So, recently, the remaining range on my car has been decreasing faster than seems appropriate. For instance, last night, my car charged to 151 rated miles and 172 ideal miles. (I have a 60kWh pack, and the charge limit is set to 80%.) By the time I starting driving it this morning, the range was down to 148/169, so I'll use that as the starting point. I drove only 35.5 miles today, using 16.9 kWh, for and average of 464 Wh/mile. (All three of those numbers are according to the "since last charge" meter.) My range was down to 77/88, for a decrease of 74/81 miles. By my calculations, using 16.9 kWh and the miles from the range meter, that makes a rated mile 238 Wh, and an ideal mile 209 Wh. Those seem very low, and the miles consumed seems very high. I thought a rated mile was based on EPA range, which makes it around 288 Wh/mile for the 60 kWh pack. At 288 Wh/mile, and 16.9 kWh, I should have only consumed 59 rated miles. Is it just calculating range incorrectly, or is there something wrong with my battery pack? Thanks.
