OEMs are looking for various means to reduce the CO2 emissions required for 2020 and 2025. The 12v power-net can no longer sustain the electrical load that present day top-end vehicles use. Any new addition to the electrical load will require an increase to the power-net capacity, so OEMs are considering migrating to a 48v power-net thereby using 2 voltages. The 48v power-net also manages to reduce vehicle weight, thereby reducing fuel consumption and CO2 emissions. Heavy-duty functions are expected to port to the new 48v power-net. This study investigates the current and future market for 48v power-net in the passenger vehicle market including adoption challenges. The study period is 2014 to 2025 while the forecast period is 2017 to 2025.
