[0047] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of this specification. On the contrary, they are merely examples of devices and methods consistent with some aspects of one or more embodiments of this specification as detailed in the appended claims.
[0048] It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily executed in the order shown and described in this specification. In some other embodiments, the steps included in the method may be more or less than those described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; and multiple steps described in this specification may also be combined into a single step for description in other embodiments.
[0049] To solve the technical problem in the above related technologies that when the user actually charges the lithium iron phosphate battery system of the vehicle, the battery system may not be fully charged, resulting in inaccurate display of the charged power of the lithium iron phosphate battery system, the embodiment of the present application provides a charging method. When a reminder generated by the battery system of the vehicle not being fully charged multiple times is obtained, at this time, the vehicle is started and run by the user. The real-time available power of the vehicle is discounted to obtain the discounted power, thereby reducing the real-time available power to control the operation of the vehicle. Subsequently, when the running vehicle stops for vehicle charging, the battery system is forced to be fully charged. In this way, when the battery system is charging, the user is forced to fully charge to ensure accurate display of the charged power of the lithium iron phosphate battery system.
[0050] Figure 1 The system structure diagram of the charging method provided by the embodiment of the present application is shown.
[0051] As Figure 1 shown, the charging method of the present application can be applied to a charging reminder system. The charging reminder system can but is not limited to include a battery BMS (Battery Management System), and a charging device, a T-BOX (Telematics Box), a current sensor, and an electronic device that are respectively connected to the battery BMS.
[0052] Among them, the charging device is used to charge the battery system. This charging device can but is not limited to include one or more of a fast charging pile and an on-vehicle charger. The on-vehicle charger refers to a device installed inside an electric vehicle that converts AC (Alternating Current) provided by an external power source into DC (Direct Current) for charging the battery of the electric vehicle. The charging pile is a device installed in public places or private locations that provides an external power source for an electric vehicle to supply power for the vehicle to charge.
[0053] The battery BMS is used to manage the charging and discharging of the battery system, monitor the battery status, ensure the safe and stable operation of the battery, and extend the service life of the battery. In this solution, with the battery BMS as the center, it collects the real-time charging current value of the vehicle collected by the current sensor, and obtains the time point sent by the T-BOX, such as Beijing time. After comprehensive judgment by the battery BMS, when the battery BMS determines that the battery system is not fully charged and meets the reminder condition, it sends a reminder (also called a full charge reminder) for reminding the vehicle to be fully charged to the T-BOX, and the T-BOX then pushes it to the product application APP (Application) of the mobile terminal. If the reminder exit condition is still not met after a period of time after the reminder, the battery BMS restricts the available power in the low SOC section to avoid vehicle breakdown and affect the driving experience, and forces the user to fully charge to correct the SOC.
[0054] It should be noted that the above-mentioned electronic devices may include, but are not limited to, in-vehicle terminals connected to vehicles and mobile terminals independent of vehicles, etc. These in-vehicle terminals with information processing functions may include, but are not limited to, body processors, controllers, center consoles, and battery BMSs. The vehicle display devices used to display information in the vehicle-mounted devices may include, but are not limited to, vehicle-mounted screens (also known as large screens, such as center control screens and automotive HUD head-up displays). The mobile terminals independent of vehicles may include, but are not limited to, smart phones, smart phone watches, tablets, or laptop computers. For the above-mentioned electronic devices, the device that is closer to the user or more convenient to use can be selected, and the charging method of the embodiments of the present application can be executed on that device.
[0055] When the execution subject of this solution is an electronic device independent of or separated from a vehicle, it needs to cooperate with a device with processing functions to complete. For example, as Figure 1 shown, the battery BMS sends a reminder to the vehicle-mounted screen to remind that the vehicle is fully charged, and the vehicle-mounted screen displays the reminder information. If the reminder exit condition is still not met after a period of time after the reminder, the vehicle-mounted screen automatically modifies the charging SOC (State of Charge, the charging state of the battery, usually expressed as the percentage of the remaining battery power) upper limit to 100% (also known as the upper limit for forced charging is full charge), and sends it back to the battery BMS. During charging, the power is automatically charged to 100% to correct the SOC. For detailed description, please refer to the following text.
[0056] Figure 2 The following shows a schematic flowchart of the charging method provided by the embodiments of the present application.
