Monitoring

Continuous real-time monitoring of weather, energy systems, electrical safety, fire risks, and critical infrastructure is essential to ensure safe, efficient, and resilient e-bus depot operations. Effective implementation requires targeted mitigation actions by relevant stakeholder, as outlined in the following table for enforcement and compliance.

Hydrogen Flame Detection

The following safety-critical systems and components shall be mandatorily monitored through various devices as mentioned below:

Real-Time Weather Integration: Share and integrate IMD’s API with operating agencies for real time tracking of weather. Real-time charging dashboards fed via an IMD API, and site sensors should display ambient temperature, heat index, and short‑term forecasts so depots can dynamically schedule charging windows.

Smart Energy Monitoring: Integrate and monitor load management software, energy dashboards, and smart metering tools to optimise charging schedules, avoid peak demand penalties, and monitor power quality in real time.

Thermal Imaging Surveillance: Install and monitor thermal imaging cameras on or near electrical panels for live monitoring of temperature and to identify overheating early.

Electrical Leakage Monitoring: Install and monitor Earth leakage relays (ELRs) and insulation monitoring devices (IMDs) on feeder circuits.

No-Contact Electrical safety tools: To minimise the risk of electrical injuries particularly from arc flash and arc blast hazards, maintenance personnel should avoid physical contact with energised components and remain outside the arc flash boundary wherever possible.

Use non-contact voltage detectors or electrical testers to confirm the presence or absence of voltage before any work.
Employ non-contact infrared thermometers for rapid temperature checks of chargers, cables, and panels to identify overheating.
Use Remote display or wireless multimeters that allow electrical measurements to be viewed from a safe distance.

Monitor and integrate SCADA/BMS with dashboards for real-time display of:

Voltage and current levels
Earth faults, insulation degradation
Equipment status and error logs

Fire Detection Monitoring: Monitor the detection of potential fire in the depot/ terminal through BMS and monitor the charging infrastructure.

Hydrogen Cooling Systems: Install and monitor cooling systems for H₂ cylinders at easily accessible locations.

Smoke Heat Detection: Install and monitor smoke and heat detector systems.

Hydrogen Flame Detection: Install detection of ‘invisible’ H₂
