Inspection

Charging infrastructure inspections are critical to ensuring electrical safety, regulatory compliance, and operational reliability of e-bus depots. These activities encompass periodic third-party audits, and seasonal preparedness checks of electrical, structural, and drainage systems to proactively identify risks, verify system integrity, and maintain safe charging operations under normal and extreme conditions. Effective implementation requires targeted mitigation actions by relevant stakeholder, as outlined in the following table for enforcement and compliance.
Q1. Before commissioning new EVSEs at a depot, which approval is mandatory?
Q2. An STU installs EVSEs rated above 200 kW. Which statutory requirement must be fulfilled?
Q3. Which inspection activity directly reduces flood-related electrical hazards during monsoon?
Q4. During cyclone alerts, which inspection-related preparedness measure is required?

S.No.

The following safety-critical systems and components shall be mandatorily checked during periodic inspections.

EVSE Commissioning Certification: DISCOM engineer to inspect and certify the EVSEs, before commissioning. Validity of said certificate be verified during periodical inspections. 

Statutory Electrical Approval: Get inspection and approval by the State Electrical Inspectorate for EVSE installation above 200kW. Validity of said certificate be verified during periodical inspections.

Periodic Safety Inspections: Organise periodical (say quarterly) inspections at charging station preferably by a third party and maintain the records for future reference. In that:

  • Examine the charging station equipment, operation, maintenance standards, and SOPs to ensure safe charging practices.
  • Inspect the entire electrical infrastructure supporting e-bus operations for compliance with electrical safety standards.

Drainage System Inspection: Carry out periodic inspection of sump pits, grates, and drainage systems to ensure unobstructed water flow.

Lightning Protection Validation: Ensure functionality of lightning protection systems prior to monsoon and cyclone seasons through visual inspection and electrical testing. This includes checking air terminals, down conductors, and earthing systems for integrity, as well as verifying grounding resistance (≤10 ohms) and electrical continuity. Surge protection devices shall also be inspected for proper operation. All identified issues must be rectified before the season. 

Pre-Monsoon Structural Checks: Conduct pre-monsoon body inspections and structural reinforcements for charging stations and electrical equipment.

Emergency Inspection SOPs: Develop SOPs for inspections, shutdown, deployment of sandbags during emergencies.
