Engineers Build 15-Minute EV Battery Test Now in 1,500 Shops

In summer 2020, Shubham Mishra watched a technician test a burning-hot electric bike battery with his bare hands. No tools, no protection, just dangerous guesswork.

That moment changed everything. Shubham, who'd been working at Gensol Engineering, had already been dreaming about making electric vehicles more accessible. Seeing that technician risk his safety to perform basic maintenance pushed him over the edge.

He quit his job and teamed up with Ajay Vashisht, an instrumentation engineer who shared his vision. Together, they launched E-Vega Mobility Labs in 2019 with just Rs 2 lakh in grant funding and Rs 5 lakh from NIDHI-PRAYAS.

Then the pandemic hit. Instead of giving up, they spent lockdown talking to battery makers and EV experts. The message came through loud and clear: batteries were misunderstood, and testing methods were stuck in the past.

"Existing methods were slow, clunky, and offered very little insight," Ajay explains. "I believed we could compress hours of testing into minutes."

In 2021, they launched BatteryOk Technologies. By August 2022, they unveiled EV Doctor, a 300-gram device powered by more than 25 AI models that delivers a complete battery health report in just 15 minutes through a mobile app. The accuracy? Over 96.7 percent.

The results speak volumes. Pawan, a workshop owner in Udaipur, used to test maybe two or three batteries daily. Now he handles 10 to 15. "It's like a full body check-up, but for batteries," he says. "I've tested hundreds, and not a single one has led to thermal issues."

The Ripple Effect

The growth started slow. Twenty units sold in year one. Then 150 in 2023, and 500 in 2024. By the end of 2025, over 1,500 devices will be diagnosing batteries in workshops across the globe.

The team slashed the price from Rs 25,000 to Rs 10,000 for smaller garages, making safety accessible to everyone. Their testing doesn't just prevent fires. It extends battery life by eight to 10 years, keeping EVs on the road longer and reducing waste.

From one technician's risky bare-handed test to 1,500 workshops equipped with precision tools, these engineers built more than a device. They built trust in an industry that desperately needed it.
