Fully charged the battery last night, shows range at 361 miles. Also noted the remaining range before recharge and added miles covered since previous and that totalled 362 miles. As yet no seeing any deterioration. Apparently 20c is the ideal temperature for BEV,s, taking into account optimum battery temperature and use of Air conditioning/heating. In actual fact the range is now around 20 miles higher than July, during the heatwave.
