Charge Timer Question

Mon Feb 14, 2011 12:36 pm

Conditions:

Timer One
Start Time: 20:00
End Time: 10:00
Days: MTWTF

Timer Two
Start Time: 0:00
End Time: **:** (NOT set)
Days: SS

Charge assumption:

M - midnight->10:00 & 20:00->midnight
T - midnight->10:00 & 20:00->midnight
W - midnight->10:00 & 20:00->midnight
T - midnight->10:00 & 20:00->midnight
F - midnight->10:00 & 20:00->midnight
S - midnight->midnight
S - midnight->midnight

The EV Customer Support person I queried was unable to give me a satisfactory answer. She also indicated that, if the Leaf was plugged into a charger while within any of the timer ranges, charging would NOT start. This seems contrary to my actual experience, but then, I have very limited data.

Any advice/thoughts much appreciated.

[EDIT to fix Monday - thanks @garygid!)

And note that you cannot enter "24:00" as a time. It cycles back around to "0:00", which is confusing.

Apologies up front if this is covered somewhere here. But have little time at the moment, and it's probably not been covered. My real first forray into timed charging (not counting a short experiment in the first week).

Came home last night at 10pm. Set Timer 1 in car to END TIME 7:00. Did NOT set a Start Time and left default of 100% charge. Assigned this timer to ALL days. Plugged in to L1. Charging started immediately.

A few minutes later: browser update; 25% charge; plugged in and charging; 18 hours estimated.

All that makes sense and is as expected. The reason for the 7am stop time is ... rates go up at that time.

This morning: 07:30am: Car is still charging :shock: (First light solid; 2nd blinking.)

Browser update says: 67% charge; plugged in and charging; 7 hours estimated.

Climbed into car; ACC mode (2x power-on button); pressed NAVI (blue icon button lower right); then Charge Timers; screen says: Next Timer: Timer 1: ON Wed. End Time 7:00;
Current time: Tues 7:36am

Manually unplugged car.

Why did the car not stop charging ? Is it because the timer was created on Monday night and it knew that it can't reach 100% by Tuesday 7am ? Other reasons ? Pilot error ?

The Timer as set above now works.

However, for the third time now I am getting something else unexpected. As reported (off-topic) here: http://www.mynissanleaf.com/viewtopic.p ... 785#p65785

I am getting TWO notifications anytime I use the above timer setting, and it does not mater whether I do 100% or 80% (last night was 80%).

Could someone else confirm, please ?

Set *NO* Start Time, set End Time only. Plug in with enough hours to spare to ensure a charge completion by the End Time. How many notifications do you get ?

1st occurence: "Charge Complete" notify at 12:20am and 2:40am (100%)
2nf occurence: "Charge Complete" notify at 11:40pm and 1:11am (100%)
3rd occurence: "Charge Stopped" (not kidding!) notify at 3:44am and 5:00am (80%)

I'm guessing that it decides to charge until full going past the timer if needed if there isn't enough time to get a full charge. Might be nice to have an option that says "stop charging at end time whether or not charge is done" for those who don't need a full charge but the rate is more important.

I'm confused. What does the end time mean (used together with a start time) if it doesn't mean stop charging at that time?

It means make sure you finish charging by then.

In all three cases my End Time was set to 07:00am (rates go up after 7am). Notice that the notifies came *WAY* before reaching the End Time. It's possible ( I just don't remember ) that I disabled the timed charging on the first two occurences with the button to the left of the steering wheel so as to start charging immediately, and that's why "Charging Complete" happened so much earlier in the process (closer to midnight). On the third example I let the timer do all the work after the car got plugged in, and instead of "Charging Complete 12 of 12 bars" I got two "Charging Stopped 10 of 12 bars" (80% charge).

mwalsh reports above about ALSO getting TWO notifications ... but WHY ? Not only is it redundant, it's confusing, and it implies that the LEAF is doing an additional charge cycle (unsure how long the second one lasts) and pushing the battery that's already at 100% (in the first two cases). And ... if this is the case ... why does this NOT happen during an UNTIMED charge ? ( At least I have never seen two notifications during normal 100% charging ... only one (as expected). )
