.: NisSaN LeaF :.

Goodbye gas. Electricity is the new reality.

Powering the Nissan LEAF.

Given that there has been so much talk and so many wise words from so many different directions about our all-electric future, it can almost go unnoticed that the one thing no one has actually gotten around to doing is translating a single syllable into something a normal family with a normal budget can go out and buy.

Until now.

The 2011 Nissan Leaf is not a low-volume slice of automotive exotica like a Tesla Roadster, nor is it an electrified version of a conventional gasoline car like the Mitsubishi i MiEV, and it is certainly not a plug-in hybrid like a Chevrolet Volt or a conventional hybrid like a Toyota Prius. The 2011 Nissan Leaf is a brand-new, purpose-built, mass-produced, battery-powered family car and, as such, the very first of its kind in the world. And we've driven it.

Chevrolet Volt

But is it a real car for real people?

You Say You Want a Revolution
The moment of truth is upon us. We're in the East End of London in a large concrete parking lot upon which Nissan has marked out a track for us to sample the 2011 Nissan Leaf. Actually, two Leafs are here today. One is for static assessment, and it cannot be driven. The car that can be driven is a late-series prototype, and this one wears the body of a Nissan Tiida, known as the Versa in the U.S. Underneath the bodywork, however, this car is pure Leaf. It is very like the car that John O'Dell, editor of's Green Car Advisor, drove last summer.

Before you even slot the shift lever into Drive and tentatively press the throttle, the 2011 Nissan Leaf has done much to win you over. For a start, there's no reason not to have one — in design terms, anyway.

This is a full five-seater with a conspicuously large trunk. You sit a little higher than you might expect because there are 48 lithium-ion battery modules under the floor, but that's no bad thing. The cabin is spacious, airy and promising. The electronic dashboard works particularly well, using state-of-the-art graphics to present almost certainly more information than you will ever need, a way to reassure you that the Leaf is not going to run out of electrons without giving fair warning first. Nissan calls this "range anxiety" and, as we shall see, it's an understandable affliction.

The Leaf jumps forward with sufficient alacrity to make you wonder if it should not be renamed 'Leap.'

At first, the Leaf is entirely as expected. Once you're satisfied the Leaf is actually awake, you select Drive. Then one small squeeze of the throttle later, you're under way. It's not silent, not quite at least, but even in the unlikely event that your everyday steer is a Rolls-Royce Phantom, you're going to be stunned by the Leaf's smoothness and refinement.

The Fun-To-Drive Quotient
You ease the Leaf through the first corner and see a long straightaway appear, so naturally you nail the throttle to the floor, expecting acceleration of the barely discernible variety. But that's not what you get.

Because maximum torque is always and instantly available, the Leaf jumps forward with sufficient alacrity to make you wonder if it should not be renamed "Leap," a word that describes both its throttle response and game-changing technology with equal precision. Nissan reckons this electric vehicle's midrange punch is on a par with a sedan powered by a 2.5-liter V6 (probably it really means a Nissan Altima 2.5 with its inline-4, but whatever), and we'd not argue with that.
The 2011 Nissan Leaf also has a party piece, a feature quite incidental to the reason it exists but likely to add considerably to its appeal. And that is the location of the batteries under the middle of the car instead of in the trunk. Because the Leaf represents a clean-sheet design, Nissan created a platform that centralizes the weight of its heaviest components — the batteries — within the span of the wheelbase. And this bit of physics when combined with a very low center of gravity makes the Leaf very responsive to directional changes.

That is to say, all this makes the Leaf implausibly good fun to drive. OK, this is no Porsche Cayman, but when your expectations on the dynamic front are precisely zero, anything comes as a pleasant surprise, so the Leaf's ability to corner both flat and fast adds up to considerably more.

The bottom line is that currently the 2011 Nissan Leaf has a range of just 100 miles, and that's worked out to the U.S. LA-4 driving cycle (the original EPA city driving cycle, before the current FTP cycle was instituted), and this means that even Nissan admits that the car's owners are going to struggle to achieve it. Moreover, the Leaf will top 90 mph, but it won't travel 100 miles at that sort of speed — 60 miles is more like it, we're told. So this confirms what we all know about electric cars, which is that they are meant for city streets, not interstate freeways.

