Battery Management Systems Workshop

Workshop notes and presentations are available here.

Monday September 26, 2011


Over the last few years, hybrid gasoline/electric and pure electric powertrains have emerged as legitimate contenders for ground and air vehicle fleets. A common element of hybrid and pure electric powertrains is a large capacity secondary (rechargeable) battery system. Weight and volume constraints impose practical limits on the useful range of the electric vehicles. Performance of batteries is impacted by environmental conditions such as ambient temperature. Furthermore, battery degradation and aging concerns impose bounds on charge/discharge currents or discharge depths. As a result, battery management systems (BMS) have emerged as a necessity for transportation and mobility applications. The primary emphasis of BMS research is to extract maximum performance from rechargeable batteries while minimizing degradation and extending useful life. Specific research topics under BMS include:

  • Physical and chemical basis of cell degradation
  • State-of-charge estimation for various cell chemistries
  • State-of-health estimation for various cell chemistries
  • Remaining useful life estimation for battery systems
  • Cell, module, and system-level performance monitoring
  • “Fuel gauge” applications for primary and secondary batteries
  • Innovative charge/discharge management and control systems at cell, module, and system levels
  • Battery usage monitoring for warranty assurance
  • Range-extending control strategies
  • Managing power demand from battery charging systems
  • Cell monitoring and cell balancing management for certain chemistries

Research relevant to BMS is conducted in universities, government labs, and in private R&D facilities owned by battery manufacturers, vehicle manufacturers, and transportation system integrators. The PHM Society is proud to announce the first public forum dedicated to bringing all interested parties together and to discussing the state-of-the-art, technical limitations, and future research directions in this field.

The goal of the Battery Management Systems Workshop is to discuss the emerging art and science of battery and power management for electric and hybrid vehicles as well as other mobile applications. A secondary goal is to document and benchmark the state-of-the-art in battery SoC and SoH estimation. A third goal is to discuss methods and strategies for acquiring public-domain data sets and performance models for battery usage and aging that can be used to benchmark future efforts in SoC and SoH estimation.

The Workshop will be conducted as a one-day workshop on Monday, September 26, 2011, during the Annual Conference of the PHM Society 2011 (PHM’11). Registration fees are $50 for registered attendees of PHM’11 and $200 for those who are only attending the BMS Workshop.
