Electric vehicle (EV) ecosystem in India is at its initial stages of development. The Indian Governments is very clear where in they want auto manufactures to shift from conventional IC engines to Electric Motor driven vehicles. Keep the same objective in mind central government has announced the second phase of its ambitious FAME (Faster Adoption and Manufacturing of (Hybrid) and Electric Vehicles) policy and aims to step up EV adoption in the country across segments. The Indian higher education system have to move to create experts in this new emerging area.
EV manufactures who are looking for professionals are Hero Electric, Tata Motors, Ather Energy, Mahindra Electric, Lohia Auto, TwentyTwo Motors, BYD Olectra, Hyundai Kona electric, Ashok Leyland, MG Motor and many more.
Looking at this huge potential demand of professionals, Automobile Engineering Department at Manav Rachna has included two courses Electric Mobility & Hybrid and electric Vehicles as a part of their regular programme. The courses include topics such as lithium and sodium ion battery components., motor and their controls, battery chargers, methods of charging, motor torque requirement & calculations, battery charging stations, battery swapping stations and electric power trains.
Required Technical Expertise
As an expert, it is required to have knowledge about the different resistance acting on the movement of the wheels and based on that requirement of the torque from the motor for its selection. Controlling of motors through controllers and DC Choppers is required because moving vehicle has to have frequent variations in speed.
Presently about 40% EV cost is of the batteries which act as a energy storage hub and will replace conventional fuels in near future. Knowledge of their electrochemistry and energy storage capabilities i.e energy density are the domain areas where experts will be required in future both for operational and research purpose. Lithium and cobalt metal which act as a raw material for battery are not found in India. Again we have to remain depend on countries such as China, Bolivia, Chile etc which have huge reserves of these metal. Reports indicate that China has developed Li ion technology because it suits well for them. But if we look from Indian perspective Sodium (Na) ion batteries are best suited for our needs since Na is easily available in India. An embedded microcontrollers design for batteries is another highly specialized area where expertise will be required for new indigenous product development.
Battery charging technology and development of charging stations will require professionals. New designs will required for electric vehicle service equipment (EVSE). The system is an intermediary between a power source and the vehicle’s charging port, and is typically mounted on a wall or up on a pedestal. Its role is to simply transfer the AC power to the vehicle safely. EV Charging has different levels 1 2 & 3 for slow and fast charging. On board chargers for level 1 & 2 are devised by the company themselves. Japanese CHAdeMO chargers, SAE, Combo Charging System & Tesla’s Super Charger are motivating Indian companies to device indigenous systems. Mobility Design & esthetics are some areas where EV design section is working hard.
It has been observed from research that 60 % of customers buy vehicles based on design, aesthetics, space available, infotainment features, internet connectivity and self-driving mode features wherein EV design experts are required.
