Whereas each electrical passenger car (PV) and electrical two-wheeler gross sales have been at all-time highs in October 2022—at 3,745 items and 75,294 items, respectively, in keeping with information by authorities’s web site Vahan—their share share is minuscule.
Electrical PVs, for instance, fashioned simply 1.29% of the entire 291,113 PVs bought in October 2022, and electrical two-wheelers fashioned simply 4.77% of the entire 1,577,694 two-wheelers bought.
Shailesh Saraph, EVP & international head, ER&D, Tata Applied sciences, advised FE that whereas there are market challenges that should be overcome for higher uptake of electrical autos, there are specific expertise challenges as properly, which Tata Applied sciences—a subsidiary of Tata Motors—is making an attempt to beat.
Saraph mentioned that the electrical automotive structure itself is present process a change; for instance, in inside combustion engine autos, the engine is often within the entrance (and on the rear in some automobiles), however in electrical automobiles the battery is positioned below the ground space, and the place for the engine and the gearbox could be utilised for different functions. “Some carmakers try to do chassis integration of the battery and, within the course of, launch a very new platform,” he mentioned. “The second problem is about battery manufacturing in India at scale, however many firms are actually working in direction of that.”

Vary anxiousness (fear that the battery will run out of energy whereas driving) continues to be a problem, however there are answers to minimise it. Battery swapping, even in electrical PVs, is doable, as has been proven by Chinese language carmaker NIO. “We have now labored with NIO for his or her three-minute swap and created a self-aligning battery swap with them. Fail-safe mechanisms are put in place and the PV battery swapping takes nearly the identical time because it takes to fill a petrol tank,” Saraph mentioned.
Saraph mentioned that lithium-ion batteries have nearly reached the top of technological improvement, and so higher driving vary in electrical two-wheelers could be achieved by options resembling battery swapping and detachable batteries.
Electrical business autos
Not like electrical PVs and electrical two-wheelers, business autos (CVs) will want a hybrid resolution as a substitute of purely electrical. “Small CVs that function in a closed loop can simply be turned electrical and operated profitably, however heavy CVs which are used for long-distance journey will want a hybrid resolution,” Saraph mentioned. “It may be battery plus gasoline or battery plus hydrogen. Hydrogen gasoline cell can be a promising expertise for electrical CVs.”
In a hydrogen gasoline cell, as a substitute of utilizing electrical energy to separate water into hydrogen and oxygen, these two components are mixed to supply water and electrical energy. The electrical energy is then used to drive the car’s motor, and water is the one waste produced.
Tata Motors can be experimenting with options resembling utilizing hydrogen inside the prevailing inside combustion engine (which makes use of diesel and petrol/CNG as fuels) to energy its vehicles and buses. This expertise is named hydrogen inside combustion engine (H2ICE).
Lastly, Tata Applied sciences has developed a 5R (decreasing) methodology to facilitate light-weighting (proper materials, proper place, proper price, proper efficiency and proper amount), which permits prospects (OEMs) to scale back car weight.
Saraph added that whereas automakers and automotive researchers are doing their greatest at assembly each market and technological challenges posed by the shift in direction of electrical mobility, customers of EVs can enhance vary by double-digit share simply by extra environment friendly driving habits, resembling not letting the battery discharge an excessive amount of, charging it at dwelling utilizing gradual charger, not accelerating too typically and utilizing as a lot regenerative braking as potential.
