Overview
The new high-efficiency three-phase PFC circuit topology is adopted, the power factor is greater than 0.99, and the harmonic distortion rate is ≤5%.
The high-frequency switching power supply module adopts full-bridge phase-shift soft-switching technology, and the execution efficiency is high.
The advanced digital current sharing technology effectively improves the current sharing accuracy and anti-interference; the first module sleep technology and the wheeling technology ensure the high-efficiency operation of the system;
Intelligent charging process control and perfect charging process monitoring and protection, fool-like operation;
One button is automatically filled with simple and practical;
Display the charging voltage, current, SOC and other information and operating status in real time, and display the charging degree after charging is completed;
Module hot swap technology makes maintenance more convenient;
Working environment temperature -20+50 °C.
Scope of application
Portable DC charging piles for private use (private cars, logistics vehicles, trucks, etc.)
The operating company leases with the car.
The yard is delivered with the car;
Particularly suitable for rapid deployment where the site is limited.
