The invention belongs to the technical field of battery sharing, and particularly relates to a battery replacing cabinet system, which comprises a mainboard, an external antenna, an electric meter, anexternal temperature sensor, a loudspeaker, a heating plate, a fan, an RS485 bus and a plurality of lock control plates, wherein the external antenna, the electric meter, the external temperature sensor, the loudspeaker, the heating plate, the fan and the RS485 bus are connected to the mainboard, and the lock control plates are connected to the RS485 bus. According to the invention, the temperature and the humidity in the battery cabinet and the temperature outside the cabinet can be detected, and the operating temperature and the operating humidity in the battery cabinet can be dynamically adjusted according to the detection results, such that the proper temperature and the proper humidity in the battery cabinet can be ensured so as to easily prolong the service life of each element; theproper charging voltage and the proper charging current can be automatically matched according to the type of the battery, such that the applicability is strong; and the charging current of the battery can be intelligently set at the battery replacement peak and the battery replacement valley so as to shorten the charging time and save the energy.
