Barrier probability also presents different.Since the battery types of brand used on current electric energy meter are various, good and bad difficult point, battery quality is asked
Field electric energy table battery failures account for larger specific gravity caused by topic, are surveyed if the convenient and efficient performance to battery may be implemented
Examination carries out analysis and assessment to the service life on intelligent meter of battery, can be advanced by electrolytic cell and use the longevity on electric energy meter
Life, avoids the generation of failure, avoids user's dispute, promotes power supply service quality, promotes social harmony.
Secondly design defect in software causes dead battery capability there is also certain ratio, and electric energy meter is not complete when having a power failure
Enter low-power consumption entirely, completely into MCU work is frequently waken up after low-power consumption, into low-power consumption after wake up MCU when MCU being made to work
Between it is longer lead to dead battery capability, encounter similar failure, it is also desirable to field failure ammeter safeguard and solve.
In addition hardware design defect, which causes dead battery capability also, can occupy the ratio of part, and electric energy meter is larger when having a power failure
The device of power consumption is still with battery powered or MCU low-power consumption indexs are relatively high leads to dead battery capability.
Battery discharge maintains the storage data and clock of electric energy meter when intelligent electric energy meter has a power failure.Battery installation to electric energy meter
Discharge curve after on electric energy meter is without adequately measuring, analyzing and studying, and to battery, service life is done on electric energy meter
The reckoning for having gone out mistake, occurs the low problem of various cell voltages so as to cause electric energy meter in using operational process.