[0057] As Figure 2 shown, the charging method may include, but is not limited to, the following steps 110 and 140:
[0058] Step 110, if a reminder to remind that the vehicle is fully charged is obtained and it is detected that the vehicle is running, then discount the real-time available power of the vehicle to obtain the discounted power; the reminder is generated when it is detected that the battery system of the vehicle has not been fully charged multiple times.
[0059] Among them, the above-mentioned reminder to remind that the vehicle is fully charged (also known as full charge reminder) is determined in the following way: if it is detected that the battery system of the vehicle is not fully charged, then generate and indicate a reminder to remind that the vehicle is fully charged. This article can achieve forced reminder, and non-users can cancel it manually. In this way, the effect of forced full charge can be improved.
[0060] Furthermore, the above-mentioned charging method may further include, but is not limited to, adopting any of the following methods to determine that the battery system has not been fully charged multiple times to meet the reminder condition for the vehicle to be fully charged:
[0061] In an alternative manner, it is determined that the cumulative number of charging times when the battery system fails to be fully charged multiple times reaches a second preset cumulative number. The "second" in the "second preset cumulative number" and the "first" in the "first preset cumulative number" in this article are both used to distinguish two different preset cumulative numbers. The second preset cumulative number is the value corresponding to the reminder condition when the cumulative number of charging times when the battery system fails to be fully charged multiple times reaches a certain level. The first preset cumulative number is the value corresponding to the discount condition when the cumulative number of discharging times when the battery system discharges multiple times reaches a certain level.
[0062] In a second alternative manner, it is determined that the cumulative charging capacity when the battery system fails to be fully charged multiple times exceeds the healthy charging capacity of the battery system during multiple charging processes.
[0063] The above-mentioned reminder indication methods can be, but are not limited to, one or more of sound reminders and visual reminders. Among them, the specific way of visual reminder: display text or icon prompts on the dashboard, HUD (Head-Up Display), central control screen, rearview mirror, etc. For example, "To keep the power battery in the best health condition, it is recommended to fully charge at least once a week." In this way, the visual reminder provides clear and intuitive information and can quickly attract the driver's attention when needed. The HUD allows the driver to directly see the screen without having to look down, improving driving safety.
[0064] The above-mentioned reminder methods can be continuous reminders or intermittent regular reminders, which are not limited here.
[0065] Next, in step 110 above, the real-time available power of the vehicle can be discounted according to the discount factor to obtain the discounted power. The discount factor can be a preset fixed value or a value that changes with the SOC and / or discharge capacity or charging capacity.
[0066] Step 120, control the vehicle to run according to the discounted power; the discounted power is less than the real-time available power.
[0067] The real-time available power of the vehicle in this article refers to the actual power that the vehicle's power system (such as an engine or a motor) can provide at each moment. Specifically, the real-time available power can be the power that can be provided according to actual factors such as the current working state, load, speed, and road conditions at the current moment. It reflects the current power output ability of the vehicle and is closely related to the maximum power of the engine or motor and other real-time factors (such as fuel consumption, battery power, etc.).
[0068] The vehicle operation in this article is used to represent that after the vehicle is powered on and started, it travels. The greater the power of the vehicle operation, the higher the speed at which the vehicle can travel. Especially when going uphill or accelerating, the required power increases.
[0069] After the above step 120, if the running vehicle stops and it is detected that the vehicle is being charged, the battery system is forced to be fully charged. The details are as follows.
[0070] Step 130, if the running vehicle stops and it is detected that the vehicle is being charged, the battery system is forced to be fully charged.
[0071] The above situation where the running vehicle stops and it is detected that the vehicle is being charged is also referred to as the running vehicle stopping to charge the battery system. When the user is reminded forcibly multiple times and there is power limitation, as long as the user charges, they are forced to fully charge.
[0072] It should be noted that the above step 130 can be implemented through the following examples: In some examples, if the vehicle display device of the vehicle shows that the vehicle needs to be charged for endurance, then after it is detected that the running vehicle stops and it is detected that the vehicle is being charged, the battery system is forced to be fully charged. In this way, the charging information can be displayed on the vehicle's dashboard to notify the user to charge in a timely manner. For example, the vehicle display device such as the dashboard and the screen.
