EV charging station inspection frequency depends on usage type and governing requirements:
- Weekly checks: Basic visual inspections and cleaning of connectors/cables are recommended for all chargers.
- Annual professional inspections: Critical for commercial/public chargers to assess internal components, wiring, and safety compliance.
- Biennial expert inspections: Private/home chargers should undergo in-depth technical inspections every 24 months by licensed specialists.
For internal fault detection, focus on:
- Yearly electrical safety checks including cable integrity, connection tightness, and thermal performance.
- Biennial TR25:2022-compliant inspections (region-dependent) for corrosion, component wear, and lifecycle assessment.
- Immediate diagnostics if experiencing charging inconsistencies, overheating, or error messages.
Technical Reference 25 (common in Singapore) exemplifies rigorous standards requiring licensed professionals to inspect internal circuitry, ground fault protection, and insulation resistance.
