The invention discloses a safety control system of an electric vehicle battery pack. The safety control system comprises multiple controllable switches, a battery management system and a whole vehicle controller, wherein each controllable switch is serially connected between adjacent two simple batteries; the battery management system is respectively connected with each simple battery of the battery pack, acquires the voltage and the temperature of the simple batteries and the current of the battery pack, and sends to the whole vehicle controller; and the whole vehicle controller is respectively connected with each controllable switch, and controls the connection/disconnection of the corresponding controllable switches according to the voltage, temperature and current information sent by the battery management system. The safety control system adopts the battery management system BMS to acquire the current, the voltage and the temperature of the battery pack in real time, adopts an insulation monitor to detects insulation faults of the battery pack in real time, and uses the whole vehicle controller for controlling the disconnection of the controllable switches among the batteries according to detecting results, so that the risk of battery spontaneous combustion or person electric shock is effectively prevented and warned, and the protection for whole vehicle parts and personal and property safety is realized.
