Product Overview
SDEE-DC-OB2 is the main control board for our company's self-developed DC charging series, primarily designed for dual-gun DC charging stations including Euro-standard, US-standard, one-country-one-Euro, one-country-one-US, one-Euro-one-US, and GB-standard configurations. It is compatible with wall-mounted, floor-standing all-in-one units, or charging stacks.
The hardware supports integrated Ethernet, 4G, Bluetooth, and Wi-Fi modules, with seamless on-screen switching between connectivity options.
Built-in OCPP1.6J communication protocol, expandable to OCPP2.0, supports Tuya, and enables remote maintenance platform connectivity for international deployments.
Supports multiple screen sizes (typical: 4.3/7/100/13 inches), multi-language display, and UI customization.
Supports multiple charging methods: EVCCID (MAC), card swipe (POS compatible), password entry, and QR code scanning.
Supports EMS integration, power limiting, on-demand diagnostic log retrieval, and OTA upgrades (via operations platform, maintenance platform, or charger display).
Connected to major international platforms (PEA, PLN, LMS, MONTA). Our charging stations have obtained OCA certification and TUV certification in collaboration with customers.
