KERS-ONE: Developing a KERS Module for Retrofitting City Buses

A System Prototyping Research and Development Programme

Fuel Consumption in City Driving

City driving is often characterized by repeated braking and accelerating. This often wastes a lot of energy. Studies by the US EPA have shown that only a small part of the energy generated from fuel is actually used to drive the wheels - about 15% ! Of this nearly 7% is wasted due to braking. In theory recovering energy from braking can improve fuel efficiency by almost 80% !


State road transport corporations spend thousands of crores of rupees on fuel bills each year. The APSRTC spends over Rs 2,000 crores on fuel consumption each year. Even a 5% increase in fuel efficiency of its vehicles can save upto Rs 100 crores each year, leading to lowered bus fares for the citizens.

Clean Transportation A Beginning

Every country, state or district has its own unique road and driving conditions. Often technology solutions developed to suit these specific situations can deliver superior value for a lower price. Good news is that such solutions can be modeled using a system prototyping platform such as SANKHYA Teraptor. Sankhya Technologies is using the Teraptor Automotive Channel SPP to model different technologies for improving fuel efficiency.

KERS-ONE Overview

The research program has the phase-1 goal of developing a KERS system for buses that can offer a 5% increase in fuel efficiency for buses plying in city conditions. Here are the key milestones:

SNO Milestone Duration Description
1 Build System Model 12 Weeks Use SANKHYA Teraptor to create a system model
2 Shortlist Solution Alternatives 8 Weeks Use model to study various alternatives and identify 2-3 shortlisted alternatives
3 Build Physical Prototype 12 Weeks Build a physical prototype using a bus taken on loan from road transport corporation
4 R&D Report 12 Weeks Repeat Steps 1-3 to create a working prototype as necessary. Create a report and submit to transport operators


Sankhya Technologies is inviting collaborators interested in participating in this programme. Please contact for programme entry criteria, benefits and programme fees.
