The invention provides a voltage transmission control circuit which comprises a positive transmission line of the voltage and a negative transmission line of the voltage, wherein one end of the positive transmission line of the voltage is connected to a positive electrode of a battery, the other end of the positive transmission line of the voltage is connected to a positive transmission port of the voltage, and a first contactor is connected in series between the positive electrode of the battery and the positive transmission port of the voltage; one end of the negative transmission line of the voltage is connected to the negative electrode of the battery, the other end of the negative transmission line of the voltage is connected to a negative transmission port of the voltage, and a first breaker and a second contactor are connected in series between the negative electrode of the battery and the negative transmission port of the voltage; and when the current on the positive transmission line of the voltage is not less than the adhesion current, the first breaker is disconnected. By implementing the voltage transmission control circuit, the connection between the negative electrode of the battery and the negative transmission port of the voltage is effectively disconnected, and the use safety of the voltage transmission control circuit is improved.
