A viral social media trend in India has brought the Chinese app BAT-BMS into the spotlight. Videos circulating on Instagram, YouTube, Reddit, and X show users connecting to nearby e-rickshaws through Bluetooth and remotely disabling their batteries, leaving drivers stranded and confused. The trend, popularly referred to as “Tirri Control”, has raised serious concerns about electric vehicle cybersecurity and the misuse of connected technology.
What Is BAT-BMS?
BAT-BMS is a legitimate Battery Management System (BMS) application developed to monitor and control compatible Bluetooth-enabled lithium batteries. The app allows users to check battery voltage, temperature, charging status, current, and battery health. On supported batteries, it can also control charging and discharging functions remotely.
How Does the Prank Work?
Many low-cost lithium battery packs used in some Indian e-rickshaws reportedly feature Bluetooth-enabled battery management systems with little or no password protection. When someone comes within Bluetooth range—typically around 10 to 15 metres—they may be able to connect to the battery and switch off its power output. This causes the vehicle to stop until the battery is turned back on.
Why Is It Going Viral?
Creators have been uploading videos showing themselves stopping random e-rickshaws as a prank, often recording the confused reactions of drivers. While some social media users have treated the videos as entertainment, many others have criticised the trend for targeting drivers who rely on their vehicles to earn a daily income. Reports even mention cases where stranded drivers paid strangers to help restart their vehicles.
Does It Affect Every Electric Vehicle?
No. The issue is believed to affect only certain vehicles using compatible Bluetooth-enabled battery management systems without proper security measures. Most modern electric cars and premium electric two-wheelers use stronger authentication and encrypted communication, making unauthorized access much more difficult.
Growing Cybersecurity Concerns
The incident has highlighted an important challenge for India’s rapidly expanding electric vehicle market. As EVs become more connected through wireless technologies, manufacturers are expected to strengthen security by implementing password protection, encrypted Bluetooth communication, and secure authentication to prevent unauthorized access to battery systems.
Looking Ahead
Although BAT-BMS itself is a legitimate battery management tool, its alleged misuse has exposed security weaknesses in some battery systems used by low-cost electric vehicles. The viral trend serves as a reminder that cybersecurity is becoming just as important as mechanical safety in the future of connected mobility. Experts believe stronger software protections and better security standards will be essential as India’s EV ecosystem continues to grow.
