editor’s choice growth between 2010 and 2015. Pike Research’s report, “Advanced Batteries for Portable Power Applications”, analyzes existing and emerging portable battery technologies in depth across 15 consumer and industrial application segments and 17 primary and secondary battery chemistries. The study includes attribute maps for the most common battery chemistries operating in the portable power segment. Key industry players are profiled in depth and granular market forecasts, segmented by application and world region, are provided through 2015. An Executive Summary of the report is available for free download on the firm’s web site. the same power consumption of five US homes or small retail and industrial facilities. ABB has determined its existing power quality filter (PQF) inverter can be used to charge and discharge the Volt battery pack to take full advantage of the system and enable utilities to reduce the cost of peak load conditions. The system can also reduce utilities’ needs for power control, protection and additional monitoring equipment. The team will soon test the system for back-up power applications. “Our tests so far have shown the viability of the GM-ABB solution in the laboratory and they have provided valuable experience to overcome the technical challenges,” said Pablo Rosenfeld, ABB’s program manager for Distributed Energy Storage Medium Voltage Power Products. “We are making plans now for the next major step – testing a larger prototype on an actual electric distribution system.” International Battery Provides Green Lithium-Ion Energy Storage Solution to US Marine Corps Panasonic Introduces High Rate Lithium Ion Cell Panasonic has introduced a new high rate lithium ion cell, the CGR18650CH. The cell’s nickel manganese-based cathode material delivers higher discharge rates and better energy density and voltage than comparative cells. CGR18650CH cells are suitable for multi-cell applications. The CGR18650CH has a high discharge rate capability of up to 10 amps and a 2,250 mAH nominal capacity. The battery also features high energy density and voltage, a wide operating temperature range and excellent cycle life. GM and ABB Demonstrate Battery Re-Use Applications Earlier this year, General Motors signed a definitive agreement with ABB Group to identify joint research and development projects that would reuse Chevrolet Volt battery systems, which will have up to 70 percent of life remaining after their automotive use is exhausted. Recent research conducted by GM predicts that secondary use of 33 volt batteries will have enough storage capacity to power up to 50 homes for about four hours during a power outage. GM and ABB have demonstrated an energy storage system that combines a proven electric vehicle battery technology and a proven grid-tied electric power inverter. The two companies are building a prototype that could lead to Volt battery packs storing energy, including renewable wind and solar energy, and feeding it back to the grid. The system could store electricity from the grid during times of low usage to be used during periods of peak demand, saving customers and utilities money. The battery packs could also be used as back-up power sources during outages and brownouts. Using Volt battery cells, the ABB and GM team is building a prototype system for 25-kilowatt/50-kWh applications, about Battery Power • September/October International Battery has teamed with HDT Global to supply energy storage systems for the US 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 1,600 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 24 V, 1.5 kWh system that 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 10 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. 6 www.BatteryPowerOnline.com http://www.BatteryPowerOnline.com
