Abstract

The invention discloses a power monitoring and energy saving system which comprises a discharging circuit module and a grid-connected inverting circuit module, wherein the grid-connected inverting circuit module comprises a high-performance DSP (Digital Signal Processing) main board; the input end of the discharging circuit module is connected into the input end of the grid-connected inverting circuit module, and the output end of the grid-connected inverting circuit module is connected into a power grid; the discharging circuit module comprises an LC filtering circuit consisting an inductor L1 and a capacitor C1 and a power pipe Q1; and the power pipe Q1 and an inverting circuit are both controlled by the high-performance DSP main board. The LC filtering circuit is adopted in the discharging module and can obtain constant current and voltage; and when in use, the system can run in a constant current, resistance and power state just by setting the power supply ageing condition of the system and the current, resistance and power of a storage battery in a charging and discharging test, calculating and analyzing a set parameter by the high-performance DSP main board and outputting a corresponding parameter value for controlling conduction or interruption of the power pipe.

Description

technical field

[0001] The invention relates to a power supply product aging and charging and discharging testing system for storage battery products, in particular to an electric energy monitoring and energy saving system for charging and discharging testing of chargers, adapters, switching power supplies and storage battery products. Background technique

[0002] Before leaving the factory, electronic products such as power supplies usually need to be aged for a certain period of time in order to stabilize their performance. This can eliminate early failure products, which is an important means of quality control of power supplies.

[0003] Power aging is to make power products work under a certain temperature, input voltage, and load current environment. The aging of power supply products in industries such as chargers, adapters, and switching power supplies is carried out by traditional resistance load simulation. This aging method is relatively simple in principle: whe...
