Exponent Energy, an innovative Bangalore-based EV technology startup, has launched its next-generation P4 EV charger capable of delivering full charging in just 15 minutes. This breakthrough marks a significant advancement in fast charging technology, designed to overcome traditional limitations on battery life and overheating, creating an efficient and sustainable EV charging experience for Indian and global markets.
Redefining Fast Charging With Advanced Technology
- Unlike conventional fast chargers relying on high-voltage systems, Exponent Energy’s P4 charger uses advanced liquid cooling technology that circulates coolant around the battery cells, maintaining battery temperature below 15°C even under rapid charge.
- This cooling innovation protects battery health, making the charger capable of supporting 3000+ charging cycles without significant degradation, a major step beyond the typical rapid chargers that drastically shorten battery life.
- The P4 charger is compact, measuring just 400 mm in width and delivers up to 40 kW power, setting a new standard for scalable and affordable rapid charging solutions.
Comprehensive Energy Stack For Sustainable Mobility
Exponent Energy offers a full-stack solution encompassing battery packs, the P4 fast charger, and all required management systems engineered to provide a seamless strategy from power delivery to battery health optimization. Key components include:
- e^pack Battery: Proprietary long-lasting LFP cells designed specifically for extreme rapid charging.
- e^pump Charger: Seamlessly integrates rapid charging capabilities with dynamic algorithms optimizing energy flow based on real-time battery condition.
- Battery Management System and Virtual Cell Model: Continuously adapts charging to individual battery cell conditions, maximizing battery longevity.
- Offboard Thermal Management: Pumps coolant from the charger directly into the battery, efficiently extracting heat during the 15-minute charge.
Breaking Charging Time vs. Battery Life Tradeoff
Traditional fast chargers increase battery temperature, significantly reducing life expectancy to just a few hundred cycles. In contrast, Exponent Energy’s system achieves:
- Rapid charging times (15 minutes for substantial energy top-up)
- Superior battery longevity with a 3000-cycle warranty, certified by TUV India Pvt. Ltd.
- Full compatibility with regular LFP cells ensuring cost-efficiency and future scalability to new battery chemistries.
Impact on EV Ecosystem and Future Outlook
- The P4 charger is designed for broad applications, from autorickshaws to buses, allowing rapid charging tailored for varying vehicle sizes.
- By lowering charging times and extending battery life, Exponent Energy’s technology significantly reduces operational costs, making EVs more viable for commercial fleets and public transportation.
- The 15-minute rapid charge capability opens pathways for widespread EV adoption across India’s urban and rural areas, supporting the country’s sustainable transport and carbon neutrality goals.
Exponent Energy’s P4 charger is poised to revolutionize the rapid charging infrastructure landscape, offering an affordable, scalable, and future-ready solution that aligns perfectly with India’s vision for clean and efficient electric mobility.
