Watch How One Driver Controls Nissan LEAF Battery Temps On 376-Mile Trip


A Nissan Leaf owner documents charge speeds and battery temperatures on his drive from Scotland to the Milton Keynes for Fully Charged Live.

James of the YouTube channel Lemon-Tea Leaf recently put his Nissan Leaf to the test on a nearly 400 mile (643 km) trip from Scotland to Milton Keynes. His goal was to attend Fully Charged Live. While he has made similar journeys before, he uses this video to show how he minimizes heat and reduces trip times.

Nissan Leaf battery temperatures

A route was planned with charging locations placed about 70 miles apart. In order to keep battery temperatures down, James kept his speeds between 80-100 km / hour (49-62 mph). He chose this max speed after Nissan informed him that 62 mph is the national speed limits for highways in Japan.

His hope was that keeping with these strategies will keep battery temperatures down and charging speeds up. In the end, he was able to improve his car’s charge performance over his previous attempt at the same trip.

Keeping Charging Temps Down in Nissan Leaf

James provides battery temperatures before and after each charging session. The current state of charge and temperatures while driving are also provided during the drive.

If you already own or are interested in a Leaf, the video is a good watch for the amount of data presented. Check it out below:

On this trip to the Fully Charged Live Show how I kept the temperature down before hitting #rapidgate in the Nisan Leaf 2018 on my nonstop (except for charging) from Scotland to Milton Keynes. I had a chat with Nissan Customer Support.

“from Scotland to the UK.” Was there another referendum that I missed?


James has excellent tips and charging strategies l, on his Lemon-Tea Leaf YT Channel, to counter any 2018 Leaf #rapidgate battery overheating concerns.

Just be prepared to spend a little extra time out on the road, by keeping driving speeds a little below 60 mph, and your DC fastcharge tapering won’t be quite so significant with his well implemented technique.


Don’t be an apologist for your favorite BEV like bro1999.

The Gen2 Leaf is gimped bottomline. It’ll always taper after one DCFC session. The video proofs you can’t avoid it even if you drove like grandpa on our US freeways and eat followed by a poop at every charge stop.

I’m still getting one. My plan is to use it for what’s it’s good at – being a city commuter. In CA, even with a good DCFC network, I won’t recommend it for long trips. The Bolt is a better choice if a CCS network is available. At this price point, the base TM3 (if it ever shows up) is the best choice.

There’s another article today here on IEV that attest to the same thing. A charging network is critical to BEV success. If it is not readily available (sorry 1-2 plugs is only for the brave) or gimped (rapid charge taper), then the driving experience will be terrible for most.


Battery University says charging temps should be 32 to 113 F, discharge temps -4 to 140 F.*

*’common’ rechargeable batteries

/BU-410: Charging at High and Low Temperatures
//Without a thermal management system — shouldn’t the Leaf’s driver display show a detailed temperature display (perhaps including predictive (trend) information) , and some guidance in the owner’s manual?

///slow down to 49-62 mph on a Texas highway and see what happens — you’ll be in for a real adventure


It is quite easy, in the 2018 Leaf, to get into the low 120*s F on the second DC FC, especially when summer driving temperatures get above 90*F out on the highway/freeway. It really starts to slow down charging speeds below 1/2 the normal 40-45 kW charging speed.

So most summer trips over 300-350 miles, in higher ambient heat, can start start to add a bit more “CHAdeMo TIME”.

Only LeafSpy Pro really gives you the pertinent information, to keep your charging around or above 30kW, when getting into your second and third consecutive road trip DC FC.

Texas Leaf
It doesn’t sound like you have not ever driven an EV in Texas, much less driven a 2018 Leaf. There are still so few CHAdeMO charging stations in Texas and surrounding state that going cross country from CHAdeMO station to CHAdeMO station is not possible. The only way you can simulate long CHAdeMO charging trips is if you go in a circle around one of the cities that does have CHAdeMO stations. I drove my 1st generation Focus Electric between Texas and Colorado several times. On those trips I never drove faster than 60 mph and I often had to drive at 40 mph to make range. In cities driving slow it can get a little hairy but on the VERY long four lane highways between cities in Texas the traffic is light enough that you can pretty much travel at any speed you want. Once the Electrify America DCFC stations get installed I’m planning to drive my 2018 Leaf to Colorado and hopefully on many other long trips such as along the Gulf Coast to Florida. I know the Nissan Leaf has limitations, just like ALL EVs. With careful planning and a little patience these long trips can be… Read more »

The fact he has to spend time doing all that is a fail in it of itself. Stop being a cheapass and use liquid cooling TMS already, Nissan!


