The embodiments of the present application are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are intended to be illustrative, and are not to be construed as limiting.

The storage method of the energy storage battery parameters in the energy storage system provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings.

1 is a flow chart of a method for storing energy storage battery parameters in an energy storage system according to an embodiment of the present application.

As shown in FIG. 1 , the method for storing energy storage battery parameters in the energy storage system of the embodiment of the present application may include the following steps:

Step 101: Determine a current state parameter of the energy storage battery.

The storage method of the energy storage battery parameter in the energy storage system provided by some embodiments of the present application may be performed by the storage device of the energy storage battery parameter in the energy storage system provided by the application, and the device may be configured in the electronic device to implement Control or manage the state parameters of the energy storage battery.

The state parameters of the energy storage battery in this embodiment may include, but are not limited to, a state of charge (SOC), voltage, current, internal resistance, temperature, and the like.

According to other embodiments of the present application, the current state parameters of the energy storage battery can be obtained by using a voltage sensor, a current sensor, a temperature sensor, or the like, which is not specifically limited in this application.

Step 102: Store the current state parameter into a non-volatile storage medium in the energy storage system.

According to other embodiments of the present application, after determining the current state parameter of the energy storage battery, in order to be able to completely and reliably store the current state parameter of the energy storage battery, the present embodiment passes the storage device of the energy storage battery parameter in the energy storage system. The Microcontroller Unit (MCU for short) stores the current state parameters of the energy storage battery into the non-volatile storage medium.

The non-volatile storage medium in this embodiment is located inside a Real Time Clock (RTC).

It can be understood that by storing the current state parameters of the energy storage battery in the non-volatile storage medium, the integrity of the energy storage battery state parameter can be effectively ensured.

It should be noted that, in actual use, in order to save space, the RTC chip is usually powered by a button battery. However, the button battery has a use time limit, so when the button battery is exhausted, the user is not easy to detect and will be unconscious in the user. Uninformed, causing data loss in the NVRAM area of the RTC chip.

Therefore, in order to effectively avoid the loss of state parameters of the energy storage battery stored in the NVRAM area of the RTC chip due to insufficient power supply, the present application may first supply power to the RTC chip through the power supply system in the energy storage system.

The voltage value provided to the RTC chip can be adaptively set according to the voltage of the RTC chip during normal operation, which is not specifically limited in this application. For example, it can be 3.3 volts (V).

According to other embodiments of the present application, the present application further charges the rechargeable capacitor while the power storage system supplies power to the RCT chip, so that when the power supply system in the energy storage system is powered down, the capacitor can continue to be charged. The RTC chip is powered to ensure that the state parameters of the energy storage battery stored in the NVRAM area of the RTC chip are not lost.

In this embodiment, when the charging operation is performed on the rechargeable capacitor, the charging operation is performed according to the normal working voltage of the rechargeable capacitor, for example, 5V, which is not specifically limited in the present application.

The chargeable capacitor in the present application may be a farad capacitor, which is not specifically limited in this application.

According to other embodiments of the present application, the power supply end of the real-time clock chip can be connected to one end of the rechargeable capacitor. For the specific connection manner, refer to FIG. 2 .

As shown in FIG. 2, the chargeable capacitor is described by taking a farad capacitor as an example. The positive electrode of the farad capacitor is connected to the positive power pin 3 of the RTC chip, and the negative electrode of the farad capacitor and the negative electrode of the RTC chip are shown. The connection of the foot 4 can realize the purpose of supplying power to the RTC chip.

In addition, the RTC chip further includes the following pins, crystal input/

output pins

1 and 2, enable pin 5, data transfer pin 6, communication clock pin 7, and main power supply positive pin 8.

Among them, the crystal input/

output pins

1 and 2 are connected to the clock circuit to provide clock pulses for the RTC chip. In this embodiment, the clock circuit supplies clock pulses at intervals of 1 s to the RTC chip.

The pin 5 and the pin 6 of the RTC chip are respectively connected to the micro control unit to implement the state parameter access operation of the energy storage battery according to the control of the micro control unit.

The main power supply positive pin 8 is used for the purpose of powering the energy storage system to the RTC chip.

