Boston-Power Launches Ensemble™ Module System

Highly Scalable, Highly Reliable, "No-Weld" Integration System for Automotive and Industrial Battery Module Solutions

WESTBOROUGH, Mass. and BEIJING, CHINA, Sept 16th, 2014 - Boston-Power Inc., an industry leading developer and manufacturer of lithium-ion (Li-ion) batteries and energy storage technologies, today announced its launch of the Ensemble Module System; a revolutionary "kit" of standard components that allows OEMs and pack assemblers a simple, cost-effective way to assemble large format battery pack solutions for electric vehicle (EV) and energy storage system (ESS) applications. 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.
