Monday, 07 Jul 2008 Valeo announced today that it has signed a contract with PSA Peugeot Citroën to equip more than one million vehicles with its Stop-Start technology by 2011. “This is an important contract,” declared Thierry Morin, Valeo Chairman & CEO. “The confidence expressed by the PSA Group through this contract shows that our strategy is supported by automakers. Our objective is to develop, as of today, affordable solutions accessible to the greatest number of motorists.” Ever growing urban populations are making cities increasingly congested. Thanks to StARS, fuel consumption and CO2 emissions can be reduced by up to 15% in urban driving cycles. It is estimated that, in cities, a car spends up to one-third of its time at a standstill with the engine idling unnecessarily. In this situation, the usefulness of the Stop-Start function becomes evident, and Valeo expects it to become widely available on all types of vehicles worldwide.The StARS system automatically cuts off the engine when the vehicle is at a standstill, at a red light or in a traffic jam, for example, and restarts it silently and instantaneously when the brake pedal is released. Moreover, thanks to its non-intrusive architecture, it can be easily installed on any new vehicle, replacing the traditional alternator and starter motor. PSA Peugeot Citroën, the first automaker to adopt this system in volume production on the Citroën C2 and C3, has once again demonstrated its confidence in Valeo for its upcoming platforms. Valeo also equips the smart mhd (micro-hybrid drive) and is expected to announce additional contracts in 2008. Valeo is an independent industrial Group fully focused on the design, production and sale of components, integrated systems and modules for cars and trucks. Valeo ranks among the world's top automotive suppliers. The Group has 122 plants, 61 R&D centers, 9 distribution centers and employs 60,000 people in 27 countries worldwide.

Valeo announces today that its StARS micro-hybrid system equips the new Mercedes A and B Class.
Invented by Valeo, this system featuring the Stop-Start function, cuts off the engine when the vehicle is at a standstill, at traffic lights for instance, and then restarts it quickly and silently when the driver releases the brake pedal. It provides average of fuel savings of 9%."This technology meets end user needs for reducing fuel consumption and CO2 emissions, at an affordable cost," says Valeo's Chairman & CEO, Thierry Morin.Ever growing urban populations are making cities increasingly congested. The usefulness of the Stop-Start function becomes evident as it is estimated that, in cities, a car spends up to one-third of its time at a standstill with the engine idling unnecessarily. Under these conditions of congested city driving, fuel savings can reach 25%. Valeo expects the system to become widely available on all types of vehicles worldwide.Valeo’s micro-hybrid system already equips the Citroën C2 and C3 and the smart mhd. Valeo has also won a contract from PSA Peugeot Citroën to equip more than a million vehicles with StARS by 2011. Valeo is an independent industrial group dedicated to the design, production and sale of components, integrated systems and modules for cars and trucks. It is one of the world's leading automotive suppliers. The Group has 122 production sites, 61 R&D centers, 9 distribution platforms, and employs 60,000 people in 27 countries.

15 July 2008 Valeo announced that its StARS micro-hybrid system equips new Mercedes-Benz A- and B-class vehicles offering that function. (Earlier post.) Valeo also recently signed a contract with PSA Peugeot Citroën to equip more than one million vehicles with its Stop-Start technology by 2011. StARS (Starter Alternator Reversible System) cuts off the engine when the vehicle is at a standstill, at traffic lights for instance, and then restarts it quickly and silently when the driver releases the brake pedal. It provides average of fuel savings of 9%. Under conditions of congested city driving, fuel savings can reach up to 25%. The starter alternator is driven by a belt that can also be used to drive other accessories, such as the air conditioning compressor, the water pump or the power steering. A reversible tensioner allows power to be transmitted in both directions, depending on whether the StARS starter alternator is working as a starter or a generator.The system features a battery based on technology that accepts high numbers of charge/discharge cycles. The battery is also fitted with a sensor that enables the system to inhibit the Stop-Start function if the charge level is too low or to restart the engine if the charge level drops below a critical threshold.The StARS starter alternator is a synchronous machine with a claw rotor. It is air-cooled and uses a three-phase current that is transformed to 12 V DC voltage by a separate electronic transformer. In starter mode, it is capable of delivering a 600 A current generating enough torque to drive the internal combustion engine immediately and at higher revs than a conventional starter. The machine can start the engine in less than 0.4 seconds, before immediately switching to alternator mode.In this configuration, the electronic transformer uses MOSFET field effect transistor technology to rectify the three phases. This is one of the reasons behind the 82% efficiency of the StARS starter alternator, which is a full 10 points higher than the best conventional alternators on the market. The machine delivers a current of up to 180 A.Valeo’s micro-hybrid system already equips the Citroen C2 and C3 and the smart mhd.Valeo is developing a supercapacitor-based extension to StARS (StARS + X) to support regenerative braking and thus enable a greater reduction in fuel consumption than is possible with the stop-start system alone.The StARS + X system uses a slightly different architecture with different motor for starting and regen, and support for voltage between 14V and 30V. The floating voltage enables extended torque for diesel or large engine cold cranking, 4 kW generation for regenerative braking and extra power supplies for peak loads. (Earlier post.)
