Example 1

FIG. 1 is a flowchart of a method for battery swapping provided in Embodiment 1 of the present invention. This embodiment can be applied to the situation that the battery in the battery swapping station is not fully charged for many times, and the battery power problem occurs. It is performed by a battery swapping device, which may be implemented in the form of hardware and/or software, and may be configured in a terminal and/or a server. As shown in Figure 1, the method includes:

S110. When a power exchange request of the target battery is received, obtain historical power exchange data of the target battery, and determine a historical state of charge value according to the historical power exchange data.

In this embodiment, the target battery can be any battery in the swap station. The power swap request may be a power swap request for the target battery of the vehicle to be swapped at the power swap station. The historical power exchange data can be the charging record of the target battery, the power exchange record, and other data used to characterize the state of the battery. The historical state of charge value may be the state of charge value of the target battery when the target battery is charged and exchanged within a certain period of history. Among them, the state of charge value is the ratio of the remaining capacity of the battery to the capacity of the fully charged state. In practical applications, the state of charge value of the battery is one of the important parameters of the battery management system, and it is also the basis for the charging and discharging control strategy of the entire vehicle and the battery balancing work.

In a specific implementation, when the terminal device of the power swap station receives a power swap request for the target battery from the vehicle to be swapped, in order to determine whether the target battery meets the power swap conditions, the historical power swap data of the target battery is obtained and analyzed, thereby According to the acquired historical power exchange data, the charging and exchanging situation of the target battery in the past period of time and the state of charge value during charging and exchanging are determined.

In a specific implementation, after obtaining the historical power exchange data of the target battery and determining the historical state of charge value according to the historical power exchange data, the historical state of charge value of the target battery in the past period of time is analyzed to determine the value of the target battery. The specific battery replacement processing method, so that the target battery can be processed according to the determined processing method. The advantage of this setting is that different power exchange processing strategies can be selected by judging the state of the battery, so that the effect of improving the operation rate of the power exchange station can be achieved.

Embodiment 2

FIG. 2 is a flowchart of a method for replacing a battery according to Embodiment 2 of the present invention. This embodiment is a refinement of S120 in the foregoing embodiment. As shown in Figure 2, the method includes:

S210. When a power exchange request of the target battery is received, obtain historical power exchange data of the target battery, and determine a historical state-of-charge value according to the historical power exchange data.

S220. When the historical state-of-charge values within the preset battery-change times threshold in the historical battery-exchange data do not reach the first preset state-of-charge threshold, and the actual state-of-charge value of the target battery is between the state-of-charge display value When the difference is greater than or equal to the preset difference threshold, the target battery swapping strategy is determined as a short-process correction process.

In this embodiment, the preset threshold for the number of battery swaps may be a preset maximum value for the number of battery swaps used for judging the charging and swapping state of the target battery in the past period of time. Exemplarily, the preset threshold for the number of battery swaps may be 3 times, 4 times, or 5 times, etc., which is not limited in this embodiment. The first preset state-of-charge threshold may be a preset judgment standard value used for judging the power exchange strategy of the target battery. Exemplarily, the first preset state of charge value may be 85%, 90%, or 95%, etc., which is not limited in this embodiment. The real state of charge value may be the state of charge value that the target battery should have at present, determined according to its battery characteristics and the calculation algorithm. The display value of the state of charge may be the value actually displayed on the display interface when the target battery is applied. The preset difference threshold may be a preset difference used for judging whether the target battery needs to be charged and corrected. Exemplarily, the preset difference threshold may be 10%, 20%, or 30%. In order to illustrate the implementation of the above steps more clearly, a specific example can be used to illustrate. For example, when determining the power exchange strategy of the target battery, it is first necessary to determine whether the target battery has been replaced for the past five times through the historical power exchange data of the target battery. The historical state-of-charge values at the time of the test do not reach 95%, and the difference between the real state-of-charge value of the target battery and the state-of-charge display value is greater than or equal to 20%. If the above judgment conditions are all satisfied, the target battery can be The target battery replacement strategy is determined as a short-process correction process.

Optionally, on the basis of the above embodiment, the method further includes: determining the real state of charge value and the displayed state of charge value of the target battery according to the battery management system of the target battery.

The battery management system (Battery Management System, BMS) may be a terminal monitoring and management system of the target battery. The battery management system is mainly used to intelligently manage and maintain each battery unit, prevent the battery from overcharging and overdischarging, prolong the service life of the battery, and monitor the status of the battery.

In practical applications, when the battery replacement strategy of the target battery needs to be determined, the real state of charge value and the state of charge display value of the target battery can be obtained through the battery management system of the target battery, so that the obtained state of charge value can be used for The target battery is judged.

S230. Process the target battery according to the target battery swapping strategy.

In general, if it is determined that the target battery needs to be charged and corrected after judging the state of charge value of the target battery, the target battery replacement strategy can be determined as a short-process correction process, and the target battery can be adjusted by implementing the short-process correction process. to be processed.