It's also useful to remember that it takes eight hours to recharge a Leaf with an industrial-type 220-volt hookup, though you can get an 80 percent recharge in 30 minutes from a specialized high-energy recharge station.

The math still adds up for most people, since we live in cities. And, as we're constantly reminded, 80 percent of us cover less than 60 miles daily. So Nissan considers the Leaf to be an eminently viable proposition as a result.

Besides, the Leaf also does much to minimize any residual range anxiety that you might have. Its navigation system is hooked up to a global database, so as the charging infrastructure expands, the nav will automatically update and always be ready to take you to the nearest power supply. Over and above that, the car's operational radius is displayed on the nav screen, so if you program a destination that's beyond the circumference, the nav will not be shy about letting you know.

You can even talk to the 2011 Nissan Leaf through your mobile phone, telling it, for instance, to warm up its interior on a cold morning while it's still parked and charging in your garage, saving you battery life and a cold backside. Once it's charged, it will send you a text saying it's hot to trot.

The Cost of Being Green
Of course what you pay for the electricity and how clean it really is depends on prices that change and the kind of power station in which the electricity was generated, but it's still safe to say that the Nissan Leaf's cost per mile traveled is a small fraction of what it would be for a car of the same size that burns gasoline.

But there's another saving, too. Where a conventional car needs an annual checkup, the Nissan Leaf effectively looks after itself. In fact, Nissan says the only routine maintenance required at the dealer will be the renewal of brake pads, and since the Leaf's regenerative braking system minimizes pad wear, it could be some years before the car needs any maintenance at all.

In around five years, however, the Leaf's lithium-ion batteries will only take around 80 percent of their original charge, so you might feel inclined to change them, not least because the replacements will almost certainly have far greater range than the old ones even when they were new. Indeed Nissan says it has targeted a cruising range of 300-350 miles for the Leaf, though the company admits the technology that will achieve it does not currently exist.

Will This Car Succeed?
It's the million-dollar question — or multibillion-dollar question, if you're Nissan. Certainly the 2011 Nissan Leaf will prove an outstandingly able device for delivering urban mobility. The immediacy of its motor response coupled with its unforeseen dynamic nimbleness will make light work of heavy traffic and there really is very little for the range-anxious to fear so long as you remember to put the plug in the wall at night.

But as with other EVs we've driven, the 2011 Nissan Leaf will have to wait for the rest of the world to catch up with it. Only when it's possible to recharge your Leaf with another hundred miles of power in the time it takes to knock back a coffee will this car's true potential be unleashed. And only when batteries are capable of sustaining the Leaf for more than 300 miles or more will this and other EVs stand a chance of prevailing over the conventional automobile with an internal-combustion engine that has served us so well and for so long.

Don't hold your breath waiting for that to happen, though. Even in 2050, up to half the cars on our roads will still be powered by internal-combustion engines, Nissan says. So while the 2011 Nissan Leaf is undoubtedly the start of something big, it seems the finish is so far away that few of us reading this today will even be here to see it.

When you pop the hood on a Nissan LEAF, you may notice a few things are missing. For instance, there's no starter, no alternator or sparkplugs, in fact there's no engine in the traditional sense. That's because there's no gas. Nissan LEAF runs on electricity, and though that's been around for a long time, we like to think of it as the new fuel.

To use the new fuel to run a car, you need a piece of technology called an inverter. It works a bit like a fuel pump in a traditional engine by getting fuel to the motor, but in this case, the fuel isn't gasoline; it's electricity, stored in Nissan LEAF's battery.

And just as you control the flow of gas in a traditional car, you control the flow of electricity in the Nissan LEAF with a pedal. Press down, it increases, and you speed up. Let up on the pedal, it decreases, and you slow down.

It's a simple principle. Simple and familiar.

And the way we see it, simple and familiar is a great way to think about the new fuel, and the new car as well.

.: sekadar coretan :.

