Connected Mobility

Buses enabled with ITS

Real-time GPS tracking, onboard CCTV surveillance, passenger information displays and fleet telematics — making our buses ideal for multi-modal transport and smart-city deployments.

  • Real-time tracking
  • Video surveillance
  • Passenger info system
  • Telematics gateway
Depot-Friendly Charging

Fast charging technology

High-power AC charging brings the battery from 0 to 100% State of Charge in 2–3 hours. No dependence on commercial fast-charging stations means significant savings on infrastructure and maintenance.

  • 0–100% SOC in 2–3 hrs
  • GB/T standard interface
  • Ground-mounted charger
  • IP55 enclosure
State-of-the-Art Battery

Battery Technology Built for a Better Tomorrow

Lithium Iron Phosphate (LFP) chemistry brings industry-leading thermal stability, long cycle life and high energy density to every TRBL electric bus. LFP cells are far less prone to thermal runaway than conventional Li-ion — ensuring safer operation across India's climate extremes.

Five-in-One Integrated Controller
  • UBS-II standard compliant
  • Temperature sensors across the pack
  • Intelligent Battery Management System (BMS)
  • Active liquid cooling system
  • Fire-proof battery pack & electric powertrain
  • Automatic fire extinguisher in battery pack
  • Electricity leakage sensors
  • Long life with minimal maintenance
  • Low energy consumption per km
