1 Product Overview
1.1 Product Introduction
The three phase 44KW charger is combination of two 22KW chargers in a floor-standing housing, which
provides AC charging to two electric vehicles simultaneously. It’s equipped with the function of charging by
scanning the RFID card. The RFID card is a key component to start or stop the charging session. The LED
indicators on the left and right panels help you understand what is happening with the charger by indicating
different colors.
With internet connection via a built-in EN-GATE, more functions like monitoring, operation management and
remote upgrade are available on the backend named Charge Management System.
Compatible with all types of cables, the socket locks the charging cable into the charger to ensure a safe
charging. The protection grade of the charger is high as IP54, with the excellent capacity of water and rust
proof, assuring the safe outdoor operation and maintenance. Designed according to Electric Vehicle Charging
System Standard EN 61851-1: 2011 and EN 61851-22: 2002, the charger is compliant with the industrial
standards and safe for usage.
