Description

Technical Field

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

[0002] In recent years, the development of electric vehicles has become an inevitable trend in the development of the automobile industry. For pure electric vehicles, there are mainly two energy supply modes: vehicle charging and battery replacement.

[0003] At present, electric vehicles are charged by whole vehicle AC slow charging, which takes a long time and has limited parking spaces; DC fast charging has high power and short charging time, but has a greater impact on the power grid and reduces the battery life. The battery replacement mode is used to charge by allocating different charging powers to the peak and valley frequencies of battery replacement. During the peak period of battery replacement, the charging power is increased to speed up the charging speed of the battery pack, and during the valley period of battery replacement, the charging power is lowered for trickle charging, and the fully charged batteries are stored for vehicle battery replacement.

[0004] Based on the above-mentioned existing technical solutions, when charging in battery replacement mode is adopted, different charging powers are allocated to the peak and valley frequencies of battery replacement until the battery is fully charged. The storage method of the battery replacement battery is generally to store it when the battery is fully charged. Such a storage method is not conducive to the use of the battery, and will accelerate the attenuation of the battery capacity to varying degrees and shorten the battery life.

[0047] Embodiment 1

[0048] Figure 1 This is a flow chart of a battery charging method provided in the first embodiment of the present invention. This embodiment is applicable to the case of charging and storing vehicle batteries. The method can be executed by a battery charging device, which can be implemented in the form of hardware and / or software. The battery charging device can be configured in an electronic device configured in a battery swap station, such as a battery swap station control system. The electronic device may include but is not limited to a computer, a mobile phone or a server. Figure 1 As shown, the method includes:

[0049] S110 : For a battery to be charged, controlling the battery to be charged to be charged in the first stage.

[0050] S120: When the power level of the battery to be charged meets the storage power condition, the first stage of charging is terminated.

[0051] Among them, the battery to be charged can be specifically understood as a battery with low remaining power or replaced from a battery-swapping vehicle. The remaining power is generally represented by a percentage, using the SOC (State of Charge) value, which can also be called the remaining power. A remaining power threshold can be set by the charging control system to determine whether the battery needs to be charged. For example, the battery threshold for the remaining power is set to 30%. If the battery's SOC value is less than 30%, the battery can be charged through charging equipment such as charging piles. The driver can also independently determine whether the vehicle battery needs to be charged based on his own itinerary. If necessary, the vehicle battery is also a battery to be charged.

[0052] For any battery to be charged, it is connected to a charging device, and the charging device charges the battery to be charged. At the same time, the battery power data of the battery to be charged is collected by the charging device, and the detected battery power data is transmitted to the battery swap station control system in this embodiment, wherein the charging device and the battery swap station control system can be communicatively connected and can perform data transmission.

[0053] Since the battery to be charged is replaced from the battery-swapping vehicle, the battery needs to be stored during the process of being replaced in the vehicle next time, but both under-charged storage and fully-charged storage are not conducive to the battery life. In this embodiment, the battery to be charged is charged in stages. Staged charging is a strategy set to ensure that the battery to be charged can be in a good charging state. It is mainly judged and set based on the SOC value of the battery to be charged, the demand for battery replacement, the charging consumption information and other data. The prediction model can be used to analyze the SOC value of the battery to be charged, the demand for battery replacement, the charging consumption information and other data to obtain a staged charging strategy suitable for the battery to be charged.

[0054] Specifically, the charging process is divided into two stages, and the charging of the battery to be charged is controlled to be performed in the first stage. When the power storage condition is met, the battery to be charged is stored to optimize the service life of the battery. Specifically, the charging device can be controlled to charge the battery to be charged in the first stage by sending a control instruction to the charging device, wherein the control instruction includes but is not limited to the charging start time, the charging end time and the charging rate, etc. Optionally, the charging rate may correspond to the fast charging current (such as the maximum charging current) of the battery to be charged. For example, the first charging rate may be set to 1C. If the nominal capacity of the battery to be charged is 1000mAh, the corresponding fast charging current is 1A. If the nominal capacity of the battery to be charged is 2000mAh, the corresponding fast charging current is 2A. Among them, the charging rate of the first stage may be a preset rate that is conducive to optimizing the battery life, and the preset rate may be determined according to the battery type.

[0055] Optionally, before controlling the first stage charging of the battery to be charged, the method further includes: determining a storage power condition corresponding to the battery to be charged according to the battery type of the battery to be charged, wherein the storage power condition includes a storage power threshold.

