POWER MANAGEMENT SYSTEM

摘要

A system for determining and for allowing remote monitoring of the full charge
back-up
time that can be provided by a plurality of batteries, at all time, in a given
application
(such as a Tele communication Outside Plant) requiring a given current load
from the
power grid, which system; comprising:
- a plurality of batteries that can deliver information such as their full
charge
capacity and ambient temperature at all time;
- a device that can measure the application load (such as current in Amperes);
and
- an interface device (BID) that couples the information from the load device
and
from the batteries (full charge capacity) to determine the back-up time
available
in the given application and to have this information available for remote
monitoring.
