Embodiment Construction

[0052] Further description will be made below in conjunction with the accompanying drawings.

[0053] see figure 1 , a multifunctional intelligent maintenance device for lead-acid batteries, comprising a charging unit 1, a main control module 2, a discharging unit 3 and a measurement control circuit 4, wherein:

[0054] The aforementioned charging unit 1 provides charging power for the lead-acid battery pack, including an input rectification and filtering circuit 1.1 and a switching power supply module 1.2, and the input rectification and filtering circuit 1.1 is connected to the switching power supply module 1.2.

[0055] After the battery pack is correctly connected, the output switching switch B4.3 is disconnected, and the 220V AC power is converted into a 310V DC high voltage by the input rectification filter circuit 1.1, and then converted into about 14.4V by the DC / DC switching power supply module 1.2. Control the direct current, supply power for the storage battery thr...

Abstract

Relating to maintenance technologies of lead-acid batteries, the invention provides an intelligent maintenance device of a multifunctional lead-acid battery and a capacity prediction method. The intelligent maintenance device of a multifunctional lead-acid battery in the invention is used for on-line test of lead-acid battery capacity, automatic constant current charge and discharge, as well as capacity recovery of a degraded battery. The device comprises a charging unit, a discharging unit, a master control module and a measurement control circuit. The provided lead-acid battery capacity prediction algorithm through BP neural network optimization based on genetic annealing can be realized in the control module and an upper computer, and the capacity prediction error is smaller than a 15%prediction error of present domestic battery capacity rapid testers. The device of the invention can be used in on-line health status test of lead-acid battery capacity and can realize capacity recovery of a degraded battery, as well as extend the battery service life.

Description

technical field [0001] The invention relates to an intelligent maintenance device and a capacity prediction method of a multifunctional lead-acid storage battery, which is an intelligent maintenance device for performing automatic constant current charging and discharging, capacity prediction and capacity recovery of a deteriorated battery for a lead-acid storage battery. Background technique [0002] Lead-acid battery is an energy storage element with a history of more than 100 years. Due to its low price, stable performance, mature technology and manufacturing process, it is widely used in many application fields such as electric power, communication, automobile and electric vehicle. Compared with ordinary lead-acid batteries, valve-regulated sealed lead-acid batteries use internal oxygen recombination technology, which greatly alleviates the loss of electrolyte, so that the batteries can serve for a long time without maintenance, and have the advantages of small size, expl...
