The invention relates to the field of power supply management, and discloses a capacitor switching management method, a capacitor switching management device, a standby power system and a solid state disk. The cache corresponding to the business activity is divided into an active area, an adjusting area and a non-active area, different areas comprise corresponding capacitor banks, the capacitor banks of the active area and the adjusting area are in an open state, and the capacitor bank of the non-active area is in a closed state. When the business exceeds the threshold value, standby power adjustment is carried out, and business operation is completed when the expected business is powered down. When the standby power is adjusted, the adjusting area can be used as an active area to receive the business volume, so that the continuous operation of the business is ensured, and the business loss risk caused by abnormal power failure is reduced. The number of the capacitor banks corresponding to the active area, the adjusting area and the non-active area is adjusted, so that the capacitance of the three subareas is at the optimal value, thereby not only meeting the requirement of real-time business activity, but also improving the standby power utilization efficiency and prolonging the business life of the standby power system.
Description
technical field [0001] The invention relates to the field of power supply management, in particular to a capacitor switching management method, a capacitor switching management device, a power backup system, and a solid-state hard disk. Background technique [0002] At present, the protection methods for dealing with abnormal power failure in the design of many electronic systems mostly use the backup power system to maintain the power supply for a period of time, so as to ensure the complete convergence of the business. within volatile memory. Most of the backup power system uses a supercapacitor bank composed of multiple capacitors as an energy storage unit, which is charged when the system is powered on, and discharged as a power supply when the system is powered off (such as abnormal power failure). [0003] As the business changes, the capacitance capacity of the backup power system required changes. In the process of adjusting the backup power demand, there is a certa...
