Lead-acid battery internal formation charging and discharging power supply

Abstract

The invention provides a lead-acid battery internal formation charging and discharging power supply, which comprises a lead-acid battery, a first electrolytic capacitor, a second electrolytic capacitor, an inductor, a first IGBT (Insulated Gate Bipolar Transistor) and a second IGBT, wherein a positive electrode of the lead-acid battery is connected to an emitting electrode of the first IGBT and an emitting electrode of the second IGBT through the inductor. The lead-acid battery internal formation charging and discharging power supply adopts an IGBT module and a control and regulation circuit thereof to form high-frequency PWM direct current chopping with the frequency being controllable in a range from 5HZ to 1KHZ, thereby not only being capable of realizing an internal formation operating mode of positive and negative pulse charging, but also being capable of realizing an internal formation operating mode of constant-current charging and constant-current discharging, and being simple in circuit structure; polarization of the battery can be removed effectively, the consumption of electric energy is reduced, more than 40% of energy can be saved, the working time is saved, temperature rise of the battery can also be reduced, acid gas evolution is reduced, and pollutions for the atmospheric environment are reduced; and the capacity of the battery can be improved, and no harmonic pollution is imposed on the power grid.

Description

technical field [0001] The invention belongs to the technical field of electric power and energy, and in particular relates to a lead-acid storage battery internalized into a charging and discharging power supply. Background technique [0002] As the awareness of energy conservation and environmental protection gradually penetrates into the hearts of the general public, the use and replacement of existing mobile power sources such as batteries or battery packs are becoming more and more frequent. At present, most of the battery chargers in the domestic market use high-frequency PWM control. The externalization of the acid storage battery will pollute the environment. Therefore, it is necessary to make necessary energy-saving and environmental protection improvements to the existing lead-acid storage battery in the form of charging and discharging. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of this invention is t...
