Market Data: Low Voltage Vehicle Electrification

12 V and 48 V Stop-Start Vehicles, Micro- and Mild-Hybrids, and Related Technologies: Global Market Analysis and Forecasts

A combination of factors is pushing the auto industry to reconsider its powertrain production strategies for the next decade with an eye toward more electrification sooner. Increasingly stringent fuel economy and emissions standards are being applied in most global markets—with the possible exception of the US, which is reconsidering its federal standards. New testing methodologies, including the introduction of the World Light Duty Test Protocol (WLTP) and real driving emissions (RDE) tests, imposed in the wake of the Volkswagen diesel scandal will make it even more difficult for OEMs to meet those standards. Meanwhile, several governments in Europe and Asia have proposed bans on traditional internal combustion engines from the 2030s and 2040s onward.

Basic stop-start vehicles (SSVs) have become ubiquitous in many markets, and OEMs are looking to advance beyond that technology. Current systems have reached the limit of practical electrical power availability at 12 V. Efficiency and automation demands can be realized only by increasing the operating voltage, and 48 V is the practical limit to avoid the need for additional safety protection. 48 V 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 57.6 million by 2026, accounting for 54% of all light duty vehicle sales. Of these, about 21% will feature 48 V components.
