Embodiments of the present invention provide a power supply apparatus and method, and a user equipment. The apparatus includes: a battery electric core, a switch device, a voltage boost circuit, a state detection circuit, and a logic control circuit. The switch device is connected in a current path of the battery electric core. The voltage boost circuit is connected in parallel to the current path, and is configured to boost an output voltage of the battery electric core. The state detection circuit is configured to detect a state of the battery electric core and a state of the apparatus, and generate a state signal. The logic control circuit is configured to receive the state signal from the state detection circuit, and control the switch device according to the state signal, when the battery electric core is in an abnormal charging state, control the switch device to turn off the current path, and when the voltage boost circuit is not required to work, control the switch device to turn on the current path. In the embodiments of the present invention, charging protection for the battery electric core and a bypass function for the voltage boost circuit can be implemented through control that is performed on the switch device by the logic control circuit, so that additional impedance can be reduced and working efficiency can be improved. |
