The present invention provides a storage battery capacity curve drawing method and device, wherein the method includes: after the system is powered on, reading the actual database in the hard disk, the actual database records the history of each storage battery managed by the system Electricity information, drawing a historical curve of battery capacity according to the historical electric quantity information recorded in the actual database; when it is detected that there is a battery whose electric quantity has changed in each of the batteries, the electric quantity information of the battery whose electric quantity has changed is stored in In the actual database and the internal memory; when a battery capacity curve drawing command is detected, continue drawing along the historical curve of the battery capacity according to the power information recorded in the internal memory. Through the present invention, the number of memory accesses to the hard disk is reduced, thereby reducing the waste of memory resources and CPU resources, improving the processing speed of the system, and ensuring the query speed of data and the normal drawing of historical curves.
Description
technical field [0001] The invention relates to the field of storage battery management, in particular to a method and device for drawing storage battery capacity curves. Background technique [0002] At present, the high-voltage DC power supply system has gradually replaced the UPS (Uninterruptible Power System / Uninterruptible PowerSupply, uninterruptible power supply) system due to its advantages such as high reliability, strong maintainability, intelligent battery management, and high efficiency and energy saving. It is widely used by the public. High-voltage DC The power system includes battery packs, battery management systems and power generation devices. [0003] In the storage battery management system, it includes a function for the user to query and display the output voltage and output current of each storage battery, and process the above data in the form of historical data; at the same time, the output voltage and output current of each storage battery The outp...
