After the huge success of the Grand Challenge, state-owned Convergence Energy Services Limited (CCESL), supported by WRI India, has accelerated the relinquishment of electric motorcars under phase 1 of the National Electric Bus Program with a tender for 465 electric motorcars across six countries and the Union. As the number of e-buses increases, it’s vital to understand the dynamics surrounding range (the total kilometres an e-bus can run on a single charge), charging systems, and charging duration. This blog sheds light on the range conditions of e-buses on a single charge and their diurnal functional conditions, grounded on recent procurement tenders and analysis of data from Ahmedabad, Bengaluru, Delhi, Mumbai, Pune, and Surat. For a grainy understanding, we also looked at analogous datasets from global metropolises like Barcelona, Berlin, Copenhagen, London, Milan, Paris, Prague, Shenzhen, and Vienna.
Crucial Compliances From Recent Indian Tenders Historically, Indian conveyance agencies have sought a higher range (oon a single charge) for 9-cadence buses than their 12-cadence counterparts. In utmost cases, agencies prefer 12-cadence buses with a lower range (on a single charge) than they need for diurnal operations. In recent tenders, conveyance agencies have increased their range of conditions from a single charge. For example, in Mumbai’s tender for 340 e-buses floated in December 2019, the Mumbai Electric Supply and Transport Undertaking (Stylish) sought to land 12- and 9-cadence e-buses with a range of 120 km on a single charge and a diurnal functional distance of 140–170 km. Range conditions for 12- and 9-cadence buses were later increased to 250 km and 170 km, respectively. This change was intended to reduce dead kilometres (non-revenue kilometers) and ameliorate machine application. Also, in the subsequent tenders, the cost per kilometre rate was reduced by 30, despite the fact that the three-bus range increased, because the cost per kilometre is more dependent on diurnal machine application than on a single charge range. International Case Studies: A Many transnational metropolises were examined with a focus on bus range and functional kilometres to better understand bus operations encyclopedically. In most of these cities, range demand exceeds diurnal functional demand with different charging systems. Other parameters such as battery storage capacity, charging type, and event charging provision were also investigated (as shown in Table 1).
