DC-DC Converter: What Voltage Does It Convert High-Voltage Battery Power Into? Is 1kW\u20133kW Power Enough?<\/strong><\/span><\/h1>\n

DC-DC Converters in electric vehicles primarily convert high-voltage battery power (typically 360V\u2013800V) into low-voltage 12V or 24V to power the vehicle\u2019s auxiliary systems such as lights, infotainment, ECUs, pumps, and sensors. In most modern EVs, 1.5kW to 3kW is sufficient for the majority of passenger cars, while commercial vehicles may require higher power or multiple units.<\/span><\/p>\n\n\n\n

How DC-DC Converters Work in EVs<\/strong><\/span><\/h2>\n

The main traction battery in EVs operates at high voltage (360V\u2013800V) for efficient power delivery and fast charging. However, almost all vehicle accessories still run on traditional low voltage. The DC-DC Converter acts as the bridge, stepping down the voltage while maintaining stable output.<\/span><\/p>\n

Ovar Tech offers a full range of DC-DC Converters from 1kW to 3kW, supporting input voltages from 360V to 800V and output at both 12V and 24V systems. Their popular models include standalone 1.5kW and 2kW units, as well as integrated versions paired with 6.6kW or 11kW OBCs.<\/span><\/p>\n

Is 1kW\u20133kW Power Sufficient?<\/strong><\/span><\/h3>\n

Yes \u2014 for most passenger vehicles.<\/strong><\/span><\/p>\n

According to the 2025 Global EV Power Electronics Report by IHS Markit, the average continuous power demand for auxiliary systems in passenger EVs is between 850W and 1.8kW, with peak loads rarely exceeding 2.5kW.<\/span><\/p>\n

Unique Insight: Although peak power may reach 2.8kW momentarily (e.g., during simultaneous operation of steering assist, braking vacuum pump, and air conditioning), modern DC-DC converters use intelligent current limiting and supercapacitor buffering, making 2kW\u20133kW units highly capable with excellent headroom.<\/span><\/p>\n

For commercial vehicles, trucks, or vehicles with extensive auxiliary equipment (refrigeration, lifts, etc.), multiple DC-DC units or higher power (4kW+) may be needed.<\/span><\/p>\n
