Description

Technical Field

[0001] The present invention relates to the technical field of power swap cabinets, and in particular to a charging scheduling method, device and storage medium for a power swap cabinet. Background Art

[0002] Electric vehicles, such as electric bicycles and electric motorcycles, have become an indispensable means of transportation in daily life due to their portability, low cost and many other advantages. However, electric vehicles also have obvious problems, among which the main ones are charging safety and long charging time.

[0003] As for the problem of long charging time, this is because the charging power of the on-board charger equipped with the electric vehicle is relatively small, so the charging speed is relatively slow. As for the charging safety issue, this is due to the lack of safety protection measures for both the on-board charger and the electric vehicle. Due to the existence of these two problems, there have been more and more fire incidents caused by indoor charging of electric vehicles in recent years. Therefore, it is recommended that electric vehicles be charged at outdoor charging stations to reduce the losses caused by electric vehicle fires. However, if charging is done at an outdoor charging station, the outdoor charging station will limit the charging power of the on-board charger, and the charging speed will be even slower. Therefore, this is quite unfriendly to some users who need to use electric vehicles frequently and for a very long time (such as deliverymen and couriers).

[0004] For this reason, the battery swap cabinet came into being. The battery swap cabinet is a device that can store electric vehicle batteries and has intelligent charging management. Generally speaking, the battery swap process is that the user returns the low-power electric vehicle battery to the battery swap cabinet and rents a fully charged battery from the battery swap cabinet. In this way, the user can continue to use the electric vehicle, thus solving the technical problems mentioned above.

[0005] In some existing battery swap cabinets, each charging compartment is equipped with a charger. Although this type of battery swap cabinet can ensure the battery swap needs of users, the implementation cost is too high. Therefore, it is urgent to reduce the implementation cost of the battery swap cabinet and at the same time meet the battery swap needs of users as much as possible, for example, to meet the battery swap needs of users as much as possible during the peak period of battery swap. Summary of the invention

[0006] The present invention provides a charging scheduling method, device and storage medium for a battery swap cabinet, which are used to reduce the implementation cost of the battery swap cabinet and meet the power demand of users as much as possible.

[0019] If the power level is less than the fast charge upper limit value, determining a first target mutually exclusive bin group from the multiple mutually exclusive bin groups;

[0020] After determining whether the current power of the battery to be returned is greater than the fast charge upper limit power value according to the power information of the battery to be returned, the method further includes:

[0021] If it is greater than or equal to the fast-charge upper limit power value, a third target mutually exclusive warehouse group is determined from the multiple mutually exclusive warehouse groups; one charging warehouse in the third target mutually exclusive warehouse group is charging the second battery and the current power of the second battery is less than the fast-charge upper limit power value, and the other charging warehouse is empty;

[0022] The empty bin in the third target mutually exclusive bin group is used as a return bin, and after the user returns the battery and the second battery is fully charged, the returned battery is charged.

[0023] Optionally, after the user returns the battery, the method further includes:

[0024] A fourth target mutually exclusive bin group is determined from the multiple mutually exclusive bin groups; two charging bins in the fourth target mutually exclusive bin group are both equipped with third batteries whose power is greater than or equal to the fast charging upper limit power value;

[0028] After executing the environmental improvement strategy, monitor again whether the environmental parameters of the returned battery are within the warning range. If so, reduce the current charging level of the returned battery, wherein the charging level of the returned battery is positively correlated with the charging speed of the returned battery.

[0029] Optionally, after the environmental improvement strategy is executed, the environmental parameter of the returned battery is monitored again to see whether it is within the warning range, and if so, the current charging level of the returned battery is reduced, further comprising:

In this way, the battery can be charged immediately after the return or charged immediately after waiting for a short time. In this way, the battery can be charged to meet the replacement requirements as soon as possible, so as to meet the user's battery replacement needs as much as possible.

[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] In order to make the description of the disclosed content more detailed and complete, the following is an illustrative description of the implementation mode and specific examples of the present invention; however, this is not the only form of implementing or applying the specific embodiments of the present invention. The implementation mode covers the features of multiple specific embodiments and the method steps and their sequence for constructing and operating these specific embodiments. However, other specific embodiments can also be used to achieve the same or equal functions and step sequences. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0054] In the description of the embodiments of the present invention, unless otherwise specified, "and / or" in the text is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present invention, "multiple" refers to two or more than two, and other quantifiers are similar. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features therein may be combined with each other without conflict.

