The invention relates to the field of technologies for controlling photovoltaic solar energy to charge batteries, and in particular relates to a photovoltaic solar charging control device with zero loss and a realization method thereof. The device comprises a solar panel, a diode, a transistor, a battery and two mechanical relays A and B. In the device, two ends of the diode for preventing back discharge are connected with the controlled mechanical relay A in parallel, so that a charge current can flow through a contact of the mechanical relay A directly rather than flowing through the diode in a return circuit when the system works, thus the diode is not subjected to tube voltage drop loss. For the purpose of improving the reliability of the solar charging system, a charging voltage is controlled by parallel combination of the controlled mechanical relay B and the transistor rather than a working control mode of a switching power supply, thus the system can not only capture an opportunity that normal sunlight is utilized to charge the battery but also eliminate reactive loss caused by controlling devices of the transistor in the return circuit, thereby reaching the zero loss control effect.
