[0028] Embodiment 1

[0029] Figure 1 A flowchart of a battery replacement method is provided for the first embodiment of the present invention. This embodiment is applicable to the situation where the battery power in the battery replacement station is insufficiently charged for multiple times, resulting in a battery power problem. The method can be performed by a battery replacement device, which can be implemented in the form of hardware and / or software, and can be configured in a terminal and / or server. Figure 1 As shown, the method includes:

[0030] S110. When a battery replacement request of a target battery is received, historical battery replacement data of the target battery is obtained, and a historical state of charge value is determined based on the historical battery replacement data.

[0031] In this embodiment, the target battery can be any battery in the battery swap station. The battery swap request can be a request for battery swap use of the target battery by a vehicle to be swapped at the battery swap station. The historical battery swap data can be the charging record, battery swap record and other data used to characterize the battery status of the target battery. The historical state of charge value can be the state of charge value of the target battery when it is charged and swapped within a certain period of time in history. Among them, the state of charge value is the ratio of the remaining capacity of the battery to its capacity in a 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 and battery balancing of the entire vehicle.

[0032] In the specific implementation, when the terminal equipment of the battery swap station receives a battery swap request for the target battery from the vehicle to be swapped, in order to determine whether the target battery meets the battery swap conditions, the historical battery swap data of the target battery is obtained and analyzed, so as to determine the charging and swapping status of the target battery in the past period of time and the charge state value during charging and swapping based on the acquired historical battery swapping data.

[0033] S120. Determine a target battery replacement strategy for the target battery based on historical state of charge values.

[0034] In this embodiment, the target battery replacement strategy can be a pre-set battery replacement operation process for determining the battery replacement operation process according to the status of each battery in the battery replacement station. Optionally, the target battery replacement strategy includes a normal battery replacement process and a short process correction process. Among them, the short process correction process can be an operation process for charging the target battery with a small current. Exemplarily, the normal battery replacement process can be to perform normal battery replacement processing or reserve processing on the target battery.

[0035] In the specific implementation, after obtaining the historical battery replacement data of the target battery and determining the historical state of charge value based on the historical battery replacement data, the specific battery replacement processing method of the target battery is determined by analyzing the historical state of charge value of the target battery in the past period of time, so that the target battery can be processed according to the determined processing method. The advantage of this setting is that different battery replacement processing strategies can be selected by judging the state of the battery, thereby achieving the effect of improving the operation rate of the battery replacement station.

[0036] S130. Process the target battery according to the target battery replacement strategy.

[0037] In a specific implementation, after the target battery replacement strategy is determined by analyzing the historical state of charge value of the target battery, the target battery is processed according to the determined target battery replacement strategy.

[0038] The technical solution of the embodiment of the present invention is to obtain the historical battery replacement data of the target battery when a battery replacement request of the target battery is received, determine the historical state of charge value based on the historical battery replacement data, and then determine the target battery replacement strategy of the target battery based on the historical state of charge value, wherein the target battery replacement strategy includes a normal battery replacement process and a short process correction process. Finally, the target battery is processed according to the target battery replacement strategy, which solves the problem of rapid battery power loss and shortened service life of the battery in the prior art due to multiple charging and battery replacement operations without being fully charged, and may also cause the vehicle to suddenly break down while using the battery. Different battery replacement strategies are selected according to the actual state of the battery to achieve the effect of battery replacement correction, thereby improving the operating efficiency of the battery replacement station.

[0039] Embodiment 2

[0040] Figure 2 This is a flow chart of a battery replacement method provided in Embodiment 2 of the present invention. This embodiment is a refinement of S120 in the above embodiment. Figure 2 As shown, the method includes:

[0041] S210. When a battery replacement request of a target battery is received, historical battery replacement data of the target battery is obtained, and a historical state of charge value is determined based on the historical battery replacement data.

[0042] S220. When the historical state of charge values ​​within the preset battery replacement number threshold in the historical battery replacement data do not reach 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 threshold, the target battery replacement strategy is determined as the short process correction process.

[0043] In this embodiment, the preset battery replacement times threshold may be a pre-set maximum number of battery replacement times for judging the charging and replacement status of the target battery in the past period of time. Exemplarily, the preset battery replacement times threshold 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 pre-set judgment standard value for judging the battery replacement 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 true value of the state of charge may be the state of charge value that the target battery should currently have, determined by the target battery according to its battery characteristics and the calculation algorithm. The state of charge display value may be the value actually displayed on the display interface when the target battery is applied. The preset difference threshold may be a pre-set difference value for judging whether the target battery needs charging correction processing. Exemplarily, the preset difference threshold may be 10%, 20% or 30%, etc. In order to more clearly illustrate the implementation method of the above steps, specific examples can be used for illustration. For example, when determining the battery replacement strategy of the target battery, it is first necessary to determine through the historical battery replacement data of the target battery whether the historical state of charge values ​​of the target battery in the last five battery replacements have not reached 95%, 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 20%. If the above judgment conditions are all met, the target battery replacement strategy of the target battery can be determined as a short process correction process.

[0044] Optionally, based on the above implementation, the method further includes: determining the actual state of charge value and the state of charge display value of the target battery according to the battery management system of the target battery.

