Thanks in advance for any input.
Several different points of view. From the point of view of the utility company, they would rather you charged in the night, 12AM to 4AM. That is when the grid has excess capacity, as demand is at minimum. Or in places with lots of solar, perhaps midday. Depends on the local power grid sources and loads. Evening is probably one or the worst, or the possible worst time, from a grid point of view.Honva wrote:Would it be better to charge to 80% in the early morning instead? My gut feeling is probably no difference at all. Want to hear from other experienced users. Re-charge the car in the evening is more peace of mind to avoid any surprises from overnight or early morning power outage
We generally say that if you charge to 80% it doesn't matter if the car sits afterward. However, given the looming possibility that the 40wkh pack will have serious problems with heat, I'd say that in hot weather you should let the car cool for as long as possible. That means having it reach 80% right before you leave for work. It may also mean only charging every other day, to let the pack cool as much as possible.My bad. When I said evening, I actually mean around 11pm.A time when demand is low. If it is not good to the battery, I could do 4:50-7:00 instead. Car is in garage which won't be too hot or too cold. If there are no significant difference, I would prefer to charge around 11:00 instead.
The climate in much of Ontario isn't a lot different from mine, so I'd expect some 90F days and some stretches of 80+ days and warm nights. It wouldn't take any more than that to degrade a heat-intolerant battery. As I wrote, they only need to worry in hot weather.alozzy wrote:The OP is from Ontario, Canada. Long before Ontario summer arrives, there should be plenty of feedback from owners in hotter climates about battery temps, accelerated degredation, etc. If it was me, I wouldn't worry too much about charging to 80% ish at anytime (whenever convenient), nor about having the pack sit idle at that SOC. The jury will be out by June/July...
I had this crazy idea today to bring my 15 Leaf to a car wash that I know has very cold water and use the undercarriage wash a few times to see if it would budge my constant 6 bar battery at all.LeftieBiker wrote:Balancing should occur with any charging level, but only happens at 100% charge, so plan on a full charge once a month, right before you leave for a drive. You're be best trying to keep the car roughly between 25% and 75%, and planning on charging only when the pack is cool. This sounds nuts, but thanks to Nissan's "engineering" I'm planning on putting an air conditioner in my garage so I can store the car in moderate temps during heatwaves. I'll set it for about 78-80F...
