About the programme
Course Overview
Electric vehicle charging infrastructure fails in ways that traditional plant maintenance teams have not previously had to diagnose, from worn connector pins and cooling fan degradation to communication faults between the charger and a remote back-office platform. This course prepares maintenance teams to keep charging infrastructure reliable, starting with the differences between AC, DC fast and ultra-rapid charger architectures and their component-level failure modes. Participants build preventive maintenance schedules covering connectors, cabling, cooling systems and electrical protection, then use remote monitoring platforms and diagnostic logs to triage faults before deciding whether a site visit is needed. The course covers electrical safety procedures specific to high-power charging equipment, managing uptime against charge point operator service commitments, and addressing weatherproofing and vandalism resistance at exposed sites. It closes with firmware update practices and cybersecurity considerations for networked charging equipment. Exercises include fault-code interpretation, a preventive schedule design task and an uptime-reporting workshop based on realistic charger performance data.

03Diagnosing Faults and Managing Uptime
2 sessions · 8 points
Session 1Using Remote Monitoring and Diagnostic Tools
- Interpret charger status data from OCPP-based remote monitoring platforms to triage faults remotely.
- Distinguish faults resolvable through remote reset from those requiring a site visit.
- Use diagnostic logs to identify recurring fault codes pointing to systemic component weaknesses.
- Prioritise dispatch of field technicians based on charger criticality and fault severity.
Session 2Managing Uptime Against Service Commitments
- Track uptime metrics and mean time to repair against charge point operator service level agreements.
- Set spare parts stocking levels for high-failure components to reduce repair turnaround time.
- Coordinate with network operators and payment providers when faults originate outside the charger itself.
- Report uptime performance trends to identify sites or charger models needing design or process changes.
04Managing Site, Environmental and Cybersecurity Factors
2 sessions · 8 points
Session 1Addressing Weatherproofing and Physical Resilience
- Inspect enclosure seals, drainage and ventilation to prevent moisture-related electrical faults.
- Assess vandalism and impact damage risks and specify protective bollards or enclosures where needed.
- Review cable management and connector storage design to reduce trip hazards and mechanical wear.
- Plan seasonal maintenance adjustments for extreme heat, cold or coastal corrosion environments.
Session 2Managing Firmware, Connectivity and Cybersecurity
- Schedule firmware updates for chargers and back-office systems without disrupting active charging sessions.
- Apply network security practices to protect charger connectivity from unauthorised access.
- Verify payment system compliance and data security requirements during maintenance visits.
- Maintain a configuration record of firmware versions and network settings across the charging fleet.