[0055] The charging scheduling method of a battery swap cabinet provided in an embodiment of the present invention can be applied to the battery swap cabinet, that is, the battery swap cabinet can be the execution subject of the method provided in an embodiment of the present invention. Figure 1 As shown, the battery swap cabinet has multiple charging bays 10, wherein the two charging bays 10 in each row constitute a mutually exclusive bay group, and the two charging bays 10 in each mutually exclusive bay group share a charger. It can be understood that since every two charging bays 10 share a charger, compared with the prior art in which each charging bay uses a charger, the cost of the charger can be effectively saved, thereby effectively saving the implementation cost of the battery swap cabinet.

[0056] like Figure 2 As shown, the charging scheduling method may include steps S110 to S140.

[0057] Step S110: In response to the battery replacement request, determine a first target mutually exclusive warehouse group from multiple mutually exclusive warehouse groups.

[0058] A battery replacement request refers to a request from a user to replace a battery, and the battery replacement cabinet may obtain the battery replacement request in any feasible manner. For example, when a user needs to replace a battery, the user may send a battery replacement request to the server through a mobile terminal, and the server may then send the request to the battery replacement cabinet.

[0059] Among multiple mutually exclusive bin groups, there are generally the following types of mutually exclusive bin groups, where both charging bins in the mutually exclusive bin group are not charging batteries and at least one charging bin is empty, and this type of mutually exclusive bin group is the first target mutually exclusive bin group. For example, in a mutually exclusive bin group, both charging bins do not contain batteries, and this mutually exclusive bin group is the first target mutually exclusive bin group. For another example, in a mutually exclusive bin group, one charging bin does not contain a battery, and the other charging bin contains a fully charged battery (it can be understood that this charging bin no longer needs to charge the battery, that is, it is not charging the battery), and this mutually exclusive bin group is also the first target mutually exclusive bin group.

[0060] It should be noted that judging whether a battery is placed in the charging compartment is already a prior art, for example, it can be achieved through an in-place detection element. It should also be noted that judging whether the charging compartment is charging the battery is also a prior art, for example, if the charger is connected to the charging compartment and the charger has an output current, it means that the charging compartment is charging the battery at this time; for another example, if the charger is connected to the charging compartment but the charger has no output current, it means that the charging compartment is not charging the battery at this time; for another example, if the charger is not connected to the charging compartment at this time, it means that the charging compartment is not charging the battery at this time.

[0061] Step S120: Use the empty bin in the first target mutually exclusive bin group as the return bin, and charge the returned battery after the user returns the battery.

[0062] After responding to the battery replacement request, the battery that the user needs to return should be recovered first. For the battery that the user needs to return (usually in a depleted state), in order to meet the user's battery replacement needs as much as possible, it is best to charge it immediately after the battery is successfully returned. Therefore, after the power exchange cabinet determines a first target mutually exclusive bin group, it can use the empty bin in this mutually exclusive bin group as a return bin for the user to return the battery, for example, by popping open the bin door of the empty bin. After the user successfully returns the battery, the returned battery can be charged immediately. It can be understood that when responding to the battery replacement request, the charger corresponding to the first target mutually exclusive bin group is not working and is idle. Therefore, the embodiment of the present invention selects the empty bin in the first target mutually exclusive bin group for the user to return the battery, so that it can be charged immediately after the return, so that the battery can be charged to meet the replacement requirements as soon as possible. For example, after the user puts the depleted battery into the empty bin and closes the cabinet door of the empty bin, the charger can be controlled to connect to the empty bin to charge the battery. Assuming that a battery meets the replacement requirements and must have a power level of more than 90% (of course it can also be other reasonable power values, such as 80%, etc.), then when the battery is charged to 90% power, the battery can be taken away by the user for battery replacement.

[0063] Step S130: If the first target mutually exclusive bin group does not exist, determine a plurality of second target mutually exclusive bin groups from the plurality of mutually exclusive bin groups.

[0064] Of course, the first target mutually exclusive compartment group may not exist in the battery swap cabinet at this time, but in order to meet the power demand as much as possible, after the battery is successfully returned, it is best to charge it immediately or keep the charging waiting time as short as possible.

