Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The invention mainly aims at the problems that in the prior art, when the acquired battery parameters are stored in a flash memory, the battery parameters are possibly damaged due to the limitation of writing times of the flash memory, so that the judgment on the service condition of a battery is inaccurate, and the use safety and reliability of the battery are reduced, and provides a storage method of the stored battery parameters in an energy storage system.
The method for storing the parameters of the energy storage battery in the energy storage system comprises the steps of firstly determining the current state parameters of the energy storage battery, storing the current state parameters of the energy storage battery into a nonvolatile storage medium and a Memory in the energy storage system, judging whether the time interval between the current moment and the last time of storing the state parameters into a Flash Memory is smaller than a threshold value or not by a user, and storing the current state parameters into the Flash Memory if the time interval is not smaller than the threshold value. Therefore, when the state parameters of the energy storage battery are stored, the condition that the stored state parameters are damaged due to the limitation of the writing times of the flash memory medium is avoided, the integrity of the state parameters of the energy storage battery is effectively ensured, the accuracy and the reliability of the state detection of the energy storage battery are improved, and the user experience is improved.
The following describes a method for storing parameters of an energy storage battery in an energy storage system according to an embodiment of the present invention in detail with reference to the accompanying drawings.
Fig. 1 is a flow chart of a method for storing energy storage cell parameters in an energy storage system according to an embodiment of the invention.
As shown in fig. 1, the method for storing the parameters of the energy storage battery in the energy storage system according to the embodiment of the invention may include the following steps:
step 101, determining the current state parameter of the energy storage battery.
Specifically, the method for storing the parameters of the energy storage battery in the energy storage system provided by the embodiment of the invention can be executed by the device for storing the parameters of the energy storage battery in the energy storage system, and the device can be configured in electronic equipment to control or manage the state parameters of the energy storage battery.
The state parameters of the energy storage battery in this embodiment may include: residual capacity, voltage, current, internal resistance, temperature, etc.
In particular, the current state parameters of the energy storage battery can be obtained through a voltage sensor, a current sensor, a temperature sensor and the like, and the invention is not particularly limited in this respect.
Step 102, storing the current state parameters in a non-volatile storage medium and a memory in the energy storage system.
Specifically, after determining the current state parameter of the energy storage battery, the present state parameter of the energy storage battery may be stored in a nonvolatile storage medium and an energy storage system memory (RAM) of the energy storage system by a micro control unit (Microcontroller Unit, abbreviated as MCU) in a storage device of the energy storage battery parameter in the energy storage system.
The nonvolatile storage medium in this embodiment is located inside a Real Time Clock (RTC).
It can be appreciated that the integrity of the state parameters of the energy storage battery can be effectively ensured by storing the current state of the energy storage battery in the nonvolatile storage medium and the content of the energy storage system.
It should be noted that, in the actual use process, in order to save space, the RTC chip is usually powered by the button battery, however, the button battery has a service time limit, so when the electric quantity of the button battery is exhausted, the user is not easy to perceive, and the data in the NVRAM area in the RTC chip is lost under the conditions that the user is unconscious and unknowable.
Therefore, in order to effectively avoid the loss of the state parameters of the energy storage battery stored in the NVRAM area in the RTC chip due to insufficient electric quantity of the power supply equipment, the invention can supply power to the RTC chip through the power supply system in the energy storage system.
The voltage value provided to the RTC chip may be adaptively set according to the voltage of the RTC chip when the RTC chip is operating normally, which is not particularly limited in the present invention. For example, it may be 3.3 volts (V).
Furthermore, the invention supplies power to the RCT chip through the energy storage system and simultaneously charges the chargeable capacitor, so that when the power supply system in the energy storage system is powered down, the chargeable capacitor can continuously supply power to the RTC chip, thereby ensuring that the state parameters of the energy storage battery stored in the NVRAM area in the RTC chip are not lost.
