Delphi develops wiring and HVAC for LaFerrari


Delphi technologies help Ferrari reach emissions reduction goal on new limited-edition, special series model

GENEVA—March 8, 2013: When Ferrari set out to develop the most advanced and powerful vehicle the brand has ever developed, the company turned to Delphi Automotive for help with two key vehicle systems to increase performance while decreasing emissions.

A long-time partner to the legendary performance carmaker, Delphi developed one of the most important parts of the vehicle -- wiring harnesses for both the low- and high-voltage systems of the vehicle’s electrical/electronic architecture using its sophisticated software, known as the Delphi Velocity™ Tool Suite which uses integrated design, analysis, and simulation tools. When applied to the Ferrari LaFerrari gasoline-electric hybrid, the high voltage wiring harness permits power boosts, while allowing for the reduction of CO2 emissions. The high voltage wiring is used to provide power from the battery pack to the inverter and to the motors.

Additionally, Delphi worked closely with Ferrari engineers to develop a complete air conditioning system for the LaFerrari that is lightweight, provides optimal comfort for all passengers and the required cooling to maintain the high-voltage batteries at the optimum temperature.

The air conditioning system, which utilizes an electric compressor, and caters for the hybrid and electrical drive requirements, provides increased fuel efficiency, engine power availability and hybrid battery cooling control. The system also uses a newly developed heat exchanger (chiller) which cools the battery to ensure safety and durability.

Delphi’s HVAC system for the LaFerrari allows for a 3.5kW additional cooling power for the hybrid system. For passengers, this means less fuel consumption without sacrificing basic cabin comfort.

Ferrari also asked for Delphi’s involvement in the recharge area for a customized solution, leveraging the wide experience Delphi has in recharge systems developed to cater for the various norms around the world.

Since the early 1990s, Delphi has worked with Ferrari co-developing and co-designing climate control and electrical/electronic systems to meet Ferrari's very high performance and quality demands.