[0056] Among them, the storage power threshold can be specifically understood as a storage power threshold that is beneficial to optimizing the battery life when the battery is in a storage state. If the battery is stored when the remaining power of the battery is equal to the storage power threshold, the decay rate of the battery capacity can be reduced. For different battery types, the corresponding storage power threshold may be different. The battery type and the storage power threshold are in a corresponding relationship. The storage power threshold corresponding to the battery type can be obtained through experimental data. Accordingly, by obtaining the battery type of the rechargeable battery, the storage power condition of the battery to be charged can be determined. The battery type of the battery to be charged can be obtained by a battery identification device, or determined by the charging device to which the battery to be charged is connected, such as by reading a preset field identifier of the data stored in the battery to be charged. Optionally, the charging device sends the charging device identifier and the battery type identifier of the connected battery to be charged to the battery swap station control system, and the battery swap station control system determines the corresponding storage power threshold, that is, the storage power condition, based on the battery type identifier.

[0057] For example, after the battery to be charged is replaced from the vehicle, it is connected to a charging device, which identifies the single cell voltage of the battery and charges it to about 50% SOC within a limit of 2.7V for storage, thereby increasing the SOC and shortening the battery charging time.

[0058] In this embodiment, basic information and a storage power threshold of the battery to be charged are determined, and the charging of the battery to be charged in the first stage is controlled according to the basic information and the storage power threshold of the battery to be charged.

[0059] The storage power condition can be specifically understood as the power condition under which the battery to be charged can enter the storage state. If the battery to be charged is charged until the battery storage power reaches the storage power threshold, it can be determined that the battery to be charged meets the storage power condition.

[0060] Specifically, the battery type of the battery to be charged can be identified and the storage power condition can be determined. During the charging process of the battery to be charged, the power of the battery to be charged can be detected in real time, and the detected power can be matched with the storage power condition. If the matching result is consistent, it means that the power of the battery to be charged meets the storage power condition. At this time, the charging of the battery to be charged can be stopped to end the first stage of charging. Specifically, the battery power sent by the charging device in real time or at a fixed time can be received, and when the battery power meets the storage power condition, a stop charging instruction can be sent to the charging device.

[0061] Exemplarily, the storage power condition is set to an SOC value of 50%, and low-power slow charging can be used to supplement the power. When the battery to be charged is charged to an SOC value of 50%, the charging can be terminated, ending the first stage of charging, waiting for the recharging instruction from the battery swap station control system to proceed to the next stage of charging.

[0062] In this embodiment, by real-time detection of the power of the battery to be charged during the charging process, if the power of the battery to be charged meets the storage power condition, it is determined that the power of the battery to be charged meets the storage power condition, and the battery control system can end the charging process of the battery to be charged, completing the first stage of the charging process. By controlling the end of the first stage of charging in this way, the remaining power of the battery to be charged is in a state suitable for storage, avoiding the attenuation of the battery capacitance caused by excessive storage power of the battery, so as to effectively optimize the service life of the battery.

[0063] S130. Determine the start time information of the second stage of the battery to be charged based on the battery swapping demand of the battery swapping station and / or the charging consumption information at each moment, and control the second stage of charging of the battery to be charged based on the start time information of the second stage.

[0064] Specifically, the battery swap demand can be understood as the demand for available batteries for battery swap vehicles at the battery swap station in the future time period, and the battery swap demand includes the demand for available batteries in each unit time period in the future time period. The battery swap demand can be predicted based on historical battery swap data, or it can be determined based on the number of battery replacement requests received. For example, the battery swap demand information reported by users can be received through SMS, phone calls, applications, etc., which can include information such as battery model and battery swap time.

[0065] The charging consumption information at each time specifically refers to the electricity charge standards at each time. For example, the peak hours are 7:00-11:00 and 19:00-23:00, and the electricity price is 0.5583 yuan / kWh; the off-peak hours are 23:00-7:00 the next day, and the electricity price is 0.3583 yuan / kWh; the normal period is 11:00-19:00, and the electricity price is 0.5283 yuan / kWh, etc. The electricity charge standards may vary at different times or in different regions.

[0066] The second stage can be specifically understood as the second stage in the staged charging of the battery to be charged, which is used to charge the battery to be charged until it is fully charged. The start time information of the second stage is determined based on further analysis of the battery swapping demand of the battery swapping station and / or the charging consumption information at each moment. The battery swapping demand of the battery swapping station and / or the charging consumption information at each moment can be analyzed through the demand analysis model to obtain the start time of the second stage of the battery to be charged. Based on the determined start time of the second stage, the battery is charged for the second stage.

