Mercedes-Benz introduced an all-in-one mobile EV charging machine, “ELF,” that promises to unlock charging speeds as quick as filling up at the pump.
Mercedes-Benz unveils the ELF mobile EV charging van
It may look like an electric van, but Mercedes-Benz claims ELF is much more than just any ordinary vehicle. It’s “a symbol of a bold new era in charging,” the luxury brand said on Thursday.
The nickname comes from the German term Experimental-Lade-Fahrzeug (ELF), which translates to Experimental Charging Vehicle.
The Mercedes-Benz ELF is an all-in-one mobile EV powerhouse that combines ultra-fast, bidirectional, inductive, and conductive charging. It’s based on the Mercedes V-Class people carrier and is equipped with five unique charging ports.
It will act as a rolling test lab, promising to unlock faster, more convenient, and sustainable electric vehicle charging.
The ELF features two fast charging systems: A standard Combined Charging System (CCS) and a heavy-duty Megawatt Charging System (MCS).
Mercedes is “testing the limits of CCS,” claiming the ELF can achieve a charging capacity of up to 900 kW, or enough to add 100 kWh in about 10 minutes. The MCS system, on the other hand, was initially developed for heavy-duty electric trucks, which Mercedes says unlocks charging capacities in the megawatt range.
The company is already using the all-in-one mobile EV charging rig to improve charging on its upcoming vehicles.
For example, the Concept AMG GT XX hit a peak charging power of 1,041 kW during megawatt charging after its record-breaking run in Nardò in August.
Mercedes collaborated with Alpitronic to develop a high-performance EV charging station capable of delivering up to 1,000 amps through a modified CCS commercial truck charger. The company is now using what it has learned to develop a new generation of ultra-fast chargers for use at Mercedes-Benz parks.
According to Mercedes, the new chargers will deliver speeds “that differ only minimally from the conventional refuelling process.”
The ELF is not only capable of absorbing electricity, but Mercedes-Benz is using it to its full potential with bidirectional charging capabilities.
Capable of both AC and DC bidirectional charging, the ELF can feed energy into your home (Vehicle-to-Home/ V2H), the grid (Vehicle-to-Grid/ V2G), or electric devices (Vehicle-to-Load/ V2L).
Mercedes said a typical vehicle battery with a capacity of 70-100 kWh can power an average single-family home for two to four days.
The new electric CLA and GLC with EQ Technology are the first Mercedes vehicles that offer bidirectional charging capabilities. In 2026, the automaker will launch its first services for bidirectional charging in Germany, France, and the UK. Other markets are set to follow shortly after.
In combination with intelligent energy management, Mercedes said electricity costs can be significantly reduced. Depending on energy use, homeowners can save about 500 euros ($580) per year.
Mercedes-Benz is also using the ELF to test other charging methods, including cable-free induction and automated conductive charging.
The learnings from the ELF will be key to unlocking faster, more convenient, and sustainable charging for upcoming Mercedes-Benz EV models.