[0073] In another example, if the vehicle broadcasts a voice for reminding that the vehicle needs to be charged for endurance, then after it is detected that the running vehicle stops and it is detected that the vehicle is being charged, the battery system is forced to be fully charged. Among them, the voice for reminding that the vehicle needs to be charged for endurance is broadcast through the vehicle audio.
[0074] In the related art, in order to ensure the SOC accuracy of the lithium iron phosphate battery, the lithium iron phosphate battery needs to be fully charged once every period of use, and this part of the requirement is often written in the vehicle's instruction manual, but customers often do not read the instruction manual. Therefore, it is necessary to give a reminder on the in-vehicle display interface. If the customer still does not operate according to the instruction manual, there may be a large error in the current vehicle SOC. When driving in the low SOC section, large-current discharge may directly cause the battery to be under-voltage, and ultimately cause the vehicle to break down.
[0075] Compared with the related art, in the embodiment of the present application, a reminder is given on the vehicle display device, that is, a full charge reminder is issued. If the customer still does not operate, the vehicle will limit the vehicle's power usage in the low SOC section to avoid the vehicle breaking down, and try its best to let the customer fully charge once.
[0076] In this regard, the above step 130 can be further implemented through the following steps: When the running vehicle stops to charge the battery system, display the upper limit for forced charging as full charge, so as to charge the battery system according to full charge.
[0077] Continue to refer to Figure 2 As shown, the above step 120 of the present application can be implemented through at least one of the following embodiments:
[0078] In the first optional embodiment, in the first step, based on the real-time remaining power of the vehicle, according to the corresponding relationship between the first discount factor and the remaining power of the vehicle, determine the first discount factor corresponding to the real-time remaining power; the first discount factor is a positive number less than or equal to 1.
[0079] Among them, the above-mentioned corresponding relationship between the first discount factor and the remaining power of the vehicle can be a functional relationship or a tabular corresponding relationship, which is not limited here. As long as it can reflect that the first discount factor increases as the real-time remaining power increases.
[0080] In the second step, according to the corresponding first discount factor, discount the real-time available power of the vehicle to obtain the discounted power.
[0081] Among them, the first discount factor is directly proportional to the real-time remaining power. In this way, the first discount factor increases as the real-time remaining power increases. Of course, the above k1 can be a functional relationship or a tabular corresponding relationship, which is not limited here.
[0082] Exemplary one, the functional relationship of k1 can be represented by the following piecewise function:
[0083]
[0084] Among them, k1 is the first discount factor and SOC is the real-time remaining power.
[0085] Exemplary two, the functional relationship of k1 can be represented by the following piecewise function:
[0086]
[0087] In this way, on the premise of ensuring driving safety, the greater the power, the more obvious the user's driving experience of the vehicle after the power is discounted.
[0088] In the second optional embodiment, in the first step, if it is detected that the real-time discharge situation during the vehicle operation meets the discount condition, then based on the real-time discharge situation, according to the corresponding relationship between the second discount factor and the discharge situation of the vehicle, determine the second discount factor corresponding to the real-time discharge situation; the second discount factor is a positive number less than or equal to 1.
[0089] Among them, the above-mentioned corresponding relationship between the second discount factor and the discharge situation of the vehicle can be a functional relationship or a tabular corresponding relationship, which is not limited here. As long as it can reflect that the second discount factor decreases as the cumulative discharge times of the real-time discharge situation.
[0090] In the second step, according to the corresponding second discount factor, discount the real-time available power of the vehicle to obtain the discounted power.
[0091] Among them, in one embodiment, the second discount factor is inversely proportional to the cumulative number of discharges of the real-time discharge situation. In this way, the second discount factor decreases with the cumulative number of discharges of the real-time discharge situation. Since the increase in the cumulative number of discharges indicates that the user's discharge is more, and the remaining power of the user may be less. To ensure the safety of vehicle driving, the value of the second discount factor can be reduced.
[0092] In another embodiment, the second discount factor is inversely proportional to the total discharge power of multiple discharges of the real-time discharge situation. Of course, the above k2 can be a functional relationship or a corresponding relationship of a table, which is not limited herein.
[0093] Exemplary one, the functional relationship of k2 can be represented by the following piecewise function:
[0094]
[0095] Exemplary two, the functional relationship of k2 can be represented by the following piecewise function:
[0096]
[0097] Among them, k1 is the first discount factor, V = Q1 / Q2 is the cumulative number of discharges of the real-time discharge situation, Q1 is the discharge capacity of the battery system, and Q2 is the discharge capacity of the battery system that has been used at least once.
