why can't Nissan do something similar :?


They can. They choose not to do it.

How far do you drive every day? There is nothing wrong with charging to 100%, as long as you don't leave it sitting at 100% for extended periods (especially in warmer climates). If your initial daily drive is enough to get it down around 80%, then just let it charge every night. Use the timer so it finishes just before you are ready to depart.


There actually IS something wrong with charging to 100% if you don't need that much range. No other EV does that by default. In warmer climates, any time at high SOC and moderate temperatures is not good.


While charging under the conditions mentioned is not good for the battery, Nissan did design it so that a 100% charge is needed on a regular basis to keep the cells properly balanced.

I use an early morning timer and the 80% option on my 2013 to hopefully maintain a healthy condition for my new battery. I do charge to 100% every 7 to 14 days, when I know that my initial trip for the day will get the charge level down to 80% or lower.

We have a wifi controlable juice box. I know the car well enough to know that if I am at 50 percent and I set the max current to X amount it will be charged to 90 percent the following morning. Takes 1/2 minute.

leftiebiker and webeleafowners,

Can you post links to the devices you use to limit charging?

Thanks,

The only devices I use are my brain and hands. I'll see if I can find a link to the WiFi plug device, but I don't know if I'll succeed...

EDIT: that was easy. Here it is:

The post above covers it. We actually own a juicebox that has all the same capability.

If you are just using 120 to charge go to Home Depot and buy a remote control plug thingy. Like you use at Christmas with the lights but for high current.

I saw on youtube lately that one guy was test driving the 2018 Leaf from 100% to 0% on a road test. He got the Leaf Spy connected as well. What he found was interesting. At 100% full charge, Leaf Spy showing 38KWh, there is a 2 KWh reserved room for regen. Nissan apparently never charge the battery to full capacity. May be that is why they said 80% option is not needed.

Also interesting is that at 0% dash indication, Leaf Spy still read about 9% power left. Looks like Nissan already designed the charging unit to prolong the battery life under normal use.

OR... the fudge factor was created because the BMS was simply not consistent enough.

My 2018 LEAF has had a relatively large range of "full" in the near 6 weeks I have had it including one time it charged to 506 GIDs, 39.3 kwh available and 99.51% SOC (this is real SOC...)

The real kicker is at 99.1 % SOC, I was able to regen 9 KW in E Pedal and that was low speed, no real slope regen...

Nissan has always done this, although it used to be about 95% actual SOC at 100% indicated SOC. The batteries still degraded. Let's hope that 91% actual SOC is low enough. If I get one of these Crap-Tastic cars I'll be stopping at roughly 80%.
