International Battery Provides Green Lithium-Ion Energy Storage Solution to U.S. Marine Corps


ALLENTOWN, Pa - International Battery (www.internationalbattery.com), a U.S. manufacturer, designer, and developer of large-format Lithium-ion rechargeable batteries and grid-scale systems, today announced that it has teamed with prime contractor, HDT Global (HDT), to supply energy storage systems for the U.S. Marine's Ground Renewable Expeditionary Energy Network System (GREENS). A production run is currently underway after a nine month development phase. The GREENS portable system provides renewable energy for forward-deployed units that have a limited power supply. By creating a renewable source of power, GREENS reduces the amount of fuel needed for typical generators and will lessen the need for fuel resupply - reducing the associated threats to vehicle convoys such as in Afghanistan and Iraq.

The GREENS power systems consist of networkable and vastly scalable 1600 watt solar arrays and International Battery's rechargeable large-format Lithium-ion batteries that provide continuous electricity for Marines in remote locations and forward operating bases. International Battery's 60 Ah cells and Battery Management System (BMS) are the building blocks for the 24V, 1.5kWh system which HDT integrates into a ruggedized enclosure. The integrated renewable system, which can be transported on a Humvee and quickly assembled, provides AC and DC power needs to charge typical communication, targeting and computing devices while interfacing with existing diesel generators. The Lithium-ion component of GREENS supplied by International Battery enables high efficiency storage of solar energy in a package substantially lighter than a lead-acid battery solution. The lithium-ion battery also has eight to ten times the cycle life of lead-acid batteries, exhibits dramatically improved durability when operating at high ambient temperatures - which severely shorten the lifetime of typical lead-acid batteries - and allows for near 100 percent utilization of the nameplate battery capacity. International Battery cells and systems have also been thoroughly tested by the military for abuse and safety and have successfully passed all tests.

"International Battery's Lithium-ion batteries are the perfect solution for GREENS as their quality, reliability and functionality far surpass that of lead-acid batteries previously used for energy storage," said Mike Stolarz, HDT vice president of business development. "International Battery's support and technical capabilities were highly valued during the development phase and we're pleased to integrate their innovative battery technology for a comprehensive energy storage solution for the U.S. Marine Corps."

International Battery's large-format prismatic cells contain up to 5 to 10 times more energy than other prismatic cells and 70 times more energy than consumer-oriented cylindrical cells. This results in a less complex system with a more efficient electrical bus and low thermal management requirements, allowing compact packaging and good system energy density. The company's BMS monitors the temperature and voltage of each individual cell and provides continuous active balancing of the system maintaining all cells within a narrow voltage range. The monitoring of each cell makes the battery modules inherently more reliable and efficient than traditional battery designs.

"We're very pleased to work with HDT Global for this important mobile renewable power system for the U.S. Marine Corps," said Dr. Ake Almgren, president and CEO of International Battery. "We're seeing a growing trend of combining renewable sources with energy storage in the military and we're pleased to be once again chosen to deliver our energy storage solutions to the armed forces."
