LEAF owner here. It's nonsense to suggest that when you get home from work in your LEAF you should not plug in in to charge. Anything up to an hour's driving does not make the battery excessively hot, and the 7kW charger installed at home does not create enough heat to be a problem either. If you really want to delay charging, the LEAF has a timer so you can start charging at midnight, for example, and have the car fully charged by the time you start in the morning (and maybe benefit from cheaper electricity too, on some tariffs). The real problem is longer road trips requiring rapid charging several times. Then the battery does get hot. In my experience the battery temperature rises most rapidly during rapid charging, and more slowly while driving. On the older series 1 30kWh LEAF it can overheat badly; my 40kWh LEAF 2.0 throttles charging rate to mitigate the problem but that mean longer waits. It's not a car for frequent road trips in a hurry, but it's absolutely fine for doing up to 120 miles per day.

@ritz56063 жыл бұрын
Instead of calling it a flaw, you can look at the Leaf as a car that has developed an alternative cooling of batteries, not only by air but also within it's chemistry with low degradation. If googling for problems with cooling systems in EVs, you find that problems occur rather often with active liquid cooling systems as well. The limitation with hard driving and fast charging is well known, and it's not a big issue. That said, I wouldn't recommend the car if you live in hot areas and plan for long drives without pauses though.

Approximately 6K a month and around 200km a day. I charge multiple times a day with fast charger. I bought it for 22K euros in 2022 and it is 2018 model with 40kw battery pack. I have saved almost 20K fuel price which is equal to its purchasing price. It is an excellent deal if you drive more than 100 km a day. My battery is still perfect, and soon I am going to touch 200K km.

@@SamAlexanderKZbin What you must consider is that the car was developed to a certain price point and basically designed as a town car (based on research around average daily miles). It is my understanding that active battery cooling was not originally included, for simplicity and to keep the price down. As one of the first EV's out there, the Leaf was really a test bed for the issue of battery degradation and other manufacturers have designed in active cooling. Rather than a cynical attempt to shorten the design life of the car, the issue is that active cooling cannot be fitted. The body shell would need a substantial redesign at a vast cost, to include active battery cooling and the new leaf is basically the same body as the old one. The company really had no choice but to include larger batteries in the face of the competition, while it was still unable to develop active cooling. They did work on the battery chemistry to make it more heat resistant. I think that it really depends upon where you run the car and how you use it. If its used mainly in the city in a temperate climate and not rapid charged frequently, then there is no reason why the battery should not degrade rapidly.

Luckily, Nissan was still offering battery replacement at the time, and after a few long and lengthy calls with Nissan, I was given a discount to replace the battery for half the cost. Can't imagine having to pay $5k after 7 years. Since then the Leaf is our second car that gets driven once every few weeks. I can understand how the first generation Nissan Leaf only has air cooling, but the later generation of Leaf not having liquid cooling is very suspicious, as they would had received numerous complaints about their battery degradation issues by then.

New LEAF owner here. We purchased a 2017 LEAF off lease out of coastal CA , 30kw, 12 bars in April, 2020. After the state EV vehicle rebate our net cost was ~$9500. After nine months and 3500 miles I'd rate this as the best used car we have ever purchased. For in-town commutes it is the perfect vehicle. Sure, better battery management would be nice but not essential as long as you take reasonable care. Don't use fast chargers too often (or ever) & don't charge a hot battery. This vehicle is designed for shortish commutes not long distance trips (and the cost reflects this). When purchasing a used vehicle try to get one off lease from a relatively cool area of the country such as a coastal climate. I don't know about the newer LEAFs but I would not hesitate recommending a 2016-2017 30kw used LEAF even to a family member.

I tried fighting Nissan for years to no prevail. Secondly a cell short-circut in the battery pack, will brick the car. In more modern battery packs, from other manufactured a cell short-circut will just cause the pack to isolate the shorted cell. Nissan quoted me USD 6000,- to change 1 cell in my leafs pack.

So, I'm stuck with a Leaf with 50 miles range. The only solution i see if eventually buying a solid state battery for the car, one that won't require a thermal management system and will give my 2011 Leaf a range around 300 miles. Given Nissans handling of this whole battery system i would advice everyone to steer clear of any Nissan product, electric and ICE.

I had a 2011 Nissan Leaf I bought used and it got down to 40 miles of usable range. I was not happy. But I also realized that I had bought a car that had been leased by someone who lived in a very hot part of Southern California and who apparently did most of their charging with DC fast charging, not plugging it in at home. I am purchasing a 2018 Nissan leaf, and yes it still does not have active thermal management, but the battery chemistry has been reformulated three times since 2011, and the software that caused “rapid gate” has been upgraded. Most of my driving and charging will be done with my level two charger at home. I would also point out that in colder places, northern latitudes in Europe, North America, and Asia, there are 10 year old Nissan Leafs that have experienced virtually no battery degradation at all. Since the car is designed in Japan, perhaps the engineers just don’t get it about the way the rest of the world drives, or how hot it is in the rest of the world. The new Nissan Arica will have an active thermal management system in its battery. There are a lot of variables with this issue, so to posture it is this absolute flaw that will affect every leaf and every leaf owner is a bit of an exaggeration. I would refer all of you to transport evolved show on their own Nissan leaf in Portland Oregon, and it’s 10 years of service with no battery degradation.

