Direct-current emergency power supply device with supercapacitor module

Abstract

A direct-current emergency power supply device with a supercapacitor module comprises a human-machine interface, a capacitor charging unit and an alternating-current monitoring unit used for collecting voltage of an alternating-current power source; both the capacitor charging unit and the alternating-current monitoring unit are connected with the alternating-current power source; the output end of the capacitor charging unit is connected with a capacitor module; the capacitor module is connected with direct-current output; the output end of the direct-current output is an output end of the emergency power supply device; the output end of the direct-current output is further connected with a direct-current detecting unit used for collecting voltage, charging current and discharging current of the capacitor module; the direct-current detecting unit and the alternating-current monitoring unit are both connected with the human-machine interface. The direct-current emergency power supply device has the advantages of simple structure, portability, good low temperature performance, intelligence of displaying and the like; the device can provide current required for emergency power operations, the service life of the device can be prolonged, and the device is environment friendly and pollution free; the problems such that the use of lead-acid batteries causes environmental pollution and the lead-acid batteries need long-term maintenance can be effectively solved.

Description

technical field [0001] The invention relates to a direct current emergency power supply device. In particular, it relates to a DC emergency power supply device with a supercapacitor module capable of providing high-current charging and discharging. Background technique [0002] Supercapacitor (also known as electrochemical capacitor) is a new type of charge storage element, which has the advantages of large capacity, support for large current charge and discharge, long cycle life, good low temperature characteristics, environmental protection and no pollution, so supercapacitors are used in new energy, transportation Transportation, industry and other fields have broad application prospects. [0003] The traditional emergency power supply uses lead-acid batteries as the power source, but due to the poor low-temperature characteristics of lead-acid batteries, the output power is reduced when the temperature is low, the cycle life is short, and it needs to be replaced frequen...
