Breaking Barriers to EV Adoption:

Exponents’ founders, Arun Vinayak and Sanjay Jagannath, address key challenges hindering EV adoption: charging time, battery life, and cost. Their technology, already proven in real-world use, offers a compelling solution:

  • 15-minute rapid charging: Eliminates range anxiety and enables swift on-the-go refuelling for last-mile delivery fleets.
  • 3,000-cycle lifespan: Extends battery life, reducing costs and environmental impact.
  • LFP cell compatibility: Leverages cost-effective and readily available batteries, making rapid charging accessible.

A Partnership for Progress:

TDK Ventures recognizes the game-changing potential of Exponent’s technology and its alignment with their vision for a cleaner, electrified future.

  • Nicolas Sauvage, TDK Ventures President, highlights Exponent’s “economical and scalable” solution as a revolutionary step towards broader EV adoption.
