he last six months have been quite turbulent for the automotive industry globally, especially in India. These challenging times have given the industry an opportunity to evaluate and reprioritize the technological initiatives that could pave the way for the future. Electrification, which is one of the disruptive technologies for the automotive industry, is expected to see significant acceleration in localization. Some studies estimate the electric vehicle market to value around `500 billion by 2025. Two-wheeler and three-wheeler market may see significant adoption with more than 20%, followed by

e-buses, which maybe around 13%. Light commercial vehicles may see a modest adoption in the medium term, but will ramp up as the infrastructure starts to settle in. To meet the growing market demand, the engineering team in these organizations must combine speed with a strong commitment to deliver the product promise of reliability and performance. Engineering simulation has played a key role in enabling OEMs to realize these product promises. 3D simulation has established itself as a standard practice for detailed design of the components across the physical domains. CFD simulations have helped engineers to maintain the
battery temperature within safe and reliable limits with optimized cooling system. Computational electromagnetics has been instrumental in ensuring the performance and validity of electric machines. Virtual pre-compliance testing for EMI EMC reduces the number of prototypes required to certify the product. Multiphysics simulations have helped engineers to understand the complex interactions of the different physical domain. 3D simulation, even though very powerful, cannot extend beyond component design as it cannot account for interactions with the control software and hence system performance
