Can leaf spy limit charge to 80%

[Rudynfld]

Hey there, just ordered my Bluetooth ODB from Amazon. Want to get two main things out of this, number one I want to check my battery health for charging habits and make sure what I’m doing is best for the battery. The other thing is I want to tell if this feature that they stubbornly took out of charging the 80% is available via leaf spy I have a smart charger but Wi-Fi is iffy on it and sometimes it won’t charge, or it’ll charge to a 100%. Cheers.

No.

The easiest way is the charge timer, I usually just add a little extra time to the 75% charge time estimate

I am currently trying to make a littlle thing that can do this, by have a microcontroller communicating with the Leaf over the OBD2 port and then sending the info to my charger. Currently though I am stuck at communicating correctly with the ELM327 to get some data out of the Leaf...

Where do I find that time estimate?

Leaf Spy cannot limit the SOC.

What year and model Leaf do you own?

I do a workaround to achieve 80% SOC but it's rather cumbersome using my Leaf's charge timer. Since I know my Level 2 charge percentage is 18.5% / hour, I set the charge timer to reach 80% before cutting off. Or, if I'm home, I just set my phone to time the interval and manually stop the charge.

As Steve52 said, we know that our L1 charging adds 5%/hour, so we plug in the car, calculate the required charging time on our fingers and toes, and set the timer on the kitchen oven. Then a few hours later we run around the house trying to figure out where that beeping is coming from. Good times.

If you have a set schedule, you can also take advantage of the charge stop timer.

Let's say that I leave the house at 7AM Mon-Fri. If I want to limit charging to 80%, I would set the charge stop timer for 11 AM Mon-Fri (i.e., 100% - (5% x 4 hrs) = 80%).

Then, on Sun-Thu evening (or when I get home from work) I plug the car in and it picks the time to start charging to get to 100% at 11 AM, meaning it will be at (approximately) 80% when I unplug the charger to leave at 7 AM. My lowly 2014 offers two stop charge timers, so you can program in additional flexibility if you have a more variable departure schedule.

This won't be perfect, but realistically it shouldn't matter whether you're stopping at 77% or 82%. The important thing is to not leave the battery at very low or very high charge percentage for prolonged periods of time.

The charge timer estimate is displayed in the middle of the dashboard (on a 2014 SV) when you shut off the car. I always assumed that other years have the same. Are you not seeing this?

I use a smart plug and can set the start and stop time from my smartphone.

I use Home Assistant along with my ChargePoint EVSE:
1- Look at the charge estimate on the dashboard to get to 75%
2- Launch Home Assistant from within Android Auto and start the appropriate script that will stop the charge after approximately that delay.
3- Charge the car.

Works well!

Until it doesn't. Damn cloud services with their accounts, timed security challenges, API changes.... I plan on eventually getting an OVMS when it properly supports 2018 and later models to bring everything locally and be done with it. Plus, go from 3 steps to 0 step.

I know about what it takes to get to 80% and I set the LEAF charge timer. Done. Early LEAF's had the 80 or 85% (forget) but Nissan dropped it by my 2015 SV. Timer works fine. The timer is a little cumbersome but I have it always set to charge at night, with same starting initial charge (approx) I end up near 80% give or take 5%.

My battery is MID LIFE with 75%..... I have been charging at park (free weee) while I ride bike, about 1 to 1.5 hours. That gets me to about 60 to 75%. I am happy undercharging. I think (in my mind) it is making battery maintain SOH.

• Car is going on 10 yrs old.
• Bought used 3 yrs old 12 bars, went to 11 bars after 6 mo.
• 11 Bars lasted 2.5 yrs may be less.
• 10 bars for almost 4 yrs. I am holding on to that 75%.
• I went without scanning for 2 yrs, but watching it more in last 1.5 yrs. 75% is holding.
• Is charging to 60-70% helping? I can't under do it too much with already limited range.
• I try and not get below 30% in the early days, but now I have to accept 15% or less even - - - -
• I'd like 150 mi range, car utility improved greatly for the way I drive, but it's a 2nd car. I have ICE backup.
• 75 mile range, if my only vehicle I'd have to sell it. Cost of tax, insurance makes a 2n5d car expensive. Think about selling LEAF.
• The unspoken benefit is savings on fuel and less wear and tear on the main car, VW TDI*.

