Simple Circuit Monitors Health of вЂ“48V Telecom Lead-Acid
Battery Backup Systems
Jon Munson Telecommunications infrastructure has always been powered by voltages that
are negative with respect to ground to minimize corrosion in buried cable.
Telcos typically use вЂ“48V power, with backup power supplied by large battery
arrays to carry the system through utility outages. These power backup systems
traditionally comprise four 12V lead-acid batteries in series, though newer
lithium cell technology promises to make inroads as systems are updated.
Every battery backup system must be
continually monitored for the charge
state and health of the batteries. In fact,
although stacking batteries is easy, it
can be difficult to build a monitoring
system that can measure and digitize
both the condition of individual cells, and monitor the high voltage potential
of the combined cells. Enter the LTC6803
multicell battery stack monitor.
The LTC6803 is designed to measure and
digitize individual cell potentials in large
lithium cell stacks with total potentials 100О© Figure 1. Isolated lead-acid
