Optimizing AGV charging schedules is critical for reducing electricity costs, maintaining battery health, and ensuring uninterrupted warehouse operations. Modern RCS platforms provide multiple tools to control charging dynamically.

1. Time-Based Charging for Off-Peak Rates

• Night-time full charges: Schedule AGVs to charge only during off-peak hours (e.g., 10 PM – 6 AM).

• Configurable charge limit: Avoid topping up beyond required SOC for upcoming tasks.

• Staggered start times: Each AGV starts charging at a different time to smooth power draw.

Implementation Tip: Use your RCS scheduler and align each AGV’s window with your utility’s Time-of-Use rate plan.

2. Opportunity Charging During Idle Periods

Opportunity charging allows AGVs to recharge briefly during operational gaps such as lunch breaks or pallet staging times.

• Top off batteries when the AGV is idle.

• RCS ensures safe charge rates—prevents rapid overcharging.

• Ideal for high-throughput warehouses where AGVs finish tasks at different times.

Tip: Configure thresholds, e.g., “charge if SOC < 60% and dock is free.”

3. Preventing Circuit Overload

Large fleets charging simultaneously can trip breakers. Modern RCS systems provide several mitigations:

• Load balancing: Only allow a defined number of AGVs to charge at once; remaining AGVs queue.

• Peak-shaving: RCS integrates with building energy monitors to throttle or delay charging dynamically.

• Staggered docking: Assign AGVs to chargers based on task completion schedules.

4. Integration with Smart Grid or Energy Monitors

• Advanced RCS can read real-time energy usage from your building’s energy management system (BEMS).

• Automatic adjustments to charging schedule reduce costs and smooth load.

• Supports participation in demand-response programs.

• Some RCS platforms provide APIs for monitoring and automation integration.

Check: Confirm that your RCS can read data from your specific smart meter or energy monitoring system.

5. Recommended Workflow for Fleet Charging

1. Define off-peak hours and SOC targets for each AGV.

2. Configure RCS scheduler for night-time and opportunity charging windows.

3. Enable load balancing to avoid simultaneous peak draw.

4. Optional: Integrate energy monitor for real-time optimization.

5. Test for 1 week to ensure chargers, breakers, and battery health are within limits.

✅ Key Takeaways

• Scheduled night charging lowers electricity cost and prolongs battery life.

• Opportunity charging maximizes fleet uptime without overloading circuits.

• Load-balancing prevents breaker trips in large fleets.

• Smart grid integration allows real-time energy optimization in high-density operations.
