Battery Manager Expansion Module
Smart-charging and remote battery management for stationary UPS batteries.
Includes : Installation guide
The Schneider Electric Battery Manager provides automated monitoring and management of stationary battery backup systems of between 100 VDC and 560 VDC per string. The Battery Manager is capable of managing battery systems of various configurations and capacities, provided that all battery systems attached to one Battery Manager system are identical.
The battery systems can be comprised of nominal 2V, 4V, 8V, or 12V lead-acid batteries, or 1.2V or 2.4V nickel-cadmium batteries. The Battery Manager is designed to be agnostic to charger and load considerations, provided that the voltage source is of a constant voltage design.
The Battery Manager supports up to two strings of batteries. Systems managing one string of batteries can support up to 244 lead-acid cells, or up to 375 nickel-cadmium cells. Systems with two strings can manage strings of up to 244 lead-acid cells per string, or up to 256 nickel-cadmium cells per string.
The Battery Manager is controlled through the Network Management Card (NMC) within the Networked Unit.
The Battery Manager can:
Optimize the charge state of individual batteries within a string; lower voltage cells are automatically boost-charged to bring the voltages up to approximately the string average level. - Managing batteries on an individual basis extends the useful life of otherwise undercharged or overcharged batteries and achieves full capacity of otherwise undercharged batteries.
Monitor and manage batteries connected to one Networked Unit (AP9922) and up to seven expansion units (AP9922S); a maximum of eight units can be connected.
Connect each unit to as many as 64 individual batteries
Manage groups of batteries through a serial connection or IP address. The first unit, or Networked Unit, is the only unit of the group equipped with networking capabilities.
Identify weak or defective batteries needing replacement.
Issue alerts if various system conditions reach alarm status and require attention.
