Based on the charging characteristics of lead-acid batteries, the charging time required to increase the remaining capacity of the battery by a preset percentage at the current temperature is calculated according to the battery's charging and discharging history data. In response to the fact that the longest possible low-voltage upgrade duration is less than the total low-voltage upgrade duration of the current upgrade task, the preset upgrade sequence is adjusted to obtain the actual upgrade sequence of the controller; In response to the fact that the longest possible low-voltage upgrade duration is greater than or equal to the total low-voltage upgrade duration of the current upgrade task, the preset upgrade sequence will be used as the actual upgrade sequence of the controller.

[0027] In some embodiments, in response to the fact that the longest possible low-voltage upgrade duration is less than the total low-voltage upgrade duration of the current upgrade task, the preset upgrade sequence is adjusted to obtain the actual upgrade sequence of the controller, including: In response to the fact that the longest possible upgrade time under low voltage is less than the total upgrade time under low voltage for the current upgrade task, the upgrade time of each controller under low voltage and the upgrade time of each controller under high voltage are sorted in ascending order respectively.

The power replenishment value during the high-voltage upgrade process is calculated based on the charging time required for the remaining battery charge to increase by a preset percentage at the current temperature and the total upgrade time under high voltage. Obtain the current battery level and calculate the new duration of low-voltage upgrade support based on the current battery level and the replenishment value; In response to the new support for low-voltage upgrade durations greater than or equal to the first and second low-voltage upgrade durations, the actual upgrade sequence is generated after executing the initial controller upgrade sequence and after executing the upgrades for the first and second low-voltage upgrade durations.

[0029] In some embodiments, it also includes: In response to the fact that the longest possible low-voltage upgrade duration is less than the difference between the total low-voltage upgrade duration of the current upgrade task and the durations of the first and second low-voltage upgrades, or the longest possible low-voltage upgrade duration is greater than or equal to the difference between the total low-voltage upgrade duration of the current upgrade task and the durations of the first, second, and third low-voltage upgrades, the process of generating the initial controller upgrade sequence, calculating the power replenishment value during the high-voltage upgrade process, and calculating the new supported low-voltage upgrade duration is executed to generate the actual upgrade sequence. In response to the fact that the longest possible low-voltage upgrade duration is less than the difference between the total low-voltage upgrade duration of the current upgrade task and the durations of the first and second low-voltage upgrades, the system iteratively executes the process of comparing the longest possible low-voltage upgrade duration with the corresponding difference, generating the initial controller upgrade sequence, calculating the supplementary power value during the high-voltage upgrade process, and calculating the new possible low-voltage upgrade duration to generate the actual upgrade sequence. This process continues until the longest possible low-voltage upgrade duration is less than the difference between the total low-voltage upgrade duration of the current upgrade task and all low-voltage upgrade durations except for the last low-voltage upgrade duration, generating the actual upgrade sequence of executing the high-voltage upgrade for the first high-voltage upgrade duration. The power replenishment value during the high-voltage upgrade process is calculated based on the charging time required for each preset percentage increase in the remaining battery capacity at the current temperature and the first high-voltage upgrade time. Obtain the current battery level and calculate the new duration of low-voltage upgrade support based on the current battery level and the replenishment value; In response to the new support for low-voltage upgrade duration being greater than or equal to the total low-voltage upgrade duration of the current upgrade task, the preset upgrade order will be used as the actual upgrade order.

[0030] In step S103, in response to the low-voltage battery charge being less than or equal to the actual battery charge before the upgrade, each controller is upgraded based on the actual upgrade sequence of the controllers.

[0031] In actual execution, when the OTA upgrade process enters the pre-upgrade condition detection stage, the basic information collected in step S101 is calculated according to the following data processing procedure to obtain the vehicle's high and low voltage upgrade controller sequence and the low-voltage battery charge before the upgrade. The controller upgrade sequence and the minimum SOC of the low-voltage battery as a pre-upgrade condition are then input to the OTA main control program. The main control program compares this with the actual battery charge. If the conditions are met, the upgrade proceeds according to the input upgrade sequence; otherwise, the upgrade is terminated, and a message is displayed indicating insufficient battery charge, preventing the upgrade. The specific data processing procedure is as follows: Step 1, from OTA The platform obtains information on each controller under low voltage and the upgrade duration for the current upgrade task. L 1, L 2, L 3, ..., L N Calculate the total upgrade time under low pressure for the current upgrade task. T L = L 1+ L 2+ L 3+...+ L N .

[0032] Step 2, from OTA The platform obtains information about the controller under high voltage and the upgrade duration for the current upgrade task. H 1, H 2, H 3, ..., H N Calculate the total upgrade time under low pressure for the current upgrade task.T H = H 1+ H 2+ H 3+...+ H N .

[0033] Step 3, using basic information obtained from the low-voltage battery controller: current battery level. SOC Battery health SOH ,capacity C Low-voltage upgrade of vehicle static current I (Calibrable), calculates the current ambient temperature. t The longest duration that can be supported for low-voltage upgrades T The specific calculation formula (1) is as follows: Ambient temperature t ≥0℃, T =( SOC -30%)* C * SOH *60 / I Unit: minutes; Ambient temperature -10℃≤ t <0℃, T =( SOC -40%)* C * SOH *60 / I Unit: minutes; Ambient temperature t Upgrades are not allowed if the temperature is below -10℃.

