Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a battery charging method, device, electronic equipment and storage medium. Background Art

[0002] At present, the low-voltage batteries of electric vehicles are all lead-acid batteries, which are mainly used to store low-voltage system energy for activating high-voltage systems. However, with the application of network connection technology, after the vehicle is powered off and locked, some network-related functions can still activate the low-voltage system to work, so low-voltage lead-acid batteries also have the function of independent power supply in some scenarios. How to ensure that the low-voltage battery does not lose power for a long time to affect the function and does not waste high-voltage battery energy and overcharge is a difficult problem faced by electric vehicles. When the vehicle is in power-off dormancy, the previous vehicle controller (VCU / HCU) determines whether the low-voltage battery meets the preset charging conditions based on the power parameters of the low-voltage battery. If the low-voltage battery meets the preset charging conditions, the high-voltage system is controlled to charge the low-voltage battery according to the preset charging voltage; another method is to use a battery sensor to monitor the battery state of charge SOC value. When the battery is detected to be depleted to the set threshold, the DC / DC converter is activated to charge to ensure that the battery is not depleted.

[0003] In the second charging method mentioned above, since the existing battery sensor (IBS) calculates the capacity SOC by accumulating the integral according to the battery discharge current, when the vehicle battery is seriously depleted or the battery is discharged at a large current, the battery voltage will drop rapidly. At this time, the memory effect will cause the battery capacity SOC to differ from the voltage change, making the actual capacity of the battery capacity (SOC) inconsistent with the indicated capacity in the accumulated tolerance, affecting the judgment of the charging logic. Summary of the invention

[0004] The present invention provides a battery charging method, device, electronic device and storage medium to solve the technical problem that when a vehicle battery is seriously depleted or the battery is discharged at a large current, the battery voltage drops rapidly, resulting in a difference between the battery capacity SOC and the voltage change, causing the accumulated tolerance of the battery capacity (SOC) to show that the actual capacity is inconsistent with the indicated capacity, thereby affecting the judgment of the charging logic.

[0021] The battery charging module is used to obtain the charging logic corresponding to the battery, and then compare the first comparison result and the second comparison result with the charging logic.

[0047] Embodiment 1

[0048] Please refer to Figure 1, is a flow chart of a battery charging method provided by an embodiment of the present invention, comprising the following specific steps:

[0049] S1. Collecting current battery parameter information of the battery; wherein the current battery parameter information includes: battery capacity and battery voltage;

[0050] Preferably, the collecting of the current battery parameter information of the battery includes: after the vehicle is powered off, waking up the vehicle network at intervals of a preset wake-up time and collecting the current battery parameter information of the battery.

[0051] For details, please refer to Figure 2 , is a battery charging logic diagram based on big data. The specific battery charging method is as follows:

[0052] (1) After the vehicle is powered off, the network wakes up at a scheduled time after a certain period of time (the duration can be calibrated). The TBOX wakes up the vehicle-specific network. At this time, the battery sensor (normal power node) collects the current battery parameter information of the battery (including the battery capacity SOC and the battery voltage LowBatVol).

[0053] S2, comparing the battery capacity with a preset battery capacity charging threshold to obtain a first comparison result, and comparing the battery voltage with a preset battery voltage charging threshold to obtain a second comparison result;

[0054] (2) Compare the battery capacity with a preset battery capacity charging threshold to obtain a first comparison result, and compare the battery voltage with a preset battery voltage charging threshold to obtain a second comparison result. In a specific embodiment, the battery capacity charging threshold can be set to 50% SOC, and the battery voltage charging threshold can be set to 11.9V to obtain a first comparison result; compare the current battery capacity SOC of the battery with the preset 50% SOC, and compare the current battery voltage of the battery with the preset 11.9V voltage to obtain a second comparison result.

[0055] S3. Obtain the power replenishment logic corresponding to the battery, and then compare the first comparison result and the second comparison result with the power replenishment logic. When the first comparison result and the second comparison result satisfy the power replenishment logic, determine that the battery satisfies the power replenishment condition, replenish the battery, and stop replenishing the battery when the battery capacity reaches a preset power replenishment termination condition.

[0056] Preferably, the comparing the first comparison result and the second comparison result with the power replenishment logic, and when the first comparison result and the second comparison result satisfy the power replenishment logic, determining that the battery satisfies the power replenishment condition, and recharges the battery, comprises: comparing the first comparison result and the second comparison result with the power replenishment logic, and when the battery capacity is less than a preset battery capacity recharge threshold and the battery voltage is not greater than a preset battery voltage recharge threshold, the battery capacity is equal to a preset battery capacity recharge threshold and the battery voltage is greater than a preset battery voltage recharge threshold, or the battery capacity is greater than a preset battery capacity recharge threshold and the battery voltage is not greater than a preset battery voltage recharge threshold, determining that the battery satisfies the power replenishment condition, and recharges the battery; when the battery capacity is greater than a preset battery capacity recharge threshold and the battery voltage is greater than a preset battery voltage recharge threshold, determining that the battery does not satisfy the power replenishment condition, and does not recharge the battery.

