[0003] At present, in the routine monitoring process, data storage is generally carried out using relational databases, and data is stored in tables in relational databases. According to the above recording method, for data storage of energy storage batteries, one table is needed per day, so a single There are also 140 million table data, which is very large and takes up a lot of storage space; since the single table data of a normal relational database reaches 10 million, it is already very large. Therefore, for such a large amount of data storage, it needs to be further divided table; and repeated table division brings a lot of inconvenience to code implementation, and it is also difficult to maintain and upgrade

Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0045] The invention provides a method for storing data of an energy storage cell to save the storage space of the data of the energy storage cell.
[0046] The method for storing the data of the energy storage cell is applied to the collection and storage system of the data of the energy storage cell, such as figure 1 As shown, the collection and storage system is connected with each battery management system of the monitored energy storage battery (ie figure 1 The BMS in the BATTERYMANAG...

The energy storage cell data storage method, query method and collection and storage system provided by the present invention generate a new time information block on the time chain of the information family of each battery management system when the data storage time is reached; The battery information block of the corresponding battery is generated on each cell chain of the information family of the battery management system, and together with the new time information block in the corresponding information family, a new time chain of the corresponding information family is formed; so that each information The family becomes a circular double-chain structure starting from its origin, which is used for data storage, and its storage structure is compact and occupies a small space.
Description
technical field [0001] The invention relates to the technical field of data storage, in particular to a storage method, a query method and a collection and storage system for data of an energy storage cell. Background technique [0002] Due to the large number of cells in the energy storage battery, the amount of data that needs to be stored is relatively large. For example, a 1MWH energy storage battery has about 5,000 cells, and the real-time data of each cell includes voltage, temperature, etc. For a 10MWH energy storage battery, if data is recorded once a minute, there will be at least 100,000 records each time, the total number of records in a day is 140 million, and the total number of records in a month is 4.2 billion , this data is very large. [0003] At present, in the routine monitoring process, data storage is generally carried out using relational databases, and data is stored in tables in relational databases. According to the above recording method, for data ...
