Example one
Fig. 1 is a flowchart of a battery charging management method according to an embodiment of the present invention, which is applicable to a situation where a charging process of a vehicle battery is reasonably distributed, and the method may be executed by a battery charging management apparatus, which may be implemented in the form of hardware and/or software, and the battery charging management apparatus may be configured in a terminal and/or a server. As shown in fig. 1, the method includes:
and S110, obtaining a historical charging log of the target battery in at least one battery replacement station.
In the present embodiment, the target battery may be a vehicle battery that requires charge process management. Optionally, the target battery may be any battery in the battery replacement station, and may also be any battery in the battery replacement station. Illustratively, the target battery may be a lithium iron phosphate battery, a ternary battery, a lead-acid battery, or the like. The battery swapping stations can be all battery swapping stations for realizing a charging process for the target battery. The historical charging log can be used for representing the charging condition of the target battery at the current charging station. The historical charging log comprises at least one piece of charging record data. For example, when the target battery is charged, the time corresponding to the start of charging may be used as the record basis of the first piece of charging record data in the charging log, and the time is recorded every 1 minute until the time when charging is completed is used as the record basis of the last piece of charging record data in the charging log; or, the remaining capacity of the target battery at the beginning of charging may be used as a record basis for the first charging record data in the charging log, and each time 0.1% of the charged capacity is recorded, until the remaining capacity at the end of charging is used as a record basis for the last charging record data in the charging log.
In practical application, when the target battery is charged in each power conversion station, in order to analyze the charging process of the target battery subsequently, the whole charging process of the target battery is recorded, and historical charging logs are generated, wherein each historical charging log comprises all charging record data in the charging process.
The charging record data can be understood as record data generated when the target battery is charged in the current charging pile, and at least one piece of charging record data in the historical charging log corresponds to the charging time when the target battery is charged, namely each piece of charging record data corresponds to one charging time in the charging process. Optionally, each piece of charging record data includes current battery data of the target battery and charging pile data when the target battery is charged.
It should be noted that, the charging record data in the historical charging log are sequentially recorded according to the charging time, may be recorded once at intervals, may be continuously recorded in the charging process, and the like, and when the historical charging log is analyzed, the charging record data corresponding to the preset variation threshold value when the charging amount of the target battery changes is required to be obtained, for example, the preset variation threshold value is 1%, that is, the charging record data corresponding to the target battery when the charging amount of the target battery every time is 1% is required to be obtained. The advantages of acquiring the charging record data in the above manner are that: because the historical charging log comprises a plurality of charging record data, each charging stage in the whole charging process is divided conveniently, and the charging efficiency of the target battery in each charging stage when the current charging pile is charged or other data for evaluating the charging process and the like are determined conveniently, each piece of charging record data can be obtained according to the method that the electric quantity charged by the target battery each time reaches the preset variation threshold.
Optionally, the current battery data includes a cell temperature, a cell voltage, a battery state of charge, and a battery health degree corresponding to the current charge amount; the charging pile data includes a charging voltage and/or a charging current when the target battery is charged.

Among them, the unit cell is a basic unit constituting the secondary battery pack, and its rated voltage is usually 2 volts.
In the present embodiment, the cell temperature may be understood as heat generated during charging of each of the target batteries. The single battery temperature in the current battery data comprises the highest single battery temperature and the lowest single battery temperature. The cell voltage may be understood as a voltage of each cell in the target battery during the charging process. The cell voltage in the current battery data includes a highest cell voltage and a lowest cell voltage. The State of Charge (SOC) of the battery may be used to reflect the remaining capacity of the battery, and may be a ratio of the remaining capacity of the battery to the total capacity of the battery, usually expressed as a percentage. The State of Health (SOH) of a battery may be understood as a percentage of the current capacity of the battery to the factory capacity. Battery health may be used to characterize the current battery's ability to store electrical energy. The health of the battery is gradually reduced along with the use time of the battery, and the reduction trend of the health of the battery is related to the use condition and the charging condition of the battery. The charging voltage can be understood as the charging voltage of the target battery when the charging post is charging. The charging current may be a charging current of the target battery when the charging pile is charging.
Specifically, when the charging process of the battery needs to be adjusted so that the battery can be charged within a target time length, historical charging logs of the target battery at each power conversion station can be obtained, and the charging strategy of the target battery is determined by analyzing each historical charging log.
And S120, determining charging variation data and charging management attributes corresponding to the target battery in at least one charging stage according to the historical charging log of the at least one battery replacement station.
In practical applications, when a battery is charged, due to various chemical changes, electrochemical changes, material transport, and the like generated inside the battery during the charging process, the charging process is usually divided into a plurality of charging stages, and each charging stage corresponds to a different charging voltage and charging current. For example, the charging phase of the storage battery may include a constant current charging phase, a constant voltage charging phase and a floating charge phase.
In this embodiment, the charge variation data may include a charge variation electric quantity and a charge variation time length, that is, a time length required for each unit change in the state of charge of the target battery during the charging process and a charged electric quantity. The charge management attributes may be understood as data information required for achieving a reasonable distribution of the charging process of the target battery. Optionally, the charging management attribute includes an average charging voltage, an average charging current, an average temperature of the single battery, and an average voltage of the single battery corresponding to the corresponding charging phase. The average charging voltage may be an average charging voltage value of the charging pile when the charging pile charges the target battery in the current charging stage. The average charging current may be an average charging current value of the charging pile when the charging pile charges the target battery in the current charging stage. The average cell temperature may be an average of the cell temperatures of the cells in the target battery in the current charging phase. The average cell voltage may be an average of the cell voltages of the cells in the target battery in the current charging phase.
Specifically, after the historical charging logs of the target battery at each battery swapping station are obtained, the historical charging logs corresponding to each battery swapping station are analyzed, charging variation data and corresponding charging management attributes corresponding to the target battery at each charging stage are determined, and charging management is performed on the target battery according to the determined data information.
And S130, determining a charging strategy of the target charging pile when the target battery is charged based on the charging variable quantity data corresponding to each charging stage and the corresponding charging management attribute, so as to charge the target battery based on the charging strategy.
In this embodiment, the target charging pile may be a charging device that charges a target battery. The charging strategy can be a charging operation flow of the target battery when the current charging pile is charged. And different charging strategies corresponding to the charging of the target battery on different charging piles are adopted.
Optionally, the determining a charging policy of the target charging pile when the target battery is charged based on the charging variation data corresponding to each charging stage and the corresponding charging management attribute includes: aiming at each charging stage, determining average charging variation data corresponding to the current charging stage based on the charging variation data corresponding to the current charging stage; and determining a charging strategy of the target charging pile when the target battery is charged based on the average charging variation data corresponding to each charging stage and the corresponding charging management attribute.
In this embodiment, the average charge variation data may include an average charge time period and an average charge amount.
Specifically, for each charging stage in the charging process of the target battery, the charging variation data corresponding to the current charging stage is subjected to mean processing, the average charging variation corresponding to the current charging stage is determined, and further, according to the average charging variation data corresponding to each charging stage and the corresponding charging management attribute, the charging operation flow of the target battery in the target charging pile can be determined, so that the target battery is charged according to the determined charging operation flow.
According to the technical scheme, the charging method comprises the steps of obtaining a historical charging log of a target battery in at least one charging station, further determining charging variation data and charging management attributes corresponding to the target battery in at least one charging stage according to the historical charging log of the at least one charging station, and finally determining a charging strategy of a target charging pile when the target battery is charged based on the charging variation data and the corresponding charging management attributes corresponding to the charging stages so as to charge the target battery based on the charging strategy.
