Exponent Energy, an Indian energy-tech startup, has launched its next-generation electric vehicle (EV) charging station, codenamed P4, offering rapid 15-minute charging alongside a streamlined design that prioritises space efficiency, user-friendliness, and battery life extension. The P4 introduces three major innovations: a slim wall-mounted design (just 400 mm wide) that runs parallel to parked vehicles, floating cables with a 3-axis suspension for effortless handling, and offboard thermal management with pre-heating to ensure charging reliability in colder climates.

Co-founder and CEO Arun Vinayak said the design reflects Exponent’s commitment to first-principle engineering that combines aesthetics with robust performance and cost-efficiency. The P4 delivers up to 40 kW of power and is already being deployed across Indian cities with partners such as Montra Electric (Murugappa Group) and Omega Seiki Mobility, catering to both passenger and commercial vehicles.

Built for durability, the P4’s connector features a full-metal shell with axial sealing technology similar to LPG and CNG nozzles, enabling functionality even in waterlogged environments. Enhanced internal airflow keeps fan noise low, while a redesigned interior layout improves reliability under intensive usage. The station is integrated with the Exponent app, which enables users to locate chargers, check availability, and use seamless monthly billing—removing the need for keycards or manual payments.

Since its founding in 2020, Exponent has enabled over 800,000 rapid charging sessions across 2,000 EVs, powering more than 50 million kilometres of emission-free travel. In 2023, it became the first Indian firm—and the third globally—to roll out 1 MW rapid charging for electric buses.

Recognised on the World Economic Forum’s 2025 Technology Pioneers list, Exponent has raised Rs 3.72 billion ($44.6 million) from investors including TDK Ventures, Lightspeed, Eight Roads Ventures, and Indian firms such as 3one4 Capital and YourNest VC.

With the launch of P4, Exponent aims to set a new global standard for scalable, smart, and robust EV charging infrastructure.
