Why is the Mainstream Trend Now OBC + DC-DC Integration (2-in-1 or 3-in-1)? How Much Weight and Cost Can It Save?<\/strong><\/span><\/h1>\n

The mainstream trend toward OBC + DC-DC integration (2-in-1 or 3-in-1 modules) is driven by the need for higher power density, reduced system complexity, lower weight, and better cost efficiency in modern electric vehicles. Integrated solutions can save 20\u201335% in weight and 15\u201328% in total system cost compared to discrete OBC and DC-DC units, while significantly improving reliability and simplifying vehicle integration.<\/span><\/p>\n\n\n\n

The Shift Toward Integration in EV Power Electronics<\/strong><\/span><\/h2>\n

In recent years, the electric vehicle industry has rapidly moved from using separate On-Board Charger (OBC) and DC-DC Converter units to highly integrated 2-in-1 (OBC + DC-DC) or 3-in-1 (OBC + DC-DC + PDU) modules. This architectural change is not just a trend \u2014 it has become the new standard for most new EV platforms, especially in the 6.6kW to 22kW power range.<\/span><\/p>\n

Ovar Tech, a specialized EV power electronics manufacturer established in 2010, has been at the forefront of this shift. The company offers a wide range of integrated solutions, including the popular 6.6kW OBC + 1.5kW DC-DC, 6.6kW OBC + 2kW DC-DC, and bi-directional 11kW OBC + 3kW DC-DC modules, supporting voltage platforms from 48V to 800V.<\/span><\/p>\n

Why Integration Has Become the Mainstream Choice<\/strong><\/span><\/h3>\n

1. Significant Weight Reduction<\/strong><\/span><\/p>\n

Integrated modules eliminate duplicate housings, separate mounting brackets, and heavy high-voltage wiring harnesses. Industry benchmarks show that a typical 6.6kW 2-in-1 module weighs 18\u201328% less than two discrete units. For a commercial van or mid-size SUV, this can translate into 4\u20138 kg of weight savings, directly improving driving range and vehicle dynamics.<\/span><\/p>\n

2. Substantial Cost Savings<\/strong><\/span><\/p>\n

While the integrated module itself may have a slightly higher unit price, the total system cost is usually lower. Savings come from:<\/span><\/p>\n
