Is the emergency calling function related to the small battery? Is there a backup battery that allows the emergency calling function to connect?
Official answer
The Automatic Emergency Calling System (E-CALL) of the Xiaomi SU7 is equipped with a backup battery, which can maintain communication for a period of time even if the main power supply is disconnected;
Additionally, even if a severe collision causes damage to the vehicle's infotainment system, the Automatic Emergency Calling System (E-CALL) of the Xiaomi SU7 can still operate through an independent microphone/speaker;
These two redundant designs can maximize the ability to maintain emergency calling functionality, thereby improving rescue efficiency.
