Temporary electrical grounding of Nissan Leaf charger using Yakada inna
This post shows the temporary earthing of Nissan Leaf EVSE. I am sharing of real life
experience. Some rural areas in Sri Lanka do not have proper earting systems & 15A outlet.
Recently visit my friends place @Hettipola & face this issue. No earting & 15A outlet.
This is not a correct way, but in an emmergency this is OK.

Nissan Leaf Long life mode setting... 80% charge
Cooler climates users charge regularly to 100% and others have tried to stick to 80%.
Temperature seems to be the largest factor.
Zero Emissions button --> Settings --> Long Life Mode (80% charge) --> ON
Tips:
* Don't do multiple quick-charges in a short amount of time.
* Try to garage or shade it when parked
* Charge to 80% when you don't need the car for a long tip
* Don't charge if there are more than six in battery temp bars or lower than two
* Lifting your foot off the accelerator rather than hitting the brakes.
Also you can set the charge timer (if you wish) by pressing the blue “e” Zero Emission button to the lower left of the navigation screen. This will bring up your
selection menu. You can select a 100% charge, or an 80% charge. You can set the charge to start and/or stop at any time you wish.
I am charging to 100% every time. Most people feel that stopping at 80%, so I wouldn't and don't worry about that.
Driving and charging habits from http://livingleaf.info/2012/07/care-and ... f-battery/
NISSAN recommends you use the following driving and charging habits, where possible, to help maximize the battery’s useful life:
* Avoid exposing a vehicle to ambient temperatures above 120°F (49°C) for over 24 hours.
* Avoid storing a vehicle in temperatures below −13°F (−25°C) for over 7 days.
* Avoid leaving your vehicle for over 14 days where the Li-ion battery available charge gauge reaches a zero or near zero (state of charge).
* Allow the vehicle and Li-ion battery to cool down after use before charging.
* Park/store your vehicle in cool locations out of direct sunlight and away from heat sources.
* Avoid sustained high battery temperatures (caused, for example, by exposure to very high ambient temperatures or extending highway driving with multiple quick
charges).
* Use the normal charging or trickle charging methods to charge the Li-ion battery and minimize the use of public Fast Charge or Quick Charger.
* Avoid sustained high battery state of charge (caused, for example, by frequently charging to 100% state of charge and/or leaving the battery above 80% state of
charge for long periods of time).
* Allow the battery charge to be below at least 80% before charging.
Moderate driving.
* Use of ECO mode.
* NISSAN recommends charging the batteries using the long life mode unless the vehicle is going to be driven a long distance. See “Charging timer” in the “CH. Charging”section.
* If the vehicle will not be used for an extended period of time, charge the Li-ion battery using the long life mode once every 3 months. Do not operate the charging timer repeatedly while the charge connector is connected to the vehicle after the Li-ion battery charging is completed. Doing so may discharge the 12-volt battery. The power of the Li-ion battery can be checked on the Li-ion battery available charge gauge. See “Li-ion battery available charge gauge” in the “2. Instruments and controls” for details.

How to modify upgrade Repair Nissan Leaf Charging Cable....
Source : http://www.evsrilanka.com/viewtopic.php
One day morning my brother came and show me his New Nissan leaf cannot charge No lights when plug in to power
I just observe and spot diagnosed this should be a problem of power supply (step down transformer) then I opened it and found primary winding (AC side open circuit) I decide to replace the Power transformer.
I just try to open the Charging controller all the nails are covered by long plastic knobs you need to remove those 6 knobs to access the nails
you can make small drill hole and put the needle nose flier and pull it then you can see the nail.
To remove nail you need Allen key set then remove all six nails and remove the cover make sure you place the silicon beading which used to prevent water entering into the controller do not damage twist during re assembling
This is how it looks like
Identify the parts remove two nails on transformer block using plus screw driver
I found transformer primary side is open and give infinite resistance my diagnosis is correct so I proceed the repair replacing the step down transformer.
[flash=]I came to know some people charge nearly 20,000/= Rs for this repair or Upgrade to 240V as both use the same procedure I decided to write this article prevent this racket do not pay more than 2000/= if have no skills to do this job contact me I will help you. [/flash]
Disconnect the two connectors Yellow and Red and check with ohm meter for connectivity if faulty AC side Red wires give infinite resistance so it is time to replace the transformer you can not find the same model but we can find same or better specifications
Panasonic use 200V primary and 19v secondary we can find locally 240V 9v X 9V that is half wave 18V that is enough for the work you need to choose at least 500ma transformer you can find this very easily in open market. see the picture bellow.
secondary side center wire is not used in this project cut short and insulate
Cut both connectors close to old black transformer and solder to new transformer red wires to Primary side and yellow wires to secondary side. if you have heat shrinkable tube insert it to the four ends of the wires before soldering and push away from your soldering area to prevent shrink those during solder.
you may find it difficult to fix due to plastics you may remove disturbing plastic notches to accommodate new transformer screw the two nails and fix the transformer connect the connectors to correct place.
assemble it and power up enjoy you have saved over 100000/ rupees with less than 1000/= rupees any comments or suggestions are welcome
