Detailed Testing Procedures
Follow these specialized procedures when testing electric truck charging installations. These detailed testing protocols ensure your charging infrastructure meets safety standards and performance requirements.
Electrical Safety Testing
- De-energize circuit and verify absence of voltage
- Perform insulation resistance test (megger test) on all conductors
- Verify resistance measurements exceed minimum requirements
- Conduct ground continuity testing using calibrated tester
- Perform polarity verification of all circuits
- Test GFCI protection by using test button and simulation method
Power Quality Assessment
- Install power quality analyzer at service entrance
- Monitor voltage levels during charging operations
- Record harmonics and power factor measurements
- Identify voltage sags or transients during peak loads
- Document baseline power quality metrics for future reference
- Verify readings comply with IEEE 519 standards
Full Vehicle Charging Test
- Connect electric truck with battery at 20-30% state of charge
- Initiate charging session using normal authentication method
- Monitor charge rate, power draw, and voltage stability
- Document charging time to 80% state of charge
- Test proper charge termination process
- Verify all charging data is properly recorded in management system
Load Management Testing
- Configure load management settings per site requirements
- Simulate multiple vehicle charging scenario
- Verify power allocation adjusts appropriately between chargers
- Test demand response functionality if implemented
- Confirm charging prioritization works as configured
- Document maximum site load during multi-vehicle charging
