Airflow improvement for Leaf
I found this post @www.mynissanleaf.com and its very useful to Sri Lankan Leafers. In this post he mention 30C is the optimal working temperature. But 30C is way too hot for a Leaf pack. It might be Optimal for providing power. I saw some Leafers laminating under carpets in Sri Lanka.
++++++++++++++++++++++++++
Heating up and cooling down happens at the same rate if everything else stays the same. If heat is locked in a pocket below the vehicle (heat rises cold falls down) that may change things.
For those who have garages can use regular fan just to circulate air better under the belly. Weak 20-50W fan is all that is needed. Hardest part is to get air moving in the gap between battery and car. Also cooling down interior should help (open window).
30C is the optimal working temperature for battery. Pretty much ideal for hardcore usage. But 40C is the upper edge for Optimal working temperature, ok for use but not for rapidcharge. 30C is upper edge for storage. Nothing bad in 8hours of storage at 30C. 35C is above Optimal storage and 40C is upper edge.
PS! have an idea. I believe battery service plug cover is a direct access to that air gap between car and battery.
I believe that just removing carpet and metal cover will allow MASSIVE airflow improvement.
I ask somebody to do some measurements with hot battery (no need for hot weather)
If it works then it will drastically speed up battery heat dissipation.
It is even possible to push cold AC air from cabin onto the battery upper part if vehicle is stationary and air re-circulation is disabled. Tight space between car and battery is ideal for uniform distribution of airflow (stationary).
It is safe only if there are no children inside the vehicle. But for adults it is absolutely safe. Just don't remove the fuse.
Depending on airflow this might have to be closed when driving on highway.
If this is the case I guarantee a massive change in battery cool-down period while stationary (or heatup for nordic users): stationary in garage, windows ajar, heat rises by itself.

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.

EV Fast Charging Centers in Sri Lanka
Fast Charging Locations - Please update/add locations.. Special thanx to Ashoka @ http://green-frontiers.net/locations.html
1. Borella - #57, Cotta Road Colombo 08. SparkEV +94 11 7 590 590
2. Galle Dadella (opposite Jet Wing Light House) SparkEV +94 11 7 590 590
3. Godagama 0718100100 , 0712768698;
4. Maradana Trace Expert City, Maradana by chargeNET +94-1-5551-551
5. Battaramulla Green Frontiers +94 112884738 , 071 071 0271
From Battaramulla Town, turn to Udumulla Road. (along Battaramulla - Malambe Road, near Sathosa and Singer)
Drive exactly 400m along Udumulla Road. It is to your right.
6. Panawanna(near Kahawatta), Palmadulla -Opening Date : Friday 11th December, 2015 by Green Frontiers
Channa : 077 2384286, Cyril : 071 4747847, Green Frontiers 011 2884738
7. Kurunegala - Green Frontiers 071 844 7472 , 0372056224
Kurunagala location is also close to the town and again free from city traffic. There are shortcuts drivers can use to reach the charging point avoiding city centre congestion.
Located in the Kurunagala - Kandy road, this provides the added benefit of somewhat solving the problem for drivers to Kandy. From Battaramulla to Kandy via regular road is just 122km but one has to surmount Kadugannawa hills, making it risky to attempting Kandy in a single charge. However, the nice route via Kurunagala offers a less congested road, less steep hills and the nice option of having a fast charging station, in case you need it!
8. Galle - Aradhana Filling Station 071 071 0271 - Green Frontiers (Highway Entrance Road Nugaduwa, Galle )
It's on the exit/entrance of Southern Highway, Pinnaduwa. Just about 300 meters from Devata. This means people who enter the highway, exit from the highway, people who use the old Galle Road or anyone who is driving around Galle has easy access to this spacious and well known business premises in Galle. Also, the location is quite and free from city traffic.

Government decides against increasing duty on EV's
Source : http://bizenglish.adaderana.lk/government-decides-against-increasing-duty-on-electric-cars/
At a recent Cabinet meeting the President has decided to cancel the 2016 budgetary proposal to increase the duty on electric cars from the existing 5 per cent to 50 per cent.
Joint Cabinet spokesman and minister Gayantha Karunatilleke said that decision had been taken while considering the requests from various parties.
Ada Derana Biz also inquired from Sri Lanka Motor Vehicle Importer’s Association co-president Mr. Kokila Deekiriwewa on the increase of duties on electric motorcars from 5% to 50%. He responded by saying, “At the Cabinet meeting last week, the President had put forward a proposal to remove the 50 per cent duty imposed on electric motorcars through the 2016 budget. If this proposal is to be implemented, then it needs the approval of the Finance Minister.
“If such a tax revision is being done, under Sub-Section 3C in the provisions under the Manufacturing Special Tax Act, the Finance Minister has to inform the Customs Department. Only the Finance Minister has the authority to sign this. To my knowledge, the Finance Minister is overseas at present. Hence, we have learned that such a notice has still not been given.”
