Thanks to all for providing their range numbers. I'm in the market for a Leaf. Can you help relieve my range anxiety?
Summary: Driving 40mph (65kph) for 3 hours on flat ground at 90 degrees Fahrenheit (32 C), will I consistently get at least 120 miles (200km) range?
Detail: I live in Key West, Florida. The Leaf meets all my needs for driving in the Florida Keys. Every month or two, I drive to Miami and back, a 300-mile round trip. There are many level 2 chargers in the Keys, but the closest DC fast charger is in Homestead, Florida, 120 miles from my home.
The road out of the Keys varies from a 30mph speed limit to 50mph speed limit, with an 18 mile stretch where everybody drives 80 to get through it. Overall, it takes 2.5-3 hours to cover the 120 miles. There are traffic lights and occasional traffic jams. The road is very flat, and the temperature ranges from 75-95 degrees.
A typical trip might be: Drive 120 miles from home to the DC charger. Charge up to 80% in 40 minutes. Drive around town as needed. Stop at the same DC charger on the way home. Drive 120 miles back home.
I've never owned an EV, and I understand range varies radically based on driving style, speed, temperature, etc. Given the description above, do you think I'd consistently make the 120 miles from charger to home?
Hi I'm no expert as I've only had my MY2018 Leaf for 5 months. I live in Toronto, Canada area.
In your use case, the current 40kWh Leaf should do the job. You will for sure have to Rapid Charge at least once on the Miami trip. Maybe a second time, but with your driving stats you've explained, you should be ok with one rapid per leg. The issue is of speed as the faster you go, the more energy you use. 40kWh Leaf is EPA'd for 150 miles, but in warmer temps people are getting over 160 miles.
Now, for the daily use. 40mph is a low enough speed that this should not impact range very much, and the higher temps won't impact it either. Only on the fast charging where the BMS will throttle the amount of input rate based on temps. Since your daily is nearing the max range of the 40kWh Leaf and you are stating you will be daily DC charging, I personally don't think this version of the Leaf is your best bet. With that kind of daily use, I think it will stress out the batteries too much over time and lead to faster capacity loss than normal. So you can do it every day, however the loss of capacity may be quicker than a more easier use case.
My personal advise is to look at a Bolt, Model 3 SR or Kona (if you can wait for the Model 3 or Kona) for all BEV desire, or a PHEV Volt if you don't mind some gasoline use. The Bolt will give you your daily range no problem and allow for more consistent DCFC ing speeds, as well as maintain battery temps (with it's Active Thermal Management) to a more level state thereby prolonging capacity life. I am guessing that if you are considering the Leaf, that you are somewhat budget-minded. I understand the Bolt and these others will cost more than the Leaf and in your case, this would probably be better money spent.
Your use case seems to be right on the bubble of the Leaf's capabilities and for a long-term investment, I would lean away from the 40kWh Leaf. You can also wait for the 60kWh Leaf to come out if you are not in a rush, as we expect this to not only have 220 or so mile range, but have Active TM features as well. Not sure what the platform will be or look like, but I'm guessing at this point it will look the same as today's 40kWh Leaf.
Hope this helps. If you are only looking to lease a Leaf, say for 3-4 years, then it can make sense for you since you won't really care about any capacity loss since you are returning the car in a shorter time. However, the throttling for Fast Charging will most likely increase your travel times somewhat, since you will get the batteries nice and hot with your daily use and they won't cool down too much overnight since your ambient temps are still relatively high.
