Abstract: A power supply circuit and system. The power supply circuit comprises: a temperature detection module (11); a voltage regulation control module (12); a voltage regulation module (13); and a battery module (14). The temperature detection module is used to detect an ambient temperature, and to transmit the detected ambient temperature to the voltage regulation control module. The voltage regulation control module is used to determine whether the ambient temperature is lower than a set temperature threshold. If the ambient temperature is lower than the set temperature threshold, the voltage regulation control module transmits an activation instruction to the voltage regulation module. The voltage regulation module is used to adjust, in response to the activation instruction, an output voltage of the battery module to a target voltage, and to output the target voltage. The target voltage is a voltage meeting an operating requirement of a terminal device. The above method enables a power supply voltage to be regulated to a voltage meeting operating requirements of a terminal device in low temperature environments, thereby ensuring normal operation of the terminal device in low temperature environments.
