The invention relates to a voltage type super capacitor detection circuit. Firstly, the overall voltage of a super capacitor is measured via a controlled voltage division circuit; the voltage of the middle point of each super capacitor bank, namely the voltage of the lower half part of the super capacitor bank, is measured via a controlled voltage division circuit connected with the middle point of the super capacitor bank; the voltage of the upper half part of each super capacitor bank can be acquired by subtracting the voltage of the lower half part from the overall voltage. If the difference between the voltage of the upper half part and the voltage of the lower half part is great, the super capacitor bank is subjected to a fault.