In this embodiment, when the charging operation is performed on the chargeable capacitor, the charging operation is performed according to the normal operating voltage of the chargeable capacitor, for example, may be 5V, which is not particularly limited in the present invention.
The chargeable capacitor in the present invention may be a faraday capacitor, which is not particularly limited in the present invention.
In a specific implementation, the power supply end of the real-time clock chip may be connected to one end of the chargeable capacitor, and the specific connection manner may be seen in fig. 2.
As shown in fig. 2, the rechargeable capacitor is illustrated by taking a faraday capacitor as an example, where the purpose of supplying power to the RTC chip can be achieved by connecting the positive electrode of the faraday capacitor to the positive pin 3 of the standby power supply of the RTC chip and connecting the negative electrode of the faraday capacitor to the negative pin 4 of the RTC chip.
In addition, the RTC chip includes the following pins, crystal oscillator input/output pins 1 and 2, an enable pin 5, a data transmission pin 6, a communication clock pin 7, and a main power supply positive pin 8.
The crystal oscillator input/output pins 1 and 2 are connected with a clock circuit to provide clock pulses for the RTC chip. In this embodiment, the clock circuit provides clock pulses to the RTC chip at 1s intervals.
And pins 5 and 6 of the RTC chip are respectively connected with the micro-control unit so as to realize the state parameter access operation of the energy storage battery according to the control of the micro-control unit.
The positive pin 8 of the main power supply is used for achieving the purpose that the energy storage system supplies power to the RTC chip.
Step 103, judging whether the time interval between the current time and the last time of storing the state parameters in the flash is smaller than a threshold value, if not, executing step 104, otherwise, executing step 105.
In this embodiment, the flash is a physical medium for storing data in the embedded device.
Specifically, in order to avoid the situation that the stored state parameters are damaged due to the limitation of the writing times of the flash memory medium, in this embodiment, after the current state parameters of the energy storage battery are stored in the nonvolatile storage medium and the memory, the storage device of the energy storage battery parameters in the energy storage system obtains time information of historical read-write operation of flash in the energy storage system from the storage unit, and obtains the time of one read-write operation closest to the current time.
And then, performing difference between the current time and the acquired latest read-write operation time, comparing the difference with a threshold value, and determining whether the difference is larger than the threshold value. If the difference value is not smaller than the threshold value, the condition that the determined current state parameter of the energy storage battery is stored in the flash of the energy storage system is met at the current moment, and otherwise, the condition is not met.
The threshold value can be adaptively set according to the characteristics of the flash read-write operation times, which is not particularly limited in the invention. For example, 600 seconds(s), 650s, etc.
And 104, storing the current state parameters into the flash.
Specifically, when the time interval between the current time and the time when the last flash performs the read-write operation is not smaller than the threshold value, the flash is indicated to be capable of writing in the current state parameter of the energy storage battery. The current state parameters of the energy storage battery can be stored in the flash for the MCU, so that triple backup of the state parameters of the energy storage battery is realized, the state parameter information of the energy storage battery is further ensured to be not easy to lose, and the accuracy of detecting the state safety of the energy storage battery is improved.
Step 105, redetermining the current state parameters of the energy storage battery.
Specifically, when the time interval between the current time and the time when the last flash performs the read-write operation is smaller than the threshold value, the flash is indicated to be unable to completely write the current state parameters of the energy storage battery. Therefore, the embodiment can end the storing operation of the currently acquired state parameter and acquire the state parameter of the energy storage battery again.
Furthermore, in order to facilitate the subsequent integrity check of the state parameter of the energy storage battery, the invention can also determine the check code corresponding to the state parameter when determining the current state parameter of the energy storage battery, and can jointly store the state parameter and the corresponding check code when executing the storage operation, thereby ensuring that when the state parameter of the energy storage battery is read subsequently, whether the read state parameter is complete and legal can be verified according to the stored check code.
