Low Power Modular Battery Management System with a Wireless Communication Interface

A Modular Battery Management System for HEVs

Proper electric and thermal management of an HEV battery pack, consisting of many modules of cells, is imperative. During operation, voltage and temperature differences in the modules/cells can lead to electrical imbalances from module to module and decrease pack performance by as much as 25%. An active battery management system (BMS) is a must to monitor, control, and balance the pack. The Uni...

A Low-power Multimedia Communication System for Indoor Wireless Applications

Flexible and Modular Low Power Wireless Networks

Driven by falling prices, continuous miniaturization and increasing functionality, low power wireless networks tap into new application areas. But an efficient utilization of embedded systems is hindered by lacks in interoperability and flexibility, because they are proprietary. In this paper, an approach for an abstraction layer in the area of embedded systems with respect to low power wireles...

Low Power Operating System for Heterogeneous Wireless Communication Systems

Operating systems in embedded wireless communication increasingly must satisfy a tight set of constraints, such as power and real time performance, on heterogeneous software and hardware architectures. In this domain, it is well understood that traditional general-purpose operating systems are not efficient or in many cases not sufficient. More efficient solutions are obtained with OS’s that ar...

Intermittent Wireless Communication System for Low-Power Sensor Networks

An intermittent wireless communication system has been developed for low-power sensor networks that improves sensor network efficiency by promoting cooperative optimization among the hardware architecture, communication protocol, and multiple access scheme. The intermittent communication protocol together with hardware for intermittent function contributed to reduce power consumption and extend...
