The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
The present embodiment provides a charge control method, as shown in fig. 1, including:
step 101, predicting a battery supply state and a battery replacement demand of the target battery replacement station in a first time period.
The first time period is a future preset time period, and the range of the first time period may be determined according to actual requirements, for example, the first time period may be a day specifically, or the first time period may also be a business time period of the target battery exchange station in a day. In this embodiment, future power change data may be predicted specifically based on historical power change data of the target power change station, or power change data in a period after a current or future period may be predicted based on power change data in the period. In a specific implementation, as shown in fig. 2, step 101 may specifically predict by:
step 1011, obtaining a battery supply state and a battery replacement requirement of a target battery replacement station in a second time period;
step 1012, predicting the battery supply status and the battery replacement demand of the target battery replacement station in the first time period according to the battery supply status and the battery replacement demand in the second time period.
Wherein the second time period is a time period before the first time period.
In this embodiment, future data (i.e., the battery supply state and the battery replacement requirement in the first time period) may be predicted according to historical data (i.e., the battery supply state and the battery replacement requirement in the second time period) of the target battery exchange station, where the historical data may be obtained by data such as a battery exchange log of the target battery exchange station, and the second time period may be the same as or longer than the first time period. For example, if it is desired to predict the predicted data for the next day, historical data for a week prior to the next day may be obtained, averaged, or other predetermined calculation method to obtain the predicted data for the next day. The historical data of the target power exchange station can be used for fully utilizing the self resources, and the prediction accuracy is improved. In other alternative embodiments, in the absence of historical data for the target station, etc., historical data for other types or locations of nearby stations may also be selected for predicting battery replacement needs for the target station.
And 102, performing charging control on the battery of the target battery replacement station according to the battery supply state and the battery replacement requirement.
When the battery supply state of the first time period is predicted to meet the battery replacement requirement, the battery can not be charged in advance, and when the battery supply state of the first time period is predicted to not meet the battery replacement requirement, the battery of the target battery replacement station is charged in advance, so that the battery supply state meets the battery replacement requirement.
In this embodiment, unlike the passive charging mode in which the battery of the battery exchange station is charged immediately after the battery exchange, the present embodiment performs active charging control on the battery of the battery exchange station according to the future battery exchange requirement, specifically predicts the battery supply state and the battery exchange requirement of the target battery exchange station in the first time period in the future, and performs charging control on the target battery exchange station according to the prediction result in the future. On the one hand, the charging resource can be saved under the condition of meeting the battery supply requirement, and on the other hand, the condition that the batteries which are replaced in a concentrated mode are required to be charged in the power conversion peak period can be avoided, and the charging pressure of the power conversion station is reduced.
Specifically, in this embodiment, the batteries in the target battery exchange station include an available battery and a battery to be charged, where the available battery is a battery whose remaining capacity reaches a capacity threshold, and the battery to be charged is a battery whose remaining capacity does not reach the capacity threshold, and the specific value of the capacity threshold may be determined according to the actual situation, for example, 98% of the full capacity of the battery may be generally used as the capacity threshold. The battery replacement requirements of the target power exchange station include: the number of batteries to be replaced, the battery supply state includes: the number of available batteries, in step 102, it may be determined whether the battery supply status satisfies the battery replacement requirement by comparing the number of available batteries and the number of batteries to be replaced, specifically:
when the number of available batteries does not meet the number of batteries to be replaced (at this time, the battery supply state does not meet the battery replacement requirement), the batteries to be charged are charged in advance so that the batteries to be charged are converted into available batteries until the number of available batteries meets the number of batteries to be replaced (at this time, the battery supply state can meet the battery replacement requirement). When the number of available batteries satisfies the number of batteries to be replaced (the battery supply state can satisfy the battery replacement requirement at this time), the batteries to be charged do not need to be charged in advance.
The determining whether the number of available batteries satisfies the number of batteries to be replaced may determine that the number of available batteries satisfies the number of batteries to be replaced when the number of available batteries is greater than or equal to the number of batteries to be replaced. And when the number of available batteries is smaller than the number of batteries to be replaced, confirming that the number of available batteries does not satisfy the number of batteries to be replaced.
However, since the predicted battery replacement requirement and the battery supply status are not necessarily identical to the actual battery replacement requirement, in a preferred embodiment, when the number of available batteries is greater than or equal to the sum of the number of batteries to be replaced and the preset additional number, the number of available batteries is confirmed to satisfy the number of batteries to be replaced, that is, the battery supply status is confirmed to be able to satisfy the battery replacement requirement in step 102. And when the number of the available batteries is smaller than the sum of the number of the batteries to be replaced and the preset additional number, confirming that the number of the available batteries does not meet the number of the batteries to be replaced, namely, confirming that the battery supply state cannot meet the battery replacement requirement.
Through setting up extra quantity battery and charging in advance, can lead to when prediction data and actual data disagree like battery damage, have emergency such as extra battery demand, the target battery that trades can have extra available battery to satisfy the requirement of changing electricity, avoid the user to wait for battery charging when changing the electricity, improve user's the experience of changing electricity. The preset additional quantity can be set according to actual requirements, for example, the data of the historical emergency of the target power exchange station can be calculated in a statistics mode.
