Embodiment Construction

[0026] Such as figure 1 As shown, an embodiment of the present invention is shown, an energy storage power supply system, including:

[0027] The main battery module 100 includes at least one single battery.

[0028] The backup battery module 200 includes at least one single battery connected in parallel with at least one single battery of the main battery module 100 .

[0029] The sampling module 300 is connected with the main battery module 100 and the backup battery module 200, and is used to collect the real-time voltage value and real-time current value of each single battery in use.

[0030] A control module 400, comprising:

[0031] The receiving unit 410 is connected with the sampling module 300 and used for receiving real-time voltage values ​​and real-time current values.

[0032] The timing unit 420 is configured to compare the real-time voltage value with the first threshold and the second threshold respectively, and calculate the transition time between the rea...

Abstract

The invention relates to an energy-storage power supply system and an energy-storage power supply method. The real-time voltage value and the real-time current value of each single battery in use and the conversion time of the real-time voltage value from a first threshold to a second threshold are acquired; the actual capacity value of each single battery in use is worked out based on the real-time voltage value, the real-time current value and the conversion time; the actual capacity value and a preset capacity value are compared so as to judge whether the capacity of each single battery in use decreases and whether the capacity meets the working standard; and further the power supply status of a main battery module and the power supply status of a spare battery module are controlled. Thus, that the original voltage parameter is not subject to change is ensured, overall replacement of the batteries or the power supply system is not needed, and the working life of the whole battery pack can be prolonged effectively.

Description

technical field [0001] The invention relates to the field of power supply, in particular to an energy storage power supply system and method. Background technique [0002] With the development of new energy technology and the popularization of life concepts such as environmental protection and low carbon, solar energy systems and new energy applications have received more and more attention. At present, they have been widely used in transportation, communication, ocean, meteorology, and other fields. Great application prospects. [0003] It is understood that the current life of solar panels can reach about 25 years, and the average life of battery packs as its energy storage device is only about 2-3 years, which restricts the development of solar energy systems and new energy applications. However, battery-type energy storage power supply systems such as solar cells are more and more widely used in the fields of industry and life. However, if it is widely used, it is impo...