[0065] To this end, on the one hand, the inventor found that the charging process of the battery is roughly divided into two stages, the first stage is fast charging, and the second stage is slow charging. For example, when the power is lower than a certain value (such as 90%), fast charging is adopted, and when the power is higher than a certain value (such as 90%), slow charging is adopted. It should be noted that the embodiment of the present invention names this value as the fast charging upper limit power value, which can be reasonably set according to the actual situation such as battery type and charging equipment during specific implementation. It can be seen that when a battery is being charged and its power has exceeded the fast charging upper limit power value, the time required for the battery to be fully charged is relatively short, or, if the charging is terminated at this time and the battery is taken out for use, it will basically not affect the user experience. On the other hand, there are generally the following types of mutually exclusive warehouse groups in multiple mutually exclusive warehouse groups, in which one charging warehouse in the mutually exclusive warehouse group is charging a first battery and the current power of the first battery is greater than or equal to the fast charging upper limit power value, and the other charging warehouse is an empty warehouse, then this type of mutually exclusive warehouse group is the second target mutually exclusive warehouse group. For example, the upper limit power value of fast charging may be 90%. Then, assuming there is a mutually exclusive bin group, one charging bin is charging a battery with a power level of 91%, and the other charging bin has no battery placed therein, this mutually exclusive bin group is the second target mutually exclusive bin group.

[0066] Based on this, if the first target mutually exclusive bin group does not exist at this time, in order to meet the power demand as much as possible, one or more second target mutually exclusive bin groups can be determined. For example, one second target mutually exclusive bin group can be determined, or all second target mutually exclusive bin groups can be determined and then selected.

[0067] Step S140: Use an empty bin in one of the second target mutually exclusive bin groups as a return bin, and charge the returned battery after the user returns the battery.

[0068] After determining a number of second target mutually exclusive bin groups, one of the second target mutually exclusive bin groups can be selected, and the empty bin in the selected second target mutually exclusive bin group can be used as the return bin. After the user returns the battery, the returned battery can be charged after the first battery in the selected second target mutually exclusive bin group is fully charged, or the returned battery can be charged immediately. It is also understandable that in this way, the battery can be charged immediately after the return or immediately after waiting for a short time, so that the battery can be charged to meet the replacement requirements as soon as possible.

[0069] For example, it is assumed that the power exchange cabinet includes five mutually exclusive compartment groups, namely mutually exclusive compartment group A, mutually exclusive compartment group B, mutually exclusive compartment group C, mutually exclusive compartment group D and mutually exclusive compartment group E. Among them, charging compartment A1 and charging compartment A2 in mutually exclusive compartment group A are both placed with fully charged batteries; charging compartment B1 and charging compartment B2 in mutually exclusive compartment group B are both not placed with batteries; charging compartment C1 in mutually exclusive compartment group C is placed with fully charged batteries, and charging compartment C2 is not placed with batteries; charging compartment D1 in mutually exclusive compartment group D is placed with batteries and is charging the batteries, the current power is 91%, and charging compartment D2 is not placed with batteries; charging compartment E1 in mutually exclusive compartment group E is placed with batteries and is charging the batteries, the current power is 69%, and charging compartment E2 is not placed with batteries.

[0070] Based on this, assuming that a deliveryman triggers a battery replacement request at this time, the battery swap cabinet will respond to the battery replacement request and determine a first target mutually exclusive bin group, for example, determine mutually exclusive bin group B, and use charging bin B1 as the return bin. After the deliveryman returns the battery, the charger corresponding to mutually exclusive bin group B is connected to charging bin B1 to charge the returned battery. Of course, the battery swap cabinet can select a battery that meets the replacement requirements and rent it to the deliveryman, such as a fully charged battery in charging bin A1.

[0071] Assume again that a few minutes have passed, and now there is no battery in charging compartment A1; there is a battery in charging compartment B1 and it is being charged, and the current charge is very low; charging compartment D1 is still charging the battery, and the current charge is 94%; charging compartment E1 is still charging the battery, and the current charge is 78%, and the rest remains unchanged. Assume that another deliveryman triggers a battery swap request, then after the battery swap cabinet responds to the battery swap request, it determines a first target mutually exclusive compartment group, for example, it determines mutually exclusive compartment group A, and uses charging compartment A1 as the return compartment. After the deliveryman returns the battery, the charger corresponding to mutually exclusive compartment group A is connected to charging compartment A1 to charge the returned battery. Similarly, the battery swap cabinet can select a battery that meets the replacement requirements and rent it to the deliveryman, such as a fully charged battery in charging compartment A2.