[0034] Step 4: Utilize the historical charging data (including battery level) of the currently upgraded vehicle's battery obtained from the cloud control platform. SOC Battery health SOH (Collect average charging current, charging time, etc.) and calculate the battery's current temperature based on the lead-acid battery's charging characteristics. SOC Charging time required for each 1% increase t 1% The data is checked in real time according to changes in ambient temperature, battery status and historical data, and invalid data is removed. The specific calculation formula (2) is as follows:

[0035] In the formula, The reference charging current is the vehicle model calibration value. The platform collects the average charging current value, Δ t At the current temperature SOC The charging time required for each 1% increase, Δ SOC During this period SOCTotal increase (end) SOC -start SOC (Except for jumps / outliers). k T Temperature correction factor (T<0℃), k T =1.4; 0℃≤ T <10℃, k T =1.2, 10℃≤ T ≤45℃, k T =1.0; T >45℃, k T =1.4).

[0036] Step 5, if T ≥ T L The battery supports a low-voltage upgrade duration longer than the actual low-voltage upgrade task duration. The upgrade will proceed in the default upgrade order without any special handling.

[0037] Step 6, if T < T L If the battery's supported low-voltage upgrade time is less than the actual low-voltage upgrade time required for the upgrade task, the upgrade sequence will be adjusted as follows: Figure 3 As shown: Step 6.1, low-voltage upgrades are reordered according to upgrade duration from shortest to longest: L 1, L 2, L 3, ..., L N High-voltage upgrades are reordered based on upgrade duration, from shortest to longest: H 1, H 2, H 3, ..., H N ; Step 6.2, Current SOC Next, if T ≥ T L - L 1. If the battery's supported low-voltage upgrade time is greater than the actual low-voltage upgrade time minus the minimum low-voltage upgrade time, then the upgrade time performed first will be [the specified value]. L 2, L 3, ..., L N The controller was upgraded under low voltage, and the upgrade time was... H 1, H 2, H 3, ...,H N The controller is upgraded under high voltage. The total time for high voltage upgrade is calculated according to formula (2). t The ratio of 1% is used to calculate the Δ increase in power supply during the high-voltage upgrade process. SOC Calculate the new battery according to formula (1) SOC _ total =Δ SOC + SOC Support for low-voltage upgrade duration T Is it greater than or equal to? L 1. If yes, proceed. L If you fail to upgrade, you will be prompted that the battery power is insufficient and you cannot upgrade.

[0038] Step 6.3, Current SOC Next, if T < T L - L 1, then calculate T ≥ T L - L 1- L 2. If the condition is met, then proceed with the upgrade for the specified duration. L 3, ..., L N The controller was upgraded under low voltage, and the upgrade time was... H 1, H 2, H 3, ..., H N The controller is upgraded under high voltage. The total time for high voltage upgrade is calculated according to formula (2). t 1% The ratio of Δ to the power increase during the high-voltage upgrade process is used to calculate the power increase Δ. SOC Calculate according to formula (1) SOC _ total =Δ SOC + SOC Support for low-voltage upgrade duration T Is it greater than or equal to? L 1+ L 2. If yes, proceed. L 1, L 2. Upgrade is possible; otherwise, a message will appear indicating insufficient battery power, preventing the upgrade.

[0039] Step 6.4, based on steps 6.2 and 6.3, and so on, outputs the controller upgrade sequence for alternating high and low voltage operation. L X ,..., L N , H 1, H 2,H 3, ..., H N , L 1, L 2, ..., L X-1 This maximizes the use of high-voltage upgrades to replenish battery power, reducing the proportion of batteries that cannot be upgraded due to low battery capacity.

[0040] Step 6.5, under the current SOC, if T < T L - L 1-...- L N-1 Then, high-voltage upgrades will be carried out first. H 1. Calculate the high-voltage upgrade time according to formula (1). H 1 and t 1% The ratio of Δ to the power increase during the high-voltage upgrade process is used to calculate the power increase Δ. SOC Calculate according to formula (1) SOC _ total =Δ SOC + SOC Value supports low-voltage upgrade duration T new ,if T new ≥ T L Then return to steps 5 and 6 and repeat the process. If... T new < T L Then high voltage upgrade will be carried out. H 1, H 2. Repeat step 6.5 to calculate the new... T new And so on. If all high-voltage upgrade controllers have been upgraded, and the problem persists... T new < T L If the battery is low, an upgrade cannot be performed.

[0041] Through the calculations and judgments in steps 1-6, this embodiment of the invention can intelligently and dynamically adjust the execution order of high-voltage and low-voltage upgrades, fully utilizing the characteristic that the vehicle can automatically replenish the low-voltage battery during the high-voltage upgrade process, thus achieving a dynamic balance between high-voltage upgrade replenishment and low-voltage upgrade power consumption. By calculating the battery's support time, high-voltage replenishment gain, and remaining low-voltage upgrade requirements in real time, the battery is rationally adjusted. SOC The system enables flexible adjustment of the low-voltage battery charge without adding hardware or changing the overall vehicle structure.

[0042] Finally, the upgrade sequence of the high and low voltage controllers adapted to the current battery status will be output to...

Through an integrated strategy of real-time battery status calculation, dynamic adjustment of high and low voltage upgrade sequence, and automatic power replenishment during high voltage upgrade, it fundamentally solves the problem of upgrade failure under low battery conditions, and has the following beneficial effects: (1) Say goodbye to fixed upgrade order, and the upgrade success rate is greatly improved; (2) Intelligent calculation based on the actual state of the battery, rather than a fixed state. SOC Threshold; (3) Utilize the high-voltage upgrade process to automatically replenish power, thereby achieving simultaneous upgrade and charging; (4) A multi-level fallback strategy is adopted, which involves skipping one short-term low voltage, skipping multiple voltages, and replenishing high voltages one by one. The upgrade can be completed without charging as much as possible. Only when all high voltages are replenished and the problem is still not satisfied will the power supply be indicated. The fault tolerance is far superior to the traditional solution.
