Mobile EV Charger Commissioning and Maintenance Workflow
This mobile workflow supports commissioning, maintenance and fault isolation when a charger cannot be moved to a fixed laboratory. The project configuration must match the installed connector and ratings, define how charging energy will be handled and keep the field record within the checks actually executed.
Reference application architecture

Who this workflow is for
- ✓ Charging station operators
- ✓ Commissioning and maintenance contractors
- ✓ Manufacturer field service teams
Engineering objectives
- ✓ Reproduce a vehicle-side charging sequence without using a customer EV as the primary test instrument
- ✓ Compare site behavior with a known commissioning baseline
- ✓ Preserve evidence needed for repair confirmation or laboratory escalation
Reference system configuration
Final ratings, instruments, options and facility interfaces must be agreed against the actual test plan.
Mobile test platform
Carries the selected tester, accessories and supporting instruments to the charging site.
Connector-specific tester
Simulates the required GB/T, CCS2, CHAdeMO, Type 1 or Type 2 vehicle-side workflow.
Approved energy path
Uses a compatible external load or other approved arrangement where sustained power transfer is required.
Field evidence package
Records charger identity, tester configuration, measurements, messages and the result of each planned check.
Suggested execution workflow
- 1
Prepare from site information
Confirm charger model, connector, rating, supply, access, visit purpose and available load before dispatch.
- 2
Complete safety preconditions
Follow the site procedure for visual, grounding, supply and connector checks before functional testing.
- 3
Run the normal sequence
Observe connection, readiness, charging, measured output and controlled stop using a repeatable baseline.
- 4
Investigate the reported condition
Change only the condition required to reproduce the issue and retain surrounding protocol and measurement evidence.
- 5
Confirm handover or escalation
Repeat affected checks after repair, or preserve the configuration and first divergent state for laboratory reproduction.
Expected project outputs
- ✓ Site-specific test scope and equipment list
- ✓ Baseline or post-repair functional record
- ✓ Measurements and communication evidence tied to the charger
- ✓ Open findings with a defined owner and follow-up action
Confirm before configuration
- ✓ Installed connector and charger rating
- ✓ Permitted field tests and site safety controls
- ✓ External load or energy-absorption arrangement
- ✓ Required acceptance report and escalation process
