动态电源管理——实现更快速、更高效的电池充电

Dynamic Power Management——Realization of Faster and More Efficient Battery Charging

平板电脑和智能手机等新兴便携式设备需求的快速增长,给电池供电型系统提出了许多新挑战。电池管理系统,必须能够智能地支持不同类型的适配器和电池化学成份,并且必须拥有高效的快速充电能力和良好的用户体验。本文将讨论如何通过动态电源管理(DPM),实现快速电池充电和提高电池充电性能,并介绍一些延迟电池使用时间的重要设计考虑。

The rapid increase of emerging and portable devices, such as tablet computer and smartphone, poses new challenges for battery- powered system. Definitely, the battery management system must support different types of adapters and battery chemical compositions intelligently, and own the features of fast and efficient battery charging and good user experience. This paper is going to talk about how to realize fast battery charging and improve battery charging performance through dynamic power management （DPM）. Meanwhile, some important design considerations for extending battery life will be introduced as well.
