Problems solved by technology

Therefore, if this method must establish relationship curves one by one according to various brands of batteries, it has the disadvantage of complicated application
In addition, the No. 6362601 battery status analysis method also involves the charging function. If the field device only needs the battery health status indication function, this method is not suitable for this requirement

Abstract

The invention is a method for diagnosing battery health state, comprising the steps of: providing discharge voltage and current data of a battery; setting a preset time interval and acceptable values of discharge current variation in the preset time interval; analyzing the changes of the discharge voltage and current data in the preset time interval; recording the discharge voltage and current data and the change data; comparing the discharge voltage data with the change data within the acceptable values of discharge current variation; and displaying the comparative result with a health state diagnosis pointer.

Description

technical field [0001] The present invention relates to a diagnostic method for the state of health of a battery, in particular to measuring the discharge voltage and discharge current data of the battery within a predetermined time interval to obtain changes in the discharge voltage and discharge current data as the state of health of the battery (State of health) Diagnosis method of the diagnostic pointer. Background technique [0002] With the development of science and technology in recent years, many computer-related instruments and equipment require high power quality. In the event of a power outage, these instruments and equipment, such as workstations, medical equipment, and production machines, may be severely affected or damaged. In order to meet the demand of providing stable power in time to prevent power interruption, batteries are generally widely used to provide high-quality power as backup power. In addition to providing high-quality power, batteries can al...