Step 103: Determine whether the time interval between the current time and the last time the state parameter is stored in the flash is less than the threshold. If the result of the determination is not less than the threshold, step 104 is performed, otherwise step 105 is performed.

In this embodiment, the flash is a physical medium for storing data for the embedded device.

According to other embodiments of the present application, in order to avoid a situation in which the stored state parameters are damaged due to the limitation of the number of writes of the flash media, the present embodiment stores the current state parameters of the energy storage battery to the nonvolatile storage. After the medium, the storage device of the energy storage battery parameter in the energy storage system acquires the time information of the historical read and write operation of the flash in the energy storage system from the storage unit, and acquires the time of the first read and write operation from the current time.

Then, the current time is compared with the acquired last read and write operation time to obtain a time interval, and the time interval is compared with the threshold, and it is determined whether the time interval is greater than a threshold. If the time interval is not less than the threshold, it indicates that the current time meets the condition that the current state parameter of the determined energy storage battery is stored in the flash in the energy storage system, otherwise the condition is not satisfied.

The threshold value can be adaptively set according to the characteristics of the number of read and write operations of the flash media, which is not specifically limited in this application. For example, it can be 600 seconds (s), 650 seconds, and so on.

In step 104, the current state parameter is stored in the flash.

According to some embodiments of the present application, when determining that the time interval between the current time and the time of the last flash read/write operation is not less than the threshold, the current embodiment may directly store the current state parameter of the energy storage battery in the flash through the MCU. In order to achieve double backup of the important parameters in the state parameters of the energy storage battery, the accuracy is higher when the important state parameters of the energy storage battery are subsequently verified.

In step 105, the current state parameter of the energy storage battery is re-determined.

According to other embodiments of the present application, when it is determined that the time interval between the current time and the time when the most recent flash is read or written is less than the threshold, it indicates that the flash cannot be completely written into the current state parameter of the energy storage battery. Therefore, in this embodiment, the storage operation of the currently acquired state parameter may be ended, and the state parameter of the energy storage battery may be re-acquired.

According to other embodiments of the present application, in order to facilitate the subsequent integrity check of the state parameters of the energy storage battery, the present application may also determine a check code corresponding to the state parameter when determining the current state parameter of the energy storage battery, and When the storage operation is performed, the state parameter and the corresponding check code may be stored together, so that when the state parameter of the energy storage battery is subsequently read, the read state parameter can be verified according to the stored check code. .

According to further embodiments of the present application, the first check code is written into the non-volatile storage medium while the current state parameter is stored in the non-volatile storage medium in the energy storage system; While the status parameter is stored in the flash, the second check code is written into the flash.

According to other embodiments of the present application, the current state parameter, the first check code, the second check code, and the second check code may be stored according to the mapping relationship, which is not specifically limited in this embodiment. .

The first check code and the second check code may be, but are not limited to, a Cyclic Redundancy Check (Cyclic Redundancy Check), a Hamming code, etc., and the present application does not Specifically limited.

The above analysis shows that after storing the current state parameter of the energy storage battery in the non-volatile storage medium of the energy storage system, it is further determined whether the time interval between the current time and the most recent storage of the state parameter in the flash is less than a threshold. If the result of the determination is not less than the threshold, the current state parameter is stored in the flash. According to still other embodiments of the present application, after storing the current state of the energy storage battery to the non-volatile storage medium of the energy storage system, the flash, the stored energy storage battery state parameter may also be read in the present application, The integrity check is performed on the read status parameters. The method for reading the parameters of the energy storage battery in the energy storage system of the present application will be described in detail below with reference to FIG.

3 is a flow chart of a method of reading energy storage battery parameters in an energy storage system according to an embodiment of the present application.

As shown in FIG. 3, the method for reading energy storage battery parameters in the energy storage system of the embodiment of the present application may include the following steps:

Step 301: Acquire an energy storage battery status parameter read request.

According to further embodiments of the present application, the read request may be sent to the non-volatile storage medium, the memory of the energy storage system, and the flash by the micro control unit.

Step 302: Read status parameters from the non-volatile storage medium according to the read request.

In step 303, the integrity of the status parameter read from the non-volatile storage medium is verified. If yes, step 304 is performed; otherwise, step 305 is performed.

