EV Charging Network Connectivity & Uptime Audit Checklist [FREE PDF]

EV charging network connectivity and uptime audits are essential for ensuring that charging stations remain operational, accessible, and compliant with NEC Article 625 and SAE J1772 communication protocols. Network downtime not only impacts revenue but may constitute a violation of operator agreements and local utility interconnection standards. Regular audits help identify firmware gaps, communication failures, and hardware faults before they escalate into extended outages.

• Industry: EV Charging
• Frequency: Weekly
• Estimated Time: 45-60 minutes
• Role: Network Operations Manager
• Total Items: 35
• Compliance: NEC Article 625 - Electric Vehicle Charging System Equipment, NFPA 70 National Electrical Code Section 625.2, SAE J1772 EV and PHEV Conductive Charge Coupler Standard, UL 2594 Standard for Electric Vehicle Supply Equipment, OSHA 29 CFR 1910.303 General Electrical Safety Requirements

Network Connectivity Status

Verify that each charging station maintains a stable and authenticated connection to the network management system.

• Is the station currently showing an online status in the network management dashboard?
• Has the station maintained at least 98% uptime during the audit period?
• Is the network communication protocol (OCPP version) current and supported?
• Are all active network alarms or fault codes logged and acknowledged?
• What is the current average network latency for this station (ms)?

Firmware & Software Compliance

Confirm that station firmware is current, authenticated, and free from known vulnerabilities.

• Is the station running the latest manufacturer-approved firmware version?
• Was the most recent firmware update successfully applied without rollback?
• Is the station's TLS/SSL certificate valid and not within 30 days of expiration?
• Have remote firmware update capabilities been tested successfully in the past 90 days?
• Are firmware update logs retained for a minimum of 12 months?

Session & Transaction Audit

Review charging session records for completeness, accuracy, and anomaly detection.

• Do session start and stop records align between station logs and network backend?
• Are there any sessions with abnormal duration (over 24 hours) flagged in the audit period?
• Is energy delivered (kWh) per session within expected range for the connector type?
• Have any unauthorized or failed authorization attempts been recorded?
• What is the total number of completed charging sessions during the audit period?

Hardware & Connector Inspection

Physically inspect EVSE hardware, connectors, and mounting for damage, wear, and code compliance.

• Are all charging connectors (J1772, CCS, CHAdeMO) free from visible damage or corrosion?
• Is the cable management system (holster, retractor) fully functional and undamaged?
• Is the EVSE enclosure sealed, with no unauthorized openings or damaged panels?
• Are status indicator lights (LED/LCD) operational and displaying correct state?
• Please attach a photo of the connector and front panel of each audited station.

Power & Electrical Integrity

Verify electrical supply quality, grounding, and protection device status at each station.

• Is input voltage within the rated operating range for this EVSE (±10% of nominal)?
• Are ground fault protection (GFCI) devices tested and functional?
• Is the dedicated circuit breaker for this station properly labeled and in the ON position?
• Is the equipment grounding conductor (EGC) connection verified and free from corrosion?
• What is the measured input voltage at time of inspection?

Remote Monitoring & Alerting

Confirm that remote monitoring, alert escalation, and reporting functions are active and correctly configured.

• Are automated fault alerts configured and routing to the correct operations team?
• Have all critical alerts from the audit period been responded to within the SLA timeframe?
• Is the station included in the automated daily uptime report?
• Are energy consumption reports being generated and archived per utility agreement requirements?
• Is load management or smart charging functionality (OCPP Smart Charging) active and verified?

Corrective Actions & Documentation

Document all findings, corrective actions taken, and follow-up items from this audit.

• Were any stations placed out of service during this audit?
• Have all out-of-service stations been tagged with proper lockout/tagout signage?
• Are work orders created for all identified deficiencies requiring physical repair?
• Please describe any major findings or corrective actions taken during this audit.
• Has this audit report been submitted to the site manager and network operations lead?
