Abstract

The invention discloses a supercapacitor module and a storage system. The module comprises an energy storage module, a boosting module and a controller, wherein the energy storage module consists of aplurality of energy storage capacitors; and the boosting module is connected with the energy storage module and is used for boosting voltage output by the boosting module according to control of thecontroller when the energy storage module carries out discharging and discharging voltage is reduced to a threshold value, so as to satisfy a load need until end-off voltage is obtained. The boostingmodule is added between the load and the energy storage module, the end-off voltage of the energy storage module can be set to be relatively low and the discharging voltage difference is correspondingly reduced, so that the capacity of the released capacitor is improved. Moreover, due to the action of the boosting module, the load can receive constant voltage and is not easy to be influenced by voltage reduction of the capacitors. Finally, due to the advantages of the module, the storage system can have a longer allowed backup time and higher reliability after a main power supply is power down.

Description

technical field [0001] The invention relates to the technical field of power backup, in particular to a supercapacitor module and a storage system. Background technique [0002] The storage system is an important part of storing data, and the sustainability of its power supply is an indicator that cannot be ignored. Usually, the storage system needs to perform data backup when the PSU (power supply unit) is powered off. One of the backup solutions is to use a super capacitor module (also called a CBU capacitor backup module) as an energy storage unit. The capacitor module usually exists as a separate module, and it is arranged in a dedicated position inside the machine in the whole machine. [0003] In the prior art, the supercapacitor module is composed of several (usually 5) capacitors connected in series. Since most devices in the storage system use 12V voltage as the input voltage, the supercapacitor module usually uses 12V voltage as the reference input and output vol...
