Valeo Unveils its Specific Technologies for Electric Vehicles Featured on its Show Car at the Paris Motor Show
PARIS, September 30, 2010; Valeo is presenting an electric show car at the Paris Motor Show. This demonstration vehicle showcases a wide range of innovative technologies that increase the autonomy of electric vehicles.
Valeo's ambition is to become the preferred partner of automakers in reducing CO2 emissions, and the show car demonstrates both the Group's expertise and that of its partners in the area of electric drivetrain and thermal management, as well as in products that reduce the vehicle's energy consumption and weight.
Power electronics, improving efficiency and extending range
The electric motor is controlled by an inverter, a component with considerable impact on performance. The high efficiency of Valeo's inverter helps to extend range by reducing the consumption of the drivetrain. The inverter also shares part of its circuit with the battery charger and the motor, helping to reduce mass and cost.
Thermal management, optimizing energy flows
Valeo's new thermal architecture for electric vehicles has three interacting fluid loops that recover energy where it is lost and deliver it to where it is needed. This global architecture guarantees the reliability of the drivetrain components, passenger comfort and maximum range.
Thermal accumulator: 10% extra range in cold weather
Valeo's new thermal accumulator stores a considerable amount of heat when the battery is charging. This source of heat, independent from the battery, extends range by around 10% in cold weather. Alternatively, Valeo has developed a heat pump system that reduces the electricity requirement for heating and extends range even further.
Optimized air-conditioning compressor
The show car's air conditioning has an electrically driven scroll compressor, which offers high efficiency, low noise and vibrations, and reduced size in order to facilitate its integration into the vehicle.
Thermal management of the battery to deliver maximum energy
The temperature of the lithium-ion battery is controlled by a water loop, which is hot or cold according to the need, and which delivers maximum energy in all circumstances. Valeo also offers alternative solutions, including an air circulation system, a direct cooling system using a refrigerant, and a reversible thermo-electric hot-cold system.
Smart key to communicate with the vehicle
The user has a smart key which displays the battery's charge level up to 500 meters from the car. It can also order the car to activate climate control prior to travel, by turning on the heating or air conditioning while the vehicle is connected to the grid.
Low consumption low beam LEDs
20W low beam LEDs provide equivalent light to 60W halogen bulbs. When used with front and rear LED position lamps, this technology alone increases range at night by at least 2%.
New multifunction control panel
The show car's dashboard has a control panel with a particularly high-quality finish. It stands out both for its style and for the ergonomics of the various user interfaces. In order to meet increasingly exacting demands for quality, the climate control and radio functions have been grouped together, reducing the size of the panel and standardizing all the functions that interface with the driver or passengers.
New safety and driving assistance functions
Valeo has a system that detects pedestrians on the vehicle's trajectory and emits a sound signal targeted at the area in which they are located. In order to do this, the show car has cameras and ultrasonic sensors that ensure this as well as additional functions: automatic docking (automatic cable-free connection), semi-automatic parallel or perpendicular parking, assistance exiting a parallel parking space, automatic switching between high and low beams, BeamAtic(R) Premium, speed limit sign recognition and lane departure warning.
Revolutionary new wiper system
In place of the traditional nozzle spray system, the AquaBlade(R) wiper uses a tube inside the blade to spread the washer fluid evenly across the windshield. Unlike the spray system, therefore, it preserves visibility during wiping, and halves the amount of washer fluid required. Valeo has also developed direct-drive synchronized motors with no linkage between the two wiper blades. These innovations reduce the weight of the system by a total of 3.7 kg.
Valeo is an independent group, fully focused on the design, production and sale of components, integrated systems and modules for the automobile industry, mainly for the reduction of CO2 emissions. It is one of the world's leading automotive suppliers. The Group has 117 plants, 21 research centers, 40 development centers and 10 distribution platforms and employs 56,000 people in 27 countries worldwide.
