Choosing an EV charger for your home or business seems simple — but the difference between a basic charger and a smart OCPP-enabled charger is enormous. Understanding what OCPP 1.6J brings to the table helps you make a decision that saves money, enables future growth, and integrates with platforms like Greems.
Basic Home EV Charger
A basic charger (sometimes called a "dumb" charger) plugs in and charges — that's it. There's no communication with any backend system, no remote control, no scheduling, and no billing capability. It simply delivers power whenever it's connected.
Basic chargers are cheaper upfront, and fine for simple single-user home use where you don't need visibility, load control, or billing. However, they cannot be integrated into a management platform, and they cannot participate in smart load balancing or time-of-use charging schedules.
Smart EV Charger with OCPP 1.6J
OCPP (Open Charge Point Protocol) 1.6J is the industry-standard communication protocol that allows a charger to talk to a Charge Point Management System (CPMS) like Greems. This two-way communication unlocks a completely different level of functionality:
Remote start/stop and scheduling: Charge sessions can be initiated, stopped, or scheduled remotely — perfect for time-of-use tariff optimization.
Real-time monitoring: Energy consumption, session status, and fault detection are all visible in real time through the Greems dashboard.
Load balancing: The charger can receive power allocation instructions from the management system, enabling multiple chargers to share available capacity intelligently.
Billing and access control: Sessions can be authenticated via RFID or app, and individual usage data is captured for accurate billing — essential for shared locations.
Which Should You Choose?
For a single home user with one car and no plans to expand: a basic charger may suffice. For anyone managing multiple chargers, shared locations, employee fleets, or commercial properties — an OCPP-compliant smart charger integrated with Greems is the only future-proof choice. The additional upfront cost pays back quickly through optimized charging costs and operational efficiency.
