The context: National Electric Mobility Mission
The Indian Government has set up ambitious targets to ensure that electric vehicles (EVs) replace fossil fuel-based vehicles as the primary mode of transport…. India stands at the cusp of a ground-breaking revolution in Electric Mobility (https://e-amrit.niti.gov.in/home).
Driven by the commitment to Go green… Go electric….The benefits: Why Your Next Car Should be Electric:
- Lower annual running and maintenance cost.
- Reduction in carbon footprint: Zero Tailpipe Emissions.
- Tax and financial benefits.
- Transition from fossil fuel's toxic emissions.
- Easy to drive and silent functioning capability.
- Convenience of home charging.

Unveiling an Era of Green Charging Infra
We take a holistic approach towards developing EV batteries, making more sustainable and user-friendly systems. The main focus is to improve the life of the battery and to monitor the ageing of battery packs. Research in a thermal management system, digital twin for batteries, real-time monitoring using multi-physics and machine learning-based models are also developed to achieve the aforesaid focus. At the corner, Solar Charging will also be explored.
