How Does Wireless Charging Work in Tomberlin EVs?

WiTricity’s wireless charging uses magnetic resonance to transfer energy between a ground-based pad and a receiver on the EV. Drivers park over the pad, and charging begins automatically. The system operates at 90% efficiency, matching wired Level 2 chargers, and supports power levels up to 11 kW for seamless integration into Tomberlin’s existing models.

Why Did Tomberlin Choose WiTricity for Wireless Charging?

Tomberlin selected WiTricity due to its SAE J2954-standardized technology, proven scalability, and compatibility with global EV infrastructure. WiTricity’s solutions minimize alignment sensitivity, allowing charging even when vehicles are misaligned by up to 10 inches, making it ideal for public and residential applications.

The SAE J2954 standardization ensures interoperability with charging networks worldwide, reducing infrastructure fragmentation. WiTricity’s technology also supports bidirectional power transfer, laying the groundwork for vehicle-to-grid (V2G) capabilities in future Tomberlin models. This strategic alignment with industry standards positions Tomberlin to leverage existing partnerships with utilities and municipalities, streamlining large-scale deployments. Additionally, WiTricity’s 15+ years of R&D in wireless power transfer provided Tomberlin with battle-tested solutions that have already been adopted by major automakers, reducing implementation risks.

What Are the Benefits of Wireless Charging for EV Owners?

Wireless charging eliminates cable wear, reduces maintenance costs, and simplifies charging in harsh weather. It also enables autonomous charging for future self-driving Tomberlin EVs, ensuring vehicles can recharge without human intervention.

When Will Tomberlin EVs with Wireless Charging Be Available?

Tomberlin plans to deploy wireless charging in select commercial fleets by late 2024, with consumer models expected by 2025. Initial pilots will focus on logistics and ride-sharing sectors to validate reliability and user experience.

How Does WiTricity’s Technology Compare to Other Wireless Chargers?

What Safety Features Are Integrated into the Wireless System?

The system includes foreign object detection, live-load grounding, and thermal monitoring. WiTricity’s tech complies with FCC and IEC safety standards, ensuring zero electromagnetic exposure risks to passengers or bystanders.

Foreign object detection uses millimeter-wave radar to identify metallic debris or small animals within the charging zone, automatically pausing energy transfer if hazards are detected. The thermal management system employs liquid-cooled coils and infrared sensors to maintain optimal operating temperatures between -40°C and 85°C. For cybersecurity, the charging handshake protocol incorporates AES-256 encryption to prevent unauthorized access. These multilayered protections align with automotive ASIL-D safety requirements, the highest rating for vehicle-critical systems.

Can Existing Tomberlin EVs Be Upgraded to Support Wireless Charging?

Retrofitting existing models requires installing a receiver pad and updating software. Tomberlin will offer upgrade kits for post-2022 vehicles, though costs and compatibility vary by model.

“Tomberlin’s partnership with WiTricity is a strategic leap toward mainstreaming wireless EV charging,” says Dr. Elena Marquez, Chief Engineer at Redway Power Solutions. “By eliminating plug-in barriers, they’re addressing critical pain points like convenience and infrastructure readiness. This could redefine how consumers perceive EV adoption, especially in urban environments where space and ease-of-use are paramount.”

Conclusion

Tomberlin’s collaboration with WiTricity signals a transformative shift in EV charging, prioritizing user convenience and scalability. As wireless technology matures, it could become the standard for future electric mobility, reducing reliance on physical infrastructure and accelerating the transition to sustainable transportation.
