Issue:

In bus interchanges and depots, multiple electric buses are charged simultaneously across several charging stations. However, without a clear visual indication system, it is difficult for operators and technicians to quickly identify each charger’s status.

They may not know:

• Which charger is available for the next bus
  
• Which bus is currently charging
  
• Which charging session is completed
  
• Which charger has encountered a fault or error
  

This lack of visibility can result in:

• Delayed response to faults or system issues
  
• Inefficient use of charging infrastructure
  
• Increased waiting time for buses
  
• Operational confusion during peak hours

Solution

By installing a multi-colour LED beacon on each EV charger, the charging status becomes immediately visible across the entire depot.

Each colour represents a specific status:

• Green: Charger available (no bus connected)
  
• Amber: Authentication / handshake in progress
  
• Blue: Bus is connected and charging
  
• Red (Flashing): Fault or error detected
  
• White: Charging completed
  

This simple but effective visual system allows operators to:

• Monitor multiple chargers at a glance
  
• Identify issues instantly without checking systems
  
• Respond quickly to faults or abnormal conditions
  
• Improve overall charging efficiency and workflow

Summary

A multi-colour LED beacon system provides clear, real-time visual indication of EV bus charging status at bus interchanges and depots.

By using colour signals to represent different charging conditions, operators can easily monitor charger availability, charging activity, and faults—without relying on complex systems or manual checks.

This improves:

• Operational efficiency
  
• Response time to issues
  
• Charger utilization
  
• Safety and workflow clarity

Ultimately, it enables smoother and more reliable electric bus fleet operations.
