10 week hiatus every summer... charging strategy

Thu Mar 03, 2011 8:59 am

My situation is that I am going to own a Leaf that will sit in my Delaware driveway every summer from June 1 until August 15 for the next several years while we travel 1200 miles to our summer home in Canada. I am wondering if anyone has heard anything about the correct way to deal with this situation. Will this down time have a negative impact on the battery, and if so, is there any way to minimize this problem? Thanks in advance for any knowledgeable advice.

plug it in, log into carwings once a week to boost charge it for an hour or so. try to maintain SOC at 50-60%

Off the top of my head I'd:

1. Buy a 0.8Ah deltran waterproof battery tender for the 12v battery.
2. Set the traction battery charger to charge once a week to 80% max for about 30 minutes (you might get away with less than 30 min since the 80% would be automatic).

You might not need to do # 1 since I believe the traction battery will keep the 12v battery floating.

As an alternative, you can check the charge status on the web and turn it on via the web when it gets to 30% state of charge. Easy to do.

You should be fine if you charge to 80% and let it sit. I would put a GOOD quality trickle charger on the 12V battery and leave it on the entire time. The models below are good brands and are both reliable and won't damage your battery. I would go with the first one as it is more versatile.

I have used both brands for equalizing Ev packs and have validated their curves for lead. Do not buy a cheap battery charger.

I also use this one but if the power drops it may not default to the SLA curve.

Good idea - though it can be done anpther way. Setup the charging timer for once a week charging to 80%.
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

I would caution using the battery tender brand mentioned above as I have used it before as one failed and the charge curves were are not accurate on the two I checked after testing. The first model I listed is quite durable and works well.

Until we've experienced something indicating otherwise I would not get any trickle charger for the 12v. Manual states that 12v battery gets a 5 minute charge every 5 days when the vehicle is not in use.

Additionally, the manual states that they recommend charging the car every three months with the 80% method if it's parked for a long time. So sounds like you could just leave it but if you wanted to be on the safe side you could carwings-charge it sometime in the half-way mark, or maybe carwings-charge it once a month.

If you have an SL, and it's parked in your garage, put a 100W flourescent light on a timer, above the LEAF solar panel. Run it for 4 hours/day; that should maintain your 12V battery (at least that's what the Solar Panel's supposed to do).

I have left my LEAF plugged in at 80% charge for just over 5 days. On the 5th day, at an unscheduled time (not 12am timer), my TED system recorded a few hundred Watts of power flowing to the LEAF. I now suspect this was an Aux battery and general housekeeping cycle.

The "proper" way to care for your LEAF for that period of time is to let a friend/neighbor use it! :D

Bring it to Canada and do your own LEAF tour. :lol:

People need to see that car driving around up here, but 1200 miles? Yeah, not unless you could tow it, or perhaps let someone else you know drive it for the time being?

The answer you're looking for has been pretty well answered already by many forum members. My guess would of been that it's just a matter of plugging in your 110-Trickle Charger or 220-Home Charger and set the LEAF to charge to 80%. I don't know why others are saying a trickle charger, I suspect that Nissan has made this quite simple and foolproof. As others have said: the LEAF automatically does a charge on the 12v battery, so leaving the car plugged in to maintain that 80% because of the loss from the charge should be all that's required.

If you don't mind me asking; where in Canada do you call your summer home?
