EVSE Production End-of-Line and Aging Test Architecture
This production architecture separates fast, stable end-of-line decisions from deeper laboratory diagnosis and longer aging duties. Each station should be configured around the charger variants, cycle-time target, measurable limits, fixtures and data interface required by the manufacturer.
Reference application architecture
Who this workflow is for
- ✓ AC and DC charger manufacturers
- ✓ Production engineering teams
- ✓ Quality and manufacturing data teams
Engineering objectives
- ✓ Detect assembly, configuration and calibration issues with stable pass or fail limits
- ✓ Keep operator actions and variant selection controlled
- ✓ Link measurements and retest history to the charger identity
Reference system configuration
Final ratings, instruments, options and facility interfaces must be agreed against the actual test plan.
End-of-line test station
Runs product-specific identity, safety precondition, interface, communication and measured-output checks.
Connector fixtures and switching
Provides controlled, rated connections for each supported charger variant.
Power and aging equipment
Applies the specified duty profile using separately rated source, load, cooling and protection systems.
Test control and data interface
Selects the correct program and stores measurements, limits, results, versions and authorized retests.
Suggested execution workflow
- 1
Map production risks
Select checks that detect likely assembly, wiring, firmware, configuration or calibration defects.
- 2
Define station limits
Set initial conditions, stimulus, measurement, numeric acceptance limit and evidence for each product variant.
- 3
Validate fixtures and references
Use controlled reference units and fixture checks to establish repeatability across stations and shifts.
- 4
Sequence for cycle time
Run identity and fast preconditions before longer communication, power or aging operations.
- 5
Control failures and retests
Route diagnostic work away from the main line and require a recorded reason for repair, retest or override.
Expected project outputs
- ✓ Product-variant test matrix
- ✓ Station acceptance and reference checks
- ✓ Serial-number-linked measurements and results
- ✓ First-pass yield and failure data suitable for production review
Confirm before configuration
- ✓ Product variants and required takt time
- ✓ Power and aging duty profile
- ✓ Fixture, safety and facility interfaces
- ✓ MES or report format and retest permissions
Project evidence plan
Records that make the workflow reviewable
Agree these records before configuration so engineering, quality and acceptance teams can review the same scope and evidence.
Variant and limit matrix
Maps each charger configuration to the correct program, stimulus, measurement, numeric limit and fixture.
Fixture and reference checks
Demonstrates that station hardware and controlled reference units remain stable across shifts and maintenance.
Serial-number result record
Links measurements, limits, program version, instruments, timestamp and result to the manufactured charger.
Retest and override history
Provides an auditable reason for repair, repeat testing or authorized disposition without hiding first-pass failures.
