The category of controllers and RFID cards for car chargers includes hardware and software components required for the operation and access management of charging stations. The controllers (load management units, OCPP/Modbus gateways, DIN-rail mounted controllers) provide intelligent management of the chargers: charging scheduling, load balancing, integration of consumption measurement (current transformer/smart meter), remote monitoring and firmware updates. These units communicate via Ethernet, Wi-Fi, RS-485/CAN or 4G and can be easily integrated into existing energy management systems.

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