Tata Motors will supply 80 Electric buses to the West Bengal Transport Corporation (WBTC). The company has already supplied 20 units of Ultra Electric 9/9m AC E-buses, with remaining 20 9/9m AC E-buses scheduled to be delivered by March 31, 2019. In addition, the home-grown automaker will also be delivering 40 9/12m AC E-buses to WBTC in a phased manner. Hon’ble Chief Minister of West Bengal Mamata Banerjee, flagged off the buses with dignitaries from WBTC and Tata Motors. The new buses will begin their inaugural journey from Nabanna, Howrah.
Manufactured at Tata Motors Dharwad plant, the Ultra Electric buses will have a traveling range of up to 150 kilometers on a single charge. The company has installed charging stations at Nonapukur, Kasba, Newtown and Belghoria. Furthermore, intermediate charging terminals powered with fast charging are mounted at Howrah and Santragachi. The Li-ion batteries have been placed on the rooftop to prevent breakdown due to waterlogging. The batteries are liquid cooled to maintain the temperature within an optimum range. The critical electrical traction components have been sourced from internationally known best-in-class suppliers in USA, Germany and China offering proven products.
The new age Ultra Electric buses, powered by an Integrated Electric Motor Generator are built on existing proven platforms of Starbus and Ultra. With a max power of 245KW and continuous power of 145KW, the buses have a seating capacity of 31 + 1D seats. The buses will help in zero tailpipe emissions, 50% lower fuel costs, 20% better energy consumption and lower maintenance downtime as compared to diesel buses. The Ultra Electric buses are air-conditioned, have modern interiors and comfortable seats for 31 passengers. As an industry first, there will be air suspension for both front and rear axles to make travel more comfortable for the commuters. Integrated electric motor generator with a peak power of 333HP can deliver 197HP.
Dr. A.K. Jindal, Head Engineering (Electric & Defence), CVBU, Tata Motors said, “Tata Motors has been engaging in advanced engineering and development of electric traction system for Hybrid as well as Pure Electric vehicles for over a decade. The Ultra Electric Bus is a new modular platform, which has been developed in a very short lead-time of less than a year, leveraging the knowledge and experience we have gained and demonstrating our commitment to the Government of India’s National Electric Mobility Mission Plan for Public Transport. The architecture of the platform has been conceived and developed by in-house engineering team of Tata Motors, meeting the requirement of various tenders floated by different state transport undertakings. The exterior has been designed with new brand identity that includes stylized Ultra headlamps and streamlined looks. The vehicle architecture ensures very low energy consumption and low TCO (total cost of operation) apart from being a Zero Emission environment friendly bus.”
