high. If the power usage is greater than or equal to the preset power, it means that the power usage of the battery is large. If the current upper limit value of the charge is less than the first preset limit value, it means that the current upper limit value of the charge of the battery is small. If the battery flag is a flag other than the first flag, it means that the upper limit value of the charge of the battery has been adjusted.

[0078] When the charge amount is greater than or equal to the preset charge amount, the power used is greater than or equal to the preset power, the current charge upper limit is less than the first preset limit, or the battery flag is a flag other than the first flag, it means that the battery charge upper limit does not need to be lowered, and the cumulative number is set to zero. After the cumulative number is set to zero, the cumulative number is counted again.

[0079] In some embodiments, Figure 3 As shown, the battery charging upper limit adjustment method further includes steps S201 to S203.

[0080] Step S201, before charging the battery of the vehicle, obtaining the accumulated throughput of the battery.

[0081] Specifically, the cumulative throughput of the battery refers to the total energy accumulated in or out of the battery in multiple charge and discharge cycles. Before charging the battery of each vehicle, the cumulative throughput of the battery is obtained. The cumulative throughput is the cumulative throughput when the flag bit of the battery is the second flag bit, that is, the cumulative throughput of the battery after the charging upper limit value is reduced.

[0082] Step S202: if the battery flag is the second flag, the current charging upper limit is less than or equal to the second preset limit, and the accumulated throughput is greater than or equal to the preset throughput, the current charging upper limit is stored.

[0083] Step S203, after the current charging upper limit value is stored, the current charging upper limit value is adjusted to 100%, and the battery flag is changed to the third flag.

[0084] Specifically, if the battery flag is the second flag, it means that the current upper limit value of the battery is a lowered upper limit value. If the current upper limit value of the battery is less than or equal to the second preset limit value, it means that the current upper limit value of the battery is in a relatively small state. If the accumulated throughput is greater than or equal to the preset throughput, it means that the battery has a long service life.

[0085] If the battery flag is the second flag, the current charging upper limit is less than or equal to the second preset limit, and the cumulative throughput is greater than or equal to the preset throughput, it means that the battery has been in an uncharged state for a long time. In order to improve the accuracy of the battery SOC, it is necessary to calibrate the SOC of the battery in a fully charged state, so the current charging upper limit of the battery is adjusted to 100%. When the current charging upper limit of the battery is adjusted to 100%, the battery can be fully charged when it is charged. When the battery is fully charged, the SOC can be calibrated, thereby realizing the SOC calibration of the battery in a fully charged state and improving the accuracy of the battery SOC.

[0086] Before adjusting the current charging upper limit value to 100%, the current charging upper limit value needs to be stored so that the current charging upper limit value of the battery can be restored to the stored charging upper limit value later, so that the battery meets the current usage requirements of the user.

[0087] It should be noted that the designer can set the specific values ​​of the second preset limit and the preset throughput according to the actual situation. For example, the second preset limit can be set to 75%, 80%, 85% or other values. The preset throughput can be set to 5*C0, 6*C0, 7*C0 or other values, where C0 is the rated capacity of the battery.

[0088] In some embodiments, the battery charging upper limit adjustment method further includes: before charging the battery of the vehicle, if the battery flag is identified as the third flag, adjusting the current charging upper limit to the stored charging upper limit.

[0089] Specifically, before charging the vehicle battery, if the battery flag is identified as the third flag, it means that the battery's upper limit value was adjusted to 100% during the last charging, that is, the battery was fully charged and the SOC calibration was completed. At this time, the current upper limit value is adjusted to the stored upper limit value, so that the current upper limit value of the battery meets the current power demand of the user.

[0090] In order to clearly illustrate the working principle of the battery charging upper limit adjustment method of the present application, a specific example is given below for illustration.

[0091] Before charging the vehicle's battery, if it is identified that the battery flag is the second flag (the battery flag is 1), the current charging upper limit is less than or equal to 80%, and the cumulative throughput is greater than or equal to 5*C0 (C0 is the rated capacity of the battery), the current charging upper limit is stored. After the current charging upper limit is stored, the current charging upper limit is adjusted to 100%, and the battery flag is changed to the third flag (the battery flag is 2). When the current charging upper limit of the battery is adjusted to 100%, the battery can be fully charged when it is charged. When the battery is fully charged, the SOC can be calibrated, thereby achieving SOC calibration of the battery in a fully charged state and improving the accuracy of the battery SOC.

[0092] If the battery flag is identified as the third flag (battery flag is 2) before charging the vehicle's battery, it means that the battery's upper limit value was adjusted to 100% during the last charging, that is, the battery was fully charged and SOC calibration was completed last time. At this time, the current upper limit value is adjusted to the stored upper limit value, so that the current upper limit value of the battery meets the user's current power demand.

[0093] After the vehicle battery is charged, if it is identified that the current charging upper limit is greater than or equal to 90%, the charging amount is less than 30%, the power used is less than the preset power, and the battery flag is the first flag (the battery flag is 0), the cumulative number of times will be increased by the preset value. If the cumulative number reaches 7 times, a prompt message is sent to remind the user to lower the charging upper limit. After receiving the prompt message, the user can lower the battery's charging upper limit. In this way, under the premise of meeting the user's power requirements, the battery can be prevented from maintaining a high SOC for a long time, the battery's attenuation rate can be slowed down, the battery's service life can be extended, and the probability of battery thermal runaway can be reduced, thereby improving the safety of the vehicle.

[0094] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
