The invention discloses a system for protecting batteries of an electric automobile and relates to the automobile including energy storage devices. The automobile including the energy storage devices comprises the multiple energy storage devices, a motor, in-automobile electronic equipment, a plurality of convertors, a switch and a controller. The multiple energy storage devices supply electricity to the motor and the in-automobile electronic equipment through the multiple convertors, and the controller responds to the detected failure condition so as to enable the multiple energy storage devices to discharge the electricity or transfer energy. When an accident is detected, energy in the batteries can be rapidly reduced; energy in a battery set is reduced through a rapid cooling system; and the energy in the batteries can be rapidly transferred to each singular high-capacity energy storage device, and the singular energy storage device is cooled, so that the situation that heat generated by a certain damaged battery is transmitted to the other batteries, consequently, the adjoining batteries conduct the same exothermic reaction, and linkage hazardous reactions are spread is prevented.
