Efficient 6.6KW Liquid-Cooled On Board EV Charger<\/span><\/strong><\/p>\n

The 6.6KW Liquid-Cooled EV On Board Charger (Ovartech CAD662DF-400A) delivers high-efficiency, robust performance for electric vehicle battery charging, with global 85~265V AC input compatibility and IP67 protection for critical environments.<\/span><\/p>\n

The Ovartech CAD662DF-400A 6.6KW Liquid-Cooled EV On Board Charger is engineered to meet the core demands of efficiency, robustness, and safety for electric vehicle battery charging. Its wide AC input voltage range of 85~265V enables seamless global operation, making it an ideal choice for markets worldwide. With high-efficiency power conversion, this on-board charger (OBC) reduces energy consumption and lowers operational costs, delivering a more economical charging solution.<\/p>\n

The CAD662DF-400A features an intelligent charging mode that automatically adjusts voltage through CC\/CV (Constant Current\/Constant Voltage) phases and automatic cut-off, ensuring optimal battery performance and longevity. It also includes comprehensive safety protections: short-circuit, over-voltage, over-current, and over-temperature safeguards that activate during charging to protect both the charger and the vehicle battery.<\/p>\n

The integrated CAN-bus interface transmits real-time data\u2014including charging status, interlock connection, and fault or disconnection alerts\u2014to the VCU (Vehicle Control Unit) via the BMS (Battery Management System), enabling intelligent vehicle power management.<\/p>\n

Compliant with SAE J1772 and IEC 61851 international standards, the CAD662DF-400A series holds an IP67 rating, ensuring reliable performance in harsh and critical operating environments, from passenger EVs to commercial electric vehicles.<\/p>\n
