New battery model also makes electric cars more reliable

Nano satellites weighing just a few kilograms orbit the Earth. Pivotal point of these miniature computers are their solar-powered batteries. Computer scientists at Saarland University have now developed a procedure that allows for better planning of solar battery operations. They are able to predict how much the on-board battery will in fact be utilized in the course of the satellite's mission. The efficiency achieved here is about five times greater than with conventional systems. And electric