[0098] It should be noted that the "first" in the "first discount factor" and the "second" in the "second discount factor" in this article are both discount factors, and the value ranges of both are values greater than 0 and less than or equal to 1, that is, values greater than 0% and less than or equal to 100%. The less than or equal to in this article means less than or equal to.
[0099] The above first optional embodiment and the second optional embodiment can be independently implemented separately or can be implemented in combination. That is, according to the corresponding first discount factor and the corresponding second discount factor, the real-time available power of the vehicle is discounted to obtain the discounted power. In this way, the available power of the vehicle can be discounted more effectively, allowing the user to more intuitively experience the impact of not charging in time on the driving experience.
[0100] Combined Figure 1 and Figure 2 As shown, the above charging method further includes adopting any one of the following methods to detect that the real-time discharge situation during the vehicle operation meets the discount condition:
[0101] In an optional method, it is determined that the cumulative number of discharges of the multiple discharge powers of the battery system reaches the first preset cumulative number.
[0102] In another alternative manner, the total discharge capacity after multiple charging cycles within the battery system's duration exceeds the full charge discharge capacity of the battery system.
[0103] The above charging method further includes: obtaining a reminder for fully charging the vehicle in the following manner: If, within the continuous charging period after the previous reminder is turned off, and the battery system fails to reach full charge multiple times and meets the reminder conditions for fully charging the vehicle, then on the product application of the mobile terminal, a reminder for fully charging the vehicle is generated and indicated. The product application of the mobile terminal may include, but is not limited to, the APP of the mobile terminal. In this way, information is displayed for the user through the cooperation of the mobile terminal and the vehicle display device of the vehicle. Especially during vehicle charging, when the user is away from the vehicle, the user can remotely view the charging information through the mobile terminal.
[0104] In some other embodiments, the above charging method may further include, but is not limited to: after the above step 130, if the current actual power of the battery system reaches full charge, the reminder is turned off. In this way, after forcibly setting the full charge, it is defaulted that the charging ends only when the battery is fully charged. Therefore, the reminder can be directly turned off to save monitoring costs. Exemplarily, the user starts charging at 8:00 pm, and generally the user will not interrupt charging at 0:00 am in the middle of the night until the battery system is fully charged.
[0105] Continuing with Figure 2 As shown, the above step 130 may adopt at least one of the following examples to determine that the running vehicle stops to charge the battery system: In one example, it is detected that the vehicle is connected to the in-vehicle device. In another example, a charging current is detected in the vehicle. In yet another example, a charging request input by the user is received.
[0106] Next, the above step 130 may adopt at least one of the following alternative manners to display the upper limit for forced charging as full charge:
[0107] In one alternative manner, a charging setting interface is displayed; the user's charging upper limit input by the user for the charging setting interface is received; if the user's charging upper limit is not full charge, the user's charging upper limit is forcibly modified to full charge. If the user's charging upper limit is full charge, the battery system is charged according to full charge. In this way, there is a perceptible interaction with the user, allowing the user to intuitively feel the process of forced modification.
[0108] In another alternative manner, regardless of whether the user sets a charging upper limit, when charging the battery system, the upper limit for forced charging is modified to full charge. In this way, as long as charging occurs, the upper limit value for forced charging is directly displayed as full charge, so that the forced modification is displayed, reducing user operations.
[0109] In some alternative embodiments, after the above step 130, it can be determined that the time point is the corresponding time point at night, and the reminder can be directly turned off. In this way, after the full charge is forcedly set, it will be default that the charging ends only when the battery system is fully charged. Therefore, the reminder can be directly turned off to save the monitoring cost. Exemplarily, the user starts charging at 8:00 p.m. Generally, the user will not interrupt the charging at 00:00 in the middle of the night until the battery system is fully charged.
[0110] In addition, continuing as Figure 2 shown, since the above step 130 charges the battery system after the above reminder indication. At this time, the power of the battery system is less than or equal to the power at the reminder indication. Therefore, when charging the battery system, the upper limit for forced charging can be directly displayed as full charge.
