Tata Mo­tors starts tri­als of elec­tric bus in Guwa­hati

Auto components India - - CONTENTS -

Tata Mo­tors has com­menced tri­als of its 9-m elec­tric bus in Guwa­hati. With a seat­ing ca­pac­ity of 26-34 pas­sen­gers, the full-auto trans­mis­sion Tata Ul­tra elec­tric bus was flagged off by Anand Prakash Ti­wari, Man­ag­ing Di­rec­tor, As­sam State Trans­port Cor­po­ra­tion (ASTC), on Oc­to­ber 16, 2017, making it the first state trans­port un­der­tak­ing (STU) in East­ern In­dia to start tri­als of an elec­tric ve­hi­cle. The STU in col­lab­o­ra­tion with Tata Mo­tors will run the tri­als for 7 days.

This trial follows the suc­cess­ful tri­als of the 9-m elec­tric bus from Par­wanoo to Shimla a few months ago, where the bus cov­ered 160 kms in one full charge. Tata Mo­tors said tri­als in Chandi­garh also showed ‘very en­cour­ag­ing’ re­sults in a run­ning of 143 kms, cov­er­ing ap­prox­i­mately 70% of the charge. These tri­als are part of the Min­istry of Road Trans­port’s agenda for the elec­tri­fi­ca­tion of pub­lic trans­port, for which Tata Mo­tors is get­ting ready with its range of elec­tric ve­hi­cles, from 9 meters to 12 meters with var­i­ous seat­ing con­fig­u­ra­tions, as well as its last mile pas­sen­ger trans­port ve­hi­cle, the Tata Magic Iris.

A K Jin­dal, Head, En­gi­neer­ing Re­search Cen­tre, Tata Mo­tors, said, “These buses qual­ify for the sub­sidy un­der re­vised FAME scheme which will give a big boost to the elec­tri­fi­ca­tion of pub­lic trans­port. Tata Mo­tors is also work­ing with var­i­ous study groups formed by the cen­tral gov­ern­ment to work out var­i­ous busi­ness mod­els for op­er­at­ing elec­tric ve­hi­cles and to op­ti­mise the over­all eco­nom­ics of these buses, for a truly Make in In­dia so­lu­tion.”

Tata Mo­tors has taken ma­jor steps in hy­bridi­s­a­tion and elec­tri­fi­ca­tion of pas­sen­ger trans­porta­tion and has de­vel­oped tech­nolo­gies for hy­brid and elec­tric ve­hi­cles. It has also de­vel­oped al­ter­na­tive fuel tech­nolo­gies such as CNG, LNG, Bio-CNG, Bio-Diesel and Fuel Cell. The elec­tric ve­hi­cle de­vel­oped on proven bus plat­forms also of­fers re­gen­er­a­tive brak­ing which re­cov­ers be­tween 25 to 35% of the brake en­ergy.

The elec­tric buses are equipped with a highly ef­fi­cient drive train and weight-op­ti­mised bat­tery, cou­pled with Tata Mo­tors pro­pri­etary en­ergy man­age­ment sys­tem and ve­hi­cle con­trol strat­egy for a low to­tal cost of ownership. The EV bat­tery pack is op­ti­mised to avoid com­pro­mise on the pas­sen­ger ca­pac­ity prov­ing the best ef­fi­ciency in KWHR/KM. The EV bat­tery is liq­uid cooled and spe­cially de­signed for In­dian tem­per­a­ture con­di­tion thus pro­vid­ing a higher bat­tery life along with highly ef­fi­cient per­for­mance. The roof mounted bat­tery pro­vides safety from wa­ter log­ging of elec­tri­cal equip­ment. The range of the buses can be en­hanced with smaller bat­tery pack to 200 to 240 km with op­por­tu­nity charg­ing. The elec­tric bus is also loaded with fea­tures such as mul­ti­plex wiring sys­tem, au­to­matic tick­et­ing / smart card-en­abled sys­tem, ITS-en­abled and re­verse cam­era as­sist etc. which can be fit­ted on cus­tomer re­quest. Tata Mo­tors claims that it is In­dia’s first OEM to get ARAI and ho­molo­ga­tion cer­ti­fi­ca­tion for 9m and 12-m elec­tric buses.
