Nissan has introduced its brand new electric drivetrain system under the Nissan Intelligent Mobility electrification strategy. Christened the e-POWER, the new electric drivetrain system is, according to Nissan, a result of knowledge gained from the development of the all-electric Nissan Leaf. The Nissan Note (pictured above) will be the first Nissan model to equip the new electric drivetrain system.

How does it work? According to Nissan, the e-POWER dispense of the need for external charging port thanks to the addition of a small petrol engine driving the power generator. The engine will fire up when the battery is low on charge. This will recharge the battery as you are driving along, which helps alleviate the so-called 'range anxiety' associated with all-electric vehicles. The battery will then feed its juice to the electric motor to propel you down the road.

This is in contrast to all-electric vehicles which does not lug around the internal combustion engine (ICE), nor the conventional hybrid where the ICE takes the propulsion duty over from the electric motor when the latter is low on charge.

Nissan's e-POWER is essentially a series hybrid system and in a way, it's nothing new. However, with the e-POWER technology, Nissan has managed to make the battery smaller compared to the Leaf's battery, which helps in weight reduction and more importantly, enables the electric motor to deliver high output for smooth, powerful acceleration.
