REPT BATTERO and Germany’s Haller Group Sign European Battery Partnership

REPT BATTERO and Germany’s Andreas Haller Holding GmbH have signed a strategic memorandum of understanding aimed at expanding battery use in Europe’s zero-emission commercial-vehicle and energy-storage markets. The companies announced the agreement during IAA Transportation 2026 in Hanover, setting a target of 1 GWh of battery volume per year in Europe by 2030.

The target covers batteries for trucks, buses and battery energy storage systems, or BESS. One gigawatt-hour equals 1,000 megawatt-hours of battery capacity, making the 2030 figure a scale target for annual battery volume rather than a disclosed contract value. The announcement does not provide pricing, a binding purchase order, customer commitments or a year-by-year delivery schedule.

The MOU pairs battery supply with Haller’s European platform

REPT BATTERO said in its IAA 2026 announcement that the MOU is intended to combine its battery technology with Haller Group’s European localization and service capabilities. The stated scope reaches beyond new electric trucks because Haller’s operations span new vehicles, fleet conversions, battery systems, infrastructure and after-sales support.

Haller’s commercial-vehicle portfolio includes QUANTRON, which focuses on new battery-electric and hydrogen commercial vehicles, and pepper, which specializes in converting existing bus and commercial-vehicle fleets using modular battery and hydrogen systems. That gives the partnership potential routes into both newly built vehicles and the retrofit market instead of limiting it to one vehicle platform.

Battery systems are another part of Haller’s existing business. Haller Technology says it develops customized solutions from 48 volts to 800 volts, supplying components from cells through finished battery systems for mobile and stationary applications. It also works on charging infrastructure and photovoltaic systems. That mix aligns with the MOU’s inclusion of stationary energy storage alongside trucks and buses.

The German group traces its history to a carriage business founded in Augsburg in 1882 and is now led by the fifth generation of the Haller family. Its current zero-emission structure is much newer: Haller says QUANTRON was founded in 2019, Haller Technology followed in 2022, and the group acquired Quantron assets in 2025 as it built out a broader commercial-vehicle platform.

REPT is bringing a multi-format commercial battery lineup to Europe

The partnership announcement came as REPT BATTERO displayed a four-generation battery-pack lineup at IAA Transportation. The company positioned the range for several commercial-vehicle operating patterns rather than a single standardized truck architecture, with capacities spanning lighter applications through long-haul configurations.

Its Chassis D Pro system is listed at 600 to 800 kWh and uses an 800-volt architecture. REPT says the platform can support charging power from 750 kW to 1,300 kW and is designed around long-distance heavy-duty operation. The company also showed an F-Pack series configurable from 400 to 675 kWh, while its C-Pack and G-Pack products cover 140 to 568 kWh for uses that include buses, special-purpose vehicles, mining trucks and construction machinery.

Those products help explain why the 1 GWh target is expressed as battery volume rather than a specific vehicle count. Battery requirements can vary sharply across a city bus, a converted commercial vehicle, a long-haul tractor and a stationary storage installation. The MOU therefore leaves room for Haller to apply REPT systems across several businesses while future commercial agreements determine the actual mix.

REPT’s release also says its Chassis D Pro is designed for 600 to 700 kilometers of range and a full recharge within a 45-minute driver rest period. Those are company-stated performance claims tied to specified operating conditions and charging capability, not independent test results. The more consequential point for the partnership is that REPT is presenting battery systems at the capacities and voltage levels used in heavy commercial vehicles, while Haller already operates in the European truck, bus and stationary-storage markets.

The 2030 volume target still requires later commercial execution

IAA Transportation 2026 ran in Hanover from Sept. 15 through Sept. 20, following a press day on Sept. 14. The event centers on commercial vehicles, logistics and transport technology, making it a natural venue for a battery supplier and a European commercial-vehicle group to announce a cooperation framework.

The MOU establishes an intended direction and a 2030 scale objective, but it is not the same thing as a disclosed multiyear supply contract. REPT and Haller did not announce an initial order size, battery pricing, a European production location or interim annual targets in the materials reviewed by MarketReview. They also did not specify how much of the planned 1 GWh annual volume would go to trucks and buses versus stationary storage.

That leaves the next material developments to be commercial ones. Firm supply orders, named vehicle programs, localization decisions or intermediate volume commitments would show how the companies intend to move from the current framework toward the 1 GWh annual target. For now, the agreement gives REPT a stated route into Haller’s European zero-emission ecosystem and gives Haller access to a broader set of battery-pack formats as it expands new-vehicle, conversion and energy-storage offerings.
