Batman:

do you know much about 40kwh Leafs

- batteries lifespan better than 24-30kwh?

- more reliable than 24-30kwh?

- does the X model have collision avoidance?

- is the X more efficient that G?

- after buying from Japan, how much SOH do you expect to drop when it "settles down"

how much did you pay for importing yourself?

I only know about some of these;

Some of the X model 40kwh cars do have ProPilot - if they have the button on the steering wheel, it's got it.

The G and the X are probably as about as efficient, I'm guessing the G might be a little heavier due to airbags.

I expect the SOH to be around 95% when it first gets here but should drop to around 92% after a few months of regular use. 2% per annum after that seems about right according to Flip the fleet.

You can get an X V Selection specification model in Japan which is close to a G spec but without some features, that's what I got. All up I saved about $6k over what a locally sourced car would have cost me for the same model year/feature set.

dumb question -

if 3 LEAF cars have 85% SOH, one car has done 20,000 ks, 60,000ks and 100,000 ks

which one would you buy and why?

Batman:

question if someone knows

how is the efficiency of the 40kwh Leaf vs latest 24khw Leaf

Specs found here;- https://www.fleetnews.co.uk/electric-fleet/electric-car-and-van-data

2015-2017, 24kWh, Leaf, 17.2kWh/100km

2018-2021, 40kWh, Leaf, 16.8kWh/100km

40kWh Leaf is 50kg heavier and cd is slightly better (0.28 vs 0.29). Cars are basically the same platform including mostly the same glass house, so I would expect them to be very similar in energy consumption.

Note; Time isn't part of energy. A joule (J) is a unit of energy. A Watt is a joule per second (W=J/s), so a kW.h is a kJ.h/s. Part of kWh is time divided by time or more precisely, hours divided by seconds which becomes a unitless factor of 3600 (3600s/h). A 24kWh battery could be described as an 86.4mJ battery. Now energy is force times distance (J=N.m). So, energy consumption expressed as kWh/100km also contains distance divided by distance (1,000m/km). Energy consumption could be expressed as a force (Newtons). So a kWh/100km is kNmh/s/100km, so the factor becomes 36 to convert that to Newtons. 17.2kWh/100km becomes 619.2N. No more alphabet soup, no more ICE units hangover. Multiply the distance you want to travel by this energy consumption rate and out pops the energy required. 619.2 x 100km = 61.9mJ or about 72% of my 86.4mJ battery.

Depends on the year. Younger than 3 years probably the 60k. 20k with 85% SOH probably has had battery issues e.g. overheating or poor handling. Just my 2 cents.
Older than say 4-5 years the 20k as you would expect that SOH with normal use. But 60k would be ok too, however you would also look at service record, tires etc.

2017/18. Batteries. Low KS car have extremely low QCs extremely low L1/2, medium K car has 586 QC and hardly any (2) L1/2, high KS have even higher QCs 1000+ and lots of L1/2

If you're going to go to this level of detail, you ought to get your units right:

A mJ is a milli-Joule, or one thousandth of a Joule. If your car has a 86.4 mJ battery, you have a problem

A MJ is a mega-Joule, or one million Joules

Sane applies to mbps vs Mbps. For all those complaining in other threads that their 100 mbps UFB connection is slow, well you shouldn't be surprised if it really is a 100 mpbs connection - a tenth of a bit per second is not great

EVs enhanced have finally broken their silence and pushed back the 16 blade to at least march 2023.

They've also put up a new video showing off their new thermal management system the pack will have. Looks like it's a bit more work to install the thing than shoving a new pack in as it needs a radiator, heating element and pump installed in the engine bay.

Interesting update. I'd be keen to swap what's under my Leaf at some point and I'd expect a decent credit for a 2021 battery with (presumably) good SOH for something a bit more durable. It's the repeated fast charging I really want.

I'm 99% sure our 2018 leaf only has a 3.6kw onboard charger which is annoying me because I've just had a decent 40A wall charger installed.
Anyone seen/heard/experienced a way to upgrade the onboard charger to the larger 6.x kw version?

This looks really good. It won't be cheap and not worth it for many Leaf owner, but if you need more range on a 24kWh Leaf then this would be cheaper than buying a new car. If you do longer trips and fast charge multiple times this would also be a significant upgrade. You could take the 2015 Leaf I used to have, which would be 8 years old in 2023, pay for the 16-blade system and easily use the car for at least another 8 years (probably quite a few more useful years than that) and with double the original range.

Buying a new BYD Atto 3 would cost you ~$47k after rebate, upgrading the battery on an older Leaf would only cost maybe 1/3 of that? It isn't bad value IMO.

I reckon the ZE1 is the optimal price point for this. You still have a reasonably modern car with Android Auto and Apple Carplay that the other models don't have.

The OG Leafs will be getting near ten years old now, and have the feature seat and trim wear to match.

I wondered whether the EVs Enhanced system runs off the 12 v battery -- I presume it does. If so, it's going to be very important to keep your 12 v battery in good condition, and has some system that stops a charge if the battery goes flat.

Yours is the situation EVs Enhanced is hoping to have happen as it frees up a reasonably good SoH battery as a potential donor. We are unlikely to spend what looks like being $20K to upgrade our 2012 Leaf which is realistically only worth $5K with 90,000km and ~60% SoH battery. The only way we can justify that expenditure is to consider the 16 blade battery as a long term investment which could outlast our Leafs expected usable life and then be transplanted into another later model Leaf with a rooted battery when the 'wheels fall off' our 2012. The substantial modifications required might make that scenario unrealistic though.
