The e4Boost Powertrain System, Electric Supercharger 48V
The 48V e4Boost powertrain system simultaneously enhances engine performance and reduces fuel consumption and CO2 emissions. The e4Boost solution, composed of an Electric Supercharger 48V and a Belt Starter Generator iBSG 48V, recovers a maximum amount of braking energy and stores it in a 48V battery.

The Valeo e4Boost 48V Powertrain System, the electric supercharger, unlike turbochargers powered by exhaust gases, is driven by an electric motor, using switch reluctance technology, resulting in almost zero lag (250 milliseconds).
This system can be applied across all vehicle segments, to both gasoline and diesel engine models, recovers a maximum amount of braking energy and stores it in a 48V battery for various uses, such as gives the engine more torque,boost engine performance during in-gear acceleration,optimize vehicle energy management.
