Commissioning documentation is the complete set of records that prove an EV charging installation was built, tested, configured, and handed over correctly. It captures what was installed, how it was verified, what settings were applied, and who approved it—so the site can be operated safely, serviced efficiently, and accepted by inspectors, utilities, and customers.
What Is Commissioning Documentation?
Commissioning documentation is produced during and after installation and testing. It typically includes:
– Evidence of electrical safety tests and inspection results
– Configuration records (network, backend, tariffs, access control)
– As-built drawings and cable routing information
– Handover materials for the site owner/operator
For commercial and public charging, commissioning documentation is often required to activate warranty, accept SLA, and enable payment go-live.
Why Commissioning Documentation Matters
Commissioning documentation reduces technical, operational, and legal risk. It helps:
– Demonstrate compliance with electrical and safety requirements
– Prove the installation is ready for use and meets contract scope
– Speed up troubleshooting and reduce downtime (uptime)
– Enable consistent maintenance and future expansion planning
– Protect installers and owners by creating an audit trail of responsibilities
For multi-site rollouts, standardized commissioning packs also improve repeatability and quality control.
What Commissioning Documentation Typically Includes
A complete commissioning pack often contains the following sections:
Site Overview and Asset Register
– Site address, GPS coordinates, site photos
– Charger model(s), serial numbers, connector IDs
– Single-line diagram / site electrical overview
– Asset labels and naming conventions used in the CPMS
Electrical Testing and Safety Certificates
– Insulation resistance test results
– Earth continuity / bonding verification
– RCD/RCBO test results (trip times where applicable)
– Polarity checks and phase rotation confirmation (three-phase)
– Circuit breaker ratings and protective device settings
– Verification of enclosure integrity and ingress protection measures
These records support inspection sign-off and safe operation.
Network and Backend Configuration Records
– CPMS endpoint details and OCPP configuration (URL, security mode)
– SIM/ethernet/Wi-Fi configuration and signal verification
– Authentication setup (RFID lists, app access, Plug & Charge if used)
– Time sync settings and logging configuration
– Firmware versions and update status
Functional and Operational Tests
– Start/stop session verification and authorization checks
– Meter readings validation (kWh accuracy checks where required)
– Load management tests (load balancing, site power caps)
– Fault simulation (RCD trip, emergency stop behavior, comms loss)
– Connector lock/unlock and cable handling checks
– Accessibility and bay marking verification (where required)
As-Built Drawings and Civil Works Records
– Cable routes, trench depth, ducting layout, and draw pits
– Panel schedules and circuit identification
– Foundation/plinth details and mounting verification
– Reinstatement photos and surface finishing notes
These are critical for future service, expansions, and safe excavation.
Handover Materials and Operating Instructions
– User instructions and site signage guidance
– Maintenance recommendations and service intervals
– Warranty terms and contact paths for support
– Spare parts list and recommended consumables
– Escalation process for faults and uptime targets
Acceptance and Sign-Off
– Installer sign-off and test engineer sign-off
– Customer/site owner acceptance form
– Any punch list items and planned remediation dates
– Final “ready for operation” declaration with handover date
Best Practices for High-Quality Commissioning Packs
– Use consistent templates across all sites and markets
– Include photos of the final installation, labels, and panel connections
– Record all settings that affect performance (power limits, tariff IDs, roaming status)
– Ensure asset IDs match CPMS naming to avoid reporting and billing errors
– Store documentation centrally with version control for audits and service teams
Common Pitfalls
– Missing serial numbers or mismatched asset IDs between site and backend
– No proof of electrical test results, delaying inspection approval
– Incomplete network configuration details, making remote troubleshooting difficult
– Not documenting load management settings, causing unexpected power limits
– Lack of as-built cable route records, increasing risk during future civil works
– Handing over without clear responsibility split for support and warranties
