Detailed Description
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
It should be noted that, without conflict, the following embodiments and features in the embodiments may be combined with each other; and, based on the embodiments in this disclosure, all other embodiments that may be made by one of ordinary skill in the art without inventive effort are within the scope of the present disclosure.
It is noted that various aspects of the embodiments are described below within the scope of the following claims. It should be apparent that the aspects described herein may be embodied in a wide variety of forms and that any specific structure and/or function described herein is merely illustrative. Based on the present disclosure, one skilled in the art will appreciate that one aspect described herein may be implemented independently of any other aspect, and that two or more of these aspects may be combined in various ways. For example, an apparatus may be implemented and/or a method practiced using any number of the aspects set forth herein. In addition, such apparatus may be implemented and/or such methods practiced using other structure and/or functionality in addition to one or more of the aspects set forth herein.
In one aspect of the application, a power control system is provided that is applicable within a mobile charging device (e.g., a mobile charging vehicle or a mobile power source).
Referring to fig. 1, the electric energy control system provided by the present application includes: the device comprises an EEPROM memory, a data read-write module, an electric energy output module and a first electric energy recording module; the EEPROM memory is connected with the data read-write module, and the data read-write module and the electric energy output module are both connected with the first electric energy recording module. The data read-write module and the first electric energy recording module can be virtual modules formed by software programs, and can be hardware modules (such as a processor or a singlechip) for running preset software programs. The power output module may be a charging gun or other power output interface (e.g., USB interface).
The power control system is used for executing the following steps:
And S100, the first electric energy recording module responds to the received charging request and sends a historical electric quantity acquisition request to the data reading and writing module. The charging request may be sent by an external device to be charged (such as a new energy automobile), or may be sent by a controller in the mobile charging device where the electric energy control system is located in response to a request of the device to be charged.
S120, the data read-write module acquires a first historical electric quantity character string T1 and a second historical electric quantity character string T2 from the EEPROM memory, and sends the T1 and the T2 to the first electric energy recording module; t1 and T2 are m-bit binary integer strings. Specifically, m=16. I.e., T1 and T2 are each a string consisting of 16-bit binary numbers.
S130, the first electric energy recording module obtains a target historical electric quantity character string init=lift (T1, m) +t2 according to T1 and T2; wherein lift () is a preset displacement processing function for shifting T1 left by m bits. Shifting T1 left by 16 bits is a 32-bit string with T1 changed to 0 for the last 16 bits. Thus, INIT is a string of 32-bit binary numbers, with the upper 16 bits of the credit being T1 and the lower 16 bits being T2.
And S140, the first electric energy recording module acquires target historical electric quantity information LV=BIN 2DEC (INIT) Factor, and controls the electric energy output module to output electric energy, wherein BIN2DEC () is a preset system conversion function. Factor=0.01. Since the constant 10 system numbers are used in the process of displaying and counting the electric quantity, in this embodiment, the INIT is converted from 2 system numbers to 10 system numbers through LV=BIN 2DEC (), and since in this embodiment, the output electric quantity needs to be accurate to the last two decimal points, namely 0.01 kilowatt-hour, in the process of recording, the numerical conversion is performed on BIN2DEC (INIT) through a preset conversion coefficient Factor, so that finally accurate 10 system and accurate to 0.01 kilowatt-hour electric quantity recording is obtained.
S150, the first electric energy recording module updates LV to LV=LV+ZV every set period, and sends the updated LV to display equipment (such as a display) to enable the display equipment to update display content; wherein ZV is the output power corresponding to the current setting period, zv= ((Inow x Unow)/1000) x stepT/3600; wherein Inow is the current output current of the electric energy output module, unow is the current output voltage of the electric energy output module, and stepT is the time length of the set period. Wherein Inow is in amperes, unow is in volts, and stepT is in seconds, such that ZV is in kilowatt-hours. Specifically, in determining the specific value stepT, it may be determined according to the hardware performance of the mobile charging device, and theoretically, the smaller the value stepT, the more accurate. In this embodiment, stepT is 0.01 seconds, that is, the numerical value is updated every 0.01 seconds, and experiments show that most of the hardware performance of the mobile charging device can be compatible with the updating period of 0.01 seconds, and the accuracy rate reaches the application requirement.
It should be noted that, in the present application, after each charging is completed, the current LV is reconverted into T1 and T2 and updated into the EEPROM memory for the next charging. The specific conversion process may be the inverse operation of the step S130 and the step S130, which should be understood by those skilled in the art that the conversion and updating can be implemented by the disclosure of the present application, and details are not repeated herein.
The electric energy control system provided by the embodiment can realize periodic electric quantity recording output when external charging is performed each time by using software and hardware configuration (such as an EEPROM memory, a data read-write module, an electric energy output module and a first electric energy recording module) in the mobile charging vehicle. And the storage of historical data is carried out through the EEPROM, so that the accumulated record of multiple times of charging is realized. Therefore, the purpose that the recording and displaying of the output electric quantity are realized by moving the original software and hardware configuration in the charging vehicle without additionally installing a physical electric meter is achieved.
