Technical Expertise & Performance
1. Superior Liquid-Cooled Stability
In high-power electronics, managing thermal loads is critical for component life. Our 13kW OBC features an integrated liquid-cooling channel designed for flow rates of ≥ 10L/min. By utilizing the vehicle’s primary coolant loop, the unit prevents thermal derating even in high-ambient environments (Operating up to 85°C inlet coolant temp), ensuring a consistent power curve during rapid charging.
2. Versatile Bidirectional Inverter (V2X)
Empower your customers with mobile energy. The integrated inverter converts high-voltage DC into a stable 220VAC (± 5%) single-phase output.
-
Clean Energy: Low harmonic distortion (THDv < 3%) makes it safe for sensitive electronics like laptops, medical equipment, or household appliances.
-
Industrial Response: A dynamic response time of 60ms ensures seamless transitions during varying load demands.
3. Precision Power Control
Reliability in power electronics requires strict accuracy. This unit delivers ±1% voltage accuracy and ± 3% current accuracy, preserving the chemical life of the battery pack through precise charging control.

Frequently Asked Questions (FAQ)
Q: Why choose liquid cooling for a 13kW unit?
A: At 13kW, heat generation is substantial. Liquid cooling provides significantly higher heat dissipation efficiency than air cooling, allowing for a more compact unibody design and preventing power throttling in hot climates.
Q: Is this charger compatible with 800V battery architectures?
A: Yes. We offer a specific configuration with an output range of 500V–850VDC, making it fully compatible with the latest generation of ultra-fast charging high-voltage platforms.
Q: How does the “Wake-up” feature work for the BMS/VCU?
A: The unit provides a low-voltage 12VDC & 200mA Max WAKE_UP signal, which follows the VCC voltage to activate the Battery Management System or Vehicle Control Unit when charging begins.
Q: Does it support scheduled or timed charging?
A: Yes. Through the CAN-BUS interface and multiple wake-up methods (AC, CC/CP, or Hardwire EN), the unit supports advanced vehicle-level scheduling and smart charging protocols.