According to still other embodiments of the present application, since the first check code is stored in the non-volatile storage medium, when the state parameter of the energy storage battery is read in the non-volatile storage medium, not only the corresponding state can be acquired. The parameter can also obtain the corresponding first check code.

In order to facilitate the verification of the acquired state parameter integrity, in the embodiment, when the state parameter is acquired, the reading device of the energy storage battery parameter randomly generates a check code (third check code), whereby the application can be generated according to the present invention. The check code is matched with the obtained first check code to determine whether the state parameter of the stored energy storage battery is lost or damaged.

Wherein, if the randomly generated third check code matches the first check code, it indicates that the state parameter of the energy storage battery is completely preserved, and no loss or damage occurs; if the randomly generated third check code and the first check code are generated If the codes do not match, the status parameters of the energy storage battery may be lost or damaged.

Step 304: Perform parameter calculation of the energy storage system according to the state parameter.

For example, if the read state parameter is the current of the energy storage battery, the capacity information of the energy storage battery can be obtained by performing an integral operation according to the obtained current parameter.

In step 305, the status parameter is read from the flash.

According to still other embodiments of the present application, since the flash also stores the state parameter of the energy storage battery, when it is determined that the third check code does not match the first check code, the state parameter of the energy storage battery may be obtained from the flash. To determine if the state parameters of the energy storage battery are complete.

Step 306: After reading the state parameter from the flash, verify the integrity of the state parameter read from the flash. If yes, perform step 307, otherwise perform step 308.

According to still another embodiment of the present application, since the state parameter of the energy storage battery and the corresponding second 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 energy storage is performed. The reading device of the battery parameter also randomly generates a check code (fourth check code), and then matches the fourth check code with the second check code to determine whether the state parameter of the stored energy storage battery is Lost or damaged.

Wherein, if the randomly generated fourth check code matches the second check code, it indicates that the state parameter of the energy storage battery is completely preserved, and no loss or damage occurs; if the randomly generated fourth check code and the second check are generated If the codes do not match, the status parameters of the energy storage battery may be lost or damaged.

Step 307: Perform parameter calculation of the energy storage system according to the state parameter.

In step 308, the default parameters of the energy storage system are read for calculation.

According to some embodiments of the present application, when the randomly generated fourth check code does not match the second check, it indicates that the non-volatile storage medium and the energy storage battery state parameters stored in the flash are lost or damaged. Then, the state parameter of the energy storage battery is calculated according to the preset default parameters.

The status parameter of the energy storage battery may be: battery health, battery sub-health, battery abnormality, etc., which is not specifically limited in this application.

It can be understood that the present application implements double backup of the energy storage battery state parameters by storing the state parameters of the energy storage battery in the non-volatile storage medium and the flash respectively. Among them, when storing the state parameters of the energy storage battery, the non-volatile storage medium is preferred, and the flash is the second selection. Therefore, when the integrity parameter of the state parameter of the energy storage battery is checked, the integrity parameter of the state parameter stored in the non-volatile storage medium may be first checked, and if the read data is found to be lost or damaged, the candidate is selected. The stored state parameter is read in the flash, and the state parameter integrity is verified. If the state parameter stored in the above two states is missing or damaged, the energy storage battery is used according to the default state parameter in the energy storage system. The state is calculated to improve the accuracy and reliability of the energy storage battery detection.

In the method for reading energy storage battery parameters in the energy storage system provided by the embodiment of the present application, after reading the instruction, the state parameter is read from the non-volatile storage medium, and the read state parameter is verified to be complete. If it is complete, the parameter calculation of the energy storage system is performed according to the state parameter. Otherwise, the state parameter is read from the flash, and the read state parameter is verified to be complete. If it is complete, the parameter calculation of the energy storage system is performed according to the state parameter. Otherwise, the default parameters of the energy storage system are read for calculation. Therefore, when the integrity check of the stored energy storage battery state parameter is performed, the verification operation can be implemented according to the check code corresponding to the state parameter of the energy storage battery, thereby improving the state detection of the energy storage battery. Accuracy and reliability meet the needs of the user and further enhance the user experience.
