Integrated Chargers: Which Applications Are They Best Suited For?

Ovar Tech’s integrated charging solutions — such as the 6.6kW OBC + 1.5kW/2kW DC-DC and bi-directional 11kW OBC + 3kW DC-DC — are ideal for medium-duty commercial vehicles, fleet conversions, specialty EVs, and mid-range passenger EV platforms where space saving, high reliability, and cost-efficiency are critical. These compact 2-in-1 modules excel in applications requiring both efficient AC charging and stable low-voltage auxiliary power.

Key Advantages of Ovar Tech Integrated Solutions

Ovar Tech’s integrated chargers combine the On-Board Charger (OBC) and DC-DC Converter into a single compact, liquid-cooled unit. This design significantly reduces weight, wiring complexity, and potential failure points compared to separate components.

Popular Models Include:

• 6.6kW OBC + 1.5kW DC-DC
• Bi-directional 6.6kW OBC + 2kW DC-DC
• Bi-directional 11kW OBC + 3kW DC-DC

These units support wide voltage platforms (200V–800V) and deliver excellent thermal performance.

Best Application Scenarios

1. Medium-Duty Commercial & Delivery Vehicles
   Ideal for urban delivery vans, light trucks, and logistics fleets. The integrated design saves valuable chassis space while providing reliable 12V/24V power for auxiliary systems.
2. Fleet Electrification & Vehicle Conversions
   Perfect for companies converting existing diesel vehicles to electric. According to the 2025 McKinsey EV Fleet Report, integrated power modules can reduce conversion costs by 18–25% and installation time by nearly 40%.
3. Specialty & Purpose-Built EVs
   Well-suited for ambulances, refrigerated trucks, mobile service vehicles, and marine applications where reliability and compact size are essential.
4. Mid-Size Passenger EVs & PHEVs
   Excellent for SUVs, MPVs, and performance-oriented passenger vehicles that need fast AC charging combined with powerful auxiliary support.
5. V2G / V2L Ready Applications
   The bi-directional 11kW + 3kW version is particularly strong for Vehicle-to-Grid, Vehicle-to-Home, and Vehicle-to-Load scenarios.

Market Feedback & Adoption Trends

Many fleet operators and EV conversion companies report that Ovar Tech’s integrated chargers offer a good balance between performance, compactness, and cost. They particularly appreciate the reduced wiring complexity and improved thermal management compared to using separate OBC and DC-DC units. In commercial applications, these modules have demonstrated strong reliability under daily high-duty cycles.
