The displacement of high-wattage loads to more efficient 48 V networks is expected to be the next step in the development of a new generation of mild hybrid vehicles.

SAE International announces its new book, 48-Volt Developments available now on the SAE International website.

Development of higher-voltage electrical systems in vehicles has been slowly progressing over the past few decades. However, tightening vehicle efficiency and emissions regulations and increasing demand for onboard electrical power means that higher voltages, in the form of supplemental 48 V subsystems, may soon be nearing production as the most cost-effective way to meet regulations. The displacement of high-wattage loads to more efficient 48 V networks is expected to be the next step in the development of a new generation of mild hybrid vehicles.

In addition to improved fuel economy and reduced emissions, 48 V systems could potentially save costs on new electrical features and help better address the emerging needs of future drivers. Challenges to 48 V system implementation remain, leading to discussions by experts from leading car makers and suppliers on the need for an international 48 V standard. Initial steps toward a proposed standard have already been taken. So the consensus of global forecasts suggests that 48 V mild hybrids will soon come to dominate the market. Compared with 200-600 V full hybrid and battery electric vehicles, the lower-voltage approach avoids the need for high-cost safety features and large battery packs.

48-Volt Developments inclu des eight technical papers edited by Kevin Jost. Mr. Jost is the Editorial Director for SAE International.

Chapters include:

  • Chapter 1: Fuel Consumption and Emissions Effects in Passenger Car Diesel Engines through the Use of a Belt Starter Generator
  • Chapter 2: Requirements and Protection within a 48V Automotive Wiring System
  • Chapter 3: Mixed Voltages and Aluminum Conductors: Assessing New Electrical Technologies
  • Chapter 4: Hybrid Cars Setting New Challenges for Optimized Power Semiconductors
  • Chapter 5: Specification and Design of a Switched Reluctance 48 V Belt Integrated Starter Generator (B-ISG) for Mild Hybrid Passenger Car Applications
  • Chapter 6: Optimizing Lithium-Ion Batteries – Tailoring Electrodes for Microhybrid Vehicle Applications
  • Chapter 7: Application of 48 Volt for Mild Hybrid Vehicles and High Power Loads
  • Chapter 8: Advantages of a 48 Volt Belt Starter Generator in an Ultra-Light Vehicle Powertrain
