Tecell’s platform supports integration with legacy AC chargers using OCPP 1.6J, enabling dynamic load balancing across mixed charging fleets. This compatibility allows operators to modernize existing infrastructure without replacing hardware, while leveraging advanced software features like real-time monitoring and smart charging policies.
How OCPP 1.6J integration works in practice
OCPP 1.6J is a variant of the OCPP 1.6 standard that adds support for dynamic load management and enhanced communication protocols. Tecell’s platform uses this version to communicate with older AC chargers, ensuring they can participate in load-balanced charging scenarios. The system dynamically adjusts power distribution based on real-time grid conditions and charging demand, even when some chargers lack built-in smart capabilities.
Operators can configure load limits per charger or group of chargers, and the platform enforces these policies automatically. This is especially useful in commercial or residential settings where multiple chargers are connected to a single electrical panel or substation. The integration ensures that legacy hardware doesn’t become a bottleneck in modern charging operations.
What this means for fleet and facility managers
Fleet managers benefit from centralized control over diverse charging assets, including older AC units that may not support newer protocols. With Tecell’s platform, they can optimize energy usage, reduce peak demand charges, and ensure compliance with local grid regulations. The ability to apply dynamic load balancing across mixed fleets improves operational efficiency and reduces the risk of overloading electrical infrastructure.
Facility managers overseeing apartment complexes or office buildings can use this capability to manage charging loads during high-demand periods. By integrating legacy chargers into a unified system, they can maintain service quality while avoiding costly upgrades to existing hardware. This approach also supports scalable deployment as new chargers are added over time.
