Embodiment Construction

[0039] In order to solve the technical problems raised in the background art, the inventor of this application thought of providing a control unit, multiple cell detection units, and multiple isolated charging and discharging units in the battery pack online management system, and the cell detection units collected in real time and connected in parallel. The charge and discharge status information of the battery, and upload the collected information to the control unit in real time. The control unit calculates the charge and discharge parameters corresponding to each battery according to the received charge and discharge status information of each battery, and sends the charge and discharge parameters to The corresponding isolated charge and discharge unit, the isolated charge and discharge unit performs charge control or discharge control on the connected battery according to the received charge and discharge parameters. Therefore, on the one hand, the battery status detection ...

Abstract

The present invention discloses a battery pack online management system. The system includes a control unit, a plurality of cell detection units and a plurality of isolated charging and discharging units. Each of the cell detection units is connected in parallel with a corresponding storage battery. The input terminal of each of the isolated charging and discharging units is respectively connected to a corresponding battery interface, and the output ends are connected in parallel with different interfaces of the same DC bus; the control unit is respectively connected to the control terminal of each of the cell detection units and each of the isolated charging and discharging units; and each cell detection unit is configured to collect the charging and discharging status of the corresponding battery Information, and uploads the collected information to the control unit; the control unit is configured to calculate the charging and discharging parameters of each storage battery according to the received charging and discharging status information, and sends the charging and discharging parameters to the corresponding isolated charging and discharging unit; and each isolated charging and discharging unit is used to charge and discharge the connected batteries according to the charging and discharging parameters. It can be seen that the present invention improves the battery state detection efficiency and is favorable for energy saving and emission reduction.

Description

Technical field [0001] The invention relates to the technical field of storage batteries, in particular to an online management system for storage batteries. Background technique [0002] As a technical means of uninterrupted power supply, battery packs are widely used in communications, power, finance and other industries. Through years of procurement and operation, various industries have accumulated a large number of batteries of different specifications and different manufacturers. [0003] Existing battery status detection requires maintenance personnel to go to the site to remove the battery from the power supply system and connect it to the battery detection protection device. This process is time-consuming, laborious and inefficient, and it is difficult to maintain a large number of batteries such as base stations and radar stations. , Affect the life of the battery. During the battery status detection process, if problems such as AC power failure or rectifier failure occu...
