Charge and discharge control apparatus and intelligent battery

Abstract

The invention provides a charge and discharge control apparatus and an intelligent battery. The charge and discharge control apparatus comprises a servo module and an acquisition module. The acquisition module realizes acquisition and transmission of various parameters in the application process of a lead acid storage battery and enables a user to accurately grasp the state of the battery in real time. Besides, the acquisition module, according to the battery parameters, calculates conduction and breaking time of the battery and controls the servo module to perform charge and discharge control on the lead acid storage battery. Therefore, when the lead acid storage battery is at an abnormal state, loss of the lead acid storage battery can be reduced by interrupting or restarting charge and discharge of the lead acid storage battery. The acquisition module and the servo module complete maintenance of the battery together, enable the battery to be at an optimal working state, solve the problem of safety hidden risks of a standby battery of a base station, prolong the service life of the battery and reduce pollution to the environment.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a charge and discharge control device and an intelligent battery. Background technique [0002] Valve-regulated lead-acid batteries are often used as backup power in important places such as power rooms, data rooms, and mobile base stations. In recent years, the market capacity of global valve-regulated lead-acid batteries has reached tens of billions of yuan per year. [0003] Due to the great difference in the operating environment of valve-regulated lead-acid batteries, for many important places, the monitoring and maintenance of valve-regulated lead-acid batteries is necessary. At present, there are two main ways to monitor and maintain batteries in the industry: [0004] The first is manual inspection. Every once in a while (such as 3 months or half a year), engineering personnel arrive at the site to test the battery current, voltage, temperature, etc., and ma...

AI Technical Summary

Problems solved by technology

There are several disadvantages in manual inspection: because many base stations are located in remote areas, the investment of personnel and vehicle resources is large, which is time-consuming and laborious; power and computer rooms are important places, and the management of personnel entry and exit is very strict, and there may be hidden dangers of computer room failure when personnel enter the computer room

But it also brings new inconveniences: first, the wiring of the monitoring cable is complex, and it is easy to cause interference with strong electric cables, or even open circuit or short circuit; second, the ambient temperature cannot truly reflect the usage status of the battery, and cannot accurately judge the health of the battery conditions, resulting in the inability to carry out scientific maintenance and maintenance

[0006] Under the current technical conditions, the backup power supply of communication base stations usually has a rapid decline in capacity after about 2 to 3 years of use, and is forced to be scrapped in advance, causing a large amount of economic losses and environmental pollution

Or the battery is running at a low capacity, which shortens the backup time of the base station, thereby affecting the communication service quality of the base station, and there is a risk of communication interruption