I live in Northern Europe and there are no known issues with Leaf battery degradation. There are numerous Leaf (Gen 1) used as taxis covering over 150,000 miles (not km) before the batteries are replaced. Indeed, there is very little demand for battery replacement simply because there is no need. My 2015 24kwh Leaf has done 55k miles and still show 12 bars, and I can get 90+ miles per charge. The secret? Do not let it run down below 20% SOC and charge up to only 80 - 90% SOC unless you need the extra charge.
@loungelizard8364 жыл бұрын
It's definitely intentional. In California, 2011-2013 leafs with less than 40,000 miles can often have less than HALF the battery capacity. My 2012 has only 35 miles (4 bars out of 13) range left after only 42,000 miles. Nissan is too smart to NOT KNOW that what they are doing is bad for customers! The cost of a liquid cooling system is only about $50 more per car, far less when amortized over THOUSANDS of cars. Yet they won't put in liquid cooling? They aren't stupid, they know they have to LOOK like they are promoting EVs while simultaneously making EV's look like garbage and supporting their dealer networks!

Nissan Leaf owner here. If I got 50% of the original miles I would be VERY happy. Presently (No joke) I get 30 miles per charge and have 50,000 miles on the car. Nissan LIED top to bottom. Cost to replace the battery? $9999.99 (but not $10,000...). Nissan claims that the 30 miles per charge that I get at 50,000 miles is equal to the 70-80% they CLAIM I would get at 100,000 miles. Ohh by the way, you do not get a NEW battery for the $10,000. You get a USED "RECONDITIONED Battery. We were trying to decide which was the worst car ever produced: The Leaf or the Yugo. We decided the Leaf as the Yugo got about 80,000 miles before you junked it, and this will not get 60,000. As for the making outrageous amount on small servicing I was charge TWICE the high amount for the first servicing (adjustments only) even though I provided a coupon from Nissan for a "Free First Servicing". I will never buy a car from them again. If you think I am kidding feel free to provide a way to get in touch with you, and I will, and verify everything. This car is a RIPOFF as you have to divide the price by the miles you get to find out how much it costs to drive per mile. It is also NOT environmental, as Electric cars are worst for the Environment until they hit 60,000 miles, and this one will be junked before then. I am looking at Chevy Bolts (with active battery cooling) already. FYI I live on the coast, usually charged 110V and occasionally charged 220 (once a month).

Even though the LEAF cannot do extremely long road trips, think about the utility it does offer. With its 200 mile range for the LEAF Plus, charging every night. If you never used public charging and drove just as far as you could based on your home charging range, you could drive 73,000 miles/year. That's 200 miles times 365 charging each night. Most people do 12-15k miles, so about a fifth of that number. The LEAF can still do loooooooads of miles for people at a quite affordable price point when you get one on sale, which is happening right now worldwide.

I don't know that the "critical flaw" you're discussing - which isn't secret nor unknown about the product - is actually a flaw. When they released the 62kwh battery, they reconfigured the battery pack to have 3 cells per "unit" and that drastically reduced the heat dissipation while fast charging (heat has never been a problem with level 2 home charging). It actually doesn't even have a fan, the Leaf is 100% passively cooled. I don't know that the situation is as bad as some of the claims in your video, however I'm aware there are some customers that have had premature battery problems. But I don't think its the majority of Leaf vehicles sold, I do know a 2018 40kwh Leaf owner and it has lost less than 10% over the last 4 years, that's with fast charging occurring. I do think car companies in general, partially because of the economic paradigm we live in, like building 'disposable' products rather than fixable ones. The same is true of a Tesla, they offer battery replacements, but they are prohibitively expensive and not worth it. We need more 3rd party, aftermarket battery servicing for EVs to make them last because the EV motors and other parts are lasting much longer than ICE cars.

Because it has no liquid cooling, you can't fast-charge the battery without causing damage to the battery. So that car is pretty much limited to the slow 240V home-charging that most people will be giving it, and the Leaf is not a car you want to use on long road trips where you have to charge it while you are on a trip. Also: DO NOT top-up charge the battery as that will kill the battery quickly. Only charge it after it drops down to below half-full.

If you have the 62kwh version then not fully charging it is reasonable, but if you have the 24kwh version, you're essentially throwing away driving range that is at a HUGE premium 80% charge on the 24kwh model only gives you about 120km total On the 62kwh version you would have around 250km total at 80% charge

I've owned and driven LEAFs from 2011 through this summer (a 2011, a 2012, a 2016 and a 2018), and it's my impression that there is NO cooling *whatsoever* . Heat escapes from the cells by conduction through the battery pack case. I remember driving from Portland to Bellingham one winter where the ambient temperature was around freezing, and I watched, enraged, as the battery temperature gauge rose to just below the "red zone" with successive DC quick charges. I still can't feature how, with upwards of 60 degrees F of temperature differential pushing it, the battery heat still couldn't escape.

Overheating during charging could be mitigated by Nissan allowing the owner to throttle the charging speed manually You shouldn't charge a battery at more than 0.7C, MAYBE 1C if the battery is cool In the case of the 24kwh battery, charging it at 50kw is suicide, and you shouldn't have to drive across town to find a 20kw DC fast charger so you dont wreck the battery
