Starting this year, Hyundai and Volkswagen will introduce a parallel hybrid configuration, relying on pure electric power, additional power, regenerative braking system and stop / start. How that is done, connect the hybrid to drive automatic transmission. For this, the system no longer uses two electric motors, only one.
This technology will be used Hyundai Sonata hybrid on the motion of the front wheel and was followed by the Kia Optima. While applying VW Touareg and Porsche Cayenne on hybrids.
Both companies use computers to control the clutch work located between the engine and electric motor. Clutch used by Hyundai, many types of plates (multi-plate) is muted in oil (wet). Electric motor, capable of producing power 30 kW, 38 kW, while Volkswagen.
How It Works
How it works, when the clutch is released, the electric motor rotates through an automatic transmission to run the car (only rely on electricity). Both systems start working when the car was first run.
When the clutch is operated and engine life, power transmitted to the transmission through electric motors. Electric motor rotates only as a component of the flywheel (at Hyundai’s system). At VW, if necessary, the motor functions as a generator.
If there is a need, an electric current from the batteries supplied to the electric motor to accelerate or increase the engine power. When the car braked, the motor works as a generator (regenerative braking).
Hyundai adds motor / generator of high voltage-driven belt, 8kW at 2.4 liter engine. Moto and generator placed in a conventional generator. His job, start the engine and 270 volt charging voltage that allows the machine to stay alive despite the car to work with pure electric mode.
Compared with the larger motor generator and incorporated in other systems, this design cheaper. Nevertheless, in order that all the hybrid system with one motor function longer need additional couplings, such as torque coverter as used by VW. Hyyundai not use to make the system more compact and efficient.
