Example 1
Fig. 1 is a flowchart of a battery charging management method according to an embodiment of the present invention, where the method may be implemented by a battery charging management device, and the battery charging management device may be implemented in hardware and/or software, and the battery charging management device may be configured in a terminal and/or a server. As shown in fig. 1, the method includes:

In the present embodiment, the target battery may be a vehicle battery that needs to be subjected to charging process management. Optionally, the target battery may be any battery in the power exchange station, and may also be any battery in the power exchange station. By way of example, the target battery may be a lithium iron phosphate battery, a ternary battery, a lead acid battery, or the like. The station may be all stations that carry out the charging process for the target battery. The historical charge log may be used to characterize the charge of the target battery at the current battery exchange station. The historical charging log comprises at least one piece of charging record data. For example, when charging the target battery, the time corresponding to the start of charging may be used as the recording basis of the first charging record data in the charging log, and each charging is performed for 1 minute until the time when the charging is completed is used as the recording basis of the last charging record data in the charging log; or, the remaining capacity of the target battery at the beginning of charging can be used as the recording basis of the first piece of charging record data in the charging log, and the recording of the 0.1% capacity is performed every time until the remaining capacity at the end of charging is used as the recording basis of the last piece of charging record data in the charging log.
In practical application, when the target battery is charged at each power exchange station, in order to analyze the charging process of the target battery subsequently, the whole charging process of the target battery is recorded, and a historical charging log is generated, wherein each historical charging log comprises all charging record data in the charging process.
The charging record data may be understood as record data generated when the target battery is charged in the current charging pile, and at least one charging record data in the historical charging log corresponds to a charging time when the target battery is charged, that is, each 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 charge record data in the history charge log may be sequentially recorded according to the charging time, may be recorded at intervals, may be continuously recorded during the charging process, or the like, and when the history charge log is analyzed, it is required to obtain the charge record data corresponding to each change of the charge amount of the target battery by a preset change amount threshold, for example, taking the preset change amount threshold as 1% as an example, that is, it is required to obtain the charge record data corresponding to each change of the charge amount of the target battery by 1%. The benefit of acquiring charging record data in the above manner is that: because the historical charging log comprises a plurality of pieces of charging record data, in order to conveniently divide each charging stage in the whole charging process, and in order to conveniently determine the charging efficiency of the target battery in each charging stage when the current charging pile charges or other pieces of data used for evaluating the charging process, and the like, each piece of charging record data can be obtained according to a method that the electric quantity of the target battery charged each time reaches a preset variation threshold value.
Optionally, the current battery data includes a cell temperature, a cell voltage, a cell state of charge, and a cell health corresponding to the current charge amount; the charging post data includes a charging voltage and/or a charging current when charging the target battery.

The individual cells are the basic units that form the battery pack, and their rated voltage is usually 2 volts.
In the present embodiment, the cell temperature may be understood as the heat generated during charging of each cell in the target battery. The battery cell temperature in the current battery data comprises a highest battery cell temperature and a lowest battery cell temperature. The cell voltage may be understood as the voltage of each cell in the target battery during charging. The cell voltages in the current cell data include the highest cell voltage and the lowest cell voltage. The State of Charge (SOC) of the battery may be used to reflect the remaining power of the battery, and the value may be a ratio of the remaining power of the battery to the total power of the battery, which is generally expressed as a percentage. The State of Health (SOH) can 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 battery health gradually decreases as the battery usage time increases, and the decrease trend is related to the battery usage and charging condition. The charging voltage may be understood as a charging voltage of the target battery when the charging pile is charged. The charging current may be a charging current of the target battery when the charging pile is charged.
Specifically, when the charging process of the battery needs to be adjusted so that the battery can be charged within the target duration, the historical charging logs of the target battery in each battery exchange station can be obtained, and the charging strategy of the target battery is determined by analyzing each historical charging log.
And S120, according to the historical charging log of at least one battery replacement station, determining charging variation data and charging management attributes corresponding to the target battery in at least one charging stage.
In practical applications, when a battery is charged, the charging process is generally divided into a plurality of charging phases, each of which corresponds to a different charging voltage and charging current, due to various chemical changes, electrochemical changes, substance transmission, etc. generated in the battery during the charging process. Illustratively, taking a storage battery as an example, the charging phases thereof may include a constant current charging phase, a constant voltage charging phase, and a float charging phase.
In this embodiment, the charging variable data may include a charging variable power amount and a charging variable duration, that is, a duration required by each unit change of the battery state of charge of the target battery in the charging process, and a charged power amount. The charge management attribute may be understood as data information required for achieving reasonable distribution of the charging process of the target battery. Optionally, the charge management attribute includes an average charge voltage, an average charge current, an average cell temperature, and an average cell voltage corresponding to the respective charge phases. The average charging voltage may be an average charging voltage 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 of the charging post when charging the target battery at the current charging stage. The cell average temperature may be an average of cell temperatures of the cells in the target cell during the current charging stage. The cell average voltage may be an average of cell voltages of the cells in the target cell in the current charging stage.
Specifically, after the historical charging logs of the target battery in each battery exchange station are obtained, the historical charging logs corresponding to each battery exchange station are analyzed, charging variable quantity data and corresponding charging management attributes corresponding to the target battery in 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 variation 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 stake may be a charging device that charges the target battery. The charging policy may be a charging operation flow of the target battery when the current charging pile is charging. And when the target battery is charged on different charging piles, different charging strategies are corresponding to the target battery.
Optionally, determining the charging policy of the target charging post when charging the target battery based on the charging variation data corresponding to each charging stage and the corresponding charging management attribute includes: for 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.
