To study and compare communication protocol for fast charging in electric two-wheeler with respect to CCS 2.0: An Indian Perspective

India, as the world’s largest two-wheeler market, is witnessing an aggressive transition towards electric mobility, driven by urban air quality concerns, fuel cost sensitivity, and government incentives. Among the critical enablers of this shift is the availability of robust and efficient fast charging infrastructure tailored to electric two-wheelers. This paper proposes a systematic testing framework for fast charging of electric two-wheelers, addressing key parameters such as battery thermal management, charging communication protocols, safety interlocks, and State of Charge (SOC) estimation accuracy. The study evaluates current and emerging standards, including AIS-156, IS 17017, and IEC 61851, and identifies gaps specific to two-wheeler applications such as compact form factor constraints, lower energy storage, and high operational turnover in fleet usage. A special focus is placed on interoperability, user safety, and infrastructure scalability for dense urban environments. The findings aim to support policy formulation and encourage the development of standardized, efficient, and safe fast-charging ecosystems for India’s electric two-wheeler revolution.
