FORVIA HELLA and Tau Motors Collaborate on Innovative EV Charging Solutions

Transforming Electric Vehicle Charging: A New Era with FORVIA HELLA and Tau Motors

In the ever-evolving landscape of electric vehicles (EVs), two industry leaders, FORVIA HELLA and Tau Motors, have embarked on a pioneering partnership that seeks to reshape the future of EV charging solutions. Announced on September 2, 2025, this collaboration focuses on creating an innovative component known as the Virtually Isolated Onboard Charger (viOBC).

What is the Virtually Isolated Onboard Charger (viOBC)?

The viOBC represents a significant leap forward in charging technology for electric vehicles. This charger is designed with advanced features that enhance both power density and energy efficiency. Notably, the viOBC eliminates the need for a traditional transformer, which is often a bulky and heavy component in conventional chargers. This innovative design allows for a dramatic reduction in both the size and weight of the charger, making it a more attractive option for vehicle manufacturers.

The remarkable outcomes of this development include:
1. High Power Density and Efficiency: The viOBC can achieve up to 7 kW per liter of installation volume, optimizing power delivery without compromising safety or functionality.
2. Reduced Size and Weight: By eliminating the transformer, the required installation space is halved, and the overall weight of the unit is reduced by approximately one-third.
3. Increased Energy Efficiency: The transformerless design boasts an energy efficiency rating of over 98% during the charging process, translating into cost savings for EV users due to lower electricity consumption.

Strategic Partnership under HELLA Ventures

FORVIA HELLA, recognized for its expertise in high-voltage and power electronics, joins forces with Tau Motors, known for its software-defined technology platform. This partnership also includes an investment in Tau through HELLA Ventures, highlighting the commitment both companies have towards advancing EV technology. Wesley Pennington, the Founder and CEO of Tau, expressed pride in collaborating with FORVIA HELLA, emphasizing the synergy created by combining Tau's innovative platform with FORVIA HELLA's extensive experience in the automotive sector.

Advanced Functionality for the Future of Mobility

The viOBC not only serves as a charging solution but also supports advanced energy management features, including vehicle-to-grid integration. This capability allows EVs to serve not only as modes of transportation but also as potential energy resources for homes and the wider electrical grid. This dual functionality is critical in moving towards a sustainably electrified future where EVs can contribute to grid stability and energy distribution.

Testing and Production Timeline

With a successful technological and commercial concept testing phase already completed, the series production of the viOBC is projected to commence within the next two to three years. This timeline reflects the commitment of both companies to bringing transformative products to the market swiftly and efficiently, meeting the advancing demands of the electric vehicle sector.

In essence, the partnership between FORVIA HELLA and Tau Motors is a significant step towards enhancing electric vehicle charging capabilities. By combining innovative technology with industrial excellence, this collaboration represents a forward-thinking approach to sustainable mobility, setting the stage for a cleaner and more efficient future in transportation.
