All Electric Nissan Leaf Unveiled

E-mail Print

I've actually come out of writing retirement for the summer to bring you what I think is a pretty cool story: Nissan has finally given us some details about their upcoming "Leaf" full-electric vehicle (EV).

Unlike the Tesla roadster, this isn't designed to be an expensive rocket on wheels, but what it does aim to do is to bring electrics into the mainstream market: Nissan is going to start making this car available in Japan, most European countries and the US around 10,000 - 15,000 Euro ($15,000 - $20,000 US), a common price point in the compact market.

The Leaf is powered by Lithium ion batteries using a custom chemistry developed by Nissan which are expected to give the car a 160 kilometer (100 mile) range and are designed to be charged to 80% in about 20 minutes using a quick-charging system. If charged via a standard 220V socket, expect your standard 8 hour recharge time and even longer from a standard North America wall socket.

The electric motor packs quite a punch at its rated 80kW/280Nm, (107-hp and 207 ft-lbs of torque) which should make it really quick off the line despite the electronically-limited 145 Km/h (90 mph). While electric motors tend provide huge amounts of torque across the entire RPM band, higher RPMs lead to higher power draw and thus less range.

"Our car had to be the world’s first, medium-sized, practical EV that motorists could afford and would want to use every day. And that’s what we’ve created. The styling will identify not only Nissan LEAF but also the owner as a participant in the new era of zero-emission mobility" said Masato Inoue, the Leaf product manager.

The Leaf will begin production in Oppama, Japan, and will soon be expanded to Nissan's Smyrna, Tennessee plant. The company also expects to launch two more EVs in the next 3 years, positioning itself as a strong contender in the electric market.

"The Nissan LEAF is a tremendous accomplishment - one in with all Nissan employees can take great pride,” said Nissan President Carlos Ghosn. “We have been working tirelessly to make this day a reality - the unveiling of a real-world car that has zero - not simply reduced - emissions. It’s the first step in what is sure to be an exciting journey - for people all over the world, for Nissan and for the industry."

I'm really excited about this one, kids. This is a car that most people can actually afford and once governments start installing electric charging infrastructure, stopping for 20 minutes every 160 kilometers doesn't sound so bad. Hopefully this can be used as a significant stepping stone to a world of quiet running, quick and practical electric cars with infrastructure to back them.

 

EEStor Permittivity Testing: It's a Pass!

E-mail Print

Good old EEStor released a third-party verification of the permittivity of their insulating material - the verdict? It's a pass and expectations have been met from -20 degrees celcius to 65C. Sorry, I know I'm here partying all on my own, so let me back track a bit and give a bit of background on this...

EEStor Cell

As most are probably already aware, batteries have always plagued the electric vehicle for a mass of reasons: they don't offer sufficient range, are too heavy, too costly, too big, don't discharge fast enough, don't charge fast enough and performance degrades over time. Yeah, that's a big list of flaws and so many may be surprised that I'm a big proponent of the development of electric vehicles. One of the reasons is because of a lot of the cool technologies on the horizon such as the EEstor EESU (Electrical Energy Storage Unit). EEStor wants to pack 52KWh of energy in these things in a small package weighing in at around 300 pounds. To give you an idea of how much energy that is, most of you can probably power your houses for a full day and the more energy concious among you for a couple of days.

Now, the reason that this is such a breakthrough is because how much energy a capacitor can store is modeled by the following equation:

energy = ( capacitance x voltage ^ 2 ) / 2

What does this mean to your life? Basically that if we can increase voltage in a capacitor, we get exponential gains in how much energy we are storing. To get those really high voltages, we need to be able to place conductive plates really close together with an excellent insulator in between. The real breakthrough is in this insulating material as the permittivity testing shows that we EEStor has created a material which is hugely better than previous known materials. The independent lab verification is a huge step forward since the company has never been forthcoming about anything they do. In fact, I'd almost say that they hide as much as they can from the public almost to the point that people are thinking EEStor is some kind of scam.

Now there is of course a lot more to this plot. Lockheed Martin actually signed an exclusive deal with them about a year ago, as did a publicly traded Canadian electric car maker called Zenn Motors. When this story broke, stock at Zenn shot way, way up. In fact, let me pull a picture off of Google Finance right now for you guys!

So yeah, all the scientific mumbo jumbo actually means a lot to the future of the electric vehicle. Eventually I'll get around to posting an article for you guys which showcases some of the most exciting green automotive technologies of the future that may very well lead the way to finally replacing fuel. As always, stay tuned and subscribe to the RSS feed if you want to be updated whenever I post an oh-so-interesting article! And yes, I'll make a bigger RSS button eventually. Peace out!
