WMcIntyre Posted December 29, 2019 Share Posted December 29, 2019 Take into account ambient air temperature and battery performance. Select if car has been preconditioned vs cold start. Adjust charging times to reflect slower charging rates based on temperature. As most EV users have experienced, there can be significant increase in WHrs/mile (kilo) based on temperature. Moreover, supercharging in below freezing temperatures takes considerably more time. Link to comment Share on other sites More sharing options...
