The new Delphi/Bosch drive systems use a 48 volt lithium ion battery along with electronic controllers for the battery and hybrid powertrain, a DC/DC converter, and an electrically driven turbocharger for the vehicle’s internal combustion engine. One big advantage of a 48 volt system is that it does not require expensive and heavy safety shielding the way a full plug-in or electric propulsion system does. Those systems often operate at up to 600 volts. Saving weight will be a crucial part of meeting coming regulatory standards. Delphi plans to show off its mild hybrid system, along with autonomous driving technology it has developed, at the Consumer Electronics Show in Las Vegas that begins January 5.
