The History of Spear Power Systems

In 2005, Jeff Kostos and Dr. Joon Kim launched Kokam America. Kokam America was established to bring lithium-ion cell technology to the United States, and that goal was realized as the first cell manufacturing facility opened in 2008. After continued growth and additional partnership with Dow Chemical, the pair formed Spear Power Systems in 2013. Since that time, Spear has developed powerful new battery storage solutions and battery pack integration techniques and technologies.

Our Chemistry-Independent Approach to Battery Cell Selection

Spear takes a chemistry-independent approach to cell selection in order to ensure that your project uses the best cell for your needs. While some other battery manufacturers push only the cell chemistries that they create, Spear is able to leverage their experience in cell production to identify the best fit and secure those cells from a conglomerate of reliable cell manufacturers for the best price point. After selecting the optimal cell chemistry for your application needs, Spear’s team designs your solution to meet your space and weight requirements with unmatched efficiency. Where our competitors have designed a standard module that is difficult to alter, Spear’s battery modules are able to be adjusted to your requirements without compromising battery performance.

Spear also works closely with you to ensure that your application is unfailingly safe. Utilizing a novel in-house design, the Spear battery management system (BMS) monitors the status of your application to notify you if any aspect of your application’s performance is out of the norm. In addition to advanced monitoring, the BMS has numerous failsafe measures in place to identify and lock down any problems before they can cascade throughout the system. Spear has even designed a system that is able to quarantine a failing cell and prevent thermal runaway from propagating to adjacent cells.
