Technical Field

[0001] This invention relates to the field of energy storage technology, and in particular to a power adjustment method, device, electronic device, storage medium, and program product. Background Technology

[0002] To charge the batteries of two-wheeled or three-wheeled vehicles, battery swapping equipment, such as charging cabinets and battery swapping cabinets, is equipped with different numbers of chargers and high-voltage power lines of varying thicknesses.

[0003] With the increasing demand for charging, chargers in battery swapping equipment are evolving from one charger per charging port to one charger with multiple charging ports, also known as multi-port chargers. For the same total power, the output power of each channel in a multi-port charger is much higher than that of a single charger, resulting in greater efficiency.

[0004] In related technical solutions, although the battery swapping equipment uses a one-to-many charger, in actual charging, it employs an average power distribution scheme to charge the batteries to be charged. This charging method cannot ensure that the batteries to be charged are ready for use as quickly as possible, and therefore cannot meet the current battery swapping needs. Summary of the Invention

[0020] Wherein, the first power is the difference between the total required power and the maximum output power of the target charger.

[0022] The first battery to be charged is marked with a first identifier, which indicates that the first battery to be charged is not at full power; and / or

[0023] The target charger is marked with a second identifier, which indicates that the target charger is at full power output.

[0024] According to the power adjustment method provided by the present invention, when the charging power of the first battery to be charged is zero, a first reason for stopping charging is marked for the first battery to be charged.

[0027] At least a portion of the charging demand power in the charging power list are superimposed to obtain the demand power of the battery swapping device, wherein the demand power of the battery swapping device is the sum of the total demand power of all chargers;

[0028] Since the required power is greater than the rated power of the battery swapping equipment, the charging power of the target battery to be charged is reduced.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] The terms "first," "second," etc., used in this invention are used to distinguish similar objects, not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0050] The following is combined Figures 1-3 The present invention describes a power adjustment method, apparatus, electronic device, storage medium, and program product, which aims to match the total power demand to the maximum output power of the target charger by reducing the charging power of at least one battery to be charged using a target charger. In this process, the battery to be charged can be used as quickly as possible, thereby meeting the current battery swapping needs.

[0051] Figure 1 This is one of the flowcharts illustrating the power adjustment method provided by the present invention. The battery swapping equipment includes at least one charger, each charger being used to charge at least one battery to be charged, such as... Figure 1 As shown, the power adjustment method includes, but is not limited to, the following steps:

[0052] Step 101: Obtain the charging power list, which includes the charging power requirement of each battery to be charged.

[0053] The charging power requirement can be understood as the charging power that the charger should provide when charging the battery.

[0054] Step 102: At least a portion of the charging power demand in the charging power list are superimposed to obtain the total power demand of the target charger, which is one of at least one charger.

[0055] The process of superimposing at least a portion of the charging power demand in the charging power list can be understood as summing at least a portion of the charging power demand in the charging power list. By calculating the charging power demand of the batteries connected to each charger, the total power demand of each charger is obtained.

[0056] Step 103: Based on the fact that the total power demand is greater than the maximum output power of the target charger, reduce the charging power of at least one battery to be charged using the target charger.

[0057] In this embodiment, the charging power demand in the charging power list is superimposed to obtain the total power demand of each charger in the battery swapping device. Then, when the total power demand is greater than the maximum output power of the target charger, the charging power of at least one battery to be charged using the target charger is reduced to match the total power demand with the maximum output power of the target charger. In this process, the battery to be charged can be used as quickly as possible, thereby meeting the current battery swapping needs.

[0058] In some embodiments, a charging power list is obtained, which includes the charging power requirement for each battery to be charged, specifically including:

[0059] Get the charging list of batteries to be charged. The charging list includes the SOC value of each battery to be charged and the charging attributes corresponding to each battery to be charged. The charging attributes include the charger used by the battery to be charged and the charging channel occupied by the battery to be charged.

[0060] The corresponding charging power requirement is determined based on the SOC value of each battery to be charged.

[0061] The charging power list is determined based on the charging power requirement and charging list for each battery to be charged.

[0062] In this embodiment, the charging power of the battery to be charged is not constant, but changes dynamically with the SOC value. Therefore, when obtaining the charging power list, it is necessary to first obtain the SOC value of each battery to be charged, and then determine the corresponding charging power requirement based on the SOC value of the battery to be charged.

[0063] Furthermore, by obtaining the charging attributes corresponding to each battery to be charged, the charger and corresponding charging channel used by each battery to be charged can be known based on the charging attributes. This allows the total power demand of each charger to be known when at least some of the charging demand power in the charging power list is superimposed.

