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.

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.
