As a new emerging and fast growing technology, Internet of Things (loT) has been widely applied in many areas, such as health care, intelligent transportation and agriculture. However, in manufacturing, the IoT-based product lifecycle energy management (PLEM), which is still at its infant stage, has not caught enough attention yet. In order to better promote the development in this field, the framework and the potential applications of IoT-based PLEM are put forward in this paper, which aims at providing a roadmap to direct and guide the related research works in the future.
