The Charger Uptime page provides data on the uptime and utilization of your chargers, both on a per connector and a per depot basis.
Using the Charger Uptime page, you can view a summary of your charger uptime, look at the uptime trend over time, and view a detailed plot of every connector’s uptime to analyze charger activity patterns.
The Charger Uptime page provides a comprehensive set of filters you can use to view data by a single depot, group of chargers, manufacturers, or models over a specific time range.
The Charger Uptime page uses industry-standard definitions of uptime as included in the National Electric Vehicle Infrastructure (NEVI) program and the California Energy Commission’s California Electric Vehicle Charging Infrastructure Reliability docket.
Uptime is generally tracked as a percentage of total time during which a charger is:
Networked
Operational (OCPP status is not Faulted or Unavailable)
Not within an excluded downtime/planned maintenance window
Camber determines whether a charger is networked based on the status of a OCPP web socket. Uptime metrics are calculated once a day based on data with one-second resolution.
The Charger Uptime Summary tab displays:
Uptime: Uptime % for all connectors matching the search criteria within the selected time range
Operability: Donut graph of total % of time connectors were either Operational, had Downtime, or were in Maintenance
Status: Pie chart indicating the % of time connectors spent in each status
Using the the Uptime, Operability, and Status widgets you can determine your charger uptime for the period and the breakdown of downtime to learn more about the cause of reliability issues.
The Summary tab also includes a bar graph of the uptime of every connector included in the filter. You can choose to view the data by individual connector or all connectors at a Customer or Depot (if no Depot is defined, then the data is displayed grouped by Customer)
The Charger Uptime Trend view displays connector uptime for all connectors matching the filter criteria, within the selected time range, plotted as a timeseries. The granularity of each point in the timeseries depends on the date range selected.
For a date range over one month, each point on the x-axis is one month
For a date range between one month and one day, each point on the x-axis is one day
For a single day time period, uptime is plotted in 15 minute increments.
Each data element plotted on the graph is interactive. You can click each bar to drill in to the lower granularity (from one month to all of the days in the month/from one day to all of the 15-minute periods in one day). You can zoom back out to a wider view by clicking the date breadcrumb on the top left of the graph canvas or the Reset Time Range control.
You can choose to view trend data by uptime metrics or by status.
The Charger Uptime Detail view tab displays each connector included in your search criteria and the raw status changes that occurred over your selected time period. There can be a large number of status changes within a short period of time -as a result, the Detail view is limited to plotting 3 days in a single view.
You can use the Detail view to investigate how status changes occurred across a depot in a single view and the pattern of charging across all of the vehicles visiting a single depot.
