Lithium-ion batteries have become ubiquitous in consumer electronics, cordless power tools and electric vehicles. The global lithium-ion battery market surpassed $23.5B USD in 2015 and continues to grow at a rate of 17% per annum. A fundamental limitation to widespread technology adoption, however, is cost of ownership, which is driven up by the limited lifespan of the batteries.
GBatteries proposes to develop and implement an Active Battery Management System (ActiveBMS), an innovative technological approach for battery management that enhances battery performance by optimizing ion flow. ActiveBMS uses a proprietary charging method, reducing degradation and increasing battery cycle life by a factor of four compared to charging using conventional methods. The technology works by measuring a battery’s interface conditions and actively managing its charge in real-time, safely enabling improvements in reliability, charge rate, and cycle life. Using ActiveBMS, charging rates can be increased by at least six times over conventional methods with no adverse effect on battery performance, thus achieving a 50% charge in five minutes and an 80% charge in ten minutes—a point of particular interest for electric-vehicle applications.
