Rethinking next generation electric vehicles

Rethinking next generation electric vehicles

Electrification is accelerating with multiple technology and architecture options. FORVIA is at the heart of research and innovation efforts to help automakers make the right strategic choice across powertrain, interior and electronics technologies.

Battery research with Collège de France

Battery life is a key challenge for electric vehicles. But what actually happens inside an electrochemical cell when it’s part of an energy system is less well understood. In a joint research project, FORVIA and Collège de France set out to explore how sensors could be used to measure temperatures within a battery cell to improve thermal management and durability. Using fiber optic techniques from medical science, researchers were able to ‘see’ and monitor temperature evolution in real-time in a system of interconnected cells similar to those in a conventional battery.

This pioneering research has led to three patents and shown the value of new diagnostic and testing approaches for industrial applications.

Extending range and comfort through seating

Battery electric vehicles present new design opportunities : the size and integration of the battery pack and related energy systems define the available interior space. Building on our leadership in seating and seat structures, FORVIA has created the market’s most compact and lightweight seat platform to improve battery storage configurations within electric vehicles. This seating concept is streamlined and sustainable: it includes structural parts made from green steel, new compact cushions and smart actuators connected to stepless tracks for a more natural adjustment motion. In addition to extending the C-SUV electric vehicle range by up to 40km, it creates a more comfortable experience for passengers in the rear through improved legroom. It’s a good example of FORVIA’s expertise in cockpit design and energy management for future electromobility

Coolant Control Hub : efficient thermal management

Thermal management is key to safe electrification. The distribution, conversion and use of power creates heat that can reduce the life of components and cause safety risks when overheating. Conversely, too cold environment temperatures reduce the efficiency and lifetime of electronic components. Efficient thermal management improves the performance of electric vehicles in terms of battery life, powertrain efficiency and passenger comfort. FORVIA’s Coolant Control Hub combines all cooling loops needed to cool the battery and power conversion devices, the electric motor and the vehicle interior while reducing the number of components by up to 50%. Through a modular design adapted to different electric vehicle systems, we reduce the complexity, cost of materials and logistics, as well as efficiently recover energy to provide on-demand heating and cooling to improve the range of electric cars.
