[0214] Scheme 27. A battery swap station, wherein the battery swap station is provided with the control device of scheme 26.

[0215] As understood by those skilled in the art, the battery charging method of the battery swap station of the present application determines whether there is a battery that needs to be swapped in a battery compartment group based on battery state information. When there is a battery that needs to be swapped in a battery compartment group, the battery is swapped in a battery compartment group based on a flexible charging strategy. The battery swap station can swap the battery in a battery compartment group, so that the charging power of the battery compartment group is superimposed on the charging of part of the batteries in the battery compartment group, the charging speed of part of the batteries is accelerated, and the user experience is improved. The battery charging efficiency is improved while reducing the waste of electric energy, and the cost is saved by avoiding the traditional battery swap station that configures each battery compartment with the maximum charging capacity of the battery to accelerate the charging speed of the battery.

[0216] Further, the battery compartment group is classified by the state of charge of the batteries in the battery compartment group to determine whether there is a battery that needs to be swapped in a battery compartment group, so that the battery in the battery swap station can operate, the battery charging efficiency is improved, and the charging time is reduced.

[0217] Further, by determining that the first compartment group type and the second compartment group type exist in the battery compartment group, it can be determined that there is a battery that needs to be swapped in a battery compartment group in the battery swap station, so that the battery can be swapped in a battery compartment group to improve the charging efficiency.

[0218] Further, by swapping less than half of the batteries in the battery compartment group corresponding to the first compartment group type with the batteries in the battery compartment group corresponding to the second compartment group type, the battery compartment group corresponding to the first compartment group type and the battery compartment group corresponding to the second compartment group type simultaneously contain full batteries and not full batteries. The charging efficiency of the battery can be improved without changing the overall power of the battery swap station, thereby avoiding the problem of low battery charging efficiency and long charging time caused by not full batteries in the same battery compartment group.

[0219] Further, when the second battery group type does not exist in the battery group, it is further judged whether the third battery group type exists in the battery group, and when the third battery group type exists, the battery with the state of charge less than the preset threshold in the battery group corresponding to the first battery group type is exchanged with the battery with the state of charge greater than or equal to the preset threshold in the battery group corresponding to the third battery group type, so that the charging efficiency of the battery can be improved.

[0220] Further, before judging whether the first battery group type exists in the battery group, it is preferred to judge whether the battery compartment corresponding to the battery group has a charging failure, so that the charging of the battery is not affected by the failure of the battery compartment, and the speed and safety of the battery in the charging process are ensured.

[0221] Further, when the battery compartment has a charging failure and there is a full battery in other battery groups, the full battery is exchanged with the battery in the battery compartment with the charging failure, so that the speed and safety of the battery in the charging process are ensured.

[0222] Further, according to the size of the first ratio and the second preset threshold and the size of the state of charge of the non-full battery under the same battery type and the first preset threshold, the battery compartment corresponding to the battery is classified to determine whether there is a battery type that needs to be exchanged, and when there is a need, the charging speed of the battery corresponding to the first battery type can be improved by exchanging the battery compartment.

[0223] Further, by judging that the first battery type and the second battery type exist in the battery compartment at the same time, it can be determined that there is a battery type that needs to be exchanged, so that the charging efficiency of the battery corresponding to the first battery type can be improved.

[0224] Further, by exchanging the battery with the state of charge less than the first preset threshold in the battery compartment corresponding to the first battery type with the battery with the state of charge less than the first preset threshold in the battery compartment corresponding to the second battery type, the charging efficiency of the battery corresponding to the first battery type can be improved.

[0225] Further, by charging the battery in the battery compartment according to the battery type and the number, the proportion of each battery type in the battery compartment and the proportion of each battery type in the battery swap station can be ensured to be consistent, so that the battery swap experience of users of vehicles with different types of batteries can be consistent.

