A cascade utilization method of power battery based on photovoltaic base station

Abstract

The invention discloses a gradient utilization method of a power battery based on a photovoltaic base station, comprising: screening the discarded power battery by a battery sharing manager, groupingnew and old battery with different models and capacities, eliminating the battery with a depreciation rate exceeding a threshold value, screening the discarded power battery, grouping new and old battery with different models and capacities, eliminating the battery not conforming to the requirement by big data. The gradient battery is used to gradually replace the lead-acid battery in stock, so asto realize full utilization of resources, weed out lead-acid battery gradually and avoid waste of resources. The battery utilization process provided by the invention can ensure the parameter requirements of gradient battery utilization, and effectively avoid the waste and damage of the battery; the screening method is accurate and efficient, so the safety and reliability of gradient battery utilization can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of mobile communication batteries, in particular to a cascade utilization method of a power battery based on a photovoltaic base station. Background technique [0002] The performance indicators of the cascade battery are better than those of the lead-acid battery, fully meeting the base station application. Compared with lead-acid batteries, cascade batteries have certain advantages in cycle life, energy density, high-temperature performance, etc., and various performance indicators are better than lead-acid batteries. The cascade battery technically fully meets the backup power requirements of various working conditions of the existing network. The cascade battery with different cycle life is suitable for different application scenarios, and the economic benefits are obvious. [0003] At present, there are three main application methods of cascade batteries: cell-level reorganization scheme, module-level ...

Problems solved by technology

[0004] There are some utilization methods for cascade batteries in the prior art, and there are some technical problems in the existing methods, such as the technical scheme of patent No. CN102396099, which utilizes the utilization of cascade batteries by recycling the negative plates of waste lead-acid power batteries, Its recycling process is complicated and the recycling cost is high; for example, the existing technical scheme, its power battery recycling steps include (1) appearance identification, (2) performance characteristic analysis, (3) microstructure change, and its advantage is that it can pass non-destructive testing Means and methods to screen cascade utilization of power batteries, but its disadvantages are that the screening steps are too simple, the classification method is rough, and the matching rate of power batteries after screening is low.
