Re: Lost a "high-voltage battery status" bar, down to 11

What you describe is my setup. However I have found that pre-cooling in the summer months often results in the 11th bar lighting up. The car does charge beyond 80% during pre-cooling. Even if the 11th bar doesn't light up, I can travel almost 14 miles on the 10th bar which indicates that the 11th bar was partially full.

During the winter pre-heating often depletes the 10th bar slightly, since the heater consumes more kW than the charger can put back in. During the winter after pre-heating the 10th bar disappears just 2-3 miles down the road.

I agree that if the Blink reboots during the evening it will not charge beyond 80% at that time.

I just went past 10,000 miles in 9 months of ownership. No detectable loss of capacity or distance I can travel 'per bar'.

If that's the criteria for battery capacity loss, then I guess mine is still good even though my SoC gauge says otherwise. When I charge to 100% now, it only goes to 83-85% which is 10-12% loss of capacity. However, I can get 14 miles on the top bar and another 11 on the eleventh bar so I doubt if this is a good indicator of capacity loss. I also drove 50 miles on just the bottom two full bars and still had 4.6% left when I arrived home. VLBW came at 8.5%. Turtle would have been 1.4%. I've had my 'EVBS' light come on three times in the last couple weeks, so I know I have some bad cells/module.

If the EVBS warning light is coming on I imagine codes are set in the computer that a dealer should be able to retrieve.

Because there is charge/discharge possible during preconditioning, it's normal for this to happen if you operate preconditioning for a longer time. (Leaf reaches set temp, so extra charge capacity makes it into the battery)

Of course, since you are going to immediately use this charge it's of no consequence for pack aging.

By nissan's standards, I abuse my battery as well, probably worse than azdre....and live in phoenix... guessing I won't be far behind in capacity. Mine is 15mo, but only about 13k miles.

You keep your battery at 100% most of the time, or only half the time?.. how long does the battery stay at 100% everyday?

We charge to 100% every night. Top off about 70% of the time each a.m. after about 3 miles (wife going for coffee and bagels). Then drive/charge/drive during the day--not to 100% there is not enough time between turnarounds. Ironically, maybe that 3.3 on-board is a good thing--otherwise it would be 100% every time car is parked :P .

Going on 1 year in June with 19,000 miles. Battery performs like day 1. No problems or loss of capacity or power. Nothing to report, folks.

Another data point....

I just lost a bar this weekend. I have had my Leaf almost exactly one year. Mileage is 13,633. I live in the Phoenix area and charge to 100% every night. I have never used a DC Quick Charge. I had my one year dealer checkup about two weeks ago, and got the "5 stars" rating, display still showed 12 bars.

Regards,
Brett

Thanks for sharing Brett, have you noticed any drop off in range?
