Audi presents latest SQ5 TDI diesel; 48V MHEV & electric compressor

Green Car Congress

The 48-volt mild hybrid system (MHEV) integrates a belt alternator starter (BAS), a lithium-ion battery that provides buffer storage, and a 48/12-volt voltage converter. A compact electric motor, which also uses the compact 48-volt system, accelerates the compressor wheel of the EPC to 65,000 rpm in roughly 300 milliseconds.

New Mercedes-AMG SL 43 features engine with electric exhaust gas turbocharger derived directly from Formula 1

Green Car Congress

Mercedes-AMG presented the SL 43, a technically innovative new entry model for the AMG SL roadster, arriving in US dealerships in summer 2023, starting from $109,900. The turbocharger is operated via the 48-volt electrical system, which also feeds the belt-driven starter-generator (RSG). The AMG SL 43 accelerates from 0 to 60 mph in 4.8

Audi’s mild-hybrid systems: 12V for 4-cylinders, 48V for 6- and 8-cylinders

Green Car Congress

For the four-cylinder engines they are based on the familiar 12-volt electrical system. The six-cylinder and eight-cylinder engines, as well as the W12 cylinder units, will receive a new 48-volt system generally serving as the main vehicle electric system. During slow coasting, the start-stop phase already begins at 22 km/h (14 mph).

Audi gives S5 models their first diesel and 48V MHEV systems; performance and efficiency

Green Car Congress

Both systems are embedded in the standard 48-volt main electrical system. For the first time in the S5 TDI, a powerful 48–volt belt alternator starter is the heart of the mild hybrid system with maximum recuperation power of up to 8 kW. A DC/DC converter steps this voltage down for components in the 12–volt electrical system.
