Battery performance and Durability (EVE-14-04e, EVE-14-08e)
Mr. Olechiw and Ms. Marchington introduced EVE-14-08e, which reviewed the status of the USA and Canada’s work. Mr. Tom Casciani, the FEV consultant who is leading the literature review on battery durability was introduced to the group, presented EVE-14-08e and discussed the project timeline, structure of the literature review, resources, some literature examples, a preliminary list of factors effecting EV durability, test methodologies for EV batteries, and next steps. The review should be completed in mid-July 2015. A request was made to the group to provide additional international sources of literature on this topic, as the consultant is US-based (Action 9). Discussion focused on whether or not test programs were part of this research; Mr. Olechiw clarified that FEV will be offering recommendations that could include i.e. a specific test to be further developed, but right now were just conducting a literature review. Mr. Olechiw also clarified that this work was vehicle-level. Several comments were made about long-term aging factors, changing battery technology in the future, battery recyclability and concern over limiting technology. Mr. Olechiw noted that these were important considerations and that there would be no recommendations on introducing abuse criteria; rather, the purpose of the study was to inform the development of a standardized procedure to evaluate EV battery durability that reflects normal operation of vehicle, because this would ensure the vehicle would provide environmental benefits over a lifetime of operation.