[0230] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. For example, although the steps in the following examples are described in a certain order, those skilled in the art can understand that, in order to achieve the effect of the present embodiment, the different steps do not have to be executed in such an order, they can be executed simultaneously (in parallel) or in a reversed order, and these simple changes are within the protection scope of the present application.

[0231] Firstly, referring to Figure 2 , the battery swap station of the present application is introduced. Among them, Figure 2 A system diagram of the battery charging method of the battery swap station of the present application.

[0232] As Figure 2 shown, the battery swap station of the present application includes a master control system, in-station electrical equipment and n battery compartment groups, n is a positive integer greater than or equal to 1, each battery compartment group includes at least two battery compartments and a switch is arranged between the battery compartments, each battery compartment includes a charging branch, so that the switch is arranged between at least two charging branches of the battery compartment group, when the battery is in the battery compartment, the charging branch is engaged with the battery and charges the battery, and due to the arrangement of the switch, the multiple charging branches in the battery compartment group can be combined together, so that the power of the multiple battery compartments in the same battery compartment group is superimposed, flexible charging is performed on part of the batteries in the battery compartment group, and thus the charging speed of the battery is improved. The master control system is arranged in the battery swap station, each battery compartment is connected to the master control system, so that the master control system sends a power distribution instruction to the battery compartment to control the charging power of the battery compartment. Each charging branch includes a charging control board and an AC / DC module, the charging control board is connected to the master control system, the AC / DC module and the battery compartment, so that the charging control board realizes real-time information collection of the battery in the battery compartment and the AC / DC module and controls the branch to charge the battery; the charging control board of each branch interacts with the master control system, uploads the related information of the branch in real time, and accepts the control of the master control system.

[0233] It should be noted that the battery swap station further includes a power meter, which is connected to the control system and is used to measure the overall power of the battery swap station, and to allocate the power of each charging device based on the overall power, so as to realize real-time load power monitoring of the entire station, avoid tripping and device damage caused by power overrunning of the station from the power source, and reduce operation and maintenance costs.

[0234] Among them, the in-station power consumption equipment mainly refers to other power consumption equipment except the battery compartment, including but not limited to battery replacement process equipment (such as battery replacement trolley, battery transfer equipment, lifting mechanism, locking and unlocking mechanism, positioning mechanism, etc.), lighting equipment, communication equipment, etc.

[0235] Next, combined with Figure 1 and Figure 3 , the battery charging method of the battery swap station of the present application is introduced. Figure 1 The flowchart of the battery charging method of the battery swap station of the present application, Figure 3 The logic diagram of one possible implementation of the battery charging method of the battery swap station of the present application.

[0236] As Figure 1 and 3 shown, in order to solve the problem of how to improve the battery charging efficiency while reducing the waste of electric energy, the battery charging method of the battery swap station of the present application includes:

[0237] S101, obtaining the battery state information in the battery compartment group, the state information of the battery including the state of charge of the battery. For example, the battery state information includes but is not limited to the state of charge of the battery, wherein the state of charge refers to the ratio of the remaining capacity of the battery to the capacity of its fully charged state, and the state of charge of the battery can be determined by a device for detecting the state of charge, so as to obtain the state of charge in the battery compartment group.

[0238] S102, judging whether there is a battery that needs to be replaced in the battery compartment group based on the battery state information. For example, after obtaining the battery state information, the battery condition in each battery compartment group can be known by comparing the size of the state of charge, so as to judge whether there is a battery that needs to be replaced in the battery compartment group in the battery swap station.

[0239] S103, when there is a battery that needs to be replaced in the battery compartment group, replacing the battery in the battery compartment group based on the flexible charging strategy. For example, when it is determined that the battery needs to be replaced in the battery compartment group, the battery can be replaced in the battery compartment group based on the flexible charging strategy.

