The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a structure of a battery storage system based on the present application will be explained:
the management method of the battery storage system provided by the embodiment of the application is suitable for dividing and managing the storage space in the battery storage system. The data storage method of the battery storage system is suitable for storing data to be stored in the battery storage system. As shown in fig. 1, a schematic structural diagram of a battery storage system based on an embodiment of the present application mainly includes a memory, a management device of the battery storage system, and a data storage device of the battery storage system. Specifically, the management device allocates a storage space of the memory for the data to be stored of each data type according to the size of the data to be stored of each data type and the attribute information of the battery storage system, and correspondingly, the data storage device is used for storing the data to be stored to a target storage area corresponding to the data storage device.
The embodiment of the application provides a management method of a battery storage system, which is used for dividing and managing a storage space in the battery storage system. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a notebook computer, a tablet computer, and other electronic devices that can be used for managing a battery storage system.
As shown in fig. 2, a schematic flowchart of a management method of a battery storage system according to an embodiment of the present application is provided, where the method includes:
step 201, acquiring attribute information of the battery storage system and data size of target storage data.
The attribute information of the battery storage system may be specifically determined according to an actual situation of the battery storage system in actual application.
Specifically, in one embodiment, the attribute information of the battery storage system may include a service life of the battery storage system and a maximum number of times of erasing of the battery storage system.
Step 202, determining the average erasing data amount according to the data size and the attribute information of the target storage data.
It should be noted that the average erasure data amount is an amount of data erased every time data erasure is performed, and is in units of bytes as the data size.
Specifically, in an embodiment, a data storage period may be determined according to a preset minimum data variation and a data variation rate corresponding to the target storage data; determining the average erasing number according to the data storage period, the service life of the battery storage system and the maximum erasing number of the battery storage system; and determining the average erasing data quantity according to the average erasing quantity and the data size of the target storage data.
It should be noted that the data storage cycle refers to the time consumed for storing one target storage data, and the average number of erasures refers to the total number of target storage data erased for each data erasure. The minimum data variation amount may be specifically set according to an actual storage requirement of the target storage data, and the smaller the minimum data variation amount is, the higher the data resolution of the target storage data is, and the larger the storage space occupied by a single target storage data is. The data change rate is determined according to the data type of the target storage data, and particularly refers to the change condition of the minimum change quantity of the data in unit time.
Specifically, in one embodiment, the data storage period may be calculated according to the following formula:
t＝a/a’
wherein t represents a data storage period, the unit is second, a represents the minimum variation of data, and a' represents the data variation rate corresponding to the target storage data.
Further, in one embodiment, the average number of erasures may be calculated according to the following formula:
Figure BDA0002801125730000071
wherein n represents the average erasing number, Y represents the service life of the battery storage system, t represents the data storage period, and E represents the maximum erasing number of the battery storage system.
Further, in one embodiment, the average amount of erasure data can be calculated according to the following formula:
M＝n*b
where M denotes the average erasure data amount, and b denotes the data size of the target storage data.
For example, when the target storage data is the accumulated discharge electric quantity Acc _ DSG _ kWh, acquiring the attribute information of the battery storage system includes: the rated voltage U of the battery storage system is 300V, the maximum battery discharge current is 100A, the service life of the battery storage system is 8 years, the maximum number of times of erasing the battery storage system is 100000, the data size b of the data Acc _ DSG _ kWh is 4 bytes, and the minimum data variation a is 0.1 kWh.
(1) From the data minimum variation a of the data Acc _ DSG _ kWh of 0.1kWh, the battery rated voltage U of 300V and the maximum discharge current I of 100A, the time t (data storage period) required for each 0.1kWh variation is calculated:
t ═ a/a ═ a/(U ═ I) ═ 12s, 1 Acc _ DSG _ kWh data is stored every 12s at the fastest;
(2) according to the fact that the service life of the battery storage system is 8 years, 1 piece of Acc _ DSG _ kWh data is stored every 12s at the fastest speed in combination with (1), and according to the maximum erasing frequency E of the battery storage system being 100000, the average erasing number is calculated:
Figure BDA0002801125730000081
(3) calculating an average erasing data amount M corresponding to the average erasing number according to the data size b of the single data Acc _ DSG _ kWh being 4 bytes by combining (2):
M＝n*b＝211*4＝844
it is to be explained that the target stored data may also be the battery charge-discharge ampere hours, capacity, SOC, SOH, and the like. The data change rate a' corresponding to the accumulated discharge electric quantity Acc _ DSG _ kWh is U/I, a calculation mode of the data change rate is specifically determined according to a data type corresponding to the target storage data, and a specific calculation mode of the data change rate corresponding to the target storage data of each data type may refer to the prior art, which is not limited in the embodiment of the present application.