[0072] Assume that after a few minutes, a battery is placed in charging compartment A1 and is being charged, and the current power is very low; there is no battery in charging compartment A2; a battery is placed in charging compartment B1 and is being charged, although the battery power has increased but is still very low; charging compartment D1 is still charging the battery, and the current power is 98%; charging compartment E1 is still charging the battery, and the current power is 86%, and the rest remains unchanged. Assuming that two deliverymen trigger a battery swap request at almost the same time, the battery swap cabinet can respond to these two battery swap requests one after another. First, the battery swap cabinet responds to the battery swap request that is obtained first, and determines the first target mutually exclusive compartment group. At this time, there is only mutually exclusive compartment group C, then charging compartment C2 is used as the return compartment. After the deliveryman returns the battery, the charger corresponding to the mutually exclusive compartment group C is connected to charging compartment C2 to charge the returned battery. Similarly, the battery swap cabinet can select a battery that meets the replacement requirements and rent it to the deliveryman, such as a fully charged battery in charging compartment C1. It is understandable that the situation of the charging warehouse has changed at this time. Charging warehouse C1 has become empty, and charging warehouse C2 has become a place with batteries and is charging the batteries, and the current power is very low. Then, the power exchange cabinet responds to the battery exchange request obtained later, but the first target mutually exclusive warehouse group does not exist at this time. Assuming that the upper limit power value of fast charging is 90%, the second target mutually exclusive warehouse group is determined. At this time, there is only mutually exclusive warehouse group D, and charging warehouse D2 is used as the return warehouse. After the deliveryman returns the battery, there can be two implementation methods as described above. This example selects the implementation method of charging immediately. The charger corresponding to the mutually exclusive warehouse group D is disconnected from the charging warehouse D1, and connected to the charging warehouse D2 to charge the returned battery. Similarly, the power exchange cabinet can select a battery that meets the replacement requirements to rent to the deliveryman, such as a battery with a power in the charging warehouse D1 greater than the upper limit power value of fast charging. It is understandable that the power of this battery is 98% at this time, which has almost no impact on the user experience.

[0073] From the above example, it can be seen that the returned battery can be charged immediately after return, so that the battery can be charged to meet the replacement requirements as soon as possible, and the user's battery replacement needs can be met as much as possible.

[0074] In summary, in the battery swap cabinet of the embodiment of the present invention, every two charging compartments share one charger, which can greatly reduce the implementation cost of the battery swap cabinet. At the same time, when the user returns the battery, the empty compartment in the first target mutually exclusive compartment group is preferentially selected as the return compartment. If the first target mutually exclusive compartment group does not exist, the empty compartment in the second target mutually exclusive compartment group is selected as the return compartment. In this way, the battery can be charged immediately after the return or charged immediately after waiting for a short time. In this way, the battery can be charged to meet the replacement requirements as soon as possible, so as to meet the user's battery replacement needs as much as possible.

[0075] In some embodiments, "selecting an empty bin in one of the second target mutually exclusive bin groups as a return bin" in step S140 may include: selecting an empty bin in the second target mutually exclusive bin group where the first battery with the largest current power is located as the return bin.

[0076] As mentioned above, if there is no first target mutually exclusive bin group, several second target mutually exclusive bin groups can be determined. When there are multiple second target mutually exclusive bin groups, the second target mutually exclusive bin group with the largest current power of the first battery can be selected. In this way, after the user returns the battery, on the one hand, if the returned battery is charged after the first battery in the second target mutually exclusive bin group is fully charged, the present embodiment can minimize the charging waiting time; on the other hand, if the returned battery is charged immediately, it can be understood that the first battery with the largest current power will stop charging, but its power meets the replacement requirements and is closest to full charge, then the battery will be rented to the user, which can ensure the use experience to the greatest extent. Therefore, the embodiment of the present application is conducive to meeting the demand for battery replacement as much as possible.