Maybe it can be about the journey, and taking in the experience, enjoying the sights and the feel of the open road, instead of just “Hammering it” to the next destination as fast as possible!


With an ’18 Leaf, you’ll have pleeeeeenty of time to enjoy the sights! Mainly of fast food restaurants or strip malls (if you’re lucky) while waiting for your Leaf to “fast” charge.

Bill Howland

Hehehe fast food restaurants and strip malls. You forgot the time the owner’s manual says to let the CAR REST before even Starting to Plug-In to the fast charger, allowing the battery time to cool prior to charging.

And to think Nissan Engineers used to laugh at the 2011 Volt’s (per them) Overly Complicated arrangement.

Yeah, the complication is that with 3 different methods of cooling depending on the temperature, the VOLT has always efficiently charged and discharged, and KEPT all its capacity, even when having to cool the battery

Murrysville EV

If any article can explain why EVs aren’t mainstream, this is the one.


Why the Nissan Leaf won’t be mainstream.


Most sold EV isn’t mainstream. Only in the Tesla bubble.


This supports my contention that this car was primarily designed, tailored, for the Japanese market, which is fine, but then don’t come out and say it’s a world car. How does it perform if it’s in AZ or FL? Though there should a reasonable expectation that people will take care of their cars and not drive them like idiots the need for a long detailed list of guidelines and constraints to follow to insure their batteries don’t overheat, is just too much to take.
The Leaf is not really designed to be a long range high speed car, it can’t be.
As a city runabout in temperate climate it’s passable, otherwise I would pass.


Talk about the wrong car for a road trip. 10 and a half hours! The only sensible way to travel 376 miles with a Leaf is being transported by a flat bed truck.


Hilariously, that would have probably been much quicker too.


In fairness to James, he did the trip twice as fast as a bicycle.

Bill Howland

Let’s hope Nissan doesn’t decide to produce Electric Bicycles that need to be ‘rested’ prior to charging.


wow and you cycle twice as fast as pros


And you do math as well as my dog.

It’s much better and easier to buy an electric vehicle with liquid cooling. As everyone knows Nissan has the most wilted batteries and has needed Liquid cooling like almost every electric already has. It makes batteries last 10 times better. Slowing down or waiting to charge at slow speeds is not a good answer.
Rumor has it the new 60 kWh LEAF will have liquid cooling. That will make a BIG improvement for Nissan and the LEAF. I had a 2011 and 2013 but both failed in Phoenix AZ. Other areas will see it fail if they are HOT and even cooler areas but not as fast.


I just turned in my 2015 S for a 2018 S this past week. It was a 100 degree day like usual and it had 88% SOH.

Maybe 5% off the median trend but in no way did the batteries fail in the blazing Central California heat.

Texas Leaf

The battery overheating issue doesn’t even occur until the second or third fast charge. Most people that buy the Leaf won’t charge that many times on a single trip more than a couple of times a year. The Leaf has enough value that having to take a few minutes longer to charge a couple of times a year should not really be an issue.


“376 mile non-stop. How I kept battery temperature down”

This is bad publicity for EV’s.

It is abhorrent to see that you have to understand and plan around these kinds of unnecessary technical limitations. EV’s nowadays are supposed to be mature technology: just drive the d*mn thing as you please.

EV’s are for the masses, not some science project for die-hards. Nissan grow up! You can do much better.


I think Nissan and Tesla do not recommend charging greater than 80 or 90% when quick charging. Takes too long after that point and it is just cooking the lithium. I hope the 40kWh batteries turn out to be better than the 30kWh battteries. We love our 30kWh battery compared to the 24kWhs we have now. The 30’s are totally awesome, great range, and they improved the range estimator. If you have a 30kWh battery be sure to check and see if it needs the software update.

Great news the Electrify America chargers are being installed. Great progress so far. This will make it easier for some people to adapt and adjust to a new better EV lifestyle.

Before buying an EV be sure the range meets your specs and allow for some diminishing range for weather extremes and hill climbing. You never get back what you put into climbing those hills.
