The secret to maximizing EV range in cold weather is to drive faster
Geotab has explored this subject extensively and found that temperature affects range both positively and negatively. This means that at optimal temperatures the vehicle’s range can increase by up to 15%, and on extremely cold days it can be almost halved.
Speed is another important factor. This is because as speed increases, drag increases. Common sense would suggest that this would mean a reduction in cruising range. While this is true, once the temperature drops below 32 degrees he seems to have a positive effect on increasing speed, up to a point.
The company has created models based on EV sedans and cargo vans. We analyzed his 350,000 trips from 500 sedans and his 2.8 million trips from 2,000 vans. This equates to over 500,000 hours of his driving analyzed, assuming all models were calibrated to represent a 65 kWh battery pack and constant speed.
