EV scenario in India The position in which India stands right now needs to have a systematic EV program in place to keep up with the global standards and policies. Potential growth in EV has possibilities for developing a leadership role in this segment. As electrification is the major emerging trend amongst the Auto industries, they have plans for Electric vehicles and their technology. Before COVID-19, as per Niti Aayog, the EV penetration could reach 80% for two-wheeler and 30% for private cars. If India manages to reach its target by 2030, it could save about 1 Giga tonne of emissions. Looking at the pollution level in major Indian cities, it is the need of the hour.
Post-Lockdown Scenario for Electric Vehicle Before covid, the Indian auto industry was already in peril to keeping up with the BS-VI emission norms And it became worse when the complete nation was hit with a lockdown keeping in mind the increasing number

of cases and extension of lockdown further added to its woes. Somewhere around chaos, India could seem to be losing its E.V. momentum. Also, some of the industry leaders indicated that the cost of an Electric vehicle as compared to a conventional vehicle because India is one of the most cost dependent market. Also, the threewheelers which is a sizable chunk of the electric vehicle segment right now took a major blow because of the concept of social distancing After this, our Prime Minister started vocal for local initiative and taking a closer look if our businesses are much more dependent on china rather than each other; it would make much sense financially logistically and also will help in future-proofing. Keeping the same in mind I thought of alternative electric vehicle technologies that will diminish our dependencies on china or any other country. So, let’s start looking at this objectively an Electric Vehicle can be divided into four major Component those are 1. Motor
2. Battery 3.Controller/drive & BMS 4. Telemetry System The last two components are either designed here or assembled here to completely remove dependency from china for these kinds of products we should at least have fabrication unit to manufacture the required ICs. So, from this point forth our discussion will only be concentrated to moto, batteries and their alternate technologies
MOTOR Motor for an electric vehicle can be classified into the following categories. Based on the above classification major market share for an electric vehicle are leaning towards 1. DC Series Motor These motors are mainly used for traction applications as high starting torque capabilities. Also, the major advantage for these types of motor is comparatively easier speed control techniques, and the ability to withstand sudden increment in
