Software defined batteries

摘要: Different battery chemistries perform better on different axes, such as energy density, cost, peak power, recharge time, longevity, and efficiency. Mobile system designers are constrained by existing technology, forced to select a single chemistry that best meets their diverse needs, thereby compromising other desirable features. In this paper, we present new hardware-software system, called Software Defined Battery (SDB), which allows integrate batteries of chemistries. SDB exposes APIs the operating control amount charge flowing in out each battery, enabling it dynamically trade one property for another depending Application And/Or User Needs. Using microbenchmarks from our prototype implementation, through detailed simulations, demonstrate is possible combine individually excel along axes deliver an enhanced collective performance when compared traditional packs.
