How to improve the autonomy of a notebook or a tablet? The classic approach is to integrate a battery with a charge capacity increasing. The problem, in almost all areas for the truth, is that the demand for energy is growing much faster than the technological development of batteries. Hence the idea of Microsoft to try a different path.
A team at Microsoft, led by Bodhi Priyantha, Ranveer Chandra and Anirudh Badam (top in the opening pic), is working on a new battery technology called “software defined” , whose aim is essentially to make the most of the solutions available today, not working on new batteries, but on a better integration with the operating system. Imagine a notebook in which fact of the “usual” lithium-ion batteries, they are mounted battery types, each optimized for a different type of load and charging profile . At this point the operating system can be instructed to use the appropriate battery depending on user activity. A long battery life and low power can be used to write lyrics or read mail, while a battery with more energy can be called upon for help only when you switch to video games or other software that make heavy use of system resources.
through a machine learning algorithm, the computer can learn the habits of use and is usually available when the connection to the grid, to optimize charging times and the choice of batteries: “ ie “, says Microsoft,” the system can learn the user connects the tablet to power every day at around 14:45, and then to 15 always carries a long presentation PowerPoint. This means that your computer needs to be ready to make a quick charge at that time, so that then the user can get to the end of the meeting in the afternoon “. Currently it is a technology still in the research project, but Microsoft hopes it will be integrated in the near future in its operating system. The research will be presented these days in the Symposium on Operating Systems Principles in 2015 which is held in California.
