3 Modern Age Electrified Powertrain Variants


The world is turning all tech frenzy, thereby, offering supreme comfort to the population with the introduction of relaxed amenities. With the convenience of powertrains and other electrified vehicles, not only are we contributing towards advancement but also channelized a higher ground for sustainable development.

The commercial success of powertrains is not new and has motivated manufacturers to present sophisticated electrified architectures framed across applicable engineering principles. Let us try to understand the top three powertrain designs which have achieved global recognition to modernize the current railway network.


Hybrid (HEV) Powertrain Architectures

Hybrid powertrain architecture delivers the following sub-variants:


Mild Hybrid (MHEV): It comprises of a small electric motor merged to a battery connected to an internal combustion engine (ICE). This setup supports acceleration as well as regenerative braking.

Strong Hybrid: This system includes a large electric motor linked to a battery which is further connected to a downsized ICE. Strong hybrid powertrain designs offer improved regenerative braking and phases of electric motor drive.

Plug-in Electric Vehicle (PEV) Architectures

The Plug-in Hybrid (PHEV) is tagged as a strong hybrid comprising of a downsized ICE, typically a larger generator and battery to offer extended electric range. The system delivers necessary electronics in order to charge the battery and further utilizing an electric grid to power the vehicle. The prime sub-variants include:

 Series PHEV: It should be known that ICE, battery, motor, generator and transmission are all lined in series, with a purpose to drive to the wheels that is eventually delivered by the electric motor, driven by either the ICE or the battery.

PS PHEV: The power split is similar to the PS strong hybrid; however, with a larger battery as well as the capability to push while the engine stays off. Such characteristics make this version a hit in the global automotive powertrain market.

Fuel Cell Electric Vehicle (FCEV) Architecture

For driving this powertrain variant, the source is a fuel cell which generates electricity utilizing a fuel, for example hydrogen. It either functions to charge a battery or drives a motor in order to power the wheels.
