JBM So­laris dis­played a 12 m Eco-Life elec­tric bus. Jointly de­vel­oped by JBM Auto and Euro­pean e-mo­bil­ity spe­cial­ist, So­laris Bus and Coach S.A., through a joint ven­ture, the EcoLife city bus is 100 per cent elec­tric, and man­u­fac­tured at Faridabad. Hav­ing a cor­ro­sion re­sis­tant mono­coque struc­ture and alu­minum side pan­els for higher rigid­ity and high tor­sional stiff­ness, the bus has been de­signed as per the Euro­pean stan­dards and fol­lows the safety norms for frontal col­li­sion, roll over and side im­pact. Em­ploy­ing high strength glass fi­bre com­pos­ite parts at the front, rear and top, the bus em­ploys an in­verted por­tal axle. The de­sign al­lows for more room in­side. Sus­pen­sion is pneu­matic, and is elec­tron­i­cally con­trolled. Front sus­pen­sion is in­de­pen­dent. The rear has dou­ble pneu­matic springs cou­pled with an anti roll bar. Ex­pected to save 3.5 lakh litres of diesel over ten years of op­er­a­tion, the Eco-Life bus is claimed to save 959 equiv­a­lent tonnes of car­bon diox­ide.

The di­rect drive elec­tric pow­er­train gets a trac­tion mo­tor that de­liv­ers 160-215 kW power and has been de­signed to in­ter­face with stan­dard rear dif­fer­en­tial with­out re­quir­ing an in­ter­me­di­ate gear­box. Based on the traf­fic con­di­tions, the Eco-Life bus is claimed to have a range of 150-200 kms over 10-15 hours of city bus op­er­a­tions. At the heart of drive sys­tems are four-pole asyn­chro­nous trac­tion mo­tors and lithium ion bat­ter­ies con­trolled by trac­tion con­troller and bat­tery man­age­ment sys­tem. The de­sign is such that the bat­ter­ies feed the trac­tion con­troller which in turn con­trols the trac­tion mo­tor. Pow­ered by the fast charg­ing lithium ion bat­ter­ies, the bus can be recharged through a pan­to­graph and plug-in sys­tems, al­low­ing the bus to opt for dif­fer­ing in­fras­truc­ture that the op­er­a­tor might pos­sess.

The com­po­nents that are con­ven­tion­ally fed by com­pres­sors, pow­ered by an in­ter­nal com­bus­tion engine, have been re­placed with elec­tric coun­ter­parts in the Eco-Life. The bat­ter­ies thus are no longer an elec­tric en­ergy source for the mo­tors only, they are also a source of en­ergy for the aux­il­iary sys­tems in­clud­ing HVAC sys­tem, air com­pres­sor mo­tor and power steer­ing mo­tor through a High Volt­age Switch­ing Sta­tion (HVSS). Stat­ing that In­dia has close to 80,000 buses which should con­vert to elec­tric in the next eight years, Nis­hant Arya, Ex­ec­u­tive Direc­tor, JBM Group, ex­pressed that they are look­ing at var­i­ous de­vel­op­ments where the gov­ern­ment’s prime fo­cus is on pub­lic trans­porta­tion. “We will soon launch a nine-me­ter elec­tric bus,” he said.
