We normally end the day with between 93 and 73 miles. We could not plug in for three days if we wanted, but we charge every night because we think it's better for the batteries. Our concern is that if we never fully discharge the batteries, is this shortening their life? Also, if we can't use 100 miles, how would we ever use 200 miles? Plus, we'd be paying alot of money for something we'd never use. Of course, this is not everyone's situation. Some people need a 200 mile range. Therefore, we suggest that Nissan consider offering an option of a shorter range and a longer range in future vehicles. That is, in the urge to develop a longer range vehicle, don't assume it's for everybody or that the current range is insufficient. We intend to buy another one in the future and would like to keep the costs down by not buying more battery than we need. Keep the current range and offer a longer range option for those who need it.
Very similar to me. Key is that 99% of the time I'm charging to 80%. Much better for efficiency overall as well since you get maximum regen from the start. Not having maximum regen for me can really hurt efficiency for me especially as I live on a small hill. And others have noted that since the charge rate slows down near the end when charging to 100% that also seems to lead to less efficiency.planet4ever wrote:My two rules are:
- Plug it in if I'm down to 6 bars or less.
- Charge to 100% (regardless of bars left) only if I think I might be driving more than 50 miles the next day.
I think it's doable. I was also thinking an adjustable charger would be really nice, something that allowed the user to choose between slow and fast charging, optimizing battery life when there is plenty of time but also allowing for occasional fast charging in a pinch.LKK wrote:I love the idea of a consumer being able to pick and choose the battery that best meets their requirements. Why pay for more range than you really need?
Does anyone know how much power would be needed to charge a 200 mile battery in say 8 or 10 hours and will normal home wiring support this? My guess is it wouldn't take much more than running an electric range, so I would think it possible.
Sure, no sweat. Just update the charger in the car from 3.3 kW to 6.6 kW, and use any of the standard 30A charging docks and you've got it. If you have a wall mounted EVSE then it's almost sure to be on a 40A circuit, and that is all you would need. Well, not counting the really big ticket item, the 50+ kWh battery in the car! (More weight means it has to be more than twice as big.)LKK wrote:Does anyone know how much power would be needed to charge a 200 mile battery in say 8 or 10 hours and will normal home wiring support this?
