<< Prev Page 2 of 2  The high-density, high-power and high-voltage battery (900 volts) was developed jointly by Peugeot Sport and Saft, a Total subsidiary. With over 10 years of experience in F1 and based on Peugeot Sport specifications, Saft’s engineers selected the best type of cells for the battery, which favours power density over energy, consistent with the needs of endurance racing. As one of the keys of the car performance, the battery will be completely integrated inside the car and in the powertrain’s energy-management process.“The main parameter will be to optimise how the energy stored in the battery is used,” explains Kamen Nechev, Saft’s Chief Technology Officer. “To achieve this, you need an extremely short charge-time combined with high-capacity storage cells to form a package that enables maximum power to be delivered as rapidly as possible. The most competitive solution resides in the management of charge optimisation and the amount of power available in real time.” The new battery will be located in a carbon casing inside the car’s monocoque structure, behind the driver and underneath the fuel tank. It has been designed to combine optimal durability with consistent performance in races of up to 24 hours and even beyond. Total and Peugeot Sport are responsible for the homologation of the battery which will be assembled in a new workshop at Peugeot Sport’s Versailles-Satory base, near Paris. Peugeot Sport’s collaboration with Total on the FIA WEC programme fits perfectly with the operational guidelines and job-share outlined in the plan for Automotive Cells Company, a joint venture which seeks to become Europe’s number one battery manufacturer for electric vehicles. Although the internal combustion engine delivers 500 kW (680 hp) and the motor generator unit has a capacity of 200 kW, the regulations set a maximum power output of just 500 kW during races. To adapt to the different situations in competition, the LMH powertrain functions as follows:
Before the track-testing programme begins at the end of 2021, Peugeot Sport and Total will continue their engineering, which is expected to see the powertrain run on the bench and simulator in the course of the first half of 2021. While motorsport is as a full-scale laboratory for testing new technologies, the experience of Peugeot and Groupe PSA in the field of electrified vehicles has enabled Peugeot Sport to benefit from other synergies, including close collaboration between road-car and racing powertrain engineers, on the development of systems and components. Peugeot Sport employs a number of engineers who, like François Coudrain, have had the opportunity to apply their expertise to both mass-production road models and race cars in the course of their career. This unique, valued knowhow feeds into the overall knowledge pool behind the Peugeot Sport Engineered line, the first fruit of which was the Peugeot 508 Peugeot Sport Engineered. This version of the Peugeot 508 (360 horsepower / 520 Nm / WLTP CO2 emissions: 46g / km) embodies the brand’s new Neo-Performance virtuous performance concept and offers a perfect blend of advanced technology and sporting pedigree. It is the most powerful Peugeot road car ever made and its Peugeot Sport-engineered systems are a source of inspiration for the FIA WEC programme. Last but not least, the policy of sharing information between Groupe PSA’s different motorsport departments has paid ample dividends, too, notably in terms of on-board control units and software, especially in the area of powertrain energy management (energy recovery system, power output under acceleration, anti-lag system and reduced fuel consumption). << Prev Page 2 of 2 |
