Electric vehicle battery abnormality warning system and device

Abstract

An electric vehicle battery abnormality warning system and device are disclosed, applicable to an electric vehicle. The electric vehicle battery abnormality warning device includes at least one sensing unit and one receiving unit. The at least one sensing unit is detachably mounted on the underside of the electric vehicle and includes a sensing module, a wireless communication module, and a sensing control module. The sensing module outputs a temperature signal, the sensing control module receives the temperature signal, and the wireless communication module outputs a fire alarm signal. Because the sensing unit is located on the underside of the electric vehicle, when the electric vehicle battery overheats abnormally or accidentally catches fire, the receiving unit can output a fire alarm warning signal to the vehicle owner, allowing the owner to immediately be aware of the abnormal battery temperature and take appropriate measures such as fire extinguishing, ensuring excellent safety.