Salam buat semua..
tak tahu apa yang mahu dicoretkan kali idea..tapi,teringin plk nk cerita psl pratikal ak skrg ni..hmm..

tanpa outstation,ak sekadar menghabiskan masa di office Jalinan Engineering ni..
minggu ini,sepatutnya,ak menjejakkan kaki ke Johor Bahru lagi..tempat yang sinonim dengan ak dalam musim praktikal ni..bermulanya praktikal aku 12 April yang lalu,ak akan berada di office selama seminggu kemudian outstation ke JB selama seminggu..keadaan ini berulang tapi,ianya terhenti pada minggu ini..oleh kerana ada barang yang di'order' company masih belum sampai,maka,outstation ke JB pada minggu ini terpaksa di tunda ke minggu depan..
terasa lega jugak di hati,kerana badan ini meminta untuk rehat lagi..huhu..

Jalinan Engineering bukanlah company manufacturing semata2..ak sendiri terkejut apabila sampai kesini pada hari pertama praktikal..ikutkan dalan list name company yang dikeluarkan uia,Jalinan Engineering terletak di bwh manufacturing company..tetapi,hakikatnya bukanlah seperti itu..ianya company yang terdiri daripada dua bahagian: 'communication' dan 'signaling'..commu bukanlah kesukaan aku tetapi,ak bersyukur,dalam signaling,ade juga part manufacturing yang boleh di aplikasikan..

Projek JB sentral hampir masuk ke tahun kedua,dan hanya part2 kecil sahaja yang belum siap..kebanyakan sistem perhubungan yang lain seperti bas,teksi sudah berjalan kecuali keretapi..Jalinan Enigneering mendapat tender utk pasang cctv,skrin ketibaan tren dan sistem2 yang berkaitan..itu part communication..utk part signaling,kena buat 'earthing' dan jgk pasang motor point utk keretapi tukar direction laluan..minggu depan,sekiranya tiada aral melintang,sistem di stesen lama akan dipindahkan ke stesen baru di JB sentral..dan selepas itu,khidmat keretapi tanah melayu di JB sentral bakal dirasmikan..

outstation ke JB sangat2 menyeronokkan sebenarnya..seronok kerana ak seorang yang sukakan kerja2 outdoor dan kerja2 yang memerlukan ak menggunakan tenaga badan lebih banyak daripada otak..bukannya ak tidak boleh bekerja di dalam office,di hadapan laptop,tetapi,minat aku bukan di situ..tetapi,ak tak dapat nafikan,kerja2 di sana memang memenatkan..di tambah dengan perjalanan ke sana yang memakan masa hampir 5 jam..tetapi,cabaran seperti inilah yang aku suka hadapi..ak telah belajar teknik 'earthing'..kerja di tepi landasan keretapi di bawah cahaya matahari yang terik..bermula dengan menggali lubang di sekeliling location box utk menanam ''copper rod' dan 'copper tape',kemudian welding utk joint 'copper tape' dan 'copper rod'..tujuan ditanam 'copper rod' dan 'copper tape' ini adalah utk kebumikan current apabila petir menyambar landasan keretapi..sebab tu la kena buat kerja2 ni sewaktu cuaca cerah..kalau buat waktu mendung,n hujan,alamaknya,cari pasal la..

nasib baik jgk menginap tu kat hotel,boleh la melepaskan penat lelah setiap malam dengan tidur di tempat yang agak selesa..hehe..kurangnye sikit,tak sempat nk berjalan melawat tempat2 menarik kat JB la,satu hari duk kerja,peluh atas sampai bawah,fikir nak balik hotel rehat je la..tapi,takpe,sekurang2nya,kenal la jugak sekitar bandar JB ni..sempat jgk sebenarnya jalan ke johor jaya n kempas..tu pun sebab pergi beli 'copper rod' dan barang company..

sempat jugak ambil gambar sebenarnya..utk present kat lecture nanti la ni..

gambar ni bukan utk present =p

tengah membersihkan 'mould'

cek connection n ready utk 'ignition part'

testing microfone..bukan betul pun..hehe..

tanam 'copper rod'..tu baru 2 batang..besenye 5,6 batang..

itulah sedikit sebanyak gambar dan coretan kali ini..lame sgt tak update..ak telah habiskan sebulan satu minggu daripada 3 bulan sesi praktikal aku..masih berbaki tidak sampai dua bulan..semoga aku mendapat lebih banyak pengalaman yang berguna utk digunakan pada masa akan datang..amin..=)
