Delphi develops new tech to halve EV charging time

By CARSIFU | 12 September 2019

FRANKFURT: Delphi Technologies is the first in the industry with volume production of a 800 V silicon carbide (SiC) inverter, one of the key components of highly efficient next-generation electric and hybrid vehicles.

The new inverter enables electrical systems up to 800 volts, significantly extending electric vehicle (EV) range and halving charging times compared with today’s state-of-the-art 400 volt systems.

The technology, which supports multi voltage platforms, is an evolution of the company’s proven high-voltage inverter and builds on 25 years of vehicle electrification experience.

Delphi Technologies 800 V inverter uses state-of-the-art silicon carbide MOSFET semiconductors (silicon carbide-based metal–oxide–semiconductor field-effect transistor wide bandgap technology).

The launch is expected in 2022, initially for a high-performance vehicle operating at up to 800 Volts.

A few days ago, the company announced that it is partnering with Cree, a leader in silicon carbide (SiC) semiconductors, to enable next generation of electric vehicles to drive longer distances, have faster charging times and improved efficiency.

“Doubling the voltage from today’s typical 400 volts brings a substantial range of benefits, both for the vehicle user and for the vehicle manufacturer,” explains Richard F. Dauch, Chief Executive Officer of Delphi Technologies.

“We have designed this technology to simplify vehicle manufacturers’ multi-voltage strategy as they extend their electric and hybrid vehicle ranges.”
