Technical report: Measurements of cold climate EV charging

Abstract

This research project aimed at providing further understanding of electric vehicle (EV) charging in a cold environment. The report provides laboratory measurement results and acts as supporting documentation for the raw measurement data. The laboratory measurements were executed at a large temperature-controlled vehicle technology laboratory, and the charging measurements were logged from a three-phase power analyzer. The testing comprised four battery electric vehicles (BEVs) and a single plug-in hybrid electric vehicle (PHEV). All cars were tested at 20 °C, 0 °C, -10 °C, and -20 °C. The results describe the charging behavior of each vehicle under different ambient temperature operating conditions. The further analysis of the results is included in a separate research report.
