E-Rickshaws are popular and convenient mode of transportation for last mile connectivity and are typically used for short distance (<10 Km) commute. As per recent reports there are more than 1.5 million e-rickshaws plying on Indian roads and approx. 10,000 vehicles are adding every month. Owners of these vehicles are inclined towards the overall range these vehicles can give on a single charge. Range can be improved by using efficient powertrain. Range can also be improved by optimized Battery Management systems and Controllers. Though there are certain evaluation criteria (such as curtailed Indian Drive Cycles) which can be used for efficiency estimations, manufacturers are more interested in extending the range in real world scenarios. Hence, the availability of real-world drive cycle is imperative. Through this paper, we have attempted to derive a typical drive cycle by collecting road data of various types of e-Rickshaws under different environment conditions.

E-Rickshaws are receiving considerable attention as a sustainable passenger transportation in Indian mobility space. As per the recent reports, more than 1.5 million e-rickshaws are currently operating in the country. These are quieter, cleaner and convenient mode for last mile connectivity and are typically used for short distance (<10 Km) commutation. For owners, these vehicles offer value in terms of affordability and operating cost. Challenge for manufacturers is to design a vehicle which balances the requirements of both passengers and owners. Energy efficiency (Energy consumption per Km) influences such critical decisions. There is always a difference between the catalog value and actual on-road Energy efficiency figures and therefore it's important to really understand owner requirements w.r.t. market where vehicle is going to be operated.
