Abstract: A data prefetching method and apparatus, and related storage device are provided. Data samples are collected. An AI chip trains the data samples to obtain a prefetching model. The AI chip then sends the prefetching model to a processor. The processor reads to-be-read data into a cache based on the prefetching model to reduce the computing burden of the processor.

Abstract: This disclosure provides an access request processing method, a storage device, and a storage system. In embodiments of this disclosure, a first storage device receives an artificial intelligence (AI) model from a second storage device, wherein the AI model is obtained by the second storage device through training based on historical input output (IO) requests in historical running processes. The first storage device obtains a prediction result of the AI model based on an access request received by the first storage device.

Abstract: A charging method and apparatus are provided. In a process of performing constant voltage charging on a battery at a charging voltage that is greater than an end-of-precharge voltage and less than a maximum charging voltage, the charging apparatus determines a current relaxation time and controls a charging current and a charging voltage based on the current relaxation time, to adaptively charge the battery. This better adapts to a change inside the battery in the charging process, effectively improves safety and reliability of the battery in the charging process, enhances cycle performance of the battery, and prolongs battery life.

Abstract: This application provides an example load threshold determining method and apparatus. The method includes obtaining a plurality of preselected load thresholds of a cell. The method also includes obtaining an evaluation value corresponding to each preselected load threshold in a first periodicity, where each evaluation value is used to evaluate key performance indicator (KPI) information and energy saving information of the cell. The method further includes determining a target load threshold of the cell in a second periodicity based on all evaluation values, where the target load threshold is a load threshold in the plurality of preselected load thresholds, and where the second periodicity is a next periodicity of the first periodicity.
