Delphi Automotive PLC unveiled a 48-volt mild-hybrid vehicle solution; the company confirmed it is working with two global automakers and could see production within 18 months.
Showcased in a Honda Civic 1.6-liter diesel vehicle at the company’s annual investor update in London, Delphi’s 48-volt, mild hybrid technology uses the 48-volt electrification to minimize the demand on the engine, improving performance while lowering CO2 emissions by more than 10%.
This is not only a significant step forward with reinventing the electrical architecture for dual voltage capability, it is also a triumph of software. This intelligent approach to vehicle power, wiring and data management will not only improve fuel efficiency, but will also enable a world-class driving experience while providing additional power for active safety systems and increased connectivity in the car.—Jeff Owens, Delphi’s chief technology officer
The Delphi system leverages an e-charger for improved vehicle launch. Delphi’s demonstration vehicle increases low-end torque an average 25%.
According to Owens, Delphi will have a competitive advantage in 48-volt, mild hybrid systems because of the company’s deep history in system design, proprietary engine management software and expertise in electrical architectures.
One out of every 10 cars sold globally in 2025 will be a 48-volt, mild hybrid. To put that into perspective, that’s 11 million units a year—three times the volume of pickup trucks sold annually and more than half of the world’s anticipated diesel passenger car market. (Data source: IHS]—Jeff Owens
