The drivers seem confused whereas the folks filming giggle. On the streets, although, this social media ‘development’ has created an actual hazard.
Behind the jokes is a fundamental flaw in how some electrical three-wheelers are constructed. Many trendy e-rickshaws use Bluetooth-enabled battery programs. To watch battery well being, producers use apps like BAT-BMS and Lossigy.
A few of these programs have been constructed with none password safety or authentication. Anybody inside Bluetooth vary can obtain the app, connect with a close-by car, and reduce its energy with one faucet.
In a check carried out by Hindustan Instances with a driver’s consent, an e-rickshaw was switched off remotely and will solely be restarted by way of the identical app.

The issue will not be within the app itself however the way in which some battery programs are constructed.
Many low-cost lithium-ion battery packs utilized in e-rickshaws include Bluetooth turned on and no password safety. This enables anybody close by to connect with the battery utilizing apps reminiscent of BAT-BMS or Lossigy.
After connecting, a person can faucet the “Discharge Change” contained in the app.
