TECHNICAL RESOURCE
Five operating metrics every charging network should review
Measure service from the driver and operator perspectives, then turn exceptions into maintenance actions.
Measure service from the driver and operator perspectives, then turn exceptions into maintenance actions.
Availability and success
Distinguish device online time from user-visible availability and successful charging starts. A connected charger can still be unusable because of authorization, cable or vehicle issues.
Utilization and energy
Track sessions, occupied time and energy per outlet and site. Compare like-for-like sites by operating hours, dwell time and power class.
Fault recovery
Measure detection-to-acknowledgement, diagnosis and restoration separately. Record root cause and recurring incidents to improve preventive work.
Project application
If a charger is online 99% of the time but one in ten attempts fails to start, users experience a worse service than the uptime figure suggests. Define a session attempt, a successful start and an available outlet consistently across all sites before comparing performance. Review five metric families together: user-visible availability, start success, delivered energy, utilization and time to restore service. Segment by site, model, connector and time of day. Relate alert logs to support tickets so repeated faults do not disappear inside an average.
What this decision should produce.
- Publish a monthly operating review with baseline, exceptions, owner and action date. A dashboard becomes useful only when the team can close issues and verify whether the next month improved.

Practical answers about Five operating metrics every charging network should review. No guesswork.
Ask about your project3 questions
01Is uptime the same as charging success?
No. A charger may be online while the driver cannot complete a session.
02Why separate availability and start success?
An outlet may report online while drivers cannot authorize or complete charging.
03What should a monthly review produce?
Named corrective actions, owners, due dates and evidence that the next period improved.
