This report details preliminary results of the testing plan implemented by the Hawaii Natural Energy Institute to evaluate Electric Vehicle (EV) battery durability and reliability under electric utility grid operations. Commercial EV battery cells are tested in order to assess the impact of vehicle to grid and grid to vehicle applications on cell degradation. The plan also includes testing other usages associated with EVs under grid operations such as the impact of charging level and charging habits. This report first details the procedure used to analyze the electrochemical behavior of the cells and then provides an update on the testing status as well as preliminary visualization of the data gathered so far.
This report is meant to provide an update on the ongoing battery testing performed by the Hawaii Natural Energy Institute to evaluate Electric Vehicle...
Electric vehicle (EV) batteries have significantly improved since their inception. However, lifetime of these batteries is still strongly dependent on...