Specifically, the current state parameters are stored in a nonvolatile storage medium in an energy storage system, and meanwhile, a first check code is written into the nonvolatile storage medium; writing a second check code into the memory of the energy storage system while storing the current state parameters into the memory of the energy storage system; and writing a third check code into the flash while storing the current state parameters into the flash.
In a specific implementation, the present embodiment may store the current state parameter, the first check code, the second check code, and the third check code according to a mapping relationship, which is not limited in this embodiment.
The first check code, the second check code, and the third check code may be, but are not limited to, cyclic redundancy check codes (Cyclic Redundancy Check, abbreviated as cyclic redundancy check codes), hamming codes, and the like, which are not particularly limited in the present invention.
According to the method for storing the parameters of the energy storage battery in the energy storage system, the current state parameters of the energy storage battery are firstly determined, the current state parameters of the energy storage battery are stored in a nonvolatile storage medium and a memory in the energy storage system, a user judges whether the time interval between the current moment and the last time of storing the state parameters into the flash is smaller than a threshold value or not, and if the time interval is not smaller than the threshold value, the current state parameters are stored into the flash. Therefore, when the state parameters of the energy storage battery are stored, the condition that the stored state parameters are damaged due to the limitation of the writing times of the flash memory medium is avoided, the integrity of the state parameters of the energy storage battery is effectively ensured, the accuracy and the reliability of the state detection of the energy storage battery are improved, and the user experience is improved.
According to the analysis, after the current state parameters of the energy storage battery are stored in the nonvolatile storage medium and the content of the energy storage system, whether the time interval between the current moment and the last time of storing the state parameters into the flash is smaller than a threshold value is judged, and if the time interval is not smaller than the threshold value, the current state parameters are stored into the flash. Furthermore, after the current state of the energy storage battery is stored in a nonvolatile storage medium, a memory and a flash of the energy storage system, the method can also read the stored state parameters of the energy storage battery and carry out integrity check on the read state parameters. The following describes in detail a method for reading parameters of an energy storage battery in the energy storage system according to the present invention with reference to fig. 3.
Fig. 3 is a flowchart of a method for reading parameters of an energy storage battery in an energy storage system according to an embodiment of the present invention.
As shown in fig. 3, the method for reading the parameters of the energy storage battery in the energy storage system according to the embodiment of the invention may include the following steps:
step 301, obtaining a reading request of the state parameter of the energy storage battery.
In the specific implementation, the micro control unit can send a read request to the nonvolatile storage medium, the memory of the energy storage system and the flash.
Step 302, reading a status parameter from a non-volatile storage medium according to a read request.
Step 303, checking the integrity of the status parameter read from the nonvolatile storage medium, if so, executing step 304, otherwise executing step 305.
Specifically, since the first check code is stored in the nonvolatile storage medium, when the state parameter of the energy storage battery is read in the nonvolatile storage medium, the corresponding state parameter and the corresponding first check code can be obtained.
In order to facilitate checking the integrity of the acquired state parameter, in this embodiment, when acquiring the state parameter, the reading device of the energy storage battery parameter may randomly generate a check code (fourth check code), so the present invention may match the generated check code with the acquired first check code to determine whether the read state parameter of the energy storage battery is lost or damaged.
If the fourth check code generated randomly is matched with the first check code, the state parameters of the energy storage battery are completely stored, and no loss or damage occurs; if the fourth check code generated randomly is not matched with the first check code, the state parameters of the energy storage battery are possibly lost or damaged.
And step 304, calculating parameters of the energy storage system according to the state parameters.
For example, if the read state parameter is the current of the energy storage battery, then an integration operation can be performed according to the obtained current parameter, so that the capacity information of the energy storage battery can be obtained.
Step 305 reads the state parameters from the memory of the energy storage system.
