Less than 50 years ago there were virtually no electronics in the car. Today electronic systems are driving a revolution in how we interact with our car but also enabling its electrification. Whether it is plug-in hybrid electric vehicles (PHEV) or full battery electric vehicles (BEV), the need to charge the battery, manage power requirements and drive traction motors are the same. And while 48 V plays a key role, most systems are moving to either 400 or 800 V batteries requiring greater innovation in high-power wide bandgap semiconductors.

One of the biggest improvements that electronic systems have brought is an improvement in automotive chassis and safety systems. Whether it is replacing heavy mechanical systems with lightweight electronics – with the additional benefit of reducing CO2 emissions – to dedicated systems to enhance driver and passenger safety, today’s vehicles are radically different. To further enhance safety many of these systems need to offer system level redundancy, significantly increasing the silicon content.

While the focus of electrification is often seen to be the powertrain, it is also changing traditional body control and lighting applications. The rise of LED lighting not only gives designers efficient interior and exterior lighting options, but also opens the door to changing the overall look of a vehicle. In addition, any pumps and motors – from heating and ventilation to powered seat, door, window and mirror control – makes changes inside the cabin just as dramatic as under the hood.