[0240] The present application judges whether there is a battery that needs to be replaced in the battery compartment group based on the battery state information, and when there is a battery that needs to be replaced in the battery compartment group, the battery is replaced in the battery compartment group based on the flexible charging strategy, so that the battery swap station can replace the battery in the battery compartment group, the charging power of the battery compartment group is superimposed for charging part of the battery, the charging speed of part of the battery is accelerated, the user experience is improved, the battery charging efficiency is improved while reducing the waste of electric energy, and the cost is saved by avoiding the traditional battery swap station which configures each battery compartment with the maximum charging capacity of the battery in order to accelerate the charging speed of the battery.

[0241] The preferred embodiments of the battery charging method of the battery swap station of the present application are described below.

[0242] In an embodiment, before the step of "judging whether there is a battery that needs to be replaced in the battery compartment group based on the state information of the battery", the method further comprises:

[0243] judging whether the battery compartment corresponding to the battery compartment group has a charging failure;

[0244] when there is no charging failure, judging whether there is a battery that needs to be replaced in the battery compartment group.

[0245] For example, taking the case where each battery compartment group in the battery swap station includes two battery compartments as an example. In order to judge whether the battery compartment has a charging failure, the following method can be used: when the battery in the No. 1 battery compartment of the No. 1 battery compartment group is not fully charged, the state of charge SOC1 of the battery in the No. 1 battery compartment at time t1 and the state of charge SOC2 at time t2 can be obtained, where t2 is greater than t1. By judging the magnitude of the state of charge of the battery at the two times, it can be determined whether the battery compartment has a charging failure. When SOC2 > SOC1, it indicates that the battery can be charged, and the battery compartment has no charging failure. When SOC1 = SOC2, it indicates that the battery cannot be charged, and the battery compartment has a charging failure. When the battery has no charging failure, it is further judged whether there is a battery that needs to be replaced in the battery compartment group.

[0246] Further, the battery charging method of the battery swap station further comprises:

[0247] when there is a charging failure, judging whether there is a fully charged battery in other battery compartment groups;

[0248] when there is a fully charged battery in other battery compartment groups, the fully charged battery and the battery in the battery compartment with a charging failure are replaced in the battery compartment group.

[0249] For example, taking the case where there are 10 battery compartment groups in the battery swap station, and each battery compartment group includes two battery compartments as an example. When the No. 1 battery compartment of the No. 1 battery compartment group is normal and the No. 2 battery compartment has a charging failure, the battery in the No. 3 battery compartment of the No. 2 battery compartment group is fully charged, the battery in the No. 4 battery compartment is still in a charging state, and the batteries in the two battery compartments of the remaining battery compartment groups are all in a charging state. At this time, the battery in the No. 2 battery compartment and the battery in the No. 3 battery compartment can be replaced, so that the battery in the battery compartment with a charging failure can enter the No. 3 battery compartment for charging, and the battery in the original No. 3 battery compartment does not need to be charged because it is fully charged, so it can enter the No. 2 battery compartment.

[0250] In an embodiment, before the step of "obtaining the state information of the battery in the battery compartment group", the method further comprises:

[0251] obtaining the number of all batteries in the battery swap station and the number of battery bays;

[0252] comparing the number of batteries with the number of battery bays;

[0253] when the number of batteries is less than or equal to the number of battery bays, all the batteries are put into the battery bays for charging;

[0254] when the number of batteries is greater than the number of battery bays, the types and the number of batteries are obtained, and based on the types and the number of batteries, the types and the number of batteries put into the battery bays are determined.

[0255] The method of determining the types and the number of batteries put into the battery bays based on the types and the number of batteries includes two methods.

[0256] Specifically, in an alternative embodiment, the step of "determining the types and the number of batteries put into the battery bays based on the types and the number of batteries" further includes:

[0257] calculating a second ratio between the number of batteries of different types;

[0258] based on the result of the second ratio, the types and the number of batteries put into the battery bays are calculated;

[0259] based on the calculation result, the batteries are put into the battery bays for charging.

