The "Controllers and RFID Cards for EV Chargers" category encompasses the hardware and software components necessary for operating and managing access to charging stations. Controllers (load-management units, OCPP/Modbus gateways, DIN rail-mounted controllers) provide intelligent supervision of chargers: charge scheduling, load balancing, integration of consumption metering (current transformer/smart meter), remote monitoring, and firmware updates. These units communicate via Ethernet, Wi-Fi, RS-485/CAN, or 4G connections and can be easily integrated into existing energy management systems.

RFID cards and key fobs provide identification and authorization management: access linked to user accounts, time- and quota-based permissions, guest cards, and simple administration via the charger management interface. Typical RFID technologies (e.g., MIFARE DESFire / MIFARE Classic) are supported, and cards can be easily programmed and disabled. Combined solutions (controller + RFID + smart metering) are ideal for residential, corporate, or public charging parks where security, user management, and cost-effective energy consumption are important.
