Nissan has unveiled a couple of innovations, and the first is the development of a new technology that can fully charge an electric vehicle battery in about 10 minutes.
According to a report, researchers at Japan’s Kansai University, working together with Nissan boffins, have come up with tech to speed up the charging process. Currently, lithium-ion batteries can take up to eight hours to recharge fully.
In experiments, the researchers tweaked a capacitor – by using a composite made from tungsten oxide and vanadium oxide for the capacitor’s electrode instead of the usual carbon – to allow it to hold more power. Tests with the new capacitor resulted in it being able to fully recharge within 10 minutes, while maintaining nearly the same storage capacity and voltage as lithium-ion batteries, the report says.
Apparently, the new capacitor has endured repeated charging and discharging without durabiility issues, and the researchers are now planning to go further afield, utilising different materials and structures for the device, with the aim of bringing down the charge time to three minutes or less.
The report adds that it is likely to take about a decade to commercialise the technology, but the breakthrough is expected to help cut production costs for electric cars and make them more popular for drivers in a hurry.
The second one involves steel, in this case what has been tagged as the world’s first ultra high tensile strength steel to be rated at 1.2 gigapascals (GPa), which Nissan has developed in collaboration with Nippon Steel Corporation and Kobe Steel.
What’s unique about this one isn’t just its stiffness, but also its formability. Until now, high tensile strength steel involved a critical trade-off – increased strength came with increased rigidity, and with that, a consequent reduction in press formability, not to mention the challenges in spot-welding the stuff. Traditionally, only high tensile steel – rated up to 980 megapascals (MPa) – has been used in cold pressing structural body parts, requiring complex press work.
The new material changes the scene. Highly formable, it will be produced from 2013 as steel plates for use in cold pressing structural body parts, and used for centre pillar reinforcements, front and side roof rails and other key structural components.
Development of the new material was realised by a breakthrough in the ability to control its structural formation at the sub-micron level, combining hard and soft layers to achieve both strength and formability. An optimal spot-welding methodology – a proprietary process which involves careful optimisation of welding pressure, current volume and power distribution – was also developed for use with it.
The steel offers the benefit of exceeding the structural body performance of previous materials, with less thickness needed. As such, it will offer weight savings, with Nissan claiming its use will reduce vehicle body weight by up to 15 kg.

Excellent news.
Ironman technology ?
Impressive!!
now, this is call R&D.
Good job Nissan. I hope this would path the way for more cars less dependent on fuel and a whole lot safer.
What about Pedestrian safety?
Do you know that Proton Savvy, Proton Exora and New Proton Saga use high tensile steel?
The use of high tensile steel is not new hat, but the one announced pushes boundaries.
yes proton use high tensile nissan did rnd on ultra high tensile steel
No lar….Tin can :-P
even Lamborghini can burn into frames!!!
Good stuff. If practical, this quick charging could help change the landscape of hybrids and EVs.
Proton should put their money into these areas and not
Rally and F1 cos at the end of the day they gain NOTHING.
malaysian do that also malaysian sendiri not appreciating it…. make own engine bash all the way to the grave…… TYPICAL malaysian mindset… its like when u have wife you tell all the back things about her to your friend or worst to the world… “she’s a SLUT”
WTH
Rally and F1 is for Marketing and increase brand awareness especially to younger crowd.
No point in putting R&D effort but no where to sell coz nobody know proton.
Almost every car manufacturer involve in motorsports, similarly to adidas, nike, puma, etc involvement in other sports arena for their sportwear business. How do you know they gain nothing from those involvements? …unless you are the one who conduct their annual business review.
look, Nissan do R&D collaborations with universities and many other companies related to its business. read the report again, see how long does it take to be ready for production? 10 years! and how long have they involved in the R&D of the said battery?
Here, people bash Proton immediately whenever Proton announce MoU or collaboration with any other party. Do you really think you could sign MoU today and get the result tommorow?
involvement in motorsports is also part of R&D. they put the car to the extreme real-life test in rally. Cusco won’t know Satria Neo if not for Proton involvement in rally. Look at the latest APRC result, even Subaru WRX and Mitsu Lancer are smoked by Neo!
they gain the free overseas trip mah
Proof that big companies with billion of dollars that are doing all sort of RnD nowadays. The bigger money being spent out the better RnD they get.
Billions of USD. Not ringgit.
If Nissan could only bring about a full li-on battery charge at 10-min ten years on, it might be a little too late for the marque. There are rumors others are bringing 10-min charge to the marketplace in a couple of years’ time. And remember too hydrogen tech is progressing as we speak.
do you read the article or you just read the comments?trying to act smart….
wow!!. 10 minutes is super fast laa~
get it into production oredy…
my 1st car is gonna be electric.
-“dont be oil addict, oil is gonna deplete”-
For more fun to this topic, watch the newly posted podcast by engadget on their test drive of Tesla Model S. It is way cool, watched it last night.
Just for us folks here, can anyone from paultan.org get an invite to test it out too for us. even though in the podcast they did mention that no outsider are allow to drive it yet, but to get driven it one is still fun. 300 miles per charge; claim. 2012 production/deliver. but….@US$49,000.00. Guess we’r not getting it here.
Test drive for us please, members of paultan.org.
Real Steal !!!!
So what is the rate for the high tensile steel use by Proton??
My Proton Savvy’ body is 100% high tensile steel, that is why when one camry hit my back, there was not a dent, but that camry had one, and when I accidently hit one continental car, again my car not a dent but that other car had one. I think Proton Exora is 100% too.
There was an episode in Top Gear where it highlights the difficulties of charging Nissan Leaf where Clarkson stranded in Lincoln while waiting the battery to recharge. I would like to watch this episode again but with this new super fast charging battery!
I guess Nissan sees the new electric wave as a way to cast aside Toyota and Honda and take its place as the Japanese No.1. I wouldn’t mind that, really, they make okay cars.
This reminds me of an article a while back, also featured here on PT, about knitting robot grannies used to optimize moldability and strength of the body structure.
Ahh, here it is: http://paultan.org/2010/11/22/smart-454-wwt-built-by-granny-robots/
It’s fascinating the kind of innovations we’re coming up with to overcome limitations in the industry. Fantastic stuff, Nissan.

Man,
Use your correct head b4 u post any comments.
Nissan has come up with a new steel technology which is stronger and lighter.
Similar to BMW’s Novelis Fusion(TM) aka “The new aluminium(TM).”
You are instead talking about an amoured car over a ton and with an underpowered
Campro engine which guzzles due to its massive weight!
You said under power how many times I told you Gen2 top speed 200km/h surpass all standard Japanese car Campro the same standard with all Continental car likw VW BMW Mercedes etc. Remember this for the rest of your life.
Actually I read before posting any comments and I read that Savvy and Exora are made of high tensile steel. Remember the advertisement that the savvy was thrown around by a giant?
