ENIAC - BattMan - Battery Management with Solar Powered Devices

The BattMan project focuses on the battery, charging, battery management and communication elements of solar-powered, off-grid street lighting poles. The novel off-grid street lighting poles are specified, simulated, designed, prototyped, and will be demonstrated and validated in the project. The objectives of the BattMan project are to develop: -Improved battery chemistry, battery cell design and battery pack design for cost-efficient, predictable, reliable, safe, corrosion resistant and long life operation -Improved and cost-efficient battery management systems (BMS) for ensuring specifications, including state-of-health (SoH) and state-of-charge (SoC) reporting, cell balancing and temperature stabilization -Enhanced efficiency of the overall energy chain in the system, including maximization of system performance for both the application requirements and battery lifetime -System integration of electronics with photovoltaic panels, PV optimization and the application of systems to allow support of the smart grid over the internet -System and prototype designs for the demonstrator application of the Solar-powered Off-grid Street Lighting with communication capabilities. The developments within this project, especially for the battery management system (BMS), energy management system (EMS), and generic system designs, will be used to support a variety of applications (electro mobility, renewable energy, DC micro grids).

Batteries and battery management systems are the essential storage elements in any solar-powered application. These systems can be employed in a variety of different markets and applications, as will be described below, yet reliable long-term service of t he battery and system is the common challenge for all of the applications. The BattMan project focuses on these essential elements and targets solar-powered, off-grid street lighting poles as a challenging demonstrator. It will be specified, simulated, designed, prototyped, demonstrated and validated in the project. The relevance of BattMan to ENIAC?s objectives is targeted at SP3 ? Energy Efficiency ? where Grand Challenge 3 ? Reduction of Energy Consumption ? is specifically addressed. In addition, t he solar-power-charged battery packs form part of a scalable concept that can be used for off-grid and on-grid applications. The concept can be applied to electric mobility applications that integrate lighting, fast charging stations, solar panels, distri buted storage units, communication capabilities and is a part of the smart grid and Internet of energy applications. This links to SP3 - Energy Efficiency, Grand Challenge 2 - Energy Distribution and Management - Smart Grid and we expect that the battery technology and management systems being developed will support the next generation of electric vehicles? needs with installed car-roof solar panels or electric car charging stations. This is targeted by SP1 - Intelligent Electric Vehicle -, Grand Challeng e 1 - Intelligent Electric Vehicle.