[0260] For example, taking the number of batteries in the battery swap station as 24 and the number of battery bays as 24, the number of batteries in the battery swap station is equal to the number of battery bays, and at this time, the batteries in the battery swap station are directly put into the battery bays for charging. For another example, taking the size of the cruising range as the standard for classifying batteries, and taking the number of batteries in the battery swap station as 24, including 6 batteries with a cruising range of 300Km, 12 batteries with a cruising range of 200Km, and 6 batteries with a cruising range of 100Km, and taking the number of battery bays as 12, the number of batteries in the battery swap station is greater than the number of battery bays, and the second ratio between the number of batteries with a cruising range of 300Km, the number of batteries with a cruising range of 200Km, and the number of batteries with a cruising range of 100Km is 1:2:1. According to the ratio, the number of batteries with different cruising ranges put into the battery bays can be calculated, i.e., the number of batteries with a cruising range of 300Km, the number of batteries with a cruising range of 200Km, and the number of batteries with a cruising range of 100Km put into the battery bays is 3, 6 and 3 respectively.

[0261] In another alternative embodiment, the step of "determining the types and the number of batteries put into the battery bays based on the types and the number of batteries" further includes:

[0262] calculating a third ratio of the number of the battery of different battery types to the number of all batteries in the battery swap station;

[0263] based on the third ratio, calculating the number of each battery type in the battery compartment;

[0264] based on the calculation result, placing the battery in the battery compartment for charging.

[0265] For example, still taking the size of the cruising range as the standard for battery classification, and the number of batteries in the battery swap station is 24, including 6 batteries with a cruising range of 300Km, 12 batteries with a cruising range of 200Km, and 6 batteries with a cruising range of 100Km, and the number of battery compartments is 12. The number of batteries in the battery swap station is greater than the number of battery compartments, the third ratio of the battery with a cruising range of 300Km is 1 / 2, the third ratio of the battery with a cruising range of 200Km is 1 / 4, and the third ratio of the battery with a cruising range of 100Km is 1 / 4. At this time, based on the third ratio of the battery with three different cruising ranges, the number of each cruising range battery placed in the battery compartment can be calculated, that is, the number of batteries with a cruising range of 300Km, a cruising range of 200Km and a cruising range of 100Km placed in the battery compartment is 3, 6 and 3 respectively.

[0266] In an embodiment, before the step of "judging whether there is a battery that needs to be replaced in the battery compartment group", it further includes:

[0267] classifying the battery compartment group according to the state of charge of the battery;

[0268] based on the classification of the battery compartment group, judging whether there is a battery that needs to be replaced in the battery compartment group;

[0269] The type of the battery compartment group includes a first compartment group type and a second compartment group type, and all batteries in the battery compartment group corresponding to the first compartment group type are not fully charged, and all batteries in the battery compartment group corresponding to the second compartment group type are fully charged.

[0270] Specifically, the step of "judging whether there is a battery that needs to be replaced in the battery compartment group based on the classification of the battery compartment group" further includes:

[0271] judging whether there is a first compartment group type in the battery compartment group;

[0272] When there is a first compartment group type, it is judged whether there is a second compartment group type;

[0273] When there is a second compartment group type, it is determined that there is a battery that needs to be replaced in the battery compartment group.

[0274] For example, it is assumed that there are 10 battery compartment groups in the battery swap station, and each battery compartment group includes two battery compartments. When the batteries in the first battery compartment and the second battery compartment of the first battery compartment group are in the charging state, the batteries in the third battery compartment and the fourth battery compartment of the second battery compartment group are fully charged, and the batteries in one battery compartment of the remaining battery compartment groups are in the charging state, and the batteries in the other battery compartment are fully charged. Therefore, the first battery compartment group belongs to the first compartment group type, and the second battery compartment group belongs to the second compartment group type. Since the first compartment group type and the second compartment group type exist in the battery swap station at the same time, it can be determined that there are batteries that need to be swapped in the battery swap station.

[0275] Specifically, when there are batteries that need to be swapped, the step of "swapping the batteries in the battery compartment groups based on the flexible charging strategy" further includes:

[0276] When there are batteries that need to be swapped, swap less than half of the batteries in the battery compartment group corresponding to the first compartment group type with the batteries in the battery compartment group corresponding to the second compartment group type.