[0077] Exemplarily, it is assumed that the power exchange cabinet includes mutually exclusive warehouse group F, mutually exclusive warehouse group G and mutually exclusive warehouse group H. Among them, the charging warehouse F1 in mutually exclusive warehouse group F has a battery placed and is charging the battery, and the current power is 91%, and the charging warehouse F2 has no battery placed; the charging warehouse G1 in mutually exclusive warehouse group G has a battery placed and is charging the battery, and the current power is 94%, and the charging warehouse G2 has no battery placed; the charging warehouse H1 in mutually exclusive warehouse group H has a battery placed and is charging the battery, and the current power is 96%, and the charging warehouse H2 has no battery placed. Based on this, when the power exchange cabinet responds to the power exchange request, it is assumed that there is no first target mutually exclusive warehouse group, and the determined several second target mutually exclusive warehouse groups are mutually exclusive warehouse group F, mutually exclusive warehouse group G and mutually exclusive warehouse group H. It is obvious that the second target mutually exclusive warehouse group where the first battery with the largest current power is located is the mutually exclusive warehouse group H, so the charging warehouse H2 can be selected as the return warehouse.

[0078] In some implementations of this embodiment, when an empty bin in the second target mutually exclusive bin group where the first battery with the largest current power is located is selected as the return bin, "charging the returned battery" in step S140 may include: stopping charging of the first battery with the largest current power, and charging the returned battery.

[0079] Please refer to the previous discussion for details. On the one hand, if the first battery with the largest current power is rented to the user, the user experience can be ensured to the greatest extent. On the other hand, if the returned battery is charged immediately, it can be charged to meet the replacement requirements as soon as possible.

[0080] In some embodiments, the battery replacement request may carry the power information of the battery to be returned. Exemplarily, the mobile terminal may allow the user to select the power information of the battery to be returned. For example, if the power value belongs to [0, 100], multiple intervals divided from [0, 100] may be provided, for example, divided into three intervals [0, 50], (50, 80], (80, 100]. Assuming that the user selects [0, 50], it can be determined that the power of the battery to be returned is less than or equal to 50%, so the battery replacement request may carry this power information. Exemplarily, the mobile terminal may allow the user to fill in the power of the battery to be returned. For example, the electric vehicle that the user rides may have the function of informing the user of the battery power. Assuming that the power is 21% when the user takes the battery out of the electric vehicle, the user can fill it in, so the battery replacement request may carry this power information.

[0081] Based on this, Figure 3 As shown, step S110 may include steps S111 to S112.

[0082] Step S111: In response to the battery replacement request, determine whether the current power of the battery to be returned is less than the fast charging upper limit power value based on the power information of the battery to be returned.

[0083] Step S112: If the power level is less than the upper limit of fast charging, a first target mutually exclusive bin group is determined from multiple mutually exclusive bin groups.

[0084] Normally, the batteries that users need to return are basically in a low-power state. However, in order to improve reliability, the power level of the battery to be returned can be confirmed when responding to the battery replacement request. If it is less than the fast charging upper limit, execute step S112 and subsequent steps.

[0085] In some implementations of this embodiment, Figure 4 As shown, after step S111, steps S113 to S114 may also be included.

[0086] Step S113: If the power level is greater than or equal to the upper limit of fast charging, a third target mutually exclusive bin group is determined from the multiple mutually exclusive bin groups.

[0087] Among them, one charging compartment in the third target mutually exclusive compartment group is charging a second battery and the current power of the second battery is less than the fast charging upper limit power value, and the other charging compartment is empty.

[0088] Step S114: Use the empty bin in the third target mutually exclusive bin group as the return bin, and after the user returns the battery and the second battery is fully charged, charge the returned battery.

[0089] Although the battery returned by the user is usually depleted, it is also possible that the user returns a fully charged or nearly fully charged battery. In this case, there is no need to charge such a battery immediately or to shorten the charging waiting time as much as possible. In order to meet the user's battery replacement needs as much as possible, the embodiment of the present application regards such a battery as a battery that meets the replacement requirements. Based on this, if it is determined that the power of the battery to be returned is greater than or equal to the fast charging upper limit power value, a third target mutually exclusive bin group is determined, and the empty bin therein is used as the return bin. At the same time, after the second battery therein is fully charged, if the returned battery still exists, it is charged again. In this way, the fully charged or nearly fully charged returned battery will not affect the charging of other batteries.

[0090] In some embodiments, Figure 5 As shown, after step S140, the charging scheduling method may further include step S150.

