I noticed a significant drop in EV range over my first winter with my Clarity, as low as 35 miles at full charge. So, I decided to collect my own EV range data and am reporting here that data for the past 5 months. I charge it in the garage, and noticed two trends: 1) there is a strong temperature dependence of EV charge range, with colder being worse; and 2) there's usually a negative effect of complete discharge, in that the next few charges after a complete discharge to 0 EV miles are often lower in EV range. The charts are self-explanatory, but in essence, the EV range goes from around 38 miles at 48 F, to around 50 miles at 70 F. I haven't gotten warm enough temperatures to report a peak (optimum) charging temperature. I'd be interested if others have similar data.
