Electra Motor Corporation is in the business of developing and selling high power lithium ion battery packs,**and complete electric drive systems for transportation applications. One of the key technologies for lithium ion**battery packs is the complex battery management system (BMS). To be competitive in this market it is**essential to develop new technologies to improve the performance of the BMS. Electra 's advanced BMS**technology has the ability to store and process real time data with ultra-fast computational speeds. To use the**technology efficiently, however, advanced algorithms, which allow for rapid calculation of battery properties,**are highly desired. Furthermore, it is important to have a rigorous understanding of the variations in the battery**model parameters while the battery ages. Extensive battery data allow for determination and updating of the**model parameters. In this NSERC Engage project UBC's principle investigator Professor David Wilkinson and**his team will work with Electra Motor Corporation staff to conduct a detailed experimental program to**establish key operating parameters for lithium ion batteries to enhance the performance of an advanced battery**management system. To maximize the performance and lifetime of lithium ion batteries it is essential to**understand what operational factors most significantly affect the state of health (SoH) of the battery pack.**Once a thorough understanding is developed, detailed algorithms can be developed for Electra's advanced**battery management system to control a lithium ion battery pack in order to maximize performance and battery**lifetime.
