Maintenance Activities

A preventive and corrective maintenance regime aligned with OEM-prescribed schedules shall be implemented to identify defects early, maintain equipment integrity, and minimize operational and safety risks. Regular pre-operational checks, routine inspections, and prompt fault reporting form the backbone of effective maintenance management for charging stations. Successful implementation requires clearly defined mitigation actions by relevant stakeholders, as detailed in the following table to support enforcement and compliance.

QnA

Q1. During an internal audit, it is observed that preventive maintenance activities at a charging station are being conducted based on local experience rather than OEM documentation. What is the most appropriate corrective action?

Continue current practices if no failures are reported Align all preventive maintenance strictly with OEM-prescribed schedules Increase corrective maintenance frequency Outsource maintenance without revising schedules

Q2. Before commencing daily charging operations, which activity is mandatory to prevent operational failures and safety hazards?

Review of previous month's inspection reports Conduct daily pre-operational safety checks of charging equipment Load balancing through SCADA Third-party inspection of chargers

Q3. A charging station experiences repeated ground faults during monsoon season. Which maintenance activity directly addresses this risk?

Increasing inspection frequency of connectors Verifying waterproofing integrity during scheduled preventive maintenance Upgrading charger software Installing additional signage

Q4. During routine inspection, abnormal noise and overheating are detected in a charger. What is the correct immediate action?

Continue operation under observation Reset the charger and monitor performance Attach a fault tag and report for corrective action Wait for the next scheduled maintenance

S.No.

Fault Tagging Procedure

All preventive maintenance activities be meticulously conducted as per OEM prescribed schedules. Some of the maintenance activities are discussed here-under:

Preventive Maintenance Schedule: Carryout preventive maintenance activities periodically as per schedules and tasks prescribed by the OEM-Charging Systems.

Routine Equipment Inspections: Carry out daily, weekly and monthly inspection of charging station equipment with respect to tasks prescribed by the OEM-Charging Systems.

Waterproofing Integrity Verification: Verify waterproofing integrity of Charging sub-systems/ equipment, amongst other tasks, during scheduled preventive maintenance routines.

Pre-Operational Safety Checks: Conduct daily pre-operational checks to ensure serviceability before commencement of charging operations to avoid failures and potential safety hazards. After the day’s operations, report any damage or malfunctioning for corrective action.

Fault Tagging Procedure: In the event of any abnormality, attach a fault tag to it immediately and report the matter to Depot Workshop System/ Charging In-charge for corrective action.
