Battery OK Technologies

Battery OK Technologies is an Ahmedabad-based clean-tech and electric mobility technology company focused on solving one of the most critical challenges in the EV ecosystem: battery diagnostics, safety, servicing and repair.

The company operates under E-Vega Mobility Labs LLP, which was founded in 2019, and has developed EV DOCTOR™, an AI-powered battery diagnostic technology designed to assess the health, safety, performance and faults of electric vehicle batteries.

Rather than relying on conventional testing methods, EV DOCTOR™ combines battery measurements, diagnostic protocols, machine-learning models and digital reporting to provide service professionals with actionable information about an EV battery.

The company's technology is positioned for EV workshops, manufacturers, dealerships, fleets, financiers, insurers, battery businesses and other participants in the EV ecosystem.

The EV battery is one of the most important and expensive components of an electric vehicle, but the aftermarket historically lacked a fast, standardised and independent way to determine its actual condition.

A vehicle may look perfectly healthy while its battery has:

Reduced capacity
Cell imbalance
Internal resistance issues
Thermal problems
Charging abnormalities
Water damage
Degradation
BMS-related faults
Other safety risks

This creates uncertainty for almost every participant in the EV lifecycle.

Battery OK's business model is primarily B2B technology-led, combining hardware, diagnostics, enterprise applications and ecosystem partnerships.

Its current product offering includes different EV DOCTOR™ configurations targeted at different customer groups.
