Recorder for storage battery condition

Abstract

The invention relates to a recorder for storage battery condition. The recorder comprises a direct current voltage regulation module, a voltage acquisition module, a current acquisition module, an analog-to-digital conversion module, a data processing module and a storage module, wherein due to instability of storage battery voltage, stable voltage is acquired through the direct current voltage regulation module to provide stable voltage power supply for the current acquisition module, the analog-to-digital conversion module and the storage module; the system can operate reliably; voltage variation of the storage battery is collected, and voltage data is provided through the voltage acquisition module; current information is acquired by applying a sampling resistor and an operational amplifier through the voltage regulation module; analog amount collected by the current acquisition module and the voltage acquisition module can digitize through the analog-to-digital conversion module, so that convenience is provided for the data processing module to conduct processing; the core of the data processing module is a single-chip microcomputer; timing control, acquisition sequence control of the current and the voltage are realized through programming; data exchange between an SD card and the single-chip microcomputer is realized through an SPI communication protocol; data storage is realized.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to the recording of the working state of a storage battery, in particular to a storage battery voltage and current state recorder. Background technique [0002] With the development of society, electric vehicles have become the best means of transportation. As the best power source for electric vehicles, batteries are used by some users viciously violating the regulations. Some people ask the manufacturers to replace the batteries within the warranty period, and they will perform some illegal operations on the batteries when the batteries are approaching the shelf life. , such as super-large current discharge, not charging in time after over-discharge, etc., which will lead to a sharp shortening of the battery life, or even unusable. At the same time, this also brings unnecessary losses to battery manufacturers. [0003] Through searching information, it is found that...

Problems solved by technology

As the best power source for electric vehicles, batteries are used by some users viciously violating the regulations. Some people ask the manufacturers to replace the batteries within the shelf life, and they will perform some illegal operations on the batteries when the batteries are approaching the shelf life. , such as super-high current discharge, not charging in time after over-discharge, etc., which will lead to a sharp shortening of battery life, or even unusable

At the same time, this also brought unnecessary losses to battery manufacturers.

[0003] Through searching information, it is found that at present, there are only state recording instruments for large transportation vehicles such as airplanes, trains, and automobiles at home and abroad, which are usually called black boxes.

However, there are relatively few studies on state recording instruments for small machines such as batteries.

The manufacturer has clear regulations on the service life of the battery, but some illegal operations during use will greatly reduce the working life of the battery. Usually, the manufacturer cannot know what illegal operations have occurred during the use of the battery. This will cause a certain economic loss, and some recorders are too expensive at present, and are not suitable for recording working conditions such as electric vehicle batteries.
