A smartphone application designed to monitor lithium-ion batteries has sparked concern after viral videos showed pranksters allegedly switching off electric three-wheelers while they were on the move.
The app, known as BAT-BMS, is intended to connect with Bluetooth-enabled battery management systems (BMS) to monitor battery health, charge levels and performance. However, videos circulating on social media claim that it can also be used to remotely switch off certain battery-powered vehicles, prompting fresh debate over the cybersecurity of electric mobility.
How the app works
According to reports, the BAT-BMS app wirelessly connects to compatible lithium battery systems using Bluetooth, allowing users to monitor battery parameters such as voltage, temperature and charging status. Some battery management systems also provide administrative controls, including the ability to disable battery output.
Experts note that the app does not work on every electric vehicle. It is limited to vehicles fitted with compatible Bluetooth-enabled battery management systems and only functions within Bluetooth range, typically around 10 to 15 metres.
Security concerns emerge
The viral prank videos have raised questions about whether adequate security measures exist to prevent unauthorised access to connected battery systems. Industry observers say the incident highlights the need for stronger authentication, password protection and secure Bluetooth pairing in electric vehicle battery management systems.
There is currently no official confirmation that all electric three-wheelers or other EVs are vulnerable to such misuse. The issue appears to affect only specific vehicles equipped with compatible smart battery systems.
The incident has reignited discussions on the importance of cybersecurity as India’s electric vehicle ecosystem expands, with experts urging manufacturers to strengthen digital safeguards alongside vehicle safety.
