Nissan introduces new electric-motor drivetrain: e-POWER to customers
Nissan today introduced its new drive system called e-POWER to customers. It marks the first time that e-POWER technology is available for consumers, marking a significant milestone in the electrification strategy under Nissan Intelligent Mobility. e-POWER borrows from the EV technology perfected in the Nissan LEAF, the best-selling pure electric car in history. Unlike the LEAF, e-POWER adds a small gasoline engine to charge the high-output battery when necessary, eliminating the need for an external charger while offering the same high-output.
The Nissan e-POWER system features full electric-motor drive, meaning that the wheels are completely driven by the electric motor. The power from a high-output battery is delivered to the e-POWER’s compact powertrain comprised of a gasoline engine, power generator, inverter, and a motor. 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 originates from the engine and not just the battery.
This system structure generally requires a bigger motor and battery 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. 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. The e-POWER system allows you to enjoy all the benefits of an EV without having to worry about charging the battery.
