India's electric vehicle transition is less a clean energy story and more a question of national energy resilience, according to Arun Vinayak, Founder and CEO of Exponent Energy. Speaking in an interview with journalist Prerna Lidhoo, Vinayak made the case that India must treat EV adoption as a strategic imperative, particularly in the commercial vehicle segment.
Commercial vehicles, Vinayak noted, account for close to 70% of on-road energy consumption in India. Electrifying this segment, he argued, should take precedence over the passenger vehicle market, given the economic weight it carries and the fuel import exposure it represents.
The West Asia crisis, he said, had already demonstrated the geopolitical risks embedded in India's dependence on oil imports, and had driven a measurable surge in demand for electric alternatives. The disruption, in his view, underscored the urgency of localising EV supply chains rather than replicating the import dependencies that currently exist in fossil fuel markets.
Central to Exponent Energy's approach is ultra-fast charging, which Vinayak positioned as a prerequisite for commercial viability in the fleet and logistics sector, where vehicle downtime directly affects operator revenue. He also pointed to retrofitting—converting existing internal combustion engine vehicles to electric—as a practical tool to accelerate adoption without waiting for full fleet turnover cycles.
Standardisation, however, remains a significant obstacle. Vinayak identified the proliferation of competing technology pathways as a factor undermining investor confidence, with financiers reluctant to commit capital in the absence of clear, uniform technical standards across the sector.
On the commercial opportunity, Vinayak put the addressable market for commercial EV energy in India at $90 billion. Realising that potential, he said, would require closer collaboration between EV companies and financial institutions to structure products that make electric fleets accessible to fleet operators.
Exponent Energy is also preparing to extend its focus to intercity electric buses, a segment Vinayak sees as a natural next step given the scale of inter-city freight and passenger movement in India.
Exponent Energy was founded to develop energy systems for commercial electric vehicles, with a focus on fast-charging infrastructure. The company operates in a market where electric penetration in the commercial segment remains low relative to passenger vehicles, even as government policy has increasingly prioritised fleet electrification through schemes such as the PM e-Bus Sewa programme.
