Many regions around the world will implement higher fuel efficiency standards in 2020 and beyond. As a result, vehicle manufacturers are investing in new technology now so that their fleet will be compliant and they will avoid punitive fines. Yet, only the smallest vehicles will be able to meet the new standards through incremental improvements. Implementing a full hybrid drive system would be one solution for larger vehicles, but the incremental costs necessary would be prohibitive. Low voltage electrification offers a practical alternative. Basic stop-start vehicles (SSVs) have made progress in reducing fuel consumption, but systems have reached the limit of practical electrical power availability at 12V. Greater fuel efficiency as well as increasing levels of automation can be realized only by increasing the operating voltage, and 48V is the practical limit to avoid the need for additional safety protection. 48V stop-start systems will combine with other technologies, including micro and mild hybrid capabilities and electric turbochargers, to increase efficiency without the adoption of full hybrid or plug-in electric capability. According to Navigant Research, global sales of light duty SSVs will exceed 61 million by 2025, accounting for 59% of all light duty vehicle sales. Of these, about 15% will feature 48V components. This Navigant Research report analyzes the global market for low voltage electrification opportunities and challenges. The study provides an overview of the market issues associated with improving light duty vehicle efficiency and the technologies that are likely to reach production. Global market forecasts for vehicle sales and the value of key components, segmented by global region, extend through 2025. The report also examines the key 48V components related to low voltage vehicle electrification, as well as the competitive landscape.
