MARELLI TECHNOLOGIES SHOWCASEDAT 2024 BEIJING INTERNATIONAL AUTOMOTIVE EXHIBITION• ‘Co-creation @speed’ area
Digital Twin
Marelli's Digital Twin is a cloud-based virtual replica of the entire electric/electronic vehiclearchitecture. It enables software developers to run simulations, testing, and validations, achieving
up to a 70% reduction in development time and 30% reduction in prototype costs.
LeanDisplay
Marelli’s LeanDisplay offers advanced local dimming performances at a much lower price point, inaddition to an improved sustainability footprint, compared to standard displays. This has beenachieved by adopting a design for manufacturing approach resulting in 40% fewer components,
through scalable optimized backlight technology – combining LEDs and proprietary lenses – and by
localizing the supply chain.
ProConnect
ProConnect is a fully integrated cluster with infotainment and 5G telematics, targeted for the China
market where many OEMs are integrating cockpit and telematics functions for entry and mid
segment vehicles to better balance performance and cost. Powered by MediaTek’s market-proven
MT8675 System on Chip (SoC), ProConnect manages both the instrument cluster and theinfotainment system, supporting up to six displays and twelve cameras, while providing 5G Release
15 telematics performance. ProConnect maximizes value for OEMs and end-consumers through theelimination of redundant components with an integrated SoC supporting cluster, IVI (In-VehicleInfotainment), and TCU (Telematic Control Unit) functions, saving up to 40% compared to traditionalarchitectures.

• Software-Defined Interior (seating buck)Marelli's 5th generation architecture and Software Defined Vehicle (SDV) technologies revolutionize
the driving experience with innovative Human Machine Interfaces (HMIs), that vanish when off andappear only where and when needed. The system, driven by the EliteCore central control unit andZone Control Unit, offers a personalized experience through CAMEX, an AI engine, and MyAvatar,a 3D-rendered avatar for intuitive interaction. Marelli's demo car showcases cutting-edge OLED andTFT displays, advanced audio zoning, and integrated monitoring systems for a safer, moreconnected, and customized driving environment. These features not only enhance comfort andtechnology within the cabin, but also provide scalable and cost-effective solutions for various market
segments, ensuring a future-proof and personalized driving experience for all customers.

• Lighting & 360° Communication
LeanLight Headlamp
Our LeanLight platform includes lighting products designed to achieve the best possible solution interms of sustainability and cost-competitiveness. Our LeanLight headlamp consists of a basic LED
module with no microcontroller required.

Laser Fiber Rear Lamp
Marelli was the first in the market to combine a LASER and thin optical fibers to create Thin Lit Lines.
This style-driven application ranges from state-of-the-art light guide integration to mazing optical
speckling LASER effects.

• Interactive Experience Lab
Zone Control Unit
Our Zone Control Unit manages chassis, propulsion, and thermal functions within the vehicle, withintegrated drivers managing the suspension and transmission. The control unit also integrates highspeed communication lines and power distribution.
Fully Active Suspension
Our fully-active electromechanical technologies provide outstanding comfort, driveability, and safetywith high energy efficiency. The technology robotizes the suspension, while the control logic activelyneutralizes the vibration and body movement when traveling at high speeds.
Integrated Thermal Management Module
Marelli is actively pursuing a smart iTMM with a high-performance component, able to thermallyinteract with the 3 main domains: battery, cabin and propulsion, it can significantly improve theoverall vehicle efficiency.
• System flexibility: specific multi-functional combined valve, with max 9 ports and 6 working
modes, Marelli’s iTMM can ensure different functions according to the external environment
conditions and the thermal needs of each subcomponent. Similar products on the market arenormally 4 mode connections.
• System efficiency: the multi-functional valve is equipped with a patented spring structure able toreduce up to 60% internal leakage and related heat losses.
• System weight: with an optimized structure design, the system weighs up to 11% less than similar
products on the market. Specifically, regarding the refrigerant manifold plate, our design uses a
die casting and pipe connect structure, resulting in 40% lighter weight than market forging plate,meanwhile the simplified structure can contribute to a simplified production process.
Wireless Battery Management System
Marelli's innovative Wireless Battery Management System offers a cutting-edge solution for theelectric vehicle (EV) market by removing the need for traditional wired connections between cellsupervisory controllers and the Main controller. This breakthrough technology not only leads tosignificant weight reduction and simplifies the manufacturing process but also allows for more spacewithin the battery pack, enabling the addition of extra battery cells and consequently extending thevehicle's driving range. Tailored to support a wide array of EV segments with medium to large battery
packs, the system is built on a scalable architecture capable of accommodating dual battery
configurations for 400V or 800V DC fast charging. Enhanced by cloud computing and artificial
intelligence, the system can accurately predict the battery pack's State of Health (SOH) and State ofCharge (SOC), ensuring a longer, more reliable service life and superior performance for EV drivers.
