EV Bus : total cost of ownership

India and Electric Bus

  • India’s first electric bus was launched in Bengaluru in 2014.
  • The first inter-city bus service, from Mumbai to Pune, was launched in 2019.
  • In October 2016, Ashok Leyland, launched the first 100% India-made electric bus. The series have been named Circuit and it can carry 35 to 65 persons at a time.
  • Pune Mahanagar Parivahan Mahamandal (PMPML) have employed electric buses supplied by BYD and its Indian partner Olectra Greentech.
  • Himachal Road Transport Corporation have started to employ Goldstone-BYD (Model K7e Buzz – 9 meters) in local routes in Himachal Pradesh
  • BEST (Brihanmumbai Electric Supply and Transport) have started to employ Goldstone-BYD buses on few selected routes in Mumbai
  • Telangana State Road Transport Corporation (TSRTC) have started to ply Goldstone-BYD buses in Hyderabad and Secunderabad
  • Navi Mumbai Municipal Transport (NMMT) have started to ply JBM suppplied JBM Solaris buses on local routes.
  • Ahmedabad Janmarg Ltd. have employed buses manufactured by Ashok Leyland in BRTS

EV BUS

The electric buses are of two configurations based on bus length: 9 m and 12 m. Considered the same for Total Cost of Ownership calculations on the basis of data available as per EV Bus study in Kolkata by TERI.

All the buses have comfortable interiors with Air Conditioners (AC) provided for maximum passenger and driver comfort.

EV Bus ( 9m Length ) :

  • Length : 9 m
  • Passenger Carrying capacity : 31
  • Battery pack : 125 kWh
  • Driving range at full charge : 130 kms
  • Capital cost : INR 74.9 lacs
  • Battery replacement cost : INR 28 lacs
  • Expected battery life : 10 years
  • Charger availability :
    • Fast charger : 120 kw , Charging Time : 1.5 to 2 hours ( For 0% to 100% state of charge)
    • Slow charger : 60 kw, Charging time : 3 to 5 hours ( For 0% to 100% state of charge)
  • Electricity cost : INR 11 – 12.39 / kWh

EV Bus ( 12m Length ) :

  • Length : 12 m
  • Passenger Carrying capacity : 40
  • battery pack : 188 kWh
  • Driving range at full charge : 160 kms
  • Capital cost : INR 82.5 lacs
  • Battery replacement cost : INR 31 lacs
  • Expected battery life : 10 years
  • Charger availability :
    • Fast charger : 120 kw , Charging Time : 1.5 to 2 hours ( For 0% to 100% state of charge)
    • Slow charger : 60 kw, Charging time : 3 to 5 hours ( For 0% to 100% state of charge)
  • Electricity cost : INR 11 – 12.39 / kWh

Total Cost of Ownership for the EV bus

Analysis :

After accounting for all the aforementioned costs associated with e-buses, the total cost of ownership (TCO) comes out to be INR 45-50/km while the TCO for diesel buses has been found out to be INR 37/km, considering the capital cost of INR 85 lacs for an AC diesel bus.

However, the running cost of the e-buses comes out to be INR 22/km which is one-third of the
same for a diesel bus

Due to falling price of batteries, these electric buses are expected to be commercially
viable within the next 2-3 years in India.

The major drivers behind the implementation of electric buses are the efforts towards reducing air pollution levels and cost-competitiveness of these buses over diesel buses.

Interesting facts :

The e-buses considered for above calculations have been manufactured by TATA Motors at their Dharwad plant, located in the state of Karnatakawhereas

The battery packs (Li-Ion NMC) used in these e-buses have been supplied by Octillion Power Systems, a USA based company having manufacturing units in China.

The chargers have been manufactured and supplied by Tellus Power, China.

The driving range of the 9 m e-buses was also experienced to be lesser than expected (<150 km/ charge) and the range with and without passenger movement was found to be 100 and 130 km per charge respectively
