Nissan has developed a parallel-powertrain hybrid system which connects an electric motor to the engine and transmission via two separate clutches. It basically sits between the engine and the transmission. This also eliminates the need for a conventional torque converter. Nissan used a rear wheel drive Infiniti G-Sedan equipped with this system as a Nissan Hybrid Electric Vehicle demonstrator.
The parallel-powertrain hybrid has 4 modes:
- Idle-stop:The electric motor is powered by lithium ion batteries to save on fuel.
- Normal driving:The engine powers the electric motor as well as charges the battery.
- Acceleration:Both the engine and lithium ion batteries power the motor.
- Deceleration:Brake energy regeneration.
The lithium ion batteries that power this system are sourced from AESC, a joint venture between Nissan and NEC. Look after the jump for a photo of the battery pack and two videos of the Nissan Hybrid Electric Vehicle.
Looking to sell your car? Sell it with Carro.
Hybrid is becoming increasingly popular among car manufacturers…. Is it really good? I read in a few articles citing that hybrid engines emit more pollutants as compared to conventional engines…
idknl : that is true, when the hybrid engine is 3.0l hybrid car…what’s the point of hybrid when u have a big engine on board?
Yes, It might be good to save you few dollars of petrol, but don’t forget you have already PAID in advanced in order to own this so-called HYBRID car. THe investment is too high, no point to use it, unless you can use it forever. If only use for 5 to 7 years, YOU must Loose all your investment.
Bet you the CAR price must be VERY HIGH compare to normal engine. Not a good move to save you few CENTs. Therefore, using old technologies is the cheapest way at the moment.
Actually, HYBRID is for RICHman toys not for us. DOn’t be COnfused!
My idea of a hybrid car would be an electric car with a small engine to recharge the batteries, and to give a little bit of push when needed.
I want to sell this “intellectual property rights” to Proton. :)
I hope they could come out with this kind of electric hybrid in 2010.
1. The car would be fully run by twin/modular electric motor.
2. At idle only air-conditioning motor works (depend on where you live).
3. At normal cruising speed one motor powers the car.
4. During acceleration two or multiple motors powers the car. The engine could also kick in during acceleration
5. During braking/deceleration, the motor regenerates energy.
6. When battery power below certain level, the engine kicks in to recharge the battery.
7. When the battery fully recharged, the engine stops.
8. You could also recharge at your home at nights.
9. The small engine could be below 1000CC. It could even be below 500cc.
10. The modular motor would also means that you could add additional motor parallel with the existing ones.
11. The battery could also me modular. You could add additional batteries in parallel with the existing ones when the need arises.
just a thought!

Oh….. I forgot…
Proton already sold off MV Agusta..
There goes their small engine supplier…
sigh..
Now they have to source out the small engine for the electric hybrid somewhere else..

Heck,
I could just throw in Jalan Pasar’s diesel generator into the car.
Hmmm who want to finance my research?

I detect a serious FLAW.
Lithium ion batteries.
Anyone who uses a lap top knows lithium ion batteries loses 30%-40% of its chargable capacity in 2 years.
Should be polymer batteries.
I don’t think the Nissan presents anything new as far as hybrid tech is concerned. It’s using similar tech as the venerable Toyota Prius.
Anyhow, I believe the future of car propulsion is Mitsubishi’s MIEV. Electric motors placed inside the wheels are the way of the future.
It will be a very very long time before a car maker can come up with a Hybrid that is cheap to own, cheap to service and replace
finally, a hybrid that isn’t ugly, take off those “hybrid” stickers though
Ya, lithium ion battery does not sound practical to use here. But as long as there are optional electrical source, it can be change. I believe battery would be easy to change or swap with different material as long as the voltage is the same.
But will be another major cost to maintain that battery pack.
Minyak expensive? Lithium ion battery?
MIEV is the future. Even Lotus is in it.
Check this article out.
The Lotus Eigne is a design study on an electric sportscar with a 3+1 seating arrangement that was created by David Fearnley, a graduate from the Transportation Design Course at Northumbria University. The Eigne’s powertrain consists of four in-wheel electric motors that offer the sports car rear biased four-wheel drive. The electric motors are powered by a set of batteries that are sandwiched in the floor pan.
According to Fearnley, this solution not only keeps the batteries cool and lowers center of gravity for better handling, but it also eliminates any obstacles on the floor pan allowing a 3+1 seat layout.
What did I tell ya
whatever la…..let the experts do their job….and let the technology matured one day……