[0277] For example, it is assumed that there are 10 battery compartment groups in the battery swap station, and each battery compartment group includes two battery compartments. When the batteries in the first battery compartment and the second battery compartment of the first battery compartment group are in the charging state, the batteries in the third battery compartment and the fourth battery compartment of the second battery compartment group are fully charged, and the batteries in one battery compartment of the remaining battery compartment groups are in the charging state, and the batteries in the other battery compartment are fully charged. Therefore, the first battery compartment group belongs to the first compartment group type, and the second battery compartment group belongs to the second compartment group type. Since the first compartment group type and the second compartment group type exist in the battery swap station at the same time, it can be determined that there are batteries that need to be swapped in the battery swap station.

[0278] Of course, the batteries in the No. 1 battery compartment can also be exchanged with the batteries in the No. 4 battery compartment, or the batteries in the No. 2 battery compartment can be exchanged with the batteries in the No. 3 battery compartment, or the batteries in the No. 2 battery compartment can be exchanged with the batteries in the No. 4 battery compartment, which can also improve the charging speed of the two batteries in the original No. 1 battery compartment group.

[0279] In an embodiment, the type of the battery compartment group further includes a third compartment group type, when more than half of the batteries in the battery compartment group corresponding to the third compartment group type are full batteries and the state of charge of the batteries that are not full is greater than or equal to the first preset threshold value, the battery charging method of the battery swap station further includes:

[0280] When the second compartment group type does not exist, it is determined whether the third compartment group type exists;

[0281] When the third compartment group type exists, it is determined, based on the state of charge of the batteries in the battery compartment group corresponding to the first compartment group type, whether there is a battery in the battery compartment group corresponding to the first compartment group type whose state of charge is less than the first preset threshold value;

[0282] When there is a battery in the battery compartment group corresponding to the first compartment group type whose state of charge is less than the first preset threshold value, the battery is exchanged with a battery in the battery compartment group corresponding to the third compartment group type whose state of charge is greater than or equal to the first preset threshold value.

[0283] For example, there are 10 battery compartment groups in the battery swap station, each group includes two battery compartments, and the first preset threshold is 50%. The state of charge of the battery in the first battery compartment of the first battery compartment group is 70%, the state of charge of the battery in the second battery compartment is 30%, the battery in the fifth battery compartment of the third battery compartment group is fully charged, and the state of charge of the battery in the sixth battery compartment is 60%. The batteries in the remaining battery compartments are fully charged, and the state of charge of the battery in the other battery compartment is less than 50%. At this time, the first compartment type and the third compartment type exist in the battery swap station, and the state of charge of the battery in the second battery compartment of the first compartment type is less than the first preset threshold. At this time, the battery in the second battery compartment and the battery in the sixth battery compartment can be exchanged in the battery compartment group, so that the battery in the second battery compartment of the first battery compartment group enters the sixth battery compartment of the third battery compartment group for charging, and the battery in the sixth battery compartment of the original third battery compartment enters the second battery compartment of the first battery compartment group. Thus, the power of the two battery compartments in the third battery compartment group is added to charge the battery in the sixth battery compartment, and the state of charge of the two batteries in the first battery compartment group is greater than the preset threshold. At this time, the two batteries are charged according to the charging power allocated by the battery swap station to each charging compartment, thereby improving the charging speed of the battery in the original second battery compartment. Moreover, the state of charge of the batteries in the original first battery compartment and the sixth battery compartment is greater than the preset threshold. At this time, the demand power of the two batteries is low, and the charging power allocated by the battery swap station to each charging compartment can meet the charging demand of the battery.

