set charge to 80% on 2025 Leaf?

Someone could make a gadget that sits over the third blue light of the charge status lights on the dashboard. When the third blue light starts blinking (at 67%), an adjustable timer counts down and then terminates the charge somehow. If the gadget was connected via wifi, then it could notify an app (for those chargers that have one), like my Chargepoint that it was time to stop charging. Somehow.

If one wanted to stop an L1/L2 charge by opening the control pilot wire behind the J1772 socket--would this shut down the AC to DC charger normally?

We almost always use the 80% setting. And I wish this were an option for laptops, cell phones, kindles, etc.

I’m driving 2019 SV with 100k km on it. Never thought about 80% charge, using provided charger at home as needed and still has 251km range out of battery.

Do not overthink Japanese engineering

You may not be aware that the 80% "long life mode" was put there by Japanese engineers, and only removed after US EPA penalized this by rating the Leaf's estimated range based on the 80% charge. So Nissan removed the 80% setting, in order for the EPA sticker to reflect 100% range.

Wow crazy, good to know!
 
look on the time to charge to 75%...add ~20-30 mins to that time for ~80%, then set timer for those hours.
That is what I do as well, takes 20 seconds to set the timer. Another rule of thumb I use for my 40 kWh LEAF is one hour on level two charging equals 16% added to the battery charge level.

My 2023 Leaf has never reported anything on the time to charge screen. Anyone know what I need to ask to be done?
If your 2023 Leaf was built on or before November 6, 2022, it probably has exactly the same problem as mine.
Here's the link to the NHTSA TSB;

Note that you can quickly identify the bad meter, as it shows an 80% division instead of 75%.

I'm still trying to decide if I'll have it replaced, or just live with it.
(After six months, I'm leaning toward just living with it.)

The EPA must have changed their policy somewhere along the line. The 2021 Ford MachE onward allow the user to set the target charge and the EPA rating remained unchanged.

Pity Nissan never re-enabled the feature.
 
I have the ENELX charger discussed and pictured.
The "starting energy" (36% in photo) must be set manually.
The app then simply calculates how many KWH to add based upon the "target energy" you input and the battery capacity you have input into its data base (62KWH in photo).
The unit does measure how much energy it inputs to know when to stop the charge.
It serves the intended purpose but the unit does not get a charge level signal from the car.
By example, I once charged to 100% accidentally when I set the "starting energy" too low. It added the energy it calculated (too much) which blew past my 80% "target energy" setting. The Leaf BMS stopped the charge at 100%.
I wonder how the ENELX will work now without the app.

I wonder if the original Japanese engineering team who thought up the 80% is even still around. The Leaf was in design from about 2005-2008 ish, and preproduction 2009. If the team was disbanded--who else at Nissan would even care? The EV side of the car hasn't changed much since 2013 except for bigger batteries and more kW of motor inverter. It's like Nissan just forgot they had the best EV in mass production 10 years ago. What a wasted opportunity.

Yeah, we don't know why. Tesla has had UI to limit state of charge for ages. They even have UI affordances like this for day vs. trip: .

'17 and '18 Bolt had a hilltop reserve on/off setting. On limits charging to 88%. Off is 100%. '19 Bolt to current have a target charge level screen that lets you set it to 5% increments. I had a '19 Bolt for 3 years and the min was IIRC 40% (memory foggy).

My '22 Niro EV (just like earlier HyunKia BEVs) has a max charge limiter that's only in 10% increments. IIRC, min is 50%.

Lucid Air (as I pointed out at https://www.chevybolt.org/threads/b...tions.56439/page-2?post_id=987132#post-987132, you'll probably need an account there to see it):
"test drove a Lucid Air on Sunday at Electrify Expo SF (in Alameda). At the end, I asked to see the charging UI in the car. If you move the slider to daily, it selects 80%. The minimum their UI allows for is 50%." Their manual calls for setting the daily to daily or 50% to 80% for "general use".

Tons of other BEVs sold/leased as new in the US have some sort of SoC limiter UI.