[0067] Specifically, the battery swap station control system can analyze the received battery swap demand information and charging consumption information at each moment, and can process it through a data analysis model to obtain the corresponding second-stage charging duration, charging power and other information of the battery to be charged, determine the start time of the second stage, and the battery charging system controls the second-stage charging of the battery to be charged according to the obtained start time.

[0068] A control instruction is sent to the charging device according to the determined start time information of the second stage, so that the charging device charges the battery to be charged based on the start time information of the second stage until the power of the battery to be charged meets the charging end condition, and the charging of the second stage is stopped.

[0069] The technical solution of this embodiment is to obtain the battery swap demand and / or charging consumption information at each moment received by the battery swap station through the control system of the battery swap station, and the data analysis model analyzes the information to obtain the time of staged charging, storage power conditions, and the start time of the second stage, so as to complete the segmented charging of the battery to be recharged. The battery to be recharged is charged in stages, and the battery that has completed the first stage of charging is stored according to the obtained storage power conditions. The battery control system controls the execution of the second stage of charging according to the start time of the second stage, so that the battery to be recharged can be charged as needed, avoiding the situation where it cannot be replaced in time after being fully charged and the situation where it is replaced before being fully charged, thereby reducing energy consumption.

[0070] Embodiment 2

[0071] Figure 2 This is a flow chart of a battery charging method provided in the second embodiment of the present invention. This embodiment optimizes the method based on the above embodiment, and determines the starting time information of the second stage of the battery to be charged based on the battery replacement demand of the battery replacement station. Optionally, the peak period of battery replacement in the battery replacement demand of the battery replacement station is determined, and the starting time information of the second stage is determined based on the peak period of battery replacement and the charging duration of the second stage. Figure 2 As shown, the method includes:

[0072] S210: For the battery to be charged, control the battery to be charged to perform the first stage of charging.

[0073] S220: When the power level of the battery to be charged meets the storage power condition, the first stage of charging is terminated.

[0074] S230. Determine the peak period of battery swapping in the battery swapping demand of the battery swapping station, and determine the starting time information of the second stage based on the peak period of battery swapping and the charging duration of the second stage.

[0075] Among them, the peak period of battery swapping refers to the period when the demand for battery swapping is high. Specifically, it can be understood as one or more periods in a day when the number of battery swapping requests received by the control system of the battery swapping station is relatively large. This period includes but is not limited to one hour, two hours, etc., and the judgment can be completed by setting a threshold for the number of battery swapping requests. For example, the peak period of battery swapping in a day is calculated, and the threshold for battery swapping requests is set to 100 per hour. The actual number of battery swapping requests in each hour is compared with the threshold for the number of battery swapping requests. The time period exceeding this threshold for the number of battery swapping requests can be regarded as the peak period of battery swapping; it can also be judged by the battery swapping prediction model. The charging time of the second stage can be specifically understood as the length of time required for the storage capacity of the battery to be charged to be charged from the state of charge that meets the storage conditions to the full state. It can be calculated by a formula model or by a control system.

[0076] Specifically, according to the battery swapping demand of the battery swapping station collected by the battery swapping station control system, a certain method is used to determine the peak battery swapping time of the day, such as setting a battery swapping request number threshold, dividing the day into hours, and subtracting the actual number of battery swapping requests received in each time period from the battery swapping request number threshold. If the difference is greater than zero, it means that the time period can be regarded as a peak battery swapping time period. Similarly, the time periods that meet the battery swapping request number threshold are obtained in turn. Based on the battery swapping time, battery swapping demand, and SOC value of the battery to be charged, the start time information of the second stage of the battery to be charged is calculated.

[0077] Optionally, historical battery replacement data is obtained, the battery replacement amount in each historical unit time period is counted, and the peak battery replacement period is determined based on the battery replacement amount in each historical unit time period.

[0078] Among them, the historical battery swap data can be specifically understood as the battery swap history record in the battery swap station, which can be read from the database in the battery swap station control system or from the server, without limitation here. The amount of battery swaps in the historical unit time period can be specifically understood as the total amount of battery swaps accumulated in the past unit time period, where the unit time period can be set according to actual needs, and can be set to one day, one week, etc., without limitation here. The peak time period for battery swaps is determined based on the statistical amount of battery swaps in each historical time period, which can be determined by setting parameter thresholds or by a prediction model.