[0091] Step S150: determine a fourth target mutually exclusive bin group from the multiple mutually exclusive bin groups, and rent the third battery with a larger battery power in the fourth target mutually exclusive bin group to the user.

[0092] After the user successfully returns the battery, the power exchange cabinet needs to rent a new battery to the user. At this time, the power exchange cabinet can arbitrarily select a battery that meets the replacement requirements and rent it to the user. However, if the re-rental operation can increase the number of the first target mutually exclusive bin group or the second target mutually exclusive bin group, then this will help to meet the user's battery replacement needs as much as possible. For this reason, when selecting a re-rented battery, this embodiment selects a mutually exclusive bin group of the fourth target mutually exclusive bin group, in which both charging bins of the fourth target mutually exclusive bin group are placed with a third battery with a power greater than or equal to the fast charge upper limit power value. In this way, the third battery with a larger battery power in the fourth target mutually exclusive bin group can be selected to rent to the user.

[0093] Exemplarily, assuming that there is a mutually exclusive warehouse group, in which two charging warehouses are placed with fully charged batteries, you can choose any one of the batteries to rent to the user. It is understandable that at this time, one charging warehouse in this mutually exclusive warehouse group is placed with a fully charged battery, and the other is an empty warehouse, which is the first target mutually exclusive warehouse group. Exemplarily, assuming that there is a mutually exclusive warehouse group, in which one charging warehouse is placed with a fully charged battery, and the other charging warehouse is placed with a battery that is being charged and the current battery power is 95% (assuming that the upper limit of the fast charge capacity is 90%), then you can choose to rent a fully charged battery to the user. It is understandable that at this time, one charging warehouse in this mutually exclusive warehouse group is placed with a battery that is being charged and the current power is greater than the upper limit of the fast charge capacity, and the other is an empty warehouse, which is the second target mutually exclusive warehouse group.

[0094] In some embodiments, after step S140 , the charging scheduling method further includes steps S161 - S164 .

[0095] Step S161, charging the returned battery;

[0096] Step S162: When the power of the returned battery reaches a first threshold value, quickly charge the returned battery;

[0097] Step S163, when the power of the returned battery is charged to a second threshold interval, performing a second fast charge on the returned battery;

[0098] Step S164: When the power of the returned battery is charged to a third threshold range, the returned battery is slowly charged.

[0099] It should be noted that the end thresholds of the first threshold interval, the second threshold interval, and the third threshold interval can be set according to the specific needs of the application, and are not limited in detail here. For example, the maximum value of the first threshold interval can be less than or equal to the minimum value of the second threshold interval, and the maximum value of the second threshold interval can be less than or equal to the minimum value of the third threshold interval. When setting the first threshold interval and the second threshold interval, it can be ensured that the power of the returned battery is in the first threshold interval, and the returned battery after charging taken by the user can normally power the power consumption equipment, and it is ensured that the returned battery after charging is in the second threshold interval, and the returned battery taken by the user can power the power consumption equipment for more than 12 hours. Obviously, through the division of the above-mentioned threshold intervals, each battery in the power exchange cabinet can be charged to a state where it can normally power the power consumption equipment in a relatively short time, so that the high demand for power exchange can be met during the peak period of power exchange in the power exchange cabinet, and because the charging speed of the returned battery slows down after charging to the second threshold interval, the energy consumption of the charger can be reduced, thereby effectively saving costs.

[0100] It should be noted that the charging speeds of fast charging, sub-fast charging and slow charging can be set according to the specific needs of the application. Detailed limitations are not given here, but it is necessary to meet the requirement that the charging speed of fast charging is greater than the charging speed of sub-fast charging, and the charging speed of sub-fast charging is greater than the charging speed of slow charging.

[0101] In some embodiments, Figure 6 As shown, after step S140, the charging scheduling method further includes step S171 and step S172.

[0102] Step S171, monitoring environmental parameters during the charging process of the returned battery, if the environmental parameters are within the warning range, changing the environmental parameters through an environmental improvement strategy, if the environmental parameters exceed the warning range, stopping charging of the returned battery;

[0103] Step S172: After the environmental improvement strategy is executed, the environmental parameters of the returned battery are monitored again to see if they are within the warning range. If so, the current charging level of the returned battery is reduced.

