Frequently Asked Questions

What are the benefits of the 3-in-1 integration?
The 3-in-1 integration (OBC + DC/DC + PDU) optimizes space and weight, enhancing overall vehicle efficiency and simplifying the vehicle's internal architecture.
How does liquid cooling technology improve reliability?
Liquid cooling significantly reduces thermal resistance, allowing for superior heat dissipation compared to air cooling. This ensures consistent performance under high load and extends component lifespan.
What communication protocols are supported?
The system supports advanced CAN-FD communication for high-speed and reliable data exchange within the vehicle's network.
Is the system compatible with different battery voltages?
Yes, the output voltage is highly flexible with variants supporting 380V, 640V, and 750V systems, and can be adjusted according to specific battery voltage requirements.
What is the IP rating for environmental protection?
The integration unit is rated IP67, meaning it is completely protected against dust and can withstand temporary immersion in water.
Does this unit support bi-directional charging (Inverter mode)?
Yes, it features a 6KVA bi-directional inverter function, allowing the vehicle to provide 220Vac power to external loads (V2L).
