High Voltage Auto Systems Coming to a Car Near You
12 V electrical systems in your
car are about to become a thing of the past. With many of the typical car's systems being slated for
electrification, the planned 42 V architecture is needed for ruggedness and efficiency. Drive-by-wire steering and
braking, transmission clutches, variable valve timing, and active suspensions are among the items on the drawing
board now. Exotic schemes are envisioned such as stopping the engine at stop lights or stop signs, then instantly
restarting when the gas pedal is pushed (lower emissions than idling). Higher voltages mean smaller gauges for the
hundreds of feet of wiring in cars, which means less weight, smaller connectors, etc. Analog Devices, Infineon,
and Motorola are among the companies introducing new qualified devices into the market. I wonder if these cars
will qualify as hybrids?
