Abstract

The embodiment of the invention discloses a power supply method, device and system for storage batteries, wherein the power supply method comprises the step as follows: the power supply state of a storage battery circularly used in a system is detected, wherein the system supplies power to a load through the storage battery circularly used firstly; when the voltage of the storage battery circularly used is reduced to a voltage threshold, a standby storage battery is started to supply power to the load. The embodiment can realize mixed application between different storage batteries.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a battery power supply method, device and system. Background technique [0002] With the rapid development of mobile communications, there are more and more unattended outdoor base stations. Since most outdoor base stations are generally located in remote areas, the grid environment is poor or there is no utility power. Most non-mains communication base stations on the existing network use dual-fuel generators to alternate power supply. With the introduction of new low-cost and low-fuel consumption power supply solutions, a large number of communication base stations need to be optimized. [0003] In the actual site reconstruction process, due to the different internal resistances of new and old batteries or different types of batteries, these batteries cannot be mixed. The existing general treatment method is: directly discard the original lead-acid batteries ...
