CTS Premium 11kW 22kW 3-Phase Liquid Cooled On Board OBC Charger with CAN Bus 2.0B for Electric Vehicle EV Factory Price
As the energy capacity of electric vehicles grows, the demand for charging speed and system reliability has never been higher. The CTS Premium Series 11kW/22kW 3-Phase On-Board Charger (OBC) features advanced liquid cooling, allowing it to maintain optimal operating temperatures under continuous high-power output. As a standard 380V 3-phase AC charging core, it significantly shortens charging time and integrates deeply with your vehicle's BMS via smart CAN Bus 2.0B, providing a safe, stable, and high-efficiency energy conversion heart for your EV project.
Key Advantages & Features
3-Phase High-Power Performance: Supports both 11kW (16A) and 22kW (32A) 3-phase AC input. Charging speeds are up to 3x faster than standard single-phase 7kW chargers, effectively eliminating range anxiety.
Advanced Liquid Thermal Management: Purpose-built for high power density. Liquid cooling provides superior heat dissipation compared to air-cooled models, ensuring full power output without thermal derating, even in extreme summer heat.
Automotive-Grade CAN Bus 2.0B: Full support for CAN bus communication protocols, enabling sub-second response times and precise power regulation between the VCU, BMS, and Charger.
Wide Output Voltage Versatility: A flexible output range (200V-750V) covers a wide variety of EV platforms, from 400V standard systems to advanced high-voltage powertrain architectures.
Rugged IP67 Sealed Design: Housed in a premium die-cast aluminum enclosure with exceptional water, dust, and vibration resistance—built for harsh engine bays and outdoor all-weather environments.
