The invention discloses an uplink carrier aggregation control method and device and terminal equipment. The method comprises the following steps: monitoring battery real-time data corresponding to preset battery parameters through a baseband chip when a radio-frequency transceiver of the terminal equipment performs information transmission in an N-path uplink carrier aggregation way, wherein N is an integer being greater than 1; and controlling the radio-frequency transceiver to reduce M paths of uplink carriers through the baseband chip if the battery real-time data do not satisfy preset index data, wherein M is smaller than N, and greater than or equal to 1 in order that the battery real-time data of the battery parameters corresponding to the rest of (N-M) paths of uplink carriers satisfy the preset index data. According to the method, the battery real-time data corresponding to the battery parameters of the terminal equipment are monitored, and the number of paths of the uplink carriers is reduced when the battery real-time data do not satisfy the preset index data, so that power consumption of the terminal equipment is controlled reasonably, and the user experience is balanced on the premise of ensuring the cruising ability of the terminal equipment.
