  • Publication number: 20240363858
    Abstract: The present application provides a secondary battery, a battery module, a battery pack, and an electrical device. The secondary battery includes a positive electrode plate, a negative electrode plate, and a separator disposed between the positive electrode plate and the negative electrode plate, in which the positive electrode plate comprises a positive electrode coating containing a positive electrode active material comprising a lithium iron phosphate material and a conjugated carbonyl compound. In a discharge process of the secondary battery, in addition to a discharge plateau of the lithium iron phosphate material, a discharge curve further includes a relatively low discharge plateau provided by the conjugated carbonyl compound.

  • Publication number: 20240172401
    Abstract: A chassis for an edge device includes a cabinet and a heat exchange component. The heat exchange component is disposed in a space enclosed by the cabinet. The space in the cabinet is divided into a first space and a second space for placement an electronic device. The heat exchange component performs heat transfer between the first space and the second space. A first air inlet and a first air outlet are disposed in the first space, and an airflow entering from the first air inlet flows through a first surface of the heat exchange component and exits from the first air outlet.

  • Patent number: 11308062
    Abstract: An index update method, including: receiving an index update request, where the index update request is used to instruct to create or delete a target index that is associated with a field in a logic table of a tenant; updating metadata information of the logic table in a database in response to the index update request; notifying a coordination service, where the coordination service is used to notify a second data access node to perform a local synchronization update; and after all second data access nodes finish local synchronization updates, performing a data asynchronization update. After the metadata information is updated in the database, an index is updated in two steps. In a first step, a local synchronization update is performed. In a second step, after all data access nodes finish local synchronization updates, a data asynchronization update is performed.

  • Publication number: 20200019552
    Abstract: A query optimization method performed by a data access node includes: receiving a query request that is used to query tenant data; searching for a cached optimal query plan for the query request; if the optimal query plan is found, using the optimal query plan as a target query plan; or if no optimal query plan is found, generating a target query plan corresponding to the query request; and submitting the target query plan to a database, where the target query plan is used by the database to query the tenant data. Logical access (query request) is converted into a query plan (physical data access) by the data access node rather than a database node. In addition, the optimal query plan is used for query, so as to reduce a query cost as much as possible, and improve query performance.
