Ovar Tech Integrated Chargers: Ideal Applications for 6.6kW OBC + 1.5/2kW DC-DC and Bi-directional 11kW + 3kW Solutions

Ovar Tech’s integrated charging systems, such as the 6.6kW OBC + 1.5/2kW DC-DC and the bi-directional 11kW OBC + 3kW DC-DC modules, are best suited for commercial vehicles, industrial machinery, specialty EVs, and marine applications. These compact 2-in-1 solutions combine onboard charging and auxiliary power conversion in a single unit, delivering significant advantages in weight, space, cost, and system reliability compared to discrete components.

Why Integrated OBC + DC-DC Solutions Excel

Integrated chargers reduce wiring complexity, minimize weight by 20-35%, shrink volume by 25-40%, and simplify thermal management by sharing a common housing and cooling system. They also improve overall system efficiency and EMC performance.

Ovar Tech offers both unidirectional and bi-directional variants, supporting voltage platforms from 48V to 800V on the high-voltage side and stable 12V/24V low-voltage output — ideal for modern electrified platforms.

Key Application Scenarios

1. Commercial Vehicle Fleets (Delivery Vans, Buses, and Trucks)

Urban delivery fleets and public transit buses require fast, reliable charging and robust low-voltage power for auxiliary systems (air conditioning, lighting, telematics). Ovar Tech’s 6.6kW OBC + 1.5/2kW DC-DC integrated unit provides efficient AC charging while simultaneously powering 12V/24V systems. Its compact design fits easily into space-constrained chassis, reducing overall vehicle weight and improving energy efficiency.

2. Industrial and Construction Machinery

Forklifts, aerial work platforms, and heavy-duty material handling equipment operate in harsh environments with high vibration and dust. The rugged, automotive-grade design of Ovar Tech’s integrated modules (IP67/IP69K protection) ensures reliable performance. The integrated architecture minimizes failure points and simplifies maintenance in fleet operations.

3. Marine and Yacht Applications

Yachts and electric boats demand corrosion-resistant, vibration-proof, and highly reliable power electronics. Ovar Tech’s bi-directional 11kW OBC + 3kW DC-DC is particularly valuable here, supporting Vehicle-to-Load (V2L) and potential shore power integration. The module can charge the main battery from shore power or generators while powering onboard 12V/24V systems for navigation, lighting, and appliances.

4. Specialty and Conversion Vehicles

Ambulances, recreational vehicles (RVs), and custom electric conversions benefit greatly from integrated solutions. The reduced weight and simplified installation lower conversion costs and improve vehicle dynamics. Bi-directional capability in the 11kW + 3kW model enables emergency power export, useful for mobile medical or rescue operations.

5. Fleet Electrification and Depot Charging

For operators transitioning large fleets to electric, Ovar Tech’s integrated chargers offer excellent scalability. The shared thermal design allows consistent performance during frequent charging cycles, while bi-directional functionality supports future smart grid and Vehicle-to-Grid (V2G) applications.

Ovar Tech Product Advantages

Ovar Tech’s integrated charging machines stand out due to:

• High Power Density: Compact footprint for easy vehicle integration
• Advanced Topologies: CLLC resonant design for high efficiency (up to 95%)
• Robust Thermal Management: Air-cooled or liquid-cooled options available
• Full Automotive Compliance: AEC-Q, ISO 26262 functional safety, and strong EMI performance
• Bi-directional Capability: The 11kW + 3kW model supports energy export and smart charging

These features make Ovar Tech solutions particularly competitive in cost-sensitive yet reliability-critical markets.

Comparison: Integrated vs Traditional Discrete Systems

Conclusion

Ovar Tech’s integrated charging solutions — particularly the 6.6kW OBC + 1.5/2kW DC-DC for standard commercial use and the bi-directional 11kW + 3kW for advanced marine and smart-grid applications — are ideal for any project where space, weight, reliability, and system simplicity matter. From urban delivery fleets and industrial equipment to luxury yachts and emergency vehicles, these modules deliver a balanced combination of performance, efficiency, and cost-effectiveness.

As the global shift toward electrification accelerates, integrated power electronics like Ovar Tech’s offerings will play an increasingly important role in enabling practical, reliable, and economically viable electric commercial and specialty vehicles.
