My LEAF is with Nissan in Brisbane being "cycled". Been watching on carwings. Seems to be very different from the 144km that was on it.. Pickup in a couple of days, fingers crossed. ZENA stands for zero emission natural alternative.. not my idea

Just turned on my LEAF after a full charge at work. First time a capacity bar has disappeared. Down to 11.
LEAF Spy stated AHr 55.69 SOH 84% Hx 81.04% 60,969km 38QCs 2419L2s
Sad day.

If it's any consolation, you're doing better than most owners here!

No, down to 145km now sadly

Does anyone have power bars (not capacity bars) that some and go? Every day I drive to work I have five bars of battery remaining (used 4 bars to get to work). But at the end of the day, it displays 4 bars. When driving home, the fifth bar lights up again about 1km from work. It is very flat, so I do not think it is regen (also in afternoon traffic, so not moving quickly). The only thing I can think of is either heat (absorbing from the road) or a flagging cell that has a low resting voltage and the BMS readjusts as it gets feed from the other batteries?

I don't think I've seen it myself. I think the GOM went up but not the bars when I drove downhill all the way from Katoomba back into town which was around half an hour all downhill. jcan might be able to confirm since he lives out that way.
Haven't heard from you for a while Les, how many kilometres have you driven so far? Lost another bar yet?

When I came downhill from Cameron Park, I noticed the GOM go up, but I didn't look at the bars. Don't know if they would have caught my eye if they had changed.

LEAF goes in next week for the 90k service. Still at 9 bars of capacity. It still gets about 95-100km to a 80% charge when using eco mode.

They can't really refuse a price since you will be out of warranty. I am guessing a new battery pack would currently be about $8,000. At least a new battery pack should have the new chemistry and would probably last longer. If the new batteries are more resistant to heat, does that mean they will be more tolerant to fast charging and charging to 100 % ?

Not that I am aware. Only the 30kwh pack has the new chemistry. The 2014 packs are tweaked for greater heat resistance, not internal resistance.

The 30KWh model is not compatible with the 24KWh model (different bms etc.) but yes, it accepts more power for longer periods of time and is expected to only drop to 90% in the same time a 24KWh will drop to 80%.
But the new 24KWh packs are more heat resistant than the original packs.

Hopefully there will be something available in the future that is better than the current pack when it comes tiime to replace the battery, but I guess by that time I would rather have a new EV with the latest technology.

I hope it's because Nissan doesn't want to cannibalize new sales and might allow the upgrade later on.

Is there anything "special" in the packs that would prevent an after-market substitute, such as proprietary signalling or data transfer between the pack and the car's systems? (you know, a bit like how printer manufacturers tie you to their replacement cartridges by chipping them).

You made me dreaming about Tesla Giga factory will have more than enough capacity and improvement in cell energy density to produce higher capacity battery pack (say, 70kWh) for other EVs with a supercharger to CHAdeMO connector (as the new CHAdeMO standard can support 100kW input) I know it is a dream

Nissan Engineers confirmed it is technically feasible to fit the 30kWh to 2013 LEAF as "the charging system, motor, controller, and suspension are all identical to the 2013 LEAF". But Nissan don't offer it because "each car would have to individually undergo homologation, an expensive and time consuming process that it felt would not be worth the effort for owners when added to the cost of the new battery pack." transportevolved.com/2015/10/19/first-drive-report-2016-euro-spec-nissan-leaf-like-the-old-leaf-but-with-more-range-if-you-pay/Given a 2011/12 LEAF can fit a 2013 LEAF battery with and adaptor, I would think technically our LEAFs can fit 30kWh batteries. Anyone have idea about what the "homologation, an expensive and time consuming process" may be?

they are implying that you it would count as an engine modification so you would need a blue slip. is all i can guess from that.

no by homologation they mean the process official importers go through to prove a car is safe to sell. Plus it is a European article so rules would be different for Oz.
Interesting information Jacky, its a pleasant surprise that the charging system is not specific to the battery, so it does open it to someone else making batteries available if it is commercially viable. Things like Prius batteries would be a good parallel since they have been around for 10+ years; are there aftermarket options for them?

When Lotus decided to sell the Elise in the USA, homologation cost US$50 million and took 16 months.

Anyone have idea about what the "homologation, an expensive and time consuming process" may be? What is meant by homologation? Automotive homologation is the process of certifying vehicles or a particular component in a vehicle that it has satisfied the requirements set by various statutory regulatory bodies. It is mandatory to get this approval to export automobile products or components. Found the above explanation of homologation. Hooefully we will have the choice of fitting an improved battery pack in the future. After all the only significant thing that has changed in the Leaf since 2011 is the battery, so if we could fit a 30kwh battery, we would virtually have a 2016 Leaf. I am encouraged to learn that it is technically possible to fit one.

When Lotus decided to sell the Elise in the USA, homologation cost US$50 million and took 16 months. But that was for a whole car. Would it cost that much to just do the battery pack or do they then have to start the whole process from the beginning like it was a new car? Since most of the car has been approved, hopefully it would be a lot cheaper to do a battery pack. Still I think as the Leaf ages and there is more and more demand for replacement battery packs, Nissan will offer something. Whatever we end up with, it will be better than our current battery packs.

Another bar bites the dust...41,903km, down to 10 bars now and struggling to do a 90km round trip. Now I know why I didn't make it back from the airport the other night I wonder if the bars will start disappearing faster now as there is more pressure on the remaining capacity?

I lost my first bar at 12,500 km. That's pretty early...may be suffering from high temperature charging at the office Charge Point??? I lost my second bar at 26,300 km. This is actually quite encouraging news as it give more certainty (assuming linear degradation) that a new/refurbished battery might be in my future under the battery warranty. I've ordered the OBD2 reader, so hope to be able to do some diagnostics to find out why the pack is degrading. When I move to Perth, I expect to increase usage to >60km per day as my wife will be using the car to take the kids back and forth to school each day and we will be taking trips down to Margaret River on some weekends. I've noticed it is getting harder to use the 80% charge timer feature as we do need the reserve power frequently to allow for side trips off the regular commutes. Is anyone aware of a lost second bar earlier than 26,300km in Australia? Attachments:

Turned on the LEAF today after not using it yesterday and a full charge the night before to discover its second capacity bar had disappeared. Down to 10 bars.

Looks like you're doing well if you lost your second bar at 74k. I remember overreacting slightly when I lost my first bar. By the time I lost my second I glanced at the dashboard and thought, "Hmm, would you look at that". Then drove on like it was nothing. I'm currently at 75% SOH after 64k.
I wonder if Nissan's EV strategy is languishing because they're spending so much on warranty replacements overseas and can't make a business case for it?
