Description

technical field

[0001] The present application relates to the field of electronic equipment, and more specifically, to a terminal equipment and a method for controlling a conversion circuit. Background technique

[0002] In order to increase the total voltage of the battery components of the terminal equipment, the battery components of the terminal equipment generally adopt a battery series structure. For a battery assembly in which multiple batteries are connected in series, a conversion circuit is required to convert the voltage provided by the battery assembly into the input voltage of the system load in the terminal device.

[0003] However, the current conversion circuit has a problem that the voltage conversion efficiency is low or the available battery remaining capacity of the battery module is greatly reduced at low temperature, which leads to the shutdown of the terminal device. Contents of the invention

[0004] The present application provides a terminal devi...
