That sounds about right. My own data shows that over 41 240V charge events, the average charging time is 2.6 hours with an average of 4.5 SoC bars remaining.Neal wrote:Did you know the average LEAF is plugged into a Charger for 9 hours but only charges for 2 hours a day?
If L2 restores 15 mph charging, the 31 miles = about 2 hours. 37 would be closer to 2.5 hours.SanDust wrote:These are somewhat different numbers than Nissan has released. Nissan has said the average daily driving is 37 miles rather than 31 miles. Not a huge difference but not the same. In either case the two hour charge can't be right because with a 3.3 kW charger you can't get the 10-12 kWh you need in two hours.
Very interesting presentation though with lots of facts.
LOL, of course you can! Who said you need 10-12? I've recharged to 80% many times in less than two hours! If it's at 5 bars left (48% actual), mine will charge 5 bars in about 100 minutes.SanDust wrote:In either case the two hour charge can't be right because with a 3.3 kW charger you can't get the 10-12 kWh you need in two hours.
If you have a 3.3 kW charger then, given that there will be an unavoidable loss of 10% inherent in the electrical to chemical conversion, assuming no other losses you can put 2.97 kWh of charge into a battery in one hour. In two hours that's 5.94 kWh. Going 30 miles on 5.94 kWh would require you to use less than 200 wh/mile, which isn't realistic. Going 37 miles would require you to use 160 wh/mile, which is surreal.smkettner wrote:If L2 restores 15 mph charging, the 31 miles = about 2 hours. 37 would be closer to 2.5 hours.
This is what you'd expect from a careful driver. You're using about 260 wh/mile so I'd say that you're not driving very aggressively and you're not driving very fast.IBELEAF wrote:My average during 6 month ownership has been as reported 2 hours and I have Blink unit, but then my average daily mileage is 22 miles which far below Nissan's average.
Charging 5 bars in 100 minutes would be quite the trick. Even if you only have 20 kWh usable that would mean you're ending up with 8.3 kWh in the battery in a little more than an hour and a half (5/12 X 20 = 8.333). Can't happen unless you believe that 1.5 X 3.3 = 8.3. Even if the charger was 100% efficient, which it isn't, you'd need two and a half hours (8.3/3.3=2.5). Since the charger will be at best 90% efficient, to get 8.3 kWh of charge into the battery from a 3.3 kW charger you'd need something close to three hours.LEAFfan wrote:LOL, of course you can!
