Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] The control method of the energy storage cabinet is applied to electric vehicle charging technology. The energy storage cabinet stores multiple energy storage units, including batteries. After receiving the customer's order information, the staff selects multiple energy storage units to form a battery pack according to the order information and pushes the battery pack out of the energy storage cabinet. The battery pack is placed in a trolley. The staff pushes the trolley to the location of the customer's vehicle and connects the battery pack to the vehicle through the charging equipment to realize the charging of the electric vehicle.

[0048] The inventive concept of this application is as follows: After receiving a customer's charging order, the energy storage cabinet classifies the energy storage units in the cabinet according to the order information and multiple parameter information of the energy storage units, sets priorities, selects energy storage units that are suitable for the charging order and can be charged efficiently according to the classification results, and pushes the energy storage units into a battery pack out of the energy storage cabinet so that the staff can take the appropriate charging battery pack to charge the car, thereby achieving efficient service.

[0049] Figure 1 A flowchart of a control method for an energy storage cabinet provided in an embodiment of this application is shown below. Figure 1 As shown, the control method for this energy storage cabinet includes the following steps:

[0050] S101. Obtain the user's identity information and determine the order information served by the user based on the user's identity information.

[0051] More specifically, obtaining user identity information includes: installing cameras on the energy storage cabinet, the server obtaining facial images of the staff taken by the cameras on the energy storage cabinet, recognizing the staff's faces, and determining the order information of the staff's current order, wherein the order information includes the target electricity volume.

[0052] S102. Based on the target power and the parameter information of each energy storage unit in the energy storage cabinet, determine the identifier of the energy storage unit to be retrieved.

[0053] More specifically, the server calculates and obtains multiple energy storage units based on the target power level and parameter information of each energy storage unit in the energy storage cabinet. It then determines the identifier of the energy storage unit to be retrieved. Each energy storage unit includes a battery, and its parameter information includes battery charge, battery health, voltage difference between actual and ideal output voltage, actual battery operating temperature, and temperature difference between actual and ideal operating temperature. The identification of the energy storage unit to be retrieved is determined based on the target power level and parameter information of each energy storage unit in the energy storage cabinet, specifically including:

[0054] The parameter information of each energy storage unit in the energy storage cabinet is used to classify each energy storage unit into different levels; and the energy storage units in the same level are sorted according to the parameter information of the energy storage units. The identifier of the energy storage unit to be retrieved is determined according to the sorting result of the energy storage units in each level.

[0055] S103. Based on the identification of the energy storage unit to be retrieved, control the grabbing device to grab the energy storage unit to be retrieved from the energy storage cabinet, and control the assembly device to assemble the energy storage unit to be retrieved in a stacked manner.

[0056] More specifically, based on the identifier of the energy storage unit to be retrieved, the server controls the grasping device to grasp the energy storage unit to be retrieved from the energy storage cabinet, and controls the assembly device to assemble the energy storage unit to be retrieved in a stacked manner. The grasping device includes a robotic arm, and the assembly method includes a stacking assembly method.

[0057] For example: Figure 2 A structural diagram illustrating the control of the grasping device in grasping the energy storage unit in the energy storage cabinet is shown below. Figure 2 As shown, the structure for controlling the grasping device to grasp energy storage units in the energy storage cabinet includes a robotic arm 21, an energy storage cabinet 22, and energy storage units 23. The energy storage cabinet 22 contains multiple energy storage units 23. Based on the identifier of the energy storage unit 23 to be retrieved, the server controls the robotic arm 21 to grasp the energy storage unit 23 to be retrieved from the energy storage cabinet 22, and controls the assembly device to assemble the energy storage units 23 to be retrieved in a stacked assembly manner.

[0058] In the energy storage cabinet control method provided in this application embodiment, the target power of the order information is obtained through facial recognition. Based on the order information and the parameter information of the energy storage units in the energy storage cabinet, the energy storage units are classified into different levels, and then sorted according to the classified energy storage units to determine their priority, thereby determining the energy storage unit to be retrieved. Facial recognition improves the efficiency and portability of obtaining order information, and classifying and sorting the energy storage units to determine their priority enables the energy storage cabinet to more effectively match customers with more suitable battery packs, improving service quality and charging experience.

[0059] Figure 3 A flowchart of a control method for an energy storage cabinet provided in an embodiment of this application is shown below. Figure 3 As shown, the method provided in this embodiment is the specific steps for classifying each energy storage unit according to the parameter information of each energy storage unit in the energy storage cabinet in step S102, as follows:

[0060] S301. Determine whether the parameter information of the energy storage unit meets the level conditions and determine the level classification of the energy storage unit.

[0061] More specifically, the energy storage unit is classified into three categories: Class I, Class II, and Class III. If the parameter information of an energy storage unit meets the requirements of a certain category, the energy storage unit is determined to be of that category. As shown in Table 1, these are the requirements for the energy storage unit's classification.

[0062] For example, when the parameter information of the energy storage unit meets the first-class conditions, that is, the battery charge of the energy storage unit is greater than 95%, the battery health is greater than 95%, the voltage difference between the actual output voltage and the ideal output voltage is greater than the first threshold y, the actual battery operating temperature is between 15 degrees Celsius and 30 degrees Celsius, and the temperature difference between the actual battery operating temperature and the ideal operating temperature is greater than the second threshold x, then the energy storage unit can be determined as a first-class energy storage unit.