[0104] The environmental parameters include the battery cell temperature and / or the humidity of the charging compartment. The charging level of the returned battery is positively correlated with the charging speed of the returned battery.

[0105] It should be noted that environmental parameters are external environmental factors that will affect the charging process of the returned battery. For example, environmental parameters can be air pressure, because at high altitudes, the air pressure is lower, which will affect the chemical reaction rate inside the battery and thus affect the charging performance. Environmental parameters can also be air quality parameters, because pollutants such as dust and particulate matter in the air may enter the battery or charging port, affecting the electrical connection and reducing the charging efficiency.

[0106] It should be noted that the warning range of environmental parameters can be set according to the specific situation of the application. Different warning ranges can usually be set for different environmental parameters, which are not specified in detail here. It should also be noted that if the environmental parameters are within the warning range, it means that the current change value of the environmental parameters is still within the controllable range. At this time, the environmental parameters can be improved to change the environmental parameters for the better. If the environmental parameters exceed the warning range, it means that the current environmental parameters may make the battery unable to charge normally. Therefore, in order to ensure the safety of the user's battery, the user's battery can be stopped from charging.

[0107] It should be noted that the environmental improvement strategy for changing environmental parameters can be set according to specific needs during application. For example, if the environmental parameter of air quality needs to be improved, air purification measures can be used to improve the air quality.

[0108] Specifically, the environmental parameters may include the battery cell temperature and / or the humidity of the charging compartment.

[0109] It is understandable that compared with other environmental parameters, the battery cell temperature and the humidity of the charging compartment are more easily affected and are within the warning range.

[0110] It should be noted that when the battery cell temperature is within the warning range, the environmental improvement strategy for changing the battery cell temperature may be to cool the battery cell by a fan or air conditioner. When the humidity of the charging compartment is within the warning range, the environmental improvement strategy for changing the humidity of the charging compartment may be to dry the charging compartment by a fan to reduce the humidity.

[0111] It can be understood that lowering the charging level of the returned battery means lowering the charging speed of the returned battery. For example, the three charging levels of the returned battery mentioned above are fast charging, sub-fast charging and slow charging, and the charging speeds of these three charging levels decrease successively, which means that the three charging levels are reduced successively.

[0112] It is understandable that when the environmental parameters of the returned battery are within the warning range, charging the returned battery at a higher charging speed may cause dangerous situations such as battery overheating, short circuit and thermal runaway. Therefore, in order to avoid danger in the battery charging process, the charging level of the returned battery can be reduced.

[0113] In some embodiments, Figure 7 As shown, after step S172, the charging scheduling method further includes step S173 and step S174.

[0114] Step S173, monitoring the environmental parameters after the charging level of the returned battery is reduced, and if the environmental parameters are still within the warning range, repeatedly reducing the charging level of the returned battery until the environmental parameters are within the normal range or the charging level reaches the minimum charging level;

[0115] Step S174: After the charging level reaches the minimum charging level, monitor whether the environmental parameters are within the warning range, and if so, stop charging the returned battery.

[0116] It can be understood that if lowering the charging level of the returned battery can make the environmental parameters tend to be within the normal range, it means that lowering the charging speed of the returned battery can improve the environmental parameters. Similarly, if lowering the charging level of the returned battery cannot make the environmental parameters tend to be within the normal range, it means that lowering the charging speed of the battery cannot improve the environmental parameters. In order not to damage the battery, the charging of the returned battery can be stopped at this time to ensure the safety of the returned battery.

[0117] In some embodiments, Figure 8 As shown, after step S140, the charging scheduling method further includes step S180.

[0118] Step S180: monitor the environmental parameters during the charging process of the returned batteries. If the environmental parameters are within the warning range, reduce the number of returned batteries with the highest charging level.

[0119] It is understandable that if the environmental parameters of the returned battery when being charged are monitored to be within the warning range, since the higher the charging level of the battery, the higher the charging risk of the battery, the number of batteries with the highest charging level can be reduced to ensure that fewer batteries are in a dangerous charging state.

[0120] In addition, it is understandable that the higher the battery charging level, the faster the battery temperature rises. If the environmental parameter is the battery temperature, the more batteries with the highest charging level, the higher the battery temperature will be, thereby making the charging environment of the user's battery worse. At this time, reducing the number of batteries with the highest charging level can effectively improve the environment of the returned batteries.