[0064] Based on this, a charging power list is determined according to the charging power requirement and charging list corresponding to each battery to be charged.

[0065] In some embodiments, the batteries to be charged in the charging power list are represented as follows:

[0066] {B[n][c]|0≤n≤N, 0≤c≤Cn};

[0067] Where B[n][c] represents the battery to be charged connected to the c-th charging channel of the n-th charger, N represents the number of chargers, and Cn represents the number of charging channels of the n-th charger.

[0068] In some embodiments, the State of Charge (SOC) value refers to the current state of charge of the battery, representing the proportion of electrical energy stored in the battery to its total capacity, typically expressed as a percentage.

[0069] In some embodiments, based on the total power demand exceeding the maximum output power of the target charger, the charging power of at least one battery to be charged using the target charger is reduced, specifically including:

[0070] Based on the fact that the total power demand is greater than the maximum output power of the target charger, the SOC value of each battery to be charged in the candidate battery set is obtained, where the candidate battery set is a set of batteries to be charged using the target charger.

[0071] Based on the sorting results of the SOC values ​​of each battery to be charged from smallest to largest, the batteries to be charged in the candidate battery set are sorted to obtain the sorting results;

[0072] Based on the sorting results, reduce the charging power of the batteries to be charged in the candidate battery set until the output power of the target charger equals the maximum output power.

[0073] In this embodiment, the SOC values ​​of different batteries to be charged are used to sort the batteries in the candidate battery set and obtain a sorting result. This result can be used to characterize the order in which the batteries to be charged are selected when the charging power is reduced, so as to ensure that the batteries with larger SOC values ​​can continue to be charged, while the charging power is reduced for the batteries with smaller SOC values, so as to ensure that the batteries to be charged can be used as quickly as possible, thereby meeting the current battery swapping needs.

[0074] Specifically, the sorting result is the ranking of the candidate battery set when the SOC values ​​of the batteries to be recharged are sorted from smallest to largest.

[0075] For example, the candidate battery set includes battery 01, battery 02, and battery 03 to be recharged. The SOC value of battery 01 is 15%, the SOC value of battery 02 is 95%, and the SOC value of battery 03 is 75%. The order of the SOC values ​​of the batteries to be recharged from smallest to largest is 15%, 75%, and 95%, and the order is battery 01, battery 03, and battery 02. When reducing the charging power of the batteries to be recharged in the candidate battery set, the charging power of the batteries to be recharged is reduced according to battery 01, battery 03, and battery 02.

[0076] In some embodiments, the candidate battery set includes a first battery to be charged, and the first battery to be charged is the battery to be charged with the smallest SOC value; according to the sorting result, the charging power of the batteries to be charged in the candidate battery set is reduced until the output power of the target charger is equal to the maximum output power. Specifically, it includes:

[0077] Based on the charging power of the first battery to be charged, reduce the first power;

[0078] Wherein, the first power is the power difference between the total required power and the maximum output power of the target charger.

[0079] In this embodiment, the battery to be charged with the smallest SOC value is preferentially selected to reduce the charging power, so as to ensure that the battery to be charged meets the use requirements fastest, and further meet the current battery replacement requirements.

[0080] Exemplarily, the charging power list is represented by {P[K]}, where K represents the number of batteries to be charged. Then, at least part of the charging demand powers in the charging power list are superimposed to obtain P1[m] (m < K), m represents the number of superimposed charging demand powers, and P1[m] represents the charging power of the battery replacement device.

[0081] Exemplarily, if the target charger is the k-th charger, then is used to represent the total required power of the k-th charger, represents the maximum output power of the k-th charger, then:

[0082] > ;

[0083] Then P[m] = P[m] - ( );

[0084] Wherein, can be understood as the power value that needs to be reduced by the k-th charger, that is, P[m] is updated by means of assignment.

[0085] In some embodiments, when the charging power of the first battery to be charged is less than the first power, then according to the sorting result, the charging powers of the batteries to be charged in the candidate battery set are superimposed. When it is determined that the superimposed result is greater than the first power, the charging power of the selected battery to be charged in the candidate battery set is reduced so that the power difference between the total required power and the maximum output power of the target charger is zero.

[0086] In some embodiments, after reducing the first power based on the charging power of the first battery to be charged, the power adjustment method further includes:

[0087] The first battery to be charged is marked with a first identifier, which indicates that the first battery to be charged is not at full power; and / or

[0088] The target charger is marked with a second identifier, which is used to indicate that the target charger is at full power output.

