Rheinmetall, the German technology group, has signed a high-value supply contract with a major North American truck manufacturer to provide high-voltage coolant pumps for battery-electric medium- and heavy-duty vehicles. The double-digit million-euro agreement will see Rheinmetall deliver a mid-six-figure volume of its CWA 2000 coolant pumps starting in 2028, with deliveries set to continue through 2035.
The contract underscores Rheinmetall’s growing presence in the e-mobility sector, as commercial vehicle manufacturers scale up electrification strategies. The unnamed customer, described only as a “renowned” player in the North American truck market, selected Rheinmetall’s CWA 2000 system based on its advanced technical profile and compatibility with both battery-electric and fuel cell vehicle architectures.
According to the company, the CWA 2000 is engineered for the HV3b voltage class and operates at voltages up to 850 volts. Designed to meet a range of thermal management requirements, it is adaptable for various cooling configurations in next-generation electric vehicles. “The CWA 2000 is a versatile solution for a wide range of cooling specifications,” Rheinmetall stated, citing its suitability for both BEVs and FCEVs, and its robust lifecycle performance.
The system also incorporates key safety features. It supports both active and passive high-voltage interlock loops (HVIL), which maintain operational readiness while ensuring safety. If the HVIL is broken, the system immediately cuts off power, protecting service personnel and vehicle operators from accidental exposure to high-voltage currents during the vehicle’s lifecycle.
Rheinmetall has been expanding its e-mobility offerings, having introduced a modular EV heat pump in mid-2023 and announcing its first customer through a joint venture with U.S.-based Polycharge shortly before that. The new contract further positions the company as a critical supplier in the commercial EV transition.
