A management device and method for parallel connection of different types of battery packs

Abstract

The invention discloses a management device and method for parallel connection of different types of battery packs, including a monitoring module, a charge management unit, a discharge management unit, a DC power distribution unit and an AC power distribution unit; The parallel battery of the group is connected with the power environment monitoring host; the mains input supplies power to the charging management unit through the AC power distribution unit; The battery is charged; the discharge management unit is connected to the DC power distribution unit, and the discharge management unit manages the simultaneous discharge of multiple groups of the batteries to the load circuit by sequentially controlling the DC power distribution unit and the switch circuit; The switch circuit is configured for switching between the load circuit and the charging management unit. Realize the parallel use of multiple battery packs of different types, different capacities, and different ages.

Description

technical field [0001] The invention belongs to the technical field of storage batteries, and in particular relates to a management device and method for parallel connection of different types of storage battery groups. Background technique [0002] With the development of modern mobile communication technology, the construction of communication base stations is becoming more and more extensive. As a common backup power source, batteries have become an important part of the power supply system of communication base stations and play a pivotal role in the construction of communication base station power systems. As a power source, batteries are widely used in the field of communication power supplies. Most of the current usage conditions are that each independent communication power supply system is generally equipped with at least two sets of batteries to improve the safety of battery power supply and prevent communication interruption accidents caused by damage to one set o...
