    48V Hybrid battery system functions

    • Mild Hybrid Operation: A 48V system supplements the ICE with an electric motor that can provide assistance during acceleration, regenerative braking, and power to auxiliary systems.
    • Start-Stop Technology: The system enables efficient start-stop functionality, shutting off the engine during idling and restarting it seamlessly when needed.
    • Regenerative Braking: Captures energy during braking and deceleration, storing it in the 48V battery for later use.


    • Start-Stop Systems: Automatically shuts off the engine when the vehicle is stationary and restarts it when needed, reducing idling time and fuel consumption.
    • E-Boost: Provides additional torque during acceleration, enhancing vehicle performance.
    • Electric Turbochargers and Superchargers: Improves engine response by reducing turbo lag and providing instant power boost.
