Opportunity Snapshot

AutomotiveE 48V System Market Growth Drivers and Impact Analysis

Emission Compliance and Affordable Hybridization

In addition to achieving efficiency gains from combustion engines in the short term, automakers must balance their increased costs against the higher prices of fully hybrid or all-electric powertrain technology. By using a 48V system, this represents an effective compromise that allows for regenerative braking, engine off-coasting, improved start-stop performance, and electrical boost. The significance of this solution lies in the ability of manufacturers to incorporate mild hybrid technologies within existing vehicles without major platform changes.

Rising Electrical Loads in Modern Vehicles

These functions necessitate a stable energy supply for the advanced driver assistance system, infotainment, thermic, electric compressor, and chassis systems. The current 12-volt electrical architecture will have inefficiencies and wiring limitations due to the increase in loads. A 48V system helps in reducing current and enables higher power devices. The current driver increases load from fuel efficiency to comfort, safety, and performance functions that have become standards in the mid, premium, and luxury vehicle segments.

Supplier Innovation in Integrated Modules

The supplier components of these systems are working to produce starter generators, DC-DC converters, 48V batteries, eAxles, and power electronics that are easier to integrate into the vehicle. This modular design makes the engineering process much simpler for the OEM and is scalable within different regional platforms. Once these parts have been tested on a larger scale, vehicle manufacturers will be able to develop their product faster and use the same design across multiple vehicles.

AutomotiveE 48V System Market Future Trends

Software-Managed Energy Optimization

Future automotive 48V system market trends will center on smarter energy management rather than hardware alone. The software controlling the system will help determine whether the energy should be recovered, torque enhanced, accessory loads supported, or the engine loads should be reduced based on various parameters like the journey, driving style, battery status, and thermals. This will result in better efficiencies and enhance the value of the 48V system in smart vehicles.

Expansion Beyond Basic Mild Hybrid Functions

The application of 48V systems is shifting from simple BS/G to electric compressor, chassis control, and rear eAxle. This will help increase revenues as the same voltage system can be used for both propulsive assistance and auxiliary electrical systems. The premium vehicles will feature advanced systems, while affordable vehicles will incorporate the simpler systems at reduced cost.

AutomotiveE 48V System Market Opportunities

Platform Standardization Across Vehicle Classes

There is potential for automakers to realize substantial gains through 48V architecture standardization in entry-level, mid-range, premium, and luxury vehicles. Standardization of the electrical architecture will enable the reuse of converters, batteries, wiring, and control systems, while adjusting the amount of electrical power according to the vehicle segment. There are significant benefits for automakers from a global perspective that need a flexible transitional solution to meet regional emission requirements.

Localized Supply Chains for High-Growth Regions

48V component production at the regional level would help ensure cost control, logistics security, and quick launch of the program by OEMs. Asia Pacific is a region with the greatest possibility for scaling due to China, Japan, South Korea, and India combining production volumes with increasing efficiency demands.
