The invention relates to the technical field of electric vehicles, and particularly relates to a vehicle-mounted battery safety detection system applied to an electric vehicle. The vehicle-mounted battery safety detection system comprises a vehicle-mounted battery, a signal acquisition and conversion circuit, a single-chip microcomputer, a level conversion chip, an RS-232 serial communication interface and an upper computer which are connected in turn. The single-chip microcomputer is connected with a temperature sensor. Temperature of the vehicle-mounted battery is detected in real time so that monitoring of temperature of the vehicle-mounted battery can be ensured and safety of temperature of the vehicle-mounted battery can be guaranteed; meanwhile, voltage and current information fed back by the vehicle-mounted battery is collected and converted by using the signal acquisition and conversion circuit so as to prevent the risk of work caused by abnormality of voltage and current; besides, viewing of data inf
