A hybrid system of 48V is termed a mild hybrid. It combines an electric motor with a conventional combustion engine, resulting in an average 10% reduction in fuel consumption and carbon dioxide (CO2) emissions. This is made possible through braking energy recuperation and start-stop coasting. In the latter case, the combustion engine completely turns off, not only when idle, but also when the vehicle is being driven if neither the gas nor the brake pedal is engaged.

Implementing a higher voltage power layer (high than 12V) in vehicles is not a new phenomenon. However, with respect to 48V, there is a certain amount of hesitation. About 15 years ago, the industry was on the verge of implementing 42V electrical systems, but the technology did not catch owing to a couple of reasons. Firstly, alternators were given a new lease of life and increased their output by being liquid cooled. Secondly, some 42V components, such as headlamp bulbs, were not able to meet vibration tests. In the case of bulbs, the filaments were too fine and delicate. At that time, it appeared that alternators had reached a power limit, and there was the possibility of more than halving the weight of wiring harnesses, which by then had become bloated because of the growing options list of powered devices.

Today, the reasons for implementing 48V are quite different. Contrary to the implementation plans for 42V more than a decade ago, vehicle manufacturers propose a dual-loop network approach for the implementation of 48V. However, although a defacto standard has been set by German premium vehicle manufacturers, a widespread adoption is only beginning to materialize.