[0063] When the parameter information of the energy storage unit meets the conditions of the second category, that is, the battery charge of the energy storage unit is between 80 and 95, the battery health is between 90 and 95, the voltage difference between the actual output voltage and the ideal output voltage is greater than the product of the first threshold y and the first weight, the actual battery operating temperature is between 5 degrees Celsius and 15 degrees Celsius or between 30 degrees Celsius and 40 degrees Celsius, and the temperature difference between the actual battery operating temperature and the ideal operating temperature is greater than the sum of the second threshold x and the first upward value, then the energy storage unit can be determined as a second category energy storage unit. Here, the first weight includes the value 3, and the first upward value includes the value 3.

[0064] When the parameter information of the energy storage unit meets the conditions of the third category, that is, the battery charge of the energy storage unit is less than 80%, the battery health is between 85 and 90%, the voltage difference between the actual output voltage and the ideal output voltage is greater than the product of the first threshold y and the second weight, the actual battery operating temperature is less than 5 degrees Celsius or greater than 40 degrees Celsius, and the temperature difference between the actual battery operating temperature and the ideal operating temperature is greater than the sum of the second threshold x and the second upward value, the energy storage unit can be determined to be a third category energy storage unit. The second weight includes the value 5, and the second upward value includes the value 7.

[0065] Table 1 Level Conditions

[0066]

[0067] S302. The difference between the parameter information of the energy storage unit and the condition threshold is summed, and the difference sum is compared to determine the level classification of the energy storage unit.

[0068] More specifically, when the parameter information of the energy storage unit does not meet the conditions for the first, second, and third categories, the difference between the parameter information of the energy storage unit and the condition threshold is calculated and summed. By comparing the sum of the differences, the category of the energy storage unit is then determined.

[0069] For example: calculate the difference between each parameter in the energy storage unit's parameter information and the condition threshold in the first category of conditions, and then sum them to obtain the first difference sum; calculate the difference between each parameter in the energy storage unit's parameter information and the condition threshold in the second category of conditions, and then sum them to obtain the second difference sum; calculate the difference between each parameter in the energy storage unit's parameter information and the condition threshold in the third category of conditions, and then sum them to obtain the third difference sum; select the smallest difference sum from the first difference sum, the second difference sum, and the third difference sum as the corresponding category of the energy storage unit's category.

[0070] S303. Determine whether the parameter information of each energy storage unit meets the conditions of each level, and determine the level classification of the energy storage unit.

[0071] More specifically, when the parameter information of an energy storage unit does not meet the conditions for the first, second, and third categories, it is determined whether the parameter information of each energy storage unit meets the conditions for each category, and the category of the energy storage unit is determined.

[0072] For example: if the parameter information of the energy storage unit does not meet the first, second and third level conditions, determine whether the battery charge of the energy storage unit meets any one of the first, second and third level conditions. If it does, determine the level of the energy storage unit according to the level condition met.

[0073] If none of them are met, then continue to determine whether the battery health meets any one of the first, second and third level conditions. If it does, then determine the level of the energy storage unit based on the level condition met.

[0074] If none of them are met, then continue to determine whether the voltage difference meets any one of the first, second and third level conditions. If it does, then determine the level of the energy storage unit based on the level condition met.

[0075] If none of them are met, then it is determined whether the actual operating temperature of the battery meets any one of the first, second and third level conditions. If it does, the level of the energy storage unit is determined according to the level condition met.

[0076] If none of the conditions are met, then it is determined whether the temperature difference meets any one of the first, second, or third grade conditions. If it does, the grade of the energy storage unit is determined based on the grade condition met.

[0077] In the energy storage cabinet control method provided in this application embodiment, by setting a classification table of the level conditions of various parameters of the energy storage unit, and classifying the energy storage unit according to this table, the control method can reasonably classify the energy storage unit according to the priority of the parameters when the energy storage unit fully meets the level conditions or does not fully meet the level conditions of various parameters, thereby improving the compatibility between the acquired battery and the user, improving charging efficiency and user experience, and selecting the optimal battery charging scheme to save the user's charging time as much as possible.

Figure 4 As shown, the method provided in this embodiment involves the specific steps of sorting energy storage units in the same level according to their parameter information in step S102, and determining the identifier of the energy storage unit to be retrieved based on the sorting result of the energy storage units in each level, as follows:

[0079] S401. For each type of energy storage unit, determine whether there are multiple energy storage units in the same type of energy storage unit whose battery charge is greater than the target charge.

[0080] More specifically, for each type of energy storage unit, it is determined whether there are multiple energy storage units in the same type whose combined battery charge is greater than the target charge. If so, the identifiers of the multiple energy storage units whose combined battery charge is greater than the target charge are used as the identifiers of the energy storage units to be retrieved.

[0081] S402. Classify each energy storage unit according to the parameter information of each energy storage unit in two adjacent energy storage cabinets.

[0082] More specifically, if it is determined that there are no multiple energy storage units in the same type of energy storage unit whose total battery charge is greater than the target charge and whose sorting positions are consecutive, the energy storage units are classified according to the parameter information of each energy storage unit in two adjacent energy storage cabinets.

[0083] S403. Determine the identifier of the energy storage unit to be retrieved based on the sorting result of the energy storage units in each level.

[0084] More specifically, energy storage units in the same level are sorted according to their parameter information, and the identifier of the energy storage unit to be retrieved is determined based on the sorting results of the energy storage units in each level.
