Which of the following describes an EV drivetrain that can transmit power from two sources simultaneously?

A parallel hybrid drive is characterized by its ability to utilize power from both an internal combustion engine (ICE) and an electric motor simultaneously. This configuration allows for more efficient operation and flexibility in power delivery, as it can leverage the strengths of both energy sources depending on driving conditions.

In a parallel hybrid system, the vehicle can operate using the electric motor alone, the ICE alone, or a combination of both, which is particularly advantageous for accelerating and cruising. The simultaneous transmission of power allows for better fuel efficiency and reduced emissions compared to traditional combustion engines.

In contrast, a full electric drive solely relies on electric power, while a series hybrid drive utilizes the ICE to generate electricity to power the electric motor, but it does not transmit power from both the ICE and electric motor at the same time. The term "3-phase series drive" generally refers to a type of electric motor design and does not pertain to the mechanism of power transmission from two different sources.
