Electrification strategy: Rheinmetall sets up joint venture for e-mobility and green energy with US specialist

Known as Rheinmetall PolyCharge GmbH, the new joint venture company is majority-owned by Rheinmetall (75%). The remaining 25% stake is held by PolyCharge. In this constellation, Rheinmetall is responding to growing demand for e-mobility and green energy components, especially in the automotive parts sector but also from its military customers.

In the Rheinmetall PowerPack system for electrically powered vehicles, now in development, advanced DC-link capacitors from PolyCharge play an important role. Owing to its improved efficiency and range, Rheinmetall sees strong market potential and scope for growth for the new power pack solution.

In this close operational partnership with PolyCharge, the joint venture will have exclusive rights to produce and market NanoLam capacitors in Europe.

To underpin its close cooperation with PolyCharge, Rheinmetall has simultaneously taken up an approximately 13% share in the Tucson, Arizona-based company. Both parties have agreed not to disclose the financial dimensions of the transaction.

“The founding of this joint venture marks another important step in our transformation strategy, enabling us to offer our customers in the automotive and industrial sector top electrification technology as we move forward”, stated Rene Gansauge, chief executive of Rheinmetall’s Sensors and Actuators division. “Advanced NanoLam technology lets us offer a product that’s substantially smaller and lighter than the conventional solutions, and which can operate at higher temperatures. This is a clear technological advantage, assuring that Rheinmetall PolyCharge is well positioned to meet the growing demand for these technologies.”

“Diversifying PolyCharge’s manufacturing base is crucial as we transition to high-volume production of NanoLam capacitors for automotive, aerospace, and industrial markets,” said Steven Yializis, chief operating officer of PolyCharge America. “Rheinmetall’s technical depth, application expertise, and strong presence in Europe make it an ideal partner, allowing for rapid expansion in this important and growing market,” added Mr. Yializis.

The new PolyCharge capacitors with nanolaminate technology feature sub-micrometre-thin, dielectric polymer coatings that enable optimum cooling and improved performance.

PolyCharge is a technologically leading supplier of these components, whose chief advantages are thermal stability, longevity and high output density.

In future, the activities of the majority joint venture will be domiciled in Rheinmetall’s Sensor and Actuators division, which is spearheading the company’s electrification strategy and now implementing advanced developments in the “Beyond Automotive” and industrial domain.
