Abstract

The invention relates to a storage battery SOH real-time estimation system and method. The storage battery SOH real-time estimation system is characterized by comprising a lead-acid storage battery, astorage battery monitoring sensor assembly and a monitoring system assembly, the dynamic internal resistance value of the lead storage battery can be predicted in real time, complete charging and discharging experiments are not needed, and the service life of the battery is prolonged; the RBF neural network is constructed by adopting the dynamic internal resistance, temperature and electrolyte density of the battery, compared with the traditional BP neural network, the RBF neural network has stronger input and output mapping functions, the output result is more accurate, the real-time estimation can be realized, and the power failure overhaul is not needed.

Description

technical field [0001] The invention relates to the field of health state monitoring of lead-acid batteries, in particular to a system and method for real-time estimation of battery SOH. Background technique [0002] A large number of valve-regulated lead-acid batteries (VRLA) are used in the DC power supply equipment of the power system. Due to the high reliability and low maintenance workload of this valve-regulated lead-acid battery, the battery pack is actually in a state of no maintenance for a long time in many occasions, especially in unattended substations, which seriously deviates from the The basic requirements of battery operation and maintenance management, the battery pack is damaged much earlier than its nominal life. [0003] At present, domestic power supply and distribution stations generally adopt the battery terminal voltage monitoring method. In fact, the ability of voltage to represent the state of the battery is very weak; the battery monitoring and ma...
