Tecell’s Charge Management System (CMS) supports integration with legacy AC chargers using the OCPP 1.6J protocol. This compatibility allows operators to manage older charging equipment through a unified platform, enabling features like remote monitoring, firmware updates, and charging session control.
How OCPP 1.6J enables legacy charger support
OCPP 1.6J is designed to bridge communication gaps between modern charge management systems and older AC chargers that may not natively support newer protocols. Tecell’s CMS leverages this version to translate commands and data between the two systems. The protocol ensures that legacy hardware can be upgraded in functionality without requiring full replacement.
This compatibility is especially useful for fleet operators or property managers who have invested in AC charging infrastructure but want to centralize control. It allows them to maintain existing equipment while gaining access to advanced features like dynamic pricing or load balancing.
Operators using older chargers can also benefit from real-time diagnostics and alerts through the CMS, improving operational visibility and reducing downtime.
Practical implications for charge point operators
For charge point operators managing mixed fleets of new and legacy chargers, Tecell’s CMS provides a single pane of glass for all devices. This simplifies operations by eliminating the need for multiple management tools or manual oversight of older hardware.
Legacy AC chargers integrated via OCPP 1.6J can participate in smart charging programs, such as time-of-use pricing or grid-supportive charging. This helps operators align with evolving energy policies and reduce operational costs.
Additionally, the CMS supports firmware updates for compatible legacy chargers, extending their useful life and ensuring compliance with updated safety or performance standards.
