Is your 30kWh Leaf really 30kWh?

jprboy

Do you have a 30kWh Leaf?

If so are you sure it really is 30kWh?

It appears that some 2016 Leafs were sold as 30kWh but were actually only 24 kWh.

See thread here:

Get checking !

I would have to question if buying a 16 car and paying the extra for 30kWh you dont notice it can only do the range of a 24kWh.....with all the details of range etc and people been obsessed with range on electric cars

If you upgraded from a 24kWh to a 30kWh you would surely notice.

However, if your first EV is a 30kWh you've no frame of reference and some people are not as consumed by mpg/range etc as others.

I've often asked friends and colleagues over the years what mpg they're getting in their ICE cars and the vast majority haven't an iota.

First of all before people start panicking that they may have a 24 Kwh leaf instead of 30 Kwh , will you please get Leafspy and a OBD II to Bluetooth dongle and see if it matches closely the picture below.


Bat Sts AHr is what you're looking for. It should be close to 75 on a new healthy 30 Kwh pack.

Making a comparison to petrol/diesel car now is not really relavant. Most people dont know because they dont worry about it

Electric cars are restricted by the distance they can travel, so people who purchase are aware of distance, hence why you but 30kW instead of 24kW.....you dont buy a 1.2 instead of a 1.1 for more distance do you?

Trying to talk yourself into a situation in the hope you get a free car is ludicrous

Fair enough on LeafSpy, Mad Lad, but here's a quicker, easier and FREE way of checking:

In 2016 and 2017 the Nissan plant in England built LEAF with both 24kWh and 30kWh battery packs. The late production 24kWh LEAF is nearly identical to a 30kWh.

The easiest way to tell them apart is to check the weight plate in the driver's side door pillar. The 30kWh is heavier with rating of 1970kg. If the weight is 1945kg, the car is a 24kWh.

Not sure why we need 2 threads running on this as it is already discussed in other thread?

That's fine provided the correct details are on the labels..........

The title of the other thread doesn't reflect the core issue in a clear manner but I've already suggested that it be edited accordingly.

I believe with the car in question, even the weight plate was a 30kwh weight, so while it would normally be the way to tell them apart in this case the weight plate was also correct for the 'sold' spec, but not the actual spec, so as MadLad said, Leaf spy looks to be the way to go.

I checked my leaf spy and the Ahr is 83, so I'm safe with my 30kwh Leaf:)

83 Ah haha, nice, 75 is probably the Nominal AH.

If you multiply 75 x 364 volts as in the above pic you get 27 Kwh.

84 x 364 = 30.5 Kwh which could also be correct as it's a 30 Kwh pack however even though the BMS hides/restricts some Kwh it's not hiding the voltage just what it tells you via the SOC % on the dash.

Please give voltage + AH reading with your next 100% charge and we can see what the resulting Kwh is.

That is what it was the one and only time I could get the dongle to work (not long after I got the car). See pic. I don't know if the low battery % left at the time influenced it or not. Your volts say 364, mine say 346. Don't know why they are different or if it's normal for them to be different but multiplying them like in your example gives close enough to 28kwh

That's 28 Kwh.

Interesting to see the voltage and Ah difference between the two pics !

Pic I posted had lower AH and higher voltage, yours has lower voltage higher Ah.

How many Kms have you on it now ?

Just over 22000km. Would love to know what the SOH is, but I need to buy a new dongle.

As per the thread you referenced in the OP, that didn't confirm it.

The range and LeafSpy reports are the only ways to actually tell for sure.

It seems Nissan's inventory control is a bit lax and they stuck the wrong battery into the car. A ridiculous mistake to make and still manage to get passed delivery inspection etc.

Do they actually weigh the car? Might the wrong sticker not be applied if they think it’s a 30kwh? Surly the range is the give away

So the 24kWh battery can be swapped out for a 30kWh? I had heard they were not compatible.

Not confirmed in this case. But as the battery is the same physical format as the 24kw/h and Nissan need to keep an inventory of spares for warranty replacements it's highly unlikely they're keeping stocks of both. My guess is the 24, 30 and 40kw/h batteries are all interchangeable as long as the onboard software is adjusted accordingly. Nissan don't want to sell you a battery upgrade of course... they want to sell you a whole new car.

It could make sense that you can swap a 24kWh battery for the 30kWh, it's less powerful so may feel like a battery that's degraded to 80% by the car.

24 and 30 Kwh are not compatible. Can't be put in either car.

Im sure Nissan could if they wanted to.

Its clearly not just a direct swap. The ECU's etc would have to be flashed so probably beyond even the battery indy's that exist but I bet Nissan could do it if they wanted to.


Unless the physical dimensions of the pack are different and can't physically fit?

Yes they're physically different dimensions. Even the 24 Kwh 2011 has to have a current gen 24 Kwh modified in order to fit but don't think it's anything major.

I din't know how different the 30 Kwh is though.

But while the physical exterior pack dimensions of the new 30 kWh LEAF battery packs are identical to the battery packs found in every LEAF that has rolled off the production line since late 2010, internal differences in the way the packs are wired and connected to the car means that a 30 kWh upgrade path for existing cars isn’t possible.

They sure as hell didn't go out of their way to make it compatible.
