Abstract

The invention relates to a detection method and a detection device for storage battery surplus capacity. According to the detection method and the detection device, a plurality of capacitance predicted values and a plurality of surplus capacity predicted values of a storage battery to be detected are obtained by utilizing an artificial neural network model library and measured values of influencing factors of the surplus capacity, the plurality of capacitance predicted values are subjected to weighted fitting, a capacitance measured value is regarded as a target value, a capacitance fitted value is optimized by adopting a particle swarm algorithm so as to obtain an optimized weight coefficient, and the plurality of surplus capacity predicted values are subjected to weighted fitting by utilizing the optimized weight coefficient, so as to obtain a surplus capacity value of the storage battery to be detected. The artificial neural network model library is used in the detection method and the detection device, the plurality of accurate surplus capacity predicted values can be generated, the optimized weight coefficient is obtained by adopting a particle swarm algorithm after the plurality of surplus capacity predicted values are subjected to weighted fitting, so that the plurality of surplus capacity predicted values after weighted fitting are more close to an actual surplus capacity value of the storage battery to be detected, and the detection precision of the surplus capacity value is further improved.

Description

technical field [0001] The invention relates to the technical field of electric power information, in particular to a method and a device for detecting the remaining capacity of a storage battery. Background technique [0002] The storage battery is a low-cost, easy-to-use, and simple-structure power supply device, which is widely used in various industries such as electric power and communication. The stable and reliable operation of the battery is crucial to the operation of the entire system. In order to fully understand the working state of the battery, it is necessary to detect the remaining capacity (SOC, State of Charge, state of charge) of the battery in order to take corresponding control measures. [0003] Generally, the detection of the remaining capacity of the battery adopts the discharge test method, the internal resistance detection method and the open circuit voltage method. The discharge test method needs to determine the initial capacity and charge-discha...
