Problems solved by technology

[0004] Due to the above two important influencing factors, in actual use, batteries are maintained or updated according to a certain period of use, which virtually causes a lot of unnecessary waste to battery manufacturers and battery users. At the same time, battery users It is also impossible to accurately and systematically understand the state of the battery currently in use

Abstract

The invention discloses a method for monitoring capacity of a storage battery. The method comprises the following steps of: 1) judging whether the current storage battery is fully charged or not in a charging process; and 2) judging whether the current storage battery is fully discharged in a discharging process. The method can provide a real-time and accurate capacity value for a storage battery user; and by the method, the storage battery user can judge whether the current storage battery meets the requirement of the user or not; when the floating time of the storage battery in the charging process is long, the charging energy is wasted, and when the over discharge frequency of the storage battery in the discharging process is great, the service life of the storage battery is shortened; and the method can provide scientific and accurate judgment for the storage battery user so as to avoid the phenomena of floating, over discharge and the like.

Description

technical field [0001] The invention relates to a method for accurately monitoring the capacity of a storage battery and the use state of the storage battery, and belongs to the technical field of storage batteries. Background technique [0002] There are a variety of devices or functions for battery capacity display on the market, and the main measurement method is to use the terminal voltage as the measurement parameter. However, during the use of the battery, floating charging and over-discharging often occur. At the same time, the terminal voltage of the battery changes nonlinearly during the discharge or charging process, so it is difficult to accurately measure the actual capacity of the battery. [0003] For rechargeable batteries, the entire industry mostly uses the number of fully charged and discharged times as an important measure of the quality of rechargeable batteries during monitoring. However, since the capacity of the battery will change after each use, tha...
