Re: Range Issues

Running the Numbers the range chart the Elevation gain of almost 3000 feet, will use 4.5 KWH to clime. the 52 miles will take 12.09 KWH at 55MPH.so 16.5 KWHs for the trip. The DTE gauge is thinking you are on that hill I bet it is short! How many bars do you show at the end 1 or 2 fuel bars left? When I go up a hill I try to hold it to 3 power balls on the center dash, I read that some place it has helped in the past. that is a step hill for your last bit...

I show two when I roll into my driveway. It levels out to a slight grade about 2 miles from my house but the first bit is a hill climb. There is a meandering route on the old highway which is .6 miles longer speed limit is lower and it windy...I may try that tomorrow on drive home since I drove the truck today...

Two bars left is enough reserve in your mild climate. Just drive and enjoy!

OP: how much braking do you have on your trip home ?

You read my mind -- I thought to ask for a map ;-)

If you choose the bicycle route you can see that you have 3000 ft down and 5800 ft up.
Braking includes lifting your foot off the go pedal since regen will occur at about 50% KE recoup efficiency. If this is happening, perhaps you can try reaching the apex of hills a little slower so that the downhill portion does not lead to KE loss.

Wow. In Hawai, with a hot climate, in mountains, Sounds like your purchase is not the right one. Your Leaf will not hold up to your needs for long, and then you will be stranded...

This is not obvious to me.
OP: what is your battery temp when you arrive home ?

Why so disparaging? The OP is currently making their standard commute with plenty of charge to spare, and would have to lose quite a bit before leaving him stranded. Plus, the car spends the night at the top of a mountain, which is presumably cooler than sea level. The most heat would be generated driving home, but the car would have plenty of time to cool off in the evening.

Also, how hot is Hawai'i? According to Wikipedia, it's not all that hot. Which makes sense, since the tropical sun would be moderated by the surrounding ocean.

Yep.

A little physics also casts doubt on the @powersurge presumption
OP averages about 10 meters climb each km on the return trip, which works out to an extra
10*9.8*1600 = 156,800 joules per km
If a km takes 45 seconds (80 kph) then the climb home adds about 3.5 kW over and above a level terrain or around 12 kW total power draw if there is no braking. That sounds less taxing on the battery than being stationary and charging at 6 kW at home. For context, the LEAF draws around 14 kW at 62 mph and 22 kW at 74 mph on level terrain without any A/C
