Battery capacity and internal resistance of the two relations which has two meanings: -Shenzhen Power Kingdom Co., Ltd.

( 1) Battery internal resistance and charged state of the relationship between the battery charged state refers to the battery SOC can release the capacity of the compared to its rated capacity. The data of post and telecommunication power supply system and are using the power battery is very important. In 1992 David O Feder published with MIDTrONic Celltronand Midtron conductivity tester of valve-control sealed lead-acid battery ( VRLA) Test and statistical results. Figure 1 shows the 336 pieces of 1000 ah sealed lead-acid battery with 263 discharge to 1 A. With battery conductance (80 V of the discharge time The reciprocal of resistance) The distribution of. As you can see, there is a linear relationship between them, the correlation coefficient R2 = 0. 825. Thus been suggested for online use of valve-control sealed lead-acid batteries, can use the measured conductance value to speculate that their surplus capacity. Although more than a decade ago I from objective reality have repeatedly puts forward negative views on this view, and recognized by numerous peer experts. But today there are still some people didn't do test automatically refer to the above outdated ideas, and told you that view & # 39; The problem & # 39; 。 1 valve-control sealed lead-acid battery current control valve opening sealed lead-acid battery has gradually replace type liquid electrolyte lead-acid batteries, widely used in post and telecommunication power supply, UPS, energy storage power system, etc. Power valve control type sealed lead acid battery not only has been widely used in electric moped, and march to light electric vehicles vigorously again recently. These fields require online test battery charged state.
