This application provides a method for detecting a battery state of health. In the method, for a battery that does not supply power to a load within a time period, a detected unit is determined; an open-circuit voltage and a temperature of the detected unit are collected; a battery state of charge value and a loss capacity of the detected unit are obtained by means of calculation; and a battery state of health value of the detected unit is obtained by means of calculation according to a ratio of the loss capacity of the detected unit to an original capacity. This application further provides an apparatus for detecting a battery state of health. By means of technical solutions provided in this application, a deterioration degree of battery performance can be accurately monitored, and impact on a service is avoided.

Apparatus and method for detecting battery state of health

A method for detecting a battery state of health includes a current and a voltage are measured twice in a period of time; corresponding model algorithms are selected according to the measured current values; corresponding battery open circuit voltage values and battery state of charge values at a start time and an end time of the period are obtained based on the model algorithms; a battery capacity difference that indicates a present battery retention capacity and a battery capacity difference that indicates a future battery retention capacity are calculated; and a battery state of health value is calculated when impact of a measured battery temperature value is considered.

A method for implementing a configurable on-chip interconnection system. The method comprises: in an interconnection system, master devices set bit widths of bus identifiers of the master devices, wherein the bit widths of the bus identifiers of the master devices are the same (); and in a memory access process, the mater devices interact, by means of interconnection matrices only, with slave devices according to the bus identifiers (). Also provided are a system and apparatus for implementing the method, and a storage medium.
