Lithium-ion battery manufacturer Boston Power, who recently raised some $250 million for further expansion, announced a new product.

The Ensemble Module System is a LEGO-like block, which enables the building of large battery packs for different applications:

“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.”

Inside those modules are Boston Power’s Swing 5300 cells with 207 Wh/kg energy density.

According to the press release, the Ensemble Module System is fully tested to automotive quality standards, so maybe some of electric vehicle makers will try to implement this solution.

Darren Bischoff, Director of Business Development and Marketing for Boston-Power stated:

“The Ensemble Module System offers a game-changing approach to building large battery packs for our customers. 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.”

Boston Power announced also that sample, prototype and production volumes are currently available.

    So how do their 207 Wh/kg energy density compare to competition?

    1. Rob Stark says:

      Tesla is at 245 Wh/kg.

      Currently, Tesla is unable to supply anyone else other than MB though.

      Then there it the matter of price.

      1. Richard Gozinya says:

        There’s also the matter of TSL energy density, which is quite a bit different than what’s at the cellular level. Don’t know what these would be, but Tesla’s is about 135 Wh/kg. As far as anybody who uses the packs, the TSL density matters infinitely more. Cell level density only matters to those who are building packs.

    Is there cooling duct in the picture? I can’t be sure.

    If cooling is invovled, then the modular design might NOT be so easy. Of course, since Nissan doesn’t use it and it won’t matter for people who lease the car, then it probably won’t matter if you don’t have liquid cooling.

  3. kdawg says:

    Looks like its the same length as the 18650 cell, taller, but thinner.

      The BP Swing 5300 battery cell also has very good cycle life. Here is the rest of the specs omitted from the pic in the story above:

    Better Place II?

    The return of the battery swap!

    Although lots of people must be enjoying the Tesla facility to do that, also.

    1. sven says:

      Nothing is the story above says or implies anything about battery swaps. Stop making things up.

      1. DaveMart says:

        Yep.
        I misread.
        Apologies.
