Product Overview
The SDEE_AC_FM is an AC series main control board developed in-house by our company. It is primarily designed for GB-standard single-gun AC charging piles, including wall-mounted and floor-standing models.
Built-in high-precision metering chip with external meter support; supports DL/T645-2007 protocol.
Supports four modular connectivity options: Ethernet, Bluetooth, Wi-Fi, and 4G.
Supports connection to major carrier platforms as well as the Shoudian maintenance platform.
Supports 3.5/4.3/7-inch displays; supports both landscape and portrait orientations; UI customization available.
Supports plug-and-charge, card swipe, QR code scan, appointment booking, and physical button activation.
Features emergency stop detection, grounding detection, over/under voltage, over/under current, CP pin-off, and CP grounding protection.
Supports gun temperature detection and vehicle-side diode detection.
Supports connection to TypeA+DC6mA-type leakage protection modules and DLB dynamic power limiting.