Step 203, allocating a storage space for the target storage data according to the average erasing data amount to obtain a target storage area.
It should be explained that the determination of the average erasing data amount combines with various attribute information of the battery storage system and the data size of the target storage data, and allocates a storage space with the average erasing data amount size for the target storage data, so that the data amount of data erasing each time is basically the same as the average erasing data amount, thereby reducing the data erasing times of the memory in the battery storage system.
According to the management method of the battery storage system, the attribute information of the battery storage system and the data size of target storage data are acquired; determining the average erasing data quantity according to the data size and the attribute information of the target storage data; and according to the average erasing data quantity, allocating a storage space for the target storage data to obtain a target storage area. According to the management method of the battery storage system, the storage space can be reasonably distributed for the data to be stored of each data type according to the attribute information of the battery storage system and the data size of the data to be stored of each data type, the data erasing times of the memory in the battery storage system are reduced, the service life of the memory is ensured, and a foundation is laid for improving the data storage efficiency.
The embodiment of the application provides a data storage method of a battery storage system, which is used for storing data to be stored in the battery storage system. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a notebook computer, a tablet computer, and other electronic devices that can be used for data storage.
As shown in fig. 3, a schematic flow chart of a data storage method of a battery storage system according to an embodiment of the present application is shown, where the method includes:
step 301, obtaining data to be stored.
It should be explained that, while the data to be stored is acquired, the data type corresponding to the data to be stored may also be acquired, where the data type includes the accumulated discharge electric quantity Acc _ DSG _ kWh, and the like.
Step 302, storing the data to be stored into the target storage area with the same data type as the data to be stored.
The target storage area is obtained by using the management method of the battery storage system provided by the above embodiment.
It should be explained that, based on the management method of the battery storage system provided in the foregoing embodiment, the storage space of the memory of the battery storage system may be divided according to the data type of each target storage data, so as to obtain the target storage area corresponding to the target storage data of each data type.
Specifically, in an embodiment, before storing the data to be stored in the target storage area with the same data type as the data to be stored, it may be determined whether the total amount of data stored in the target storage area reaches the average erasing data amount; and when the total amount of the data stored in the target storage area is determined to reach the average erasing data amount, erasing the data in the target storage area.
Specifically, before storing the data to be stored in the corresponding target storage area, it is necessary to determine whether the total amount of data stored in the current target storage area reaches the average erasing data amount. Because the size of the target storage area is the same as the average erasing data amount, if it is determined that the total amount of data stored in the target storage area reaches the average erasing data amount, it may be determined that the remaining storage space of the current target storage area is not enough to store the currently obtained data to be stored, and therefore, the data in the target storage area needs to be erased.
Similarly, in an embodiment, before storing the data to be stored in the target storage area with the same data type as the data to be stored, it may also be determined whether the total number of the data stored in the target storage area reaches the average number of erasures; and when the total number of the data stored in the target storage area is determined to reach the average erasing number, erasing the data in the target storage area.
Specifically, the total number of stored data may be accumulated in a counting manner, and when the total number of stored data reaches the average number of erasures, the data in the storage area may be erased.
According to the data storage method of the battery storage system, data to be stored are obtained; and storing the data to be stored into a target storage area with the same data type as the data to be stored, wherein the target storage area is obtained by adopting the management method of the battery storage system. According to the data storage method of the battery storage system, the data to be stored is stored to the corresponding target storage area according to the data type of the data to be stored, and the data storage efficiency is improved.
