Gimme More

Posted: June 11, 2013 in Nissan Leaf Diary

So the other week I passed the 40000 km mark, (I’m over 41k now).

After reaching 40000 km

I’m glad to say that I have had no real issues with the only exceptions, a few broken CPs and also the more frequent and more annoying CPs blocked by ICE cars. Of course, Leo Varadkar could do something about the latter but as yet still seems to not care at all. Obviously after having such a good experience of having the Leaf, I want more (hence the title). Not just more mileage but more CPs, data, updates etc. Luckily enough I have been getting my wish, recently the CP in St Agnes Road, Crumlin (which I have long complained about) was changed out and is up and running. I’m delighted about this as I can use it when I have my boy and need to pick up from or drop off to school (and I suppose it only took 1 & 1/2 years to get replaced :p)  More importantly the CP outside the ESB building in Portlaoise is up. I’m a bit peeved at being told it would be up some weeks ago then being ignored every time I sent an email asking for an update on why it was not (finally got a reply to say it was running last thursday) but am genuinely delighted with it being there. It is a great location, close enough to the shops and also it is a location that would generally never get ICE’d except on exceptional occasions. There has also been a number of other CPs popping up (standard & fast) which is making it easier to get around. In fact, in Northern Ireland they are going up at a fantastic rate, only a little while ago there was a few, no there are loads (as can bee seen on this map). Also I wanted more data so about a month ago I bought a bluetooth ODBII connector (model ELM 327). It can be bought for about 20 euro on eBay or other online retailers.

You simply plug this little baby in and download an app from this call Leaf Battery. Once you have paired the 2 up the information on the batteries is amazing. It will tell you the state of charge, battery temps, battery voltages, kWh amount, Wh used during journey as well as expected DTE (distance to empty). DTE depends on you setting your average kms per kWh. Plus much more info.

So what have I found out. Well a few things.

SOC depends on the heat: @5°C 93.0 SOC, @8°C 93.8 SOC, @12°C 95.5 SOC, @15°C 96 SOC.

The highest kWh I have noticed on my Leaf is 23.3kWh after a charge, I guess this is relative to the temperature/SOC.

These are the averages of SOC vs bar disappearance (i.e whats left on battery as the 12 battery charge bars disappear)

Bars lost / SOC %

1 / 87.2%, 2 / 80.9%, 3 / 75.4%, 4 / 68.8%, 5 / 62.7%, 6 / 56.5%, 7 / 50.4%, 8 / 44.8%, 9 / 38.9%, 10 / 33.5%, 11 / ?%, 12 / ?%

All numbers are rounded down. Also there was less data points to work with after 8 bars as I often have 3 bars left whether I am travelling up or down. This is why there is none for 11 or 12. I did once get the car to go to – – – on the dash but didnt have my phone with me. When I got home I went back out to the car and check the remaining SOC, it showed 14%. I am not sure if this is because Nissan leave a certain amount of reserve (there last software update increased this) for you to get to a CP when the dashs appear. I believe there is about 5 mile left after the dashs but don’t quote me on that. I will do some more research and try and find the remaining numbers to have a complete set, including the important – – – / SOC% number and also what is left when it goes into turtle mode (although this will mean purposefully running out of power).  Anyway, for those who like even more data, here are copies of some logs the app stores on the phone. They can be opened in Excel as a csv files. No data has been changed with the exception of the GPS locations removed. BatLog2 BatLog1

Finally, the last more, I have been informed at the end of July the new Nissan Leaf will be coming out. Increased range, better safety (with the 4-way view while reversing), more luggage space, faster charging, heated seats & steering wheel. I am already looking at how I can get my hands on this model by trade-in or sale etc… (but thats just because I’m greedy I guess :p  )