[0111] In another example, the above step 130 can further include but is not limited to displaying the upper limit for forced charging as full charge when the vehicle in operation stops to charge the battery system and the battery system is not fully charged. In this way, the power of the battery system can be verified again when charging the battery system to obtain the latest power situation.
[0112] The generation and indication of the above reminder in this article, and / or, the display conditions for displaying the upper limit for forced charging as full charge can be the same. For example, both can be judged by the single charging situation or the cumulative charging situation within a continuous time period. Of course, the display conditions for the two can also be different. For a detailed description, please refer to the following text.
[0113] For the case where the display conditions for the above two are the same, in the first example, it can be detected that the battery system is not fully charged once, then the reminder is generated and indicated, and the upper limit for forced charging is displayed as full charge. In this way, the power can be replenished in time.
[0114] In the second example, if it is detected that the cumulative charging situation within a continuous time period reaches the cumulative condition that the vehicle is not fully charged and the battery system of the vehicle is not fully charged, then the reminder for charging the vehicle fully is generated and indicated, and the upper limit for forced charging is displayed as full charge.
[0115] In the third example, in an example where the above reminder is generated and indicated in the above step 110, if it is detected that the battery system is not fully charged multiple times, then the reminder is generated and indicated. In this way, a fault tolerance space is given to the user, which can improve the user experience effect.
[0116] Correspondingly, in step 130 above, when the vehicle in operation parks to charge the battery system, if it is reminded that the battery system has not been fully charged multiple times during the continuous indication time period, then when the vehicle in operation parks to charge the battery system, the upper limit for forced charging is displayed as full charge. In this way, the charge amount for each of the multiple charges or the multiple charge amounts do not reach the full charge. This improves the effectiveness of forced charging.
[0117] Furthermore, if it is detected that the battery system has not been fully charged multiple times, a reminder is generated and indicated, including that if during the continuous time period of charging after the previous reminder is turned off, and the battery system not being fully charged multiple times meets the reminder condition for the vehicle to be fully charged, then a reminder for fully charging the vehicle is generated and indicated.
[0118] Among them, the following method is used to determine that the battery system not being fully charged multiple times meets the reminder condition for the vehicle to be fully charged: determining that the cumulative number of charging times of the battery system not being fully charged multiple times reaches a first preset cumulative number; or, determining that the cumulative charge capacity of the battery system not being fully charged multiple times exceeds the healthy charge amount of the battery system for multiple charges, such as the healthy charge amount for more than 1.5 times of charging. Among them, the first preset cumulative number is used to represent the first preset cumulative number.
[0119] Figure 3 Shown as Figure 2 A schematic diagram of a specific example of the charging method shown.
[0120] Exemplarily, as Figure 2 and Figure 3 shown, during each battery charging process of vehicle BMS, it is judged whether the reminder condition for the vehicle to be fully charged (also called the indication condition for full charge reminder) is met. If so, that is, the indication condition for full charge reminder, the BMS sends a reminder for the vehicle to be fully charged to the T-BOX, that is, the battery BMS sends a "BMSH_Full ChargeRemind = 0x1: reminder" signal to the T-BOX. After receiving the 0x1 reminder, the T-BOX pushes a text reminder to the APP, that is, "To keep the power battery in the best health condition, it is recommended to fully charge at least once a week". The T-BOX only pushes one message within one cycle of vehicle wake-up.
[0121] Among them, the above indication condition for full charge reminder: when the following conditions are simultaneously met, the BMS sends a "BMSH_FullCharge Remind = 0x1: reminder" signal:
[0122] (1), According to the time point of the T-BOX, it has not been charged to 100% SOC for 30 consecutive days (TBD);
[0123] (2) The cumulative charge capacity Q3 > Q4. Where Q3 = ∫I*dt, Q4 = 5*Q*soh, and the battery is not charged to 100% SOC during the whole process. I is the battery charging current; Q3 is the cumulative charge capacity of the battery system; Q is the nominal capacity of the battery system (such as the capacity of a newly manufactured battery); Soh is the current health state of the battery (the battery capacity will decay after the battery is used for a period of time), with a range of 0% to 100%. Q4 is the charge capacity of the current battery system for 5 times, and it is not fully charged for all 5 times. t is a time point such as Beijing time. When the battery is fully charged, Q3 starts to be calculated from 0 again.
