Summary

Bengaluru-based EV energy company Exponent Energy has raised ₹200 crore ($21.1 million) in a funding round co-led by 360 ONE Asset and TDK Ventures.

BENGALURU, June 10, 2026 — Exponent Energy has secured ₹200 crore ($21.1 million) in a funding round co-led by 360 ONE Asset and TDK Ventures as the company accelerates the expansion of its commercial electric vehicle charging ecosystem across India. The latest investment will support geographic expansion, new vehicle category deployments, and continued research and development. 

The round marks 360 ONE Asset’s first investment in the electric vehicle sector and Hitachi Ventures’ first investment in India’s energy sector. Existing investor TDK Ventures also increased its stake through a follow-on investment. Other investors participating in the round include Eight Roads Ventures, Lightspeed, 3one4 Capital, AdvantEdge VC, and YourNest, which invested an additional $4 million through its Continuum Fund. 

With the completion of the round, Exponent Energy’s total funding since its founding in 2020 has reached $65.7 million. The company was established by former Ather Energy executives Arun Vinayak and Sanjay Jagannath and has focused on developing rapid-charging technology for commercial electric vehicles. 

Building an integrated EV energy platform

Exponent Energy is expanding beyond charging infrastructure to create a broader commercial EV ecosystem. The company operates through three core pillars: its proprietary charging and battery technology, the Exponent OTO mobility platform, and Exponent ONE, a financing and asset-management business designed to support fleet electrification. 

To strengthen its financing operations, Exponent appointed Sandeep Divakaran, formerly associated with Greaves Electric Mobility’s financing business, as Co-founder and CEO of Exponent ONE. The division focuses on addressing financing barriers that often slow commercial EV adoption. 

According to Sumit Jain, Head of Venture Growth Investments at 360 ONE Asset, Exponent’s integrated approach helps fleet operators reduce ownership costs while improving operational efficiency and charging reliability. 

Focus on rapid charging and interoperability

Exponent Energy is best known for its proprietary energy stack, which combines battery packs, charging systems, and connectors to enable compatible commercial EVs to achieve a full charge in approximately 15 minutes using standard lithium-ion cells. The company also offers a 3,000-cycle battery life warranty. 

A key feature of the platform is interoperability. Vehicles equipped with Exponent’s battery system can use the company’s rapid-charging stations while also retaining the flexibility to charge through conventional public charging infrastructure or depot-based charging networks. 

Commenting on the funding, Arun Vinayak, Founder and CEO of Exponent Energy, said the company spent its first five years building and validating its rapid-charging technology and is now entering a growth phase focused on scaling commercial EV adoption across India. 

The company plans to expand its presence beyond its existing markets and deepen its footprint in commercial mobility segments as electric vehicle adoption continues to accelerate.
