Charge-discharge control system for storage battery

Abstract

The invention is applicable to the field of storage battery charge-discharge control and provides a charge-discharge control system for a storage battery. The charge-discharge control system is characterized in that a plasma exchanging film is disposed inside the storage battery to separate the interior of the storage battery into two parts, one part is filled with electrolyte, a water outlet is formed in the bottom of the other part, and the plasma exchanging film allows water molecules to pass and does not allow sulfate ions to pass; a partition is parallel with the plasma exchanging film and contacts with the same, and one end of the partition is connected with a linear motor; a voltage measuring unit is used for transmitting measured storage battery voltage to a controller, and the controller controls the linear motor to control the partition to move up and down according to the voltage of the storage battery so as to change the contact area of the electrolyte and the plasma exchanging film. The charge-discharge control system has the advantages that the contact area of the electrolyte and the plasma exchanging film is changed by measuring the output voltage change of the storage battery, so that the solution concentration of the electrolyte is adjusted, and the electrochemical reaction inside the storage battery is completed sufficiently to produce maximum power supply quantity; the charge-discharge control system is especially suitable for the storage batteries for sailing, aviation and mining fields.

Description

technical field [0001] The invention belongs to the field of storage battery charging and discharging control, in particular to a storage battery charging and discharging control system. Background technique [0002] As a reliable chemical energy source, batteries have been widely used in industrial fields such as power systems, transportation, and portable electronic shovels. For example, in the field of power system, due to its advantages of low emission and high energy use efficiency, it plays an increasingly important role in automobiles, such as supplying power to the engine when the engine starts, and powering the ignition system; generator voltage is low (overload ) or when not generating power (auxiliary) to supply power to the phase electrical equipment; store the excess energy of the generator, and the surge suppression function, etc. [0003] Because of its important role, vehicle batteries have developed to a greater extent, such as lead-acid batteries, nickel m...
