e-POWER delivers a responsive drive with smooth acceleration like an EV.
- The e-POWER system allows you to enjoy all the benefits of an EV.
- e-POWER delivers massive torque almost instantly, which enhances drive response and results in smooth acceleration. Also, the system operates very quietly, much like a full EV.
- Because e-POWER can drive engine at most efficient point, its fuel efficiency is comparable to that of leading conventional hybrids, especially during around-the-town commutes.
e-POWER borrows from the EV technology perfected in the Nissan LEAF, adding a gasoline engine to charge the high-output battery when necessary. This eliminates the need for an external charger, while offering the same high output as an EV.
The Technology of e-POWER
The e-POWER system offers full electric motor drive, meaning that the wheels are completely driven by the electric motor. e-POWER is comprised of a high-output battery and the powertrain which is integrated with gasoline engine, power generator, inverter and a motor. In conventional hybrid systems, the wheels are driven by an electric motor and a gasoline engine. However, in the e-POWER system, the gasoline engine is not connected to the wheels; it simply charges the battery. And unlike a full EV, the power source is the engine, rather than just the battery.
This system structure generally requires a bigger motor because the motor is the only direct source to drive wheels. This has made it hard for the automotive industry to mount the system in compact cars. However, Nissan has cracked the code and learned how to minimize and reduce weight, develop more responsive motor control methods and optimize energy management. As a result, e-POWER uses a smaller battery than the LEAF, but delivers the same driving experience as a full EV.
