Circuit S Electric Bus

The Circuit S e- Bus is a zero-emission vehicle, an assurance of a positive, cleaner and greener future for all of us and for the generations to come. It is built to match the country’s unique transport need that is powered by the swappable Smart Battery technology. The Circuit bus is designed keeping in mind the Indian road conditions, the prevailing usage, load conditions and landscape. The driver cockpit is designed to lower driver fatigue and ensure a comfortable drive. Designed with utmost attention to aesthetics and ergonomics, the 31-seater Circuit offers a relaxed commute, and the near noiseless travel adds to passenger comfort. In terms of maintenance, the Circuit bus will not spring surprises that a diesel bus could, contributing to the paradigm shift in public transportation in India. This Circuit-S bus ranges from 9m to 12m, uses light-weight, small batteries which are quickly interchangeable, requires less maintenance, and provides more passenger room. 
The Circuit-S e-bus has a removable battery that can be automatically swapped out for a freshly charged one in less than 4 minutes. Each battery pack is about 1/4th the weight (improving efficiency) and smaller (freeing up passenger space) than a typical bus battery. The reduction in battery size and weight is due to the fact that it is a lower capacity battery that gets swapped out frequently. The range of each battery pack is 50 km. These buses will be sold without the battery included - which makes the upfront cost of the Circuit-S bus equivalent to that of a regular diesel bus. The bus operators then use the swappable batteries on a pay-per-use basis. A network of Quick Interchange Stations will be set up to facilitate the swapping, charging and maintenance of battery packs. 
The project also breeds the idea of eliminating the battery from the entire cost of an electric bus, thus bringing an EV on par with its diesel counterpart in terms of the total cost per kilometer of the distance travelled, while also making the STUs asset-light in their books.  The smart batteries involved are lightweight and are connected over the Cloud, enabling the option of pay-as-you-go to the Circuit-S model, based on the amount of charge consumed at the end of a trip. The batteries are modular, which encourages the use of smaller batteries in vehicles. Thus, being lighter, they also enable OEMs to better manage the challenge of battery temperature control, even when the ambient temperature in the country hovers in the higher range of around 450 Celsius. The smart batteries also help the company perform swaps on all buses from the same interchanging station.
Ashok Leyland has bagged its first major electric bus order, for the supply of 50 buses to the Ahemdabad Bus Rapid Transit System. The electric buses are expected to start plying on the BRT corridor by the last quarter of this fiscal year.
