Embodiment Construction

[0017] The specific embodiments of the present invention will be described in further detail below. It should be understood that the descriptions of the embodiments of the present invention herein are not intended to limit the protection scope of the present invention.

[0018] like figure 1 As shown, it is a schematic structural diagram of a power control type battery management system for a base station energy storage battery insertion box provided by the present invention. The power control type battery management system for the base station energy storage battery insertion box is electrically connected with the mains module 100, the base station load device 200, and the air conditioner and lighting. The mains module 100 usually refers to power frequency alternating current (AC), which is represented by three commonly used quantities of alternating current: voltage, current, and frequency. 5G equipment rooms generally introduce three-phase 380V, 50HZ mains as the power sup...

Abstract

The invention discloses a power control type battery management system for a base station energy storage battery subrack. The power control type battery management system comprises a DC / DC (Direct Current / Direct Current) conversion module and a battery management unit, the DC / DC conversion module is used for converting alternating current output by the commercial power module into direct current and comprises an AC / DC rectification module, a multiphase bidirectional BUCK / BOOST current controller and a control module. And the control module is used for controlling the charging and discharging voltage and current of the AC / DC rectifier module according to the working condition of the base station energy storage battery plug-in box. The control module controls the magnitude of voltage and current output by the AC / DC rectifier module and controls the multiphase bidirectional BUCK / BOOST current controller according to parameters collected by the function sensor. The battery management system not only can be matched with batteries of different voltage systems, but also can realize constant-voltage output of the battery pack due to dynamic adjustment of the input voltage or the input current, and meets the use requirements of a base station.

Description

technical field [0001] The invention relates to the technical field of power management and control of communication base stations, in particular to a power control type battery management system used for base station energy storage battery insert boxes. Background technique [0002] In order to solve the problem of recycling the power battery of new energy vehicles, one of the recycling methods is to use the power battery in the base station backup system. However, the performance consistency of the recycled old power battery cannot be guaranteed. When the battery pack is charged and discharged in parallel, the voltage and current distribution of the battery pack are inconsistent, which shortens the service life of the old power battery pack and increases the operation and maintenance cost. In the lithium battery industry, a battery pack is defined as a number of batteries connected in series in a certain shape and electrically connected to the PCB board in series or in par...