[0045] Among them, the battery management system (BMS) can be a terminal monitoring and management system for 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, extend the battery life, monitor the battery status, etc.

[0046] In practical applications, when it is necessary to determine the battery replacement strategy of the target battery, the actual 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 target battery can be judged based on the obtained state of charge value.

[0047] S230. Process the target battery according to the target battery replacement strategy.

[0048] Generally speaking, if it is determined through the charge state value of the target battery that the target battery needs charging correction, the target battery replacement strategy can be determined as a short-process correction process, and the target battery can be processed by implementing the short-process correction process.

[0049] Optionally, the target battery is processed according to the target battery replacement strategy, including: when the actual 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; determining the charging current of the target voltage according to the rated capacity of a first preset ratio, and charging the target battery according to the charging current; when the charging voltage of the target battery reaches the cut-off voltage, gradually reducing the charging current and continuing to charge the target battery until the charging voltage of the target battery reaches the cut-off voltage again.

[0050] Among them, the second preset state of charge threshold value can be a pre-set state of charge value used to determine the target battery in the charging correction method of the short process correction process. Exemplarily, the second preset state of charge threshold value can be 85%, 90% or 95%, etc. The rated capacity of the target battery can 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 current allowed to discharge will also increase accordingly. The cut-off voltage of the target battery can be the termination voltage, that is, when the battery is discharged, the voltage drops to the minimum operating voltage value at which the battery is not suitable for further discharge. Different battery types and different discharge conditions will also have different cut-off voltages. Exemplarily, the cut-off voltage of lithium iron phosphate batteries is 3.65 volts, and the cut-off voltage of ternary batteries is 4.2 volts. The first preset ratio can be a pre-set ratio parameter used to determine the charging current of the target battery when performing short process correction. Exemplarily, the first preset ratio can be 0.1, 0.2 or 0.3, etc.

[0051] In order to more clearly introduce the implementation method of this step, it can be illustrated by a specific example. For example, when the target battery is processed according to the short process correction process, first, determine whether the actual value of the charge state of the target battery reaches 90%. If it reaches, determine the rated capacity and cut-off voltage of the target battery. When the target battery is charged and calibrated, first determine the charging current of the target battery to 0.2 times the rated capacity. When the rated capacity is 10 amperes, the charging current is 2 amperes. Charge to the cut-off voltage of the target battery according to the above charging current, and then, based on the above charging current, reduce the charging current to 80% of the original value, charge again and charge to the cut-off voltage, and then reduce the charging current to 80% of the original value until the charging current drops to 0.1 times the rated capacity. Charge to the cut-off voltage according to the charging current to complete the entire charging correction process.

[0052] Optionally, the target battery is processed according to the target battery replacement strategy, including: when the actual state of charge value of the target battery does not reach a second preset state of charge threshold, the target battery is processed using a normal charging method until the actual state of charge value is greater than or equal to a third preset state of charge threshold.

[0053] The third preset state of charge threshold value may be a pre-set state of charge value used to determine whether the target battery has completed the current charging process. For example, the third preset state of charge value may be 85%, 90% or 95%.

[0054] In actual applications, by analyzing the actual state of charge of the target battery and determining that it has not reached the second preset state of charge threshold, the target battery can be charged using a normal fast charging method until the actual state of charge of the target battery is greater than or equal to the state of charge value used to determine whether it is fully charged.

[0055] On the basis of the above technical solution, optionally, before processing the target battery according to the target battery replacement strategy, it also includes: determining whether the battery replacement station where the target battery is located has a spare battery; if so, processing the target battery according to the short process correction process.

[0056] Generally, before charging or swapping the target battery through the short-process calibration process, since the calibration process consumes a long time, in order to ensure that the operating efficiency of the battery swap station where the target battery is located is not affected, you can first use the battery monitoring and management system of the battery swap station to determine whether there is a spare battery that can provide charging or swapping services. If so, the spare battery can temporarily replace the target battery for charging or swapping services, so that the target battery can be processed according to the short-process calibration process.

[0057] Optionally, before processing the target battery according to the target battery replacement strategy, it also includes: if not, adjusting the charge state display value of the target battery to the actual charge state value and recording it.

[0058] In actual applications, if the current battery swap station does not have a spare battery and is in urgent need of operation, the charge status display value of the target battery can be adjusted to the actual charge status value, and the adjustment is recorded at the same time, so that the user can timely understand the power status of the target battery and take corresponding response strategies to avoid the situation where the vehicle suddenly breaks down when using the target battery for driving.

[0059] The technical solution of the embodiment of the present invention is to obtain the historical battery replacement data of the target battery when a battery replacement request of the target battery is received, determine the historical state of charge value according to the historical battery replacement data, and then, when the historical state of charge values ​​within the preset battery replacement number threshold in the historical battery replacement data 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 threshold, determine the target battery replacement strategy as a short process correction process, and finally, process the target battery according to the target battery replacement strategy, so as to solve the problem of fast battery power loss and shortened service life caused by multiple charging and battery replacement operations without full charge in the prior art, and also cause the vehicle to suddenly break down while using the battery for driving, so as to realize the effect of battery replacement correction by selecting different battery replacement strategies according to the actual state of the battery, and improve the operating efficiency of the battery replacement station.
