EV CHARGER - 350W

Description

The Off-Board EV Charger with Digital Half Bridge LLC topology uses mathematical modelling to achieve high energy density, increasing safety, reducing weight, and improving efficiency, with AIS156 standards. It supports different battery types, and charging methods include Pre-charge, CC, CV, CP, floating/trickle, or Power exchange on CAN Command this platform can support up from 0.2KW~1.5KW.


Features

  • Charge Voltage Cut-off To Prevent The REESS From Being Overcharged 
  • Whenever REESS is Connected For Charging Soft-start Function Is Activated 
  • Deep Discharge Condition Of REESS is Detected By Pre-charge Function 
  • Protects Against Input Supply Variation 120v ~ 280v 
  • Earth Leakage Detection: Input RCD 30mA at Plug Input To Meet AIS156 
  • On-board/portable Charger Have CAN, UART To Communicate With BMS
