What is the maximum number of concurrent WebSocket connections Tecell's OCPP gateway can sustain during peak charging hours?

OCPP Gateway WebSocket Connection Limits

Tecell’s OCPP gateway is designed to sustain a high number of concurrent WebSocket connections during peak charging hours, typically supporting hundreds of simultaneous connections per gateway instance. The exact limit depends on the hardware configuration and network capacity, but the system is built to handle the demands of large-scale deployments without performance degradation.

How Connection Limits Are Managed

The gateway uses a scalable architecture that dynamically allocates resources based on real-time demand. It monitors connection load and adjusts internal processing threads to maintain responsiveness. This ensures that even when many chargers connect simultaneously, the system remains stable and responsive.

Network bandwidth and CPU utilization are key factors in determining how many connections can be sustained. Tecell’s implementation includes buffering and queuing mechanisms to prevent bottlenecks during traffic spikes. These features allow operators to manage large fleets without compromising performance.

Practical Impact for Fleet Operators

Fleet operators benefit from this capability when managing multiple charging stations across different locations. The gateway’s ability to maintain consistent connections means fewer dropped sessions and more reliable communication with chargers. This is especially important for real-time monitoring and control during busy periods.

For example, a fleet operator with 200 chargers spread across a metropolitan area can rely on a single gateway instance to maintain stable communication. The system handles the complexity of managing these connections internally, so operators don’t need to worry about connection limits affecting service quality.