[0089] When the charging power of the first battery to be charged is zero, mark the first reason for the charging stop for the first battery to be charged;

[0090] The first reason for stopping charging is used to indicate that charging has stopped due to power limitations.

[0091] In some embodiments, when the charging power of the first battery to be charged is zero, the first battery to be charged is marked with a third identifier, wherein the third identifier is used to indicate that charging has stopped due to a reduction in charging power.

[0092] For example, the first identifier is power derating.

[0093] For example, the third identifier is reduced credit limit and charging is suspended.

[0094] For example, the first reason for stopping charging can be denoted as a power limit, such as UNCHARGE_REASON_POWER_LIMIT.

[0095] In this embodiment, by labeling with a first identifier, a second identifier, and a third identifier, maintenance personnel can more clearly understand the status of each battery to be charged and the charger in the battery swapping equipment, thereby facilitating subsequent maintenance.

[0096] In some embodiments, the power adjustment method further includes:

[0097] At least a portion of the charging demand power in the charging power list is superimposed to obtain the demand power of the battery swapping equipment, which is the sum of the total demand power of all chargers.

[0098] Based on the fact that the required power is greater than the rated power of the battery swapping equipment, the charging power of the target battery to be charged is reduced.

[0099] The target battery to be charged is at least one battery to be charged using a battery swapping device.

[0100] In this embodiment, if the required power is greater than the rated power of the battery swapping device, the charging power of the target battery to be charged is reduced so that the required power matches the rated power of the battery swapping device. In this process, the battery to be charged can be used as quickly as possible, thereby meeting the current battery swapping needs.

[0101] For example, the power demand of the battery swapping equipment is... This indicates that the rated power of the battery swapping equipment is based on... If it means:

[0102] like > This reduces the charging power of the target battery to be charged.

[0103] At the same time, P[m] = P[m] - ( - ).

[0104] In some embodiments, after reducing the charging power of the target battery to be charged, the power adjustment method further includes:

[0105] The target battery to be charged is marked with a first identifier, which is used to indicate that the target battery to be charged is not fully charged.

[0106] If the charging power of the target battery is zero, mark the first reason for the charging stop.

[0107] The first reason for stopping charging is used to indicate that charging has stopped due to power limitations.

[0108] In some embodiments, the target battery to be charged includes a first battery to be charged. Based on the fact that the required power exceeds the rated power of the battery swapping device, the charging power of the target battery to be charged is reduced, specifically including:

[0109] Obtain the second power, which is the power difference between the required power and the rated power of the battery swapping equipment;

[0110] Based on the premise that the second power is greater than or equal to the first power, the reduction of the first power is cancelled, and the second power is reduced based on the charging power of the first battery to be charged.

[0111] In this embodiment, by selecting a larger power, that is, selecting the second power as the power reduction value of the first battery to be charged, the target charger can have spare power. In this case, it can be ensured that the battery to be charged can be charged to meet the usage requirements at the fastest speed.

[0112] In some embodiments, a charging power list is obtained in response to any of the following triggering actions;

[0113] Changes in the SOC value of the battery to be charged, the occurrence of battery swapping after opening the compartment, or abnormal charging stoppage.

[0114] In this embodiment, power allocation can be automatically performed in any of the following situations: a change in the SOC value of the battery to be charged, the opening of the battery compartment for battery swapping, or an abnormal stop in charging. This ensures that the battery to be charged can be charged to its maximum capacity as quickly as possible.

[0115] In some embodiments, the target charger can be of various types such as one-to-one, one-to-four, one-to-five, one-to-six, etc., and the total number of battery swapping compartments can be various types such as 6, 8, 10, 12, 15, 18, 30, etc., which can be selected according to the actual use scenario, and will not be elaborated here.

[0116] In some embodiments, when N equals 3 and Cn = 5, =3.3 kilowatts, The operating conditions of the power swapping equipment under the condition of 9 kW are shown in Table 1.

[0122] The determining module 202 is used to superimpose at least a portion of the charging demand power in the charging power list to obtain the total demand power of the target charger, wherein the target charger is one of at least one charger.

[0123] Processing module 203 is used to reduce the charging power of at least one battery to be charged using the target charger, based on the fact that the total demand power is greater than the maximum output power of the target charger.

[0124] In this embodiment, the charging power demand in the charging power list is superimposed to obtain the total power demand of each charger in the battery swapping device. Then, when the total power demand is greater than the maximum output power of the target charger, the charging power of at least one battery to be charged using the target charger is reduced to match the total power demand with the maximum output power of the target charger. In this process, the battery to be charged can be used as quickly as possible, thereby meeting the current battery swapping needs.
