The Schaeffler division is making two additional Vitesco repair solutions available to the independent aftermarket: a Voltage Stabilization System (VSS) for micro hybrid vehicles from PSA and Toyota, and a 48V DC/DC converter for mild hybrid vehicles from Ford.

During the engine start process, the capacitors release energy stored while driving within a very short time, compensating for the high-power demand. Starting the engine via a starter-generator requires a comparatively high amount of energy.
If this energy is drawn solely from the conventional 12-volt electrical system, the voltage can briefly drop by several volts, causing visible flickering of the vehicle’s lighting and electronic displays. Schaeffler said that by stabilizing the voltage supply, the capacitors ensure smooth engine restarting and contribute to longer battery life, improved driving comfort and compliance with current emissions standards.

Schaeffler Vitesco 48V DC/DC Converter: Efficient Energy Management
The Schaeffler Vitesco 48V DC/DC converter, available in May, is used in mild-hybrid vehicles equipped with a 48V starter generator and an additional battery to enable more efficient power delivery and boost performance during acceleration. The converter links the vehicle’s 48-volt electrical system with the 12-volt onboard electronics, ensuring stable voltage levels and preventing energy losses.
The converter is a component of energy management in mild-hybrid vehicles and for achieving type-approval compliant CO2 emissions. Its bidirectional design allows 12-volt components to be supplied from the 48-volt network while charging the starter battery. Conversely, in the event of a temporary failure, the 48-volt system can also draw energy from the 12-volt network.

Significant Potential for the Aftermarket
Until now, both the Schaeffler Vitesco Voltage Stabilization System and the Schaeffler Vitesco 48V DC/DC converter were available exclusively as original equipment components. This is a further expansion of the portfolio to include OE-quality Vitesco products.
These technologies have been installed in large numbers of vehicles worldwide for many years. The Schaeffler Vitesco Voltage Stabilization System enables a 1:1 replacement in approximately 2.7 million vehicles worldwide from PSA and Toyota.

“By integrating Vitesco products, we are expanding our portfolio for electrified vehicles,” said Stephan Niese, director, global product management, E-Mobility, at Schaeffler Vehicle Lifetime Solutions. “In this way, we help the aftermarket unlock the potential of e‑mobility and enable workshops to offer their customers professional, future‑ready and profitable vehicle service.”
