Conventional smart water meters use a built-in lithium battery when controlling the opening or closing of the water valve. After the lithium battery has been used for a certain period of time, it cannot supply energy to the control circuit and has to replace the battery. It is ...
In smart toys, some often require instantaneous large currents, and the battery can not provide. Combining supercapacitors with batteries can solve this problem. Supercapacitors can also be used as power sources to power smart toys, which not only reduces the cost of use but ...
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 ...
