Rolls-Royce and Flanders Electric to develop hybrid retrofit solution for mining trucks

Green Car Congress

It integrates mtu engines, batteries and hybrid control systems, and Flanders drive train solutions. The mining truck hybrid concept recovers braking energy using the mtu EnergyPack battery system. This energy is then fed back to power the wheel motors, allowing the diesel engine to be downsized.

A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

Green Car Congress

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. The BISG is connected to a 48 V (nominal battery) and also typically to a 12V powernet via a DC/DC convertor.

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. The rear axle differential in the quattro powertrain and the battery in the trunk also factor into this balance.
