The highly configurable Swing Key block from Boston-Power is a series of interconnected swing cells in a robust mechanical enclosure. According to the company, this series brings to electric vehicle (EV) manufacturers for the first time an advanced battery solution that combines the safety and performance advantage of Boston-Power’s Swing cells with the capacity and ease of implementation of traditional large format cells. Capabilities of the Swing Key blocks include: >50% more usable energy density by volume and >45% more by weight; 10-year reliable calendar life; and wide operating temperature range down to -40˚C (-40˚F) discharge. The Swing Key blocks are currently in use in EV models, including the Saab 9-3 ePower.