[0057] Preferably, after the battery is recharged, the method further includes: recording the recharging time of the battery, and when the recharging time reaches a preset recharging time threshold, comparing the current battery capacity with the recharging termination condition; if the battery capacity has reached the recharging termination condition, stopping the recharging and determining that the battery recharging is successful; if the battery capacity has not reached the recharging termination condition, stopping the recharging, counting the current recharging times of the battery, and re-determining whether the battery meets the recharging conditions; when the battery meets the recharging conditions, re-recharging the battery until the battery capacity reaches the recharging termination condition; if the battery capacity has not reached the recharging termination condition when the recharging times reaches the preset recharging times threshold, determining that the battery has a recharging abnormality and generating a corresponding abnormality alarm.

[0058] (3) Please refer to Figure 3 , which is a schematic diagram of the battery status corresponding to different vehicle use scenarios. After comparing the first comparison result and the second comparison result, according to Figure 3 The battery usage scenario shown is matched to obtain the corresponding charging logic, and the first comparison result and the second comparison result are compared with the charging logic to determine whether the current battery capacity and battery voltage of the battery meet the corresponding charging logic. In a specific embodiment, when the current battery signal meets the charging precondition (at least one of the battery SOC and voltage status bits are satisfied), the battery is charged, and when the charging condition is met, the vehicle controller VCU counts the charging status position +1. If the current battery SOC after charging is greater than 80% SOC, the current charging cycle is terminated.

[0059] In a specific embodiment, the power replenishment logic selects: Condition A: battery SOC; Condition B: battery voltage LowBatVo l. If condition B is met and condition A is 50%, the power replenishment termination condition is executed and power replenishment is performed at 80% SOC. If condition B is not met (B<11.9V) and condition A≠50% (>50% or <50%), the current power replenishment logic performs power replenishment according to the power replenishment duration of 3h.

[0060] After the start of the charging, if the charging effect (high battery power) is still not achieved within the current charging cycle (generally measured by power or timing for 3 hours), the current charging endurance will be exited, and the current charging times will be uploaded to the cloud service platform through TBOX, and the next charging cycle will continue, and the current charging cycle timing will be +1. After the number of charging reaches 3 times, the VCU uploads the charging times 3 and outputs the abnormal charging type flag, and uploads the abnormal charging type flag to the big data. In order to avoid invalid charging, the current charging cycle is controlled to end. In view of this, the present invention uses a strategy to make up for the shortcomings of the existing charging strategy. At the same time, the charging strategy comprehensively considers that the single charging power generated by the battery due to its own reasons cannot be effectively supplemented, triggering the system to perform multiple charging. When the number of charging exceeds a certain number (the existing calibration quantity: the number is 3), TBOX uploads big data and interrupts the current charging cycle. The battery charging is interrupted to save the power battery power.

[0061] It can be seen that the present invention provides a battery charging method. The local battery charging strategy of the present invention is designed based on the actual use scenario of the whole vehicle. It is more in line with the actual use scenario of the customer than a single message (SOC or voltage). It can also make up for the shortcomings of sensor indication information and indication deviation based on the optimization of the charging logic in special use scenarios. In the short term, it is impossible to optimize the sensor signal acquisition algorithm. The vehicle intelligent charging test of various working conditions is fully covered, and the success rate of vehicle charging in the case of power loss is improved, while saving energy for the whole vehicle and society. The following beneficial effects can be achieved by the present invention:

[0062] (1) Cost and time savings: Through intelligent charging strategy optimization based on big data, the accessibility and success rate of vehicle charging can be significantly improved, saving the overall energy consumption of charging and reducing the energy costs required for charging for customers;

[0063] (2) Power scenario coverage: Different from the traditional method of collecting and judging the single signal of battery capacity (SOC) and voltage (Lowbattery), the system performs logical judgment by comparing the two signals, thereby extending the coverage bandwidth of power replenishment scenarios.

[0064] (3) Customer experience: Due to the improvement in the success rate of charging, users can have a better car experience and service experience;

[0065] (4) Supplementing project development experience: Based on big data problem analysis, problems can be discovered and intervened in advance, creating favorable conditions for the introduction of vehicle production and quickly accumulating development experience for the project;

[0066] (5) Accumulate vehicle usage data: Collect and track the analysis of problems generated after the sale of various models to provide data support, facilitate faster solutions to problems, realize the efficiency of mining quality problems in unknown scenarios, and improve the efficiency of problem solving.
