The invention relates to a waterproof rolling handle control circuit for an electric vehicle. The waterproof rolling handle control circuit comprises a Hall element, wherein the signal output end of the Hall element is connected with collector electrodes of a first switching transistor and a second switching transistor respectively, the base electrode of the first switching transistor is controlled by an MCU module, and the emitter electrode of the first switching transistor is connected with a first signal input end of the MCU module; the base electrode of the second switching transistor is controlled by the MCU module, and the emitter electrode of the second switching transistor is connected with a series-connected voltage division circuit, the output end of the series-connected voltage division circuit is connected with a voltage follower, and the output end of the voltage follower is connected with a second signal input end of the MCU module. The waterproof rolling handle control circuit disclosed by the invention is simple. Through simple series-connected voltage division, when the output voltage of the Hall element is reduced, the voltage reduction manner is liner because of the characteristic of resistance; and the voltage follower is arranged to realize the function of isolation so that a sampling voltage is stabilized. The waterproof rolling handle control circuit disclosed by the invention has the characteristics of simple structure, low cost and good reliability.
