Understanding Smart Charging Graphs
The smart charging interface provides powerful visualization tools to help you monitor and understand charging activities. This guide will help you interpret the two main types of graphs available.
Group Allocation Graph Overview
The Group Allocation Graph shows how capacity is distributed across all EVSEs (charging stations) in your smart charging group. Here's what you'll see:
- A pink line showing the total available capacity for allocation
- Colored bars representing capacity allocated to each EVSE
How to Read the Group Graph
Each colored bar represents a different EVSE. The height of the bar shows how much charging capacity is allocated to that EVSE at any given time. Remember that this shows allocated capacity, not actual consumption.
EVSE Allocation Graph Details
To view detailed information for a specific charging station, click on its colored bar in the Group Allocation Graph. This will show you:
- Green bars showing allocated capacity for the specific EVSE
- Orange lines showing actual power consumption per phase
- Real-time charging data with precise measurements
Common Graph Scenarios
What if the graph shows "No Data Available"?
This can occur in two situations:
- There haven't been any charging sessions during the selected time period
- The charge station is offline and cannot send meter values
Why might allocated capacity be higher than actual consumption?
This is normal and can happen when:
- An EV is nearly full and naturally reduces its charging rate
- The EV's maximum charging capacity is lower than the allocated capacity
- The charging session is just starting or ending
Monitoring Best Practices
To get the most out of your smart charging monitoring:
- Regularly check the Group Allocation Graph for overall system performance
- Investigate individual EVSE graphs when you need detailed charging session data
- Use the date selector in the top left corner to review historical data
- Monitor for any offline EVSEs that might need attention
