From Petrol Pump to Power Station in One Day
Here’s where Exponent Energy gets brilliant. The company isn’t asking drivers to buy new electric autorickshaws—they’re converting existing ones. Every ICE component gets removed, clearing space and reducing weight. Then comes the magic: Exponent’s proprietary electric powertrain slides right in.
“The entire retrofit can be completed within 24 hours,” says Ayush Bhargava, head of business at Exponent Energy. That’s faster than most people get their smartphones repaired.
The 15-Minute Charging Revolution
Forget waiting hours at charging stations. Exponent’s secret weapon is its in-house developed battery technology that charges from empty to full in just 15 minutes. How? It’s all about their integrated ecosystem:
The E-Trio System:
- E-Pack: The battery pack itself
- E-Pump: Specialized charging stations
- E-Plug: Proprietary charging connector

These three components work together seamlessly, engineered specifically to deliver rapid charging without compromising battery life. Unlike conventional EV batteries that degrade quickly with fast charging, Exponent’s system warranties 3,000 charging cycles even with daily rapid charging.
Why Drivers Are Making the Switch
Let’s talk money—because that’s what really matters to autorickshaw drivers hustling through city traffic daily.
Monthly Cost Breakdown: Current LPG/CNG prices in urban centers are crushing operational budgets. By switching to Exponent Oto, drivers can pocket up to ₹5,000 extra each month. That’s ₹60,000 annually—enough to transform a family’s financial trajectory.
Extended Vehicle Life: The conversion doesn’t just save money; it extends the vehicle’s usable life. That aging autorickshaw you thought was ready for the scrapyard? It gets a second lease on life as a modern electric vehicle.
Zero-Risk Financial Model
Exponent Energy understands that ₹1.7 lakh sounds steep for drivers operating on tight margins. That’s why they’ve engineered the financial side as carefully as the technical:
✅ Zero down payment – Start saving immediately ✅ Flexible EMI options – Pay as you earn ✅ Assured buyback after 3 years – Exit strategy built-in
It’s not just a retrofit; it’s a complete financial ecosystem designed for drivers, by people who understand their reality.
The Bigger Vision: 2.5 Million Conversions
Exponent Energy isn’t thinking small. Out of India’s estimated 8-10 million autorickshaws, they’re targeting 2-2.5 million conversions across the top 20 cities. The company is rapidly scaling from a few hundred conversions monthly to several thousand.
Why the confidence? Real-world results. Since founding in 2020 by former Ather Chief Product Officer Arun Vinayak, Exponent has already:
- Deployed technology in 2,100 EVs
- Established 150 charging stations
- Completed over 1 million rapid charging sessions
- Raised $44.6 million from top-tier investors including Lightspeed and Hero MotoCorp’s family office
Where You Can Find Them
Currently operational across Delhi-NCR, Bengaluru, Chennai, and Ahmedabad, Exponent Energy is rapidly expanding its footprint. The charging infrastructure grows alongside conversion capacity, ensuring no driver gets left stranded.
The Environmental Win Nobody’s Talking About
While everyone focuses on costs and convenience, here’s the silent revolution: Each converted autorickshaw removes one polluting ICE vehicle from congested city streets. Multiply that by 2.5 million, and you’re looking at a massive reduction in urban air pollution.
With zero tailpipe emissions and energy-efficient charging, these retrofitted vehicles become part of India’s clean mobility future—without waiting for drivers to afford brand-new electric autorickshaws.
What This Means for India’s Streets
Exponent Energy‘s EV retrofit technology represents more than just a business opportunity—it’s a pragmatic solution to India’s urban mobility and pollution challenges. By making electric conversion accessible, affordable, and genuinely beneficial for drivers, they’ve cracked the code that’s stumped many EV startups.
The 24-hour conversion promise, 15-minute charging capability, and driver-first financial model could finally trigger the mass EV adoption India desperately needs. And it’s happening one autorickshaw at a time, proving that revolutionary change doesn’t always require revolutionary vehicles—sometimes it just requires revolutionary thinking.
