The EV Doctor ensures that every electric vehicle meets critical safety and performance standards through a comprehensive health assessment. In just 15 minutes, the diagnostic process delivers a detailed evaluation of the vehicle’s condition, with a particular focus on battery health. This comes at a time when India is seeking to attain a 30 percent share of electric vehicles in the total vehicles sold by 2030, according to a NITI Aayog report titled ‘Unlocking a $200 Billion Opportunity: Electric Vehicles in India’. 

A total of 23,865 accidents involving electric vehicles were recorded across various states over the last three years. Of these, 26 incidents involved fires. When it comes to EVs, battery health is of paramount importance, and any slip is a logistical nightmare with far-reaching repercussions. 

Now, a model solution by the Gujarat-based startup BatteryOk Technologies may have the solution.  

Focused on improving the safety, reliability, and efficiency of electric vehicle (EV) batteries through advanced diagnostics and AI (artificial intelligence), engineers Shubham Mishra and Ajay Vashisht decided to curate a ‘doctor’ to diagnose faulty batteries, assess the complications in their health, all this without the use of imported machinery. 

The EV Doctor vs traditional systems  

What appears to be a 300-gram frame that can pinpoint the problems in an EV battery is the result of years of research, fine-tuned artificial intelligence tools and the expertise of multiple battery manufacturers and service technicians. 

The root of the problem lay in existing methods and their reliance on bulky charge-discharge systems that required several hours to generate basic battery performance data, limiting their practicality for routine use.

EV Doctor, on the other hand, is an AI-powered battery diagnostic device capable of assessing battery health, safety, performance, and potential faults within approximately 15 minutes. The portable device uses real-time battery data and multiple machine-learning models to generate detailed diagnostic reports without requiring batteries to be dismantled. 

It is designed to work across a wide range of battery types and configurations. The solution offers a faster, safer, and more cost-effective alternative to traditional testing methods.

Since its launch in 2022, EV Doctor has gained significant adoption across the EV industry. The device is currently used in more than 1,700 workshops and service centres across India and several international markets, including South Korea, Vietnam, Mexico, Mauritius, and the United States. BatteryOk’s clientele includes leading mobility and energy companies such as MG Motor, Zypp Electric, Yulu, JioBP, and Jitendra EV.

The technology behind diagnostics 

The first step is assessing how an EV battery behaves when electricity flows through it.

That’s what the EV doctor does. 

Then it combines the power of 25 AI models to understand the overall health of the battery, the safety, performance and faults. 

The device collects real-time data such as voltage, current, and charging behaviour, which is transmitted to cloud-based analytical systems to evaluate battery condition, identify faults, measure capacity degradation, and detect potential safety risks. The system then generates a detailed diagnostic report that can be accessed through a mobile application.

Designed to be compact and portable, the 300-gram device is compatible with a wide range of battery types, including those with and without Controller Area Network (CAN) communication systems. It can test batteries up to 100 volts and 100 ampere-hours, making it suitable for various electric mobility applications, with the company claiming an accuracy rate of more than 96 percent. 

Through the combination of artificial intelligence, cloud computing, and battery analytics, EV Doctor provides a scalable solution for battery diagnostics and lifecycle management.

Scaling with India’s electric mobility revolution

The sale of EVs in India went up from 50,000 in 2016 to 2.08 million in 2024. The country is on its way to becoming a boomtown in terms of EV acceptance.

But with more people jumping on the EV bandwagon, there is a rising concern to ensure that battery health is in perfect shape. 

As EV fleets expand across public transport, delivery services, ride-hailing platforms, and personal mobility, reducing battery-related incidents becomes essential for safer cities.

One of the most crucial focuses is the issue of batteries catching fire. The EV Doctor provides risk prediction of thermal runaway (a phenomenon where a battery overheats). 

These predictive algorithms can identify potential fire hazards before they occur.  

Emphasising that R&D for new battery technologies should be better suited to the Indian context, the NITI Aayog report implies that only when safer battery diagnostic technologies are made available to Indian citizens will it compound the speed of adoption of EVs, resuscitating people’s belief in cleaner technologies and supporting cleaner urban transportation.

This, in turn, will reduce cities’ dependence on petrol and diesel vehicles, improving air quality and public health. 

When we turn our gaze towards the larger picture, battery diagnostics can identify whether a battery truly needs replacement or can continue operating safely. Extending battery life by even a few years reduces battery disposal rates and lowers demand for new battery production, supporting a more sustainable urban economy. 

To this end, BatteryOk’s EV Doctor is not merely a diagnostic tool. By improving safety, extending battery lifespan, reducing waste, lowering costs, and increasing trust in electric vehicles, it’s helping cities move towards a future that is cleaner, more efficient, and more sustainable.