Meanwhile, since the configuration of hardware in the mobile charging vehicle is often low, for example, the storage space in the EEPROM memory is small. In the process of recording the electric quantity, the conventional unit is "kilowatt-hour", so that the accuracy of recording is at least one or two digits after decimal point. If the floating-point character string is stored in the EEPROM, the memory space occupied by the floating-point character string is twice that of the integer character string under the condition of the same bit number. Therefore, in this embodiment, two binary integer strings of m bits (i.e., T1 and T2) are stored and recorded, and the target historical power information finally used for recording and displaying is obtained through processing and calculating the T1 and T2, and the target historical power information can be displayed to a numerical value after a decimal point. Therefore, on one hand, the recorded data can meet the application requirements, and on the other hand, the occupation of the storage space of the EEPROM memory is reduced.
In one exemplary embodiment of the application, the power control system further comprises a second power recording module; and the second electric energy recording module is connected with the data reading and writing module and the electric energy output module at the same time.
The power control system is further configured to perform the steps of:
S200, the second electric energy recording module responds to the received charging request and sends a user history electric quantity acquisition request to the data reading-writing module; the user history electric quantity acquisition request comprises a user ID of a user corresponding to the charging request.
S210, the data read-write module acquires a first user electric quantity character string YT1 and a second electric quantity character string YT2 corresponding to the user ID from an EEPROM memory, and sends the YT1 and the YT2 to the second electric energy recording module; YT1 and YT2 are both m-bit binary integer strings.
And S230, the second electric energy recording module acquires a user electric quantity character string YINIT =lift (YT 1, m) +YT2 according to YT1 and YT2.
S240, the second power recording module obtains user history power information YLV =bin 2DEC (YINIT) Factor.
S250, the second electrical energy recording module obtains the current charge amount yb=0 of the user.
S260, the second electrical energy recording module obtains yb=yb+zv and YLV = YLV +zv at intervals of a set period.
In this embodiment, it may be understood that the second virtual electric meter is configured through the second electric energy recording module to record the current charging electric quantity and the historical total charging electric quantity that individually correspond to the user who charges this time. And the specific method used is the same as that of the previous embodiment.
The electric energy control system provided by the embodiment can set corresponding virtual electric meters according to requirements, and is used for recording electric quantity under different scenes and requirements. Therefore, the electric quantity statistics under multiple dimensions can be completed without additionally installing multiple electric meters, on one hand, the hardware cost is saved, on the other hand, the universality of the electric energy control system can be improved, and the electric energy control system can be expanded and set at any time according to actual conditions.
Accordingly, in other embodiments, the charged electric quantity of the mobile charging device can be recorded and stored in the EEPROM memory. Therefore, the staff can determine the charge-discharge ratio of the mobile charging equipment or the self-running energy consumption through the total number of the historically charged electric quantity and the total number of the historically output electric quantity, and the mobile charging equipment is more convenient to optimize according to the data.
In an exemplary embodiment of the application, a first list and a second list are provided in the EEPROM memory, T1 being stored in the first list and T2 being stored in the second list; and the storage location of T1 in the first list is the same as the storage location of T2 in the second list.
In this embodiment, T1 and T2 are respectively stored in different lists, so that if an unauthorized user obtains the EEPROM memory by himself, he cannot directly obtain the historical working (charging and discharging) condition of the mobile charging device where he is located through the data stored in the EEPROM memory, thereby improving the security of information. And compared with the method for encrypting the internal data, the method does not occupy a large amount of calculation amount.
In an exemplary embodiment of the present application, after the step S150, the method further includes:
S160, responding to each update of the LV, adding the currently acquired ZV as a judgment value to the tail of a preset unidirectional queue, and performing cycle length update processing; the unidirectional queue is a first-in first-out queue, and the maximum capacity of the unidirectional queue is n.
The cycle length update process includes the steps of:
S161, obtaining each judgment value in the current unidirectional queue to obtain a judgment value list P= (P1, P2, …, pi, …, pn); pi is the i-th judgment value in the current unidirectional queue. In this embodiment, n=10.
S162, obtaining the electric quantity fluctuation valueWherein avg () is a preset average value determination function. The smaller BD, the smaller the power fluctuation of the output electric quantity is explained.
S163, if BD < α, then stepT = stepT/β; otherwise, let stepT = β x stepT; wherein alpha is a preset judgment threshold value, 0 < alpha, beta is a preset adjustment coefficient, and 0 < beta < 1. In this embodiment, β=0.9. The specific value of alpha can be determined by a person skilled in the art according to actual requirements.
From the foregoing embodiments, it can be seen that in the present application, the update of the LV is performed every stepT. Whereas to ensure data accuracy, the stepT value is often set to be small, such as 0.01 seconds. However, this also increases the computational load on the processor and increases the computational pressure. However, it is found through experiments that when the power fluctuation of the output electric quantity is small, the obtained recording result meets the application requirement even if the value of stepT is increased. Therefore, in this embodiment, by recording the output power corresponding to the current set period when updating each time, determining the power fluctuation of the power output in the near n periods according to step S162, and actively increasing stepT when the fluctuation is small (i.e., BD < α), so as to reduce the updating frequency, thereby reducing the throughput. Otherwise, stepT is actively reduced to ensure the accuracy of recording.
Further, in order to avoid stepT unlimited reductions, in this embodiment, if β× stepT is less than 0.005, stepT =0.005.
Furthermore, although the steps of the methods in the present disclosure are depicted in a particular order in the drawings, this does not require or imply that the steps must be performed in that particular order, or that all illustrated steps be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform, etc.
