BatteryOK Technologies founded EV Doctor in 2019, when founder Shubham Mishra was working at Gensol (parent company of BluSmart cabs), he noticed the lack of reliable battery diagnostic in the EV sector.
Shubham noticed that unsafe methods, like directly touching the hot batteries with bare hands (for checking battery health), are still in practice.
This practice clearly highlights a critical gap in safety and accuracy.
Early Days
Before launching EV Doctor, the team launched E-Vega Mobility Labs to bring affordable e-bike components.
With a great concept, they successfully received early grants, including ₹2 lakh from Gujarat University Startup and Entrepreneurship Council (SSIP) and ₹5 lakh from NIDHI-PRAYAS.
However, the COVID-19 pandemic forced a strategic pivot from hardware manufacturing to battery diagnostics technology.
Product Development: EV Doctor by Shubham Mishra and Ajay Vashisht
Under the guidance of mentors like Dr. Judith Jeevarajan (ex-NASA battery safety head) and Sameer Jindal (MG Motor India), the team (Shubham Mishra and Ajay Vashisht) successfully developed EV Doctor, an AI-powered, portable device.
Purpose: It provides accurate and rapid diagnostics for lithium-ion batteries. It addresses safety, longevity, and performance concerns related to EVs.
Struggles and Challenges
Pandemic Disruption: The COVID-19 pandemic halted their initial e-bike venture and forced a reevaluation of their business model. The team used this period to deeply research battery safety and diagnostics, connecting with industry experts and battery manufacturers online.
Technical Hurdles: Developing a universally compatible diagnostic device was challenging. Early prototypes were built using basic components like phone boxes and Arduino boards. Incorporating diverse feedback from dealers and workshops led to complex feature requests, making the product initially cumbersome. The team had to balance versatility with practicality, iterating constantly to refine the device.
Market Fit and Awareness: Convincing EV workshops and battery dealers to adopt a new technology required persistent outreach. Many were accustomed to traditional, manual methods and skeptical of digital diagnostics. The team invested heavily in demos, pilots, and user education.
Bootstrapping: BatteryOK Technologies remained bootstrapped, relying on founder savings and reinvested revenues. Shubham initially used his master’s stipend (earned via GATE) to fund the company, reinforcing a philosophy of validating the product through customer revenue rather than investor capital.
Product Adoption
As of 2025, over 1,500 units of EV Doctor have been deployed, with around 1,000 customers globally. Clients span India, Korea, Mauritius, Mexico, and Europe, reflecting strong international traction.
Growing the Team
The company has grown to a 22-member team, with deep expertise in technology, marketing, and operations. This diverse talent pool has driven rapid product development and market expansion.
Revenue and Business Model
While specific annual revenue figures are not publicly disclosed, the company is fully bootstrapped and profitable, with all growth funded by sales revenue. The founders emphasize that customer payments, not investor funding, have sustained and validated their business.
Gaining Recognition and Making Industry Impact
EV Doctor is recognized as a game-changer in the EV ecosystem, helping workshops and dealers quickly, safely, and accurately diagnose battery health. The device’s AI-driven insights are credited with improving battery safety and performance, reducing risks like thermal runaway, and setting new standards for battery diagnostics.
Future Vision
The team is now working on a universal operating system for batteries under “Energy AI Labs,” aiming to provide continuous diagnostics and predictive insights for batteries across applications-from scooters to grid-scale storage.
Do You Know?
The name “EV Doctor” was inspired by a mechanic at an expo who likened the device to a doctor for batteries, prompting a rebranding from the original “rapid testing machine”. The company has since secured trademarks and patents for the name. The founders actively share updates on LinkedIn about product deployments, industry partnerships, and their mission to make every garage in India EV-ready. The startup is frequently highlighted in sustainability and innovation forums for its impact on EV safety and maintenance.
EV Doctor’s journey is a testament to resilience, technical innovation, and market-driven growth. By addressing a critical gap in EV battery diagnostics, the startup has established itself as a trusted partner for the global EV ecosystem, with a bootstrapped, revenue-driven model and a clear vision for the future.
