Abstract

The present invention discloses a power supply circuit, comprising a power supply module, a chargeable battery, a system power supply, a step-down circuit, a super capacitor and a booster circuit. The power supply module is connected to the super capacitor via the step-down circuit and is charged. The super capacitor is boosted through the booster circuit and then supplies power to the outside via a system circuit. The present invention also discloses a power supply method of the power supply circuit, comprising a charging step and a discharging step. The present invention also provides a power-consumption information acquisition terminal which is manufactured by the power supply circuit and supplies power by the power supply method. By the invention, the data reliability of a power-consuming load is ensured, and long service lifetime, high reliability, simple circuit and wide application range are achieved.

Description

technical field [0001] The invention specifically relates to a power supply circuit, a power supply method and a power consumption information collection terminal made thereof. Background technique [0002] With the development of the country's economy and technology and the improvement of people's living standards, people have begun to pay more and more attention to the reliability of electrical equipment. The reliability of power grid equipment during power outages and instantaneous power failures has also become one of the reliability indicators for evaluating power grid equipment. [0003] At present, most of the core components that support grid equipment to continue to work after grid power failure or power failure are still rechargeable batteries (the circuit module diagram of which is shown in figure 1 shown): After the external power supply enters the power circuit, the signal conversion is performed through the power module, and then the power output is provided e...