[0124] For the case where the display conditions of the above two are different, as Figure 2 shown, step 130 above may further include when charging the battery system while the running vehicle is parked, if the continuous time period after the reminder indication exceeds the continuous time period for closing the reminder, and the battery system fails to be fully charged multiple times to meet the battery conditions for forced charging, then when charging the battery system while the running vehicle is parked, display that the upper limit for forced charging is the full charge.
[0125] It should be noted that the continuous time period for charging after the previous reminder is closed in this article may be equal to or longer than the continuous time period for closing the reminder.
[0126] Among them, the following optional methods are adopted to determine that the battery system fails to be fully charged multiple times to meet the battery conditions for forced charging:
[0127] In the first optional method, determine that the cumulative number of charging times when the battery system fails to be fully charged multiple times reaches a second preset cumulative number of times.
[0128] The "first" in the "first preset cumulative number of times" and the "second" in the "second preset cumulative number of times" in this article are used to distinguish the two preset cumulative numbers of times, and both are used to indicate that the battery system fails to be fully charged multiple times to meet the battery conditions for forced charging. The first preset cumulative number of times may be equal to or different from the second preset cumulative number of times.
[0129] In the second optional method, determine that the charging power when the battery system fails to be fully charged multiple times exceeds the healthy power for more than one charge of the battery system.
[0130] In the third optional method, determine that the charging frequency time interval when the battery system fails to be fully charged multiple times is greater than a preset interval, and the cumulative charge capacity when the battery system fails to be fully charged multiple times exceeds the healthy power for more than one charge of the battery system.
[0131] The above preset interval is used to represent the user's actual charging behavior to verify that the battery is not fully charged each time, so as to avoid the user charging multiple times in a short period due to abnormal situations. The above preset interval is not less than 1 hour or within 5 hours.
[0132] Generally, the above preset interval can be greater than 12 hours or greater than 1 day or greater than 1 week. In this way, it is avoided that the charging pile is replaced in a short time after the equipment appears, and it is misjudged that the user's battery is not fully charged this time. This provides a fault tolerance space for abnormal situations to occur to the user, thereby improving the application flexibility of the embodiments of the present application and making the method of the present application more user-friendly.
[0133] In the fourth optional method, it is determined that within the continuous time period after the reminder indication, the actual charging frequency of the battery system is greater than the preset charging frequency.
[0134] The above preset charging frequency is used to represent that the user's actual charging behavior is indeed that the battery is not fully charged each time, so as to avoid the user charging multiple times in a short period due to abnormal situations. The above preset interval is not less than 1 hour or within 5 hours.
[0135] The continuous time period after the above reminder indication is directly proportional to the preset charging frequency. The preset charging frequency increases as the continuous time period increases. Further, the continuous time period after the above reminder indication increases in proportion to the preset charging frequency, for example, the value of the preset charging frequency is greater than or equal to 2 times the continuous time period.
[0136] For example, within the continuous time period after the reminder indication is 1 day, the preset charging frequency can be 2 times, and the actual charging frequency is greater than 2 times.
[0137] For another example, within the continuous time period after the reminder indication is 5 days, the preset charging frequency can be 10 times, and the actual charging frequency is greater than 10 times. Examples are not given one by one here.
[0138] Exemplarily, after the battery BMS issues the signal "BMSH_FullChargeRemind = 0x1: reminder", the judgment of enabling the available power discount is carried out. If any of the following conditions is met, the BMBMS starts to limit the available power discount of the battery in the SOC≤20% interval, and a text message "Vehicle power is limited, please immediately charge the vehicle to 100%" pops up on the vehicle display device. The discounted power P1 = P×k1×k2, and the power usage of the vehicle is restricted. Where P is the real-time available power of the BMS, also known as the original available power, P1 is the discounted power, k1 is the first discount coefficient (please refer to Table 1 below) and k2 is the second discount coefficient (please refer to Table 2 below).
[0139] The value of k1 is shown in Table 1 below (linear interpolation)
[0140] SOC (%) ≤5 10 ≥20 k1 0.3 0.7 1
[0141] The value of k2 can be found in Table 2 below (linear interpolation).
