Integrated managing device and its managing method for accumulator charging and discharging

Abstract

This invention discloses a charge-discharge integration manager of storage batteries including: a charge-discharge device for dynamically monitoring the charge-discharge state of at least two sets of batteries on-line and outputting discharge control signals, controlling the battery set meeting the discharging condition to execute the discharge action and outputting charge signals to execute charge action to the battery set meeting the charge condition and on-line testing the residual quantity change of electricity and pre-setting charge parameter value based on the tested environment temperature. This invention also discloses a management method of the manager.

Description

technical field [0001] The invention relates to the field of low-voltage direct current power supply using storage batteries, in particular to a manager for integrated charge and discharge management of a single battery or multiple batteries, a management system and a management method using the manager for control. Background technique [0002] Batteries have stable voltage and reliable power supply, and are widely used in various departments such as power plants, communication systems, electric vehicles, aerospace, and ship transportation. In many fields, the main function of the battery is to use it as a starting power supply; the other is to use it as a backup power supply. For example, there are a large number of electrical equipment on ships that must be powered by DC low-voltage systems. When the main generator and emergency generator fail, the low-voltage power supply system must supply power to the equipment. Therefore, the low-voltage system composed of battery pac...

AI Technical Summary

Problems solved by technology

It cannot effectively manage the battery pack, and the management and maintenance of the battery pack still need to be completed by the operator, so there are deficiencies: 1. The charging and discharging equipment adopts centralized control. Since the distance between the equipment and the battery pack is not equal, the charging The inconsistency of the charging voltage caused by the line loss during the time directly affects the charging quality of the battery pack; 2. Due to the low over-discharge point set by the equipment, the battery pack cannot be charged in time after conversion, and the battery is in a state of power loss and deep discharge 3. The equipment cannot dynamically track the usage status of the battery. Under human intervention, it is difficult to guarantee the service life of the battery. 4. The volume and power consumption of the equipment are too large. Under the condition of limited power on board, Excessive loss will increase the burden on the power system and waste limited power resources
