Abstract

A battery pack capacity detection system based on combined neural network is characterized by being composed of a battery pack capacity detection training system and a battery pack capacity detection working system. The combined neural network in the battery pack capacity detection working system is composed of one BP network detection unit and three ELM network detection units. Each neural network detection unit is obtained by the battery pack capacity detection training system through training with sample data. They are respectively suitable for capacity detection in different ranges. When applied, they can be appropriately combined according to the intermediate results, which can learn from each other and optimize the final detection results: when performing capacity detection on a battery pack to be tested, first use the BP network detection unit to perform the detection. In the primary detection, the range of the capacity of the battery pack to be tested is determined; then the ELM network detection unit suitable for the range is selected for the secondary detection, so that more accurate detection results can be obtained.

Description

technical field [0001] The invention belongs to the technical field of battery capacity detection, and relates to a battery pack capacity detection system that uses a combined neural network. Background technique [0002] The battery pack in the communication radio station is one of the key components to ensure the normal operation of the communication equipment. The performance and remaining capacity of the battery pack directly affect the performance of the radio station, which is related to the normal operation of the equipment and the smooth communication. [0003] The following problems exist in the use of communication station battery packs: maintain the battery packs with a lot of remaining charge or have not reached the maintenance cycle; continue to use the battery packs with poor charge performance or failure. The above problems will affect the cycle life of the battery pack and the normal use of the equipment. The existing technical means to detect the state of c...
