VS - Electrical Systems From Stop-Start to Hybridization

To more energy recovery with i-StARS Gen3 Higher regenerative capabilities allows to support the engine in numerous situations, as in some torque assist phases or pure takeoff events, they require new electrical machines, new storage packs and a change in electrical architectures. Valeo i-StARS Gen3 is able to recover up to 4kW@4000rpm@15v for several minutes, enabling some comfortable assistance for electric actuators (Eg. Valeo E-charger) or pure torque assistance via the belt drive.
