New Products * Batteries AllCell Launches Industry's First Stand-Alone Premium E-Bike Battery AllCell Technologies has launched of the company's Summit line of lithium-ion e-bike batteries. Unlike other premium batteries that are only available through the purchase of a complete drive train system, the Summit battery is available for purchase as a stand-alone product, expanding options for OEMs, retailers and consumers. Because of a variety of voltage and capacity options and the down-tube mounting location, the Summit provides maximum flexibility to support front hub, middrive, and rear hub motors across a wide range of power and drive-range requirements. An advanced proprietary battery management system (BMS) provides the Summit with CANbus communication capabilities to support state-of-the-art functionality and protection, including programmable operation and configurable communication parameters. The removable battery includes an easy-to-install two-screw mounting rail and standard connectors (Rosenberger and XLR), making it a well suited for most motor brands, conversions and replacements. With both 36 and 48 volt versions and capacity options of up to 17 Ah, the Summit meets the most demanding performance requirements in Europe and North America. Like each AllCell products, the Summit is protected by AllCell's proprietary thermal management material. Effective thermal management for e-bikes is becoming more important as the industry moves towards larger batteries while simultaneously packing more energy and power into each lithium-ion cell. The combination of using higher power cells and packing them into larger batteries is a recipe for reduced battery life and a higher incidence of thermal runaway and battery fires. AllCell's phase change material (PCM) effectively reduces battery temperatures and prevents battery fires, providing a great solution to the increasing need for thermal management in the industry. The Summit is available for pre-ordering now and slated for initial deliveries in early 2014. While the battery is available as a stand-alone product, AllCell is also partnering with motor manufacturers to offer fully integrated drive train systems for customers who prefer to buy a complete system. Tadiran Develops Rechargeable Lithium-Ion Cells for Remote Wireless Applications Tadiran Batteries has introduced the TLI series of batteries, a family of long-life rechargeable lithium-ion cells designed specifically for use in harsh environments. Standard rechargeable lithium-ion cells have inherent drawbacks, including short operating life (maximum five 18 Battery Power * November/December 2013 years), low maximum cycle life (1,000 cycles), high annual self-discharge (up to 60 percent per year), and limited temperature range (0°C to 60°C) with no possibility of charging at low and high temperatures. By contrast, TLI series batteries utilize technology found in Tadiran's patented hybrid layer capacitor (HLC), which stores the high current pulses required for two-way wireless communications, and has been field-proven in millions of cells to deliver 25+ year service life. TLI series batteries modify this technology to deliver reliable, long-term performance under extreme environmental conditions. TLI series cells can be recharged using DC power or can be used in conjunction with photovoltaic solar systems or other energy harvesting devices to deliver reliable long-term power. TLI series batteries are available in several standard configurations: AA-size (1550), 1530 and 1520, as well as custom battery packs. Encell Technology's Atlas 160 Nickel Iron Batteries Outperform VRLAs Encell Technology, a next-generation energy storage battery and electronics company, has introduced the Atlas 160 Nickel-Iron battery. This product is designed to replace traditional valve-regulated lead-acid (VRLA) batteries in demanding microgrid energy storage applications. Microgrid installations, consisting of a standby generator and solar energy panels, are commonly used to ensure continuous, reliable power in environments where utility power is erratic. Batteries in this application are frequently cycled and may undergo deep-discharge cycles. Battery life of VRLAs is severely reduced by sustained deepdischarge cycles. Typical specifications show reduction from over 5,000 cycles at 20 percent discharge to just over 500 cycles at 80 percent discharge. In contrast, the Encell Atlas 160 NiFe cycle life under similar deep-discharge operating environments approaches 9,000 cycles. For a typical installation, this extended deep-discharge performance can result in a dramatic reduction in the number of batteries needed without compromising battery life. The Encell Atlas 160 weighs 120 lbs and is packaged in the standard, front terminal configuration with maximum dimensions (5.3 by 22.3 by 13.0 in) similar to comparable VRLAs. High-end temperature ranges for both operation (100°C) and storage (60°C) exceed VRLA specs. Float charge battery life of the Atlas 160 is up to 20 years, several times longer than comparable VRLAs. When energy available over the entire cycle life of a battery is considered, the Atlas 160 product cost is one-tenth that of a lead acid battery with similar name plate capacity.
