Just seen this YouTube video regarding recent experience in charging a 40 kWh Leaf at high battery temp. Seemingly there is reduced throttling of the charge rate...


Have owners on this forum had software updates and had better charging performance?

Also look how cold it is. The software probably knows that heatbisnt rising as expected it as fast so it can keep the higher charge levels..

Probably something to do with it. Since the climate control compares the set temperature with the outside temperature, rather than the actual cabin temperature, so keeps on heating, maybe the charge throttling is based on outside temperature as well :)

Maybe the Leafs built since the right hand drive pause do actually have a new floorpan as i was told ready for the 60 battery and as such their 40 packs are reconfigured with more air space.

Unsure, I would assume a quiet software update. Especially considering the vechicles in these videos are LHD?

No there was a production stop of RHD earlier this year to concentrate on LHD only,i was told at this time a new floorpan was introduced going forward for all Leafs ready to accept a 60 pack when its ready,so maybe the new floorpan has something to do with it,Insideevs state its only found on cars after Nov build so far.I cant see how they can change software and just let the packs charge too hot due to degradation issues later on.Hopefully info will confirm it either way soon.

Oh right. I didn’t realise there was a new floor plan on newer vehicles... makes my decision to go for a leaf in the next month harder. Does the new lessened rapidgate fix make it worth the extra £2000-3000 to buy new...?!

I was told about the floorpan by my dealers EV specialist,i would like to hear confirmation from another source to ensure its genuine but its obviously very plausable.

My questions about this fix would be.

A is there indeed a new floorpan/battery config on newer cars.?

B the 60 is supposedly getting active air cooling,the 40s price has gone up so is there an air cooling system on new builds?

Oh right, interesting to see if this is true.

The videos seem to show no change in temperature increase due to charging, but just an adjustment in the limits. To me, this implies no active cooling.

Let’s hope for some confirmation!:)

Interesting that he mentions it’s too old to have it. Unsure if this means it can’t have it or it just hasn’t been updated yet!

So it all comes down to this…

1. We know the 2019 Leaf E+ will come with a 64kWh battery with "active thermal management" (albeit forced air cooling only)

2. Nissan will offer in 2019 both a '40kWh' and '60kWh' Leaf just like in the rest of the world (but not the UK) there will be a 39kWh & 64kWh Kona/e-Niro.

So does this mean that Nissan (to compete with the Koreans globally) has altered the 2019 40kWh Leaf battery enclosure to use enable the extra flow of air (possibly forced in 2019 models but unlikely, just passive flow as currently with the 2018 model) but with more 'space' to enable better passive cooling? So they can change the charging software parameters to allow for greater battery heating to occur knowing that on commencing driving the increased movement of air will allow greater cooling on the 40kWh model?

Or will it just be a software change and no hardware revision for the 40, simply based on data gained over the last year or so? (This is my bet)

Can't wait for the E+ reveal with greater details arising and what it means for the 2019 model of the 40, will it get LG batteries & will it get active cooling.

(New years resolution I'm going to stop using the phrase thermal management in regards the LEAF because that implies heating as well as cooling.)

Cars get revised all the time Its totally normal,im going with a redesign of the battery for 2019 cars more in line with the 60 pack.

Nissan have sold loads of the 40s, they wont want to modify all those cars,anyway they claim there is nothing wrong with them and its normal behaviour.

Now all they have to say is we have improved the design for 2019 models and it behaves differently to the 2018.

So lets remember the vast majority of 40 owners have been banging on about how its not an issue for them so i dont see a backlash anyway.They are obviously very happy with their cars and the new car will probably attract even more buyers now than it would have done.

If this is the true situation it points to physical changes rather than just software upgrades. This might explain in part why the car availability became so delayed if there was a stop on manufacture. We do know shortage was caused by output being dominated by LHD builds for Norway before the grants in Norway changed. Handy that battery overheating is not a huge problem in Norway for most of the year.