Optionally, processing the target battery according to the target battery swapping strategy includes: when the real value of the state of charge of the target battery reaches a second preset state of charge threshold, determining the rated capacity and cut-off voltage of the target battery; The rated capacity of the preset ratio determines the charging current of the target voltage, and charges the target battery according to the charging current; when the charging voltage of the target battery reaches the cut-off voltage, gradually reduce the charging current and continue to charge the target battery until the target battery is fully charged. The charging voltage reaches the cutoff voltage again.

The second preset state-of-charge threshold may be preset and used to determine the state-of-charge value of the charging correction method of the target battery in the short-process correction process. Exemplarily, the second preset state-of-charge threshold may be 85%, 90%, or 95%, or the like. The rated capacity of the target battery may be the battery capacity that the target battery can actually output. The larger the rated capacity, the larger the volume of the battery, and the larger the current allowed to discharge. The cut-off voltage of the target battery can be the termination voltage, that is, when the battery is discharging, the voltage drops to the lowest working voltage value that the battery should not continue to discharge. Different battery types and different discharge conditions have different cut-off voltages. Exemplarily, the cut-off voltage of the lithium iron phosphate battery is 3.65 volts, and the cut-off voltage of the ternary battery is 4.2 volts. The first preset ratio may be preset, and is used to determine the ratio parameter of the charging current of the target battery when the short-process correction is performed. Exemplarily, the first preset ratio may be 0.1, 0.2, or 0.3, or the like.

In order to introduce the implementation of this step more clearly, a specific example can be used to illustrate. For example, when the target battery is processed according to the short-process calibration process, first, it is determined whether the real value of the state of charge of the target battery reaches 90%. , if it is reached, determine the rated capacity and cut-off voltage of the target battery. When charging and correcting the target battery, first determine the charging current of the target battery to be 0.2 times the rated capacity. When the rated capacity is 10 amps, the charging current is It is 2 amps, charged to the cut-off voltage of the target battery according to the above charging current, and then, on the basis of the above charging current, the charging current is reduced to 80% of the original, charged again and charged to the cut-off voltage, and then the charging current is Reduce to 80% of the original value until the charging current is reduced to 0.1 times the rated capacity, and then charge to the cut-off voltage according to the charging current to complete the entire charging correction process.

Optionally, processing the target battery according to the target battery swapping strategy includes: when the real value of the state of charge of the target battery does not reach the second preset state of charge threshold, processing the target battery by using a normal charging method until The real state of charge value is greater than or equal to the third preset state of charge threshold.

The third preset state of charge threshold may be a preset state of charge value used to determine whether the target battery has completed the current charging process. Exemplarily, the third preset state of charge value may be 85%, 90%, or 95%, or the like.

In practical applications, by analyzing the real value of the state of charge of the target battery and determining that it does not reach the second preset state of charge threshold, the target battery can be charged by a normal fast charging method until the target battery is fully charged. The real state of charge value is greater than or equal to the state of charge value used to determine whether it is fully charged.

On the basis of the above technical solution, optionally, before processing the target battery according to the target battery swap strategy, the method further includes: determining whether the battery swap station where the target battery is located has a backup battery; target battery for processing.

In general, before charging and replacing the target battery through the short-process calibration process, since the calibration process consumes a long time, in order to keep the operation efficiency of the swap station where the target battery is located, the The battery monitoring and management system determines whether there is a backup battery that can provide charging and replacing services. If there is, the backup battery can temporarily replace the target battery for charging and replacing services, so that the target battery can be processed according to the short-process correction process.

Optionally, before processing the target battery according to the target power exchange strategy, the method further includes: if not, adjusting the displayed value of the state of charge of the target battery to the real value of the state of charge and recording it.

In practical applications, if there is no spare battery in the current swap station that needs to be operated urgently, the displayed value of the state of charge of the target battery can be adjusted to the real value of the state of charge, and this adjustment can be recorded at the same time, so that the user can know the target battery in time. and take corresponding countermeasures to avoid the sudden breakdown of the vehicle when using the target battery for driving.

According to the technical solution of the embodiment of the present invention, when a power exchange request of the target battery is received, the historical power exchange data of the target battery is obtained, the historical state of charge value is determined according to the historical power exchange data, and then, when the historical power exchange data is predicted It is assumed that the historical state-of-charge values within the threshold for the number of battery swaps are all greater than the first preset state-of-charge threshold, and the difference between the actual state-of-charge value of the target battery and the state-of-charge display value is greater than or equal to the preset difference value When the threshold is reached, the target battery swapping strategy is determined as a short-process correction process, and finally, the target battery is processed according to the target battery swapping strategy, which solves the problem that the battery in the battery swapping station in the prior art is charged and swapped because it is not fully charged for many times. As a result, the battery loses power quickly and the service life is shortened, and it will also cause the vehicle to suddenly break down on the way to use the battery. The effect of battery replacement correction improves the operational efficiency of the battery replacement station.
