Mercedes-Benz is redefining electric mobility with its ELF – Experimental Charging Vehicle – a mobile testbed for the next generation of charging technologies. Standing for Experimental-Lade-Fahrzeug in German, ELF represents the brand’s bold vision for a sustainable, efficient and intelligent charging future.
Mercedes-Benz ELF 2025: a novel approach to charging electric vehicles
Electric mobility is about more than zero local emissions; it’s about integrating innovation, responsibility and renewable energy. Mercedes-Benz is extending this approach beyond its vehicles through intelligent home, workplace and public charging solutions, backed by its MB.CHARGE ecosystem and pioneering Plug & Charge function.
Ultra-Fast and Intelligent Charging
At the heart of ELF lies research into fast charging at megawatt levels, exploring the limits of what’s technically possible. The vehicle features both MCS (Megawatt Charging System) and CCS (Combined Charging System) connectors, achieving capacities of up to 900 kW – enough to add 100 kWh in just 10 minutes.
This dual system helps Mercedes-Benz test future technologies while refining today’s charging experience. Learnings from ELF directly influence production vehicles such as the CONCEPT AMG GT XX, capable of adding around 400 km of range in five minutes.
Together with Alpitronic, Mercedes-Benz has also developed a prototype high-performance charging station capable of delivering 1,000 amps through a CCS cable, paving the way for faster, more convenient charging in future Mercedes-Benz charging parks.
Bidirectional Power and Energy Management
ELF also explores bidirectional charging – allowing energy to flow both to and from the vehicle. This enables Vehicle-to-Home (V2H), Vehicle-to-Grid (V2G) and Vehicle-to-Load (V2L) capabilities, turning EVs into mobile energy storage units.
The technology promises energy cost savings, greater self-sufficiency, and enhanced grid stability. Mercedes-Benz plans to launch its first bidirectional services in Germany, France and the UK from 2026 through MB.CHARGE Home, combining vehicles, wallboxes, and renewable energy tariffs.

Wireless and Automated Charging
ELF also tests inductive (wireless) and conductive (underfloor) charging, offering hands-free convenience ideal for homes, fleets and compact urban environments. Both systems deliver up to 11 kW AC, providing everyday practicality without manual cable connection.
Looking further ahead, robotic charging systems are under development to automate the process entirely – enhancing accessibility and efficiency, particularly for fleet and high-power applications.
Driving a Connected, Sustainable Future
From ultra-fast charging to bidirectional energy sharing and wireless solutions, Mercedes-Benz’s ELF demonstrates a holistic approach to sustainable mobility. By merging research, innovation and real-world application, the company continues to shape the future of electric transport — making charging faster, smarter and greener.
