Abstract

This invention discloses a management device for charging and discharging a vanadium battery, comprising a first electrolyte circulation magnetic pump, a second electrolyte circulation magnetic pump, a boost controller, a divider resistor, a stabilivolt, a first relay, a second relay, a first diode, a second diode, a third diode and a forth diode. The management device for charging and discharging the vanadium battery is consolidated into a bridge rectification circuit through the boost controller and the divider resistor , so that the management device for charging and discharging the vanadium battery can easily perform inversion and voltage-boosting control on the power supply of the vanadium battery, optimizes the control for the charging loop and the discharging loop of the vanadium battery, reduces electronic members and cost, and facilitates generalization.

Description

technical field [0001] The invention relates to an accessory device of a vanadium battery, in particular to a charging and discharging management device for a vanadium battery. Background technique [0002] The solar device charges the vanadium battery, and the positive and negative electrolytes undergo electrolytic reactions in the reactor inside the battery. Since the vanadium battery has a certain withstand voltage range, and the solar output voltage may vary greatly with the light intensity, the charging voltage exceeding the maximum withstand voltage of the vanadium battery can destroy the battery reactor, cause the positive and negative electrolytes to lose their electrolytic sites, and even destroy the chemical properties of the electrolyte. . [0003] The output of the vanadium battery is direct current, while household equipment uses alternating current, and the magnetic pump that drives the electrolyte circulation also uses alternating current. The circulating ma...
