Abstract

In response to the new requirements for backup power supply in the 2023 national standard draft for comments of Combustible Gas Alarm Controller, a Battery Management System (BMS) design scheme for combustible gas alarm controllers is proposed. The core of the scheme lies in replacing the lead-acid battery in the backup power supply system with a lithium iron phosphate battery, and performing data acquisition and control functions through a BMS chip to achieve real-time monitoring and safety protection of the backup power supply's battery capacity and voltage. By designing a reasonable main and backup power supply switching scheme, the output control of the backup power supply is achieved. After verification in the established test environment, the design complies with the standards of the draft for comments and can fully meet the requirements for complex on-site work.

Keywords