* Just went on +1200 mile RT (turned out to be 1320 miles) with my "Clean Diesel". Left home with full tank. Filled up once on the trip, $3.25/gal. I get 47 to 55 mpg on highway. One stop and that was near destination!!!! Even if I had a 250 mi Tesla it would be at least 6 stops. Get this I was in South Carolina!!! I was near the Path of Hurricane Helene, about 20 miles East of eye. Power was out Friday AM and was still out when I left Sunday AM. As I drove looking off highway, no lights nothing. I had to turn around on Hwy 26 near Asheville, I40 was closed. Internet was spotty and did not know. My Garmin GPS told me to turn around. I back tracked and wasted 120 miles and 3 hours, and went through Atlanta.

In this scenario and you needed to charge an EV good luck. With that said gas stations were out, but one Shell which must have had a Generator and the lines were long. I saw it as I drove by on the interstate. I had over +700 mile range in tank so I could breath. Clearly liquid energy has advantages. I have two 5 gal gas cans. It has been a life saver. I have gasoline emergency Gen for home. One year power was out almost 3 days in summer. I was able to run frig/freezer, some lights, microwave, window AC in bedroom I thrown up for emergencies. I was very comfortable. Microwave was power hungry so have to off load Gen to run. People were having a rough go of it. I don't run Gen all day and night. I run it for a few hours at a time and charge 1000w power pack power station.. So I can still have lights and TV even with gen resting. I'd run it at night to keep cool in bedroom. Gen uses about 1 gal for 5 to 8 hours. I had about 6 or 7 gal, and by conserving it lasted the 2.5 days. Oil is life... Love EV's but I want my diesel car and gas generator as well. And no Helene was not cased by man, it was naturally occurring. Huge hurricanes were recorded in every century hitting USA since this data has been tracked. The issue is explosion in population especially living near the coast. Damages are greater. I am sick of non science, lack of facts, data, math, repeatable experiments not being referenced and "feelings" substituted. There are NOT more or stronger hurricanes in last 100 years. Some hurricanes in the 1800's set records yet to be broken.

This works if you commute, because you windup leaving the house at about the same time every day. Not so much if you don’t. I basically gave up on it. I don’t know when or if I will be driving and occasionally it’s 2am. And sometimes the car sits for 3 days. If there was a stop charging at X time it would be better, but afaik there is just the start one. IMHO it is one of the biggest weaknesses of the leaf. One would have expected it to be changed years ago. Maybe there is a patent block or something. If there is, Nissan could actually coordinate with leafspy to get around it.

There is a charge stop timer, at least on the first generation Leaf. Not sure which year you have, but I don't know why they would have taken it away on the newer Leaf. See my post above.

But, even with the charge stop timer you really need to be on a set schedule to see much benefit. If you might drive at any hour of the day, or not for many days, I don't know how you would predict when you want the car to stop charging.

I hope it doesn't seem like I'm picking on you with recent responses, but I grow weary of lazy right-wing talking points and as a human with a young nephew and two little nieces, I'm particularly sensitive to the future of the planet I live on and that they will (hopefully) be living on past the year 2100.

No reputable climate scientist will claim that any hurricane was "caused by man." What they will say, supported by sophisticated climate modelling based on decades of recorded data, is that human-caused changes to the climate (e.g., rising global air and water temperatures) make hurricanes worse, both at the point of landfall and far inland as we have seen with Helene. That process is the exact opposite of non-science, lack of facts, data, math, and repeatable experiments and really has nothing to do with anyone's feelings.

You're correct that major hurricanes have occurred throughout recorded history. Are there more now than in the past? Climate scientists say there are, but for the sake of argument let's turn the question around and ask how you would accurately and reliably determine the strength of a hurricane from the 1800s without satellite tracking, NOAA airplanes observing and measuring the storm, and a global network of weather stations recording data 24 hours per day? Perhaps you would use human casualties as a proxy for historic hurricane severity. In that case, does it seem like the storm tracking and path forecasting, which lead to the early warnings and evacuation notices that people get today might reduce casualty rates in modern hurricanes vs historic storms which often made landfall with little or no warning (e.g., 1900 Galveston hurricane, the deadliest natural disaster in US history)?
