Mine has the warning beeps too. The one drawback that I can see is that these beeps aren't that loud, and wouldn't necessarily be noticed from outside the car - especially if you were talking, or otherwise preoccupied. This isn't really different from the "headlights are on" sounds that many cars make, and people still manage to leave their lights on by accident.

For myself, I've become accustomed to a visual cue instead: if the dash is lit, the car is on. So far, I haven't had any problems.

 

The way they make the car to not shut off coz what happen if you were on freeway and your I-key went out battery

 

This is an interesting thread. I have a TCH, and have yet to leave it without shutting the power switch off ONLY because the energy display in the instument cluster, upon turning the power off, diplayss your avg MPG for the trip, and the word excellent flashes in the screen if it is above 35. If the NAH has the same display, let curiosity be a good reminder :-)

I left my TCH on for 3 hours, and found the lights on when return, the A/C was running too, had taken the hit on my MPG reading, so engine must have kicked in to maintain the charge, it still was on low side when I came back. But everything was fine after only mile drive.

 

We took the hit on gas mileage too. The one good thing about that warning that comes on when you hit E is that the engine will no longer come on to recharge the battery if you have left it On and walked away. So will come back to a dead battery, but at least there will be a couple of gallons of gas left to get home and recharged.

 

Now that consistency of NAH has come up?? My battery charge indicator never goes above 3/4 full, even at highway speeds and regen braking. Do any of you ever get a full charge indicated on your battery display??

 

The most I have gotten is about 7/8 full charged on the HV meter.

 

Based on my TCH experience, the way to get a full charge is via regenerative braking on a long downgrade. A full charge isn't really a good goal because once it is full you only have conventional braking which won't recover energy (friction or engine if shifter is in B).

 

I believe I read that both the TCH and the NAH intentionally only charge to 80% and a low of 40%. The reason is to protect and extend the life of the battery. More or less beyond those limits would get you a $3,000 replacement bill.

 

Thanks, maybe it is a placebo effect but I feel as though when i have a full charge (3/4) that i can accelerate quicker before the ice comes on. On a low charge (less than 1/2) the slightest feather pressure on the accel will turn on the ice. If this is true, it would be nice to have a battery that charged 100%