[0284] For example, when the state of charge of the battery in the first battery compartment of the first battery compartment group is 40%, the state of charge of the battery in the second battery compartment is 30%, and the other conditions are the same as above. That is, there are two batteries in the first battery compartment group whose state of charge is less than the first preset threshold. At this time, the battery in the first battery compartment and the battery in the sixth battery compartment can be exchanged in the battery compartment group, or the battery in the second battery compartment and the battery in the sixth battery compartment can be exchanged in the battery compartment group, thereby improving the charging efficiency of the battery.

[0285] In an embodiment, the battery charging method of the battery swap station further comprises

[0286] When there is no third compartment type, the types of all batteries in the battery compartment are obtained;

[0287] The first ratio of the number of fully charged batteries to the batteries of the same battery type is calculated;

[0288] The first ratio and the second preset threshold are compared, and the state of charge of the non-fully charged battery of the same battery type and the first preset threshold are compared;

[0289] Based on the comparison result, the battery compartment corresponding to the battery is classified;

[0290] determine whether there is a battery type that needs to be replaced based on the classification result of the battery compartment;

[0291] when there is a battery type that needs to be replaced, replace the battery compartment of the battery type that needs to be replaced based on the flexible charging strategy;

[0292] The type of the battery compartment includes a first compartment type and a second compartment type. The first ratio of the battery type corresponding to the first compartment type is less than the second preset threshold, and the state of charge of the battery with an uncharged battery in the battery type is less than the first preset threshold. The first ratio of the battery type corresponding to the second compartment type is greater than or equal to the second preset threshold, and the state of charge of the battery with an uncharged battery in the battery type is less than the first preset threshold.

[0293] Specifically, the step of "determining whether there is a battery type that needs to be replaced based on the classification result of the battery compartment" further includes:

[0294] determine whether there is a first compartment type;

[0295] when there is a first compartment type, determine whether there is a second compartment type;

[0296] when there is a second compartment type, it is determined that there is a battery type that needs to be replaced.

[0297] For example, there are 6 groups of battery compartments in the battery swap station, the first preset threshold is 50%, the second preset threshold is 0.5, and each group of battery compartments includes two battery compartments, 6 batteries with a mileage of 300Km and 6 batteries with a mileage of 200Km in each battery compartment. The batteries in the 6 battery compartments of the 1st battery compartment group, the 2nd battery compartment group and the 3rd battery compartment group are all batteries with a mileage of 300Km, and the batteries in the 6 battery compartments of the 4th battery compartment group, the 5th battery compartment group and the 6th battery compartment group are all batteries with a mileage of 200Km. Among them, the state of charge of the battery in the 1st battery compartment of the 1st battery compartment group is 80%, and the state of charge of the battery in the 2nd battery compartment is 40%, the state of charge of the battery in the 3rd battery compartment of the 2nd battery compartment group is 70%, and the state of charge of the battery in the 4th battery compartment is 50%, the state of charge of the battery in the 5th battery compartment of the 3rd battery compartment group is 70%, and the state of charge of the battery in the 6th battery compartment is 40%. The battery in the 7th battery compartment of the 4th battery compartment group is full, and the state of charge of the battery in the 8th battery compartment is 40%, the battery in the 9th battery compartment of the 5th battery compartment group is full, and the state of charge of the battery in the 10th battery compartment is 50%, the battery in the 11th battery compartment of the 6th battery compartment group is full, and the state of charge of the battery in the 12th battery compartment is 40%. At this time, the battery compartment corresponding to the battery with a mileage of 300Km belongs to the first compartment type, and the battery compartment corresponding to the battery with a mileage of 200Km belongs to the second compartment type, because there are first and second compartment types in the battery swap station at the same time, it is determined that there is a battery type that needs to be replaced.

[0298] Further, the step of "when there is a battery type that needs to be replaced, then based on the flexible charging strategy, the battery type that needs to be replaced is replaced" further includes;

[0299] When there is a battery type that needs to be replaced, the battery with a state of charge less than the first preset threshold in the first compartment type corresponding battery compartment is replaced with the battery with a state of charge less than the first preset threshold in the second compartment type corresponding battery compartment.

