Its a pity these cells are Lithium Cobalt and not the more friendlier chemistries. The spec states a charge temp from -20C! I didn't think Lithium cells like to charge below 0C.

Available in 155 Wh and 116 Wh increments, module designs can be created to meet a wide variety of voltage and capacity requirements. Companies in need of large format battery packs are faced with spending significant time and expense in designing, qualifying and fabricating custom solutions to meet their requirements. Boston-Power’s Ensemble Module System provides a semi-custom cell-to-module approach to quickly and easily integrate Boston-Power’s cells into high energy density battery modules. For OEMs and pack assemblers, the Ensemble Module System accelerates time to proof of concept, prototype and most importantly market while reducing upfront capital investment, program risk, BOM complexity, labor cost, production yield and operational complexity. “The Ensemble Module System offers a game-changing approach to building large battery packs for our customers,” said Darren Bischoff, Director of Business Development and Marketing for Boston-Power. “First, the flexibility of the Ensemble system allows customers to design, build and test a prototype pack in a fraction of the time it would typically take for a fully custom solution. Next, the production quality components used in the initial prototypes greatly reduce the pack qualification effort needed to launch into mass production. Finally, the same highly-reliable standard components used in the prototype and development stages support a cost-effective launch of low, medium and high volume packs without the need for expensive tooling or a complex assembly line. Ensemble provides clear value from project inception through high volume pack production.” Key to the Ensemble solution is its innovative pressure-connect approach to module assembly which completely eliminates the need for difficult, costly and time consuming cell welding. Fully tested to automotive quality standards, the result is a mechanically robust module that can be assembled and disassembled in a fraction of the time of conventional methods. By utilizing Boston-Power’s Swing Cell products, customers realize all of the ease of assembly benefits of large format modules while retaining all the advantages of packing density, reliability and thermal performance that come with using Boston-Power’s small form-factor battery cells. The Ensemble Module System enables cost-effective battery module packaging and mounting solution with exceptional performance at any volume. Sample, prototype and production volumes are currently available. The kits appear to be based on their 18650 lithium cobalt cells made in Shenzen: Swing® 5300 Cell Designed to meet the challenges of the EV automotive market, Swing 5300 offers: Optimized chemistry for higher operating temperature applications Equivalent capacity with long cycle life whether at 23C or 45C Wide operating temperature range Discharge -40°C to 70°C Charge -20°C to 60°C High energy density By volume: 490Wh/L By weight: 207Wh/kg 10 year reliable calendar life 1,000+ cycles at 100% DOD 2,000+ cycles at 90% DOD 3,500+ cycles at 75% DOD Fast charge with minimal loss of cycle life (80% capacity in 30 minutes) Unmatched safety features Patented CID Separator with integrated shutdown mechanism Redundant vents Aluminum can construction to optimize thermal dissipation Laser welded lid Certifications UL UN RoHS Nordic Ecolabel Chinese Environmental United Certification Center -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Boston-Power-Launches-Ensemble-Module-System-battery-pack-kits-tp4671843.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