[0079] Specifically, the historical battery swap data obtained is divided into time periods for statistics. The division of time periods can be set according to demand. For example, if you want to obtain the peak time period of the day, you can set one hour as the unit time period, and count the amount of battery swaps in each hour to obtain the amount of battery swaps in each unit time period. The peak value threshold of battery swaps is set by setting the parameter threshold method. If the amount of battery swaps in a unit time period is greater than the peak value threshold of battery swaps, this period is the peak time period of battery swaps.

[0080] Optionally, historical battery swapping data is obtained, and the historical battery swapping data is processed based on a battery swapping prediction model to obtain predicted battery swapping amounts for each time period within the prediction time range, and peak battery swapping periods are determined based on the predicted battery swapping amounts for each time period.

[0081] Among them, the prediction model is a model that analyzes historical data through a certain analysis method to obtain the data development law to predict the corresponding data in the future time period. The battery swap prediction model can be specifically understood as a model that analyzes historical battery swap data to obtain the predicted battery swap volume within the prediction time range, thereby determining the peak battery swap period within the prediction time period. Optionally, the prediction model can be a machine learning model, and further, the prediction model can be a neural network model.

[0082] Exemplarily, the acquired historical battery swapping data is analyzed, the unit time is set to one hour, the battery swapping amounts within all unit times in the past month are counted, the battery swapping amount value within the unit time period is obtained, the battery swapping amount within each unit time period is input as an input parameter into the battery swapping prediction model, the predicted battery swapping amount within each unit time period is output, the predicted battery swapping amount is analyzed again, a peak power threshold is set, and the unit time period to which the battery swapping amount exceeding this threshold belongs is the peak battery swapping time period.

[0083] Optionally, obtain battery swap reservation orders, count the reservation order data for each future time period, and determine the peak time period for battery swap based on the reservation order data for each future time period.

[0084] Among them, the battery swap reservation order can be specifically understood as a battery swap reservation request sent by the user to the battery swap station control system through an application, telephone, etc.

[0085] Specifically, the battery swapping station control system receives the battery swapping demands issued by users for battery swapping in future time periods, and stores and counts the received reservation information to obtain the reservation order data for each time period. A reservation order threshold can be set. If the number of reservation orders exceeds this threshold, it can be judged that the unit time period is in the peak period for battery swapping. Otherwise, it is not the peak period for battery swapping.

[0086] On the basis of determining the peak period of battery swapping, the starting time information of the second stage is determined based on the starting time of the peak period of battery swapping and the charging duration of the second stage, wherein the starting time information of the second stage is the time difference between the starting time of the peak period of battery swapping and the starting time of the peak period of battery swapping, which is greater than or equal to the charging duration of the second stage.

[0087] S240: Based on the start time information of the second stage, control the charging of the battery to be charged to perform the second stage.

[0088] For example, when the battery swap is in the idle stage and there is no demand for battery swap, a small rate of charging, that is, constant current 0.3C charging to 50% storage can be used, and subsequent charging above 50% SOC can be charged in advance based on the estimated time of 0.3C charging. Relatively speaking, if the battery swap is busy and the demand for battery swap is at a peak, a large rate of fast charging, constant current 1.2C fast charging, can be used to meet actual operational needs.

[0089] In the technical solution of this embodiment, based on the battery swap demand information obtained by the battery swap station, including historical battery swap demand, swap point reservation order and other information, it is analyzed through the prediction model to obtain the peak battery swap period and the predicted peak battery swap period, and then the start time of the second stage is obtained to control the start and end of the second stage of the battery to be charged. This method can help the battery swap station complete the charging and scheduling of the battery to be charged, so that users can complete the vehicle battery swap without waiting too long.

[0090] Embodiment 3

[0091] Figure 3 This is a flow chart of a battery charging method provided in the third embodiment of the present invention. This embodiment optimizes the method based on the above embodiment. Optionally, based on the charging consumption information at each moment, the starting time information of the second stage of the battery to be charged is determined. According to the charging consumption information at each moment, at least one charging time period with the lowest total consumption is determined; the starting time information of the charging time period is used to determine the starting time information of at least one sub-stage in the second stage; and the charging rate is determined according to the charging amount of the second stage and the charging duration of at least one charging time period; based on the starting time information and the charging rate of at least one sub-stage, the second stage charging of the battery to be charged is controlled. Figure 3 As shown, the method includes:

[0092] S310: For a battery to be charged, control the battery to be charged to perform a first stage of charging.

[0093] S320: When the power level of the battery to be charged meets the storage power condition, the first stage of charging is terminated.

[0094] S330: Determine the start time information of the second stage of the battery to be charged based on the charging consumption information at each moment.

