Market Overview

A 48 Volt battery system is an electric storage solution that runs at a nominal voltage level of 48 Volts. Between the conventional 12V systems and high-voltage electric powertrains, it offers higher power and efficiency without the additional complexity and safety issues of high-voltage configurations. It is largely employed in automotive, industrial, and light electric vehicle applications.

48V battery technology has emerged as a viable option for partial electrification of vehicles. The technology was first introduced in mild hybrid electric vehicles (MHEVs) where it offered the best combination of performance, cost, and safety. By enabling engine start-stop, electric boost, and regenerative braking into vehicles, the 48V technology allows manufacturers to also reduce emissions and increase efficiency while moving away from high-voltage fully electric systems. With its small footprint and reduced safety risk, it makes sense for a much wider variety of low-to-mid power applications.

Analysts' Viewpoint

The growth of the global 48V battery system market is driven by demand for fuel-efficient and low-emission vehicles. To meet global emissions regulations, automakers are looking for affordable options that do not require moving to a high-voltage electric platform. The cost, safety, and small footprint of 48V systems makes them a very good option for mild hybrids, two- and three-wheelers, and light commercial EVs, especially in emerging markets. The expanded use of start-stop systems and regenerative braking is also positively impacting the 48 Volt battery system market.

On the other hand, the most striking observation for the future is how the 48V architecture is fitting a wider range of vehicles, including small electric delivery vehicles, off-road equipment, and even marine systems. Manufacturers are looking for modular and scalable 48V solutions reacting to mobility and industries. The use of lithium-ion batteries and higher-level battery management systems (BMS) is expanding among 48V manufacturers to improve performance, efficiency, and safety.

Many automotive OEMs and battery technology companies are investing heavily in 48V systems. Many OEMs in the developed markets (i.e., Continental, Valeo, Bosch, and Mahle) are now introducing integrated 48V mild hybrid technologies, and there is a myriad of players in regional markets, particularly India and Southeast Asia who are adopting the architecture for electric scooters, electric rickshaws, and small EVs. Collaborations between component makers and start-up EV companies are also multiplying to expedite innovation and localization and therefore broaden the adoption of 48V technology.

Recent Developments (2024-2025)

• In June 2025, SAE International published a comprehensive article discussing the increasing trend to migrate away from traditional 12V vehicle architectures to advanced 48V zonal power systems. OEMs are quickly transitioning to 48V systems to meet the increasing power demands from modern vehicles' ADAS, infotainment, and comfort features, and the added benefits of 48V systems such as increasing efficiency, lower weight, and lower current draw. In addition, the report highlights how the OEMs are leveraging the benefits from the much lighter weight and electrical efficiency potential from adopting 48V architectures, which allows automakers to reduce wire harness weight significantly up to 80% - and design efficiencies through smaller, lighter components. The article also emphasizes that 48V is not just for EVs; OEMs are deploying 48V systems in ICE and hybrid vehicles, as well, in order to address and overcome limitations posed by 12V alternators. Alternatives such as 48V zonal architectures, and advances in miniaturized DC-DC converters, these technologies are enabling OEMs to implement a phased approach to the transformation to 48V, so they can scale their adoption of zonal architecture associated with a particular vehicle based on available engineering capabilities and validation timing.

• In December 2024, Valeo revealed its 48V mild hybrid system, a more economical and higher efficient way to electrify glovebox solutions for a myriad of vehicles. These solutions are set to contribute to global CO2 reduction targets. Valeo will deliver two tiers of hybridization; one standard or low cost, fuel savings and torque assist, and the second is an enabling tier which will allow 100% electric propulsion. Valeo's 48V design saves approximately 20% on costs compared to traditional high-voltage hybrids by optimizing the architecture with minimal safety preservation rules. Valeo also produced the first ever 48V plug-in hybrid vehicles with electric ranges of 80 km, as well as a 100% electric 48V prototype designed to "radically rethink urban mobility at lower cost and easier charging." They also used an alternative charging model for their first deployment which they did in the Citroën AMI.
