It’s directly connected to the engine via the drive belt, which makes it super efficient and means that the engine can restart very quickly and smoothly. When you're accelerating, the BISG acts as a motor, providing extra torque to the engine to help it out. When you're braking or coasting, it acts as a generator, converting kinetic energy into electricity, which is then stored in the 48V battery. The BISG also handles the start-stop function, restarting the engine seamlessly when you lift your foot off the brake pedal. This start-stop functionality helps save fuel, especially in city driving. The BISG is one of the most important components in the system, playing a key role in improving both efficiency and emissions.

Finally, we have the DC/DC Converter. This device is a critical part of the system's management, acting as the intermediary between the 48V system and the car's standard 12V electrical system. The car's electronics, such as the lights, infotainment system, and other accessories, require 12V to operate. The DC/DC converter takes the high-voltage (48V) from the hybrid battery and converts it to the lower voltage (12V) that these components need. It ensures that the car's systems run smoothly, without any voltage fluctuations or failures. The DC/DC converter also helps to distribute the power throughout the vehicle, ensuring that all electrical components get the power they need, when they need it. The converter is an integral part of the 48V system that helps the entire hybrid system to function correctly. Without it, the car's traditional electrical systems wouldn't work, and the benefits of the hybrid system would be lost.
