48V Electrical Architecture Market Report
Implementing a higher voltage power layer in vehicles is not a new phenomenon. However, with respect to 48V, there is a certain amount of hesitation, as some 15 years ago the industry was on the verge of implementing 42V electrical systems, but the technology did not catch due 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 the bulbs, the filaments were too fine and delicate. At the time, it appeared that alternators had reached a power limit and there was the possibility of more than halving the weight of wiring harnesses that by then had become bloated due to 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 the German premium vehicle manufacturers, a widespread adoption has yet to materialise.
This report looks at 48V implementation in two major areas: mild-hybrids and non-hybrid applications such as electric turbocharger.
