Problems solved by technology

The energy in the supercapacitor is stored on the electrode and the surface of the electrolyte in the form of static charge, and the charging and discharging process is almost a physical process. Therefore, overcharging and overdischarging have little impact on the life of the supercapacitor, and there is no memory effect
Compared with batteries, supercapacitors have extremely high cycle life (usually greater than 500,000 times) and power density, but their energy density is very low (10-30Wh / L)
[0005] Aiming at the problem that important things such as computer files and projects are suddenly damaged in the case of a sudden power failure or power disconnection of the existing desktop computer, the currently used battery-based capacitive battery UPS power supply is expensive and is generally used in important security units. Such as radio stations, factories, etc.
And battery-based UPS overcharge and overdischarge both lead to short battery life

Abstract

The invention discloses an instantaneous power-off prevention system based on a capacitor battery and a working method thereof. A controller input end is connected with a voltage detection module, a controller output end is connected with a relay, a controller is further connected with a grid monitoring terminal through a wireless communication module, the voltage detection module is connected with the external power grid, a relay output end is connected with a backup power supply, and the external power grid, the backup power supply and a capacitor battery UPS power supply are all connected with a load device. The working method includes steps that the required capacitance is calculated according to the power of most existing computers; the UPS uninterruptible power supply is made according to the capacitance; the uninterruptible power supply is connected with a computer, the UPS uninterruptible power supply is charged till the power is sufficient; whether a desktop computer is powered off is determined, if yes, the UPS uninterruptible power supply is started. The system is advantaged in that the system is safe and reliable, has high accuracy and has strong practicality.

Description

Technical field: [0001] The invention relates to the technical field of capacitor battery UPS power supply, in particular to a capacitor battery-based instantaneous power failure prevention system and a working method thereof. Background technique: [0002] With the rapid development of society's informatization and modernization process, and the gradual improvement of people's living standards, users have higher and higher requirements for power supply reliability. Important event places such as government agencies, gymnasiums, large hospitals, and large conference centers, etc., in the event of a power outage, the consequences are unimaginable, which will not only disrupt normal production and living arrangements, but also cause certain economic losses and serious negative social influence. Therefore, uninterruptible power supply technology needs to be studied to maintain a normal and stable social life order. [0003] At present, information is exploding at a high speed...
