The Schneider Electric HMIBSCEA53D1EDBSCP is an EcoStruxure EV Charging Expert charge controller that manages up to 5 charging stations and 20 zones with dynamic load management, allocating energy across vehicles based on priority profiles, time-of-use settings, and PV or BEMS integration via API. It runs on 12...24 V DC, draws 16 W, and communicates over Ethernet RJ45 (Cat.6) to the charging stations and via modem (3G/4G, ordered separately) to the central management system, using OCPP JSON. Rated IP40 for indoor installation, it mounts on a wall or rail in horizontal or vertical orientation — the 150 mm height, 157 mm width, and 46 mm depth fit a standard electrical enclosure.
The 20 zones and 4 zone levels let you segment a parking lot or depot into priority groups — for example, reserving a fast-charge zone for fleet vehicles while delaying public bays. Dynamic load management adjusts charging power in real time so the site's main breaker doesn't trip. With OCPP JSON and a web server for OCPP 1.6, the controller talks to any central management system that supports the standard — no proprietary lock-in. The modem slot (3G/4G, ordered separately) handles remote connectivity where Ethernet isn't run. Compliance with EN/IEC 61131-2 (programmable controllers), EN 55011 (industrial emissions), and EN/IEC 61000-6-4 (generic emission standard) means it's accepted in industrial environments without additional filtering for most sites.