[0095] Optionally, based on the charging consumption information at each moment, at least one charging time period with the lowest total consumption is determined as at least one sub-stage in the second stage.

[0096] The total consumption can be specifically understood as the total amount consumed when the battery to be recharged is fully charged. Since there are certain differences in charging consumption information at different times, the charging consumption during the peak charging period is generally higher than that during other periods. The lowest total consumption can be specifically understood as the least electricity cost required to fully charge the battery to be recharged. According to the different charging consumption information at each time, the charging period of the second stage can also be divided into multiple charging periods.

[0097] Specifically, the amount of electricity required to fully charge the battery to be charged can be obtained by the difference between the battery capacity of the battery to be charged and the remaining power of the battery. An appropriate charging power is selected to charge the battery. The difference between the battery capacity and the remaining power of the battery is divided by the charging power to obtain the charging time. The charging time is multiplied by the charging consumption information at each moment, and the result is the total consumption of the battery to be charged. The charging consumption of the battery to be charged at different time periods can be calculated by a calculation model to obtain the time period with the lowest consumption, wherein there is at least one time period with the lowest consumption.

[0098] Optionally, the start time information of at least one sub-stage in the second stage is determined based on the start time information of the charging period; and the charging rate is determined according to the charging amount of the second stage and the charging duration of at least one charging period.

[0099] Among them, the charging rate can be specifically understood as a measure of charging speed, which refers to the current value required for the battery to be charged to its rated capacity within a certain period of time, that is, charging rate = charging current / battery rated capacity. The rated capacity of the battery can be obtained by identifying the battery identification device in the control system of the battery swap station. The sub-stage can be specifically understood as part of the charging period in the second stage of charging or the entire charging period.

[0100] Specifically, the charging period of the second stage can be set into multiple sub-stages according to the different consumption information at each moment. The starting time of the first sub-stage can be at least determined by the starting information of the charging period, that is, the starting time of the charging period is the starting time of the first sub-stage. The charging amount of the second stage is determined by the difference between the battery capacity of the battery to be charged and the remaining power of the battery to be charged. The charging time of the second stage is obtained according to the charging consumption information and the charging amount, and then the charging current information of the second stage is obtained. The charging rate is determined according to the formula charging rate = charging current / battery rated capacity.

[0101] S340: Based on the start time information and the charging rate of at least one sub-stage, control the charging of the battery to be charged to perform the second stage.

[0102] Specifically, the battery charging control system performs the second stage charging operation on the battery to be charged according to the obtained charging multiple and starting time, and stops charging after the battery is fully charged.

[0103] On the basis of the above embodiments, based on the battery swapping demand of the battery swapping station and / or the charging consumption information at each moment, the starting time information of the second phase of the battery to be charged is determined, and it also includes: determining the peak battery swapping period in the battery swapping demand of the battery swapping station; within the rechargeable period between the current moment and the peak battery swapping period, according to the charging consumption information at each moment, determining at least one charging period with the lowest total consumption, and using the starting time information of the charging period to determine the starting time information of at least one sub-phase in the second phase.

[0104] Specifically, the peak period of battery replacement is first determined through the battery replacement demand received by the battery replacement station. In the rechargeable time period between the current time and the peak period of battery replacement, the time period with the lowest total consumption in the rechargeable time period is obtained based on the charging consumption information at each time obtained, and there is at least one such time period. By obtaining the time period with the lowest total consumption, the starting time of the charging time period is obtained, and this starting time can be used as the starting time of the second stage of charging, wherein the second stage includes at least one sub-stage, and then the starting time of the charging time period is the starting time information of at least one sub-stage in the second stage.

[0105] In this embodiment, the battery swapping demand received by the battery swapping station is combined with the charging consumption information at each time, and the charging time period between the peak battery swapping period and the current time and the peak battery swapping period is determined to obtain the minimum consumption time period within the charging time period, and the start time of at least one sub-stage in the second stage is obtained based on the above information. In this way, part or even all of the charging process in the second stage can be completed during the non-peak time period, effectively reducing the charging consumption required to fully charge the battery to be charged.

[0106] In the technical solution of this embodiment, based on the acquired charging consumption information, the start time and charging rate of the second stage are obtained through the calculation model and the battery replacement prediction model. Since the consumption information at different charging moments is different, the second stage is divided into multiple sub-stages to perform the charging task, which can reduce the charging consumption while ensuring that the battery to be charged can be fully charged in time. This charging method not only ensures battery safety but also reduces charging costs.
