Product Introduction
2.1
– Overview
APL-LFP lithium ion battery is a battery pack with advanced LiFePO4 technology and intelligent
integrated BMS, which has the advantages of long cycle life, light weight, small size, safety and
environmental protection. APL-LFP lithium ion batteries can be used in a variety of indoor and
outdoor applications.
2.2
– Working Principle
The communication standby power supply consists of several lithium iron phosphate battery
units in series with the dedicated high performance and high reliability battery management
system (BMS).The +/- output terminal of the battery is connected to the +/- terminal of the
rectifier. When the mains supply is normal, the telecommunication equipment is supplied by
mains rectified power, and the battery pack is charged by rectified power. When the mains
power is interrupted, the backup power supply will be supplied to the telecommunication
equipment without delay to ensure that the power supply of the telecommunication equipment
is not interrupted until the mains power supply is restored or BMS automatically starts to protect
the power failure due to over-discharge protection.