Specifically, since the memory of the energy storage system also stores the state parameters of the energy storage battery, when the fourth check code is determined to be not matched with the first check code, the state parameters of the energy storage battery can be obtained from the memory of the energy storage system to determine whether the state parameters of the energy storage battery are complete.
Step 306, after reading the status parameter from the memory of the energy storage system, checking the integrity of the status parameter read from the memory of the energy storage system, if so, executing step 307, otherwise, executing step 308.
Specifically, since the second check code is stored in the content of the energy storage system, when the state parameter of the energy storage battery is read in the content of the energy storage system, the corresponding state parameter and the corresponding second check code can be obtained.
In order to facilitate checking the integrity of the acquired state parameter, in this embodiment, when acquiring the state parameter, the reading device of the energy storage battery parameter may also randomly generate a check code (fifth check code), so that the present invention may determine whether the read state parameter of the energy storage battery is lost or damaged according to the generated check code and the acquired second check code.
If the randomly generated fifth check code is matched with the second check code, the state parameters of the energy storage battery are completely stored, and no loss or damage occurs; if the randomly generated fifth check code is not matched with the second check code, the state parameters of the energy storage battery are possibly lost or damaged.
And 307, calculating parameters of the energy storage system according to the state parameters.
Step 308, reading the status parameters from the flash.
Step 309, after reading the status parameters from the flash, checking the integrity of the status parameters read from the flash, if so, executing step 310, otherwise, executing step 311.
Specifically, since the state parameter of the energy storage battery and the corresponding third check code are also stored in the flash, when the state parameter of the energy storage battery is read from the flash according to the read request, the reading device of the state parameter of the energy storage battery also randomly generates a check code (sixth check code), and then matches the sixth check code with the third check code to determine whether the read state parameter of the energy storage battery is lost or damaged.
If the randomly generated sixth check code is matched with the third check code, the state parameters of the energy storage battery are completely stored, and no loss or damage occurs; if the randomly generated sixth check code is not matched with the third check code, the state parameters of the energy storage battery are possibly lost or damaged.
And step 310, calculating parameters of the energy storage system according to the state parameters.
Step 311, the default parameters of the energy storage system are read for calculation.
Specifically, when the randomly generated sixth check code is not matched with the third check code, it is indicated that the state parameters of the energy storage battery stored in the nonvolatile storage medium, the memory of the energy storage system and the flash are lost or damaged, and at the moment, the state parameters of the energy storage battery are calculated according to a preset default parameter mode.
The state parameters of the energy storage battery may be battery health, battery sub-health, battery abnormality, etc., which are not particularly limited in the present invention.
It can be understood that the state parameters of the energy storage battery are respectively stored in the nonvolatile storage medium, the memory of the energy storage system and the flash, so that triple backup of the state parameters of the energy storage battery is realized. When the state parameters of the energy storage battery are stored, the nonvolatile storage medium is used as a first choice, the memory of the energy storage system is used as a second choice, and the alternative is flash. When the integrity of the state parameters of the energy storage battery is verified, the integrity of the state parameters stored in the non-volatile storage and the memory of the energy storage system can be verified, if the read data is lost or damaged, the stored state parameters are read from the alternative flash, the integrity of the state parameters is verified, and if the state parameters stored in the three are lost or damaged, the state of the energy storage battery is calculated according to the default state parameter mode in the energy storage system, so that the accuracy and the reliability of the detection of the energy storage battery are improved.
In the method for reading the parameters of the energy storage battery in the energy storage system provided by the embodiment, after the reading instruction, the state parameters are read from the nonvolatile storage medium, whether the read state parameters are complete or not is checked, if yes, the parameter calculation of the energy storage system is performed according to the state parameters, otherwise, the state parameters are read from the content of the energy storage system, if complete, the parameter calculation of the energy storage system is performed according to the state parameters, otherwise, the state parameters are read from the flash, if complete, the parameter calculation of the energy storage system is performed according to the state parameters, and if not, the default parameter calculation of the energy storage system is performed.
