Batteries are of vital importance for storing intermittent renewable energy for stationary and mobile applications. In order to charge the battery and maintain its capacity, the states of the battery - such as the current charge, safety and health, but also quantities that cannot be measured directly - need to be known to the battery management system. State estimation estimates the electrical state of a system by eliminating inaccuracies and errors from measurement data. Numerous methods and techniques are used for lithium-ion and other batteries. The various battery models seek to simplify the circuitry used in the battery management system.

Enhanced living environments employ information and communications technologies to support true ambient assisted living for adults and people with disabilities. This book provides an overview of today's architectures, techniques, protocols, components, and cloud-based solutions related to ambient assisted living and enhanced living environments. Topics covered include: an introduction to enhanced living environments; pervasive sensing for social connectedness; ethics in information and communication technologies; service scenarios in smart personal environments; technological support to stress level monitoring; big data systems to improve healthcare information searching over the Internet; sensors for wireless body area networks; linear wireless sensor networks and protocols in next generation networks; model-compilation challenges for cyber-physical systems; health monitoring using wireless body area networks; wearable health care; and intelligent systems for after-stroke home rehabilitation.

The practice of Model-based Systems Engineering is becoming more widely adopted in industry, academia and commerce and, as the use of modelling matures in the real world, so the need for more guidance on how to model effectively and efficiently becomes more prominent. This book describes a number of systems-level 'patterns' (pre-defined, reusable sets of views) that may be applied using the systems modelling language SysML for the development of any number of different applications and as the foundations for a system model.