[0142] V = Q1 / Q2 ≤1 1.5 ≥2 k2 1 0.7 0.5
[0143] (1) The cumulative discharge capacity Q1 > Q2;
[0144] Among them, Q1 = ∫I*dt, Q2 = 1.5*Q*soh; (Q*soh is the healthy capacity); I is the battery discharge current; Q1 is the battery system discharge capacity; Q is the nominal capacity of the battery system (for example, the capacity of a newly manufactured battery is 5000 mAh); Soh is the current health state of the battery (the battery capacity will decay after the battery has been used for some time), with a range of 0% to 100%, Q2 is the battery system discharge capacity after 1.5 uses, and t is the time point such as Beijing time. Thus, 1.5 times the cumulative discharge capacity does not meet the reminder shutdown condition. Of course, 1.5 here can be replaced with a value greater than 1.5, such as 2, 3, etc., and no further examples will be given here.
[0145] Figure 4 As shown Figure 2 The charging method shown includes a schematic diagram of the reminder shutdown process.
[0146] In another alternative embodiment as Figure 4 shown, in step 140, if the current actual power of the battery system reaches full charge, the reminder is turned off. In this way, the user can be forced to ensure that the set full charge is consistent with the current actual power, which can improve the effectiveness of forced full charge.
[0147] As Figure 3 shown, the current actual power of the above battery system reaching full charge can also be referred to as the shutdown condition for the full charge reminder. The specific shutdown condition for the full charge reminder is as follows:
[0148] When the battery is charged to SOC = 100%, the battery BMS issues a "BMSH_Full Charge Remind = 0x0: reminder off" signal.
[0149] Continuing as Figure 3 and Figure 4As shown, after the battery BMS issues a reminder to indicate that the vehicle is fully charged, it determines whether the closing condition of the full charge reminder is met. If so, that is, if the closing condition of the full charge reminder is met, the battery BMS sends a signal to close the full charge reminder to the T-BOX. That is, the battery BMS sends a signal of "BMSH_Full Charge Remind = 0x0: reminder closed" to the T-BOX. After receiving the 0x0 reminder, the T-BOX stops pushing the reminder in classical Chinese to the APP, and the reminder "To keep the power battery in the best health condition, it is recommended to fully charge it at least once a week" disappears.
[0150] Combined with Figures 1 to 4 As shown, the execution subject of this article is the screen of the vehicle, that is, it is applied to the screen of the vehicle; correspondingly, the above step 110 may include the following first step. The above step 140 may include the following second step. The above step 140 may include the following third step.
[0151] The first step: Receive a reminder display instruction generated by a device with information processing function of the vehicle, and display the reminder on the screen.
[0152] The above reminder display instruction is used to display the reminder. The reminder may include reminder content with a reminder purpose. For example, the text or voice reminder is "To keep the power battery in the best health condition, it is recommended to fully charge it at least once a week".
[0153] The second step: If it is received that the device with information processing function determines to charge the battery system, display the upper limit for forced charging as full charge on the screen.
[0154] The third step: If it is received a reminder closing instruction generated when the device with information processing function determines that the current actual power of the battery system reaches full charge, close the display of the reminder on the screen.
[0155] The above reminder closing instruction is used to close the display of the reminder. In this way, the reminder content with a reminder purpose can be closed.
[0156] Of course, the above device with information processing function may also be a device with information processing function or a battery BMS, etc., and no further examples are given here.
[0157] In the embodiment of the present application, the display and reminder can be realized through the device with information processing function of the vehicle itself, without changing the hardware structure, and the display in the vehicle and the automatic forced modification of the charging SOC limit value to full charge can be achieved.
[0158] Combined with Figures 1 to 4As shown, the execution entity of this article is the APP (Application Program) of the mobile terminal, that is, the APP applied to the mobile terminal that is communicatively connected to the vehicle; correspondingly, the above step 110 may include the following step 1. The above step 140 may include the following step 2. The above step 140 may include the following step 3.
[0159] Step 1: Receive a reminder display instruction generated by a device with information processing function of the vehicle, and display a reminder on the APP.
[0160] Step 2: If it is received that the device with information processing function determines to charge the battery system, then display the upper limit for forced charging as full charge on the APP.
[0161] Step 3: If a reminder off instruction generated when the device with information processing function determines that the current actual power of the battery system reaches full charge is received, then turn off the display of the reminder on the APP.
[0162] In the embodiment of the present application, remote display and reminder can be realized through the interaction between the device with information processing function of the vehicle and the mobile terminal, and the charging SOC limit value can be automatically and forcibly modified to full charge.