[0300] For example, there are 6 groups of battery compartment groups in the battery swap station, the first preset threshold is 50%, the second preset threshold is 0.5, and each group of battery compartment groups includes two battery compartments, and the battery compartments include 6 batteries with a mileage of 300Km and 6 batteries with a mileage of 200Km. The 6 battery compartments in the 1st battery compartment group, the 2nd battery compartment group, and the 3rd battery compartment group all contain batteries with a mileage of 300Km, and the 6 battery compartments in the 4th battery compartment group, the 5th battery compartment group, and the 6th battery compartment group all contain batteries with a mileage of 200Km. Among them, the state of charge of the battery in the 1st battery compartment of the 1st battery compartment group is 80%, and the state of charge of the battery in the 2nd battery compartment is 40%. The state of charge of the battery in the 3rd battery compartment of the 2nd battery compartment group is 70%, and the state of charge of the battery in the 4th battery compartment is 50%. The state of charge of the battery in the 5th battery compartment of the 3rd battery compartment group is 70%, and the state of charge of the battery in the 6th battery compartment is 40%. The battery in the 7th battery compartment of the 4th battery compartment group is fully charged, and the state of charge of the battery in the 8th battery compartment is 40%. The battery in the 9th battery compartment of the 5th battery compartment group is fully charged, and the state of charge of the battery in the 10th battery compartment is 50%. The battery in the 11th battery compartment of the 6th battery compartment group is fully charged, and the state of charge of the battery in the 12th battery compartment is 40%. At this time, the battery compartment corresponding to the battery with a mileage of 300Km belongs to the first compartment type, and the battery compartment corresponding to the battery with a mileage of 200Km belongs to the second compartment type. At this time, the battery in the 2nd battery compartment can be exchanged with the battery in the 8th battery compartment, the battery in the 4th battery compartment can be exchanged with the battery in the 10th battery compartment, and the battery in the 6th battery compartment can be exchanged with the battery in the 12th battery compartment, thereby improving the charging speed of the battery with a mileage of 300Km.

[0301] For example, there are 6 groups of battery compartments in the battery swap station, and each group of battery compartments includes two battery compartments. There are 3 batteries with a mileage of 300Km, 6 batteries with a mileage of 200Km, and 3 batteries with a mileage of 100Km in the battery compartments. The first preset threshold is 40%, and the second preset threshold is 50%. In the 1st battery compartment group, the 1st battery compartment and the 2nd battery compartment and the 3rd battery compartment in the 2nd battery compartment group all have batteries with a mileage of 300Km. The 4th battery compartment in the 2nd battery compartment group, the 5th battery compartment and the 6th battery compartment in the 3rd battery compartment group, the 7th battery compartment and the 8th battery compartment in the 4th battery compartment group, and the 9th battery compartment in the 5th battery compartment group all have batteries with a mileage of 200Km. The 10th battery compartment in the 5th battery compartment group and the 11th battery compartment and the 12th battery compartment in the 6th battery compartment group all have batteries with a mileage of 100Km. The batteries in the 1st battery compartment, the 3rd battery compartment, the 5th battery compartment, the 7th battery compartment, the 10th battery compartment, the 11th battery compartment are all full batteries. The state of charge of the battery in the 2nd battery compartment is 40%, the state of charge of the battery in the 4th battery compartment is 30%, the state of charge of the battery in the 6th battery compartment is 45%, the state of charge of the battery in the 8th battery compartment is 30%, the state of charge of the battery in the 9th battery compartment is 30%, and the state of charge of the battery in the 12th battery compartment is 40%. At this time, the battery compartment corresponding to the battery with a mileage of 300Km belongs to the first compartment type, and the battery compartment corresponding to the battery with a mileage of 200Km belongs to the second compartment type. At this time, the battery in the 2nd battery compartment and the battery in the 6th battery compartment can be exchanged, and the battery in the 4th battery compartment and the battery in the 8th battery compartment can be exchanged, so as to improve the charging speed of the battery with a mileage of 300Km.
