Different configuration of parallel hybrid vehicle

#Different configuration of parallel hybrid vehicle series

The hybrid system improves driving performance and fuel consumption by using the motor to regenerate power during deceleration and store it in the battery, as well as supporting the engine by using the battery to power the motor for low-speed EV driving and acceleration. The FF HEV system is using an internal combustion engine together with an electric machine and a continuously variable transmission (CVT) on the front axle. Front Engine Rear-Wheel Drive Vehicle Hybrid System (FR HEV).Front Engine Front-Wheel Drive Vehicle Hybrid System (FF HEV).One example is Nissan, with two variants: There are several OEMs which are using this hybrid powertrain architecture for their vehicle. (1)assuming the engine stop/start is performed with an additional electric starter The states of the clutches during each mode of the hybrid powertrain are summarised in the table below. From the implementation point of view, the second clutch is part of the transmission and not as a separate component. The second clutch, allows the electric machine to be disconnected from the drivetrain and let the vehicle coast during deceleration. Also, during deceleration phases, by disconnecting the engine, we can remove its braking effect and have higher efficiency for kinetic energy recuperation. The first clutch, between engine and electric motor, allows the engine to be disconnected from the drivetrain and drive in pure EV mode. Image: Parallel hybrid powertrain with two clutches For a rear-wheel drive (RWD) vehicle, a common hybrid powertrain architecture is using an electric machine between two clutches. In a parallel hybrid powertrain, both the internal combustion engine and electric motor can transmit torque to the driving wheel, in a sequence or in the same time. Parallel hybrid powertrain with two clutches In this article we are going to focus on the different types (architectures) of HEV powertrain, highlighting the working principle and the advantages/disadvantages compared with other types. energy recuperation during braking (regenerative braking)Р В РІР‚СњР В РІР‚РЋor a detailed introduction in hybrid electric vehicles, types and their mode of operation, please read the article What is a Hybrid Electric Vehicle (HEV) ?.Most of the road vehicles with hybrid powertrain use an internal combustion engine (ICE) combined with an electric machine (EM).Р В РІР‚СњР вЂ™Р’В¬ompared with a conventional vehicle, powered by an ICE, a hybrid electric vehicle is capable of performing these functions:

Lastly, a fuel consumption comparison between the most efficient parallel solution and the series architecture is shown for the purpose of identifying the most efficient powertrain architecture.A hybrid electric vehicle (HEV) is a vehicle which is using two sources of energy for propulsion, one of them being electrical energy.

It is firstly shown a fuel consumption comparison between the two parallel powertrains, secondly a brief description of the main electric component innovations is reported in order to fully understand the effects they have on the series architectures. This paper aims to summarize the main results available in the scientific literature on this topic. In spite of this fact, in depth electrical losses analysis of this configuration and the introduction of more efficient electric component question the adoption of this powertrain as the model of energy efficiency. In particular, CVT powertrains can count the highest number of sales in the HEV industry. The large boom in the Hybrid Electric Vehicle (HEV) market sector has seen the spread of three main powertrain configurations: Discontinuously Variable Transmission (DVT) parallel architectures, Continuously Variable Transmission (CVT) parallel architectures and series architectures.
