Abstract

Embodiments of this application provide a power supply circuit and a related apparatus, used in the field of terminal technologies. The power supply circuit includes: an EIS module connected to a battery, a controller, and a power management module. The EIS module is connected to the controller, and the controller is connected to the power management module. The EIS module may detect an internal resistance of the battery and transmit the internal resistance of the battery to the controller. The controller may obtain a charge cutoff voltage and/or a charge cutoff current of the battery according to the internal resistance of the battery, and send a first control signal to the power management module. The power management module may control the charge cutoff voltage and/or the charge cutoff current of the battery according to the first control signal. In this way, a charging policy of the battery is adjusted by using the internal resistance of the battery that is detected by the EIS module. Based on the internal resistance of the battery, an aging degree of the battery is represented and adjusted, to reduce a case in which the charging policy does not match the aging degree of the battery, so as to reduce phenomena such as heat generation, bulging, and insufficient charging of the battery, and improve safety of the battery.