In this embodiment, the number of batteries to be replaced and the number of available batteries in the first time period are specifically predicted, based on this, if the number of available batteries cannot meet the number of batteries to be replaced, the battery to be charged can be charged in advance, so as to ensure that the number of available batteries in the first time period can meet the number of batteries to be replaced in the first time period, thereby meeting the battery supply requirement in the first time period.
In this embodiment, only when the number of available batteries is predicted to be unable to meet the number of batteries to be replaced, the batteries to be charged need to be charged in advance, so that the power supply requirement of the first time period is met, and meanwhile, charging resources are further saved.
In step 102, the battery of the target battery exchange station may be controlled by determining the charging start time and/or the charging speed of the battery to be charged in the target battery exchange station, so as to control the time for converting the charging of the battery to be charged into the available battery, so as to meet the available battery requirement at each time point in the first time period.
Specifically, the battery supply state further includes a remaining power of the battery to be charged, and as shown in fig. 3, step 102 specifically includes the following steps to calculate a charging start time and/or a charging speed of the battery to be charged:
step 1021, determining the number of the batteries to be charged in advance according to the number of the available batteries and the number of the batteries to be replaced;
step 1022, calculating the required electric quantity converted into the usable battery according to the residual electric quantity of the battery to be charged;
step 1023, calculating the early charge start time and/or the charge speed according to the required electric quantity.
Steps 1021-1023 are described below by way of a specific example to facilitate understanding:
if it is determined in step 101 that the number of available batteries is 2 and the number of batteries to be replaced is 4, it may be determined in step 1021 that 2 batteries need to be charged in advance, assuming that the target battery exchange station has a total of 3 batteries to be charged at that time, wherein the remaining power of the first battery is 20%, the remaining power of the second battery is 50%, the remaining power of the third battery is 80%, and the remaining power of the available battery is 90%, whereby it may be calculated in step 1022 that the required power of the first battery is 70%, the required power of the second battery is 40%, and the required power of the third battery is 10%. The two batteries can be randomly selected for pre-charging, and can be selected according to a preset rule, such as the preferential charging of the battery with low required electric quantity. The embodiment specifically adopts a mode of preferential charging of the battery with low required electric quantity to exemplify that the second battery and the third battery in the three batteries are selected for advanced charging.
In step 1023, the charging start time and/or the charging speed are calculated according to the respective required amounts of the two batteries, and the required amount of the second battery is 40% as an example. If only the charging start time is considered, the time T1 required by 40% to 90% of the electric quantity can be calculated based on the preset charging speed, and the second battery can be charged in advance by T1 with the time at which the first time period starts as a node; if only the charging speed is considered, the time when the second battery is replaced can be taken as the time when charging starts, the time when the first time period starts can be taken as the time when charging ends, the charging time can be obtained by subtracting the two times, and the required average charging speed can be calculated according to the required 50% of the electric quantity and the charging time. If the charging start time and the charging speed are considered at the same time, the busy condition of the power exchange station can be comprehensively considered, for example, the charging is controlled to be carried out at a lower charging speed (for example, lower power is output) in a period of busy charging, or the charging is not carried out in a period of busy charging; as another example, the battery is not charged or is not charged enough in a time period in which the electricity price is high.
In this embodiment, the battery supply state further includes a remaining capacity of the battery to be charged, and when the number of available batteries does not satisfy the number of batteries to be replaced, a required electric capacity for converting the remaining capacity of the battery to be charged into the available battery can be calculated based on the remaining capacity of the battery to be charged, so that a charging start time and/or a charging speed required to charge the battery to be charged in advance can be calculated, and charging is performed at a corresponding speed at the corresponding charging start time, so as to ensure that the number of available batteries of the target battery to be replaced in the first time period can satisfy the battery replacement requirement.
In this embodiment, based on the prediction of the battery supply state and the battery replacement requirement in the first time period, the charging start time and/or the charging speed of the battery to be charged in the target battery replacement station are determined so as to perform charging control on the battery to be charged, thereby ensuring that the available battery in the first time period can meet the battery replacement requirement in the first time period.
In a preferred embodiment, as shown in fig. 4, the charge control method may further include the steps of:
step 103, acquiring the actual power change condition of the target power change station in the first time period in real time;
and 104, adjusting the charging control according to the actual power change condition.
In this embodiment, the actual power change condition in the first time period may be obtained, and the charging control mode of the target power change station may be further adjusted based on the actual power change condition, so as to prevent the user from being affected when the prediction of the battery replacement requirement is inaccurate. The actual power change condition may include the actual available battery number, the actual battery to be changed, and the like. And the actual power change condition of the first time period can be used as the second time period of the time period after the first time period, so that the charging control mode can be further adjusted according to the actual power change condition and the predicted power change condition, and the charging control of the power change station is more in accordance with the actual requirement and has practicability.
In a preferred embodiment, the target battery exchange station includes batteries of different types, and step 101 specifically predicts battery supply states and battery replacement requirements corresponding to the batteries of different types of the target battery exchange station in the first time period.
Step 102 specifically includes: and respectively controlling the charging of the batteries of different types in the target battery exchange station according to the battery supply states and the battery exchange requirements of the batteries of different types.
In this embodiment, since the target power exchange station may include batteries of different types in actual situations, in this embodiment, for each type of battery, the corresponding battery supply state and the corresponding battery replacement requirement can be predicted, and based on this, charging control is performed for the batteries of different types, so as to ensure that the target power exchange station can meet the requirements of the power exchange vehicle using the batteries of different types.
