Storage battery power supply detection system for electric vehicle

The utility model discloses a storage battery power supply detection system for an electric vehicle, and the system comprises a voltage detection module which detects the voltage outputted by a charger through a triode Q1, and carries out the switching of a conduction path according to a relay T1; the voltage regulating module receives the break-over voltage of the normally closed contact S1, reduces the break-over voltage through a resistor TR2, and transmits the break-over voltage to the voltage stabilizing module; the voltage stabilizing module receives the break-over voltage of the normally open contact S2, stabilizes the break-over voltage through a voltage stabilizer U1, and transmits the break-over voltage to the current stabilizing module; the current stabilizing module processes the current in the path through an inductor L1 and safely outputs the current to a storage battery; according to the utility model, the voltage output by the charger is detected through the resistor R3 and the triode Q1, path
