● Featuring a sleek, wall-style design that is only 400 mm wide, the station runs parallel to the vehicle, minimizing its footprint beyond the parking bay.
● A custom-engineered 3-axis suspension system allows the charging cable and connector to float, making them virtually weightless and effortless to handle.
● An integrated pre-heating function enhances Exponent’s industry-first offboard thermal management system, enabling rapid charging and prolonging battery life even in cold environments.
● The advanced Exponent app provides drivers with real-time, precise updates on charger location and availability.
Bengaluru, 25th August 2025: Exponent Energy, India’s pioneering full-stack energy technology company and global leader in 15-minute rapid EV charging, today unveiled its next-generation P4 charging station. The revolutionary charger combines breakthrough engineering with intelligent design, featuring an ultra-slim 400mm wall-style form factor, weightless floating cables, and the world’s first offboard battery pre-heating system for optimal performance across all weather conditions.
Redefining EV Charging Infrastructure Through Design Innovation
The P4 charging station addresses three critical challenges facing global EV infrastructure: space constraints in dense urban environments, unwieldy charging cables, and battery temperature management across varying climatic conditions. Unlike conventional bulky, box-like charging stations, the P4’s innovative wall design runs along the length of parked vehicles while occupying minimal space beyond standard parking bays.
“At Exponent, everything starts from design thinking. Design isn’t about aesthetics—it’s about rethinking everything from first principles to deliver superior engineering and economics,” said Arun Vinayak, Co-founder and CEO of Exponent Energy. “We made a conscious decision to launch our earlier charger as an MVP to learn from real-world usage. The P4 represents all those learnings combined into our vision for a 360-degree simplified energy experience.”
Revolutionary Engineering Features Set New Industry Standards
The P4 integrates three groundbreaking innovations that address longstanding industry pain points:
Ultra-Slim Wall Design: At just 400mm wide, the P4’s wall-style architecture maximizes space utilization—critical for India’s dense urban environments. This design approach frees valuable real estate while maintaining full charging functionality.
Weightless Floating Cable System: Exponent’s custom-designed 3-axis cable management system eliminates the physical burden of heavy charging cables. The floating mechanism with automatic retraction makes charging effortless for drivers of all ages and physical capabilities.
Offboard Thermal Management: Building on Exponent’s world-first offboard battery cooling technology launched in 2023, the P4 adds pre-heating capabilities. This comprehensive thermal management system pumps coolant and heating through the connector, ensuring rapid charging performance and extended battery life regardless of environmental conditions.
Proven Technology Meets Real-World Application
Delivering up to 40kW of power, the P4 is currently being deployed across Indian cities in partnership with leading OEMs including Murugappa Group’s Montra Electric and Omega Seiki Mobility. This deployment accelerates rapid adoption across both passenger and commercial EV segments while demonstrating the technology’s scalability.
The charging infrastructure features a robust full-metal shell connector designed for India’s challenging conditions, including underwater functionality. Internal optimizations include enhanced airflow design to minimize urban noise pollution and revamped layouts for long-term reliability at scale.
Comprehensive Digital Experience Enhancement
The P4 launch coincides with an upgraded Exponent mobile application providing real-time charger location data, availability status, and seamless payment integration through monthly passes—eliminating the need for keycards or manual transactions. This digital infrastructure complements the physical charging experience to create a truly frictionless energy ecosystem.
Market-Leading Performance and Recognition
Since inception in 2020, Exponent Energy has established remarkable market traction, powering over 2,000 EVs across India while facilitating more than 800,000 rapid charging sessions and enabling over 50 million kilometers of sustainable transportation. The company has expanded operations to six major cities including Delhi NCR, Chennai, Ahmedabad, Kolkata, and Hyderabad.
Exponent’s innovation leadership gained international recognition through its inclusion in the World Economic Forum’s 2025 Technology Pioneers list, which selected 100 early-stage companies from 28 countries driving cross-industry innovation. Additionally, the company achieved a global milestone by introducing 1MW rapid charging technology for buses in August 2024—only the third such deployment worldwide at the time.
Strategic Expansion and Investment Backing
The P4 launch represents a significant milestone in Exponent’s evolution from startup to industry leader. The company has successfully raised $44.6 million across Pre-Series A, Series A, and Series B funding rounds, with backing from prestigious international investors including TDK Ventures, Lightspeed, and Eight Roads Ventures, alongside domestic investors YourNest VC, 3one4 Capital, and AdvantEdge VC.
Strategic partnerships include collaborations with the Motherson Group and the family office of Dr. Pawan Munjal, Chairman and CEO of Hero MotoCorp, positioning Exponent for accelerated market expansion and technology development.
Global Scalability with Indian Innovation
The P4 charging station exemplifies Exponent’s “Built in India, for India and the world” philosophy, combining local engineering expertise with global scalability requirements. The technology addresses universal EV charging challenges while incorporating solutions specifically designed for Indian market conditions and infrastructure constraints.
