Abstract
Compared with other types of batteries, the lithium-ion battery have many advantages, ing an indispensable part of our daily lives. I believe that in the process of using lithium-ion battery, we often consider the question of how much power is left, but they can not find a good power detection method. for the requirements, we design a lithium-ion battery detection system based on MCU, the detection system can meet the demand for lithium-ion battery detection in our daily lives , in order to fully grasp the charge status of the lithium-ion battery.
This paper describes the research and design of lithium-ion battery detection system based on MCU The system consists of a Analog acquisition module, battery detection module, MCU module and LED drive power display modules. the article describes the characteristics of the lithium-ion battery, the battery detection principle, structure and performance of the system,, focusing on the system hardware and software design.
Taking into account plexity of the detection system, accuracy, reliability, and other aspects, the article describes the design can meet the requirements of our lithium-ion battery detection.
