e-Powertrain
Lightweight, compact and high-efficiency powertrain for electric vehicles EVs
The e-Powertrain powers our EVs and removes the need for an internal combustion engine. It is a lightweight, compact system that produces extremely low vibrations and generates instant torque. These elements combine to deliver a high quality, smooth and very responsive drive.
The e-Powertrain’s key components are its inverter, high-power electric motor, reduction drive and power delivery module (PDM). The unit was developed to thrive in a range environments around the world, displaying high performance and high durability in all of them.
Feature
Further enhancement to the Nissan LEAF’s powerful acceleration
Technology mechanism
The main units of the e-Powertrain each have their own functions.
Motor
Generates the power for moving and the regenerative braking power during deceleration.
Inverter
Utilizing the motor it converts direct-current electricity to alternate current when driving, and then recovers energy by converting alternate current to direct current during deceleration (regeneration).
Reduction drive
Modulates the rotations of the motor and transmits power to the wheels (drive shaft), similar to a conventional transmission.
PDM (Power Delivery Module)
Integrated unit with charger for charging alternating current to high voltage battery, DC/DC converter that converts high voltage to low voltage and junction box that distributes high voltage to every unit, blocking a current pathway like a breaker when anomalies arise.
