  At present, with the increasingly intelligent function of electric meters, long-term data storage and display functions are indispensable. Many electric meters use various batteries to supply power to the clock chip and power-off protection. At present, supercapacitors can fully realize this function. And it has an advantage over using a battery.   The traditional method commonly used in electric meters is to install a lithium battery. When the external power supply is cut off, the voltage of the lithium battery is insufficient or under voltage. Randomly, if the battery is not accurately and timely monitored, the clock circuit will be timed. An error caused the billing or billing error. In order to avoid this phenomenon, the smart meter uses an external supercapacitor. When the battery is under voltage or low, it automatically switches to the supercapacitor to supply power to the clock circuit, thus ensuring the reliability of the entire system and ensuring the country and c...
