24VDC Li Expander Pak 1300 Operator Manual

PRINCIPLES OF OPERATION – THE EXPANDER PAK

The Expander Pak is designed as a modular, scalable energy storage module (ESM) for service in
any stand-alone power platform. Insertion of an Expander Pak into a circuit will allow the operator to
“expand” the architecture and improve the operating the efficiency of the entire network.

Expander Paks serve as the foundation for all hybrid power systems, allowing the use of renewables
and traditional power sources, simultaneously, in the same System.

The 24VDC Expander Pak 1300

:

• 54 Ah (1.3 kWh) of energy storage capacity
• LiFePO

4

cell chemistry

•  High energy density—twice that of lead-acid (double the energy for its weight)
•  High cycle life > 3000 cycles (@80% depth of discharge)
•  Plug & Play connection
•  Rapid and deep discharges (can go to near 0% without hurting the cells)
•  Rapid recharges
•  Internal circuit protections
•  Integrated vertical stacking
•  19-inch rack compatible
•  One-person lift
•  Inert and nonhazardous when 100% discharged
•  Ruggedized for extreme conditions
•  Designed to MIL-STD-810G; GVT Safety Confirmation for worldwide deployment
•  Transportable by land, sea, and cargo air

Adherence to operation and safety protocols will yield optimal performance from the Li Expander Pak
for many years. Procedures for operation, preventive care, and maintenance are in this manual.

Please read this manual thoroughly before operating the Li Expander Pak.

Advanced Battery Management System (BMS)

The 24VDC Li Expander Pak consists of LiFePO

4

cells and an advanced battery management system

(BMS) that performs two vital functions:

• The BMS manages the battery functions and promotes healthy cycling at the cells.
• The Protection Circuits protect the cells (and the operator) from dangerous conditions related to

cell voltages, temperatures, and current flowing in/out of the battery.

When all of the operating conditions are satisfactory, direct current (DC) can flow in/out of the battery
cells (cycling). If the temperature, voltage, or current is outside of the preset limits, then the BMS
Protection Circuits engage and remove the cells from service by disabling the battery at its terminals
until proper operating conditions are restored.
