PRESS RELEASE:
Concept: The new Mitsubishi Plug-in Hybrid System brings a major increase in range and environmental performance
The MITSUBISHI Concept PX-MiEV is a concept for a new-generation plug-in hybrid crossover that delivers both
outstanding environmental and road performance. Extending the active range of the i-MiEV city car, this concept also satisfies the need formobility that combines occupant comfort with powerful performance.
The MITSUBISHI Concept PX-MiEV is powered by the all-new Mitsubishi Plug-in Hybrid System which is designed primarily to drive the vehicle in all-electric mode while using a gasoline engine to generate electricity and to assist the electric motors as and when required.
Depending on the energy remaining in the drive battery and on driving conditions, the system automatically switches between three drive modes: all-electric EV, on-the-move generating EV, and Motor + Engine. The system allows the MITSUBISHI Concept PX-MiEV to return super-low fuel consumption figures. The concept is fitted with Mitsubishi’s new S-AWC (Super All Wheel Control) advanced vehicle handling control system that is built around torque and braking control at each wheel and incorporates electronically-controlled E-AYC (Electric-powered Active Yaw Control) which uses a differential motor to control rear wheel torque split.
Among the many features that makes this concept car the crystallization of Mitsubishi Motors’ wealth of automotive environmental technology is the cocochi-interior which embraces occupants in a very comfortable and healthy cabin environment. Providing very high levels of both environmental performance and economy, the MITSUBISHI Concept PX-MiEV stands apart from conventional hybrids that rely mainly on engine power as it significantly extends the possibilities offered by the EV.
Mitsubishi Plug-in Hybrid System
Selection of drive modes delivers smooth and comfortable performance over all kinds of roads
The new Mitsubishi Plug-in Hybrid System that powers the MITSUBISHI Concept PX-MiEV maximizes the strengths of the EV: zero drive-time CO2 emissions*, powerful road performance with the gutsy torque inherent to an electric motor, and very quiet operation. The new system also incorporates a high combustion efficiency 1.6-liter MIVEC gasoline engine that is used either to turn a generator and supply the motors directly with current or charge the car’s lithium-ion drive battery or, at higher vehicle speeds, to augment the motive power supplied by the motors.
The result is a major increase in cruising range. The Mitsubishi Plug-in Hybrid System features Mitsubishi Motors’ new MiEV OS (MiEV Operating System) that constantly monitors the charge and discharge of electrical power depending on driving conditions and the remaining energy in drive battery and selects the optimum drive mode through integrated control of the EV components and the gasoline engine. Minimizing power consumption, the system delivers road performance that is comfortable, safe and reassuring at the same time.
At low to middle vehicle speeds the MITSUBISHI Concept PX-MiEV runs in all-electric mode with the drive battery supplying current to its motor(s). When the remaining energy in the drive battery falls the system switches to series hybrid mode, automatically starting the gasoline engine to turn a generator that supplies the motor(s) with electrical power. At higher vehicle speeds the system switches over to parallel hybrid mode adding the gasoline engine with its higher combustion efficiency at high revolutions to provide more motive power to the wheels. This means that depending on circumstances, at higher vehicle speeds the system can add motive power to the motors, increasing road performance. When decelerating, the system switches over to regenerative mode, using the motors as generators to charge to drive battery. In these ways, the Mitsubishi Plug-in Hybrid System switches between three drive modes depending on driving conditions and remaining energy in the drive battery: all-electric EV mode; on-the-move generating EV mode; and Motor + Engine mode.
The system also incorporates the ECO mode found in the i-MiEV production model that reduces motor output and increases the amount of kinetic energy reclaimed when decelerating to provide low-consumption and environment-friendly performance. In ECO mode the system also controls the operation of the air conditioner compressor to minimize the vehicle’s overall power consumption.
